Administering and Monitoring the Upgrade of SOA Instances

9 Administering and Monitoring the Upgrade of SOA Instances

Describes how open and closed SOA instances are upgraded to 12c (12.2.1) and the options a user has to administer and monitor the upgrade process.

The standard upgrade process for SOA Suite and BPM 12c provides an automated solution that will upgrade your open and closed instances. The upgrade of closed instances can be monitored and configured with the administration scripts described in the following sections:

Understanding the Instance Upgrade Process

The Upgrade Assistant framework delegates the upgrade of schemas to respective component installations (MDS, ORASDPM, OPSS, SOA, etc.) During the 12c SOA upgrade, the Upgrade Assistant can also upgrade instances.

What is being upgraded?

The SOA installation will also upgrade various components as part of upgrade process, including _MDS schema and the _SOAINFRA schema. The _SOAINFRA schema contains the following schema components:

Schema definitions - such as tables and indexes
Metadata - the data required to run the SOA server and SOA composites

Note:

The BPM metadata upgrade begins once you log into Business Process Composer 12c (12.2.1) for the first time (after a successful upgrade).

For more information on using Business Process Composer, see Developing Business Processes with Oracle Business Process Composer.
Instance Data - the data created by the various composites. Instances can be open or closed.

How are these components upgraded?

During the 12c schema upgrade process, it is important to understand the order in which UA performs the upgrade of these components.

The upgrade occurs in four distinct stages:

Upgrade Assistant will upgrade 11g schema definitions.
Upgrade Assistant will then upgrade 11g metadata and create background control jobs to upgrade open instances.

NOTE: This process may be time consuming as the jobs will continue to run within UA until the final database job finishes upgrading the open instances. It is important not to close the Upgrade Assistant until the final job is complete.

For example, the time required to upgrade instances depends on the following:
- Size of prefix_SOAINFRA schema (number of open and closed instances)
- System configuration (such as the number of CPI's (cores), memory usage, disk I/O configuration).
- Speed of the system and size of driver tables
Once all of the open instances have been upgraded, the background jobs begin upgrading the closed instances. Note that the upgrade of closed instances continues to run in the background even after you close the Upgrade Assistant. However, if the background job is stopped, and there are still closed instances to be upgraded, then you must restart them with the administration scripts.
Finally, once the last job finishes upgrading the open instances, the Upgrade Assistant provides the upgrade status and lists the next steps to take in the upgrade process.

You should review the Upgrade Success screen of the Upgrade Assistant to determine your next steps based on the information provided. NOTE: If you are running in -response (silent) mode, this information will be listed in the UA stdout file.
- If the Upgrade Assistant reports that there are no additional instances to be upgraded, then simply close the Upgrade Assistant UI and continue with the remaining upgrade procedures (launching the Reconfiguration Wizard for example).
- If the Upgrade Assistant reports that there was an error during the instance upgrade, then correct the error(s) and resubmit the database job to complete the upgrade. You can also use the Report Upgrade Summary administration script (Option 1) to check the UPGRADE ERROR COUNT section of the report.
- You will be notified that the upgrade of the closed instances will continue in the background after you close the Upgrade Assistant. Do not close the Upgrade Assistant until UA reports it is finished and you see the following:
```
Oracle SOA
1. The Upgrade Assistant has successfully upgraded all open instances. You can now close the Upgrade Assistant.
2. The automated upgrade of closed instances will continue in the background after the Upgrade Assistant is exited and until the SOA server is started,at which point the upgrade will stop. You can schedule the upgrade of any remaining closed instances for a time when the SOA server is less busy.
Close the Upgrade Assistant and use the instance data administration scripts to administer and monitor the overall progress of this automated upgrade. For more information see "Administering and Monitoring the Upgrade of SOA Instance Data" in Upgrading SOA Suite and Business Process Management. 
```

Note:

The upgrade of closed instances will continue until all instances have been upgraded or the middle tier is started (such as the SOA managed server, for example.)

If the middle tier is started before all closed instances are upgraded, then the upgrade job will stop. You will have to use the administration scripts to manually restart the upgrade.

Understanding Instance Upgrade Background Jobs

The background jobs are created by Upgrade Assistant during the _SOAINFRA schema upgrade. These jobs run in the background and automate the upgrade of the open and closed instance data. It is important to understand how these jobs operate within the upgrade process and how you can manage them. The list below describes some important information about these jobs:

Jobs are created by Upgrade Assistant (UA), but they are managed through administration scripts. You can use the administration scripts to configure how and when these jobs will run, for example.
Jobs are automatically started after the schema upgrade process.
Jobs that are initiated through UA are automatically stopped when one of the following occurs:
- The job is complete and all closed instances are migrated to 12c
- A middle tier application is started (a managed server, for example)
- The Stop Jobs script (Option 8) is started
If closed instances have not yet been upgraded, then the background jobs will continue to run in the background - even after the Upgrade Assistant has been closed.
If the job is stopped, and there are still instances to be upgraded, you can enable and schedule the jobs to run at another time using the administration scripts.

For more information on configuring the background jobs, see: Enabling and Disabling Background Control Job (Option 6), Stopping Upgrade Sessions and Jobs, and Restarting an Incomplete Upgrade.

Understanding the Flow Trace Changes in 12c

In 12c SOA, instances are controlled using flowIDs instead of ECIDs. When the Upgrade Assistant upgrades instances from 11g SOA to 12c SOA, there are few differences between the 11g upgraded flow instances and the newly created 12c instances. These differences will not impact the functionality of the flow trace, but it is important to note the differences.

The flow trace XML examples below show the following differences:

The attributes ActionType and ActionName are new in 12c and are not available in 11g upgraded instances.
Date and lastUpdatedDate are the same for 11g Upgraded instances.
ElapsedTime for Entry Instance Id is 0 for 11g Upgraded instances.

Flow trace XML for 11g to 12c upgraded instances:

================================
 <audit_trail

In addition, the Recovery status of the new instances created in 12c for a caught fault in BPEL shows the fault as recovered as shown in Figure 9-1:

Figure 9-1 New 12c Instance Flow Trace

Description of "Figure 9-1 New 12c Instance Flow Trace"

However, the Recovery status of an upgraded 11g instance for a caught fault in BPEL shows the fault as Nonrecoverable as shown in Figure 9-2:

Note:

The information passed from the 11g faults is not enough to correctly identify the state of a fault. To handle this, all the actual faults retrieved from 11g are initially identified as nonrecoverable. Dummy faults are then created to set the proper state (BPEL_invoke_recovery, Bpel_activity_recovery).

Therefore, if you see a warning or notice that the 11g faults are nonrecoverable, you can ignore the warning.

Using Purge Scripts Before You Upgrade

Use the purge scripts before you start the instance upgrade to purge the closed 11g instances that you do not need in the upgraded 12c environment. The 12c purge scripts will include non-migrated closed instances. This means that post upgrade, if you schedule to run 12c Purge scripts, the scripts will purge non-migrated closed instances. Using the purge scripts to remove closed instances can help improve the overall performance of the upgrade.

Note:

When upgrading open instances only, you may see an aborted status flow. A flow will be in an aborted state if the child flow was aborted in 11g.

All composite instance associated with this ECID will remain in terminated state.

For more information on using Auto Purge or purge scripts, see Managing Database Growth.

Caution:

Do not schedule purge jobs to run while the Upgrade Assistant background jobs are running. Running the scripts while Upgrade Assistant is running can cause the purge or upgrade to fail.

If you do configure purge scripts to run while Upgrade Assistant is running, you will see: "ORA-20099: ERROR The 11g to 12c Upgrade is in progress".

If you run UA while purge scripts are running, you will see: "SQLException: ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired".

Using the Upgrade Administration Scripts

The upgrade administration scripts are included as part of the Upgrade Assistant functions provided with the SOA Suite installation. These PL/SQL scripts provide additional administrative control over the upgrade of instances. Once upgraded, the instances can be viewed from Oracle Enterprise Manager Console. If more detailed information is needed about the upgrade progress, then use the administration scripts for additional reporting and configuration options.

Note:

The administration upgrade scripts provide detailed information about the upgrade. These scripts provide additional configuration, administration, and monitoring functionality for your instance upgrade. You can configure these scripts to run (or not run) based on your own requirements.

The Fusion Middleware Control Console can also be used to administer and monitor the upgrade process, but you will have more administration options using the administration scripts.

Oracle recommends that you run the Report Upgrade Summary (Option 1) script after using the Upgrade Assistant to monitor Upgrade of closed instances.

For more information about using the Fusion Middleware Control Console to monitor the progress of the upgrade, seeMonitoring Upgrade Status with Fusion Middleware Control.

Accessing the Upgrade Scripts Menu

There are several scripts that can be used to configure, administer and monitor your instance upgrade. These scripts can be accessed using the soa_upgrade_menu PL/SQL script.

To access the upgrade scripts menu:

Locate the /admin directory of the SOA home.

For example:

cd  <ORACLE_HOME>/soa/common/sql/soainfra/sql/oracle/upgrade/admin

Use SQL* Plus to access the _SOAINFRA schema using the schema owner name and password.

For example:
```
sqlplus dev_soainfra/password
```
where dev is the schema owner prefix you used when the SOAINFRA schema was created, and password is your schema password.
Note:

If you attempt to access the administration scripts using a user other than <prefix>_SOAINFRA, you will encounter the following error message:
```
ERROR at line 24:
ORA-06550: line 24, column 3:
PLS-00201: identifier 'CONTROL_MIGRATION.UPGRADE_STATUS_INFO' must be declared
```

Run the soa_upgrade_menu.sql script to see the upgrade administration options menu.

Option Number	Scripts Name	Use this option to...	Description
1	Report Upgrade Summary	View the overall status of the upgrade.	The report is divided into sub-sections and provides an overview of the overall upgrade and the current run. The `Report Upgrade Summary` shows the upgrade summary for METADATA, OPEN ECIDS (open instances) and ALL ECIDS (closed instances). The upgrade status is either COMPLETE or OUTSTANDING (still running). In addition, it describes the following: Last upgrade date for closed 11g instances The `Maximum Upgrade Date for Closed 11g Instances` section displays the closure date of the last upgraded flow. The upgrade starts with the most recently closed instances and continues until the oldest completed instance is upgraded. An instance flow that closed on January 1, 2014 would be upgraded before a flow that closed on December 1, 2013. A `Maximum Upgrade Date` of June 1, 2013 indicates that all closed instances up to June 1, 2013 have been upgraded and any instances that were closed before June 1, 2013 are still in the process of being upgrade. Upgrade error count The `UPGRADE ERROR COUNT` displays the number of errors that have occurred during the upgrade. You can use the `upgrade_error_log` file to determine the cause of the errors. For more information on handling upgrade errors, see Resolving Instance Upgrade Errors. Instance count since start of upgrade The `Overview Since Start of Upgrade` shows the start date and time of the upgrade, the total number of instances to be upgraded and the number of instances remaining. Current Run Statistics Upgrade data from the current upgrade run. Each run is numbered. In the sample report below, the data is from the first run (run:1). A designation of (run:2) would indicate that the upgrade was run for the second time and the statistics displayed are for second run. `START COUNT`: Details how many instances are outstanding as of the start of the RUN. For subsequent upgrade RUNs (run2, run3, etc.) the `START COUNT` total will detail what was remaining at the completion of the previous run. `REMAINING COUNT`: During the upgrade run a sum of "current instances that have not been processed" is collected every 5 minutes during the RUN. The "current instances that have not been processed" are then subtracted from the `START COUNT` to produce a `REMAINING COUNT.` `REMAINING COUNT`= `START COUNT` - "current instances that have not yet been processed" `PROCESSED COUNT`: `PROCESSED COUNT= START COUNT - REMAINING COUNT` The report data is shown below: ============================================= Report Upgrade Summary (Please wait for report to generate) ============================================= . .

2	Report upgrade database sessions (Running sessions).	Determine which jobs are still running. Do NOT use this information to manually kill the jobs.	The option will return running sessions data under 'Module', 'Inst', 'Sid' and 'Serial' columns. For example: ====================================================== Report Upgrade Database Sessions (Running) ====================================================== . Module Inst Sid Serial --- -- -- ---- SOAUPGRADECONTROLMAIN 1 122 16535 SOAUPGRADEDATA_0 1 228 14557 SOAUPGRADEDATA_1 1 64 46683 SOAUPGRADEDATA_2 1 180 621 SOAUPGRADEDATA_3 1 130 61577 SOAUPGRADESUBMITJOBS 1 172 66 Monitor job completion through the database scheduler job log. CAUTION: Do not use this information to stop the sessions. Use the administration script as described in Stopping Upgrade Sessions and Jobs.
3	Report upgrade database background jobs (Completed jobs).	Determine which jobs have completed the upgrade.	The database sessions that perform the instance upgrades are executed as database jobs. Once the jobs are complete, the status can be viewed with this option. The user is not expected to understand what each job does, only to ensure that the status shows success without any errors. The report displays the control job parameter values, the submitted upgrade job, current status of the job (submitted, waiting, running) and the job thread number (if applicable). For example: ====================================================== Report Upgrade Database Background Jobs (Completed) ====================================================== . . State of last 15 completed Jobs in descending order . Log_date Job_name Status ERROR ---- ---- --- ---- 21-FEB-2014 03:07:36 UPGRADE_SOA_METADATA_JOB SUCCEEDED 0
4	Report background control job parameters.	View the current background control job parameters.	This option will report the parameters that are passed to the control job which coordinates the instance upgrade. ====================================================== Report Backgrond Control Job Parameters ------------------------------------------------------ BATCH_SIZE : 10000 MAX_COUNT : 100000 JOB_MAX_RUNTIME : 240 DOP : 4 METADATA_JOB_COMPLETE : TRUE OPEN_ECIDS_COMPLETE : FALSE DATA_JOB_COMPLETE : FALSE CTL_MAX_RUNTIME : 1 FIRST_TIME : FALSE FIRST_CTL_MAX_RUNTIME : 0 FIRST_JOB_MAX_RUNTIME : 0 SQL_TRACE : FALSE METRICS : TRUE ASYNC : TRUE ----------------------- ENABLE : FALSE REPEAT INTERVAL : freq=daily; byhour=3; byminute=0; bysecond=0
5	Change background control job execution schedule.	Change the repeat interval time and duration of the background control job.	By default, the background control job interval will start at 3AM (local time) and run for 4 hours (240 minutes) every day until all of the closed instances have been upgraded (set in terms freq=daily; byhour=3; byminute=0; bysecond=0). If you want this job to run at a different time, use this option to change the repeat interval. Change Background Control Job Execution Schedule - Repeat Interval ================================================================== The repeat interval determines when the control procedure is executed by the database scheduler. Examples of repeat intervals can be found in the Oracle Database Administors Guide. Enter REPEAT INTERVAL: For more information, see Changing Background Control Job Execution Schedule (Option 5) NOTE: To change the duration of the run (default is 240 minutes), modify the `JOB_MAX_RUNTIME` using the Change Background Control Job Parameters (Option 7).
6	Enable/Disable background control job.	Enable or disable the background job.	By default, the Enable/Disable background control job is disabled (`ENABLE: FALSE`). Enter Y (Yes) to change the current setting. Note that disabling the control job will prevent the background control job from running at the specified repeat interval. The setting will appear in the Summary Report as `ENABLE: TRUE` or `FALSE`. Enter N (No) to retain the current setting. ENABLE/DISABLE CONTROL JOB SCHEDULE =================================== Disabling the Control Schedule will stop the Control job from executing at the specified Repeat Interval. Change ENABLE Y/N: For more information, see Enabling and Disabling Background Control Job (Option 6)
7	Change background control job parameters.	Change the BATCH_SIZE, MAX_COUNT, JOB_MAX _RUNTIME or DOP (degree of parallel (options 1-4). Do not change the Advanced Options (options 5-14) unless instructed to do so by Oracle Support to troubleshoot an upgrade.	For most upgrades, the default values for the background control job parameters are sufficient. However, if you need to make changes, review the parameter descriptions in Setting Control Job Parameters (Option 7). 1: Set BATCH_SIZE 2: Set MAX_COUNT 3: Set JOB_MAX_RUNTIME 4: Set DOP .

MAX_COUNT	100000	Determines the number of instances (ECIDs) that are fetched to upgrade before another MAX_COUNT worth of instances is fetched.
JOB_MAX_RUNTIME	240 minutes (4 hours)	This is the maximum number of minutes that a background control job will run.
DOP	4	The number of parallel execution servers associated with a single operation is known as the degree of parallelism (DOP). Parallel execution is designed to effectively use multiple CPUs. CAUTION: Changing the degree of parallel is an advanced option. Refer to your database administration documentation for more information on setting the appropriate degree of parallelism for your deployment.
SQL_TRACE	FALSE	NOTE: Setting `SQL_TRACE` to `TRUE` can be used to debug and troubleshoot, but it may require the DBA to grant "alter session" to the soainfra user as shown below: $ sqlplus / as sysdba SQL> grant alter session to <soainfra>;

Stopping Upgrade Sessions and Jobs

You can use the administration scripts to stop a running session or job.

Note:

If you stop a running upgrade job before it has completed, you will not be able to query the remaining data or view it using Enterprise Manager Console.

The background jobs upgrade the newest instances first, so you can see how far the upgrade has progressed by looking at the timestamp of the last upgraded instance in the Upgrade Summary Report (Option 1) under the Maximum Upgrade Date for Closed 11g instances section.

There are two ways to stop the upgrade of read-only instances:

Once the background database control job has started, use the Stop Upgrade Database Background Sessions and Job script (Option 8) to stop ALL of the upgrade sessions and jobs that are currently running. It can take a few minutes before all of the jobs have stopped.
```
Stop Upgrade Database Background Sessions/Jobs
==============================================
All upgrade sessions and jobs should stop but this may require 5 minutes to take affect.

There will be a one minute wait before this procedure returns.
Are you sure Y/N: Y
Enter for MENU
 
```
Use the Report Upgrade Database Sessions (Option 2) to verify that there are no jobs running.You can restart the upgrade job, if needed, by scheduling a job to run at a user-defined time. This is the preferred method.
Start a middle tier application, such as the SOA Managed Server.

Once a mid-tier application such as a managed server is started, the upgrade of closed instances is stopped automatically. You can use the administration scripts to schedule the upgrade job to run at another time.

Parent topic: Administering and Monitoring the Upgrade of SOA Instances

Restarting an Incomplete Upgrade

If the instance upgrade is stopped, it must be manually restarted using the administrations scripts as described below.

Enable the background control job using administration script option 6 - 'Enable/Disable background control job'.

See Enabling and Disabling Background Control Job (Option 6).
Schedule the background control job execution to run at specific time interval using administration script option 5 - 'Change background control job execution schedule'.

See Changing Background Control Job Execution Schedule (Option 5).
When the time interval specified in Step 2 is reached, the background control jobs starts. Monitor the upgrade status using the administration script option 1 'Report Upgrade Summary'.

See Option 1 in Table 9-1.
Once the upgrade is completed, log in to Oracle Enterprise Manager Fusion Middleware Control, expand SOA, click soa-infra (soa_server1) and verify that the Data Migration Completed link is displayed under SOA Runtime Health section.

See Verifying Data Migration is Complete.

Monitoring Upgrade Status with Fusion Middleware Control

In addition to the administration scripts, you can also use the Oracle Enterprise Manager Fusion Middleware Control Console to view the general status of the upgrade. The administration scripts will provide you with more administrative control of the upgrade jobs, but you can monitor the following with the Fusion Middleware Control Console:

Note:

If you need to perform advanced administration tasks for the upgrade, such as modifying the schedule or interval time of the upgrade, for example, you must use the administration scripts as described in Using the Upgrade Administration Scripts.

Managing an Incomplete (Stopped) Upgrade

You can use Fusion Middleware Control to manage an incomplete upgrade, which can occur in the following situations:

None of the open or closed instances are upgraded.
Some of the open instances have upgraded. For example, if you stop the background control job manually using administration script option 8 (Stop upgrade database background sessions and jobs) during the upgrade of open instances.
Only open instances have been upgraded.
Some or none of the closed instances have been upgraded.

Note:

If you start the SOA managed servers before the instance upgrade is complete, Fusion Middleware Control will show the upgrade status as Data Migration Not Complete and you will have to manually restart the upgrade as described in Restarting an Incomplete Upgrade.

If the upgrade is not yet complete, Fusion Middleware Control can provide the maximum creation date for all 11g instances that have not yet been upgraded. This is important because the maximum creation date can also help you determine why some instances might not be visible in the 12c Enterprise Manager Console. For example, if you notice that some older 11g closed instances are not be visible in the Fusion Middleware Control console, you can check the maximum creation date for all non-upgraded instances to help you determine if its because the upgrade has not reached those instances yet.

To verify the status of an incomplete (stopped) upgrade using Middleware Control do the following:

In the target navigation pane of Oracle Enterprise Manager Fusion Middleware Control, expand SOA, click soa-infra (soa_server1). In the SOA Runtime Health section of the screen you will see the current status of the upgrade. For an incomplete upgrade, the status will be Data Migration Not Complete. You can refresh this screen every 5 minutes.

Figure 9-7 SOA Runtime Health: Data Migration Not Complete

Description of "Figure 9-7 SOA Runtime Health: Data Migration Not Complete"

Click Data Migration Not Complete and the following message is displayed:

Figure 9-8 SOA Runtime Health: Migration Not Complete Status Message

Description of "Figure 9-8 SOA Runtime Health: Migration Not Complete Status Message"

Data Migration Status:

Active Instances: Shows the status of upgraded open instances. In the example above, the open instances have already been upgraded (status will be Completed).
Inactive Instances: Shows the status of upgraded closed instances. In the example above, closed instances older than July 9, 2013 have not yet been upgraded. The upgrade is performed newest to oldest. Any instances that have not yet been upgraded will not appear in any Fusion Middleware Control reports or views. You can refresh the report every 5 minutes.

Note:

For a detailed report of the running upgrade, run the Report Upgrade Summary script (Option 1) as described in Running the Administration Scripts.

Once all the closed instances are upgraded, the link will change to Data Migration Completed as shown in Figure 9-4.

Viewing Instances that Faulted During the Upgrade

The 11g instances that incur a fault and fail during the upgrade can be seen only at the composite level post-upgrade. These instances will not be displayed at the partition level.

To view these instances, navigate to the Flow Instances tab of the deployed composite as shown in Figure 9-9:

Viewing Instances Created Prior to Composite Redeployment

If a composite is redeployed with the same pre-upgrade revision, then you must navigate to the partition level (instead of composite level) to view these instances as shown in Figure 9-10.

Instances created after the upgrade, however, can be viewed in the 12c composite level.

Resolving Instance Upgrade Errors

If the upgrade fails or the UPGRADE ERROR COUNT section of the Report Upgrade Summary report (Option 1) shows that there were errors in the current run, you must resolve the errors before resubmitting the instances to upgrade.

The upgrade_error_log can be used to diagnose the error situation and may provide guidance on how to resolve the issue. For more information on resolving common upgrade errors, see Recovering From a Failed Upgrade.

The table below describes each of the errors and possible resolutions:

Error Type	Description	Error Message	Resolution
0	These errors were reported in the previous upgrade run. Type will be set to 0 after resetting the errored instances as described in Resetting Errored 11g instances (Option 9)).	Error message giving details about error occurred based on previous error type.	Correct the errors from the previous run and reset using Administrative Script.
1	Error occurred during the upgrade of instances.	The error message will have actual error thrown from the Upgrade script. It will also show a stack trace which will point out the line in the Upgrade PL/SQL script where the error has occurred.	Debugging the root cause can be done by looking at the actual error along with the trace to get the location of the error. ECID populated in the info column will be helpful in getting the data for failed instance.
2	Error occurred during upgrade of EDN error event store or Adapter rejected messages.	The error message will contain the string `upgrade_rejected_message/upgrade_edn_message` to determine which component it failed It will contain the reason for failure along with the id of the message which failed.	Debugging can be done by analyzing the actual reason of the error. To get the details of the adapter/edn message which has failed the id logged as part of ERROR_MSG can be used.
9	Error occurred during the upgrade of metadata.	It will have details of the `composite_dn` for which the metadata upgrade has failed It will have the actual error thrown from Upgrade script also with a stack trace which will point out the line in the Upgrade PL/SQL script where the error has occurred.	Debugging can be done by looking at the actual error along with the trace to get the location of the error. Info column will give the whole `composite_dn` for which the metadata upgrade has failed.
12	Generic error occurred during the data upgrade process and not pertaining to any single instance.	Info will only contain the string `migrate_soa` It will have the actual error thrown from Upgrade script also with a stack trace which will point out the line in the Upgrade PL/SQL script where the error has occurred.	This error type will be reported during upgrade run when the data upgrade as a whole fails and not necessarily pertaining to any particular instance. An example of this type of error may be the TEMP table space issue.

Restarting a Failed Upgrade

Once the errors have been resolved, use the following steps to restart the upgrade:

Fix the error condition(s) displayed in the upgrade_error_log.
Remove the error flags from the upgrade_error_log as described in Resetting Errored 11g instances (Option 9). This will allow the errored instances to be resubmitted in a subsequent run.
Enable the background control job as described in Enabling and Disabling Background Control Job (Option 6). You will have to trigger another upgrade run.
If necessary, change the repeat interval time and duration of the background control job as described in Changing Background Control Job Execution Schedule (Option 5).
Monitor the upgrade status using the Report Summary Upgrade script (Option 1). The UPGRADE ERROR COUNT section of the report should show 0 errors. If errors persist, resolve the issue and repeat these steps.
