HIGH - Best suited for backups over slower networks where the limiting factor is network speed

ZDM_SHARD_ID

ZDM_SHARD_ID is used to ensure that a migration job is running or is being resumed in the correct intended pod.

In a scenario where Zero Downtime Migration is scaled out to service multiple simultaneous migrations, each ZDM server has its own metadata store, which means that the same migration job ID values could be repeated across multiple ZDM servers.

To avoid job ID conflicts which could cause the incorrect job to be resumed on the incorrect ZDM server, the ZDM_SHARD_ID for each job will be configured contain the ZDM host name to which the migration job is being sent. This value will be seeded by E2E during RSP creation.

The value of ZDM_SHARD_ID and the other RSP tokens will be used by ZDM to confirm that the job metadata matches the RSP file values for the source and target database properties to ensure the correct job ID and ZDM server are resumed.

If the value from ZDM_SHARD_ID in the response file is set, and it does not match the current host name, the following exception is thrown:

PRGZ-#### : Specified shard ID zdm_host_name_a does not match with current ZDM host zdm_host_name_b.

in which den01gl is the value read from the response file, and den01glt is the current pod's host name

Property Description

Syntax

ZDM_SHARD_ID = zdm_host_name

Default value

No default value

By default, ZDM will not consider the host name before starting or resuming a job.

Range of values

ZDM_SHARD_ID accepts the host name of the pod in which the current job will be run or resumed. It accepts host name or fully qualified domain name.

The ZDM_SHARD_ID verification is case insensitive

ZDM_SKIP_DG_CONFIG_CLEANUP

ZDM_SKIP_DG_CONFIG_CLEANUP indicates whether Zero Downtime Migration should clean up the Oracle Data Guard configuration from the source and target databases at the end of the migration when using online physical migration.

Property Description

Range of values

TRUE - Do not clean up the Oracle Data Guard configuration.

FALSE - Clean up the Oracle Data Guard configuration.

ZDM_SRC_TNS_ADMIN

ZDM_SRC_TNS_ADMIN specifies the custom location for TNS_ADMIN on the source database server when there is no Oracle Grid Infrastructure. If a Grid Infrastructure exists, then the TNS_ADMIN property must be set in the CRS resource attribute environment of the database resource.

Range of values

TRUE - Use the existing undo tablespace size.

FALSE - Do not use the existing undo tablespace size.
