Event Processor Configuration Settings

With a Transaction Server instance selected, the following shows the typical values for Event Processor Configuration Settings:

Below are the settings:

• Sequencing Behavior

  This setting describes how the event sequencing occurs during Transaction Server processing.

  Event sequencing behavior values are:

  • AnySequence

    Events can be delivered in any sequence.

  • ByEventType

    Events are guaranteed to be delivered in sequence by event type.

  • ByUserSession

    Events are guaranteed to be delivered in sequence by originating user session.

  • GlobalFIFO

    Events are guaranteed to be delivered in sequence by their original generation sequence. This option does not permit concurrent processing and may impact performance. When this option is selected the Processing Concurrency value is ignored.

• Processing Concurrency

  This setting describes the number of concurrent event processing threads to run. Maximum of 4 concurrent threads can run enhancing the Transaction Server processing performance.

• Trigger Listener Delay

  This setting specifies the time, in milliseconds, between timer checks of the database for events waiting to be processed. A negative value will disable the timer.

• Max Transfer Session Size

  This setting specifies the maximum number of events to transfer in one transfer session (that is, one result set from the database).

• Initial Context Factory

  The InitialContextFactory for the JNDI service of the event server. This value is set as per the transaction server environment.

• Provider URL

  The Provider URL for the JNDI service of the event server. This value is automatically set as per the transaction server environment.

• Event Transfer Transaction Isolation

  The transaction isolation level to be used by the transfer agent when reading committed events from the database.

  Suggested values based on database server type hosting the F90710 table are shown in the following table:

  Server Type	Isolation Level
  AS/400	serializable
  Oracle	serializable
  SQL Server	serializable
  DB2 for Linux, Windows, and UNIX	serializable

• Event Client Session Check Interval

  This configuration is to check the frequency to check for an expired session.

• Event Client session Timeout

  This configuration is to check how long a session can be idle before it is timed out.

• App Server JDNI User

• App Server JDNI Password
