Setting tuning properties of a messaging engine

Use this task to set the tuning properties for a messaging engine.

About this task
You can set the following properties to improve the performance of a messaging engine:
Name Value
sib.processor.blockedRetryTimeout The messaging engine custom property sib.processor.blockedRetryTimeout tells the application server how long to wait before re-delivering a message to an MDB, if and only if the exception destination property is set to None and the configured number of maximum failed deliveries has been reached.

The default value is 5000 milliseconds, which equates to 5 seconds. Any messages that are rolled back after the maximum failed deliveries limit will therefore remain on the original destination for 5 seconds before they are re-delivered to an MDB.

sib.trm.retry The messaging engine to messaging engine connection retry interval in seconds. The retry interval is the time delay left between attempts to contact neighboring messaging engines with which communications that exist. The default retry interval is 30 seconds.

To set the tuning properties for a messaging engine, use the administrative console to complete the following steps:

Procedure

  1. In the navigation pane, click Service integration > Buses > [Content Pane] bus_name > [Topology] Messaging engines > engine_name > [Additional Properties] Custom properties.
  2. Type the name of the property that you want to set.
  3. Type the value that you want to set for that property.
  4. Click OK.
  5. Save your changes to the master configuration.
  6. Restart the messaging engine for the changes to take effect.
