Diagnosing problems with your data store configuration
Find out how to diagnose problems that are caused by your data store configuration and possible solutions to these problems. The following problems depend on the database that you use with your data store configuration and the level of that database:
Procedure
- Examine this section if your messaging engine uses a Sybase database for its data store. When you create your Sybase server:
- Ensure that you create the database server with a page size of at least 4 KB.
- Ensure that you set the lock scheme property on your server to the value datarows. This avoids the possibility of a deadlock on the data store tables.
- Examine this section if your messaging engine uses an Informix database for its data store and the messaging engine is unable to access its data store. When you configure your messaging engine to use an Informix database, specify the schema name in lowercase letters. For a full description of the configuring procedure, see Configure a messaging engine data store to use a data source.
