Q replication performance considerations

Now let's move on to look at some Q replication performance considerations. Our Q replication environment is made up of four components:

  • The DB2 database layer comprising the source and target databases

  • WebSphere MQ

  • Q Capture

  • Q Apply

Let's look at tuning each of these components.

The DB2 database layer

The DB2 source or target databases: The tuning that should be performed for the DB2 databases is normal tuning that we would do for any database. The only point to bear in mind is that the amount of DB2 log space required may increase due to DATA CAPTURE CHANGES being set. There are no other special considerations if the databases are involved in Q replication.

We may need to run RUNSTATS and REORGS on the replication control tables—these tables should be treated as any other application table.

The WebSphere MQ layer

We have mentioned the MAXDEPTH parameter for queues (Refer to the MQ Queue management—To define a Local Queue section of Chapter 4), and if we increase...
