Task 14: Create the bootstrap and log data sets

 

• Repeat this task for each WebSphere MQ queue manager

• You do not need to perform this task when migrating from a previous version.

Use the supplied program CSQJU003 to prepare the bootstrap data sets (BSDSs) and log data sets. You must run this job once for each WebSphere MQ queue manager you use. The sample JCL and Access Method Services (AMS) control statements to run CSQJU003 to create a single or dual logging environment are held in thlqual.SCSQPROC(CSQ4BSDS). Customize and run this job to create your BSDSs and logs and to preformat the logs.

The started task procedure, CSQ4MSTR, described in Task 6: Create procedures for the WebSphere MQ queue manager, refers to BSDSs in statements of the form:

//BSDS1     DD DSN=++HLQ++.BSDS01,DISP=SHR
//BSDS2     DD DSN=++HLQ++.BSDS02,DISP=SHR

The log data sets are referred to by the BSDSs.

Notes:

1. The BLKSIZE must be specified on the SYSPRINT DD statement in the CSQTLOG step. The BLKSIZE must be 629.

2. To help identify bootstrap data sets and log data sets from different queue managers, include the subsystem name in the high level qualifier of these data sets.

3. If you are using queue-sharing groups, define the bootstrap and log data sets with SHAREOPTIONS(2 3).

See WebSphere MQ for z/OS Concepts and Planning Guide for information about planning bootstrap and log data sets and their sizes.
