Planning your logging environment
Use this topic to plan the number, size and placement of the logs, and log archives used by IBM® MQ.
Logs are used to:
- Write recovery information about persistent messages
- Record information about units of work using persistent messages
- Record information about changes to objects, such as define queue
- Backup CF structures
The IBM MQ logging environment is established using the system parameter macros to specify options, such as: whether to have single or dual active logs, what media to use for the archive log volumes, and how many log buffers to have.
These macros are described in Task 14: Create the bootstrap and log data sets and Task 17: Tailor your system parameter module.
Note: If you are using queue-sharing groups, ensure that you define the bootstrap and log data sets
with SHAREOPTIONS(2 3).
