CSL administration

The tasks associated with administering a CSL are typically performed by the system administrator or system operator.

Using the z/OS Automatic Restart Manager with the CSL
A CSL address space (ODBM, OM, RM, SCI), if requested, can register with the z/OS® Automatic Restart Manager (ARM). The ARM is a z/OS recovery function that can improve the availability of started tasks. When a task fails or the system on which it is running fails, the ARM can restart the task without operator intervention.
Administering global online change
This topic covers enabling and disabling global online change for an IMSplex. This topic also covers maintaining an IMSplex with mixed online change scope.
Administering automatic RECON loss notification
RECON loss notification is automatic after the IMSplex name for the RECON is specified.
Monitoring an IMSplex
Monitoring the individual IMS systems in an IMSplex with CSL is not different from monitoring a standalone IMS system in any other environment. Monitoring the IMSplex as a whole, however, is different than monitoring an individual IMS system.
Diagnosing IMSplex problems
Each of the Common Service Layer address spaces, OM, RM, and SCI, produces SDUMPs for internal errors. You can find the CSL dumps in the SYS1.DUMP data sets.
