Policy Items for Sysplex Groups

You define a sysplex group when creating a new group object by specifying sysplex in the Group Type field of the Define New Entry panel.

There are certain restrictions for sysplex groups:

A system can be linked to only one sysplex group. The same system can be linked to other standard groups. This applies if the system is linked directly to the system group, or indirectly through a subgroup.
A subgroup may be linked to only one sysplex group.

Figure 1 is an example of the Policy Selection panel for Sysplex groups.

The policy items for sysplex groups are the same as those for standard groups with the following additions:

SYSPLEX

This policy item allows you to describe certain resources associated with the sysplex. For more information, see SYSPLEX Policy Item.

APPLICATION GROUPS

This policy item displays a list of all Sysplex Application Groups, indicating which application groups are selected for this sysplex. For more information, see ApplicationGroup Entry Type.

SYSPLEX DEFAULTS

This policy item displays a list of all Sysplex Defaults, indicating which sysplex defaults are selected for this sysplex. For more information, see Sysplex Defaults Entry Type.

DOMAINS

This policy item displays a list of all Remote Domains, indicating which remote domains are selected for this sysplex. For more information, see Remote Domains Entry Type.

LOCAL PAGE DATA SET

With this policy item you can predefine local page data sets that are used in recovery situations to prevent auxiliary storage shortage outages. For more information, see LOCAL PAGE DATA SET Policy Item.

JOB DEFINITIONS

With this policy item you can define the jobs that can or cannot be canceled (KEEP/CANCEL), in case the job is responsible for the shortage condition. For more information, see JOB DEFINITIONS Policy Item.

JOB/ASID DEFINITIONS

With this policy item you can define the jobs and address space IDs that can or cannot be canceled. You can specify KEEP if the job must not be canceled, DUMP to dump the job after the wait time has expired, or NODUMP to suppress the dump before the job is canceled.

For more information, see JOB/ASID DEFINITIONS Policy Item.

COMMAND DEFINITIONS

With this policy item you can define which commands you want to monitor and define a maximum time that a command can be blocked by a job or another command before recovery action takes place.

You can also specify an action (KEEP, DUMP or NODUMP) to be taken against this command if it is found to be blocking other commands from executing.

For more information, see COMMAND DEFINITIONS Policy Item.

COMMAND FLOODING

With this policy item you can define individually the interval time for snapshot processing for each command class. When message IEE806A triggers the recovery, the first snapshot is taken after the interval has expired.

For more information, see COMMAND FLOODING Policy Item.

RESOURCE DEFINITIONS

With this policy item you can define DUMP and other miscellaneous recovery options, including the message delay time for message ING920I (issued when option KEEP is specified), and IEADMCxx symbols.

For more information, see RESOURCE DEFINITIONS Policy Item.

RECOVERY OPTIONS

With this policy item you can define DUMP and other miscellaneous recovery options including message delay time for message ING920I (issued when option KEEP is specified), and IEADMCxx symbols.

For more information, see RECOVERY OPTIONS Policy Item.
