Using System State Manager › Define Resource Management Modes for SSM

Define Resource Management Modes for SSM

You can set the mode for all SSM resources, all resources in a table, or per resource. The mode that you specify for the STATEMAN parameter causes SSM to use that mode to manage all of its tables and resources. For example, if you set STATEMAN=PASSIVE, all tables that are listed in the directory table and all the resources that are defined in those tables are monitored in PASSIVE mode.

Similarly, if you set STATEMAN=ACTIVE and you want to use INACTIVE mode for one table without affecting the other tables, you can do so by setting the TABLE_MODE value for that table to INACTIVE in the definition of the directory table of that table. You can also set the management mode for an individual resource by setting the MODE column in the definition of the resource table of that resource. In the hierarchy of mode values, the most restrictive mode always applies.

Some aspects of resource management mode are also affected by settings other than resource management mode. For example, the PREMODE and REFMODE columns of the resource tables affect prerequisite and subrequisite processing.

The mode SSM uses to monitor resources directly affects what values the CURRENT_STATE and DESIRED_STATE columns of your resource tables contain. If CA OPS/MVS becomes active, both the CURRENT_STATE and DESIRED_STATE columns for a resource set to the value in the table-relative UNKNOWN state for that resource as defined in the directory table. The same is true if SSM is running in INACTIVE mode and you change the mode to ACTIVE or PASSIVE, or if you set the monitoring mode for a specific table using the OPSSMTBL command.

To take full advantage of operating in PASSIVE or ACTIVE mode, you prime the DESIRED_STATE column. For an explanation of how to prime this column, see Setting the Desired State.

Follow these steps:

• Set the processing mode of a system, table, or resource using OPSVIEW option 4.11.1 (System State Manager Control) or option 4.11.2 (System State Manager Resource Control).

  You can also use the following methods:

• To set the SSM monitoring globally:

  Set the STATEMAN parameter by editing the CA OPS/MVS parameter file, by using OPSVIEW option 4.1.1, or by using the OPS/REXX OPSPRM function or the OPSPARM TSO command:

  xxx=OPSPRM('SET','STATEMAN','ACTIVE')
  OPSPARM SET(STATEMAN) VALUE(ACTIVE)
  

• To set the mode for a particular table

  Issue the OPSSMTBL command processor as follows:

  OPSSMTBL CHANGE(tablename) MODE(modevalue)
  

• To set the SSM management mode for an individual resource

  Use the MODE column in the resource table:

  OI STATESET table.name MODE(newmode)
  

MODE

The MODE column in a resource table can be used to set the resource management mode of an individual resource to a more restrictive level than the level set by the STATEMAN parameter or the value of the MODE column in the directory table; however, it cannot override a more restrictive general setting. For example, if the management mode of a table is set to ACTIVE and the STATEMAN parameter is set to PASSIVE, then setting the value of the MODE column to ACTIVE for a resource would result in an effective mode of PASSIVE. In the same situation, setting the value of the MODE column of a resource to INACTIVE would make the resource management mode of that resource INACTIVE.
