Building and Rebuilding Directories

You build a directory at CA ACF2 initialization, you rebuild a directory after making changes to a rule set.

To build a globally resident directory at CA ACF2 initialization, you must specify a GSO INFODIR record. CA ACF2 Option for DB2 also loads copies of the rule sets at this time, if you specify them as resident.

You must rebuild a directory after you change a $KEY, $TYPE, or $SYSID because these control statements identify parts of the infostorage record key that are kept in directories. To rebuild a directory after you change a rule set, you must issue an operator command for the changes to take effect. You can dynamically rebuild globally resident CA ACF2 Option for DB2 rule directories with the following command:

F ACF2,REBUILD(typecode),CLASS(D)

The typecode represents the type of DB2 resource that the rule set protects. This command also reloads the associated rule sets that are kept in global storage. If you do not issue this command, the directories and rules are made resident the next time you IPL your z/OS system or stop and start CA ACF2.

You can clear rule sets that are locally resident with the SET NORULES subcommand. This subcommand clears the currently held, locally resident rule sets that were collected on a demand basis from the address space and permits more rule sets to be collected. You can issue this command as follows:

SET NORULES[(jobname)|ALL)]

The jobname value is the job name, the logonid of the DB2 subsystem, or the started task name. If you specify ALL, you will reset all locally resident rules for all CA ACF2 address spaces. An operator can also issue the F ACF2,SETNORUL(ALL) command to clear all users' address spaces of locally resident rules.

For more information about these commands, see the “The ACF Command,” and “Console Operator Commands” chapters in the CA ACF2 Administrator Guide.
