This space provides the same content as before, but the organization of the home page has changed. The content is now organized based on logical branches instead of legacy book titles. We hope that the new structure will help you quickly find the content that you need.

Command and syntax reference

This section illustrates command syntax and describes each command option.

The R+/CHANGE ACCUM product provides the following commands:

  • The OPTIONS command specifies options that are set at runtime for use with R+/CHANGE ACCUM. You can have more than one OPTIONS statement in a job, but a particular specification can be defined only one time. (See OPTIONS syntax.)

  • The ACCUM command specifies the groups of table spaces for which change accumulation is performed. You can use the ISPF interface to define groups. (See ACCUM syntax.)

  • The LOGSCAN command specifies table spaces and indexes for which log records and bytes are to be counted over a log range, without executing a sort, creating a change accumulation file, or updating the R+/CHANGE ACCUM repository. (See LOGSCAN syntax.)

  • The MODIFY ACCUM command specifies which repository records are to be deleted. This command is accepted by a different load module from the program that accepts the OPTIONS, ACCUM, and LOGSCAN commands. (See MODIFY ACCUM syntax.)

Subsequent sections provide the syntax for the OPTIONS, ACCUM, and LOGSCAN commands. For information about the MODIFY ACCUM command, see Deleting R+/CHANGE ACCUM recovery resources.
