ARMBARC—Archive log data sets

The archive log copy program, ARMBARC, enables you to make up to two additional copies of the original archive log data sets for transport to the recovery site.

When an archive log data set is in use, ARMBARC waits until the file is available. ARMBARC can also be used to identify image copy information for the Db2 special spaces that are registered on the log. You can use ARMBARC at the recovery site to move archive data from tape to disk. In addition, ARMBARC supports syntax for the PACLOG product.

Important

Image copy information for most table spaces in Db2 is registered in the SYSIBM.SYSCOPY table. However, several spaces have their image copies registered in the log. These spaces are DSNDB01.DBD01, DSNDB06.SYSCOPY, DSNDB01.SYSDBDXA, and DSNDB01.SYSUTILX. ARMBARC stores image copy registration information that is found in the log into the archive history file so that ARMBSRR can optimize recovery JCL for the catalog and directory.

ARMBARC checks the archive history file to identify archive log data sets that have not been processed, as well as those for which no recovery site copies have been made. It makes the requested number of copies for each log that has no recovery site copies and writes those copies to the media that you specify (tape or disk). BMC AMI Recovery Manager automatically catalogs the copies at the local site. Options enable you to limit the number of logs that BMC AMI Recovery Manager copies or processes.

The archive log history file data set name is found in BMC AMI Recovery Manager options. The data set is dynamically allocated. If the archive log history file is not found, BMC AMI Recovery Manager will create and initialize it.

Important

All original archive log data sets that are required to be processed by ARMBARC must be cataloged. BMC AMI Recovery Manager does not process uncataloged archive log data sets.

The ARMBARC program creates a set of three data sets for each archive log data set that is copied, as follows:

  • A copy of the Boot Strap Data Set (BSDS)
  • A copy of the archive log data set
  • A copy of the archive history file

Important

New users of BMC AMI Recovery Manager must run ARMBARC or use the sample member ARMHSTEX in the .SAMP data set to create the history file for each Db2 subsystem.
