Configuring PACLOG
Installing PACLOG on multiple Db2 subsystems
After the PACLOG compression services are installed on an OS/390 system, PACLOG can be activated on all Db2 subsystems for that OS/390 system by simply adding the new Db2 subsystems to the PACLOG control information and creating the history data set.
If you have the BMC AMI Recovery Manager for Db2 product, seeIntegratingfor instructions. Otherwise, edit the data set referred to by the ALM$OPTS DD statement by adding the new control variables HIST, BSDS1, TSTAMP, and PROD.SNLOAD. You must have OS/390 data set READ and WRITE authority to edit the control information member. Then, create a new history file that refers to the PACLOG.DBCNTL data set member ALMHIST for a sample job.
Sample ALM$OPTS file
The following example shows a PACLOG control information data set.
You can choose any valid OS/390 data set name for the history file during installation. However, the name must be unique for each subsystem. You cannot use the same data set for multiple subsystems.
The naming conventions are shown in the sample ensure a unique name for each subsystem.

PACLOG installation options
This section describes the PACLOG installation options and their default values.
Option | Description |
|---|---|
WORKUNIT=SYSALLDA | Specifies the default unit for work data sets dynamically allocated by PACLOG. You can specify another valid unit name during installation if you do not want to use the default, SYSALLDA. |
TSTAMP=YES | Specifies to PACLOG that the timestamp (if it exists) is to be copied into the data set name of archive log copies 3 and 4. If TSTAMP is set to YES, the prefix for ARCHIVE3 and ARCHIVE4 cannot be more than 17 characters. If TSTAMP is set to NO, the prefix can be up to 35 characters. For more information, seePREFIX prefix. |
HIST= dataSetName | Specifies the subsystem’s BMC Software archive history data set. For more information about the archive history file, seeBMC archive history file. |
BSDS1= dataSetName | Specifies the bootstrap data set file name. |
PROD.DSNLOAD= dataSetName | Specifies the production Db2 load library. |
