Issue/Introduction
CA-JOBTRAC is capable of controlling the workload across multiple systems. This article is applicable for systems withshared DASD. You must start CA-Jobtrac on each system you would like the workload to be monitored. The following diagram is a sample of a multiple CA-JOBTRAC environment.

CA-Jobtrac in a Multiple System Environment
SYS1 is the primary CA-Jobtrac. Your primary system is where all event submission takes place. SYS2 and SYS3 will be your secondary monitoring systems. The monitoring systems do not submit any events. They monitor the events that were submitted by the primary system. You will need to define the primary and secondary monitoring systems in the JOBTRAnn member of the TRACPARM data set by using the keywords SYNCSYS1, SYNCSYS2,and SYNCSYS3. SYNCSYS1 defines the primary system. SYNCSYS2 and SYNCSYS3define the secondary monitoring systems. Each keyword points to the SMF system id of the appropriate system. All 3 systems will share all files including the TRACPARM data set. The following is a sample of the JOBTRAnn member of the TRACPARM data set.
You can also view the primary and secondary definitions by looking in the CA-JOBTRAC global options panel at the SYSID priority list. Here is a sample of the global options panel.
Once CA-JOBTRAC is started on the primary system you will see the following message in the JES log for CA-Jobtrac.
STC05657JOBTRAC- PRIMARY SUBMISSION SYSTEM (SYS1).

Once CA-Jobtrac is started on the secondary systems you will see the following message in the JES log for CA-Jobtrac.
STC01195JOBTRAC- AUTOMATION MONITOR SYSTEM (SYS2).
CA-Jobtrac gives you the ability to change the primary system on the fly. You can issue the modify command:
F STCNAME,ACTSYS=XXXX
STCNAME is you should replace with the CA-Jobtrac started task name.
XXXX is the SMF identification of the system you would like to make the primary.
For example, if SYS1 is currently the primary and you would like to make SYS3 the primary you would issue the command:
F STCNAME,ACTSYS=SYS3
You will get the following WTOR on your console:
*49 TRAC737W- VERIFY THAT THE PRIMARY JOBTRAC IS INACTIVE
AND REPLYTO CONTINUE (Y/N)
R 49,Y
JOBTRAC- PRIMARY SUBMISSION SYSTEM ASSIGNED.
TRAC1068IACTSYS=SYS1 command processing complete
You should reply yes and the primary will be switched.
THE BIG GOTCHA!!!!!
Changing the definitions of your SYNCSYS1 – SYNCSYS3 keywords and recycling ALL of the CA-Jobtrac’s, does not switch the primary system definition.
The SMF system identification defined in the JOBTRAnn member is stored in the CA-Jobtrac checkpoint data set. Recycling CA-Jobtrac has no affect on what is stored in the checkpoint data set. IN ORDER TO SWITCH THE PRIMARY SYSTEMS, YOU SHOULD USE THE MODIFY COMMAND MENTIONED ABOVE.
