The agent joblog and TWSASPOOLS environment variable

About this task

By default, all information about the running of jobs is stored in the agent joblog. Most of this information usually consists of spool files. To select the spool file types that you want included in the agent joblog, use the TWSASPOOLS system variable, which works at IBM i agent level for any job to be submitted.

The TWSASPOOLS system variable forces the IBM i agent to either ignore all spool files or include one or more of them.

On the IBM i agent, create a new system level environment variable named TWSASPOOLS and set it to a list of the spool file types that are to be included. The list must begin with the SPOOLS: token.

For example, to force the IBM i agent to ignore all spool files, create the TWSASPOOLS variable as follows. 
ADDENVVAR ENVVAR(TWSASPOOLS) VALUE(SPOOLS:) LEVEL(*SYS)
where the list after the SPOOL: token is empty. In this case, any agent joblog report for the IBM i agent is limited to the activity report that the Agent Monitor produces to trace its submission and monitoring action, and to the IBM i joblog of the Agent Monitor, which is always added at the end of the agent joblog.
To allow the IBM i agent to include only the QPRINT and the QPJOBLOG spool file types, that is, any spool files produced by printf instructions inside any ILE-C program and any produced joblog, create the TWSASPOOLS as follows: 
ADDENVVAR ENVVAR(TWSASPOOLS) VALUE(’SPOOLS: QPRINT QPJOBLOG’) LEVEL(*SYS)
If the TWSASPOOLS variable already exists, change it as follows:
CHGENVVAR ENVVAR(TWSASPOOLS) VALUE(’SPOOLS: QPRINT QPJOBLOG’) LEVEL(*SYS)

If any VALUE parameter is set to an incorrect string, the IBM i agent ignores the TWSASPOOLS environment variable option. You can create and change the TWSASPOOLS environment variable while with the IBM i agent active, but no workload activity must be running.
