Purging a Workgroup
To delete a user-defined workgroup from the current configuration, you
use the PURGEWG command. You can delete one workgroup, several
workgroups, or all of the user-defined workgroups on the system. You
cannot delete any of the system-defined workgroups.
Here is the syntax of the PURGEWG command:
PURGEWG [WORKGROUP=] {workgrpspec} {(workgrpspec [,workgrpspec]...)}
[{;CONFIRM }]
[[;ONERROR=] {CONTINUE}] [{;NOCONFIRM }] [{;NOSHOW}] [{;SHOWERRORS }]
[ {QUIT }] [{;CONFIRMALL}] [{;SHOW }] [{;NOSHOWERRORS}]
[{;SHOWERROR }] [{;PURGESCAN }]
[{;NOSHOWERROR}] [{;NOPURGESCAN}]
The options to the PURGEWG command allow you to determine what to do in
case there is an error, how much control you have over the purge
operation, and how much information you see.
To delete one workgroup
To delete one user-defined workgroup on the system, enter:
PURGEWG WORKGROUP=workgrpspec
For example, to delete a workgroup named Payroll_batch, enter:
PURGEWG WORKGROUP=Payroll_batch
Or you can enter:
PURGEWG Payroll_batch
To delete all user-defined workgroups
To delete all user-defined workgroups on the system, you can issue the
PURGEWG command and specify the @ wildcard character. Even though this
literally translates to "all workgroups", not just user-defined
workgroups, the Workload Manager will not purge any of the system-defined
workgroups.
For example, suppose you have 3 user-defined workgroups on your system
and, of course, the 5 system-defined workgroups. When you issue the
PURGEWG @ command, you'll see the following messages:
_____________________________________________________
| |
| |
| :PURGEWG @ |
| |
| 8 workgroups matched |
| Continue PURGEWG ? (YES/NO)y |
| 8 selected. 3 succeeded. 5 failed. |
| Operation failed on some files. (CIWARN 490) |
| |

To defer scanning a workgroup
When you purge a workgroup, the Workload Manager immediately scans all of
its member processes and moves them to other workgroups. This action is
called a purgescan. You can choose to defer the purgescan until a later
time with the NOPURGESCAN option of the PURGEWG command. Deferring a
purgescan is a good idea when you are deleting multiple workgroups.
Otherwise, the Workload Manager may place processes from the workgroup
you just purged into another workgroup that you plan to purge
subsequently.
For example, to purge the workgroup Payroll_batch and defer scanning,
enter:
PURGEWG Payroll_batch;NOPURGESCAN
Once you have issued the PURGEWG command with the NOPURGESCAN option, the
workgroup becomes "purge-pending". Purge-pending workgroups are those
which still have member processes, and they remain in a purge- pending
state until the member processes are moved via a purgescan, until you
explicitly reassign them to another workgroup, or until they die.
To request a purgescan of all purge-pending workgroups
To explicitly request that Workload Manager rescan all processes
belonging to purge pending workgroups, enter:
PURGEWG;PURGESCAN
