Controlling z/OS PAS operation
MODIFY commands
Using a MODIFY command, you can change some of the z/OS PAS parameters without having to recycle the PAS or disrupt Extractor recording.
The following parameters can be used in a MODIFY command:
- CPM
- DC
- IPM
- R
- STDC
- USEZIIP
- XDS
The following table shows examples of valid MODIFY commands that can be used to control the z/OS PAS and the Extractor:
If you enter this value | z/OS PAS performs this action |
|---|---|
F MVSPAS,CPM=07 | Invokes CPM monitoring mode with control statement member CMFCPM07 when the PAS is initialized with CMDID=> |
F MVSPAS,IPM=XY | Invokes IPM monitoring mode with control statement member CMFIPMXY when the PAS was initialized with CMDID=> |
F MVSPAS,CPM=STOP | Stops CPM monitoring mode The z/OS PAS is also stopped, unless IPM monitoring mode is active. If DC=START was specified and IPM mode is active, the data collectors switch to DC=IPM. If DC=CPM was specified, the data collectors are stopped, regardless of the status of IPM mode. |
F MVSPAS,IPM=STOP | Stops IPM monitoring mode CPM monitoring mode remains active. If DC=START was specified, the data collectors switch to DC=CPM. If DC=IPM was specified, the data collectors are stopped. |
F MVSPAS,DC=STOP | Stops the data collectors BMC AMI Ops Monitor for CMF and BMC AMI Ops Monitor for z/OS are unavailable. For BMC AMI Ops Monitor for CMF, the samplers for the PGDDLAY and CFDATA control statements, if defined, suspend their sampling functions. |
F MVSPAS,DC=START | Invokes the data collectors BMC AMI Ops Monitor for CMF and BMC AMI Ops Monitor for z/OS are initialized. For BMC AMI Ops Monitor for CMF, the samplers for the PGDDLAY and CFDATA control statements, if defined, begin or resume their sampling functions. |
F MVSPAS,DC=STATUS | Produces a status display of the z/OS PAS data collectors on the console |
F MVSPAS,STDC=START | Starts short-term data collection by using BBPARM member BBDTST00 Short-term data collection is introduced in BMC AMI Ops Monitor for z/OS version 3.0.00 and BMC AMI Ops Monitor for CMF version 5.8.00. |
F MVSPAS,STDC=15 | Starts short-term data collection by using BBPARM member BBDTST15 |
F MVSPAS,STDC=STOP | Stops short-term data collection |
F MVSPAS,XDS=00 | Starts (or restarts) XDS by using BBPARM member CMFXDS00 |
F MVSPAS,USEZIIP=N | CPU processing that is eligible to be offloaded to zIIPS is now execute on standard CPs |
For BMC AMI Ops Monitor for z/OS, the R= sysprog parameter provides the ability to invoke SYSPROG services from the system console. The sysprog value includes the name of the service and any parameters that are required by the service. If the CMDID= symbol parameter is also defined, you can invoke the SYSPROG services from the system console as follows:
symbolsymbolsysprog
- symbol is a previously defined CMDID character.
- sysprog is a SYSPROG service name.
For example, if CMDID=# is defined in the z/OS PAS started task procedure, you can invoke the SYSPROG INFO service by entering ##INFO from the system console. One # symbol replaces the F MVSPAS value and the other # symbol replaces the R parameter.
