| |
| Command: MODIFY Supported MVS Levels: SP1|XA|ESA |
| |
| Overview: The MODIFY command is used to change the existing parameters of |
| a job, TSO/TCAM, TSO/VTAM and an external writer. |
| |
| Additionally with MVS/XA and above, the modify command may also |
| be used to build a new LLA directory, display CATALOG address |
| space information, or request a specified service from the |
| CATALOG address space. |
| |
| Under MVS/ESAv4 you may also modify the DLF parameters and/or |
| processing modes and request specified services of OAM. |
| |
| With MVS/ESA version 5, you may modify the Network File System |
| server (MVSNFS) and the workload management mode. |

| Examples: The example below will modify the TCAM procedure TCAMX |
| in order to stop TSO/TCAM time-sharing: |
| |
| MODIFY TCAMX,TS=STOP or F TCAMX,TS=STOP |
| |
| The example below will modify the TSO/VTAM proc TCAS |
| in order to reduce the number of concurrent users to 1: |
| |
| F TCAS,USERMAX=1 |
| |
| The example below will modify all TSO/VTAM procs that start |
| with TCA to reduce the number of concurrent users |
| to Ø: |
| |
| F TCA*,USERMAX=Ø |
| |
| The example below will stop the writer 36Ø before it |
| processes each new data set: |
| |
| F 36Ø,PAUSE=DATASET |
| |
| The example below will refresh the LLA: |
| |
| F LLA,REFRESH |
| |
| The example below will terminate the CATALOG address |
| space which is suspected of being in an ENQ lockout |
| or wait: |
| |
| F CATALOG,ABEND |
| |
| The example below will free all catalog address space |
| private storage associated with the catalog named |
| CATALOG.ICF.GZONE.VSMPGZ1: |
| |
| F CATALOG,CLOSE(CATALOG.ICF.GZONE.VSMPGZ1) |
| |
| The example below will restart the catalog address space |
| in a new address space, possibly hoping to save an IPL |
| due to a catalog-caused system failure: |
| |
| F CATALOG,RESTART |
| |
| The example below will stop OAM and OSMC, but will allow |
| OAM to continue to process DISPLAY commands: |
| |
| F OAM,STOP,OAM |
| |
| The example below will set goal mode to compatibility mode: |
| |
| F WLM,MODE=COMPAT |
