  • CDMSLIB
    Varies the CDMSLIB load library.
  • V
    nnnn
    Varies the specified load library.
  • ONline
    Varies the specified load library online.
  • OFFline
    Varies the specified load library offline.
Usage
Offline Load Libraries and Program Usage
When you vary a load library offline, the following program considerations apply:
  • You cannot search for programs in an offline load library
  • A request to load a program from an offline load library fails
  • A new copy request for a program from an offline load library is delayed until the library is varied online
The command can be used, for example, to prevent the system from attempting to load a program from a load library while a library maintenance function, such as a condense operation, is being performed.
Name of the Load Library
A load library is identified in a DCMT VARY LOADLIB command by a ddname/linkname specified for the library in a DC/UCF startup JCL. Issue a DCMT DISPLAY LOADLIB command for a list of valid names.
The following sample DCMT VARY LOADLIB command varies load library V0014 offline:
dcmt v loa v0014 off
Example
DCMT VARY LOADLIB Vnnnn ONLINE
      VARY LOADLIB V0014 ONLINE IDMS DC277002 V105 USER:*** LOADLIB V0014 VARIED ONLINE
