Usage notes

  1. Either USER or GROUP must be specified.
  2. USER and GROUP are mutually exclusive.
  3. For an explanation of wildcard pattern matching, see Wildcard pattern matching.
  4. If you have multiple DEFDSPS commands, the order of the commands is important; each occurrence does not override the previous command. In the following example, the second command does not override the first command:
    DEFDSPS USER USER1 SIZE 2M
    DEFDSPS USER USER* SIZE 3M
    DEFDSPS USER * SIZE 1M
    In this example, USER1's console has a 2M data space, the consoles of all other user IDs starting with USER have a 3M data space, and all other consoles have a 1M data space.
  5. The processing of a DEFDSPS command does not allocate a data space. A data space is allocated when the initial input from a monitored user’s console is received by Operations Manager.
  6. The maximum number of data spaces and the maximum amount of storage for all data spaces allocated by Operations Manager is limited by the CP directory entry for the user ID running GOMMAIN, which is OPMGRM1 by default. The CP directory’s XCONFIG ADDRSPACE statement controls the maximum number of data spaces and the maximum amount of storage for all data spaces. If a large number of data spaces are expected to exceed 16MB in size, examine the CP directory XCONFIG ADDRSPACE statement and adjust the TOTSIZE parameter as needed.
