ULOGDSN
Specifies whether the user can override the name pattern that is specified in the LOGDSN parameter.
Y
The user can override the LOGDSN parameter.
N
The user cannot override the LOGDSN parameter.

If you specify ULOGDSN=N:

  • The IMS log Data set name pattern field on the DLI Mode Data Sets 2 panel is protected.
  • LOGDSN= statements in the HFMIMSIN input of batch jobs are ignored.
  • No LOGDSN= statements are included in the JCL generated by ZDT/IMS dialogs.

This parameter is optional. If it is not specified on the HFM1POPI macro statement, ZDT/IMS uses either the value that is specified on the HFM1POPD macro statement (if specified on that statement), or Y (otherwise).
