Table 52: DBH-specific files

If the DBH-specific files are not to be created on the storage medium specified in the media catalog, the system administrator can override these specifications by setting up the files with the CREATE-FILE command before the DBH is started.

The prefix SESLK cn is replaced by SESLK cnst in the case of TA-LOG, WA-LOG and cursor files of a linked-in DBH in a single service task.
