Full Directory Load

To perform a full load of the Directory, perform an INIT prior to the load. The INIT function can occur in a separate execution of DBUTLTY immediately preceding the LOAD or in a step preceding the step specifying the LOAD.

Without the Simplify option, verify that the CXX is not open to a MUF or any DBUTLTY function. With Simplify mode, there are edits to help ensure the MUF is not enabled and that the CXX is not in use elsewhere. Also with Simplify, the function either must run as the first function in the step needing the CXX or must follow a function that ensures the CXX was opened with the needed protection. That includes all functions that run only with MUF not enabled or after a function of ‘SET OPTION1=MUF_NOT_ENABLED’.

CA Datacom/DB restores all backup information during the LOAD with the following changes.

• CA Datacom/DB preserves the Directory name as established during the INIT. It ignores the name from the backup.
• The Simplify setting is preserved from the current Directory but ignored from the backup.
• CA Datacom/DB increments the run number from the backup by 10,000 and places that number in the initialized Directory. This ensures that the run unit number is not identical with that of the previous backup.

  If the 10,000 increment does not ensure that numbers do not repeat, back up the newly loaded Directory, initialize and reload the Directory to increment the run unit number by another 10,000.

• During the full load, CA Datacom/DB loads the information in the currently logical location in the Directory data set, not necessarily where it previously existed.

  Because of this movement, the Directory must not be open for processing. If the Directory is open for processing and CA Datacom/DB attempts to access the Directory, problems such as errors 13(126), 13(04), or 04(47) can occur.

• The update and read-only user counts are zeroed during the LOAD.
• The BACKUP and LOAD sequence can be used to move the Directory or to increase the Directory size. The Directory (CXX) can be moved to a new device with the BACKUP and LOAD functions.
