XCOMUTIL History File Utility

XCOMUTIL is the CA XCOM Data Transport utility that maintains the CA XCOM Data Transport history file. This utility performs two functions on the history file. Run the purge utility periodically to prevent a history file full condition. The utility has been designed as an offline utility because VSAM is inefficient at reclaiming space when records are randomly deleted from a VSAM cluster. Run the migration utility to migrate an existing history file to work with the 11.6 release of CA XCOM Data Transport.

To reclaim the space (Purge)

1. Copy the history file to a sequential file.
2. Run XCOMUTIL against this sequential file to purge a specified range of records and create a new sequential file.
3. Delete the existing history file and create a new one.
4. Copy the new sequential file to the history file.

To convert an existing file (Migration)

1. Copy the history file to a sequential file.
2. Run XCOMUTIL against this sequential file to purge a specified range of records and create a new sequential file.
3. Create a new history file, deleting an existing one from a previous migration run.
4. Copy the new sequential file to the new history file.

Note: The CA XCOM Data Transport server cannot be executing when XCOMUTIL is used.
