Title: IDCAMS BACKUP using SYNONYMLIST requires un-needed
Detailed
Problem Description: The IDCAMS BACKUP allows use
of a SNAPPED
Catalog using the SYNONYMLIST. The SOURCEVOLUMES must be available and accessible with READ/WRITE
capabilities even though the physical data is taken from the TARGETVOLUMES. The TARGETVOLUMES should only be indicated
for establishing the volume to volume relationship of the IDCAMS BACKUP.
Priority: (Select one: Urgent - High - Medium - Low) HIGH

Completion Date: 6 months
Requirement
Type: Function-
performance-reliability/availability/serviceability
Business
Justification: IDCAMS
SNAP does the instanteous backup of SourceVolumes to TargetVolumes. The SourceVolumes are irrelevant after the
SNAP has completed. During the IDCAMS
BACKUP using the SYNONYMLIST, the
SourceVolumes add unnecessary overhead within the locking mechanism on
the on the z/VSE system. The TargetVolumes
could be linked/attached to a separate
z/VM backup System for better Operation management.
Solution: Remove the requirement that during
a IDCAMS BACKUP with SYNONYMLIST that the SourceVolumes need to be
physically/logically available.
Impact: Aultman Hospital is a 24/7 full function hospital. The current batch cycle takes about 4 hours
with limited availablity for some functions.
The IDCAMS
SNAP and IDCAM BACKUP with SYNONYMLIST would cut the batch cycle by 1-2
hours. Files could be available
for real time processing in a shorter
amount of time. Patient Health
information would be available and revenue would be enhanced.
