Software allows copying of VSAM files with full integrity.June 10, 2004 - CICS VSAM Copy for z/OS® V1.1 permits creation of point-in-time copies of VSAM files concurrent with business-critical online processing. Copies are made without interrupting online user, who can continue to update VSAM data sets being copied. Resulting copy does not contain any in-flight or ongoing units of work and therefore does not require further processing before it can be used. Utility can also produce offline copies, without interaction with CICS.

IBM CICS VSAM Copy for z/OS Allows Rapid Copying of One or More VSAM Files with Full Integrity
Overview
This new utility is designed for creating copies of VSAM data sets that are used by CICS® applications. CICS VSAM Copy for z/OS® V1.1 allows the creation of “point-in-time” copies of VSAM files concurrent with business-critical online processing. Copies are made without interrupting the online user, who can continue to update the VSAM data sets being copied. The online CICS user is completely unaware that the copy takes place. There is no discernible effect on transaction response time in typical user situations.
Uniquely, CICS VSAM Copy creates a copy of a VSAM file, with full data integrity and consistency, without requiring activity on the VSAM data set to cease before starting the copy. The resulting copy does not contain any in-flight or ongoing units of work (UOWs) and therefore does not require any further processing before it can be used. The copy produced has the “point-in-time” consistency of a copy produced by an offline batch utility, without the disadvantage of application down time for batch processing.
Although designed to produce online copies of CICS files, the utility can also produce offline copies, without interaction with CICS.
Key prerequisites
• CICS Transaction Server for OS/390®, V1.3 (5655-147), or later
or
• CICS Transaction Server for z/OS, V2 (5697-E93), or later

At a glance
CICS VSAM Copy allows the creation of point-in-time copies of
VSAM files concurrent with business-critical online processing
activity. The resulting copy is identical in format to one created by an IDCAMS REPRO request but the copy process is more efficient.
• Allows copies to be made any time by an authorized user.
• Provides automatic registration of all VSAM data sets in all
participating CICS regions. The requester does not need to
know which CICS region owns the data set to be copied.
• Removes the affect on copying of control interval splits, control area splits, new extents, CICS task abends, or the backout of inflight or continuous units of work (UOW).
• Works with data sets distributed over multiple volumes
supporting all the VSAM data sets currently supported by CICS Transaction Server (CICS TS) except those listed in the Description section.
