◼ Sign on to IMS
Log on to IMS
Issue COPE transaction
Specify the desired Virtual System
When changing Virtual systems the application program libraries to be searched is displayed (STEPLIB)
Bring up application format
Enter application data and run the application
Application run same as in non-COPE Environment

COPE Support for IMS Tools
• Integration with Compuware Products
–Xpediter (TSO and Topaz)
–Abend-AID IMS
– File-AID IMS
–Compuware Xchange
• Other vendor products (ex. File-Manager)
–Will work with COPE, but must use the COPE database names
–We have an API for vendors

How Long Does It Take to Create COPE for IMS?
Installation Step Duration
Install COPE 1 day
Import Stage 1, DFSMDA, DBDs and PSBs 1 week
Define IMS JCL; generate Stage 1 and Stage 2 1 day
Load IMS and Db2 databases 1 – 3 weeks
Setup connections to CICS and MQ 1 day
Total 3 – 5 weeks

Benefits of IMS Virtualization with COPE
• Create virtual environments within one IMS physical system• For different phases of application development
• For different versions of IMS applications and databases
• Application developers and testers work independently in own IMS
• Increase number of IMS systems in a single LPAR
• Reduce the number of IMS system migrations
• Lower CPU resource utilization by eliminating IMS address spaces
• COPE is not a simulator, emulator or system replicator
