Product compatibility matrix

Db2 support

This version of BMC AMI Recover supports all IBM-supported versions of Db2.

System requirements

This version of BMC AMI Recover supports all IBM-supported versions of z/OS.

IDCAMS and DSNUTILB must be available in the system LPA, LINKLIST, JOBLIB, or STEPLIB.

zIIPs

BMC AMI Recover ascertains if the system has IBM z Integrated Information Processors (zIIPs). If it does, BMC AMI Recover offloads as much processing as possible to zIIP processors.

You can disable the use of zIIP processors by specifying OPTIONS ZIIP DISABLED.

Setting the MEMLIMIT parameter

The following products and components require above-the-bar memory and might abend if sufficient memory is not available:

• ALTER

• BMCSORT

• Catalog Manager

• Change Manager

• CHECK PLUS

• BMC AMI Copy

• DASD MANAGER PLUS

• High-speed Apply Engine

• LOADPLUS

• Log Master

• BMC AMI Recover

• BMC AMI Recovery Manager

• REORG PLUS

• UNLOAD PLUS

For most jobs, we recommend a value of at least 2 GB for the MEMLIMIT parameter. However, if you are operating on LOB or XML data, we recommend a value of at least 32 GB.

This value is set in member SMFPRMxx in SYS1.PARMLIB. Use any of the following methods if you need to override the default value:

• Specify the MEMLIMIT parameter in the JCL.

• Specify REGION=0M in the JCL.

• Use the SMF IEFUSI exit.

Software requirements

This version of BMC AMI Recover has the following requirements for additional IBM or BMC:

• You must have a minimum of version 12.1.00 of the BMC Db2 Solution Common Code (SCC) installed.

• If you want to offload eligible processing to a zIIP, you must have installed either XBM or SUF.

  If you use the XBMID option to specify a particular XBM subsystem, that subsystem must be at this maintenance level. If you do not specify a particular XBM subsystem and ZIIP ENABLED is in effect, BMC AMI Recover searches for an XBM subsystem at this level.

• To use any features that invoke DSNUTILB, you must have installed the IBM Db2 RECOVER utility.

  Important

  If BMC AMI Recover invokes DSNUTILB, the call displays in the AFRPLAN and AFRPRINT output files, and DSNUTILB messages display in the AFRPRnnn output files.
