Overview of BMC Subsystem Optimizer for zEnterprise

BMC Subsystem Optimizer for zEnterprise (Subzero) products run in an IBM z/OS sysplex environment. Subzero redirects subsystem access requests that are issued by applications on one logical partition (LPAR) to subsystems that are running on a different LPAR.

Subzero replaces supported subsystem access routines, such as those that application programs running under the IBM CICS product use to access IBM DB2 or IBM IMS subsystems or communicate IBM MQ (fomerly called IBM WebSphere MQ) messages. Subzero also replaces supported subsystem access routines that MQ uses to communicate with DB2 and IMS subsystems. Subzero products include:

  • BMC Subsystem Optimizer for DB2
  • BMC Subsystem Optimizer for IMS
  • BMC Subsystem Optimizer for MQ

Note

In this document, the term Subzero refers to any BMC Subsystem Optimizer product. The term includes a qualifier (such as for DB2) only when the information is specific to that product.

The following topics provide background information that you need for configuring and using the product:
