Product	Address space	WLM Service Class setting
MainView Transaction Analyzer	MainView Transaction Analyzer PAS	WLM Service Class SYSSTC
MainView VistaPoint	BBI-SS PAS (for CICS, Db2, DBCTL, and IMS workloads)	The same WLM Service Class or a WLM Service Class with higher goals than any of the target subsystems that the PAS manages If the WLM Service Class assigned has a goal lower than the WLM Service Class assigned to the target subsystems, loss of data or excessive storage usage could occur.
MainView VistaPoint	z/OS PAS (for IBM z/OS MVS workloads)	A WLM Service Class with higher goals than any of the CICS, DB2, DBCTL, or IMS servers being monitored
Alert Manager	Alert Manager PAS	WLM Service Class SYSSTC
BMC AMI Ops Automation	BBI-SS PAS	The same WLM Service Class or a WLM Service Class with higher goals than any of the target subsystems or systems that the PAS manages If you use Total Object Manager (TOM), set the TOM WLM Service Class to SYSSTC. If the WLM Service Class assigned has a goal lower than the WLM Service Class assigned to the target subsystems or systems, loss of data or excessive storage usage could occur.
BMC AMI Ops Infrastructure	CAS	WLM Service Class SYSSTC
BMC AMI Ops Monitor for CICS	BBI-SS PAS	WLM Service Class with higher goals than the IBM CICS targets connected to the PAS This way, the PAS can process CMRDETL data that CICS creates in the common data space and manage the connections efficiently.
BMC AMI Ops Monitor for CMF	z/OS PAS	SYSSTC
BMC AMI Ops Monitor for Db2	BBI-SS PAS	WLM Service Class with higher goals than Db2 This setting is most important for the Db2 DBM1 and MSTR address spaces. It is not necessary for IRLM. If the BBI-SS PAS does not get enough resources to complete its work in a reasonable time period, U3912 or U3920 timeout abends can result. These abends are recoverable, but disruptive. This setting is recommended for most monitoring functions, but it is most important for detail traces. When a detail trace is requested by the user, BMC AMI OpsM for Db2 starts a Db2 trace by using the Instrumentation Facility Interface (IFI). Db2 GETMAINs a buffer in ECSA and uses this buffer to pass the detail data to BMC AMI OpsM for Db2 . If BMC AMI OpsM for Db2 processing cannot keep up with the Db2 activity (transferring the filled buffer), trace data is lost.
BMC AMI Ops Monitor for DBCTL	BBI-SS PAS	The same WLM Service Class or a WLM Service Class with higher goals than any of the target subsystems that the PAS manages If the WLM Service Class assigned has a goal lower than the WLM Service Class assigned to the target subsystems, loss of data or excessive storage usage could occur.
BMC AMI Ops Monitor for IMS Online	BBI-SS PAS	The same WLM Service Class or a WLM Service Class with higher goals than any of the target subsystems that the PAS manages If the WLM Service Class assigned has a goal lower than the WLM Service Class assigned to the target subsystems, loss of data or excessive storage usage could occur.
BMC AMI Ops Monitor for MQ	BBI-SS PAS	The same WLM Service Class or a WLM Service Class with higher goals than either the queue manager MSTR or the CHIN address space
BMC AMI Ops Monitor for Unix Systems Services	z/OS PAS	WLM Service Class SYSSTC
BMC AMI Ops Monitor for z/OS	z/OS PAS	WLM Service Class SYSSTC
BMC AMI Ops SYSPROG Services	z/OS PAS	WLM Service Class SYSSTC
BMC AMI Storage	BMC AMI Storage PAS	Use WLM Service Class SYSSTC Important BMC AMI Storage makes use of z/OS Enclave services, which allows you to use z/OS Workload Manager (WLM) to prioritize the work within the scope of the system. The address space must be given a high dispatching priority; however, you can assign lower priorities to much of the work within the address space by using WLM.
