How do I display non-managed, SCOPE=SYSTEMS resources using CA MIM?
The MIM DISPLAY COUNTS can display both managed and non-managed ENQ/RESERVE activity. At prior releases of CA MIM, this display showed reserve requests only by default. This resulted in many customers not being made aware of enqueue resources not being converted by MIM, thereby creating data integrity exposures. At release '11.8', a CA MIM Best Practice was added to ensure customer's set the parameter value from "RESERVES" to "SYSTEMS" to ensure statistics were accumulated on RESERVES and SCOPE=SYSTEMS ENQs.
If a parameter change is required, one can be achieved via this MIM command:
F MIM,SETOPT GDIF COUNT=SYSTEMS
If a parameter change was required, wait a couple of days for enqueue activity to gather before issuing the MIM DISPLAY COUNTS command on all systems. This is to allow time for the statistics to gather, making your findings more accurate.
Below is the interpretation of the DISPLAY COUNTS command output. For the nature of this topic, we'll only be focused on the RESOURCE and TYPE fields:

RESOURCE TYPE ------ ENQS ------ ----- RESERVES ----- GLOBAL
(QNAME) ISSUED PROCESSED ISSUED PROCESSED CONFLICTS
SYSIGGV2 S 0 0 8920079 8920079 12820
SYSDSN M 1607199 1601727 0 0 2292
SYSVSAM S 875886 573954 0 0 15483
*SYSZVVDS 926 0 10342981 0 0
*SYSVTOC 613694 0 1963195 0 0
*SYSZJES2 0 0 56652 0 0
In this example, SYSIGGV2, SYSDSN, and SYSVSAM resources are being managed by CA MIM, while SYSZVVDS, SYSVTOC, and SYSZJES2 are not being managed. Note that the GDIINIT NMCOUNT=x and SETOPTION GDIF COUNT=y parameters control the volume and type of non-managed ENQ/RESERVE data presented by the DISPLAY COUNTS command.
Resources that are not managed via MIM have an asterisk (*) to the left of the resource field. In this example, SYSZVVDS, SYSVTOC, and SYSZJES2 are not being managed, while SYSIGGV2, SYSDSN, and SYSVSAM resources are being managed by CA MIM.
This field indicates the SCOPE value on the qname statement, of which there are four possibilities:
