DFHMCT TYPE=EMP entries for DBCTL
The following MCT entries make use of the two event-monitoring points in the
performance class used by the CICS-DBCTL interface modules:
These MCT entries are coded in the sample copy book DFH$MCTD.
The DBCTL data recorded by these event monitoring points can be mapped using
the IMS macro DFSDSTA DSECT=YES, which is available in the IMS genlibs.
For more information about monitoring in DBCTL, refer to the

v Wait for storage in the UDSA
v Wait for storage in the SDSA
v Wait for storage in the RDSA
v Wait for storage in the ECDSA

v Wait for storage in the ESDSA
v Wait for storage in the ERDSA
v Wait for auxiliary temporary storage
v Wait for auxiliary temporary storage string
v Wait for auxiliary temporary storage buffer
