Correlating by CICS BTS process ID (root activity ID)
The CICSĀ® Business Transaction Services (BTS) process ID (owner: DFHCBTS, field ID: 202), also known as the root activity ID, can be used to correlate the performance class records for the transactions that CICS runs that form part of the same process ID.
Note: Not all transactions that use CICS Business
Transaction Services have a process ID assigned at transaction attach.
However, the CICS PA BTS
report includes all the performance class records for transactions
that have used any CICS BTS
services regardless of whether they have been assigned a process ID
at transaction attach. In this case, whether the performance class
records form part of the same process ID is determined by comparing
the transaction sequence number field (owner: DFHTASK, field ID: 031).
For detailed information on the monitoring data provided for the CICS Business Transaction Services (BTS) support, see the section on the DFHCBTS group of data fields in the CICS Performance Guide.
