Detail line descriptions

Each line reports values under the following headings.
  • TCB Name
  • Address
  • Samples
  • CPU Active
  • CPU WAIT
  • Queued
TCB Name
This is the name of the program associated with the task; the one specified to the ATTACH function. An index value is also appended to the name. This is a sequence number that Application Performance Analyzer assigned to each unique TCB that it observed. The value is useful for distinguishing between more than one TCB with the same name (same program ATTACHed).

For CICS® measurements that have the CICS data extractor selected, the TCB mode will be displayed for CICS TCBs. This will immediately follow the TCB name.

Address
This is the address of the TCB. Only 6 hexadecimal digits are shown as TCBs always reside below the 16MB line.
Samples
This is the number of samples in which the TCB was observed.
CPU Active
This is the number of samples in which the CPU was active (instruction execution was in progress) in this TCB.
CPU WAIT
This is the number of samples in which the Task was waiting.
Queued
This is the number of samples in which the TCB was observed in Queued status; it was ready to execute but no CPU was available.
