Monitoring DB2

Accounting and monitoring in a CICS® DB2® environment.

CICS-supplied accounting and monitoring information
CICS includes several facilities that provide accounting and monitoring. You can use these facilities to measure the use of different resources in a CICS system.
DB2-supplied accounting and monitoring information
The instrumentation facility component of DB2 enables you to use six types of traces: statistics, accounting, audit, performance, monitor, and global. For each trace type, you can activate a number of trace classes.
Monitoring a CICS DB2 environment: Overview
The objective of monitoring the CICS DB2 attachment facility is to provide a basis for accounting and tuning.
Monitoring the CICS DB2 attachment facility
Monitor the CICS DB2 attachment facility by using commands addressed to both DB2 and the CICS DB2 attachment facility itself.
Monitoring CICS transactions that access DB2 resources
CICS provides accounting and monitoring facilities for the resources required by CICS transactions in the CICS address space.
Monitoring DB2 when used with CICS
Use the SMF or GTF records produced by DB2 to monitor DB2 usage with CICS .
Monitoring the CICS system in a CICS DB2 environment
You can monitor the activity of the CICS DB2 TCBs using the CICS dispatcher statistics.
Accounting in a CICS DB2 environment: Overview
Accounting in a CICS DB2 environment can be used to analyze the transactions being executed in the system, and to charge back the total amount of resources consumed for a given set of transactions to a well-defined set of users. The user can be a real user, groups of users, transactions, or any other expression for the unit to which the resources must be appointed.
Accounting information provided by the DB2 accounting facility
The DB2 accounting facility provides detailed statistics on the use of DB2 resources by CICS transactions. You can use DB2 accounting records as the basis for the accounting and tuning of DB2 resources used by CICS transactions.
Relating DB2 accounting records to CICS performance class records
To see a complete picture of the usage of resources by each CICS transaction in both the CICS and DB2 address spaces, you must match up the data in the DB2 accounting records with the data in the CICS performance class records.
Accounting for processor usage in a CICS DB2 environment
Information about processor time consumption is provided in the DB2 accounting and statistics trace records. You can use these records to calculate the total processor time used in CICS and DB2.
