Painful DB2 for z/OS Batch Performance Problems

Can’t quickly find which bad DB2 for z/OS SQL statements to tune

1)

Batch Jobs fight for DB2 resources – too many deadlocks and time outs occurring

2)

Painfully long DB2 program ROLLBACKS are occurring or catastrophically long ROLLBACKS could occur…

3)

Problem#1: Can’t Find Costly SQL Statements to Tune

DBAs and Application Developers don’t know what to tune – SQL is hidden within thousands of DB2 batch Jobs and programs

1)

DBAs and Developers can identify long running batch Jobs but have no idea whether DB2 SQL access is the cause

2)

No one really knows whether SQL continues to perform well after it has been placed into production

3)

No one wants to use their DB2 for z/OS performance monitor at 2:00 am!!!

4)

Batch Analyzer


Batch programs fight for DB2 resources in the middle of the night and the whole batch window is slowed down

1)

Programs with poor COMMIT frequency use excessive DB2 resources

2)

24 X 7 shops experience batch Jobs timing out during the day – online and batch performance is impacted

3)

Problem#2: Can’t Prevent DB2 Deadlocks and Timeouts

-5-

Batch Analyzer


Problem#3: Fear of (or) Experiencing Long DB2 ROLLBACKS

Most DB2 batch programs in production do not have proper DB2 COMMIT logic

1)

DB2 for z/OS programs that fail take twice as long (or more) to ROLLBACK

2)

DB2 ROLLBACKs keep everyone from getting their DB2 work done

3)

DBAs are not certain whether horrible DB2 ROLLBACK disasters are waiting to happen…

1)

Locate all DB2 programs experiencing Deadlocks or Timeouts, or that need COMMIT tuning

2)

PROOF OF CONCEPT OVERVIEW

Some Very Important Batch Analyzer Facts!

Performance data can be collected for all DB2 batch jobs or can be filtered using standard DB2 masking

�

No JCL changes or program changes are required�

Collection overhead is incurred only when DB2 batch Jobs are executed – total system impact is far less than Detector, Apptune, or traditional DB2 monitors

�

-8-

Batch Analyzer


More Very Important Batch Analyzer Facts!

Batch Analyzer overhead typically runs 1% - 5% overhead for each batch Job

�

-9-

Only summary performance data is collected –DASD consumed even over long lengths of time is minimal

�

The Batch Analyzer Touch Free Collector can be started and stopped instantly with a single command
