HISTORY-STATS-TIME SYSPARMS default value within Sysview for Db2 affecting interval value

Products

• SYSVIEW Performance Management Option for DB2 for z/OS

Issue/Introduction

After upgrading to Sysview Performance Management Option for Db2 for z/OS (IDB2) r20 the online
System History List (#2 option on main panel) is now displaying 15 minute intervals instead of 30 minute.

Resolution

The Sysview Performance Monitor for Db2 for z/OS Guide is not complete in describing this value. 

The guide should differentiate between the Default in the Sysparms file, and the Default if not coded (if they are different).
In this case the guide neglected to mention them both. The default in the Sysparms is 30 minutes.
The default, if not coded, is 15 minutes. The documentation will be updated to reflect that.
