Issue/Introduction

How can the URI REUSE feature be enabled in release 15.0/15.1?

Is it via a MUF startup parameter?

 

 

Environment

Release : 15.1

Component : CA Datacom/DB

Resolution

There is no MUF startup parameter required to use the URI Reuse feature.

This feature was introduced in 15.0 and is activated automatically when the URI count for an area reaches 3G and the URI-REUSE Datadictionary attribute for the AREA is set to Y (Yes). This can be set online or using batch transaction 3002.

When the URI count reaches 3G (3,221,225,472), an asynchronous scan of the data area is scheduled in the MUF. This URI scan uses a new system task with a jobname of ***DBURI.

With 15.1, this process was enhanced with PTF SO10439, now the MUF automatically forces the CXX URI REUSE setting to YES when the high URI value reaches 3G.

When the URI scan starts the following message will be issued:

DB02812I URI REUSE SCAN AND INDEX BUILD started/ended FOR BASE nnnnn AREA aaa

If the MUF is unable to schedule a URI scan, the following message is issued:

DB02801W BASE nnnnn AREA aaa URI OVER 3G
