Issue/Introduction

Description:

We have encountered two abends today, following the upgrade from TPX 5.0 to TPX V5.2 SP00 overnight. TPX has recovered, without any intervention.

Here is an extract from the TPX task log:

Solution:

Exit TPXUCMND SAMPLIB changed at some point since TPX 5.0 to include a buffer size calculation so that this type of error can be avoided.

In the above instance, the customer had an older version of the exit that they had previously customized. For the upgrade, they simply reassembled their old exit with the new release libraries. This did not include the new buffer calculation code.

When upgrading to a new release, you need to compare these libraries:

• original vendor source
  
  
• new vendor source
  
  
• your custom code, such as exits

For example, with SAMPLIB, compare original vendor SAMPLIB to new vendor SAMPLIB.

• If they are identical, then reassemble your custom version with new release libraries. No custom source changes should be necessary.
  
  
• If there are differences, then you need to merge the vendor source changes and your custom version to obtain the new custom version. Then reassemble the new custom version with the new release libraries.

You need to do this for all custom code that you have including JCL and PROCs.
