Issue/Introduction

After upgrading from Gen 8.5 to Gen 8.6, and attempting to build remote file(s) (.RMTs) within the Gen z/OS Implementation Toolset, get the following error during the COMPOSE step of the build process: 

'           '  is invalid transaction code   (load module   ' 

 

 

Environment

Release : 8.6

Component : Gen MVS Implementation Tool

Resolution

The error message received is masking the actual problem after upgrading from Gen 8.5 to 8.6 on the z/OS IT. 

This is a size/memory issue with the PARMLIB configuration settings for Gen 8.6.  Compare the member PARMLIB(TIUIT) in Gen 8.5 versus the Gen 8.6 install for this same member.  

First place to look is the settings:
"TIUDASD=SYSDA  
TIUTBLK=27920  
TIUDASZ=750,375"

These are defaults, customers may need to increase the TIUIDASZ (ex. 1500, 1000) for the same blocks we show here.   Best to compare the PARMLIB(TIUIT) members entire settings from Gen 8.5 to 8.6 and update the Gen 8.6 member to match a working Gen 8.5 of the same member.  Then attempt to build the remote file(s) within the Gen 8.6 z/OS Implementation Toolset.
