Issue/Introduction

For one CSI(DB2 Tools) user getting error 500 on z/OSMF Software Toolkit interface(PTF Summary). Also this issue appears only if more than 4 FMIDs selected in 'SWI/CSI Selection' settings. 

Below screenshot shows the actual reason for error 500 in browser dev tools. 

NOTE: On SYSVIEW panels(CSIQUERY) issue not appears. 

Cause

SYSVIEW REST API which is serve communication between SYSVIEW and z/OSMF Software Toolkit has timeout for each request, and by default it's 30 seconds the max value is 60. 

Resolution

The reason that user getting error 500 is the fact that CSI has a lot of FMIDs and more that 7000 PTFs, combination of those factors cause timeout issue that will be throwing 500 error. Advised to try increase timeout value in SYSVAPPS application.yml to 60 seconds and that worked.

NOTE: Alternatively, when max timeout still not enough, users could consider making fewer entries for same CSI on z/OSMF Software Toolkit SWI/CSI settings such that each entry will select different FMIDs.
