Issue/Introduction

Trying to execute FLASH copies using Database Copier for IMS and getting error message
but no further messages from Snapshot Services are shown:


DBON30FE ERROR IN FLASH PREPARE

How to obtain additional messages from Snapshot to find out why this job step is failing.

Resolution

Message DBON30FE indicates a problem in Snapshot Services.

To produce additional diagnostic TGR prefixed messages, the following DD statements need to be added to the JCL:

 

 	//TGRMSGS DD SYSOUT=*
 	//TGRDTAIL DD DUMMY 	
 	//TGRDEBUG DD DUMMY

 

This specifies that snapshot general services or flash copy messages should be printed in DBOMSGS or SYSPRINT (without also issuing too much debugging details).
If the TGRMSGS DD is not allocated, these messages are not produced.

Review the TGR messages that are subsequently generated for information as to why the flash copy failed.
