• RC/Query for DB2 for z/OS

Issue/Introduction

When using RC/Query for Db2 for z/OS (RCQ) doing the DDL command on an object receives the following message:
RQ078E - Command requested is not valid for selected object

Resolution

Check the hlq.CDBAPARM for an ENABLExx member.  If this member contains RCQ_OFS(NO) remove it. 
Object Framework Services (OFS) is a services layer that is used to perform Db2 system catalog access and generate DDL.  If this 
is set to NO then an older code path is being used which will not produce correct results.  With the parameter removed OFS will be used to 
generate DDL.
