Does CA ROSCOE use JES2 macros $CKW $XREQ HASPCKDS HASPCKPT HASPXCF $CKPWORK HASMPCE1? Are the CA Roscoe JES2 interfaces affected by these updates?
You can check the output from ROSGBL and ROJES2XT assemblies to check on the JES2 Macros. These are the only places where JES2 Macros are used in Roscoe.
The JES2 macros $CKW $XREQ HASPCKDS HASPCKPT HASPXCF $CKPWORK HASMPCE1 for allowing automatic JES2 checkpoint tuning do not affect CA Roscoe at all.
