MERGE abend U1547 after Disk maintenance upgrade
The abend U1547 after a CA Disk maintenance upgrade is caused by a mismatch between the PARMEDIT member in the CCUWPARM and the load library CCUWLOAD. A PTF has introduced a new Sysparm or changed an existing Sysparm in CCUWPARM member PARMEDIT, but the new member is not taken over together with the new CCUWLOAD.
Take over the new delivered PARMEDIT member into your active CCUWPARM.
