Nov 13, 2013 Important info on APAR PM80542/UK91650
With APAR PM80542/UK91650, which was included in z/VSE 5.1.2 Upgrade, the transaction security phase DTSECTXN was delivered by error. This phase will get active in the system replacing transaction security settings for IBM provided transactions in case the new security concept based on BSTCNTL definition is used. If not yet migrated to the new concept it will even replace all customer defined transaction security settings.

In case the new concept is used (you can find out using IUI dialog 285, you will not get migration offered) delete DTSECTXN.PHASE from IJSYSRS.SYSLIB.

If the old concept is used, there should be the original phase stored in PRD2.SAVE, the new (IBM transactions only) phase in IJSYSRS.SYSLIB. It is recommended to merge the new IBM definition into existing setup as follows:

Jul 26, 2012 PM67737: Customers who have developed, maintained or rebuilt COBOL/VSE applications on z/VSE 5.1 prior to installing UK80309 should apply this APARs PTF and then re-link all z/VSE 5.1 updated COBOL/VSE applications. COBOL/VSE applications that have not been linkedited on z/VSE 5.1 are not affected and do not require any action. APAR PM69182 is available for z/VSE 4.3 COBOL/VSE users as a preventative solution.
