Error description
You use the CPSM WUI to look at active tasks in a CICS region. This view allows you to purge running tasks. This includes tasks that are running as part of the CPSM MAS agent code. These tasks should not be purged. They should be considered system tasks. In order to prevent accidental purging of these tasks through the WUI, CICS Explorer, or CPSM API program, this APAR is being opened to protect them. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V5R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: You use the CPSM WUI to display all * * active tasks in a CICS region. During * * an emergency, you select all tasks and * * click Purge to FORCEPURGE all active * * user tasks. This also purges tasks * * that are running as part of the CPSM * * MAS agent code. The MAS agent must be * * restarted by entering the COLM trans- * * action, or by recycling the region. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes and MASes must be recycled * * to pick up the new code. Note that regions * * do not need to be brought down and restarted * * at the same time. However, in order that * * MAS agent tasks be protected in a MAS, the * * CMAS to which the MAS connects must be re- * * started with MASTASKPROT(YES) added to the * * CMAS EYUPARMs. After the CMAS is restarted * * protection can be enabled in each MAS by * * bringing down and restarting the CICS region * * or by stopping the MAS agent using the COSH * * transaction, and restarting it using the * * COLM transaction. * * If CICS Explorer or another client that * * uses the CICS Management Client Interface * * (CMCI) is used to manage a CICSplex, or a * * user program uses the CPSM API to manage * * TASK resources, the CMAS to which the server * * or API program connects must be restarted * * to enable support for MAS task protection. * **************************************************************** The CPSM MAS agent tasks run as user tasks and can be modi- fied or purged through the CPSM API, Web User Interface (WUI), or CMCI clients like CICS Explorer. CICS does not support protecting running tasks through an external security manager.
Problem conclusion
A new CMAS EYUPARM, MASTASKPROT, makes it possible to prevent modification or purging of CPSM MAS agent tasks through the CPSM API, WUI, or CMCI. It does not prevent individual CPSM tasks from being purged using the CEMT transaction or by a program executing CICS SPI commands.
