HTH, -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Wendell Lovewell Sent: Friday, January 19, 2024 3:33 PM To: [email protected] Subject: How can I keep JES2 from being SYSPLEXed? [CAUTION: This Email is from outside the Organization. Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] I have two systems that I want to share dasd and allow for VSAM RLS between the systems, but I don’t want to SYSPLEX JES2. I have MASDEF SHARED=NOCHECK. What else can I do to un-sysplex JES? Is it safe to delete the JES2 and/or SYSJES group definitions from XCF? I don't have a JES_CKPT_1 structure defined at all. Background: I’m trying to add a z/OS 3.1 (&SYSNAME S0W1) to a sysplex where z/OS 2.5 (Z3-&SYSNAME S0W3) is running, but ONLY for VSAM RLS. I don’t want to “plex” anything more than is needed for VSAM/RLS—not JES, not SYSLOG, not VTAM, not SMF or anything else. The systems are running fine stand-alone (each with their own set of disks, including the volume with the CDS), but when I try to use the same CDS disk between the systems, the first system comes up fine, but JES2 on the system brought up last complains that it cannot find the checkpoint datasets of the OTHER system: Z4 : H *$HASP284 JES2 INITIALIZATION CHECKPOINT DIALOG STARTED Z4 : H *$HASP277 JES2 CAN NOT FIND OR USE THE CHECKPOINT DATA SET(S) Z4 : H THAT WERE IN USE WHEN THE MAS WAS LAST ACTIVE BECAUSE VOLUME Z4 : H FOR CKPT1 NOT MOUNTED Z4 : H * Z4 : H CURRENT CHECKPOINT VALUES: Z4 : H CKPT1=(DSNAME=SYS1.HASPCKPT,VOLSER=B5SYS1,INUSE=YES), Z4 : H CKPT2=(DSNAME=SYS1.HASPCKP2,VOLSER=B5CFG1,INUSE=YES) Z4 : H * Z4 : H VALID RESPONSES ARE: Z4 : H CKPT1=... - UPDATE CURRENT CHECKPOINT SPECIFICATION WITH Z4 : H CKPT2=... THE VALUES USED WHEN JES2 MAS WAS LAST ACTIVE Z4 : H 'RECONFIG' - THE CHECKPOINT DATA SET(S) THAT WERE IN USE Z4 : H WHEN JES2 WAS LAST ACTIVE ARE NO LONGER Z4 : H AVAILABLE (ALL-MEMBER WARM START ONLY) Z4 : H 'CONT' - ATTEMPT INITIALIZATION WITH THE VALUES LISTED Z4 : H 'TERM' - TERMINATE JES2 INITIALIZATION ON THIS MEMBER Z4 : H *04 $HASP272 ENTER RESPONSE (ISSUE D R,MSG=$HASP277 FOR RELATED MSG) "Z4" is the z/OS 3.1 system. The “B5SYS1” and “B5CFG1” volumes belong to the z/OS 2.5 system. If I bring up z/OS 3.1 with z/OS 2.5 down and then try to bring up z/OS 2.5, the same message is displayed except it identifies the volumes belonging to the other system. I can RECONFIG with the correct CKPT volumes, but it always ends with: Z4 : $HASP478 INITIAL CHECKPOINT READ IS FROM CKPT1 Z4 : (SYS1.HASPCKPT ON A3SYS1) Z4 : LAST WRITTEN THURSDAY, 18 JAN 2024 AT 21:57:08 (GMT) Z4 : $HASP792 JES2 HAS JOINED XCF GROUP JES2 THAT INCLUDES ACTIVE MEMBERS Z4 : THAT ARE NOT PART OF THIS MAS Z4 : MEMBER=JES2$S0W3,REASON=DIFFERENT COLD START TIME Z4 : $HASP428 CORRECT THE ABOVE PROBLEMS AND RESTART JES2 Z4 : IXZ0002I CONNECTION TO JESXCF COMPONENT DISABLED, Z4 : GROUP JES2 MEMBER JES2$S0W1 Z4 : $HASP9085 JES2 MONITOR ADDRESS SPACE STOPPED FOR JES2 Z4 : $HASP085 JES2 TERMINATION COMPLETE Like I said, I don't want a MAS at all--each JES2 should be separate.
