EQQN043E ERROR ON LOGICAL FILE JS RC08 RSN0028 after moving to TWSz 8.6

Flash (Alert)


Abstract

VSAM I/O ERROR on EQQJS1DS or EQQJS2DS. Requested function is ISRT from EQQJHPUT. VSAM RETURN CODE IS 8, REASON CODE IS 0028. Error occurs after migrating to TWSz V8R6 from any prior release.

Content

MESSAGE EQQN043E RC08 RSN0028 means the specified VSAM FILE is full, and "Data set cannot be extended because VSAM cannot allocate additional direct access storage space. Most probably there is not enough space left to make the secondary allocation."

Tivoli Workload Scheduler for z/OS is updated in Version 8, Release 6 to accept EXTENDED FORMAT VSAM files as EQQJS1DS and EQQJS2DS. As part of that enhancement, the meaning of the value specified in the JTOPTS MAXJSFILE keyword is changed from KILOBYTES (1024) to MEGABYTES (1024KB). So when migrating to 8.6 from any prior release, if the MAXJSFILE parameter is not updated, the specified maximum allowable size of the JSFILE is "magically" multiplied by 1024.

If this problem occurs, the first thing to do is to force an immediate swap of the JSFiles (along with recovery of space currently occupied by deleted records) by running a job like this:

****************************** Top of Data *******************
//BACKUPJS JOB (),'OPCTEST',CLASS=A,MSGCLASS=X,
// MSGLEVEL=(1,1),NOTIFY=twsuser
//*
//* THIS JOB WILL CREATE AN EXS EVENT RECORD TO CHANGE THE STATUS
//* THE SPECIFIED SPECIAL RESOURCE AS INDICATED.
//*
//UPDTSR EXEC PGM=EQQEVPGM
//STEPLIB DD DSN=TWSZ.V8R3M0.SEQQLMD0,DISP=SHR
//EQQMLIB DD DSN=TWSZ.V8R3M0.SEQQMSG0,DISP=SHR
//EQQMLOG DD SYSOUT=*
//SYSIN DD *
BACKUP RESDS(JS) SUBSYS(O86T)
//*
//* The SUBSYS keyword must name the TRACKER on the system where
//* this job will run
/*EOF
***************************** Bottom of Data *****************

Then, if the JTOPTS MAXJSFILE() parameter contains a numeric value, divide that value by 1024 and update the parameter with the result. This change will take effect the next time the CONTROLLER is restarted, and will prevent future occurrences of the problem.

Also, the following documents contain a great deal of useful information regarding the care and feeding of the JSFiles:
