Issue/Introduction

The IXX area for CA Scheduler may become full; this outlines the options for how that can be handled.

Environment

Release: 11.0
Component: SCHDMS

Resolution

CA Scheduler may issue CACM335E when a the index area is approaching being full:

CACM335E CA-DATACOM AREA IXX IS 89% FULL

When a site receives an error CACM335E for the IXX area, there are a few options to consider or explore:

• Normally the database index and data areas are defined with dynamic extend turned on. If the file becomes 100% full in the current extents, Datacom will dynamically allocate a new file extent (up to the operating system limit). To confirm that dynamic extend is turned on for the database, please run a DBUTLTY job as follows and review the output:
  

  //CXXREPT  EXEC PGM=DBUTLTY
  //STEPLIB  DD DISP=SHR,DSN=DCOMAD.CUSLIB    Use the same STEPLIB as the MUF
  //         DD DISP=SHR,DSN=DCOMAD.CAAXLOAD  
  //CXX      DD DISP=SHR,DSN=DCOMAD.CXX       And the same CXX dataset (not needed for Version 15.0 or higher)
  //SYSPRINT DD SYSOUT=*
  //SNAPER   DD SYSOUT=*
  //SYSUDUMP DD SYSOUT=*
  //SYSIN    DD * 
  COMM    DBID=430,OPTION=STATS
  REPORT  DBID=430,AREA=CXX,TYPE=A
  REPORT  DBID=430,AREA=CXX
  /*

  Look for "DYNAMIC EXTEND - YES"  and DYN.EXT.TRACKS in the report for the IXX area to confirm that dynamic extend is active with non zero value. If the DYN.EXT.TRACKS value is zero, the secondary allocation from the cataloged file will be used.

         DYNAMIC EXTEND -    YES
         DYN.EXT.TRACKS -     300

         Check ISPF 3.2 to see how many extents the data set currently is using.

• For the IXX area you can get some reduction in space by running a DEFRAG.
  
  See the Scheduler SAMPJCL member DBDEFRAG for JCL which will do this.
  
  
• The operating system will allocate up to 16 extents before you have to allocate a larger file and backup and load the database.
  
  See the Scheduler SAMPJCL member DBRESIZE to increase the IXX and/or any of the data areas.
