What to do when data files fill up

If data store VSAM files that you have defined are too small or there are not enough of them to store all job logs you need to be online, you might encounter the files fill-up condition that hangs all data store activities. If this happens, there are two things you can do:

• Enlarge primary index, secondary index and data files sizes.
• Define some new data files; to do this you need to define one or more VSAM Data Files and to add them to data store startup procedure, using correct DDNAMEs (refer to IBM Tivoli Workload Scheduler for z/OS Planning and Installation Guide); the files are automatically initialized at the first data store startup.
  Note:

  The primary index is always reconstructed during IMPORT phase. It is also possible to combine the two strategies.
