Registering Fast Path databases in DBRC

Although Fast Path databases are not required to be registered in DBRC in order for the error handling to work, registration is highly recommended. In some situations, registration is required.

If an error occurs on a database that is not registered and the system stops, the database could be damaged if the system is restarted and a /DBR command is not issued before accessing the database. The restart causes the error buffers to be restored as they were when the system stopped.

In the following situations, Fast Path databases must be registered to DBRC:
  • Virtual Storage Option (VSO)
  • Preopening DEDB areas
  • Preloading a VSO DEDB area control interval (CI)
  • High speed sequential processing (HSSP) image copy (IC)
  • Multiple area data set (MADS)
  • Full segment logging
  • Database quiesce
  • Data sharing
  • Shared Virtual Storage Option (SVSO) areas that reside on a z/OS® coupling facility structure
