Working with the RACF database

z/OS Security Server RACF Diagnosis Guide
GA32-0886-00

To update or examine a data set in the RACF® database, perform the following steps:
  1. Decide which data set in the RACF database you want to work with, and enter BLKUPD.
    Note: After entering the BLKUPD command, you can use the following subcommands: LOCATE, READ, or END.
  2. Decide which block on the database you want to work with. If needed, use the LOCATE subcommand to assist you in finding the specific block.
  3. Enter the READ subcommand, specifying either UPDATE or NOUPDATE.
  4. Enter the subcommands of READ necessary to accomplish your task.
  5. Issue the END command to end the utility.

Note that ALIAS index blocks are not supported by this utility. It is possible to use the LIST and the REP subcommands with ALIAS index blocks but great care should be taken since there is no format checking.

For more information about the alias indexes, see Alias index blocks.
