Static PSBs

Static PSBs are existing PSBs generated by the database administrator.

Advantages of using a static PSB

  • It is easier to exclude segments from processing.
  • Processing options (PROCOPTs) can be used to limit the update capability of the user.
  • They are easily secured.
  • The PSB is available for use if Batch Backout is required.

Disadvantages of using a static PSB

  • A database administrator must generate the PSB.

IMS system considerations for BMP support

If you plan to use a static PSB to access databases in BMP mode, do the following steps:

  • Use the APPLCTN macro or the CREATE PGM command to declare the PSB.
  • Use the ACB Maintenance utility or the ACB Generation and Catalog Populate utility (DFS3UACB) to generate an ACB for the PSB.
