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.
