Issue/Introduction
Description:
This Knowledge Document shows one possibility how to use the "dynamic PSB feature" of the CA MAX IMS Software to browse an IMS data base.
Solution:
Important note: There is another Knowledge Document, called "How to prepare using the CA MAX IMS dynamic PSB feature?" what shows which steps need to be done in order to use the feature as shown below.
- After invoking MAX IMS, enter "0" in the input field next to "0. Profile parameters" on the MAX IMS/UTIL main panel.
- Complete the following, at least the bold, fields:
MAX ---------------------- IMS/UTIL PROFILE OPTIONS ---------------------- MAX

For DBDLIB and PSBLIB enter the names of up to two partitioned data sets containing standard DBD/PSB load modules defined for each IMS database to be accessed. These load modules are produced from the standard output of the IMS DBDGEN/PSBGEN process.
- After leaving the PROFILE panel, enter 1 for "Browse database" and your IMS system ID, as well as the PCB name of your IMS database.
In the PSB name field enter "DYNAM" as follows:MAX IMS/UTIL -------------- SPECIFY A DATABASE NAME ------------- MAX IMS/UTIL
COMMAND ===>
Select one of the following. Then press Enter.

DYNAM can only be used, if using the dynamic PSB feature was prepared as explained e.g. in the Knowledge Document called "How to prepare using the CA MAX IMS dynamic PSB feature?". - On the next screen enter the DD names and the physical data set names of your IMS data base:
