I'm very new to IDMS and I'm trying to find out where the database connections can be specified for COBOL programs accessing the database.
From what I can work out from the documentation the possibilities are:
- SYSIDMS and SYSCTL statements in the JCL that runs the program
- A SYSIDMS load module
- An IDMSOPTI load module
- A BIND RUN-UNIT statement within the COBOL program
- Session defaults?
Is this correct/all possibilities?
What is the precedence, I.e. if I specify it in a BIND RUN-UNIT and in the JCL which one will be used?
What other things are necessary for a program to make a connection to an IDMS database?
If anyone has more information on these things it would be greatly appreciated.
