Starting the CSL ODBM

You can start ODBM either before or after starting IMS, IMS Connect, or z/OS® Resource Recovery Services (RRS).

If ODBM and an IMS system are not members of the same IMSplex, ODBM automatically connects to the IMS system only if the IMS system is started before ODBM.

To enable ODBM to connect to the IMS system automatically regardless of the order in which ODBM and IMS are started, use either the DFSCGxxx member of the IMS.PROCLIB data set or the Common Service Layer section of the DFSDFxxx PROCLIB member to define the IMS system as a member of the same IMSplex as ODBM.

The options for starting ODBM include:

The system operator can use a z/OS started procedure. For example, CSLODBM, a sample started procedure that is shipped with IMS, can be modified for your installation, or you can identify your own started procedure. To start an ODBM address space with a started procedure, issue the z/OS START command as follows:
```
S odbmjobname
```
odbmjobname is the job name of the ODBM address space to be started.
The system operator can submit JCL that starts the started procedure.
