Enabling open access to IMS data

To enable open access to IMS data, you need to set up IMS support for the IMS Universal drivers, configure the CSL Open Database Manager (ODBM), IMS Connect, and any required ODBM, IMS Connect, or Base Primitive Environment (BPE) user exits, and then start ODBM and IMS Connect.

The following high-level summary describes the steps for configuring IMS support for the IMS Universal drivers.

Procedure

  1. Configure SCI.
  2. Configure IMS to join the IMSplex that you configured in the previous step.
  3. Configure ODBM:
    1. Use the ODBM configuration member of the IMS PROCLIB data set (CSLDCxxx) to define the connections between ODBM and one or more datastores.
    2. Use the ODBM initialization member of the IMS PROCLIB data set (CSLDIxxx) to specify parameters that initialize the ODBM address space.
    3. Use the BPE configuration member of the IMS PROCLIB data set to define the BPE execution environment settings for ODBM.
  4. Optional: Write CSL ODBM user exit routines to customize and monitor the ODBM environment, and then define these user exit routines to BPE:
    1. Write CSL ODBM user exits to customize and monitor the ODBM environment.
    2. Specify the ODBM user exit routine in the BPE exit list member of the IMS PROCLIB data set.
    3. Specify the BPE exit list member in the BPE configuration parameter member of the IMS PROCLIB data set.
  5. Configure IMS Connect to communicate with ODBM.
    Use the ODACCESS statement of the IMS Connect configuration member of the IMS PROCLIB data set (HWSCFGxx) to define characteristics of the communication between ODBM and IMS Connect.
  6. Use the BPE configuration member of the IMS PROCLIB data set to define the BPE execution environment settings for IMS Connect.
  7. Optional: Write IMS Connect user exit routines to configure the connection to ODBM, and then define these user exit routines to BPE:
    1. Use the routing exit HWSROUT0 to override the IMS alias or select an ODBM.
    2. Use the IMS Connect DB security user exit routine, HWSAUTH0, to authenticate the input user ID and password specified by IMS Connect clients.
    3. Specify the IMS Connect user exit routines in the BPE exit list member of the IMS PROCLIB data set.
    4. Specify the BPE exit list member in the BPE configuration parameter member of the IMS PROCLIB data set.
  8. Optional: Set up tracing for the BPE-managed ODBM address space.
  9. Set up security for ODBM.
  10. Set up security for IMS Connect.
  11. Develop and deploy applications by using the IMS Universal drivers.
    You can also set up and deploy from external environments.
  12. Start the following components:
    1. Start the Structured Call Interface (SCI).
    2. Start the Operations Manager (OM).
    3. If SCI is newly enabled for IMS, restart IMS.
    4. Start the IMS control region.
    5. Start ODBM.
    6. Start IMS Connect.
