Appendix K. Multiple environment considerations

A CICS region can contain multiple production environments. If you want CEDS to work with all of these environments, you should set up a load edit environment for each of them. This forms a pair of environments for each of the production environments in the region.

When you want to process data for a particular production environment, either sign on to that environment or to the load edit environment that you set up. Run the DSLD transaction to process data from the interface file set up for this pair of environments. When CEDS has processed all of the data for these environments, run the DSTP transaction. This stops the processing for this pair of environments. You can then repeat the process for each pair of environments that you have.

When you set up multiple environments, make sure that you meet the following requirements:

• There is only one BOMWORK (EMTDB0E EMTDBIE) database per CICS region.

• There is only one PSB (EMTPLDE) for the program that starts the load process (EMTODSLD).

• There is only one PSB (EMTPTPE) for the program that stops the load process (EMTODSTP).

• There is an 'E' suffix PSB (EMTPCTE) for the control program (EMTODSCT) and one PBS (EMTPCTx), where x is the environment code, for each environment in the CICS region.

• The is one PSB for each environment in the CICS region for PSBs that have names starting with "EMTP".

• There is one PSB for each load edit environment in the CICS region for PSBs that have names that do not start with "EMTP".

• There is a DBD for each load edit environment in the CICS region, for the following DBDs:

  ACHIXDx

  ACHNDx

  BOMEXPx

  BOMIMPx

  DCND1Px

  DCND2Px

  ENZDPMx

  LLCCXxI

  LLCCXxT

  PRDEFDx

  PRIDXDx

  WORKSxM

  WSIDXDx

  Note: x = the environment code.

• There are CICS table entries for each DBD and PSB.

• You have created FCT CICS table entries for each environment in the CICS region for the following:

  EMTVMKx

  EMI interface file

  EMTVEKx

  PES interface file

  EMTVDKx

  PDI interface file

  EMTVIKx

  Interlock file

  Note: x = the environment code.

• You have created one FCT CICS table entry for each of the following:

  EMTV1KE

  PES feedback file

  EMTV1EE

  PDI feedback file

• There is one VSAM file in each CICS region for each of the following:

  EMTV1KE

  PES feedback file

  EMTV1EE

  PDI feedback file

  EMTVIKE

  Interlock file

• There is one VSAM file for each load edit environment for each of the following:

  EMTVMKx

  PES feedback file

  EMTVEKx

  PDI feedback file

  EMTVDKx

  Interlock file

  Note: x = the environment code.

• The interlock file has one DD / DLBL statement for each environment in the CICS region. These statements should reference the one VSAM file for this region. For example:

    //EMTVIKE  DSN=COPDB.EMTVIKE........
    //EMTVIKX  DSN=COPDB.EMTVIKE........
    //EMTVIKU  DSN=COPDB.EMTVIKE........
    //EMTVIKI  DSN=COPDB.EMTVIKE........
  

• The interface files have one DD / DLBL statement for each environment in the CICS region. These statements should pair a load edit with a production environment. For example:

    //EMTVEKE  DSN=COPDB.EMTVEKE........
    //EMTVEKX  DSN=COPDB.EMTVEKE........
    //EMTVEKU  DSN=COPDB.EMTVEKN........
    //EMTVEKI  DSN=COPDB.EMTVEKN........
  

• There should be an environment table for each environment in the CICS region.
