Each user of the Datacom Data Adapter needs access to a number of libraries. Three of these libraries were created during FOCUS installation. You must create one additional library as part of the data adapter installation. |
In this section: |
A stored FOCUS procedure is called a FOCEXEC. A FOCEXEC is stored as a member of a partitioned data set (PDS) allocated to ddname FOCEXEC in the JCL or CLIST used to run FOCUS. The FOCEXEC PDS was created when FOCUS was installed.
The FOCUS description of a Datacom data source is called a Master File. It is stored as a member of a PDS that is allocated to ddname MASTER in the JCL or CLIST used to run FOCUS. The MASTER PDS was created when FOCUS was installed.
Each Master File must have an accompanying Access File. Access Files are stored as members of a PDS that is allocated to ddname FOCDTCM in the JCL or CLIST used to run FOCUS. Every user of the Datacom Data Adapter must have access to this library, which was not created during FOCUS installation.
Using your site criteria, allocate a partitioned data set (PDS) for your Access Files. This library (or libraries) can be a mirror image of ddname MASTER and should have the same DCB parameters. Refer to your FOCUS MVS/TSO installation guide for assistance in selecting DCB parameters. Two suggested names for this data set are:
prefix.ACCESS.DATA or
prefix.FOCDTCM.DATA
FOCUS error messages are stored as member of a PDS that is allocated to ddname ERRORS in the JCL or CLIST used to run FOCUS. This library was created during FOCUS installation. Every user of the Datacom Data Adapter must have access to this library.
Copy member FOCDTCM of the prefix.DATACOM.DATA PDS to the library each user allocates to ddname ERRORS.
If the ERRORS library is not accessible or is not allocated, error conditions encountered during a FOCUS session or batch job may generate the following message:
(FOC000) ERROR MESSAGE TEXT MISSING
