where:

fileid

In CMS, is the file name, file type, and file mode of the FOCUS data source accessed by the disconnected virtual machine (FOCUS Database Server).

In z/OS, is lthe ddname of the FOCUS data source allocated in the batch job or started task.

To use the EMPLOYEE FOCUS data source on the A-disk of the FOCUS Database Server named myserver, code the following:

USE
EMPLOYEE FOCUS A ON MYSERVER
END

To use the EMPLOYEE FOCUS data source allocated to the FOCUS Database Server batch job or started task, two things must be done:

1. Allocate a ddname to the communications data set that is allocated in the FOCUS Database Server batch job or started task pointed to by the ddname FOCSU.

   For example,

   DYNAM ALLOC FILE MYSERVER DS prefix.FOCSU.DATA SHR

2. Issue the USE command for your data source allocated in the batch job or started task. For example:

   USE
   EMPLOYEE ON MYSERVER
   END

Performance gains may be achieved by routing read-only requests directly to the data source on disk instead of through the FOCUS Database Server. This is called a multi-thread configuration. It is accomplished with the USE command and the keyword LOCAL.
