Specifying the share open data path (SHARE) parameter

 

The system allows multiple users to access and change a database file at the same time. The SHARE parameter specifies whether the open data path (ODP) is shared with other programs in the same routing step. The SHARE parameter allows sharing of opened files in the same job. For example, sharing a file in a job allows programs in the job to share the file's status, record position, and buffer. The file sharing can improve performance by reducing:

• The amount of storage the job needs.

• The time required to open and close the file.
