Specifying the file sharing (SHARE) parameter when creating a database file

The database system lets multiple users access and change a file at the same time. 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 a file's status, record position, and buffer. Sharing files in a job can improve performance by reducing:

• The amount of storage the job needs.
• The time required to open and close the file.
