Parameter key options for the FILESYSTYPE statement

The parameter key options for the FILESYSTYPE statement are as follows:

-ea count

Allows the TFS file system to automatically grow count times. The TFS grows 1 K blocks each time it grows. For the default 4 K block size, the TFS grows 4 MB. The extension occurs when the file system fills up, before the file system full message. When specified, this option overrides the TFS default setting.

Restriction: The sum of auto-extend and manual extend cannot exceed 500.

-em count

Allows the TFS file system to manually grow count times. The TFS grows 1 K blocks each time it grows. For the default 4 K block size, the TFS grows 4 MB. If -em is specified, any excess block allocation space is added to count. When specified, this option overrides the TFS default setting.

Restriction: The sum of auto-extend and manual extend cannot exceed 500.

-fsfull(threshold,increment)

Sets FSFULL monitoring to the specified values. When specified, this option overrides the default setting.

threshold is a number in the range 1-99. When the temporary file system is threshold percent full , a message is issued.
increment is a number in the range 1-99. When the temporary file system becomes increment full or empty, any threshold messages that were previously issued is deleted.

-fsfull can be specified in uppercase or lowercase.
