HighestFileNumber

Integer

2048

Purpose

The HighestFileNumber parameter specifies the maximum number of transient overflow files that can be opened on the node; that is, it imposes an upper limit of the number of processes that can run on the node. This parameter corresponds closely to the FileNumberHeadroom parameter in the [PersistentDb] section.

The highest database file number cannot be greater than 65,483.

Parameter is read when …

The node is initialized.

Hint

If you anticipate that you will execute more than 2,047 processes on a node, increase this value so that you do not have to restart the node. (Exception 3003 is raised when the number of active processes exceeds this value.)
