Element | Required | Description

property (with attributes) | zero or more | Specifies a property, which has a name and a value.

### Properties

The following table describes properties for the `manager-properties` element.

Table A–62 `manager-properties` Properties

Property | Default | Description
--- | --- | ---
`reapIntervalSeconds` | `60` | Specifies the number of seconds between checks for expired sessions. This is also the interval at which sessions are passivated if `maxSessions` is exceeded. To prevent data inconsistency, set this value lower than the frequency at which session data changes. For example, this value should be as low as possible (`1` second) for a hit counter servlet on a frequently accessed web site, or the last few hits might be lost each time the server is restarted. Applicable only if the `persistence-type` attribute of the parent session-manager element is `file`.
`maxSessions` | `-1` | Specifies the maximum number of sessions that are permitted in the cache, or `-1` for no limit. After this, an attempt to create a new session causes an `IllegalStateException` to be thrown. The session manager passivates sessions to the persistent store when this maximum is reached. Applicable only if the `persistence-type` attribute of the parent session-manager element is `file`.
`sessionFilename` | none; state is not preserved across restarts | Specifies the absolute or relative path to the directory in which the session state is preserved between application restarts, if preserving the state is possible. A relative path is relative to the temporary directory for this web application. Applicable only if the `persistence-type` attribute of the parent session-manager element is `memory`.
