3.84. SessionType
The type of session management to be used. Use one of the following:
DB_File Berkeley DB DBI DBI (don't use this, normally) File File-based sessions (the default) NFS File-based sessions, forces use of fcntl locking GDBM GDBM
The default is file-based sessions, which provides the best performance and reliability in most environments.
If you are planning on running Interchange servers with an NFS-mounted filesystem as the session target, you must set SessionType to "NFS". The other requisites are usually:
1. fcntl() supported in Perl 2. lock daemon running on NFS server system 3. lock daemon running on Interchange server
See also the global directive LockType.
