On UNIX, provides a way for the operating system to limit file access to only one process (user).
Note:  | This setting does not apply to Windows systems.  | 
FILELOCKINGMODE Advisory | Mandatory | None
Advisory—Locks files. All applications that follow rules (like Essbase) will honor the locks. This is the default setting.
Note:  | When FAILOVERMODE is set to TRUE, setting FILELOCKINGMODE to Advisory or Mandatory has no effect.  | 
Mandatory—Locks files at the kernel level. This setting provides extra security to protect against malicious software.
None—No files are locked. Two Essbase instances can modify the same data and potentially corrupt it. This option is added for Failover mode where file access is not done by the operating system, but by an application acquiring a lease (use database).
FILELOCKINGMODE specifies how files are locked on UNIX systems.
