Security Services Implemented Within Oracle HTTP Server

8-20 Oracle HTTP Server Administrator’s Guide

SSLMutex Type of semaphore (lock) for SSL engine’s mutual exclusion of

operations that have to be synchronized between Oracle HTTP Server processes.

Category Value

Valid Values ■ none: Uses no mutex at all. Not recommended, because the mutex

synchronizes the write access to the SSL session cache. If you do not

conﬁgure a mutex, the session cache can become garbled.

■ file:path/to/mutex: Uses a ﬁle for locking. The process ID

(PID) of the Oracle HTTP Server parent process is appended to the

ﬁlename to ensure uniqueness. If the ﬁlename does not begin with a

slash (/), it is assumed to be relative to ServerRoot. This setting is

not available on Windows.

■ sem: Uses an operating system semaphore to synchronize writes. On

UNIX, it would be a Sys V IPC semaphore; on Windows, it is a

Windows Mutex. This is the best choice, if the operating system

supports it.
