-> SessionNoServer
Parameters
- systemDir
- Type: SystemString
The startup location directory path. Path can be an absolute (full) path or a path relative to s_baseDatabasePath - waitForLockMilliseconds (Optional)
- Type: SystemInt32
The desired maximum lock wait time - optimisticLocking (Optional)
- Type: SystemBoolean
Use optimistic locking. With optimistic locking, readers are always permitted and multiple updaters are permitted to update the same Databases/Pages but only the first transaction to commit or flush an updated Database/Page will be successful in making the commited chane. Other updaters will get an OptimisticLockingException if they try to commit/flush updates to the same Pages/Database.
See http://en.wikipedia.org/wiki/Optimistic_concurrency_control for further explanation of optimistic locking. If optimistic locking is not enabled then pessimistic locking is used. See: http://en.wikipedia.org/wiki/Concurrency_control - enablePageCache (Optional)
- Type: SystemBoolean
If strong reference page caching isn't desired, turn it off by setting to false - objectCachingDefaultPolicy (Optional)
- Type: VelocityDbCacheEnum
Determines default value of Cache - enableDatabaseCache (Optional)
- Type: SystemBoolean
Is this session going to enable strong reference Database caching?
