·SEMMSL: Maximum number of semaphores per semaphore sets (Not defined in NT). Use the formula: SEMMNS = SEMMNI * SEMMSL
·SEMMAP: Size of the control map used to control semaphore sets (Not defined in NT). Set to SEMMNI
·SEMMNU: Number of undo structures in the system. Set to SEMMNS
·SEMUME: Maximum number of undo entries per undo structure (Not defined in NT). Set to SEMMNSShared Memory Parameters·SHMMAX: Maximum shared memory segment size in bytes. Bulletin Board Size (must be greater than 1,400,000). Largest BB today is approx. 5 MB (this parameter is normally set much higher for the database, so use their rules)
·SHMSEG: Maximum number of segments one process can attach to (for a busy application you need to set this from 32-64)
·SHMMNI: Maximum number of shared memory identifiers in the system. Normally the default of 100 is acceptable (unless more than 100 entities plan on allocating shared memory)
·SHMMIN: Minimum shared memory segment size in bytes. MUST be set to 1.Other Tunables·ULIMIT: Maximum file size. ULIMIT needs to be large enough so that you can install BEA TUXEDO and build servers. 4 megabytes recommended.
·MAXUP: Maximum number of processes per non-super user. The BEATUXEDO system processes--servers and administrative processes—runwith the UID specified in the application's UBBCONFIG file. MAXUP needsto be large enough to allow all of these processes to run.
·NOFILES: Maximum number of open files per process. A BEA TUXEDO server requires a minimum of four file descriptors.
