HP-UX Kernel Configuration for Oracle for 8i/9i (3)
第三部分
SEMVMX |
Maximum value of a semaphore. Recommended: >= Oracle 9i = 32768
|
shmmax (see appendix 4) |
maximum allowable size of one shared memory segment. The SHMMAX setting should be large enough to hold the entire SGA in one shared memory segment. A low setting can cause creation of multiple shared memory segments which may lead to performance degradation, but normally it is ok to use a small number of shared memory segments.
default=0x04000000 (64MB) Oracle 7 0x40000000 (1GB = 1073741824 Bytes) Oracle 8, 8i, 9i recommended: db_block_size * db_block_buffers + shared_pool_size + log_buffer + shared memory for the application or hold the entire SGA in one shared memory segment ! (for 64bit use up to size of physical memory, but Oracle can also use multiple segments (please check appendix 4))
|
Shmmni |
maximum number of shared memory segments in the entire system. default=200. recommended: <= Oracle 8.1.7 = use default. >= Oracle 9i = 512
|
Shmseg |
maximum number of shared memory segments one process can attach. default=12. recommended: <= Oracle 8.1.7 = 10 per Oracle database >= Oracle 9i = 32 per Oracle database
|
Streampipes |
Set this parameter to 0 during on the installation of Oracle DB will reduce the installation time. Default: 0 Recommended for installation: 0 |
swapmem_on (see appendix 5) |
Allow Memory to Exceed Swap Spacedefault: 0 (off) recommended: 1 (on)
|
Swchunk |
Swap Chunk Size (1K Blocks) (related to kernel parameter maxswapchunks) default: 2048 recommended: 4096 (up to 65536 for large RAM)
|
VPS_CEILING |
maximum System-Selected Page Size in kilobytes. Recommended: >= Oracle9i = 64 (up to 16384 = 16MB for large SGA)
