IBM RS/6000, AIX4.1.5, and DS7.23

Has anyone experienced memory problems with running Online DS7.23 on a PowerPC based RS/6000 (2 CPUs) with AIX 4.1.5 as the OS 256MB physical and 448MB paging? We seem to experience a major slow-down in system performance which seems to be related to quite a bit of memory swapping. Here are some of the onconfig params: LOCKS 10000 # Maximum number of locks BUFFERS 400 # Maximum number of shared buffers NUMAIOVPS # Number of IO vps PHYSBUFF 64 # Physical log buffer size (Kbytes) LOGBUFF 128 # Logical log buffer size (Kbytes)LOGSMAX 16 # Maximum number of logical log files CLEANERS 6 # Number of buffer cleaner processes SHMBASE 0x30000000L # Shared memory base address SHMVIRTSIZE 32768 # initial virtual shared memory segmentsize SHMADD 8192 # Size of new shared memory segments (Kbytes) SHMTOTAL 0 # Total shared memory (Kbytes). 0=>unlimited CKPTINTVL 300 # Check point interval (in sec) LRUS 8 # Number of LRU queues LRU_MAX_DIRTY 50 # LRU percent dirty begin cleaning limit LRU_MIN_DIRTY 20 # LRU percent dirty end cleaning limit LTXHWM 50 # Long transaction high water markpercentage LTXEHWM 60 # Long transaction high water mark (exclusive) TXTIMEOUT 300 # Transaction timeout (in sec) STACKSIZE 32 # Stack size (Kbytes) -- Greg Krasnow HNC Software Inc.
