DS 7.23 performance

We have upgraded from Online 5.06 to Dynamic Server 7.23.FC1 on OSF1 ver 4.0 and have major performance problems. Some applications now are up to 6 times slower. Applications also once in a while receives error -25587 and -25588. I've tried to increase LOCKS and BUFFERS, but then receives: oninit: Fatal error in shared memory creation ...and in the online.log: 17:21:26 shmat: [ENOMEM][12]: out of available data space, check system MAXMEM 17:21:26 mt_shm_init: can't create virtual segment Increasing SHMVIRTSIZE causes: 13:13:10 shmat: [EINVAL][22]: shared memory base address illegal 13:13:10 using 0x2025ce000, needs 0x800000 13:13:10 mt_shm_init: can't create virtual segment ONCONFIG-PARAMETERS: SERVERNUM 0 # Unique id corresponding to a OnLine instance DBSERVERNAME ebba_on DBSERVERALIASES t2000 # List of alternate dbservernames NETTYPE ipcshm,,,CPU # Configure poll thread(s) for nettype NETTYPE soctcp,,,NET # Configure poll thread(s) for nettype DEADLOCK_TIMEOUT 60 # Max time to wait of lock in distributed env.
