BB站台連線異常

Q: BB站台連線異常是的錯誤訊息ORA-00018: maximum number of sessions exceeded

A: 超出session最大值~可試試再增加oracle的process和session參數

原廠建議調校數據如下，請查照

I. Database changes

---

\*max number of semaphore identifiers: set semsys:seminfo_semmni=50 \* \*max number of semaphores per identifier: \*semmsl=largest number of processes of all instances < 512 set semsys:seminfo_semmsl=500 \* \*max number of semaphores: semmns=semmni*semmsl \*semmns>=sum of all processes of all instances \*semmns>=semmni*semmsl set semsys:seminfo_semmns=25000 set semsys:seminfo_semopm=100 set semsys:seminfo_semvmx=32767

II. Appserver changes \********************* bbconfig.unix.httpd.maxclients= 200 bbconfig.appserver.maxthreads= 200 bbconfig.database.bb_60.db.maxpoolsize= 200 bbconfig.database.bb_60.db.minpoolsize= 50 bbconfig.max.heapsize.tomcat= 1024m bbconfig.min.heapsize.tomcat= 512m bbconfig.unix.modperl.keepalive= Off bbconfig.unix.modperl.maxclients= 20 bbconfig.unix.modperl.maxspareservers= 10 bbconfig.unix.modperl.minspareservers= 3 (or 5) bbconfig.unix.modperl.startservers= 10 bbconfig.unix.httpd.maxspareservers= 50 bbconfig.unix.httpd.minspareservers= 10 bbconfig.unix.httpd.startservers= 50

另外原廠也建議，如果之後使用上遇到java.long.OutOfMemory error，可以把bbconfig.max.heapsize.tomcat= 1024m 改成1280m 或是1536m
