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
