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，經過討論 oracle process 改為500。
其他參數由原廠建議調校數據如下
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
