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

bbconfig.database.bb_60.db.minpoolsize= 50

bbconfig.unix.httpd.maxspareservers= 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
