One question about connection pool busy problem

edited Dec 21, 2010 2:52PM in Database Administration (MOSC) 8 commentsAnswered ✓
 Hi All,

My case is: I created connection pool with 500 connections in Java middler tier. Users can grab them and when they have finished the task, they release the connection for other's use.

But after some time, the contention of connections happened. Some uses must wait for the availablity of the connections. But at this time, I checked the database and only found less than 300 sessions.

At the same time, another applicaiton that shares the same instance encountered ora-12500 error.

Can anybody give me some tips on this issue,please?

best regards,

Leon
