Oracle Exam 1Z0-133 Topic 7 Question 103 Discussion

Actual exam question for Oracle's 1Z0-133 exam

Question #: 103
Topic #: 7

One of your applications sends SQL requests to a back-end database. Today some of these requests are very slow to complete and users are waiting an unusually long time before getting the information back. You decided to take a look at a thread dump and found several threads with a stack similar to:

What should be your initial assumption and first action?

AThe maximum capacity of the connection pool was reached due to higher load than usual and you just need to wait until new connections get released or increase the capacity of the pool. This can be done in the Admin Console.

BThe response data provided by the database SQL is larger than the receive socket buffer, so you just need to increase the buffer

CThe activity on the database side needs to be checked with your DBA to verify if the connection request was received and how it's been handled by the database

DThe datasource connection was leaked and needs to be reset

EA firewall is blocking the connection between WebLogic Server and the back-end database. This needs to be immediately addressed with your network administrator

FThe Oracle JDBC driver got corrupted and needs to be reinstalled or replaces with a different driver

Woah, a thread dump? This is getting technical. I'm just going to close my eyes and point at one of these options. Eeny, meeny, miny, moe...

I believe we should also check with the DBA to verify the activity on the database side. It could be a problem there as well.

The Oracle JDBC driver got corrupted? That's a new one. I'm not sure I buy that, but it's worth a shot if nothing else works.

I agree with Cassie. We should either wait for new connections to get released or increase the capacity of the pool.

Haha, a firewall issue? That would be too easy. I'm betting on a connection leak, let's go with option D and reset that datasource!

Let's go ahead and reset the datasource then. Hopefully, that will solve the slow SQL requests.

I've seen similar issues before, resetting the datasource usually does the trick.

Yeah, that stack trace does look like a connection leak. Resetting the datasource should help.

I agree, a connection leak seems more likely. Let's go with option D and reset the datasource.

Interesting, I was thinking it could be a socket buffer problem. But option B doesn't seem quite right, better check with the DBA first.

Hmm, this looks like a connection pool issue. I'd go with option A and check the capacity of the pool in the Admin Console.

If the pool capacity is reached, increasing it or waiting for new connections to be released could help resolve the issue.

I think we should also consider checking with the DBA to see how the connection request is being handled on the database side.

I think the initial assumption should be that the maximum capacity of the connection pool was reached due to higher load than usual.
