Does oracle log general errors

Question

Dear experts,
I am using Oracle 11.2.0.3. I am researching on random ORA-00900:     invalid SQL statement error that we are seeing in production. Does oracle log such errors in alert.log or any tables? If not can we configure to log such errors?
Thanks.

Dont understand.... you are seeing ORA-00900 in production but don't know where to search this error? where do you see it?It is being logged from application in event log which I do not have access to. I wanted to check if oracle also logs such error some where.
