Hi All, Currently we have a very large database ( 8.1.7.4 ) on Tru64 that is having query optimization problems. Lacking good, up-to-date statistics is the main cause of it. Because of the size and availability window we can't afford to analyze the whole schema. Now 8i has a new feature that only gathers stats when stale. You have to set table to monitoring mode first. I am intrigued by this new feature and am reading up on it and have 2 questions: 1. How reliable and bug-free is this feature? 2. We do a lot of sqlldr direct path, which bypasses table insert. Will this feature catch the rows inserted that way?
TIA Dennis -----Original Message----- Sent: Friday, June 27, 2003 2:30 PM To: Multiple recipients of list ORACLE-L One of our third party applications gave us the following message: ORA-04031: unable to allocate 4192 bytes of shared memory Environment is Oracle 8.1.7 on AIX 4.3.2 The output from "select * from v$sgastat showed about 3 mb free out of a total of 40 mb of shared pool. I increased the size of shared pool to 60 mb and started to watch the "shared pool"/"free memory" value in v$sgastat. It seems to vary between about 3 and 11 mb. 1. What is the application likely to be doing that requires it to allocate shared pool? 2. How do I know when I have the shared pool value in init.ora set high enough so that I won't get the ORA-04031 errors? 3. Is there any other init.ora parameter I ought to be looking at here?
