BEA Weblogic performance issue

Question

Hi All,
We are using bea weblogic 10.2.
We have some performance issue in our production.
We face the proble like
1. Our bea query takes maxixmum cpu utilization in the oracle databse.
process are content upload, update, expiry and report fetching.
2. When we run BEA query for report it takes around 10 min to run and content count is around 70,000,
is this OK?
3. Some times we get Socket connection error.
4. Sometimes we get portal datasource connection pool error, currently it is set as 30.
5. Almost every process is slow.
Can anyone help me for optimization?
From BBA,
we idetified the query which is taking high CPU utilization..
SELECT
DISTINCT B.NODE_ID, B.NODE_VERSION_ID, B.CM_MODIFIED_DATE, B.MODIFIED_BY,B.VERSION_COMMENT,
B.LIFECYCLE_STATUS,A.OBJECT_CLASS_ID,A.REPOSITORY_NAME
FROM CMV_NODE A, CMV_NODE_VERSION B,(SELECT NODE_ID, MAX(CAST(NODE_VERSION_ID AS INTEGER)) NVI
FROM CMV_NODE_VERSION GROUP BY NODE_ID) A1, ( SELECT B.NODE_ID,B.NODE_VERSION_ID, B.CM_MODIFIED_DATE,
B.MODIFIED_BY, B.VERSION_COMMENT, B.LIFECYCLE_STATUS, A.OBJECT_CLASS_ID, A.REPOSITORY_NAME FROM CMV_NODE A,
CMV_NODE_VERSION B, CMV_NODE_VERSION_PROPERTY N1, CMV_PROPERTY P1, CMV_VALUE_V V1 WHERE A.NODE_ID = B.NODE_ID
AND B.NODE_ID = N1.NODE_ID AND B.NODE_VERSION_ID = N1.NODE_VERSION_ID AND N1.PROPERTY_ID = P1.PROPERTY_ID
AND P1.PROPERTY_ID = V1.PROPERTY_ID AND P1.PROPERTY_NAME = :1 AND (UPPER(V1.TEXT_VALUE) LIKE :2 ESCAPE :"SYS_B_0" )
UNION
     SELECT B.NODE_ID, B.NODE_VERSION_ID, B.CM_MODIFIED_DATE, B.MODIFIED_BY, B.VERSION_COMMENT,
B.LIFECYCLE_STATUS, A.OBJECT_CLASS_ID, A.REPOSITORY_NAME FROM CMV_NODE A, CMV_NODE_VERSION B, CMV_NODE_

Answer 1

If your DB CPU is pegged, then anything that does db operations will take time (including some portal operations). If you take a thread dump you should be able to see them waiting on the DB
When we run BEA query for report it takes around 10 min to run and content count is around 70,000,No. If it causes your CPU to max out it isnt. However your content items arent that much, so what query are you running? You could always export and import just the content tables and run your queries on some other machine (Assuming this is the cause)
3. Some times we get Socket connection error.More information needed
4. Sometimes we get portal datasource connection pool error, currently it is set as 30.What is the error?
5. Almost every process is slow.If the DB is maxed this is what you should expect.
When is the query fired? Are your indexes created? I assume caching is not much good to you since these are reporting queries?
