Find Root Cause Why Database Unresponsive
Apr 30, 2013
We have a 2 node RAC runing on 11.2.0.2 and last night the database was totally un-responsive. when i checked the ADDM I noticed the following:
Waiting for event "cursor: pin S wait on X" in wait class "Concurrency" accounted for 98% of the database time spent in processing the SQL statement with SQL_ID "4b2epo0eaqol9".I am wondering what option do i have here? i am looking to do the following:
1) find the root cause why the database was un-responsive
2) ADDM is listing the query, what options do we have further?

I am trying to correct NMO NOT SETUID-ROOT (UNIX-ONLY) error. On production database (9..7). Googlng this error - it says to run root.sh as root. should this be run in /usr/local/bin. which is the default location.
I don't believe that there would be any problems - but would like some confirmation -to be safe.

I'm having issues with users logging into Oracle. I installed it on Ubuntu 12.04 running Oracle 11.2 XE. If i am root, i can run sqlplus just fine and log in. But when I use a regular user account and run sqlplus, it will just stay blank. No error messages or any feedback. I echo $ORACLE_HOME and echo $ORACLE_SID and they come back exactly as they do under the root account. My path is set up just like root has it.
It almost seems like a permission issue but even when i try sqlplus /nolog it stays blank.

I am studying a way to block the access from the root(UNIX) or admin(WIN) users to the database.
Are there some way to block the access by the superusers?

Because of this output, when see the ./crsctl stat res -t , it showing LISTENER offline for perflahp03, and I can not see any status line for "perflabhp03-vip " and "Scan-listener".
Do I need to reinstall the entire cluster setup because of VIP issue?

We have Oracle ASM and installing 11.1.0.6 on a new machine (eventually will apply 11.1.0.7 patchset). So we are on 11g R1 in production environments.
When installing Oracle ASM 11.1.0.6, the root.sh fails
I checked various metalink notes, all settings are OK. We have ASMLib and i have configured ASMLib with the new disks prior to the ASM installation
Just to rule out the rootcause is with ASMLib , I have also disabled it. Still same problem. I ran the usual localconfig delete and localconfig add too.
Startup will be queued to init within 30 seconds.
Checking the status of new Oracle init process...
Expecting the CRS daemons to be up within 600 seconds.
Giving up: Oracle CSS stack appears NOT to be running.+
Oracle CSS service would not start as installed+
Automatic Storage Management(ASM) cannot be used until Oracle CSS service is started+

How do you find the youngest user in a certain table
select a.illness_desc
from uma.pc_illness a, uma.pc_patient b, uma.pc_diagnosis c
where b.patient_no = c.patient_no and c.illness_code = a.illness_code
and b.age = '21';
i currently have this (it also needs to display their illness which i have done) but i can do only if i cheat and see what the youngest user is, so instead of b.age = 21 i need something that will search the database and find that youngest age
we are using SQL+

There is one DBMSJOB i created schedule to run every day at 22:00 hrs. The jobname is IT_TO_DUM_LOADING and the job type is Stored procedure.
I queried all_source and found stored procedure does not exist in database.
SQL> select text from all_source
2 where type = 'PROCEDURE'
3 and name ='IT_TO_DUM_LOADING';
no rows selected
But i could see the job details in dba_scheduler_jobs view. I cannot use WHERE clause in dba_scheduler_jobs to restrict and find only the job row as i receive time zone error. How it is possible to view the job in dba_scheduler job view whereas i could not find the stored procedure of its in all_source?
