Cursor Pin S Wait For X In 11g Enterprise Edition Release 11.2.0.2.0
Sep 4, 2013
Ours is Oracle 11.2.0.2.0 Db 4 instances RAC on Unix AIX OS.Since long we are facing problem that CPU utilization reached 100% and reboot is required alteast once or twice a month.On seeing the Events Logs we find that the Event "CURSOR PIN S WAIT FOR X" is consuming a lot of waits.
On analyzing i came to know that we are firing same query from Application 15 to 20 lack times for which a lot of Mutex keeps spining for getting Shared Mode and consumes a large amount of CPU.

The only supported technique for converting an EE database to SE is export-inport, as documented in note 139642.1. Our client is reluctant to do this because of the downtime involved. It is however possible to open the EE database from an SE home, no problem.
The note says only Quote:When you just install the Standard Edition software, you will end up with Data Dictionary objects which are of no use (or perhaps even invalid) and possibly create problems when maintaining the database.

In our environment we have db link to fetch data from other database. Whenever we try to fetch data using the dblink we receive the wait event "cursor: pin S wait on X" and we do not get any result. The db link works fine. what could be the issue.
DB Version : 11.1.0.7 OS: AIX

I am checking out licenses. We all know that EE is much more expensive than SE. But many customers do have EE installed - unsure if they need all the features at all. After several years of production, a downgrade is considered 'risky' and we continue to pay the full EE.
How can we check and be sure that a downgrade to SE would not be any problem?
Some checks include:
* partitioning used in user schemas? --> no downgrade to EE
* bitmap indexes in user schemas? --> no downgrade to EE
How can we complete this list, or is there some script to make this easy?

I am querying v$sga and getting variable size : 211337216 bytes.when querying v$sgastat then getting
java Pool : 16777216
Large Pool : 41943040
Shared pool : 398560392
But as per my knowledge following condition should satisfy,but not getting
[code]
Variable sga = java pool + large pool + shared pool
select pool,name,sum(bytes)
from v$sgastat
where pool in ('shared pool','java pool','large pool')
group by pool,name;
Here variable size using v$sga : 211337216 bytes
and java pool + large pool + shared pool : 211302536 bytes.
[/code]
but it should match?

In our current setup we have RAC on standard edition and client is now planning to go for Enterprise Edition but not yet decide because of cost. Is there any difference between Grid Infrastructure 11gR3 Enterprise edition and Standard Edition ?
They told me to first install Enterprise Edition and then will move to Standard Edition if they can't get the EE license so in that case do i have to re-install Grid infrastructure for standard edition?

I am trying to look at wait events for a long running query in TOAD.I start the query on one instance of TOAD and open the Session Browser on another instance.But I am surprised to find that in "TOtal Waits" on the RHS-> SQL*Net message from client is the longest time taking and is already -> 178577 units whereas I have just started the query.
Whereas in the Current Waits it shows DB File Scattered Read currectly as some seconds.

We have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36%
Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.

We are using the following statement to obtain a row lock in a table in the database(ORACLE 10G), SELECT * FROM {TABLE_NAME} WHERE ID = 1 for update and if we succeed grabbing the row lock we will continue to issue a update statement every 30 seconds to preserve the lock as far as possible. here is the update statement to preserve the lock,
UPDATE {TABLE_NAME} SET time = ? WHERE ID = 1.
As you see more longer we keep holding the row lock , more update statements are submitted in the pending transaction. In normal case our application can grab the exclusive row lock and works for a long time,however sometimes a connection reset exception is thrown and our application will close the connection(I assume the pending transaction will be rolled back by the database) and exit the JVM. Since other applications will keep trying to grab the same row lock to become the master role, we expect one of them can succeed but they are all failed because the database has not released the row lock as expected. how and when the row lock can get released in our use case?

Its was sucessfully created and my_ts.dbf file has 5MB
charging with data...
CODEcreate table big_table tablespace my_ts as select * from dba_objects;
select * from big_table;

for i in 1..10 loop
insert into big_table select * from dba_objects;

assuption is that when we truncate the partition it immediatly release the allocatd storage.i have just tested the scenario , but still i can see that table size is same even after truncating the partition( which have around 25% of the data)
alter table test truncate partition t1p3 update indexes ;
OR
alter table test truncate partition t1p3 drop storage update indexes ; to see the table size:
SELECT owner, table_name, TRUNC(sum(bytes) / 1024 / 1024) Meg
FROM (SELECT segment_name table_name, owner, bytes
FROM dba_segments
WHERE segment_type = 'TABLE'
UNION ALL

we need to find the key pressed action and key release action on Oracle form 10g. On key pressed (i.e. key-up, key-down, key-page-up and key- page-down) the event will be fired and as soon as the user release the key, the event will be stop.
As current situation, we have one form which contains the database blocks. As per search condition, all the data populated in Database block, there are 1000 and more records. Now user going use any of key (i.e. key-up, key-down, key-page-up and key-page-down) as he pressed key ( say Key- down) it scrolled down but as soon as he release the key, the event is not stopped. its going on going down then stop.
Is it possible, as user release the key scrolling will stopped at same time ?

Tried to use the yum command "yum install gcc" but get the following error.

I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,create public database link using 'orcl';then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.
