I have a RAC on 9i and I want to know the number of active sessions that it's executing the same sql sentence.I'm using this sql but I'm not sure that this query give me te correct result.
SELECT se.inst_id,se.status,se.SQL_HASH_VALUE,se.USERNAME,substr(sq.SQL_TEXT,1,50) SQL,count(*)
FROM GV$SESSION se, gv$sql sq
WHERE se.STATUS='ACTIVE'
and se.username is not null

Oracle Database 11g Release 11.2.0.1.0 Standard Edition
I recently applied the Oracle® Database Server Version 11.2.0.1 Patch 16 I have several databases running on this box with the same application.Since then I've had lots of customers complaining about slow systems. The server has plenty of RAM availableI also have several other servers all on the same versions, same patch, running the same application with no issues.
Looking at v$session there are often lots of active sessions that have a sql_address of "00". I've never seen this before and I regularly look at v$session, as you can see for below these have been running for a while. The sessions do drop off but I am at a loss as to what is happening.
select username, last_call_et, sid, serial#, user#, status, sql_address, sql_hash_value
from v$session
where username is not null and status = 'ACTIVE'
order by last_call_et desc, sid
[code]...
We have quite a number of sessions in database MES (production) coming from another machine.
From v$session, the program is oracle@WID27 (TNS V1-V3). This WID27 (hostname) consists of quite a number of development databases inside. We have to trace which jobs are actually triggering this, as WID27 are not suppose to connect to production databases.
How can we tell whether the sessions came in is from dblink or from the machine itself?
I am getting starting with rac environments. I need to configure a two nodes active/active with rac and I need to know if always using rac both nodes will be active or if I have to do that at some point when installing. I have reading some docs from oracle and others authors about rac and its configuration process but that is not understood for my yet.

For example,

I want to tuning the next sql sentence. In this sql I want to get the hash_value and sql_text of the sentences that it's causing TX blocks. Is it possible?. This sentence works fine but sometimes It's slow.
SELECT DISTINCT hash_value,
sql_text
FROM gv$sql sq
WHERE hash_value IN (SELECT DISTINCT prev_hash_value
FROM gv$session se
WHERE sid IN (SELECT sid
FROM gv$lock l
WHERE type = 'TX'
AND ctime >= 2000
AND l.inst_id = se.inst_id
AND l.sid = se.sid)
AND sq.inst_id = se.inst_id);

Is there some way to validate the syntax of sql sentence without actually executing it? I dont want to check if the objects exist or not, just want to check the syntax.

We are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.
I have some strings like
'Net Amount Payable by an Individual',
'Net Amount Payable by an Individual+Tax',
'Total Amount Payable towards Service',
'Total Amount Payable towards Service.+Tax'
I need to extract the first three letters from each word and separate them using an underscore. The output should be as follows for the above strings -
Net_Amo_Pay_by_an_Ind
Net_Amo_Pay_by_an_Ind_Tax
Tot_Amo_Pay_tow_Ser
Tot_Amo_Pay_tow_Ser_Tax
I request to let me know the way to get the ouput as mentioned.
I have set my processes and session value in my database as 1000 and 1248 respectively. I am using 11.2.0.1 but when I restart my DB it showing me sessions=1524...its too high value then what I set.I don't know why it showing higher value than the value I set...
ALTER SYSTEM SET processes=1000 SCOPE=SPFILE;
ALTER SYSTEM SET sessions=1248 SCOPE=SPFILE;

System parameters with non-default values:
processes = 1000
sessions = 1524
And one more thing is there any recommended formula for calculate sessions in 11g? [ I found one formual from google:
SESSIONS derived: (1.1 * PROCESSES) + 5
One of our DB server is high on CPU utilization, as per the AWR we found couple of queries are running many times and taking huge CPU, hence we need to know from which user these queries are runnings.find the session information as per the sql id?
View 9 Replies View RelatedIn our databace there are around 300 sessions were in inactive state.
Database is not releas the sessions.
our db shows more than 200 INACTIVE Sessions ; and the DBA plans to reboot the db to get rid of these sessions . Can we not KILL these sessions and avoid the reboot ?
View 4 Replies View RelatedI'm using Toad 11.6, I can see about 156 sessions for the database in the session browser but when I do a select from v$session, only 40 sessions are showing up. I was able to look at all the sessions until yesterday. I tried several views like v$session, v$open_cursor etc, but only 60 sessions show up. I'm connected to the database using same user login yesterday and this morning.. May be this user had some privileges revoked last night??If so is it possible to limit sessions in these views (v$session etc) but it's strange that I can see them in the session browser in Toad. 'm very confident that there are 156 sessions in the database but it's just that I'm not able to see them in the v$session etc views. I need to troubleshoot a session but it is not showing up in any views.

I want to change the the number of processes to 150 (default is 100) I did this by issuing the below command.
alter system set processes=150 scope=spfile;But why that modified value is not being reflected?
select name, value from v$parameter where name in ('sessions','processes','transactions');
NAME VALUE
-------------------- -----
processes 100
sessions 172
transactions 189
Is there any way to tell what processes/sessions were connected to a DB after I get an ORA 20error. As you can see from the query results below, I did hit the max value of processes but I would like to know when it happen and who was connected.
I realize I can up the value, but before I do that I want to see what caused this to happen.
SQL> select * from v$resource_limit where resource_name in ('sessions', 'processes');
RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL
LIMIT_VALU
----------
processes 221 1000 1000
1000
sessions 223 1020 1105

SESSIONS_PER_USER
Each instance maintains its own SESSIONS_PER_USER count. If SESSIONS_PER_USER is set to 1 for a user, the user can log on to the database more than once as long as each connection is from a different instance.

Of course the following is not working even when resource_limit is TRUE
ALTER PROFILE DEFAULT LIMIT SESSIONS_PER_USER 2;
How can I restrict a user to have limited sessions say 2 sessions across 4 node cluster? Presently I am checking the sessions logged in using sql+ and no connection pooling of front end etc. is involved.

how to avoid oracle deadlock with two sessions. Here is my example, We use Select query with For Update in order to get the unique number from a table. When one user has accessed this query, while the other user tries, System gives a Performace slow and when checked it is due to locking of this select query with For update.
We don't want to use For update WAIT or FOR UPDATE NOWAIT since these will result in missing of number.
why are there in the Administration --> --> Session 2 entries for 1 database connection (here with benthic golden).But if I login in a browser, there is only 1 entry for this database connection

On the oracle 11g, we see too many invalid sessions. Because of which, login is getting restricted. What do i need to do to kill those invalid session periodically, which will avoid of restarting of system.

I need to identify, whether my current session is one of slave sessions scheduled as Oracle scheduler job via DBMS_PARALLEL_EXECUTE or not. I already succeeded using join of dba_scheduler_running_jobs, user_parallel_execute_chunks and v$session, but I feel that this is not optimal approach.
