As per this we predicate Logbuffer Might be full so i just to reboot server,Note server was 32 Bit i can allocate only 1GB of SGA SYStem not allows me to increase SGA further. Server reboot is proper solution?
I want to know the DATE, LOG SEQUENCE NUMBER which was applied in the Standby (DR)one year before.
I am not able to get through "v$log_history".
While creating the index we are getting the error "ORA-00603: ORACLE server session terminated by fatal error".
We have the space in tablespaces and also in the file systesm.
we have a software which keeps a check on v$session table so that a client can not have more than one sessions running simultaneously with the server. But if a client program terminates unexpectedl, it's session information stays in the v$session table, which prevents us from opening a new instance of the client program. Using
ALTER SYSTEM KILL SESSION 'SID, SERIAL#'
doesn't work since it takes ages to rollback and release the locks. And the session stays there with a 'KILLED' status.I want this session out of the v$session table and instantly.
My disk is completely full so i decided to drop temporary tablespace and create a new one but unfortunately the query to drop temp tablespace hang in between to whic I come to know that there were some sessions which were using it for sort purpose.
check out the queries below with results:
SQL> SELECT b.tablespace,b.segfile#,b.segblk#,b.blocks,a.sid,a.serial#,
2 a.username,a.osuser, a.status
3 FROM v$session a,v$sort_usage b
4 WHERE a.saddr = b.session_addr;
[code]....
Was able to killed three of the four sessions but not the last one.
I would like to log session activities. I would also like to be able to check if the session for which an activity has been logged is still active. The problem is, what do I need to uniquely identify a session?
DBMS_SESSION.UNIQUE_SESSION_ID - is explained as: unique for all sessions currently connected to this database. Meaning that if I restart the DB or connections are closed and opened, it might not be unique anymore, right?
SYS_CONTEXT('userenv','sessionid') - returns AUDSID, but is this guarantied to be unique and not been reused, forever? What I do not want to happen is, that I use a session identifier, which might reappear.
My best guess is currently:
SYS_CONTEXT('userenv','sessionid') + logon_time (from V$SESSION)
This combination should be really unique and should never reappear, right?
I need to ask about PGA memory. Is this memory for every user or every session
i.e. PGA 200M
I have 2 users with 300 connection with one of them. Is 200M for 300 connection or for every connect.
when I was analyzing high CPU utilization issue, I saw that the most of the top PID's were INACTIVE in database. But it was utilizing more than 4% CPU. how it is utilizing CPU without doing any work in database?

One user complained that, his session is closing automatically when his session exceeds exactly 01 hour 1 minute.
default profile is assigned for this user. I checked the idle_time value of this default profile. it is UNLIMITED only. What else I need to check to find out is there any timeout parameter has been set or not?
Which is the best way to kill a session?
alter system kill session sid,serail#
or
kill -9 spid
or
orakill sid,thread
I am using unix,windows operating system.
How to kill of a killed session?
I had killed inactive session using alter system kill session 'sid,serial#';
after that that sessions marked as killed and still get in v$session.
Then i try to get spid so that i can killed then from os command kill -9 spid
but when i try to get that join with v$process, no row select.
select * from v$session where username ='CAS' and status ='KILLED'
return 205 records.
select p.*,s.username,s.program,s.machine,s.status from v$process p,v$session s
where p.addr=s.paddr and s.status='KILLED'
return no record.
what does 'SNIPED' status in v$session mean? It is killed/ clear from instance automatically or need to kill manually for releasing the resource.
View 3 Replies View RelatedI am using TOAD to monitor user sessions. I have a user who uses nearly 80% of Overall resources in the mornings. He calls me daily and say that his work is done. But even then the TOAD shows that he is using same resources for some time.
My question is can i kill the session once he confirms his work is done OR do i need to wait till the redologs are cleared.
A way to show session parameters? Such as
CONSTRAINTS
USE_STORED_OUTLINES
ROW ARCHIVE VISIBILITY
CURRENT_SCHEMA
I can detect the CURRENT_SCHEMA with a query against the user env context, but I can't find any of the others there. Could there be an issue with these values being stored in PGA, and therefore not visible though any regular views? I did find an article that showed a query against an x$ data structure which showed something for different settings of CONSTRAINTS, but I can't find it again.
when i modify a column of table tb_hxl_user,just as flowing:
Alter Table TB_HXL_USER Modify CREATE_DATE Not Null
now i select the table TB_HXL_USER,just as flowing:
select * from TB_HXL_USER;
it is hang,and i found the wait event is library cache lock in v$session_waits,why?how can i avoid this.

I am using 10.2.0.4 oracle database on Solaris 10. We are running some Peoplesoft upgrade on one of the database from last 6-7 hours. The status of the session is INACTIVE from couple of hours. And the sql_id is null for these sessions.
select sid,serial#,STATUS,to_char(logon_time,'DD-MON_YY HH24:MI:SS') from v$session where username like '%&usern%' ORDER BY 4 DESC;
533 2234 INACTIVE 04-MAR_10 01:59:02
525 5919 ACTIVE 04-MAR_10 01:54:50
534 4186 INACTIVE 04-MAR_10 01:05:15
520 2320 INACTIVE 04-MAR_10 00:29:44
[code].....
While when i see the current sql from the v$active_session_history, it keep on changing after every 10-15 minutes. Using below query to find the sql_text for the session from v$active_session_history.
select sql_id, sql_text
from v$sql
where sql_id in (
select sql_id
from v$active_session_history
where session_id=511
[code].....
We have not faced issue like this during Peoplesoft upgrade. what could be the reason that the status is not changing while the base sqls keep on changing after every 10 minutes.
How to find the sid from v$session of my current session.
I want to ask:
Let say I have open 10 TOAD session and only in one toad session i have fired a sql query ( the rest 9 session are just blank), then the rest 9 status are in active status. Now, how i can figure out which sid ( from v$session ) belongs to which session as all the 9 session having nothing to run.
Quote: My main intention is to find out the current session sid as soon as it make connection with DB.
I have a question about spfile.
SQL> SELECT COUNT(*) FROM v$parameter WHERE value IS NOT NULL;
COUNT(*)
----------
246
SQL> SELECT COUNT(*) FROM v$spparameter WHERE value IS NOT NULL;
COUNT(*)
----------
20
v$parameter displays information about the initialization parameters that are currently in effect for the session,but v$spparameter displays information about the contents of the spfile.I want to know why the count of parameters whose values are not null in v$parameter is greater.where are they from? My initialization parameter file is spfile.
How I can find the hostname for an oracle session id?

11.2.0.3 EVENTS: Null(blank) or called a 'null event' See link. Checked the docs. I don't see anythingI think a null (blank) is for an idle wait since per the V$ACTIVE_SESSION_HISTORY spec these are not record. Am I correct?What is a 'null event'. I see a paper from Oracle magician dating to 9i that says this is an 'oracle goof'. Descriptions of Wait Events
