Wait_time vs seconds_in_wait vs last_Call_et in V$session
Hi,
DB : 11.2.0.1
Os : Aix 6.1
we executed the below query once got a call from client due to slowness .
select sid,status,last_Call_et,event,wait_Class,wait_time,seconds_in_wait from v$session where sid=7521;
SID USERNAME OSUSER PROGRAM WAIT_TIME SECONDS_IN_WAIT SQL_ID
7521 DRGR MAGR01 JDBC Thin Client -1 22926 g5mwxjn7jsfp6
After some time,executed again
select last_Call_Et,WAIT_TIME,SECONDS_IN_WAIT,status,event from v$session where sid=7521;
LAST_CALL_ET WAIT_TIME SECONDS_IN_WAIT STATUS
EVENT
*30413 -1 25347* ACTIVE
latch: cache buffers chains
I checked in oracle documentation regarding wait_time and seconds_in_wait (http://docs.oracle.com/cd/B19306_01/server.102/b14237/dynviews_2088.htm)
If wait_time=* -1 *,what SECONDS_IN_WAIT represents?
what is the difference between wait_time vs seconds_in_wait vs last_Call_et in V$session.
Thanks & Regards,
VN

SECONDS_IN_WAIT column of v$session in 10gr2!!
Hi, all.
Recently, I have found the unbelievale value for SECONDS_IN_WAIT in v$session view. The database is 10.2.0.2.0.
select sid, wait_time, seconds_in_waits,wait_class, event,state from v$session;
SID WAIT_TIME SECONDS_IN_WAITS WAIT_CLASS EVENT
500 0 117874 Cluster gc buffer busy WAITING
In the above example, session 500 is waiting for something for 117874 seconds.
117874 seconds is 32.7 hours(117874/60/60).
Thus, session 500 is waiting for 32.7 hours.
The unit of SECONDS_IN_WAITS column is really "seconds"????

Thanks and Regards.Hi, yes the metric is on seconds, you must review the definition for this field on the view, look this.
<br>
<br>
If WAIT_TIME = 0, then SECONDS_IN_WAIT is the seconds spent in the current wait condition.
<br>
<b>
If WAIT_TIME > 0, then SECONDS_IN_WAIT is the seconds since the start of the last wait, and SECONDS_IN_WAIT - WAIT_TIME / 100 is the active seconds since the last wait ended.
</b>

Monitoring Oracle session with SQL_ID
Hi All,
How can I know a SQL_ID belonging to a user/schema in Oracle. Can anyone post me the query to find the SQL QUERY/SQL_ID belonging to a user session. I have googled but dint get what i expected. Hope I get it here. We dont have OEM configured to monitor the session.

Object locked in v$locked_object but can't find session/process blocking
Hi,
I am on database 10.2.0.5, windows x64.
A developer calls me and tells me there are locks on 3 tables, and the locks are not released.
So I run this to see which objects are locked by which session
select vlo.object_id, vlo.session_id, vlo.oracle_username, vlo.process
, DECODE(vlo.LOCKED_MODE, 0,'NONE', 1,'NULL', 2,'ROW SHARE', 3,'ROW EXCLUSIVE', 4,'SHARE', 5,'SHARE ROW EXCLUSIVE', 6,'EXCLUSIVE', NULL) LOCK_MODE
, do.owner, do.object_name, do.object_type
, vs.saddr, vs.serial#, vs.paddr, vs.username, vs.ownerid, vs.status, vs.server, vs.schemaname, vs.osuser, vs.machine, vs.program, vs.type, vs.logon_time, vs.last_call_et
, vs.blocking_session_status, vs.event#, vs.event, vs.wait_class#, vs.wait_class, vs.wait_time, vs.seconds_in_wait, vs.state
from v$locked_object vlo
inner join dba_objects do on (vlo.object_id = do.object_id)
left outer join v$session vs on (vlo.session_id = vs.sid)-----------
I get (after finding out my table locks come from SID 514)
OBJECT_ID SESSION_ID ORACLE_USERNAME PROCESS LOCK_MODE OWNER OBJECT_NAME OBJECT_TYPE SADDR SERIAL# PADDR USERNAME OWNERID STATUS SERVER SCHEMANAME OSUSER MACHINE PROGRAM TYPE LOGON_TIME LAST_CALL_ET BLOCKING_SESSION_STATUS EVENT# EVENT WAIT_CLASS# WAIT_CLASS WAIT_TIME SECONDS_IN_WAIT STATE

I run it again and I get something different, this time the lock is still there, but no session. select * from v$session where sid= 514 returns nothing.
I get
OBJECT_ID SESSION_ID ORACLE_USERNAME PROCESS LOCK_MODE OWNER OBJECT_NAME OBJECT_TYPE SADDR SERIAL# PADDR USERNAME OWNERID STATUS SERVER SCHEMANAME OSUSER MACHINE PROGRAM TYPE LOGON_TIME LAST_CALL_ET BLOCKING_SESSION_STATUS EVENT# EVENT WAIT_CLASS# WAIT_CLASS WAIT_TIME SECONDS_IN_WAIT STATE

373025 514 ROW EXCLUSIVE IRMFIN IC_BIN_DETAIL_STATUS TABLE
373055 514 ROW EXCLUSIVE IRMFIN IC_LOT_STATUS TABLE When I run the query later, I sometimes get another session, but the lock stays. It seems here, that I am catching the same SID on new sessions, but it is probably a different serial # than the original session locking the table rows.
I get nothing from
select * from dba_waiters;
select * from dba_blockers;
Now why are those 3 tables row locked on some rows and I can't find the session responsible? The developer tells me his application crashed and the rows are locked since.
So far ( keep in mind I am not a locking expert) the only way I found to release the locks is a DB bounce, its a test DB so no biggy.
Is this a bug? Am I missing something?
This is the second time this has happened. How can I solve this issue?
Best wishes to all.Thank you for your reply.
I do not think I can kill the session (514) it does not exist, even though v$locked_object reports tables are locked by session 514

How can a session have an ACTIVE status with a WAITING state
Hi all,
I would like to know the difference between status and state of a session ?
The documentation says :
for status ACTIVE : Session currently executing SQL
for state WAITING : The session is currently waiting...
How can a session execute a SQL statement and be waiting at the same time ?
Regards,
fcjunic.Hi fcjunic,
It's really not paradoxical, once you understand the definition of the terms.
First, we have V$SESSION.STATUS, which can be ACTIVE or INACTIVE. A session is ACTIVE if it's in a database call. So, think of this from the client side point of view. A session does a parse call, or an execute call, or a fetch call, etc. For the duration of that call, till control returns back to the client, that session is said to be ACTIVE.
From the time the calls returns, till the time of the next call, the session is INACTIVE.
Next, we have V$SESSION.STATE. This is probably more useful to think of from the server process point of view. This refers to whether the server process is currently running, i.e. on the CPU, or WAITING, i.e., waiting on a resource. Possible values for this column are WAITING, WAITED KNOWN TIME, WAITED SHORT TIME, and WAITED UNKNOWN TIME. Of those possibilities, a session is only actually waiting if STATE is WAITING. All the other values mean that it's no longer waiting, but is running on CPU.
A session w/ STATUS of INACTIVE, will always be in STATE of WAITING, waiting on the 'SQL*NET message from client' wait. So, in that case, it means the server process is waiting around for work to do. It's in between calls, so, STATUS is INACTIVE, and it's waiting on that network port, to receive the next call from the client.
An example of a session that's ACTIVE and has STATE of WAITING, would be a session that's, for example, doing a full table scan. So, it's got lots of data to read from disk. While the session waits for the read from disk to complete, the session waits on 'db file scattered read'.
Finally, for completeness, the difference between the different possible values of the STATE column. I already covered WAITING. If a session is not waiting, it's now on CPU, and it previously waited. If so, it either waited more than 10 ms, in which case it will report WAITED KNOWN TIME, or less than 10 ms, in which case it reports WAITED SHORT TIME, or timed_statistics is false, in which case this column will always be WAITED UNKNOWN TIME. Also, it's important to pay attention to this column, when trying to interpret the WAIT_TIME and SECONDS_IN_WAIT columns.

on what basis, session is shown as inactive in the status column of v$session..
am connected through toad and execute so many queries, but still my session is shows as inactive ..
can anyone shed some lite on this ?
KaiMark,

This is the output that I got from V$session which has got one user ,Aman connected and ran a long query which took sufficiently good amount of time to get complete.

I am getting 23 rows and than 24 ,the second last one becomes an active session but my session,Aman's,remains inactive only. The last_call_et column is also shown which according to docs,is showing time period of staying inactive. Interstingly, I couldn't make my user's status changed to Active. My best guess is that it might have become active when the call was submitted but after that it has become inactive again.I surely can be wrong but just wanted to share my thought.If you can explain the behaviour in more detail,it will be great.

Query completed but session still not released.
Hi Everybody,
We are trying to refresh a materialized view using a below mentioned command,
exec dbms_snapshot.refresh('NESTER.MVREPAIR','?');
While querying v$session_longops we are getting the work complete output.
1* select sofar,totalwork, time_remaining from v$session_longops where sid='245'
SQL> /
SOFAR TOTALWORK TIME_REMAINING
32018 32018 0
However the session from where we are trying to referesh the materialized view is still not released.
It seems oracle is still doing something in the background.
Also after querying LAST_CALL_ET from v$session, the value keeps on changing.
select LAST_CALL_ET from v$session where sid =245;
LAST_CALL_ET
1099
SQL> /
LAST_CALL_ET
1102
Please suggest..!!Am I missing something here?
LAST_CALL_ET is a number indicating the time since the last query from the session was fired. It would go on increasing till the session is connected and remains idle.
If you have not done anything from that session after the refresh, the LAST_CALL_ET is going to go on. Ever increasing.

How to identify a user, suppose a user is opening a AR transaction form and its taking enough time, like more than an hour; how could i identify that particular user ? please suggest any scripts or any related ways.
Thanks n appreciate.I think LAST_CALL_ET of v$session will help to identified this kind of user.
What LAST_CALL_ET represent in v$session
As per oracle doc
If the session STATUS is currently ACTIVE, then the value represents the elapsed time in seconds since the session has become active.
If the session STATUS is currently INACTIVE, then the value represents the elapsed time in seconds since the session has become inactive.

Last_call_et keeps resetting, no other evidence of activity
I'm trying to debug an issue with a process that pulls a bunch of data into an Access database from a couple of Oracle databases (yes, we're working on killing Access). Almost everything I can see is telling me that Oracle is doing nothing and it's purely an Access issue but last_call_et in v$session keeps resetting itself which makes me believe that Oracle is doing something. I'd be really appreciative if anyone can help me figure out what I'm missing.
What I'm Seeing
When I query gv$session, I'm seeing the session that Access opened. Every time I look, the status is INACTIVE, sql_id is NULL, and prev_sql_id is a constant value. When I look at gv$sql for that prev_sql_id, executions isn't increasing and executions = end_of_fetch_count. So far, so good, Oracle's off the hook.
However, when I pull in LAST_CALL_ET from gv$session, that value never gets above 10 seconds. It's constantly resetting. That makes me believe that Oracle is doing something every few seconds. But I can't for the life of me think of anything that it could possibly be doing that wouldn't cause a change in prev_sql_id or a change in the number of executions of the SQL statement.
Is there something that I'm overlooking here?
Thanks!

SQL*Net message from client
It does appear that the Access changes resolved the overall issue. But while Access was chugging away, I was still seeing LAST_CALL_ET getting reset with no other obvious signs of activity.
Justin
If it was changing between FROM and TO there must have been some message coming from Access and bouncing back without an error. Possibly some sort of OCI "ping" type call that didn't involve an SQL statement.
Update: something like a "set context" or "set client identifier" perhaps; possibly a (non-SQL) rollback or commit

Let´s say i have a session that connects to the database without the listener (beq or ipc)
this session has a infinite loop like
begin
loop;
insert into ....
commit;
end loop;
end;
i kill this sql*plus session with the "X" Button, so the transaction still continue.
How can i find this "dead" session?
Any Ideas ?
Thanks in advance
Marco
PS: sqlnet.expire_time only works if you connect through the listenerthanks for the fast reply and ok it´s a theroretical question
but if i have 100 Session with the same username i can´t find it this way.
i tried it with last_call_et in V$session but it dosn´t work also.
Mayby comparing the process id of v$process with the process explorer (sysinternals)
but isn´t there a easy way to find dead sessions ?
Thanks

Sessions going on Increasing in the DB
Hi All,
In our environment we are using weblogic on which CRM Application is deployed.
Initial Capacity -- > 1
Maximum Capacity -- > 25
However the sessions in database when we query the below are huge in nos :
select * from gv$session
As the sessions at the database end , we are not able to connect to the DB until we manually kill the session
Could anybody throw some light whether there is any eficient way to handle DB sessions from Weblogic end thru some parameter or Some best practices which could be followed ??
Thanks in AdvanceHi,
I m Just Throwing some light,with below few sql queries..this usually helps in my environment..Consult with DB Guy before executing the query in production.
1)Below Query will show session information and time of execution

to_char(a.logon_time,'DD-MM HH24:MI:SS') LogonDate, a.osuser, a.status, a.module,a.last_call_et
from v$session a, v$process b where a.paddr = b.addr
and a.status = 'ACTIVE' and a.username is not null
order by 8 desc
2)Below Query will show all active session

PL/SQL procedure successfully completed.It's incomplete for the types being recognized.
And the reason for need to deal with the types in the first place is:
Some tables use hyphen in columns names (e.g. v$transaction: DSCN-B, DSCN-W).
That's why i need translation from '-' to '_' to be able to print.
Otherwise '-' is recognized as minus operator (is there another way around w/o dealing with the types?).
Another question:
Is it possible to extend this to work with result of some cursor
- e.g. returning result of joining #2 tables?
best regards,
Frank

Capture stuck at one archive file
I have set up a 1-to-1 one-way streams replication in Oracle 10.2. (schema level capture).
Source DB (SRC)& destination DB (DEST) on : SUSE Linux Enterprise Server 10 SP2 (ia64)
The capture, propagation and apply did run okay for few hours. Now I find that the capture is stuck at a particular archive file and not moving further. I also registered the archives manually using:
alter database register or replace logical logfile ....
This also has not helped.
Please help. Thanks.We suppose that you have already tried to stop/start the capture.
Creating LCR is an Internal Streams action which cannot be impeded by any form of data locking. So you are facing a database resource constraints (library cache lock on a streams structure) or an archive log corruption, usually after a file system full with 2 destination registered and you retook the archive which was on the file system full(I already met this once).
Run this to check you don't have any library cache lock:

Query running slow in one node
Hi All,
We are running 4-node Oracle 10g RAC (linux 64-bit). The query is running fast in one node, but the same query is running very slow in the other node. And sometimes, we see pin S wait on X wait event in top 5 events.
Has anyone faced this kind of situation before ?
