ENQUEUE_LOCKS

Oracle Version 9i and 10g
OS All versions of Linux
I observer in some databases that ENQUEUE_LOCKS resource (which we get when we query V$Resource_limit ) reaches the maximum level for quite some time. I just want to know
(1) What is the reason for this ?
(2) Is it serious enough to affect the database availability and performance ?
(3) Some DBAs here try to increase this parameter and then bounce database for this to take effect. Is it the right way to deal with this situation ? Are there any other way to deal with this issue ? Since these are production databases arranging for bouncing of database frequently is problematic.
(4) I tried to find information about this resource. But couldn't get much info. Are there any source of information which clarifies this issue on Web ?

As SB has asked already, the parameter enqueue_lock is not a public parameter but from a long time back, its an undocumented parameter leading to mean that it should not be tempered just like that. Changing it without the consent of OSS can lead your database be marked as unsupported.
I am giving a link of Oracle Wait Interface book which explains it in a quite good manner. Read it and than only decide that whether you do need to play with the parameter or not.

That's a fairly dramatic change from the last output - a huge volume of direct path reads - 652,742 reads could mean as much as 652GB - which is reflected in the 95,000 blocks per second. Your hardware can deliver a lot of reads when it tries ... but your job is to find out why. It's possible that 11.1 has simply changed some execution paths on you - or it might have decided to do some serial direct read table scans.
You said increasing logfile size to 2 GB. That would be a drastic increase ! May i ask you how did u derive that 2 GB ? Log switches are pretty high for about 2 hrs only when LOAD is executed, After that its pretty stable. We have FSFO configuration on my physical standby as well. Would there be any effect on by log-shipping activities on standby having 2 GB log file size ?
Your redo rate suggested you were switching every 15 seconds. Log file switches lead to large numbers of CF enqueue requests; I just suggested a size that would lead to switches every 4 minutes. I don't know all the subtle details of fast start failover - the log files and standby log files have to be matched, of course; but I don't think the absolute size of the log files is a consideration since you'll be pumping the redo to the remote site in real time, not at a log file switch. How frequently do the log files switch when you are not loading ? If you increase the log file size you can always set the archive_lag_target parameter to that many seconds.
All 'db file sequential reads' are on PK (all Index Unique Scans on Local PK) as all merges are based on my pk. Presumably the merges update the tables, and so there are random accesses to tables and to other indexes, though.
High #of executions are also due to concurrent merges and could of merges (small volume) are having Nested-loop in PK.Are you using the merge command with a high volume on each call, or have you done something like creating a loop that does a uses the merge with one row of data at a time, or does "merge" mean something other than the merge command ? The merge command exists as an efficient mechanism for merging a large volume of data into a VERY large volume of data with a single SQL operation.
I have 16 cores and 64 GB RAM.
May i ask you how Oracle derives '_enqueue_locks' parameter value ? I have transactions=150,sessions=500,processes=450 and dml_locks=60. Can you advice me whether i should increase this hidden parameter or what ? If yes, would there by any sub sequences ?
I don't know how enqueuelocks is derived. It used to be something like: 10 * sessions + 2 * processes + db_files + a couple of other things
Why do you have transactions set lower than processes, and how come your dml_locks parameter is so low. Transactions defaults to something like sessions + 10%, and dml_locks defaults to something like 5 * processes -- those are both ballpark figures, I can't remember exactly what the rules are.
I showed you in a previous post how to check if anything needed changing. Query v$resource_limit and check the max_allocation with the limit. It's not often that anyone uses anything like the limit set for enqueue_locks, but possibly you mess
Your comment on commit rate is also interesting (user commits/sec is just 1.41) . Yes, our merges are row-by-row processing and i am sure job is putting COMMIT once entire merge is executed. Is that an optimal load design ?I think this answer the question further up the page - is your "merge" a real merge command or a "update, if no rows updated then insert pl/sql".
Since 'log file sync' is not a problematic area, i think LGWR is neither starving for CPU nor for Memory. I am sure my IO is also good.I wasn't worried about your commit rate - I was curious that you did a small number of commits with a very large number of executions. There are no indications in stats you've shown me to suggest that the log writer has, or is, a problem. However you are doing too much I/O and need to reduce it if you want to make your processes go faster.

Error while running commands at RMAN prompt

Hi ,
We have a few oracle 10g(10.2.0.3) databases on AIX platform.We use RMAN backup with a recovery catalog database.
The rman full(level 0)backups are scheduled dailly and running fine.When I tried to run commands like 'list backup','report obsolete' I'm getting the following errors.

But the recovery catalog database is up and running fine.For few other databases I'm able to run the above commands without errors and for some databases I'm getting the errors as mentioned above.
Could someone help me out with this...

Thanks Tycho for your reply.

I am getting below error while taking RMAN backup.

Friends,
I am getting below error while taking RMAN backup.
The issue is related with a lock while trying to backup the controlfile.
The lock is more likely caused by the autobackup controlfile process started just before RMAN process was also trying the backup controlfile as shown in the following alert.log excerpt.

Smartform Activation[program "SAPLSUNI" has exceeded the permitted runtime]

I was working on a smartform. For 2-3 Hrs it was working fine, whatever changes I was making were getting activated smoothly.
Then, for some unknown reason the smatform stopped getting activated. Timeout dump is happening. But when we 'Check' the smatform, no error is coming. Still it is not getting activated.
I checked another smarform & made some changes, activated....it got activated instantaneously. The function module of that smartform that it is showing in Environment -> Function Module Name -> /1BCDWB/SF00000144
But when we check SE37, it says no such module exists !!! Please help !!!!!!!!!!!!!!!!!!!!!!!
Here is the dump :
Runtime Errors         TIME_OUT
Date and Time          01.06.2010 12:37:24
Short text
     Time limit exceeded.
What happened?
     The program "SAPLSUNI" has exceeded the maximum permitted runtime without
     interruption and has therefore been terminated.
Error analysis
     After a specific time, the program is terminated to make the work area
     available to other users who may be waiting.
     This is to prevent a work area being blocked unnecessarily long by, for
     example:
     - Endless loops (DO, WHILE, ...),
     - Database accesses with a large result set
     - Database accesses without a suitable index (full table scan)
     The maximum runtime of a program is limited by the system profile
     parameter "rdisp/max_wprun_time". The current setting is 600 seconds. If this
      time limit is
     exceeded, the system attempts to cancel any running SQL statement or
     signals the ABAP processor to stop the running program. Then the system
     waits another 60 seconds maximum. If the program is then still active,
     the work process is restarted.

Hey Guys,
For some reason, the problem automatically got resolved. First I check STXFADMI table to find entry of the FM against that smartform. When I punched the FM name of the smartform in SE37, it repeatedly said "FM does not exist". But the entry for that FM is present in the STXFADMI table. Hence I started debugging SE37 after entering the FM name. To my surprise, at the end the FM was displayed !!! After that I went to the smartform & activated, again surprised....it got activated in a flash !!!
Can anyway justify this mystery ?

How to delete mulitple ABAP Programs?

Hi,
I want to delete multiple programs in the SAP Production server using a Transport Request(TR).
Can someone suggest a FM(Function Module) or code by which i can delete multiple programs in development system and all the deleted programs come under the same Transport Request?
This will help me in deleting the same in Production system as well.
Basically i would say if u delete programs using SE38, the system prompts u for a TR.If u give the same TR for all programs, then all of them(deleted programs) would come under the same
TR.
This is wht i want to replicate. I cannot manually delete the programs as the no. of programs is close to 300.

you can use function module 'RS_DELETE_PROGRAM' to delete reports.
to delete multiple reports, collect the report names to be deleted into an itab and loop at itab and call this function.
call function 'RS_DELETE_PROGRAM'
               exporting
                    program            = l_s_pdir-progname

Clearing Lock Reason

Dear Experts,
I have set the Clearing Lock in the document. I have searched in the DFKKOP table, where I am not able to identify the document number with clearing lock reason.
I am having requirement that, if the line item is overdue system should lock the partcular line item, Is there any way to set the payment lock automatically?
Could anyone please guide me in which table I can identify the document number with clearing lock.
Thanks in Advance,
Aswin

Oracle Process

Dear Gurus
We are working in Online Application, and certain peak time our database activity increases and more than 1100 users login. ( checked in view v$session and v$parameter )
Process parameter value = 1100
sessions paramter value = 1215
OS : Windows 2003 server
Oracle : 10.2.0
RAM : 20 GB
SGA_TARGET : 7GB
Server : Intel Xeon (R) 8 cpu
Issues : DB server usage went 100% for few seconds, and then back to around 50%. Some users get DB server errors, because the process parameter is limited to 1100.
Can you guide me ? should I increase the process parameter to 2000 ??
or should I replace the existing server with heavy server and then increase the process parameter to 2000.
Kind Regards.

You can check v$resource_limit

You can think of increasing the values of the parameters

How to know which session id has acquired an object ?

Hello,
We work on database 11.2.0.2 and aw 10G style.
concurrent users attach an aw in multi mode.
They make update on cubes and on dimensions.
They use the olap command Acquire before update changes.
When an object cannot be acquired, i would like to know which session lock this object.
best regards
jean marc

That's an interesting question. I'm surprised that nobody has asked it before. The following query will identify all sessions holding object locks:
select a.aw_name,o.obj_name objname, e.sid sess_id
from dba_aw_obj o, gv_$enqueue_lock e, dba_aws a
where
e.type='AO' and
o.aw_number=e.id1 and
a.aw_number = e.id1 and
bitand(o.obj_id, 1073741823) = e.id2;

DEAD LOCK ERROR

When we are using our oracle application, our session hang every time the user update records. the DBA said that we have a dead lock error... the only thing he did is to reset sa database every time we in counter this problem. but we have this error every day, and i don't have an ideal regarding what is dead lock.

you don't have a deadlock problem, because a deadlock will be "solved" as oracle simply kills the blocking session and rollbacks the changes.He is right. you might have blocking problem not dead lock problem. Find out the blocker and waiter and kill the blocker session.
Following query would give you an idea about who is blocking and who is waiting for :
select /*+ ordered */
a.sid blocker_sid,
-- c.sql_text,
a.username blocker_username,
a.serial#,
-- a.logon_time,
b.type,
b.lmode mode_held,
b.ctime time_held,
c.sid waiter_sid,
c.request request_mode,
c.ctime time_waited
from v$lock b, v$enqueue_lock c, v$session a, v$sqltext c
where c.address=a.prev_sql_addr and
a.sid = b.sid
and b.id1 = c.id1(+)
and b.id2 = c.id2(+)
and c.type(+) = 'TX'
and b.type = 'TX'
and b.block = 1
order by time_held, time_waited
Look for blocker_id and waiter_id. If possible, kill blocker using following command.
select sid,serial# from v$session where sid = blocker_sid;
alter system kill session 'sid,serial#'';

Thanks for comming back.
while this issue happens login to db directly even as sysdba takes a while and could not even view listener status. I tried to kill some of the processes base on below cmd.
ps -eaf|grep LOCAL
then I am able to connect to db , also Listener responds.
i also noticed queuesize was set on listener.ora and removed it , and set the trace levels to 10.
Listener has been restarted now. Seems stable at the min.
But i am not sure if the actuall issue has been resolved or not.
I also checked the resource limit
none of them reached limitation
