In addtion,output of script below. In particular, I am trying to understand if there anyactive locks.

col sid format 9999

we know we can see lock mode held in session can be analysed using LM column in v$lock.But i confused in seeing LM column it all shows in numbers from 0 to 6.
eg
0,'None(0)',
1,'Null(1)',
2,'Row Share(2)',
3,'Row Exclu(3)',
4,'Share(4)',
5,'Share Row Ex(5)',
6,'Exclusive(6)')
Just noticed MR(media recovery lock ) in our database,further check showd all datafiles had this lock since our database was shutdown abortly but was startup gracefully.

Every day the application cause many locks on database when execute insert, update and delete. I don't understand why so much locks. Are there a way to avoid this? Always I have to eliminate session causing locks.

We are experiencing tx row lock wait time over hours. There is no blocking session and it seems that the application hangs. What is funny is that when we gather_stats on the tables, those tx row lock wait are being released.

We are running a store procedure by calling it from shell script.The shell script is running in Server1 and the stored procedure is running in server2(which is the data base server.).
Functionality of the stored procedure:Generating a tab delimited file and place in a directory.
Requirement: The requirement is that the store should be modified in such a way that it should drop the output file to Server1 itself(The server from where it is getting called).
Attaching the store procedure for reference. mIn the store procedure,we have a variable "lv_file_dir" which currently refers to the directory location in Databse server(Server 2) We have to change this SP such that it drops the generated file in Server1 itself(From where the shell script is running).

I have a server configured to German & English. when i connect with SQLPLUS, i have German language server output, but when i do "alter session set nls_language='AMERICAN'" - it solves the issue for me.
I need the same for expdp command, but I don't know how to do this. I have tried to add a parameter nls_language, but expdp doesn't recognize it. Is it possible to somehow see server output of the expdp & writing it to the log file in English?
is it possible to put DESTYPE=LOCALFILE in run_report_object_list?

So whats can cause this, I can see that TX locks are mostly from JDBC connection from Application server .
In my current project, I am handling an Oracle database with version 10.2.0.3. I analyzed the AWR report for the past month abd saw the following wait events consistently:
CPU time - 45.6% (% Total Call Time)
db file sequential read - 30.6% (% Total Call Time)
enq: TX - row lock contention - 18.8 % (% Total Call Time)
I have uploaded the report for your reference.What should be my approach to troubleshoot this?

how one can lock a particular row in a table.for example i have a employee table in which 50 records. now i want to lock only 10 records of the employee table.
View 8 Replies View RelatedI have a transaction table with some custom properties and two status columns. There are 2 different applications(.Net and Pl/SQL Procedure) using the table. Both the process run parallel and fetch records one by one, perform some calculation and update the status column.
-.Net updates - Extraction_status
-Pl/SQL updates - Ingestion_status
There are likely more chances that both applications will fetch the sane record and try to update the same row. This will cause a lock. Can i use row level lock before update by each application? Or is there any other methods/process in which this can be handled. ?
begin
for i in 1..10000 loop
update table1
set col1= col1+1
where type =1;
commit;
end loop;
end;
My question is, if a strored procedure contains the script above and the said procedure will be invoked by two or more sessions at the same time. Does it mean that the 1st session will lock the related rows and other sessions will have to wait for loop in session one to finish?

Also , is it like if i have executed a package that is referencing some other package then we wont be able to compile the referenced package until and unless the dependent package has completed its execution ??

In the past, we setup a standby database on our production server. My OS is HPUX, Oracle 10g and my database is in archive mod. We are no longer using the standby database method. My problem now is that one of my tablespace (/oradata/tn/rd2_temp 20gb) became 100% full on my production system. In trying to provide more space, I removed one of the standby redo logs. Instead of using ALTER database, I just did a rm from the OS. As I said earlier my STANDBY DB is inoperatable.
When I tried to drop the tablespace(/oradata/tn/rd2_temp it is 20gb), I am getting an oracle error (ora-19528 redo logs being cleared may need access to files). Im also getting and INSTANCE LOCK on ARC4. The rd2_temp tablespace is now offline. If I get rid of rd2_temp, I will be able to gain more space back to /oradata/tn.
My database is still up and working okay.
