Regarding ORA-01102 ORACLE COULD NOT MOUNT DATABASE IN EXCLUSIVE MODE.

Hellow Friends,
I was testing my recovery strategy for control file. Out of two my control files I deleted one and tried to start when oracle gave me error that could not find so and so file in such and such location. I than copied first member which is in other location to the deleted file location. Since than I could not start my database gving me same error ORA-01102.
Yes I can recreate control file because I am having all my other files intact.
Now is there anybody who share knowledge with me to feel me pride of such honour.
Thanks All.
Your Friend.
Sumeet.

Hi all
On this - it had me vexed for a while, I was installing
8.1.7 on Solaris 2.9 - but when I went to prep the db,
kept on getting the error 01102.
Found out that if I shut down the db (immediate),
changed the 'remote_password' param to shared then went back in to svrmgr - reshut the database and redid startup pfile=$ORACLE_HOME/etc it cured the problem.
Suspect this is a hangover from 7, when Oracle kept enforcing defaults on setting up dbs, bit like their catalog and catproc scripts, they still have errors that were there in the
year dot.
Cheers

出现这个问题，可能是由于断电的问题，解决方法是
出现1102错误可能有以下几种可能：
一、在HA系统中，已经有其他节点启动了实例，将双机共享的资源（如磁盘阵列上的裸设备）占用了；
二、说明 oracle 被异常关闭时，有资源没有被释放，一般有以下几种可能，
1、 oracle 的共享内存段或信号量没有被释放；
2、 oracle 的后台进程（如SMON、PMON、DBWn等）没有被关闭；
3、用于锁内存的文件lk<sid>和sgadef<sid>.dbf文件没有被删除。
首先，虽然我们的系统是HA系统，但是备节点的实例始终处在关闭状态，这点通过在备节点上查数据库状态可以证实。
其次、是因系统掉电引起数据库宕机的，系统在接电后被重启，因此我们排除了第二种可能种的1、2点。最可疑的就是第3点了。
查$ORACLE_HOME/dbs目录：
$ cd $ORACLE_HOME/dbs
$ ls sgadef*
sgadef* not found
$ ls lk*
lkORA92
果然，lk<sid>文件没有被删除。将它删除掉
$ rm lk*
再启动数据库，成功。
如果怀疑是共享内存没有被释放，可以用以下命令查看：
$ipcs -mop

s 45078 0×67e72b58 –ra-r—– oracle oinstall
根据信号量ID，用以下命令清除信号量：
$ipcrm -s 45078
如果是 oracle 进程没有关闭，用以下命令查出存在的 oracle 进程：
$ ps -ef|grep ora
oracle 29976 1 0 Jun 22 ? 0:52 ora_dbw0_ora92
oracle 29978 1 0 Jun 22 ? 0:51 ora_dbw1_ora92
oracle 5128 1 0 Jul 5 ? 0:00 oracleora92 (LOCAL=NO)
然后用kill -9命令杀掉进程
$kill -9 <PID>
总结：
当发生1102错误时，可以按照以下流程检查、排错：
1.如果是HA系统，检查其他节点是否已经启动实例；
2.检查 oracle 进程是否存在，如果存在则杀掉进程；
3.检查信号量是否存在，如果存在，则清除信号量；
4.检查共享内存段是否存在，如果存在，则清除共享内存段；
5.检查锁内存文件lk<sid>和sgadef<sid>.dbf是否存在，如果存在，则删除

No, its still not helping..even after trying to kill the semaphores:

ORA-01102: cannot mount database in EXCLUSIVE mode

Hello,
I am working with an Oracle VM Template: Oracle Application Server 10g Release 3 WebCenter (x86 32-bit). In this template exists an Oracle database (version: 10.2.0.3.0), I am trying to do something operation (ie create a new user, query a system template, etc) but I can't because I have ORA-01102 error.

So, I have checked listener.ora and tnsnames.ora and they are OK, so I don't know why I can't access to the DB.
Any idea/suggestion is welcome!
Thank you in advance and regards,

Problem with Dataguarg ORA-01102: cannot mount database in EXCLUSIVE mode

Hi,
I'm trying to create a physical standby database on my Oracle9i DB runing
on WinXP.
Note: I have both Primary and Standby on the same system.
Actually everything went well .... I did created the standby DB but the problem
is I can not start my primary DB if my standby DB is mounted.
I get this error:
ORA-01102: cannot mount database in EXCLUSIVE mode
And when I read about the error message I learnt that I should start my DB in
compatible mode ... please how do I do that?
Or possibly how can I make this work.
Regards,
Cherish

Actually, I remember doing that in the Pry pfile but cannot really remember if I do that in the standby pfile.
I'll check and get back to you.
I'm very grateful for that.
Regards,
Cherish

PMON and ORA-01102: cannot mount database in EXCLUSIVE mode error

hello all
I have been asked to look into a problem server with the following details
OS: sunOS 5.8
Oracle: 10.2.0.1
sys user password is not available !
backgrround processes for the instance(sid=test) are running
only schema credentials available and with that user is able to connect.
verified all oraenv parameters(ORACLE_SID is same as the running instance(test)).
only one instance is configured in this server(verified all tnsnames.ora, data files etc).oratab is empty
the issues are,
when I tried to connect to the server using "oracle" user using conn / as sysdba
1. Tried to shutdown using , shutdown immediate
ORA-01507:database not mounted
ORACLE instance shut down
still able to see the background processes and user is able to connect
2. Tried startup command,
In the nomount state I can see more than one PMON process with the same sid
when tried to mount/open
ran into the error,
ORA-01102: cannot mount database in EXCLUSIVE mode
Eventhough the background processes for the "test" instance are running I am not able to shutdown the instance using "oracle" user
please help
newbie

hi
i renamed lk* file but the issue still remains,
with the oracle user
1./ as sysdba
2. shutdown immediate
this leads to
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
SVR4 Error: 2: No such file or directory
still not able to identify the running oracle instance.
there is only one oracle home and the oraenv details are set with the correct values
verified the alert log(ora home details are matching with the env details), details of the oracle processes which are active are in the alert log along with the startup failures(mount errors) at the tail end
oracle sysdba is not able to identify the already running instance?
please help

ORA-011-2 cannot mount database in Exclusive mode

This is brand new both Oracle 10g and SUSE 9.3 install. The installation went fine, no errors. At the end I tried to verify the installation:
sqlplus /nolog
SQL>connect / as sysdba
Connected to an idle instance
SQL>startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/opt/oracle/product/10g/dbs/initmydb.ora'
SQL>
So, I figured the missing initmydb file must be in different directory so I looked for it, started new shell session and entered this:
ln -s @ORACLE_BASE/admin/orcl/pfile/initmydb.ora
$ORACLE_HOME/dbs/initmydb.ora
Now I get the following error:
SQL>startup
ORA-011-2 cannot mount database in Exclusive mode
This is third time that I am triyng to install both SUSE and Oracle from scratch and I always run in the same problem, so you can only imagine how I feel.

Now after reading many documents I am even more confused. The thing is, now I can connect to EM and manage database, create tables, etc, which means the database is up, right? However, I am unable to verify the database existance in sqlplus.
First after I connect as sysdba in sqlplus, the console says "Connected to an idle instance". When I enter show sga sqlplus, the sqlplus displays 0. Startup comand will display error in the above post.
So, the bottom line is, according to the EM the database is up and running (I can use isqlplus too) but not according to sqlplus on the server itself. What'sgoing on here? I've been reading every single paper on Oracle's and Novell SUSE web sites and couldn't find anything about it.

Error message in Command line (cannot mount database in EXCLUSIVE mode)

Hello Experts
I'm new in Oracle and trying to connect to my database though SQL command line. After I login as SYS I user I get the message that 'connected to idle instance'. Then I use “STARTUP” to connect to database. Now from my understanding it should mount the database and open it as well. But it does'nt happens.Instead I get the message 'cannot mount database in EXCLUSIVE mode' . I'm not sure why it can't mound the database and what should I do to make it working. Please can somebody show me how to make it working again. Here are the details about my problem
Enter user-name: SYS as SYSDBA
Enter password:
Connected to an idle instance.

Thanks a lot in advance.

Thank you so much for both of you. I've checked everything. All looks fine to me and then i tried to connect though SQL and it worked. Now what I've notice that this time I didn't start Enterprise Manager only I started the listner and then start sql it worked. Does this means that I can't use both SQL and EM at a time together?

Pls need your help!! ORA-01102: cannot mount database in EXCLUSIVE mode

I really appreciate if you can help me.
In the test environment Oracle 10g r2, I was trying to change some init.ora parameters and some flashback database parameters. Flashback required to start in mount exclusive, and the init parameters only start mount. I do not know the difference between mount and mount exclusive. i used start mount exclusive to alter all the parameters. At the end, I used ALTER DATABASE OPEN. Now, I can't start the database. The following is the error that I am getting. Can you explain the difference between start mount and start mount exclusive.
Thanks, Terry

Hi,
According to your description, your problematic database is in dirty shutdown state and your soft repair ends with errors. In this case, I'd like to say, the dirty shutdown state may be caused by that the required log files are missing. Thus, I recommend
you try the hard recovery by using Eseutil /p or
Eseutil /d /r.http://support.microsoft.com/kb/259851/en-us

ORA-12154: TNS:Could not connect to Oracle database.

Hi All,
I'm getting the following error while trying to access OBIEE dashboard.
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 12154, message: ORA-12154: TNS:could not resolve the connect identifier specified at OCI call OCIServerAttach. [nQSError: 17014] Could not connect to Oracle database. (HY000)
I have oracle 10g R2, I can connect my database using SQLPLUS. I am not able to do Update Row Count from Admin tool also. If anyone come across this issue, please share your experience. Anyhelp would be appreciated.
Thanks,
Ravi

The problem is OBIEE server not able to read the tnsnames.ora file. That depends upon the what you set as ORACLE_HOME. that can be find with tnsping command at command line. Follow this article about setting up oracle home and oci drivers
http://oraclebizint.wordpress.com/2007/10/03/oracle-bi-ee-101332-identifying-oracle-homes-for-oci-drivers/
please make sure that your DB-home is the first entry in your PATH environment variable.
Have you created TNS_ADMIN environment variable. Create a environment variable TNS_ADMIN which maps to location where tnsnames.ora file located.
let me know if you are not able to load after this steps.

ORA-12154: TNS:could not resolve the connect identifier specified Oracle 11

I'm having a slight issue with Oracle 11 R2
Oracle 10g was removed from the machine - The registry was cleared and I couldn't see anything of 10g left.
I then installed Oracle 11 with just the software only, and then created a listener.
Using the Database Configuration Assistant, I tried to add a database but I get the error:
'ORA-12154: TNS:could not resolve the connect identifier specified'
The TNS_ADMIN is set to: \\ravel\tnsnames and I can connect to other instances around the company.
My tnsnames entry is:
GMAN_1120.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = gman)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = ora112)
If i start the listener i get:

Can anyone spot what may have gone wrong? I've setup 10g multiple times and never had a problem

I can tnsping my machine using another machine:

08004:[oracle][odbc][ora]ora-12154: TNS: could not resolve the connect ....

This error has just recently started happening, and i cannot figure out why, i have not changed anything in tnsnames.ora file.
i am always able to "test connection" in ODBC. even when i get the error in crystal.
so i restart Crystal, and i am able to connect to db.
strange thing is that always when i do a tnsping to db i always get the message :-
TNS-12541: TNS:no listener
Any ideas ?

I am receiving a similar error.
Failed to open the connection.
Details: 08004:[Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified [Database Vendor Code: 12154]
I've seen all sorts of discussion on the intertubes about possible fixes however, none stated are practical or they do not address my error specifically. I've exhausted resources on the net as well as those available to me.
I'm currently running SAP Crystal Reports 2011 on WIN7 64bit and using Oracle in OraClient 10g_home1.
Please let me know what insight you have. I cannot roll back to previous versions of Windows nor less encryption.
Thank you for your time.

When using a dblink, the database with the link is acting as a client to the remote database ... exactly like sqlplus running on the db server.
