I have setup of two node (prod-db1, prod-db2) clustered database 11gR2 on windows 2008 R2 server. Everything is working fine at this setup.
My question is: Is there a way to make the Enterprise manager Database control run and be available at both the nodes independently. What I see that even at node 2 (which is prod-db2) the EM-DBControl is (https://prod-db1:1158/em) - which means the agent is running at node 1 (prod-db1) only.
My question is that how to make the EM-DBControl also run separately at prod-db2. My idea is to make the high availability of EM-DBControl (in case Prod-db1 machine is down).
I have a RAC 48 cores on solaris. I check dbconsole when application performance is very slow and everyone complains, and I see that the main wait is cpu - also on the awr report. however when I check server cpu I see about 80% idle! so how can I make oracle use more cpu power instead of waiting for it? I don't think that parallel is an option here because I can't change the application code.
I am running oracle linux 5.7 on VMware Workstation 9 and trying to install Grid 11gr2, during installation my system freezes and I see out of memory errors. Actually Java installer is eating up too much memory over 1gb. Is there a way ? I can limit memory usage by Java process to a certain extent ?
develop a Oracle stored function or procedure to confirm a availability of datafile on a specific local directory to be read by Oracle External table. The fine looks like filenameddmmyyyy.csv.
I have create a Oracle directory named data_dir that is mapped with physical directory c: mep
Once it is confirmed that datafile is available the ETL process is started.
1)On primary Database Standby Redo log is required for switchover and on standby database Standby Redo log is required for
--Real time Apply --Maximum protection or Maximum availability
Am I correct?
2)My database is in Maximum Performance mode. I set up following entry on init.ora: LOG_ARCHIVE_DEST_2='service=standby LGWR ASYNC'. My question is do I need to have STANDBY Redo log file on standby database in order to use LGWR transport (LGWR ASYNC)mode from primary? Without Standby redo log on standby database can it transport redo data from primary to standby using LGWR transport mode (LGWR ASYNC)?
3)I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode. I would like to know whether is there any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?
How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.
The documentation for v$database says: QUOTE V$DATABASE displays information about the database from the control file. Is it safe to assume that there will only ever be one row queried from this view?
i want to control our session in database oracle10g which means that:x is not allowed to connect to the database, if x try to connect to the database his session will be blocked and a message must be sent to the administrator.
Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0 Agent is running, dbconsole too. to the database through SQL Developer and SQL Plus connects. when you go to localhost:1158/em opens a BLANK PAGE that contains 2 "squiggles" view"|[ ]]" tried in different browsers, identical. a feeling that most web interface is physically not in folders.
I have installed OUI( Oracle universal insaller) and the with DBCA(Database Configuration Assistant) i have installed the database. Before DBCA completion of Database it give error message like database control not running. When i press OK the DBCA completed and database installed but where it shows the database control url it shows database url is null. when i try to give this url http://sweetdba:1158/em it shows error. why the url is not working. 11g database is working and connected.
I installed Oracle database 11g enterprise edition. I can connect it through sql plus but Database control is not starting. I have checked dbconsole service which is running.
the address is [URL]...
but mozilla and chrome both are unable to start the application. after installation it started only once. but it is not starting now.
second thing is how can i confirm what is the port of my listener is it 1158 or something else.
I have multiple oracle (10gR2) databases running on a linux (5.8) server. How can I check that for which of the databases has the OEM Database Control been configured and on what port is it listening?
I m using UTL_SMTP to send mail using my mail server. could i check the availability of 1st mail server, if not available then could i set alternate mail server.
I'm using apex 4.1.1.00.23.I'm wondering whether it is is possible to 'freeze' a production APEX application in a runtime-only installation, during an upgrade. I want to prevent strange behaviour for logged in end users. In the application builder one can set the availability of the application. I was thinking of making the application unavailable during the upgrade. Is this possible in a runtime only env? How? Or are there (better) alternatives?
I was carrying out an experiment in order to crash the database and recover it.
The database was running, I moved the control file to another location and to my surprise the database was still running. I tried issuing checkpoint and transaction but it didn't affect database operations. I tried doing log switch. It completed successfully. According to my understanding and Oracle Certification books database was supposed to crash. But it didn't.
I tried this not only on RHEL, Windows XP but also in Solaris 5.10. The database version is Oracle 10.2.0.4 Standard Edition.
I'm having a problem with performing backups from EM DB Control on two of my Oracle 10g 10.2.0.4 systems. When I configure and submit any backup job from EM (either online or offline), the following happens:
- When the job is due to run a Pre backup task has status of 'Scheduled'
- Prebackup task completes and status changes to 'Succeeded'
- Backup task appears with status of 'Scheduled' and value of started time within the next minute
- Status of backup task never changes from 'Scheduled', and the started time keeps updating to the current time
- This goes on indefinitely until I abort the job
At the moment I have scheduled tasks configured to run an RMAN job every night, but I need to get this working through Enterprise Manager Database control.
Something else which has happended on one of these systems is that after applying some Microsoft Critical updates the database control service would not start. The only way I could find to resolve this was to recreate the Enterprise Manager repository. Could there be a link here at all?
I've also posted this here: [URL] but with no response so far.
I have a problem when I install oracle 11g: I did an installation on a win2008 r2 server and everything works fine, I did another installation on another server in the same network as a test, but at the end of the installation I get an alert that says:
start database error control ..... Executing set oracle_unqname and then emctl start dbcontrol. of course nothing happens.
dbcontrol_nome the service instance will not start. checking the file in your home directory I always acts everything is in place. I reinstalled windows to eliminate all the checks made, repeated installation and here appeared the same problem.
question: can exist 2 oracle installations on the same network with the same name db? I currently have two installations of the same name with oracle db 10
I am getting an error regarding Starting Database Control. I have multiple databases on the same server but every time I am trying to create a new database I am getting the same error again and again.
Installed Grid Control 10.2.0.2.0 on Windows Server 2003R2 32-bit. Immediately upgraded to 10.2.0.5.0. Both install and upgrade went fine, Grid Control can see its own database in the list of targets, looks good.
I then installed Oracle 11gR2 11.2.0.1.0 64-bit on Windows Server 2008R2 64-bit and created a new database. I then installed the 10.2.0.5.0 agent manually on the server via OUI. Agent install went fine, secured and started properly.
The problems I'm having is Grid Control can't seem to see the database instance. If I go to "Targets", GC can see the host just fine, shows that its up and can see targets for the listener (Up), the agent at port 3872 (Up), and the database instance (Down). Drilling down to the database instance, it shows that the instance is not up (though it is as I can connect to it from a different machine and run queries against not) and the Agent Connection to Instance is down with the error: Failed to connect to database instance: (UNKNOWN OCI STATUS 1804) OCIInitialize. Check ORACLE_HOME and NLS settings etc...
Also, pulling up the "Alerts" tab for errors showed the following for Metrics "Access to Important Tables and Views", "DB Data Files Permissions", and "DB Control Files Permission":
Target: SR3 Type: Database Instance Metric: Access To Important Tables And Views Collection Timestamp: Jun 11, 2010 11:11:26 AM Error Type: Collection Failure Message: 1804 at c:oracleagent10g/sysman/admin/scripts/db/esaDbUtils.pl line 290. There are also several "Missing Properties : [AdrHome,ConvertFromCharset,needCharsetConvert]" errors listed too.
I've looked into the 1804 error and from what I could find, its a perl-related issue with not being able to get the ORACLE_HOME information.
- I verified that ORACLE_HOME was set in the environment variables and even rebooted to make sure it was being picked up properly. That didn't work. - I added "$ENV{ORACLE_HOME}='c:\oracle\product\11.2.0\dbhome';" to the esaDbUtils.pl file. That didn't work either. - I added the GC security certificate to the trusted certificates on the target box in case it was some kind of SSL issue. I don't get the annoying "invalid certificate" warning, but it didn't fix it.
I'm trying to create a database using DBCA, but before it completes i recieve the following error:
enterprise manager configuration failed due to the following error - Error starting database control refer to the log file at

I'm using oracle 10g version 10.2.0.5, and my operating system is windows 7
I am using oracle 11g on OEL 5.8. Facing problem in database control, when i browse using database control it shows me missing plugin. I have install jre 6 but no luck.
I have restored database with the name DB to another database called DB01
it is in STARTED status (not mounted) and it seems I can not change the name if it is not mounts, and I can not mount it because of the name, how to solve this issue if possible? I have RMAN full backup from DB on my current server which hosting the database DB01 the initdb01.ora is ready and configured with DB01
what can I do next
ORA-01103: database name 'DB' in control file is not 'DB01'
I'm monitoring and all my databases using grid control. Recently I added a dataguard configuration but the standby database shows me a lot of error simple because it's in MOUNT state. how I should configure grid control or the standby database so the errors disappear?
