Server Administration :: Instance Name On Imaged Server?
Sep 22, 2010
We imaged production Oracle Server ( OS and Oracle and everything) to a backup server. I guess my question shall be how do we access the local instance via this backup server. When we log on to this backup server, we ran sqlplus and connected to the instance but it ended up to connect to production instance. Shall we stopped local Oracle services and change init.ora, tnsname, or listener files in order not conflict with production instance?
- one ASM instance - X DB instances - each DB instance uses 2 or more dedicated diskgroups from the ASM instance - there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view - the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?
We performed image copy of production Oracle server (OS and instances) to a backup server. After a few weeks, we try to restore a latest Oracle database backup from production server to backup server. As we know, Oracle instance must be unique on the network.
Even we log on to backup server and bring up the instance, I think that still point to production instance since all init file, TNSNAMES.ora and listener file are still same. If we restore the database, we will end up bring down the production instance and restore on top of productions. How to change instance name on backup server including TNSNAMES, sqlnet, listener files in order for us to restore Oracle database from production to backup server?

What seems to be a problem here? I've been trying to fix this for few weeks.
How to create DBMS_SCHEDULER job for particular instance,we have 3 instance we want to schedule few jobs in Instance 2,how to schedule in Particular instance.
I've to install Oracle 10g on Solaris 10, Sparc. I prepared anything successfully, but, when I gone to create ASM instance, I found the Create new bow did not show any disks into. I take brief something:
I am trying to configure a new ASM instance. I am getting error " -bash: crsctl: command not found" .. where should i actually look for the error. crsctl command not found.... I am doing this as a root user .
I want to install oracle 11.2.0.2 single instance database on AIX 6.1, does oracle recommend separate OS user for grid infrastructure and for oracle install? how many groups I need to have for these users like oinstall, dba etc?
I have a lot of shemas inside an instance... How to organize them?
What I see is a long list of schemas which could be difficult to manage if number of schemas grows up... For example, I'd like to group Schema_1, Schema_2 and Schema_3 in something like Group_1, so it could be seen more organized.
Group_1 Schema_1 Schema_2 Schema_3
Sometimes a java or .net application uses 3 or 4 schemas... these schemas are in the same instance which has other schemas for other applications.
create an ASM (Automatic Storage Management) instance using dbca. At first try I mistakenly skipped the part where I click on ASM Parameters to add /dev/raw/raw* as my asm_diskstring so it created an ASM instance. When I get to the next page ASM Disk Groups, I selected Create New and I did not have the desired display, because of the step I missed.
I went back to do some cleaning up as follows:
1) Edit the oratab file to remove the ASM entry
2) backed up these files by renaming to old-<filename> old-ab_+ASM.dat old-hc_+ASM.dat old-lk+ASM old-orapw+ASM old-spfile2+ASM.ora
Now when I try to go through the steps to create an ASM instance, at the point after I enter my ASM Parameters, I get the following prompt:
"DBCA will now create and start the ASM instance. After the ASM instance is started you can create the diskgroups to be used as storage for your database."

BTW I have not set $ORACLE_HOME, $ORACLE_BASE, $ORACLE_SID yet.
Find an appropriate script to automate Oracle DBs in one server? This db server have 6 instances. We always done the starting up and shutting down manually, although we have a reference script that does this but in Oracle v7.3.4. We do want to include the automatic start/stop of dbconsole for accessing it via OEM.
We have Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production on AIX platform. We've noticed that the CPU usage on the server is slowly but steadily grows since instance restart: after the instance restart the maximum CPU usage is about 25-30%, and a month later with the comparable transactional load it's about 60-65%. In the top I see a lot of Oracle sessions each of which use about 1% of CPU, so I cannot find the one "CPU eater".
i am trying to install Oracle 10.10.2.0 on Windows Server 2003 standard x64 Edition Service Pack, but when i try to run the installer or open DVD it gives me below error.
"The image file D: is Valid, but is for a machine type other than the current machine."
I was trying to delete the database in the test server. When i was deleting listener was already stopped, i continued deleting using dbca, it shown me some alert that datafiles cant be deleted because system could't find database, since listner was stopped so only service was deleted(the one showing in the windows administrator toolsservicesOracleServiceTEST).
All the datafile parameter files are still there. How can i delete the datafiles and parameter files belongs to that database or how to create the deleted service, so that i will start the listener and do the complete deleting of the database.
I have to migrate production database version 10gR2 on windows 2003 server to oracle 11gR2 on windows 2008 server . So far i have just installed the oracle software on 64bit windows 2008 server. How to move the data or migrate from old server to new server .
after a long time,(i never remember when was the last time i installed 9i)i was asked to install 9i.So, whether i install server or cilent i get this error <attachment>
after i ignore it and finished the installation,The server installation gets abruptly ended for the client i get TNS errors.
We are planning to consolidate our Oracle Production DB into one server. We are basically a windows shop. Is it feasible to run 8 production Oracle DB in one windows server. All the DB are not really transaction intensive DB. 2 DB in the size of 300GB and others all DB falls under average size of 40GB.
I can take care of the HD slicing so Oracle does not enter into IO bottleneck. We are planning to go for external NAS or SAN for storage.
My main concern is on processor usage. The processor we are thinking about is Intel Xeon Quad Core x 2nos. Will there be a processor bottleneck or is there way in Oracle to assign processor usage(I belive there is no much tweaking options here)
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
I have database in single server. I already have ORACLE_SID=stagedb. So i want to create new sid and named as proddb.Is it possible have multiple db in single server? This server not running as RAC. It run as single only.
