Server Administration :: ASM Instance Did Not Access Raw Devices
Sep 28, 2011
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:
- 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.
database administration , we are planning to use amazon cloud database , this database does not allow us to login to server machine , unfortunately amazon don't provide ssh to this machine , in general for doing any of adminstration task on the database will there be need to log into the machine ? we can always log in through toad or any other sql client but we cannot do ssh to server..general can this limitation effect administration ?
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.
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?
I'm currently working on a project in which I do not have permissions to access the Server where the database is installed and configure.Because of company policies, I do not have Admin Rights over Oracle, but I do have an account that can make Selects to DBA_USER_PRIVS for instance.
I would like to know if there is any way to access the database logs to know if there was any kind of problem within the database, because one of my Schemas misteriously went clean (all tables, sequences, triggers, ... vanished)
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 need to create one to many user DB link in oracle 10g. Meaning I have a user A in database 1 and I want to access the objects from user B,C,D in database 2, how to create a public database link so that i can have this one to many user access?
I have login through the sysdba and created dblink and modified the tnsnames.ora for necessary changes. And the it started working correctly and I can able to get the data by selecting it.But when I login with different user that is showing the following error.
ORA-12154: TNS:could not resolve the connect identifier specified
How to resolve this,is there any privileges or permission need to give to that 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."

I want to get clear with one thing yesterday i installed oracle9i and dev 2000 to my client.
when they run one report they got stuck with pl/sql compilation errorrep-1247
when i checked that report in the report builder, in the query they are using some other table which is not belongs to that schema,then I give that schema.tablename and compiled, but this is coming for other reports also, then only i came to know that they are acceessin other schema also, how can i sort this out.
can i fix this by givin full access privilige or what privilige can i give to get full access of other schema table.
how can i check in the old database what are all the roles and privileges given to this user,
We had our production database hosted on Oracle 9.2.0. Few months back we have migrated it to Oracle 10.2.0.4.0. After Migration I have noticed that redo generation has become very very high. In earlier case no. of log files generating in production hours were around 30 where as after migration it become around 200 files per day. I have run statspack report on this database. Report is saying that db block change & disk write is become very high. Parameter timed_statistics has also been set to FALSE. Even then there is not any reduction on no. of log file generation. I had used import export for upgrading the databases.
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.
I am facing a strange issue on 11gR2 (OEL 5.4) standby readonly with apply database.It's throwing 16000: database open for read-only access during SELECT's .
Here is snapshot of errors.
ORA-00604: error occurred at recursive SQL level 1 ORA-16000: database open for read-only access
We have created a new db link. But we are not able access the remote database. When we are trying to access any table using db link system is getting hanged.
We would like to know what are the parameters/permissions which affect the db link access either at data base level or at server level.
One observation we made is that that particular db link is not getting dropped when we tried to drop it.
