I have two node RAC database running on linux machine (Oracle10G SE), our requirnment is to install new oracle binaries for Oracle10G EE on diffrent home location.after install Oracle10G EE binaries on new oracle home , i want to point our existing database to new Oracle10G EE home to adotp a features of Oracle10G EE features.
But at the same time i dont want to deinstall our Oracle10G SE binaries.So it is possible to rollback our process to point our database back to Oracle10G SE from Oracle10G EE in case anything going wrong.
I have Oracle 11g installed on AIX and I want to install another 11gR2 single instance in a different oracle home, will it be possible?
View 3 Replies View RelatedLately, there has been a handful of intermittent performance issues and it all boiled down to the fact that Oracle happened to choose a "bad" plan to execute them for a just a set of bind variables.
I understand Oracle must be doing it for a good reason but it just worked for us when we ensured a single plan is always used. We did it either by creating indexes or sometimes out of no other choice forcing a particular plan (manual plan).
Now, as a proactive measure, I am interested in identifying if there are more such cases. I managed to find about 23 such cases by using the query below. I am planning to regularly check the report generated by the below query.
Select Sql_Id,Count(*) From
(Select Distinct Sql_Id,Plan_Hash_Value From Dba_Hist_Sqlstat where plan_hash_value <> 0 )
Group By Sql_Id
having count(*) > 1
But before we really start addressing them I wanted to know if it is correct to consider that it is always a bad thing to happen if Oracle chooses multiple plans? I am not saying all such cases are giving problems but we did see that a handful of such problems boiled down to this case.
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 ?

View 1 Replies View RelatedThe best way to structure my schemas within a single Oracle instance to support multiple project development. At the moment, within an Oracle instance I have Area_Dev and Area1_Test schemas, with the intention that Project Xv1.0 would use Dev schema for development and Test schema for testing.
Lets say I want to start on Project Xv2.0 development while I am still finalizing Project Xv.10 development what is the best way of accommodating that, without creating individual schemas for each project?
My context on our servers is the following one:
- 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?

where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:

Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
single schema setup or multiple schema setups for an application development. Which option is recommended and pros and cons of these methods?

I have installed oracle 11g Release 11.1.0.1 on windows server 2008.I access this server from a client machine running on winXP through SQL PLUS. I wanted to shutdown and start DB server from this client machine. Accordingly i issued shutdown immediate command from SQLPLUS.
Now when i tried to start the DB with "STARTUP NOMOUNT" command i received error 12514. I understand this error means that the listener received a request to establish connections to a database but since DB services are not up and running, hence the error. So my first question is how do I resolve this error.
Continuing further, i tried to re-connect to the database as sys, and i received another error ORA-01041. So, my second question is why did i receive this error and again how can i resolve it
may be you can point me to relevant reference in Oracle documentation) how can i start and stop oracle from a client machine using SQL interface in CLI mode and windows environment and avoid this error.

View 11 Replies View RelatedWe 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.
