Can Oracle 10g XE Database Name be Changed?

Hi all,
Oracle 10g Express Edition comes with a Database named XE.
I would like to change the database named to something like ORA.
Can this be done in Oracle 10g Express Editorion?
If have you have done this, please let me know how to do it?
- How to change Database Name from XE to ORA
- set the listener configuration to listen to ORA.
With my basic twidlings, I have come to a conclusion that Oracle 10g XE is does not support it as a feature.
Thanks,
Senthil

In order to get the smaller footprint, XE has a few administrative limitations.
Keep the name XE, or be prepared to have things in the admin tools and support environment break.

Can we rename the database name in oracle 10g

Hi,
Can we rename the database name in oracle 10g.
Please help

Yes as already said, using DBNEWID Utility can renamed the database name.
You can also take a look at the Oracle Metalink Note:429674.1 (Which was written by me) - Subject: How We Used the Oracle DBNEWID Utility to Change the Database Name

Number of available records in Oracle 10g express database

Hi,
I am facing problems in getting the number of available records in Oracle 10g express database with the following query.
string filename = dbObject.FILENAME;
string vendorID = dbObject.VENDOR_ID;
OracleCommand myCommand = _connection.CreateCommand();
myCommand.CommandText = "SELECT COUNT(*) FROM ASSET_PROCESSING_OUTPUT WHERE *FILENAME = :filename AND VENDOR_ID = :vendorID*";
myCommand.CommandType = CommandType.Text;
myCommand.Parameters.AddWithValue("filename", filename);
myCommand.Parameters.AddWithValue("vendorID", vendorID);
OracleDataReader reader = myCommand.ExecuteReader();
Using this command how can I get if the record exists in the database with the given value.
Thanks in advance.

It appears you're only executing the statement. You need to fetch the result to see the value returned by the SELECT statement.

Oracle 10g/11g database use on UEK versus Red Hat kernel? How widely used?

Greetings
is there any official or semi-official information regarding how widely used is Oracle UEK to run Oracle 10g/11g database (RAC or single-node) versus running Oracle database on Red Hat Linux or on Oracle Linux with Red Hat kernel ?
I am asking because at my customer site there is a perception that Red Hat (or Oracle Linux with Red Hat kernel) is much more widely used in production to run Oracle 10g/11g database and therefore it will provide better stability even if the performance may be somewhat reduced compared to Oracle UEK option.
So I need some sort of approximate percentage numbers of how well is UEK used in Linux Oracle community to run Oracle 10g/11g databases.
Many thanks.

The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence. Well, in my opinion, a higher market share does not reflect the quality or reliability of a product. Take MS Windows for example. Unfortunately, the reason for success is often not due to knowledge and experience, but rather due to fear and sheep effect or herd behavior.
Perhaps you can use other arguments or questions to help you to make a decision, eg.:
Oracle has a better understanding of what Oracle products require than Red Hat.
Oracle takes full responsibility for the OS and Database, no finger pointing.
Oracle tries to provide a better product than the RHEL kernel.
The Oracle UEK kernel contains Oracle driver software, not available for RHEL 6 or later.
Oracle updates are free of charge, RHEL requires a subscription.
Oracle as a company is about 20 times bigger than Red Hat.
There can be reasons that require the use of the original RHEL kernel, for instance if the vendor of a specific driver for your hardware demands it. But otherwise...

Install APEX to work on existing Oracle 10g R1 database

I want to use APEX on an existing Oracle 10g R1 database. If I install it normally with the program downloaded from your site, it installs its own database that you use.
How can I set / install it to use the existing database instead of its own database?

Hi guys,
Thanks for the info and input. Is there anybody have sucessfully done this. Most of the info that out there, the README in the patchset all pointing to upgrading the OCS, not installing the OCS on top of an existing 10g AS and DB. I'm thinking installing the OCS R2, and then patching and upgrade it to 9.0.4.2 or 4.3 and then point or move it to the existing 10AS and DB. This is where I'm quit blur at the moment.
Anyway thank for all the info.

Connect Oracle Developer / Designer to Oracle 10g XE database

I have installed the Oracle 10g XE database on my PC. Also on the same computer I have installed Oracle 10g Developer Suite (Designer, Forms etc). The database runs ok without problem. However I cannot connect Designer to the database. I know a listner program (e.g. tsn listner) has to be installed for the purpose of connecting to the database. When starting the XE database a listner program also is started.
My question:
What do I have to do inorder to have the Designer connect to the XE database?
R. Carson

Is there any changes should I do?!Well sorry but I don't know. This sugesstion to copy sqlnet.ora file resolve my problems to connect with Developer 6i to 10g, but that is 10g EE in my office, not XE at home...
Anyway your sqlnet.ora file look like very "default" but maybe is that O.K. on XE?
Who knows?

Shan,
In the same way you create user in any other oracle database. I recommned to check following Oracle Lite Sql reference document for creating user from command line.
http://download.oracle.com/docs/cd/B19188_01/doc/B15917/sqcmd.htm#sthref487
or
sql> CREATE USER liteuser IDENTIFIED BY "litepassword"; -- And add required privs to the user.

Can Oracle 10g database runs on these operating systems?

Does Oracle 10g supports working on below OS:
1) zOS
2) OS400
What is Data recovery protocols.
This is required as i was doing my research on staic data & dynamic data to be loaded. Is this can be done using Data recovery protcols.

No. If you are indeed maintaining an IBM iSeries (or AS/400) or zSeries you probably know that IBM ships it with its own DB2 database and that this database is fully integrated in the OS.

Oracle 10g R2 RAC - IP address Change

We succsessfully installed Oracle 10gR2 single database on two node RAC on Windows 2003. I followed the Oracle RAC installation documentation and assigned a public IP for the machine and another Virtual Public IP and a Private IP. We have also changed the "hosts" file in Windows to reflect the above mentioned confiuration. Here is a snippet of the "hosts" file in Windows.
xxx.xxx.xx.xxx NODE1
xxx.xxx.xx.xxx NODE1-VIP
192.168.1.161 NODE1-PRIV
xxx.xxx.xx.xxx NODE2
xxx.xxx.xx.xxx NODE2-VIP
192.168.1.161 NODE2-PRIV
After succsessful installation and testing for a few days, we are in a situation where we need to chanage the public IP's for NODE1-VIP and NODE2-VIP. If I change the IP's in the "hosts" file for NODE1-VIP and NODE2-VIP and restart the computer, both the nodes are not starting up and it comes back with a windows error. But If I change back to the old IP's, it works absolutely fine. How can we change the Virtual IP's associated for each node after a successful RAC installation?
Thanks.

Hi,
The VIP are registered as a highly available resource within the Oracle Cluster Registry (OCR).
If you want to use different VIP's than the previously configured you need this Metalink Note: 271121.1 - How to change VIP and VIP/Hostname in 10g
Be aware of the following bug: 4500688 - THE INTERFACE NAME SHOULD BE SPECIFY WHEN EXECUTING 'SRVCTL MODIFY NODEAPPS' that is not described in the mentioned Metalink note above. This means that it is better idea to modify the VIPs by explicitly specifying the network interface name, for instance: srvctl modify nodeapps -n mynode1 -A 100.200.300.40/255.255.255.0/eth0

How to start Oracle 10g RAC database and clusterware?

I have steps to stop the 10g RAC Database and clusterware but not sure about starting it.
I have heard executing
$crsctl stop crs --as root
on each node
will start the database,asm,nodeapps .Is that true?
or we have to do that step by step like we do in stopping the clusterware and database below
1.Stop the agent:
cd to $AGENT_HOME/corpng04.amhc.amhealthways.net/bin, then run: ./emctl stop agent
2.Stop the full database
$ oracle_home/bin/srvctl stop database -d db_name
3.Stop the ASM Instances on node1,node2
$ oracle_home/bin/srvctl stop asm -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name
4.Stop the NodeApps :vip,listener,oms and gsd
$ oracle_home/bin/srvctl stop nodeapps -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name
5.Stop the CRS cluster processes :those bloody 3 evmd,ocssd,crsd
$su - root
$CRS_home/bin/crsctl stop crs

Paul R @ NL wrote:
before is shutting down crs i tend to stop the instances and services via srvctl then stop crs via crsctl
just the way i do it. not saying it's the right way but it is the one i am comfortable with.Good -) If we stop CRS, but forgot shutdown oracle instances ... we'll see shutdown abort in alert log file(that mean instances are shutdowned abort).
We should shutdown instance before stop CRS anyway.
