Heterogenous Standby Configuration - Oracle 10g

Hi All
I was searching on net to find out if a Heterogenous Standby Configuration could be achieved in Oracle Database Server 10.2.0.4.0?
We have our production Database running on Windows 2003 Server EE running on Dell PowerEdge. Its a two node RAC Database running Oracle database Server EE 10.2.0.4.0.
For this set-up, could we look at having the standby on another server running SUSE Linux. If this is possible, we would be able to proceed with out actually procuring another hardware and also make use of this Linux machine which is failry under utilised at the moment.
From your experiences, could you please advice if this is a sensible way. If such a set-up is existing, it could help from your experiences off what we could expect in terms of pitfalls and so on which you might want us to consider before making a decision this way?
Many thanks for your recommendations in advance.
Regards!
Sarat.

Agreed.. As I was goind through some other posts on the net, I understand this Heterogeneous Standby Configuration is a new feature in Oracle database 11g ...
We might also need to look at that possibility.. however, if there is a place which I could refer to and make some quick notes on such mixed OS configurations, it helps alot... I may also want to go through the 11g documentation meanwhile..

How to configure Oracle 10g to use 4GB memory

I'm trying to configure Oracle 10g to use >4GB memory. Have configured server boot.ini with required flags (/3GB /PAE). Rebooted server then created standard database, then connected to db instance and changed oracle parameters DB_BLOCK_BUFFERS, USE_INDIRECT_DATA_BUFFERS as required. Restarted DB instance, DB fails to restarted with SGA memory error. According to oracle user docs the SGA is nolonger in effect due to previous settings. Can you provide example of SPFILE with parameters settings that do work and use >4GB memory. Current server has 8GB, 2 x Dual XEON core/processors (i.e. 8 processors)

The recommended /3GB switches in the boot.ini file can only be used with the following operating systems editions (KB article 291988):
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Data Center Server
Microsoft Windows Server 2003, Enterprise Edition
Microsoft Windows Server 2003, Data Center Edition
Microsoft Windows Small Business Server 2003
Important: Windows 2000 and 2003 Server Standard Editions DO NOT SUPPORT /3GB Switch.
So if your OS is listed above, then you cannot have a larger SGA.

How to configure Oracle 10g Advanced Security to use SSL concurrently with

How to configure Oracle 10g Advanced Security to use SSL concurrently with database User names and passwords
In Oracle Advanced Security Documentation it is mentioned that i can use SSL concurrently with DB user names and passwords. But when i configure the client certificate on the client my DB connection is getting authenticated using the certificate, which out passing user id or password.
We want to connect to Oracle DB over SSL channel so that the data packets are not in clear text. Also we want the user to make a connection using user id and password.
Basically we want SSL with out authentication.

Configure Oracle 10g Forms 9i for XML

How do I configure Oracle 10g Forms 9i to compile XML code? Is there a particular configuration file I need to update with .jar files that references XML processing or parsing?
Thanks!

There is a java utility that can take an XML file that you have generated from an fmb file previously and compile it back to an fmb file.
Its called frmxml2f.bat. You'll find it in $Oracle_home/bin

Configure Oracle 10g in Netbeans 6.9

Hello,
How can we configure Oracle 10g Version of Oracle Database with Netbeans 6.9 IDE , So that we can directly connect database with the IDE

First you will need the Oracle driver found in the file ojdbc16.jar.
In NetBeans go to the Services tab and select the Databases->Drivers node in the tree. Right-click and select New Driver. Find the jar file above and it should recognize the driver class for you (if not it is oracle.jdbc.OracleDriver).
Then right-click on the Databases tree node and select New Connection. Select the Oracle driver in Driver Name and fill in the connection parameters.

How to install and configure Oracle 10g Express Edition on Fedora 11?

Hi everyone!
I have recently installed Oracle 10g XE on my Laptop Gateway T-1625, which has Fedora 11.
I followed the install instructions on [http://st-curriculum.oracle.com/tutorial/DBXETutorial/index.htm] , and configured the server as explained, but something is wrong... When I try to go to the database home page http://127.0.0.1:8080/apex, I get "Failed to Connect" on Firefox 3.5b4... I don't think it's because of the Firefox version because it's proved to be very stable (for a beta).
I've search for similar issues on GNU/Linux and I found this thread in these forums: [ http://forums.oracle.com/forums/thread.jspa?threadID=915218&tstart=0] , but the solution is for Ubuntu 9.04, and if it's possible I would like to know a specific solution for Fedora 11.
I also tried to see the oracle server status with:
# /etc/init.d/oracle-xe status
And I got this....

Hi again!
After your last post I realized that the dba group and the oracle user already existed.
#groupadd dba
groupadd: group dba exists
#useradd oracle -d /home/oracle -s /bin/bash -g dba
useradd: user oracle existsHowever, I finally assigned a password for that account and changed the ownership of the /usr/lib/oracle/xe
with the commands you suggested:
passwd oracle
chown -R oracle:dba /usr/lib/oracle/xeAfter this, I can log in as the oracle user but the SELinux showed a warning and the /usr/lib/oracle/xe
is treated as the oracle home, and no .bashrc file is located on this home. This is the SELinux warning:
SELinux is preventing gdm-session-wor (xdm_t) "write" to /usr/lib/oracle/xe (lib_t).
Details:
SELinux denied access requested by gdm-session-wor. /usr/lib/oracle/xe may
be a mislabeled. /usr/lib/oracle/xe default SELinux type is user_home_dir_t, but its
current type is lib_t. Changing this file back to the default type, may fix your problem.
File contexts can be assigned to a file in the following ways.
* Files created in a directory receive the file context of the parent
directory by default.
* The SELinux policy might override the default label inherited from the parent directory
by specifying a process running in context A which creates a file in a directory
labeled B will instead create the file with label C.
An example of this would be the dhcp client running with the dhclient_t type and
creates a file in the directory /etc. This file would normally receive the etc_t type due
to parental inheritance but instead the file is labeled with the net_conf_t type
because the SELinux policy specifies this.
* Users can change the file context on a file using tools such as chcon, or restorecon.
This file could have been mislabeled either by user error, or if an normally confined
application was run under the wrong domain.
However, this might also indicate a bug in SELinux because the file should not have
been labeled with this type.
If you believe this is a bug, please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
Allowing Acces:
You can restore the default system context to this file by executing the restorecon command.
restorecon '/usr/lib/oracle/xe', if this file is a directory, you can recursively restore using
restorecon -R '/usr/lib/oracle/xe'.
Fix command:
restorecon '/usr/lib/oracle/xe'I suppose the command #useradd oracle -d /home/oracle -s /bin/bash -g dba is where I can define the user's home, but if this user already exists how can I modify its settings?
is SELinux preventing the .bashrc file to be created? or what could be causing this?.
I hope you know how much I appreciate your help and want to thank you for your time.

Time synchoronization while configuring Oracle 10g RAC

I am installing Oracle 10g RAC on 3 EHEL5.0 systems. The problem is the time can not be synchoronized although I had already enaled the Network Time Protocol and let all the related servers to be synchoronized with the same NTP server.
I want to know why the time cannot be synchoronized on different servers?

Time synchronization with RAC is critical. Oracle will refuse to install if you do not perform this step.
You have three choices. The more risky one is to configure access to an external time server. I don't like this because it does create a path between my data server and the internet. The second is to build a time server in our data center that you reference. This is the best option as you can, and should, use that server for synchronize everything which is a great help with replication. The third choice is to arbitrarily choose one node and synchronize the other nodes with it. The downside is that if you lose that node you are at risk.
There are plenty of instructions on how to create a time server on the internet but no matter which choice you make ... you will need root privs on operating system to configure it.

Can we configure Oracle 10g xe so that it accept date in yyyy-mm--dd format

I am facing problem in inserting and updating data in oracle server through jdbc. its java.sql.Date class sends date in yyyy-mm-dd format while oracle requires date in dd-mmm-yy format. can we configure oracle server in such a way that we may send date in yyyy-mm-dd format to insert and update?

People should be sure of their information before
posting, even more so if they have an Oracle Ace
credential,as they're more likely to be believed. Not sure what you are saying.
The way I read it, Avi stated that overriding the NLS_DATE_FORMAT as an initialization parameter WILL NOT affect the way XE works, and you still need to set the parameter at the session level.
This is true.
As demonstrated here, where I
- startup my XE (SuSE 10.1 Pro/Linux),
- show the NLS setting,
- log on to a regular user, -
- show the system date,
- change the NLS_DATE_FORMAT system wide by updating my PFILE,
- restart the database
- show the NLS_DATE_FORMAT
- extract the system date.
As you see from the console session, the date still comes out in the format defined by the NLS_TERRITORY, in spite of what the global NLS_DATE_FORMAT indicates.

Physical Standby database Oracle 10g Standard Edition

Hello,
I open a new question about testing a standby database a because of this:
I realize that my standby database is 10g Standard and not Enterprise and not 11g.
Because for testing we plan to modify data on Standby, we are looking for some way to restore Standby to the point before testing.
So, I can't use Flashback Recovery Area for restoring my database to a certain point after testing.
In this scenario, the only way that I think is:
On Standby
- Shutdown database
- Copy by O/S all datafiles, temp files, control files and redo logs. That will be my backup before testing.
- Open database, test and modify data
- When test is finished, shutdown database
- Copy and replace by O/S all datafiles, temp files, control files and redo logs from backup place
- Open database as standby and apply all archived redo logs needed.
Would be it work without problem or should I copy other files?

it comes under Refresh of database, use --> cleanup --> restore.
If its enterprise edition , you can use procedure mentioned in this note How To Open Physical Standby For Read Write Testing and Flashback [ID 805438.1]

How to stop and cancel physical standby database (ORACLE 10g)

Dear All,
I have physical standby setup and I want stopped for the time being that to use the database as an normal DB (standalone inestance).
Kindly advise and show me how do I do that.
Regards,

executing below query on primary db stops log shipping to standby.......i think this is sufficient for disabling your physical standby setup temporary
alter system set log_archive_dest_state_2=defer scope=both;
In future if you want your dataguard setup back..............you can rebuild the standby and enable the log_archive_dest_state_2 parameter.
