DR on different Oracle binaries

Dear DBA,
our production database is 11gR2 (RAC) installed on HP-Itanium processor and we are planning to install the DR server (dataguard physical standby database) on HP- PA-Risc processor.
this installation requires 2 different Oracle binaries (one for the Itanium and the other for the PA-Risc).
do you think that it is feasible ? or the binaries should be the same ?
thx in advance
Elie

Hi,
It may work as PA RISC and ITanium Server has the same endian so you may be able to setup DR between Itanium and PA RISC server. You may have to test this though before setting it up for a production database.
There could be some unknown which may cause issue later during several failover/switcher senerio that you have to make sure that it works. I know that datafiles can be copied from PA Risc to Itanium to set up another database without any issue due to both using same endian format.
Regards

Oracle binaries hanging

I've installed Oracle Client 10GR2 on Red Hat Enterprise Linux AS release 4 (Nahant Update 2).
But oracle binaries like sqlplus, imp, exp are hanging.
I've set ORACLE_HOME correctly. I've tried running sqlplus -VERBOSE but this hangs as well.
Any idea what could be the problem?

Am running Oracle 10GR2 on Red Hat Enterprise Linux ES release 4 (Nahant Update 5).
No problems with connectivity. Database instance is running fine and so are the client binaries.
There were some issues like installing/enabling kernel async_io - but these would only be applicable if you're trying to run an Oracle instance.
Are you connecting to a local instance, or are you using a network connection?
If a local connection, SQL*Plus will (via OCI) launch an oracle process from $ORACLE_HOME/bin and attached itself to it. That process will be the dedicated server process for SQL*Plus.
If a network connection, SQL*Plus will open a tcp connection (via OCI) to the Oracle server platform.
Obviously, "hanging" when connecting means a very different software layer for each.
You will need to supply some more detail. A copy and paste of the actual ssh/telnet session that hangs, the environment settings (ORACLE_HOME, TNS_ADMIN, ORACLE_SID, etc), and details of the type of connection (if a network connection, the TNS alias definition), and so on.

Is it possible to change the location of Current Oracle Binaries to another

Hi,
Can any one let me know the procedure if any for the following Scenario?
I have my Oracle binaries let say in /u01 now i want to move it to /u02
Thanx in advance..

oracle binaries are residing in bin directory of ur oracle instance.
say u have oracle instance running in /u01 and also the same oracle instance running in /u02, then u can move ur binaries to a different location. binaries are like pointers on the database which are used for routing the connection calls.
this is to be done by shutting down all the servers properly.

Re-installing Oracle binaries - Best option?

Oracle binaries are corrupted and we are preparing to re-install the binaries - I need help in selecting the best possible option with minimal downtime
1. Install Oracle in a different Oracle home and rename to old one
for ex: install in /opt/app/oracle/product/10.2.0/oracle_NEW and rename the folder to /opt/app/oracle/product/10.2.0/oracle after installation is complete.
2. Install Oracle in a different Oracle home and copy (or tar) the files to old Oracle home
3. Install Oracle in different home and move the database to new Oracle home - I know this method works, but we dont want to use this method as we want to maintain the consistency between all nodes - we have 4 more clusters that has the same directory structure and we would like to use the same structure for easier maintenance (like scripts)
4. or any other option you think of with a minimum downtime.
Please advise,

How did Oracle binaries got corrupted?
I recommend you to do the following
*1. take backup of your database*
*2. shutdown instance and listener*
*3. and install oracle binaries in the same home and make sure you are installing same version.*
*4. Startup database instance and listener (test everything and open it up for everyone else).*

How do you join two tables from different Oracle schemas using a subquery

I am trying to join two tables from different Oracle schemas using a subquery. I can extract data from each of the tables without a problem. However, when I combine the select statements using a subquery I get the Oracle error *'ORA-00936: missing expression'*. Since each SELECT statement executes on its own without error I don't understand what is missing. The result set I am trying to get is to match up the LINE_ID from PDTABLE_12_1 in schema DD_12809 with the MAT_DESCRIPTION from table PDTABLE_201 in schema RA_12809.
The query is as follows:
sql = "SELECT [DD_12809].[PDTABLE_12_1].LINE_ID FROM [DD_12809].[PDTABLE_12_1] JOIN " _
+ "(SELECT [RA_12809].[PDTABLE_201].MAT_DESCRIPTION " _
+ "FROM [RA_12809].[PDTABLE_201]) AS FAB " _
+ "ON [DD_12809].[PDTABLE_12_1].PIPING_MATER_CLASS = FAB.PIPING_MATER_CLASS"
The format of the query is copied from a SQL programming manual.
I also tried executing the query using a straight JOIN on the two tables but got the same results. Any insight would be helpful. Thanks!
Edited by: user11338343 on Oct 19, 2009 6:55 AM

I believe you are receiving the error because you are trying to JOIN on a column that doesn't exist. For example you are trying to join on FAB.PIPING_MATER_CLASS but that column does not exist in the subquery.
If you want to do a straight join without a subquery you could do the following
SELECT DD_12809.PDTABLE_12_1.LINE_ID
,       FAB.MAT_DESCRIPTION
FROM    DD_12809.PDTABLE_12_1
JOIN    RA_12809.PDTABLE_201    AS FAB ON DD_12809.PDTABLE_12_1.PIPING_MATER_CLASS = FAB.PIPING_MATER_CLASS HTH!

URGENT HELP!!. Applying 8.1.7.4 patch in different Oracle Homes.

Hi all,
We are using 8.1.7.0 on SunSolaris OS(5). We've 4 oracle instances running on 817 and one on 8174. They are all in different oracle homes.
Oraclehome1 - 8170
Oraclehome2 - 8174
When I tried to put 8174 patch on Oraclehome1 the installation terminates without installing the software and its not giving any errors. In oracInventory logs it displays the following version numbers.
8.1.7.4 > 8.1.7.4
I also tried to reinstall full software on Oraclehome1. It is also failing with link errors.
How can I install 8174 patch in oraclehome1? OR how can upgrade the oracle instance under oraclehome1 to 8174?
Thanks for any inputs.
Regards

Yes I did shutdown the database and stopped all other services running on the machine.

Oracle 9i and Oracle Forms 6i in 2 different Oracle-Homes

My OS: Windows XP
First I installed "Oracle9i Database 9.2.0.1.0" with Oracle-Home-Path "OraHome92".
Then I wanted to install "Oracle Forms Developer/Services 6i Release 2", because I need to use the Form Builder. I wasn't able to install this in the same Oracle-Home, so I installed it with a new one called "oradev". Now my Oracle Installation-Folder looks like this:
-oracle
---admin
---ora92 (comment: HOME 0)
---oradata
---oradev (comment: HOME 1)
Working with the database directly works fine, with Enterprise Manager I created a user, database and my first tables. No problems there.
But now I do have a problem: When I try to connect to my database with Form Builder, I get the following error message:
ORA-12154: TNS:Der Dienstname konnte nicht aufgelöst werden.
In english it should be this:
ORA-12154: TNS: could not resolve service name.
I guess the problem might be the two different oracle-homes?!??
Does anybody have an idea how I can connect to my database with Form Builder?

How can I do that?Use Oracle Net8 Easy Config utility (Windows menu).
I try to connect with the user I created with
Enterprise Manager.When you connect to DB you use a username, a password, and a connection string. The last one (a TNS alias) is necessary because you're working in a different Oracle Home, it's the same as you were on a different machine.

How to synchronize two different oracle designer repositories

Hi
we have the following situation
we use Oracle designer and SCM repsository to manage our datamodels and server models.
we have two teams working in two different locations. Both teams are working on the same datamodels/ server models.
issue is , the network speed is slow between the two locations, so we dont want to use same instance of SCM repository (or in other words same oracle database server) to manage work.
is there a way/Tool , whereby Both teams can work in separate repositories at their respective locations (i.e. on two different oracle servers ) and we keep transfering the changes (deltas) between two repositories to keep them in sync ?
Tia and Regards

You might be able to use a database link to connect from one db to another.

Can't Create TNS-connections for different Oracle Homes

I've installed Oracle 9.2 client and also the Oracle XE 10g Database on my computer. So there are two files "tnsnames.ora"
(C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN, C:\Programme\ORA92\network\ADMIN). By creating a new connection with
"TNS" option there is only the content of the XE-tnsnames.ora file. How can I choose the tnsnames.ora in Oracle 9.2 Home?
Edited by: @chris on 15.05.2009 15:54
Is there a preference for SQL-Developer to choose any installed Oracle Client?
Is there a file where I can configure a different Oracle Client for SQL Developer?
Remark: My "Windows XP - Path" settings are: C:\Programme\ORA92\BIN;C:\oraclexe\app\oracle\product\10.2.0\server\bin;...
Edited by: @chris on 03.06.2009 19:12
No comments since 2 weeks :-(
So I think there is no possibility to select an installed Oracle client when creating "connections" in SQL Developer.
Would anybody else like to have this feature in future releases of SQL Developer?
PS: In "SQL Navigator" (by Quest Software) you can select your Oracle Client when creating a connection.

I had this same issue only with SSMS 2005 x86.
I unchecked the "Allow inprocess" and I was able to connect.
You will need the security "Be made using this security context" with the U/P that you mention
"+same userid and pwd which I use in SQL* Plus to connect to same oracle database+"
Hopefully you will get pass that issue. The issue I have now is that I can't do a select on
one of the linked tables.

Oracle Intelligent agent in different oracle home

Hi All,
We have installed new agent (9.2.0.1) in different oracle home, as previous intelligent agent(in main oracle home(9.2.0.5) where database resides) was hanging, after that we are facing a new problem in discovering listener and database in OMS server.
We have setup the ORACLE_HOME variable to new oracle intelligent home (where we have started the agent now),and TNS_ADMIN variable to main oracle home(database resides) even then snmp_rw.ora and snmp_ro.ora files are not creating in the current oracle home.I followed the metalink notes, even then it couldn't help me.
From the OMs we can discover the node, but we cannot discover the listener and database, Can anyone help me in discovering the database and listener in the oms when we have two separate oracle homes.
This is kind of urgent, appreciate if anyone can answer it as soon as possible
Thanks,
Riah

Can any one help me please ?

Can you please let us know that what needs to be done so that I will be in sync
If I am not wrong then there is command like relink
Please suggest>???

Different Oracle versions Replication?

Hello,
We want to create a replication in our laptop.
The server has oracle 9i rel.1. In the laptop we want to install oracle 9i rel. 2.
Can we replicate part of the database using different Oracle DBMS versions?
As a comment: The replication is SDE information.
Thanks,

Specifying Different Oracle Drivers

I'm having some issues using some Oracle drivers versions in different applications that use different Oracle versions (8 and 9), is there a way to define for one Connection Pool one version and for another a different one but still have XA support?
Thanks,

I would do everything you need to do to use the 10.2.0.3 thin

DBConnect with two different oracle versions

Hullo folks,
I've been looking for threads concerning the use of SAP BI's DBConnect tool with multiple external oracle databases.
My client is currently using BI 3.5 and we have successfully used DBConnect to extract information from an external Oracle 9.2.0.5.0 database (btw BW uses the same oracle version).
Currently my customer requests to extract information from a new external non-sap application. This application will be using an oracle database as well, but it will use the latest oracle version, 10.
I know that in the past it wasn't possible to use DBConnect with different oracle versions as the differences were to big. I wonder whether this is also the case with the oracle 9 and 10 versions. Would it be possible to use both versions and extract the data with DBConnect? Or are the changes too big and SAP BW can only pick one of these versions? Perhaps there's a workaround? I don't know, and I'm hoping some of you know something.
Thanks in advance.

Thanks for your answer,
though this doesn't answer my question. Yes, I know I'll have to create a different sourcesystem for the new oracle database.
However, I can only use one ini file for Oracle in DBConnect. In the past it wasn't possible to have active connections with different versions of oracle databases (you can only have one file for oracle installed in DBConnect).
The question is, whether it's possible to have a connection with two source systems where one uses Oracle 10 and the other Oracle 9... and if it's possible which file should be used in DBConnect...

Oracle binaries in rwx-r-xr-x mode

Hi,
Currently I had a database which contain highly sensitive information/data. I had discovered that all the oracle binaries in the oracle home are in rwxr-xr-x mode. After auditing by auditors, they questioned me why the binaries are in rwxr-xr-x mode, they claimed that it will increase the risk of unauthorized access and system down-time. Below are my queries:
1) Have check with oracle support that rwxr-xr-x is the default mode upon installation.
2) Can an os user who does not belong to dba group execute the oracle binaries? Althought the binaries others group are given r-x but i believe certain library access are needed? Am i right?
3) Anyway to justify that oracle binaries need to be set as rwxr-xr-x?
4) Will it poses any security vulnerability/threats to the database?
Thank You. Any comments or advise are welcome.
Your help are greatly appreciated..

Your help are greatly appreciated..Actually, the binary called 'oracle' MUST be "rws r-s r - -" for Oracle to work properly.
If it is not set like that, there is a good chance that the root.sh was not run at the end of the install. Similarily, the rest of the questions support that root.sh was not run.
Offhand, I'd guess you have a bad install.
