Two Oracle Instances

Hi,
We had a SAP Netweaver engine (ABAP stack) installed with Oracle 9i in a server. We wanted to install XI instance in the same machine. So we installed the XI instance with a new Oracle 10g database. Now, we are not able to start the old Oracle server. However we are able to start and stop the new Oracle database.
Can multiple Oracle instances can be installed in the same machine?
Regards,
Venkat

Hi,
yes, they can.
But you have to take care about environment variables.
You have to move Oracle related from system environment variable %PATH% into the %PATH% of corresponding SAP (<sid>adm) user for corresponding Oracle.
Sample:
System Path: ...c:\windows\system32... %OHOME10%\bin;%OHOME9%\bin....
Correct:
System Path: ...c:\windows\system32... - nothing related to %ORACLE_HOME% here
<sid1>adm Path: ... %OHOME10%\bin... etc
<sid2>adm Path: ... %OHOME9%\bin... etc
Then login under <sid1>adm or <sid2>adm correspondingly and make your admin activities.

RHAS 2.1 with two oracle instances

Hi all,
I need to install two Red Hat Advanced Server boxes with an external Dell RAID Storage. The pourpose of this installation it is to have two oracle instances in high availability. Is it posible ?? Where I can find documentation about this ??
Thank you and sorry for my bad english

Hola
Espero que hables español.
Si, si puedes, pero debes de tener cuidado al manejo de los disco.
Ignoro si LRH AS 2.1 maneje el concepto de Cluster FileSystmes o bien el de Cluster HA.
Te recomiento que instales dos ambientes completamente independientes de HR, co sus herramientas y BD separadas. asi podras mantenerlo mejor.
Si manejas el HA de LRH, define con cuidado las reglas y no olvides los concurrents y listeners.
Espero que esto te ayude, en caso de que tengas preguntas, no dudes en buscarme
Suerte.

Question on Oratab file when installing two Oracle instances in one machine

OS: AIX 5.3
DB version:10.2.0.1.0
I already have an instance of version 9.2 which is very important and which we don't want to upgrade and we wanted another test(unimportant) oracle instance called testdb_10gR2 of version 10.2.0.1.0 on the same machine.
So i installed 10.2.0.1.0 on a different ORACLE_HOME .Installation of the new 10.2.0.1.0 (testdb_10gR2) went ahead successfully and at the last step i have to log in as root and execute root.sh
I entered 'n' for the options "dbhome", "oraenv", "coraenv" as shown below so that the settings for our 9.2 instance (which is very important) will remain intact.
What would have happened if i entered 'y' ie. Overwrite ?
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u04/testdb_10gR2_Feb2009
Enter the full pathname of the local bin directory: [/usr/local/bin]: /usr/local/bin
The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: n
The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: n
The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: n
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
During installEdited by: Citizen_2 on Jan 30, 2009 5:05 AM

'dbhome','oraenv','coraenv' are sripts used to set a proper environment (see the descriptions at the beginning of these scripts). These scripts rely on oratab (they check for existing SIDs), but answering 'Y' does not mean you will modifiy an existing oratab.
I think these scripts change rarely, so it's very likely overwriting the existing 9i scripts with the 10g scripts changes nothing. To be honest I don't use the scripts , so in my case 'Y' or 'N' doesn't matter. But important is you don't have to worry about 'oratab'.

Best approach to transfer and transform data between two Oracle Instances

Let me first preface this post with the fact that I am an Oracle newb.
The current problem I am trying to solve is how to quickly transfer data from a customers legacy database into a new normalized destination that is modeled differently than the legacy data. So, the data not only has to be transferred, but also transformed (into normalized tables)
We have discovered, the hard way, that reading the data using a C++ application and performing inserts (even with indexing and constraints disabled) is just way too slow for what we need. We are dealing with around 20 million records here. I need to determine what the best approach extracting this data out of the source and inserting it into the destination. Any comments or tips are greatly appreciated.
Note: I have read about SQL*Loader and mentioned it to management, but they seem resistant to this approach. It's not totally out of the question though.

Oracle has a lot of technologies that fall under the general heading of "replication" to choose from. Going from a database to a flat file and back to another database is generally not the most efficient solution-- it's generally much easier to go straight from one database to another.
Oracle provides materialized views, Streams, and Change Data Capture (CDC)-- any of these would be able to give your new system incremental feeds of data from the old system's data and could be used by whatever routines you write to transform the data between data models.

Two OracleDatabase Instances on OracleWDB

Hi Guys,
Is it possible to have two Oracle instances using the same port on Oracle WebDB.
Thanks

What problem are you having?
You should be able to use DBCA to create another database called F11. Am I missing something in your question?

Reg: How to automate updation of tables between two oracle DB Instances

Hi All,
I have a requirement to auto update the tables between two oracle database instances. What are the possible solutions to handle this kind of situations.
Please help me out in identifying the correct solution.
Thanks in advance :)

The possible solutions are outlined in the distributed database documentation
They are
a) trigger (6.0 and higher)
b) advanced replication. Creates triggers on every table. Requires every table to have a primary key (8.0 and higher)
c) Streams (Uses logminer, has no impact on table. Requires every table to have a primary key, or supplemental logging will be used. (9.0 and higher)
d) Change Data Capture: superset of Streams (9i and higher).
If you don't require realtime updates you don't need c or d. b is difficult to manage. Using a) the source db can potentially have to wait for the target db to complete it's transaction.

HTMLDB as Partner Application to TWO OID instances - Authentication Schemes

For reasons I won't go into here, we have TWO Oracle OID/SSO instances running - independently.
I am interested in having HTMLDB / APEX applications capable of authenticate against either one. (one at a time, but on the same engine installation)
We have done the PARTNER APPLICATION registration which works well against one of the OID instances. Records have been entered into the WWSEC_ENABLER_CONFIG_INFO$ table and everything works as expected.
What option do I have to register the HTMLDB engine with a SECOND OID/SSO as a partner application and then allow the developers the ability to choose which authentication scheme applies?
What I have observed is that the package given (custom_auth_sso) has built in
g_partner_app_name varchar2(2000) := 'HTML_DB';
Is it possible to duplicate that type of functionality, or is there something deeper ingrained into the engine that I do not understand?
Regards,
Tim

Scott,
I am working under a model similar to your case number two.
Application 1 uses OID A
Application 2 uses OID B
I am going under the assumption that if there were two records in the config_info$ table, that I would need some type of ability to inform the WWV_FLOW_CUSTOM_AUTH_SSO package to switch between them.
I guess what I am missing is the mechanics. I am trying to avoid having to re-write the WWV_FLOW_CUSTOM_AUTH_SSO package by hand. Besides the package body being compiled, I do not know how that authentication scheme is called by HTMLDB/APEX. I have been using the Oracle Application Server Single Sign-On (HTML DB Engine as Partner App) scheme. This leaves most of the Authentication scheme pretty blank with the exception of the Session Not Valid URL ( populated with PORTAL_SSO-) and the logout URL. Magically it works though.
If I had TWO schemes registered in the config_info$, how would I indicate which scheme to use?
Do I have the capability of working with what has already been provided, or am I destined to writing a custom scheme because of the decision which needs to be made?
Many thanks

Dual oracle instances on a single server

can a server run two different oracle instances which are two different
versions oracle?
That is,one instance in 7.3.4 and another in 8i!
first of all is it possible that we have 2
installations of oracle in
the same server??
pl advise.

Thanx for this reply.
Can you also please tell me as to what would be the sufficient system resources?
Masy be you can share your server config info if that's allright.
Regards,
Subbu
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Sam ():
Yes it's possible. I'm running 8.0.4 and 8.1.6 64-Bit versions on the same server. You have to change the environment variable when you log into svrmgrl to access the databases. Other than that it shouldn't be any problem. (Provided you have enough system resources)

Two Oracle databases on one AIX Server - Note working, Pls Help

Dear Friends,
I have installed Two SAP systems with Two Oracle Databases on one AIX machine, The Installation of both the systems went fine without any errors, and also i have been able to login to both the systems seperately. (that means i cant start both the systems at a time, its one at a time)
But the problem is of the Oracle Listener, i am not able to start both the systems with single Oracle Listener processes(tnslistener). I tried all the possible scenarios as mentioned in note 98252 but nothing seems to be of any use so far.
the thing is i can start either one of the SAP Systems, But my objective is to start both the SAP Systems with one listener processes (LISTENER) and one listener port (1527)
Or
you can say i am also ready to keep two different listeners for TWO seperate Oracle databases, I tried doing so as per one of the sap notes in which you have to keep different names of listener and different numbers for listener port for second ORACLE database. I tried doing exactly mentioned in the note but yet unsuccessful...
Now i am completely lost as what is to be done since its critical i want you to immediately look into it and suggest me the appropriate solution so that i can set up both of my DEVELOPMENT and QUALITY system running...
To troubleshoot this if you require anything from my side then please feel free to ask me since our functional consultants have to soon start working on the SAP systems.
Regards
Ayush

The note you specified talk about 2 database instances not 2 databases... (I was starting to wonder how you deploy 2 databases), you can have multiple database instances on a DB. The note also give you detailed explanation of the configuration of listener.ora
Now, if this is the case and you have installed 2 instances (not databases) on the same host and configured the listener according to the note, then you should be able to call R3trans -d from both SID's.. if the R3trans fails please post the contents of trans.log here.
the thing is i can start either one of the SAP Systems, But my objective is to start both the SAP Systems with one listener processes (LISTENER) and one listener port (1527)
Then, the configuration of your listener.ora file must be incorrect.

How much pain does registering two Oracle Testing Id Cause to everyone?

Reading the forum over the last 8 months or so seems apparent to me that if a candidate has two (or more!) Oracle Testing Id's and takes exams under both then problems will result as certifications will not be generated untill all pre-requisite passes are under the same Oracle Testing Id. (For those having taken exams under Prometric their Oracle Testing Id has been set to their old Prometric Id.)
the pain this caused in the old Prometric days is mentioned on the Oracle Certification Blogs Here [http://blogs.oracle.com/certification/2008/09/one_plus_one_zero_when_it_come.html] (dont follow the procedure there .. its out of date).
The procedure for sorting this still remains a merge, however now through Pearson VUE. The procedure is not directly on Support FAQs [http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=82#5Q1A] though would indirectly be covered by (I have not received my success kit what do I do?). The procedure required is however authoratively mentioned at {message:id=3923313}. However as can be seen in the rest of the thread {thread:id=991553} there appears to be occasions when some Pearson Personnel VUE appear to not realise they are responsible for initiating the merge and sometimes the merge man may be on holiday (or maybe off on stress through the number of merge's perhaps?)
Thus the candidate with two Oracle Testing Id's has a possibility (maybe even likelihood) of pain further down the line in getting it sorted. But as far as I am aware it is usually sorted ... though it may take a while. Pain to Candidate.
Oracle and Pearson VUE have pain through this as well. There is a support cost dealing with the Oracle Testing Id Merge. Not just in authenticating and performing the merge but also when the query comes as a problem but the root cause is found to be multiple Oracle Testing Ids. While this does give support teams an opportunity to perform the net effect is increased costs for Oracle/Pearson VUE - which means reduced profits or perhaps more likely increased exam costs for everyone - in other words a pain for everyone.
Basically no one wins on this.
Why does it happen? I'll exclude why people have had multiple Prometric Id's (Oracle Testing Id's) for exams taken under Prometric. What was done under Prometric has been done.
However under Pearson VUE why might this happen?
If I start off at the linke [http://www.pearsonvue.com/Oracle] - Click on My Account - then the Link Create a new web account a form is presented:
The key part of this form is in the Previous Testing History Frame :
Please provide the following information.
     Have you tested with Oracle Certification Program before?
     (*) No, this will be my first time testing with Oracle Certification Program.
     (*) Yes, I have tested with Oracle Certification Program before.
           Enter your Oracle Testing ID, if available:If people answer NO to this question and subsequently then need/request an Oracle Testing Id Merge in my opinion they should be charged for this. This is a blatant mistruth. I suspect some people may rush to get regsitered and take the exam and or care about the registration details; or are happy for it to be sorted afterwards rather than getting the Oracle Testing Id. Sorted now.
HOWEVER:
- There needs to be a further email just in case they has the wrong button selected by mistake, so after registering the fact there has been no oracle testing needs to be confirmed. I believe, because of form design, there may be a signifcant chance of this happening.
- There also needs to be indications that if two Pearson VUE Oracle Accounts have been created then subsequently different exams have been passed on each then merging will incur a cost. This is just slopiness by the registrant.
If the people answer yes; but make a mistake in the Oracle Testing Id, they hopefully that would be picked up.
IF people answer yes, but leave the Oracle Testing Id blank, hopefully Pearson is on top of getting it sorted and not let the issue propogate. The effects of leaving this blank as unclear to me, and I hope good procedures are in place for handling it.
There is also IMHO a big issue here that it is not obvious from this page that canididates should enter their old Prometic Testing Id here.
+++++++++++++++++++++++++++
In summary I believe people having mulitple Oracle Testing Id's hurts us all, and to prevent this I would suggest a charge for merge where a candidate have incorrectly siad they have not done Oracle Testing before and where they have a had clear chance to correct this in the event the relevant form radio button has flipped without them noticing.
But I also believe Pearson VUE could probably do a couple of minor changes to procedures, pages and boilerplates to reduce the chances of problems occuring. I think some problems could be stopped before they start.
Notes:
(1) Any pages referenced are by myself from UK at time of post. Sometimes from other countries they can be different

I'd just like to add to this that one poster {message:id=4029960} appears not to have given a Oracle Testing ID when registering with Pearson VUE and that Pearson VUE appears to have located it for him. I assume he indicated he had tested previously and presumably his profile details matched those held by Oracle from Prometric. This appears to be a single (unverified) instance of this working correctly; and the candidate not ending up with multiple Oracle Testing Ids'.

Borra los archivelog mas viejos, y que ya los tengas en un backup y asi no habra problema te recomiendo tener un espacio en disco minimo de 50%I hope this is what you meant,

Two oracle homes on linux !

Hello !
Can we make two oracle homes in Linux .
In one home i have to install 8i database and in the other home i have to install 9iAS.
What i think is , for two oracle homes in linux u need to make two oracle users first ,and in two different bash_profile file u have to give the path of oracle home. So this thing will not allow to start
your database every time. u have to change user every time and then start your database .
This thing will create problem .
I have tried this thing on NT and it worked . I mean i made two oracle Homes and on one home i installed 8i and on other home i installed 9iAS. and it worked uccessfully.
How can i do it on Linux .
Regards
Seemab

No you don't need a separate user. Just a shell script to change the environment.
This is fairly standard on all unix platforms and is covered in the manuals, generally you run .oraenv or .coraenv which is really just a shell script which resets the environment.(theres probably a bash shell script for linux I haven't checked). However you can write your own to suit you needs. Generally the format is that the script it prompts you for an instance name and sets the environment approppriately but it could prompt you for anything.
for example
echo "which environmnet do you want"
read OENV
case $OENV in
9) ORACLE_HOME=....
ORACLE_SID=....;;
8) ORACLE_HOME=....
ORACLE_SID=....;;

How to install two oracle database on one system

i want to install two oracle databases on single system how it is possible
how i can manager oracle home and is this possible to install two different version of oracle in single home or single system forexample oracle 9 and oracle 8 .
A.R

Hi,
yes, u can have more databases on a single machine and they can be of different versions.
You have to use and initialize the correct ORACLE_HOME to create the DB of the version U use.
For ex, u have 2 homes:
C:\Oracle\Ora817 8i home and C:\Oracle\ora920 9i home
Normally, using OFA, imagine that You want create 2 db, TEST_8I for 8i home and TEST_9I for the 9i home, You shold have:
C:\Oracle\Admin\TEST_8I\<<OFA DIRS>> and C:\Oracle\Oradata\TEST_8I for 8i DB adn C:\Oracle\Admin\TEST_9I\<<OFA DIRS>> and C:\Oracle\Oradata\TEST_9I for the 9i version.
It is important, when You create the DB, that u use the executables of C:\Oracle\Ora817\bin to create 8i db and C:\Oracle\Ora920\bin for the 9i one.
Then U can use the 9i listener to manage both instances
Hope this helps
Max
