Two oracle on one host

Dear Friends,
I have installed oracle and SAP which is working fine.now i have requirement where i have to install another database with smsaproper and smsaproperadm user database on one host. on second database sap is not installed. It is used for some other purpose ie for disaater recovery. First database is used for SAP and second one is used for non-sap.
Please suggest how to proceed with this.
Thanks in advance.
Regards
Jiggi

With a slight modification ... U donot need two separate listeners to support two databases on the same host.
You can very well have one listener control catering to both the databases.
Here are some tips ....
Say ur sap sid is S1 so u r having two OS id oras1 and s1adm with proper env settings.
For the non sap application say instance name is APP1
so u shud have oraapp1 Operating system user with proper env settings like
ORACLE_HOME= /oracle/APP1/10_2....
LIBPATH/LD_LIBRARY_PATH=$ORACLE_HOME/lib
ORACLE_SID=APP1
The path variable under this user ie(oraapp1) should not have any entry pointing to the ORACLE_HOME of SAP application.
As I said one listener is good enough to cater both the databases you just need to open up the listener file ie listener.ora under $ORACLE_HOME/network/admin (this oracle home can be of ur sap appliaction or ur APP1 home depending upon which listener u wish to make use of )If u wish to have app1 listener catering both app1 and sap DB then add entry for sap DB in the listener.ora of APP1 database or vice versa.
Any problem with this ,do write back.

Installing two systems in one host - clarification

Hi Experts,
We have requirement to install the R3 and BI development system in the same host.
I have completed installation of the BI7 system.
The database used is SQL server 2005.
Now when we install the other system, I am not sure how to go about the database.
Do I need to install again SQL server 2005 in some other drive or the existing one can be used, that means will it add a new database to the existing database server?
Thanks and Regards,
Amit Jana.

Hi,
While installing ECC6 on MSSQL 2005 the instance is not starting up.
In SAPMMC console the dispather is stopping as all the wp s are dying.
I am giving the error log from dev_w0.

More than one Database Server on one host

Hallo,
We want to implement two systems on one host with MaxDb as database. I know it is possible to run 2 DB-Instances on one host, is it possible to upgrade or patch one instance without inflicting the other one with this changes?
For example:
I have the development and test system on one host with two database instances running. is it possible to only upgrade the Database Instance of the Development System without upgrading the test instance.
I know it is possible in Oracle but is this also possible for MaxDB?
I hope you can give me an answer.
best regards,
Patrick Volny

Hello Patrick,
1) "If I understand you correctly, I am able to patch each Instance separately but because the instances share the same kernel to upgrade an Database I have to upgrade all instances?"
    Answer: You can update the database instance separately.
                   As the independent database software is shared between database instances, located in /sapdb/programs by default installation and it's downward compatible
                  ==>
                  you could upgrade only one database instance & run the another database instance with the higher version of the independent database software.
   Warning: Please follow the recommended structure of the database software installation & install the dependent on the version of the database system software once for each database instance.
                  By default it's installed in /sapdb/<SID>/db
    Example : On the local server ::
dbmcli db_enum
OK
SC1#C:\sapdb\sc1\db                        #7.6.04.11#fast#running
SC1#C:\sapdb\sc1\db                        #7.6.04.11#slow#offline
LVC750#c:\sapdb\lvc750\db                     #7.6.00.21#fast#offline
LVC750#c:\sapdb\lvc750\db                     #7.6.00.21#slow#offline
xinstinfo SC1
IndepData           : C:\sapdb\data
IndepPrograms       : C:\sapdb\programs
InstallationPath    : C:\sapdb\sc1\db
Kernelversion       : KERNEL    7.6.04   BUILD 011-123-181-372
Rundirectory        : c:\sapdb\data\wrk\SC1
xinstinfo LVC750
IndepData           : C:\sapdb\data
IndepPrograms       : C:\sapdb\programs
InstallationPath    : c:\sapdb\lvc750\db
Kernelversion       : KERNEL    7.6.00   BUILD 021-123-117-795
Rundirectory        : c:\sapdb\data\wrk\LVC750
In my case, I have installed two database instances of the versions 7.6.00   BUILD 021 and 7.6.04   BUILD 011 on one server,
Independent database software is installed in C:\sapdb\programs and each database instance has own InstallationPath.
And you could run also 'sdbregview -l' to get the short list of all installed database packages, pay attention to the "Database Kernel" package
for the dependent database software installation path/version.
2) "I also read that to patch an instance you have to stop an x server service. But this service is necessary for the communication between applications and the database. so if i patch an instance the second one can't work properly?"
The X Server is needed for the client to establish the connection to a database instance located on a remote computer. As you know the X Server is the communication server for the database system. The X Server listens out for connection requests from clients such as database applications and database tools.
As I already wrote you, that the independent database software is downward compatible & you should not have the problems with the communication to the Test database on the TEST system.
I case you would like to know more details about the database version software, if there are any known problems, please update with additional information::
      What are the current versions of the DEV and Test databases?
      Did you install the application servers on the database server or not?
      To what version of the database are you going to update the DEV database instance?
       What is the version/SP of the SAP basis on the TEST system?
        What is the version/patch of the SAP kernel on the TEST system?
3) The installation distinguishes between different software directories, as you already know.
For example, the following directories:
       - <independent_program_path>
          SAP Standard:/sapdb/programs
          Run the command 'dbmcli -s dbm_getpath IndepProgPath' or 'xinstinfo' to get the current value on your system.
          !!!! This directory contains instance- or version-independent software that works downwardly-compatible.
       - <independent_data_path>
          SAP Standard:/sapdb/data
           Run the command 'dbmcli -s dbm_getpath IndepDataPath' or 'xinstinfo' to get the current value on your system.
       - <independent_data_path>/config
          SAP Standard:/sapdb/data/config
       - <InstallationPath>
SAP standard: /sapdb/<SID>/db
       - <run_directory>
SAP standard: /sapdb/data/wrk/SID
If you are SAP customer,
please see the SAP notes::
             1020175     FAQ: MaxDB installation, upgrade or applying a patch

Two systems on one databses

Hi,
we are currently running our QA and DEV systems one one host and one sql server 2000.the systems version is 4.6c.we are going to upgrade our systems to ecc6.I would like to know if this configuration (two systems on one host and one DB - <u>not mcod!!!!</u>) is supported on ecc6 and on sql server 2005.in notes 28392,171929 it is mentioned only regarding windows 2000 and sql server and sql server 2000.
Regards,
Moshe

Ah - Ok - I got it:)
This configuration is supported since SQL Server 7.0 and I don't find any note or information telling, that it's no more support on 2005, so I would say YES, it is supported.
However, to get a definite answer I'd open an OSS call under BC-DB-MSS and ask the guys from SAP.

Two oracle database

I have created TWO oracle database one is 8i and second is 10.
I want oracle 8i my default oracle database.
I have changed Environment Variable > System Variable > PATH > to 8i bin folder..but again..
C:\Documents and Settings\Administrator>sqlplus
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Oct 15 11:52:12 2010

Dear oracleRaj!
To connect to a specific Oracle database you need to set three Env variables
1.) %PATH%
2.) %ORACLE_SID%
3.) %ORACLE_HOME%
It looks like you only set %PATH% but not %ORACLE_HOME% and %ORACLE_SID%. For your convenience you may write two batchscripts to set these variables. One for 8i and one for 10g like this:
oracle10g.bat
set ORACLE_SID=sid_of_your_oracle_10g_database
set ORACLE_HOME=path_to_your_oracle_10g_homedirectory
set PATH=%PATH%;%ORACLE_HOME%\binYours sincerely

Two SAP system in one host and one oracle software

Hi SAP Gurus,
We want to install Two SAP system (PR1 & PP1) in one host(Prdb05) and one database (Oracle). I dont want to do MCOD.
I am very confuse about what changes i need to make before start the install of PP1. Actually i do not required to install oracle software again. am i correct ?
also i do not required to install oracle client again.am i correct ?
Will it take software automatically ?
In SAP note 350251 they asked me to run ./runinstaller !!! but when we
are not installing software again why we need to to execute that.
Will you please guide us for the same.

Hi , This is what you have to do .
Couple of questions before i answer anything
1) Is your first SAP system installed ?
2) is this High Available system
What Oliver suggested is a valid option on Windows , but not on Unix .
In Unix you might face problems for user,groups because the user for ORACLE_HOME should ideally be ora<SID>, and if you have 2 SID and one ORACLE_HOME , which user will you give ?
So , it is better that you have 2 seperate oracle software installed , 2 seperate ORACLE_HOME , 2 seperate filesystems for oracle software .
Hope you understood , what i am trying to say .
Thanks

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.

Juan

Two database with the same sid but different ORACLE_HOME on one host

two database with the same sid but different
ORACLE_HOME on one host,and if configure them with
two differnt lisnter staticaclly,this abosultely work
because in the lisnter.ora we must provice
ORACLE_HOME variable,with this ORACLE_HOME the client
can differentiate which database to connect,but if
use dynamically register feature,how can the client
tell which database to connect?

Also note that this type of configurtion may not be supported.
Just because a given configuration works in certain given conditions does not mean that it would be supported.
If this setup is for a configuration that has any value, please also Contact Oracle Support to get their inputs on what you are trying to accomplish.

Is it possible to install two SAP system with same SID but different instance numbers on one host?

Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
If yes, then how?
If no, then why?
Thanks in advance.
Regards,
Sarim

Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
Yes, it is possible. If one is CI (PAS) and the second one is an AS (AAS). In this case there will be only one database.
If you are talking about two separate SAP systems with separate databases (Eg: A BI and an ECC) with the same SID then the problem will be with the database (Eg: Oracle)
The database will be installed under /oracle/SID/112_64 (ORACLE_HOME) unless one database is running on 10 G and in that case the ORACLE_HOME will be /oracle/SID/102_64
The next issue will be with the SAP file systems like /sapmnt/SID
The most important problem will be with the switch to the sidadm and orasid users and the conflicts there. If there is a need to stop one of the SAP systems and if you do a switch to sidadm and issue a stopsap command which system will be stopped ?
These are few of the many problems I can think of.
So if we are talking about two separate systems with their own databases I would rule out the possibility of having two systems with the same SID.

Two oracle versions on one client

Hello
I installed Oracle7 and Oracle8 Client together on the same machine.
So far it works well. But when I want to open one of my ODBC Drivers, I4m getting the following error:
ODBCADM caused a general protection fault in KRNL386.exe at 0001:243F.
Is it possible, that this is because of the two Oracle versions?
Or does anybody have another idea?
Thanks, Anja

Hi,
Like Kamal said, no problem. You can have 2 tnsnames.ora, one in 8i (where you declare 8i databases), and one in 10g (where you declare 10g databases).
To connect to 8i, set ORACLE_HOME to 8i directory and use 8i sqlplus.
To connect to 10g, set ORACLE_HOME to 10g directory and use 10g sqlplus.

Transfer data from two oracle version to one sql server 2005

Hi,
I have two database servers on different machines. They are
1) Oracle 8.1.7.4
2) Oracle 7.3.1.4
I have to create agents which can transfer tables from these two databases to one machine having sql server 2005 database.
Please tell me what are the options. What drivers i need to install on machine having sql server 2005 so that i can transfer data from both oracle versions.
Thanks
Rajneesh.

Your Oracle databases are so old you might want to look around and see if you can find dinosaur bones near by.
Given the differences in data types between Oracle and SQL Server I'd suggest you start off by dumping the data into delimited ASCII files and then loading it using whichever SQL Server tool you wish.

Two solamn sap systems in One host ????

Experts,
Is it possible to install two solman 7.0 sap systems in single host.
Aleady i have installed solman 7.0/Ms sql 2005 in the Windows Host. I want to install another solman 7.0 in different SID in same the host for testing purpose.
(I installed ECC and CRM servers in the same host its works fine.)
PLease give your suggesstion
Thanks
Thirumal

Hi thirumal,
we can install two solman in one system through a concept called MCOD ie multiple components in one Database.
just as we can different SID's in one database.
for more information refer this site:

Oracle Reports : one query - two reports?

Help, please, Oracle Reports 10g.
I have a query, need to make two reports in one. They are similar, just couple parameters are different, say, entreprise type and region;
How do I display these two reports in one? I tried to make parameters as placeholders, package variables, put an trigger on outer frames for reports. parameters do change their values but just the same report displays twice. where is the trick?
Thank you

The way I have done this in the past was to create 2 master frames, 1 for each report and then put conditions on each frame as to when it is to appear. Hope this helps..

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

Installing two Oracle Version in One Windows[/b]

Hi Guys
I want to know how to install two different versions of Oracle in One Windows Under Different Homes.

A guess is that this is due to the earlier 8.1.7.x ODBC drivers did not support multiple homes (max one ODBC version per PC - ugh!).
If you can't skip this error, try to uninstall 9i ODBC, install 8i, upgrade 8i driver and then reinstall 9i ODBC (in the right home)... I guess a better way would be to do this in the correct order on a clean PC (to avoid registry messup as much as possible).
