One Database on the Machine

Hi all,
I have a database on one machine can i run two databases on the same machine.
Thanx in Advance

Why do you want to run two databases on one machine?
There are good reasons to do so, e.g. maintaining separate environments for the same application (development, integration). There are also bad reasons for doing so, e.g. two different production applications. In most cases I think in the latter situation you are better off putting both apps in separate schemas in the one database.
Cheers, APC

Follwing query fails on one database, but the same works on other Database

Hi,
The following SQL fails on one database with ORA-01722 but the same works on other database.
SQL> SELECT i.version, d.name, i.instance_name, i.host_name
FROM v$instance i, v$database d, v$parameter p 2
3 WHERE p.name = 'instance_number'
4 AND DECODE(p.value, 0, 1, p.value) = i.instance_number;
AND DECODE(p.value, 0, 1, p.value) = i.instance_number
ERROR at line 4:
ORA-01722: invalid number
both databases are at same version (10.2.0.1) both are on same machine.
Initailly I suspected NLS settings, I am surprised to see NLS settings are also same on both the databases.
Any thoughts why is it happening

Thanks for the reply
Yes, i know that i am comparing varchar against number.
bu there is no way that the database where the query is working has correct types on both sides as the tables are standard oracle dictionary tables.
Yes, i tried this earlier, it works
AND DECODE(p.value, '0', '1', p.value) = to_char(i.instance_number)
it is very weired to see that error, i feel it something else that causing the trouble.

Can we start more than one user created database at the same time

Hi.,
Can we start/work more than one user created database at the same time ??
--Shyam

Hi Shyam,
I really dont understand what you have asked?
If your question is can we start more than one database at the same time then the answer to that is yes but provided to have enough resources on your server to support running of two or more different databases on the same machine.

One database with multiple instance names

Dear all,
We would be very happy if anyone can provide me with some information of how RMAN operates.
Current situation: we have 2 machines running Oracle9i with just one database. The production database is "replicated" using EMC's TimeFinder/Snap. The differences are:
1. production database directory structure is slightly different than the replicated one: /usr/oraprod and /usr/orasnap respectively.
2. their pfiles are different: besides the differences in files location (controlfile, dumps,...), the instance_name are different (oraprod and orasnap respectively), but their db_name must be equal, which is oraprod.
3. at startup of the orasnap instance, all datafiles and redolog files must be adjusted/renamed to the orasnap directory structure (using a number of: alter database rename file) and the temporary tablespace needs to be recreated.
The orasnap instance is now ready for use... but problems arises within the RMAN repository. The oracat DB is the rman catalog. Connection to rman is done in this way:
$ORACLE_HOME/bin/rman target "sys/<password>@oraprod" CATALOG "catuser/<password>@oracat"
But "report schema;", whether the target is oraprod or orasnap, lists files which has the orasnap directory structure.
If the target is oraprod, then I expect to see the directory structure of oraprod and NOT the that of orasnap.
Did I overlooked something in here?
All help would be appreciated...
ps: see also my previous thread: "RMAN stops registering backups"

Hi Ebrian,
Another funny thing of RMAN's incarnations: rman seems not to be able to give a detailed backup listing (or restore some files) of the incarnation datafiles like:

Multiple Database behind the Weblogic cluster

          Hi,
          We are working on an enterprise-level EJB based application. Because the scalability and fail-over requirement of the application, we have to at least have 2 database in the backend. Ideally, the 2 database should like one for the Weblogic servers in the app server cluster that are accessing them. There are severl possible solutions:
          1. Have one database as the master data source and another database as stand-by. When the master dabase fails, we could use the Oracle hot-failover to failover to the standby database (am I right? ). The bad thing about this solution is that we are wasting a big box doing nothing, just as standby.
          2. Use a database cluster. I saw some of the discussion in the newsgroup. Basically, the database(s) in the cluster will look like one logical database for the app server cluster. Does anyone have any comments on this solution? Please provide details.
          3. We come up a solution which requires partition of the application into several logical funtion groups and partition the data as well. Even though the solution works technically, it will create a management nightmare for the server cluster.
          Anyone has experience with this? Please comment. Thanks a lot!
          Adam


          Weblogic 7 has a new concept called network channel, where there is a section talking
          about clustering over multiple NIC cards. I was confused by the cluster address in
          customized network channel (no example there). I tried to use multiple NIC cards
          for the purpose of network failover, but failed in clustering environment, although
          I succeed in single server environment.

How to copy a PLD in one database to another.

Hi,
How can we copy a PLD in one database to the other without using Copy Express.
I tried openin up the PLD in the Test DB and copying it over to the Live DB, using Edit copy and Paste, but it doesn't work....
Is there any other way it can be done?
Regards,
Jyoti

hi,
you can copy print layout design using add-on Copy Express available with in SAP B1 add-on package.
or using the sql statement in SQL Server directly
QUERY FOR Copying PLD From one DB to another DB
INSERT INTO [TARGET].[DBO].[RDOC]
SELECT [SOURCE].[DBO].[RDOC].* FROM [SOURCE].[DBO].[RDOC]
WHERE [SOURCE].[DBO].[RDOC].DOCCODE = 'CHO*****'
INSERT INTO [TARGET].[DBO].[RITM]
SELECT [SOURCE].[DBO].[RITM].*
FROM [SOURCE].[DBO].[RITM]
WHERE [SOURCE].[DBO].[RITM].DOCCODE = 'CHO*****' AND [SOURCE].[DBO].[RITM].DOCCODE
IN (SELECT DOCCODE FROM [TARGET].[DBO].[RDOC])
Replace the TARGET field by Target DB name and SOURCE field by Base DB name
DOCCODE is taken from Target DBu2019s PLDu2019s Document Properties.
SELECT DOCCODE FROM [SBODemo_India].[DBO].[RDOC] where docname = 'NEW_AP'
If you know SQL Queries...it is very easy to transfer PLD from one DB to DB by using the above query
or else if you donot kow sql then you can go for Copy express add-on, it is very much simple using that.
hope this will solve your problem

Synchronising 2 Palm devices with 2 different Outlook database on the same PC

Hi,
My wife and I are both equiped with Palms (T5 and T3).
On the familly PC (W7 64 bits) we would like to sync each Palm on a different Outlook (2003) datafile already existing. There only one Outlook profile existing but depending on the email accounts, emails are directed to one database or the otherone.
Once installed the aceeca usb driver (64b..), there was no pb to sync with Palm Desktop.
But I wanted to switch to sync with Outlook, beginning by calendars, there only one calendar available.
As I dont want to mess up the 2 calendard I cancelled the sync.
What is the trick to have separated syncs with the existing 2 different Outlool database files?
Many thanks
Post relates to: Tungsten T5

Your contacts are not part of your iTunes library. iTunes only syncs contacts with your phone from a supported program such as Outlook or mac Address Book. If you are trying to sync you contacts to the same program they will be merged. You could, however, set up two contact groups within Outlook, one for your contacts and one for his. Both groups would still besynced to both devices but you wouldn't have to look at the contact group you weren't interested in. Another option would be for one of you to continue to sync with iTunes with, for example, Outlook and the other sync contacts with another service such as Google or iCloud (be sure to uncheck Sync Contacts on the Info tab of the the iTunes sync settings for this phone).

One Database for All Peoplesoft Applications

Hi,
Does anyone know whether its possible/recommended to use the same database for the different peoplesoft pillars. For example if there are the following apps being deployed:
1. Campus
2. Portal
3. HCM/Payroll
4. FSCM
As I understand it each pillar has its own database - it is possible to share the same database for all pillars - resulting in just one database?
Or is there a combination of pillars that could possibly be used to share the same database?
Thanks

Thanks Nicolas - I was looking at this from the point of view of Oracle E Business Suite which uses just the one database for the entire suite of applications. The question raised here was more from an administrative perspective i.e managing multiple databases - dedicating hardware for each install of the application, or using virtualization to isolate each application. Since I don't have a background in peoplesoft, the way you've explained it appears to at least help in understanding why this is not a good idea on the peoplesoft front - which is what I was looking for.

How to configure EM Grid Control for more than one databases?

Hi,
I'm configuring EM on Oracle 10gRel1 on Linux. I have more than one databases in the server, and I want use IE at my PC to monitor the databases on Linux server. I can configure and access the Grid Control Console by emca for first database, but cannot configure for the second one, unless I remove the first one configurration. How can I configure EM for more than one databases?
Thanks.

Thank you everybody.
Yes, I'm talking about DBConsole rather than Grid Control (sorry for misuse the term). I managed to set up DB Console for every DB in the same Linux box (10Rel1). What I did is:
1) stop db console and agent with emctl
2) remove repository with RepManager
3) config with emca
Then I can monitor individual databases from my PC (but have to login with different port).
I'm thinking mybe I should use Grid Control instead.

COPY DATABASE ON THE SAME UNIX MACHINE

제품 : ORACLE SERVER
작성날짜 : 1997-10-10
INTRODUCTION
The following article deals with creating a copy of a database on the same
unix machine. A database might need to be copied in order to duplicate the
production system, for example for testing purposes. It is recommended that
the reader refer also to the following documentation:
-Oracle 7 Server Administrators Guide
Performing full backups: Chapter 18 page 18-7
OVERVIEW OF PROCEDURE
Before copying the database to a new location, it is necessary to perform
a full cold backup of the database, whilst the database is shutdown. This
will ensure that no data will be lost if the copying of the database is
unsuccessful.
WARNING
Creating a copy of a database involves usage of the CREATE CONTROLFILE command
(explained below). If this command is not executed correctly it could corrupt
the production database. If this happens, and if the files in question are
important, this will mean that the original database will need to be restored
from a backup.
Note: If you are using Oracle 7.1.6 on Sun Solaris 2.X there is a serious
bug with CREATE CONTROLFILE. Call Oracle Worldwide Support asking for
details of <Bug:274054> before proceeding.
1. OBTAIN DATABASE INFORMATION FROM CONTROLFILE
In order to move the database, it is necessary to create a script containing
information about the files of the database.
This is done by executing the following commands.
a. SQLDBA
b. CONNECT INTERNAL, STARTUP MOUNT
c. ALTER DATABASE BACKUP CONTROLFILE TO TRACE RESETLOGS;
This will create a trace file in the trace file directory. The file
will have the extension .trc, and is located either in the directory
defined by the initialization parameter 'user_dump_dest', or, if
this is not defined, in ORACLE_HOME/rdbms/log. The file should be
copied to a name such as ccf<NEW_SID>.sql, where <NEW_SID> is to be
the ORACLE_SID of the copied database.
2. IDENTIFY FILES TO BACKUP/COPY
a. Identify database and log files
The CREATE CONTROLFILE command in the file ccf<NEW_SID>.sql can then be
used to identify the various database files and redo log files that need
to be backed up. The file names will be in single quotes and separated
by commas after the words LOGFILE and DATAFILE, e.g:
CREATE CONTROLFILE REUSE DATABASE "FRITZ" RESETLOGS ARCHIVELOG
MAXLOGFILES 6
MAXLOGMEMBERS 2
MAXDATAFILES 10
MAXINSTANCES 1
MAXLOGHISTORY 100
LOGFILE
GROUP 1 (
'/oracle/tberryha/fritz/log_disk1/fritzlog1v713.dbf',
'/oracle/tberryha/fritz/log_disk2/fritzlog1v713.dbf'
) SIZE 50K,
GROUP 2 (
'/oracle/tberryha/fritz/log_disk1/fritzlog2v713.dbf',
'/oracle/tberryha/fritz/log_disk2/fritzlog2v713.dbf'
) SIZE 50K
DATAFILE
'/oracle/tberryha/fritz/fritz_system/fritz_system01.dbf' SIZE 8M,
'/oracle/tberryha/fritz/fritz_data/fritz_data01.dbf' SIZE 20M,
'/oracle/tberryha/fritz/fritz_rollback/fritz_rollback01.dbf' SIZE 20M,
'/oracle/tberryha/fritz/fritz_temp/fritz_temp01.dbf' SIZE 20M,
'/oracle/tberryha/fritz/fritz_data/fritz_data02.dbf' SIZE 5M,
'/oracle/d2/V7141/dbs/x' SIZE 1M
It is also possible to obtain a listing of the files of the database
by executing the following sql commands:
SQLPLUS username/password
Note: The user must have sufficient privileges to be able to see
the dba views 'sys.dba_data_files', 'sys.v$logfile' and in addition
the database must be open.
SPOOL files.log
SELECT file_name FROM sys.dba_data_files ORDER BY tablespace_name;
SELECT member FROM sys.v$logfile
SPOOL OFF
Note: This will create a spool file called 'files.log' which
will record the results of the previous commands.
b. Identify controlfiles
This can be done either by referring to the init<SID>.ora
'control_files' parameter, or from 7.0.16 onwards, the table
sys.v$controlfile can be used to identify the controlfiles of the
database via the following statement:
SPOOL control.log
SELECT name FROM v$controlfile;
SPOOL OFF
This will create a file called control.log in the current directory
which will contain the names of the controlfiles for the database.
3. BACKUP EXISTING DATABASE
Shutdown instance via SQLDBA, SHUTDOWN NORMAL, and then take full cold
backup of:
a. All the files identified in step 2 above.
b. All parameter files.
Note: the main parameter file will usually be called init<SID>.ora, in
addition to which there may also be other parameter files. These will
be identified by 'ifile' (included file) parameters in the init<SID>.ora.
These additional parameter files are usually called config<SID>.ora.
4. MAKE A COPY OF THE DATABASE
Copy all parameter files, controlfiles, and all files noted in step 1 above
to their new location taking care to preserve ownership and permissions.
When the database has been copied, it will not be possible to use the same
SID and therefore the ORACLE_SID environment variable must
be changed to a new SID, and the copied init<SID>.ora must be
renamed to init<NEW_SID>.ora, and any parameter files pointed to by an
'ifile' parameter (e.g. parameter files such as config<SID>.ora) should be
renamed to incorporate the NEW_SID (i.e. config<NEW_SID>.ora).
5. SET UP PARAMETER FILES FOR THE COPIED DATABASE
Edit the value of the control_files parameter in the init<NEW_SID>.ora to be
the name and location that you want to use for the new control files.
The controlfiles should be given a different name to distinguish them from
the old database. In addition, change the DB_NAME parameter in the
init<NEW_SID>.ora to be an appropriate name for the new database. Any
'ifile' parameters of the parameter file will need to be edited to point to
the new name of the include file in the new location.
6. PREPARE THE 'CREATE CONTROLFILE COMMAND' FOR THE COPIED DATABASE
In order to establish the new database in the new location, the CREATE
CONTROLFILE command in the file ccf<NEW_SID>.sql should be executed. The
following steps illustrate how CREATE CONTROLFILE command is prepared.
a. The file ccf<NEW_SID>.sql must be edited before use. The CREATE
CONTROLFILE command will be preceded by a series of comments and a
STARTUP NOMOUNT command. These need to be stripped out of the file. In
addition, after the create controlfile command, there will be a number
of comments and the commands RECOVER DATABASE and ALTER DATABASE OPEN,
which should also be stripped out, leaving just the create controlfile
command itself.
b. The CREATE CONTROLFILE command itself should also be edited. Change
the CREATE CONTROLFILE command in 'ccf<NEW_SID>.sql' to have the new
database name, and add the word 'SET', e.g:
CREATE CONTROLFILE REUSE DATABASE "olddbname" RESETLOGS
becomes
CREATE CONTROLFILE REUSE set DATABASE "newdbname" RESETLOGS
c. The CREATE CONTROLFILE command also specifies the files which make up
the database, and these must also be changed to name the files of the
new database in the new location, e.g:
LOGFILE
GROUP 1 (
'/old_path/old_logfile_name1',
'/old_path/old_logfile_name2'
) SIZE 50k
would become:
LOGFILE
GROUP 1 (
'/new_path/new_logfile_name1',
'/new_path/new_logfile_name2'
) SIZE 50k
and
DATAFILE
'/old_path/old_file_name1' SIZE 5M,
'/old_path/old_file_name2' SIZE 10M
would become:
DATAFILE
'/new_path/new_file_name1' SIZE 5M,
'/new_path/new_file_name2' SIZE 10M
7. EXECUTE THE 'CREATE CONTROLFILE' COMMAND FOR THE COPIED DATABASE
Having prepared the create controlfile script, it is now necessary to run
the script from within the new instance. This is done by executing the
following:
a. at the operating system prompt, change the value of the environment
variable ORACLE_SID from OLD_SID to NEW_SID. This can be done by using
the following unix command from within the C shell:
%setenv ORACLE_SID NEW_SID
b. SQLDBA
c. CONNECT INTERNAL, STARTUP NOMOUNT PFILE=/<full path>/init<NEW_SID>.ora
d. @ccf<NEW_SID>
Note: if any files which should be specified in the CREATE CONTROLFILE
command are omitted, these files cannot be added to the new database
at a later date. In addition, if any of the files specified in the
CREATE CONTROLFILE command are NOT changed from their original names,
then the corresponding files of the original database will become part
of the copied database, and it will not be possible to restore them to
the original database. If this happens, and if the files in question
are important, this will mean that the original database will need to
be restored from a backup.
e. ALTER DATABASE OPEN RESETLOGS
8. MAKE A FULL COLD BACKUP OF THE COPIED DATABASE
SHUTDOWN and take a full cold backup of the database in the new location.
The full cold backup can be done as detailed in steps 2 and 3.

In fact, you don't even need 2 installs. If you do a server installation

Tuxedo onto your UNIX machine, and build all the clients with the buildlcient

contact Tuxedo.

Create a new database on machine which already has one database running?

Hi,
How can I create a new database on machine which already has one database running on Windows platform?
I am totally new to DB and this is the first time I am creating a database.
When I installed Oracle on windows platform database MYDB got created.
Now I want to create another database with the following command on the same machine.
CREATE DATABASE TESTDB
     DATAFILE 'F:\oracle\oradata\testdb\system01.dbf' SIZE 250M REUSE
     CHARACTER SET US7ASCII
LOGFILE
     GROUP 1 ('F:\oracle\oradata\testdb\redo01.log') SIZE 10M,
     GROUP 2 ('F:\oracle\oradata\testdb\redo02.log') SIZE 10M;
But it doesn't work. I unmounted the DB MYDB and then again tried above command. But still didnt work.
How can I create a new database on machine which already has one database running on Windows platform?
Any sort of guidance is appreciated. Thanx in advance.
latin.

Use DBCA.its a GUI tool for creating the database.

Startup issue when having more than one database on machine

Startup issue when having more than one database on machine:
I’ve installed two databases.
When I shutdown one of the database and try to start it up using
Startup pfile=’…location..’;
I get ora-12514: TNS: listener does not currently know of service rquirest in connect descriptor
when I try it again after 3 seconds, I get a new error, ora-01041: internal error. Hostdef extension doesn’t exist
Shutdown and Startup gave no problems when I had one database. Why am I getting problems when I have two databases?
I’m using: show parameter pfile|spfile; to make sure I have the right parameter locations, so the error shouldn’t be from location.
I’ve never installed two databases on one machine, so maybe I’m making a first-timer’s error.
Anyone know how to get this working, i.e. starting and stopping DB without issues?
Using oracle 11gR2 on Windows 7 64bit, all is working normal.

shows me the name of my first database.
Still not working though.
When I start the services of both databases using Services, I can connect and run queries from both of the database.
Edited by: aymanzone on Jun 15, 2011 11:47 AMFirstly ... the Oracle Service for the instance should be started for the DB you are trying to connect or start.
Next ... from the command prompt:
set oracle_sid=<Instance_Name>
sqlplus sys as sysdba
startup pfile='location of the respective db pfile'
Now, if you want to start or connect to another DB which is on the same server (again assuming the Service is STARTED) ...
From the same command prompt session or other ....
set oracle_sid=<Other_Instance_Name>
sqlplus sys as sysdba
startup pfile='location of the respective db pfile'

How to install Runtime Platform for more than one database on one machine

Hi,
What the docs loosely call Runtime Platform Service is in my opinion a combination of
A) a bunch of software (installed under an ORACLE_HOME)
B) the actual service process
My question: if I have more than one databases on one machine, each containing an OWB Runtime, am I correct in assuming that I have to install the Runtime Platform software only once, but there will be a separate service process running for each database, each adressing the same Runtime Platform software? So under ORACLE_HOME nothing is kept that refers to a particular database?
Jaap.

Yes, we use such a configuration on our site. We have one OWB ORACLE_HOME and uses up to 4 instances. Each instance has its own Runtime Service Process running.

Two machines using syncing to one database.

We're in development/eval for 7.0 Portal right now, and every time we sync to another
machine the other machine(s) stop working and get "Null Portal Object" webflow
exception. Is there a way to have multiple people hitting one database? We're
thinking of letting each developer have her/his own BEA instance on her/his machine.

Steve,
There are two ways to solve the problem of which one I know is described in
the developers guide:
1. Each developer should have his own enterprise application (e.g.
developer1_app, developer2_app). The synchronization works by the
enterprise id and I believe it's immediately propogated to the in-memory
repository even when the developer is on another workstation. Separating
the namespace by enterprise application name will solve that.
2. Create separate database instances. This is the approach we took and
it works fine. Everybody datasyncs in private now against the same
<application-project> directory stored in our CMS.
Hope that helps,
Wayne
