Database copy on same server

Hi guys,
I want to copy the existing 6.40 system TBW to a new instance TBX on the same server. I've created all filesystems, copied the content, changed SIDs and paths in environment scripts and profiles and restored the database TBW to TBX with brdb6brt. Now my problem is to understand how to set the permissions and users correctly. the authorizations are stored in the DBM(SYSADM,SYSCTRL and SYSMAINT group) and their names contain the SID of the instance. So what do I do? Copy the db2tbw user to db2tbx and assign the "wrong" old groups to it? Or use the same user db2tbw also for db2tbx? Or is it possible to have more than one DBM per server? What are the best practices about more than one SAP DB/2 instance on one server? Any docus around?
Regards,
Pascal

Hi Pascal
use everything separate
[except Database Connect Users since Database schemata cannot be renamed .]
There is nothing special when performing a systemcopy on the same server .
Hint : The group names need to be adjusted in the DBM config
>>>snip<<<
Copy the db2tbw user to db2tbx and assign the "wrong" old groups to it?
>>>snip<<<
No , better
create an new user db2tbx
create the according groups
dbtbxadm , dbtbxctl , dbtbxmnt and assign db2tbx to these groups
create an new database instance db2tbx and restore your
database into this instance
>>>snip<<<
Or use the same user db2tbw also for db2tbx?
>>>snip<<<
This is not possible , you need an new separate database instance "db2<dbsid>" for your new Database TBX .
>>>snip<<<
Or is it possible to have more than one DBM per server?
>>>snip<<<
Yes of course you can have more than one database instance per server .

Restore database in the same server but with other sid (name)

i try to restore the database in the same server but with other sid (name) . The backup is on tape and
I want to know the steps I should follow.
thank.

To perform restore of database in same host to choose another DB name you can go for
1) duplicate using RMAN.
Directory structure should be different so take care of db_file_name_convert & log_file_name_convert parameters
Also check the Tns services exactly is it pointing to target & auxiliary

Installation of EBS 12.1 and Database on the same server

Hi,
Due to resource crunch, I would like to do new installation of EBS 12.1 and Database on the same server where already EBS 12.1 and Database installed.
I have one server where EBS 12.1 and Database installed (Single node installation).
Now I want to create another environment for other purpose (another test env.). But I don't have another server .
So Can I start new installation of EBS 12.1 and database on the same server ?
I have enough space and memory on server.
Are the installtion conflict with each other ? any implications happen on the first environment ?
I want my first environment run fine without any prob., after installing EBS and DB on the same server.
Please guide me.

Sanjay Patel

Are the installtion conflict with each other ? any implications happen on the first environment ? If you install in different ORACLE_HOMEs you should be OK.

Install two 10gAS infrastructure databases in a same server

Can I install two 10AS infrastructure database in a same server? Each database will be used for different purposes.

Never tried that but I belive that you can.
It is the same as two classic databases on same machine.

Rman duplication of database to the same server and same disk group

Hi,
We have multiple databases - rmsprd1 and oidprd1 on asm disk groups - ASMDG_DAT01 and ASMDG_FRA01 on a server.
Both these databases are single instance asm based databases.
I am trying to do a rman duplication from rmsprd1 to rmsprd2 in the same server. I intend to use the same asm disk groups - ASMDG_DAT01 and ASMDG_FRA01.
Is this possible ?
Currently I have the following structure
+ASMDG_DAT01/RMSPRD1/DATAFILE
+ASMDG_DAT01/RMSPRD1/CHANGETRACKING/
+ASMDG_DAT01/RMSPRD1/CONTROLFILE/
+ASMDG_DAT01/RMSPRD1/DATAFILE/
+ASMDG_DAT01/RMSPRD1/ONLINELOG/
+ASMDG_DAT01/RMSPRD1/PARAMETERFILE/
+ASMDG_DAT01/RMSPRD1/TEMPFILE/
+ASMDG_FRA01/RMSPRD1/AUTOBACKUP/
+ASMDG_FRA01/RMSPRD1/BACKUPSET/
+ASMDG_FRA01/RMSPRD1/CONTROLFILE/
+ASMDG_FRA01/RMSPRD1/DATAFILE/
+ASMDG_FRA01/RMSPRD1/ONLINELOG/
Will I be able to create something like
+ASMDG_DAT01/RMSPRD2/DATAFILE
+ASMDG_DAT01/RMSPRD2/CHANGETRACKING/
+ASMDG_DAT01/RMSPRD2/CONTROLFILE/
+ASMDG_DAT01/RMSPRD2/DATAFILE/
+ASMDG_DAT01/RMSPRD2/ONLINELOG/
+ASMDG_DAT01/RMSPRD2/PARAMETERFILE/
+ASMDG_DAT01/RMSPRD2/TEMPFILE/
+ASMDG_FRA01/RMSPRD2/AUTOBACKUP/
+ASMDG_FRA01/RMSPRD2/BACKUPSET/
+ASMDG_FRA01/RMSPRD2/CONTROLFILE/
+ASMDG_FRA01/RMSPRD2/DATAFILE/
+ASMDG_FRA01/RMSPRD2/ONLINELOG/
I know that I can create a different asm disk group for the rman duplication but this is proving to be a hassle.
Thanks

Hi,
I have found the answer working with Oracle via a service request. Admittedly there was no direct oracle documentation for doing this and hence documenting the steps here.
No legalities, formalities involved please.
Here are the steps - rmsprd1 is the source, rmsprd2 is the target, +ASM is the asm instance supporting both rmsprd1 and rmsprd2. The intention is to put both the source and destination in the same server. The backupset backup in location /dbaadm/sandeep_rman_refresh will be used for the duplication.
1) Take rman backupset backup of the source database - rmsprd1
rman_take_backup.ksh ( Take backup of source - rmsprd1 using rman ). The contents of the rman_take_backup.sh script are given below :
rm /dbaadm/sandeep_rman_refresh/*
export NLS_DATE_FORMAT='YYYY-MM-DD:HH24:MI:SS'
rman target / <<EOF
run
allocate channel d1 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d2 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d3 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d4 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d5 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d6 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dbaadm/sandeep_rman_refresh/%F';
backup as backupset database plus archivelog tag 'clonebackupset';
EOF
2) Make the directories for destination database ( rmsprd2 )
/opt/oracle/admin> mkdir -p rmsprd2/adump rmsprd2/dpdump rmsprd2/pfile rmsprd2/scripts
3) Create pfile from rmsprd1 spfile. copy/rename the pfile to make a pfile for rmsprd2.
4) Edit listener.ora in ASM ORACLE_HOME and edit tnsnames.ora in DB ORACLE_HOME
listener.ora
LISTENER_RMSPRD2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = kirkjerpdb01.kirklands.com)(PORT = 1522))

( SID_NAME = rmsprd2 )
ADR_BASE_LISTENER_RMSPRD2 = /opt/oracle
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_RMSPRD2=ON # Section added by Sandeep

(ADDRESS = (PROTOCOL = TCP)(HOST = kirkjerpdb01.kirklands.com)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rmsprd2)
(UR = A)
5) Build a passwordfile ( I just copied and renamed it )
6) Edit /etc/oratab to add database entry for rmsprd2
7) Set the environment for rmsprd2
. oraenv
rmsprd2
8) Startup nomount of rmsprd2
sqlplus / as sysdba
startup nomount pfile=/opt/oracle/admin/rmsprd2/pfile/initrmsprd2.ora
9) Create spfile from pfile='/opt/oracle/admin/rmsprd2/pfile/initrmsprd2.ora';
10) shutdown and startup rmsprd2 with spfile
SQL> shutdown abort;
ORACLE instance shut down.
SQL> startup nomount;
ORACLE instance started.
Total System Global Area 1068937216 bytes
Fixed Size 2213632 bytes
Variable Size 788531456 bytes
Database Buffers 268435456 bytes
Redo Buffers 9756672 bytes
11) We are now ready for duplication from rmsprd1 ( source ) to rmsprd2 ( destination ) both using +ASM standalone asm instance. set the environment to rmsprd1and fire away.
Please note that the duplicate script is only connecting to auxilary database ( rmsprd2 ) and using the backup location for the duplication.
I used a unix shell script -rman_duplicate_from_backup.ksh. The contents are given below :
$ORACLE_HOME/bin/rman auxiliary sys/prd123@rmsprd2 log=rman_duplicate_from_backup.log << EOF
run
allocate auxiliary channel d1 device type disk;
allocate auxiliary channel d2 device type disk;
allocate auxiliary channel d3 device type disk;
allocate auxiliary channel d4 device type disk;
allocate auxiliary channel d5 device type disk;
allocate auxiliary channel d6 device type disk;
DUPLICATE DATABASE TO rmsprd2
BACKUP LOCATION '/dbaadm/sandeep_rman_refresh';
EOF
12) Voila - the rmsprd1 to rmsprd2 is done.....
Hope this helps somebody else wanting to do the same excercize. Have Fun.....

Application and Database on the same server

I have a Java Application and a db2 database(SWDTEST) that reside on the same server. In the Application I want to connect to the database. What would I use to do this? When the application resides on a client machine I use the "sun.jdbc.odbc.JdbcOdbcDriver" driver and can get a connection. Code looks like:
try{
//load the driver class
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//Define the data source for the driver
String wdURL = "jdbc:odbc:SWDTEST";
String username = "UNTEST";
String password = "PTEST";
wdConnection = DriverManager.getConnection(wdURL, username, password);
wdStatement = wdConnection.createStatement();
catch(SQLException e)
System.out.println( e.toString() );
But when I move the same application to the server and run it I get the following error message:
java.sql.SQLException: [IBM][CLI Driver] SQL1013N The database alias name or database name "SWDTEST" could not be found. SQLSTATE=42705
Do I need to set something on the server so that SWDTEST is a recognized database name or connect to it some other way?
Thanks in advance.

Does the server have ODBC installed on it? (Windows boxes will, unix will likely not.)
Do you have a ODBC driver installed on the the server. This has nothing to do with java.
Have you created a DSN on the server?

Moving the database in the same server

Your replay:-
for WIN NT: take a look at note 61747.1 Moving a 7.3 or 8.x database. And take a look at Note:99275.1, UNIX/NT: Moving a Database Within the Same Machine.
Clarification: Where can i get the help for Note:61747.1 & 99275.1

Sorry Sridhar.
Take a look in MetaLink (www.metalink.com) and use the note ids to look up the information.
Thanks.

How to configure one Listener for 2 databases on the same server

Hello all,
Please, I am stuck as with my application server which requests the port 1521. I want to configure the repository to make use of the port 1521 which is also shared by another database on the server.

Create dev and test instances of Apex on the same server and database

I have a dev and prod instances of Apex on different servers. I want a test instance on the same server as the dev instance.
I am using workspace export/import so all instance workspaces have the same workspace id. The application ID is the same on each instance, in the same workspace. This allows pages to be exported/imported in the differenct instances.
My question is (I am sure it is obvious) can I have more than one instances of Apex on the same database (dev and test) and have each instance have identical Workspace IDs, etc.
Sam

Hi Sam,
But you can have more than one database on the same server.
What we do is create a separate database for each APEX versions we are supporting (we still have a customer using APEX 2.0).
All the databases are accessed with the same APACHE config. All you have to do is change the DAD and have a separate dad for each database (i.e. each APEX versions).
ex : /pls/apex_dev /pls/apex_test
This way , I can run different APEX versions on the same server.

Insert into different database - same server

What do I need to do to insert values into a table in a database on the same server?
I have databases A and B. I have a procedure in Database B that needs to insert a record into a table in Database A. I tried qualifying:
Insert into DataBaseA.SchemaA.tableA (fields..) Values (values...); but that didn't work. I saw something on creating a link but I didn't quite understand it and all of the posts I have read haven't really given a clear syntax usage.
Can anyone help? I also don't know the table to insert into until the procedure is run so I can't create anything "static".
Thanks,
Greg

Hi Greg,
You have to create a database link. Go through the following link for details:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_56a.htm#SQLRF01205
Please let me know if you still have any concern.

How to create linked server to multiple database on same server?

Hi Experts
I want to create linked server to multiple databases on the same server.
I have 2 database servers (ServerA and ServerB) and want to create linked server on ServerB to link multiple databases on ServerA).
I have admin right on ServerB.
I don't have admin right on ServerA but have different accounts to access on each databases on ServerA.
After I created one linked server object to a database, I cannot create another linked server object for another database as it has already used the server name which is ServerA.
Please advise.
Thanks.

EXEC sp_addlinkedserver 'ServerADB1', '', 'SQLNCLI', 'ServerA', @catalog = 'DB1'
EXEC sp_addlinkedserver 'ServerADB2', '', 'SQLNCLI', 'ServerA', @catalog = 'DB2'
etc.
Please look up the details for sp_addlinkedserver as I typed this from memory.
I can certainly see a point in having one linked server per database, as then you don't have to hardcode the database name in the queries, and the linked-server definitions can be changed if the database name changes.

2 Portal Instances on Same Server

I am trying to create a second portal instance in a separate database on the same server. The 9iAS lives on another server. I have already successfully got the first portal up and running with web browser access. However, I'm not sure how to get the second portal up and running with that ssodatan script.
I tried specifying a separate port (7778) in that script and started a second port listening in httpd.conf, but this doesn't work. I also tried specifying a separate port and separate url (like portal302 and portal302_sso) in the http parts of that script, but this didn't work either.
Each portal has it's own login server installed, so I don't want to associate both portals with a single login server.
Can someone help me??? Thanks.

Kathryn,
Presumably you installed both Portal instances in different schemas (i.e. Portal30 and Portal309 etc.). If so, then all you will have to do is run the ssodatan script against each, referencing the exact http address for each. Once you have done this you should be able to contact both from the same http port (i.e. port 80) by referencing them in the URL (i.e. http://www.foo.com/pls/portal30 and http://www.foo.com/pls/portal309.

About listeners for different databases in the same ORACLE_HOME

Hello experts, I have a doubt
I have installed 3 different databases in the same server which OS is Suse Enterprise 10. At this moment I have just one listener that registers all the services. The number of connections are big for two of the three databases so I do not know what might be the best practices for this environment. I have some question I would like you suggestion for me:
DB version: 11.1.0.7
Should I have three listener, one for each database?
Is a good practice to have only one listener for multiple instances in the same server?
Are there differents between have only one listener for all the instance and have one listener for instance?
What about the performance?
Than you in advance, I hope you can guide me.

Best practice is not to have multiple databases on one server, depending on resources.
Should I have three listener, one for each database?
No. That is pretty undesirable and requires more administration.
Is a good practice to have only one listener for multiple instances in the same server?
Yes. Remember the listener is only a broker and there are no permanent connections between client, listener and database.
Are there differents between have only one listener for all the instance and have one listener for instance?
Yes. The latter is an administration nightmare.
What about the performance?
Who cares? The only factors are
listener.log becomes too big --> set up proper cleanup procedures
The number of semaphores is exceeded (Unix) or no more threads can be created (Microsoft winblows), which will give rise to ora-12500.
