ORACLE SID vs DBID vs INSTANCE_NUMBER

Hey,
Can please anybody explain me the difference between:
1. ORACLE SID
2. ORACLE DBID

3 Instnaces with same Oracle SID, How I do?

Plase look and your concern about follow scenario:
Server A is production, oracle sid = uno
Server B will be a stand by database from Server A, oracle sid = ??? "uno"
Server B will be QA database from Server A, oracle sid = ?? (uno)
- Product 8.1.7 on unix backup box
- I want to have one standby database with one unix user ora8i1 and sid="db1".
- I want to have a QA instance in same box with other unix user ora8i2 and sid="db2".
- Can I have it these?
- What about the listener, Do I need configurate it manually?
My Idea is:
1. Produccion rdbms sid='db1'
2. Backup server with stand by database sid=???
3. To have a QA instance from db1 on the backup server where the analyst can test their programs, before Produccion, sid=????.
4. Point 2 and 3 with Ora8i 8.1.7.1 on same unix hp box.
In the other words, I want to have on same hp unix box two instances from main production instance 'db1'. One instance have a stand by database and other instance have a QA test database, both instances have a dentical copy from 'db1' inicially.
What you suggest me?
Thanks

Get Oracle SID in PL/SQL with out a query

Hi,
Is there any way where I can get ORACLE SID value in the PL/SQL layer with out actually querying v$database tables.
I am looking for key word in PL/SQL which stores currect SID name, just like how keyword 'user' stores the current user who has logged in.
Thanks

/appdev.102/b14261/subprograms.htm#sthref1776]'user'
is a built-in function provided by Oracle. Why don't you create your own function to perform the
Select?
I know I can create a function but, I dont want to read the table everytime it is called. Knowing that Database sid is going to be constant for next couple of years.
The procedure in which I am going to use database sid is called for almost every transaction in the database. I am trying to avoid IO operation for a constant value. I cant declare a global constant as it is going to be different for each environment Dev, QA, Production etc..and we are looking to deploy same code for all the environments. We are anticipating to have multiple databases for production too.

Oracle sid 102isql service not working

Hi,
oracle<sid>102isql is not in start status, when i try to start it i got below message.
the above service could not start local services and error:1067 the process terminated unexpectedly.
iam not able to connect the SAP for this reason.Please advice.
Regards,
Asif

Hi,
Check the DB and Listener is UP or not.. If it OK and still you are facing database connection problem then check the TNS entry in tnsnames.ora file is correcty given or not. The host, port and SID of TNS entry should match with Listener Host, Port and SID.
Check the Listener status using the command
lsnrctl status
Check the TNSping using Command
tnsping <DB TNS entry name>
Then check SAP is able to connect the DB using command
R3trans -d
if it give the return code 0, then SAP will be able to connect DB.
Thanks

DRDA is installed just on the Oracle side?

After reading this I still dont get it...
http://download-east.oracle.com/docs/cd/B19306_01/gateways.102/b16217/intro.htm#i3621
This documentation does not get to the point at all. It is not written at a level for people who have never installed a Transparent Gateway...
So, If I install the DRDA type Transparent Gateway I'm hoping I only have to put software on the Oracle side - my side? Not the DB2 side? I saw via someone else's post where during DRDA setup a package is created on DB2 side by issuing commands on the Oracle side?
If this is true, which I hope it is, why and what benefit is obtained by installing the other type of gateway Transparent Gateway for DB2 (TD4DB2) which requires installation of software on both sides - I think?
I would like to only have to install software on the Oracle side since the DB2 machine is not owned by us and all we will have is a user account on the DB2 side.
Give me few quick pointers please.. Thanks...

The DRDA Gateway software is only installed on the the Oracle server machine (or a 3rd machine).
There are several notes on Metalink "How to setup TG4DRDA" which explain in detail WHAT steps are required to configure the gateway.
Regarding the Bind package: at the Db2 database the 2PC table must be created and then use SQL*Plus to bind a package at the Db2 side.
This is mandatory for the DRDA gateway, but I want to make it clear again: NO software is installed on the DB2 machine.
So the difference between the TG4DB2/400 and TG4DRDA is the location of the software.
TG4DRDA is installed on Unix or Windows platforms, commonly in the Oracle database home whereas TG4DB2/400 is installed on the AS400 machine.

Difference between Oracle SID and an Oracle Database

Hi
Can any one please differeniate what exactly is the difference between an Oracle SID and a new Oracle Database?
We just need to create another instance of an application (so we need another copy of all tables).
So either we can:
1. New database SID created or
2. New user created in existing schema or
3. New database provided
Which is the best approach?

Hi,
New database SID created orThat is equivalent of creating a new database in your case.
New user created in existing schema orYou meant new schema(user) created in existing database. I assumed this because you do not want both application to update the same table copy, but different copy.
3. New database providedIt all depends on your you whether you want to create a new database or a new schema for getting another copy of table.
Some points which I take in mind
1) If I have a production database and I need to create a new set of tables for testing or any other purpose, I would create a new database.
2) If I have a test database and I need to create a new set of tables for testing or any other purpose, if possible I would create a new schema in existing database.
3) If I am running less in resources(hardware/memory), I would be createing a new schema in existing database.
4) If I am not running less in resources and I would to keep these two copies entirely different, then from security purpose I would create a new database.

/oracle/ SID Directory is full

Hi, All
We are using ECC6 on HPUnix with Oracle. in our quality server /oracle/<sid> directory is full. Any one can explain what are the files i have to delete or i have to increase the volume.
Please suggest
Thanks & Regard
Venkat

Hi
Please also check the size of the /oracle/SID/saptrace directory, you can use du:
orasid> du -k /oracle/SID/saptrace
The saptrace directory holds the alert log, user and background traces of the database. Sometimes core files are placed there as well. All those files can be deleted (please do not remove the background and usertrace directories), but if you encounter a lot of traces or cores, you should investigate further and try to fix the problems.
Best regards
Michael

Changing Oracle SID

I have copied a database (all physical files) from one server to another. I now want to change the Oracle SID (from prod to dev) of the copied database - How can I achieve this?
Thanks in advance
Terry

set ORACLE_SID = 'DEV'
or If u r using NT then make this Change in registry so u dont have u use set command all the time.

OID Working Normally But I Want to Understand "oracle SID " Processes

I'm runninng OID as part of an Identity Mangagement 10.1.4.0.1 installation on Linux. When I look at the processes that oracle is running I see many "oracle<SID>" processes.
I'm looking for where I can read about the different types of processes that comprise OID on Unix/Linux. I'm particularly interested in knowing how "oracle<SID>" processes are created and destroyed -- is each process synonymous with an active connection to the directory?
Thank you for pointing me to the docs on this or telling me what you believe these "oracle<SID>" processes represent.

Those Oracle<sid> processes are database instance processes - OID is implemented in a database (where else?).
They should be there for the life time of your server - they should not be killed, destroyed or whatever - they can be stopped by logging into your server - after setting the proper environment variables, execute:
sqlplus / as sysdba
shutdown
exit
The shutdown can take a while - it allows all active, current sessions to do their thing. Another option is shutdown immediate, which will kill active sessions, as soon as the running transaction finishes. Both options result in a clean shutdown, leaving the database in a consistent state.
A real killer is shutdown abort - it will simply abort all transactions, but leaves the database in an inconsistent state. Oracle will recover automatically in most cases.

IP Address Changed in the Oracle SID

Dear Team ,
I have Changed the IP address of the Oracle SID I am using (ORACLE 10g) in Listener.ora and tnsnames.ora file .
While I am starting my application I got this below error.
Io exception: The Network Adapter could not establish the
connection
Is there any procedure to be followed while changing the Ip Address .
Kindly help me to sort out this Issue .

Did you restart the listener after changing the ip address in listener.ora?
Also check /etc/hosts file...
If your server IP is changed then you need to make changes in listener.ora and tnsnames.ora only..

File system /oracle/SID/sapdata3 empty after EP 6.0 installation

Hi Friends
I'm installing EP 6.0 on WAS 6.40- SR1, AIX 5.1/Oracle 9.2.0 central system, where the Oracle database & the central instance are installed on the same host using the standard SAP DVD's, the installlation guide "SAP Web Application Server Java 6.40 SR1 on AIX: Oracle - Planning & Preparation" specifies creating 4 filesystems /oracle/SID/sapdata1,
/oracle/SID/sapdata2, /oracle/SID/sapdata3, /oracle/SID/sapdata4.
I created the 4 filesystems but notice that after completing the installation with portal up & running, filesystem /oracle/SID/sapdata3 is empty, with no directories & files created inside. Can anybody advice if this filesystem doesn't gets any files, then why SAP document asks to create this in 1st place.
Thanks & Rgds,
Abhishek

Hi Abhishek,
Kindly go through the sap note 972263, it clearly explains the file system required and the size.
SAP NetWeaver 2004s SR2 Java:
File System Name Space Requirement
/oracle/<DBSID>/sapdata1 1 GB
/oracle/<DBSID>/sapdata2 3 GB
/oracle/<DBSID>/sapdata3 - GB
/oracle/<DBSID>/sapdata4 6 GB

BKI0062E: The input file /oracle/SID/sapbackup/.file.lst is not valid.

Hi all,
   It has the following platform: SAP ECC6 in AIX 6.1 with Oracle Database
My question is: When I run a online backup from DB13 with util_file I have this error message :
BKI0062E: The input file /oracle/SID/sapbackup/.file.lst is not valid.
Knowing when I launch from the standard profile on Disk initSID.sap it works without problem
When we test manually with oraSID it works but by SIDadm its not work
Then you can mention or in configuration files BACKINT both users oraSID & SIDadm have rights to use
Many Thanks

As you see - your br*tools are more than two years old, many many errors have been fixed since. I would install the latest tools and try if the error is still there. You can even do that when the system is running.

Hi,
Please note that in fact the error BR0372E File ... has been already reported as saved by backup utility is not an error issued by brbackup tool but by the backint which is third party tool.
As the backint is a third party tool, you will need to contact your Netbackup partner to assist with solution.
