Server Administration :: Create Multiple Database In Single Server
Apr 18, 2011
I have database in single server. I already have ORACLE_SID=stagedb. So i want to create new sid and named as proddb.Is it possible have multiple db in single server? This server not running as RAC. It run as single only.
I want to install oracle 11.2.0.2 single instance database on AIX 6.1, does oracle recommend separate OS user for grid infrastructure and for oracle install? how many groups I need to have for these users like oinstall, dba etc?
A single master schema where many developers are accessing. all share same password.
now i would like to trace all the changes made by each users. so i create a individual users for all and grant permission to access that schema.do i have a possibility of auditing the changes did by each user for that particular schema
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production PL/SQL Release 11.1.0.7.0 - Production CORE 11.1.0.7.0 Production TNS for Linux: Version 11.1.0.7.0 - Production NLSRTL Version 11.1.0.7.0 - Production
My os version is
Linux damdat01 2.6.18-128.7.1.el5 #1 SMP Wed Aug 19 04:00:49 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
i am installing oracle database 8.1.7 on dell server power edge 2650 first time database successfully installed but when i want to crate new database by Database Configuration Assistant it is not working for new database creation.
I am installing Oracle 12c R1 on Windows 2012. The windows is configured as a domain controller. I am logged in as the domain administrator.I created a normal domain user -- DomainNameORACUSER. I provided this as the existing user id during Oracle installation.
The software installs fine, but when creating the DB using the database configuration assistant, an error is shown "error in process:...inoradim.exe. Enter password for Oracle service user: DIM-00019: create service error. O/S-Error: (OS 87) The parameter is incorrect". The DB is not created.
I skipped the db creation and completed the installation. When tried to create the db using the database configuration assistant after installation, I received the same error.I performed the same installation on Windows 8 and was successful in creating the db.
create a new DB service and apply the load , then I need to verify the service load from Enterprise Manager or table V$SERVICEMETRIC .
Below are what I did
Quote:I tried to add service in tnsnames.ora like below
SERVICE = (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(PORT=25057)(HOST=dadvmc))(CONNECT_DATA=(SID=tgc4)))
/************ Also I tried the serviceName like below, but not working when I conneted SALES1 from sqlplus SALES1 = (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(PORT=25057)(HOST=dadvmc))(CONNECT_DATA=(SERVICE_NAME=host.us.xxx.com))) **********/
and login as
sqlplus scott/tiger@SERVICE[/email][/email]
then lock table EMP in exclusive mode in two session.
I can see the load is added to service SYS$USERS , but I can't see the new service from V$SERVICEMETRIC or Enterprise Manager.
I have install Oracle 10g Database software in Red Hat 5.9 64bit. When I want to create a database manually (not using DBCA) I am getting errors like follow:
[oracle@t24app2 ~]$ export ORACLE_SID=dbend08 [oracle@t24app2 ~]$ sqlplus / as sysdba

we are having physical standby database and production database..we have create a soft link for a datafile in production to another mount point
ex- /disk1/data1 to /disk2/data1
now we want to keep the datafile in /disk2/data1 and remove the softlink..As we are having physical standby database . i need to know what are step to be taken. my action plan is as follows:
In production.
1. synchronise both standby(apply archive logs) and production. 2.shut down the standby 3.create controlfile in production in ascii format and edit the path (/disk1/data1 to /disk2/data1) 4. run the @control.sql that i have created 4.create a standby control file in production .
In standby:
1. take the backup of controlfile. 2.place the newly create controlfile(from production) to the location of controlfile 3. remove soft link. 4.startup mount. 5. then we can apply logs as usual to make the standby sync.
whether my action plan is 100% correct or any changes to be done.
Find an appropriate script to automate Oracle DBs in one server? This db server have 6 instances. We always done the starting up and shutting down manually, although we have a reference script that does this but in Oracle v7.3.4. We do want to include the automatic start/stop of dbconsole for accessing it via OEM.
Through an Oracle Apex application I need to create/drop a user/schema in another Oracle database. i.e., create/drop user remotely using an Oracle Apex application.
A DB server (Oracle 11g) on Linux will support a Web Application Server (Java based) for hosting a public web site.For sending multiple INSERT statements over from the Java Server to Oracle Server, I have two ways to do it:
1) Wrap those insert statements together and send it over with one connection to Oracle
2) Send each insert statement separately to Oracle. As the result, multiple insert statements are sent and accordingly multiple connections to Oracle are needed.
Advantage of option 1 is just using one Connection. Disadvantages are that Oracle will then need to parse the statement string into multiple separate insert statements, and then loop through them to execute each. This may be costly in CPU sense.
While the option 2 may have quicker execute of each insert statement, but will need to create multiple connections.If the number of users is known and stable (such as intranet), I would prefer option 1; while for the internet there could hundreds concurrent users at the peak, I lean towards the option 2.
1)How a single control file is enough to have all the transaction's SCN no for older transactions.
Eg - A transaction has the SCN 01 and after a month the new transaction's SCN is 502. Is the control file holding all those (01 to 502) SCN in it or just will have the latest SCN no (ie - 502).
i am trying to install Oracle 10.10.2.0 on Windows Server 2003 standard x64 Edition Service Pack, but when i try to run the installer or open DVD it gives me below error.

I have to migrate production database version 10gR2 on windows 2003 server to oracle 11gR2 on windows 2008 server . So far i have just installed the oracle software on 64bit windows 2008 server. How to move the data or migrate from old server to new server .
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
database administration , we are planning to use amazon cloud database , this database does not allow us to login to server machine , unfortunately amazon don't provide ssh to this machine , in general for doing any of adminstration task on the database will there be need to log into the machine ? we can always log in through toad or any other sql client but we cannot do ssh to server..general can this limitation effect administration ?
I recently installed Oracle 10g on my windows Xp laptop. It has become considerably slow since then. I want to start the database server only when I need it, and not every time I start my laptop. I looked around in OEM and did found a way.
I am connected as System. It was the only user I set-up a password when installed the database on personal computer.
