Cons Of Running 8 Production Database Instance On One Windows Server
Dec 3, 2010
We are planning to consolidate our Oracle Production DB into one server. We are basically a windows shop. Is it feasible to run 8 production Oracle DB in one windows server. All the DB are not really transaction intensive DB. 2 DB in the size of 300GB and others all DB falls under average size of 40GB.
I can take care of the HD slicing so Oracle does not enter into IO bottleneck. We are planning to go for external NAS or SAN for storage.
My main concern is on processor usage. The processor we are thinking about is Intel Xeon Quad Core x 2nos. Will there be a processor bottleneck or is there way in Oracle to assign processor usage(I belive there is no much tweaking options here)
I ran "exp" command to take a back of Oracle Db based on user and later imported(using "imp" command) the dump into another db. Its seen that some the tables are not exported during exp command run. Can I use exp command on Oracle 11.2 version?
I have to migrate the current production database to test 10.2.0.4 on windows. Any non-export way to upgrade 9i to 10 g?
i have following steps
1) ALTER DATABASE BACKUP CONTROLFILE TO TRACE 2) shutdown oracle 9i database on server A 3) copy database file, controlfile, redolog, and other files to new server B 4) alter the controlfile backup with new location of bdump, udump, and log file and data file locations 5) user oradim ORADIM -NEW -SID SID [-INTPWD PASSWORD ]-MAXUSERS USERS -STARTMODE AUTO -PFILE ORACLE_HOME\DATABASE\INITSID.ORA 6) start dabase in upgrade mode 7) run catpat.sql and util102.sql 8) take backup 9) open database for users
I was install windows 7 on my computer,oracle database10g and forms 10g installed successfully. I Cannot run forms on the browsers , how i can run my programs
I will have to proceed with Oracle 9 database refresh from production server to integration server. 5 biggest schemas must be exported and imported. They constitute 97% space used in a database. This is very big database so I would like to be sure that everything will go smoothly. That is why i want to ask you some questions.
Have you got any clues for me before I start with exp/imp? From my side i will tell you that I will have to exp/imp schema by schema because there is small space both on production and integration disk for a dump. First thing I thought are dependencies between schemas that are exported and that which are not, and also between schemas that are exported/imported one by one.
This is procedure that I plan:
For every schema that is to be refreshed { 1. Export schema with ROWS=N CONSTRAINTS=Y 2. EXPORT schema with ROWS=y CONSTRAINTS=N 3. Import schema from step one 4. Disable all the foreign key constraints using ALTER TABLE DISABLE CONSTRAINT. 5. Import schema with rows } ALTER TABLE ENABLE CONSTRAINT
With above procedure i think that I will avoid problems with dependencies between schemas exported/imported one by one. But my concern is if there are any dependencies between those schemas and schemas that are not exported. Is there an way to check it before refresh ?
There is an issue with the 32 bit Oracle client on 64 bit windows where it cannot connect to the database throwing the error ORA-12154: TNS:could not resolve the connect identifier specified.
Since all the 32 applications will have the path C:Program Files (x86) on 64 bit windows, The PATH variable doesn't recognise (). This issue was there in the previous versions of Oracle Client. But the bug has been fixed in Oracle 10.2.0.3 32 bit client. Still the user is facing the same issue.
Oracle Client: 10.2.0.3 32 bit Windows OS: Windows server 2008 R2 64 bit
I have referred document [ID 334528.1] from the metalink(which states that the bug is fixed in 10.2.0.3 client).
I need to use Data Pump for the first time on my production Database.Currently on Testing Database, when i am taking schema level export there are no errors or warnings in the log file but when i importing it gives fallowing ORA in the import log file. i searched on google,the only way i found is to recompile the invalid objects. how to avoid this warnings in log file.
"ORA-39082: Object type ALTER_PROCEDURE:"QUANTISV4"."P_CTM_ABN_INVST_EQUITY" created with compilation warnings"
We have quite a number of sessions in database MES (production) coming from another machine.
From v$session, the program is oracle@WID27 (TNS V1-V3). This WID27 (hostname) consists of quite a number of development databases inside. We have to trace which jobs are actually triggering this, as WID27 are not suppose to connect to production databases.
How can we tell whether the sessions came in is from dblink or from the machine itself?
I have been asked to create a new instance of an application server. As part of this, my management has asked me to replace any old JREs or JDKs.
We run 10g, so I installed the 10203_vista_w2k8_x86_production_client on my new server. I would like to replace the 1.4.2 JDK that is bundled with the Oracle Production Client with 1.6.0.
I have Oracle 11g R2 (11.2.0.1) with Oracle EM running on Solaris 10 with ZFS.When I start OEM it comes up and tells me that the listener is running but that the DB instance is down and agents are down.I know that the instance is up because I can start it manually.
Each time I start emctl, lsnrctl and DB manually everything starts running but OEM returns a failure for the DB. long as the display shows the DB not running OEM won't allow me to work in it.Instead of getting the login page I get the Database Control Page stating that "Enterprise Manager is not able to connect to the Database instance."I have tried the various emca -config dbcontrol db -repos drop and recreate but no luck.
Is there a way to uninstall/reinstall without dropping the DB?Are there control/configuration files I may hack to tell OEM the correct information?
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?
- one ASM instance - X DB instances - each DB instance uses 2 or more dedicated diskgroups from the ASM instance - there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view - the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?
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.
I am using oracle 10g with data guard configured , I have primary ( A ) and standby database ( B ) .But because of some unavoidable conditions the primary database ( A ) got shutdown and was not starting , We shifted the standby database ( B ) at new location and changed it to primary with following command ,
startup mount; alter database recover managed standby database finish; alter database commit to switchover to physical primary; shutdown; startup;
This new primary ( B ) was open for end users for 2 days during which old primary ( A ) was shutdown .
I took the backup of ( B ) and restored it on A AND shutdown the B . Now A is acting as Primary database. Server B is shutdown . I want to change server B to standby database with A running as Primary .Is it possible ?
We've been administering a multiple instance production dB server with 3 different versions of Oracle installed.Currently, each of Oracle version had corresponding listener.Oracle 9i had 2 instances, 10g 6 instances & 11g 2 instances also.how I can integrate this 3 listeners into 1.
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 .
