Possible To Have Oracle RAC Standard Edition With 3 Nodes Of Intel Quad Core
Feb 5, 2013
I read that Oracle RAC which is bundled in Standard Edition can support at max 4 sockets. One of my client has a proposal of using RAC but for 3 nodes each using single 1 quad core Intel processor. As far as i understood, an Intel quad core is a multi chip module and actually is a combination of 2 modules dual core, so each Intel quad core may be counted as 2 sockets. Which yield to the proposal of my client will be failed, as the total number of sockets in it will be: 2*3=6 that exceed the max 4 support.
The only supported technique for converting an EE database to SE is export-inport, as documented in note 139642.1. Our client is reluctant to do this because of the downtime involved. It is however possible to open the EE database from an SE home, no problem.
The note says only Quote:When you just install the Standard Edition software, you will end up with Data Dictionary objects which are of no use (or perhaps even invalid) and possibly create problems when maintaining the database.
I have requirement where replication should be done between two 11gR2 RAC on Standard edition.I have following queries,1. Does Standard edition support DDL capture?
Im asking this because on
[URL]......
it says "SE1/SE: no capture from redo" what that really mean ??2. Can it be possible to configure capture at schema level and skip only some of the tables / triggers ?
We are upgrading from oracle 9.2.0.8 to 11g r2, and both are Standard Edition database. The database is part of a product that runs on a customer site, and won't get bigger than 50 GB. It runs in archive mode, and our backup script does a hot backup every night, plus copying the archive logs, redos, controlfiles, etc. We save 2 entire backups - from the last night plus the night before last. Then there's a tape backup that saves the backed-up files to an off-server location.
This architecture has allowed us to recover our customer's data from many odd occurrences at customer sites (power loss during a hot backup, corrupt controlfiles/datafiles/archivelogs). My question is, given that we are running the Standard Edition database, which doesn't have most of the useful RMAN features, is it worth it to switch to RMAN?
I took an Oracle Backup and Recovery class and posed this question to the instructor, and the response was, it would be better to use RMAN over a manual user backup script. Our backup script is pretty battle-hardened - is that the best reason?
my customer wants to create a standby database for his production database (Oracle Standard Edition 11g R2 @ Windows 2008 R2 64 Bit). Now any proof-of-concept which explains shortly the concept and how to achieve it.
In our current setup we have RAC on standard edition and client is now planning to go for Enterprise Edition but not yet decide because of cost. Is there any difference between Grid Infrastructure 11gR3 Enterprise edition and Standard Edition ?
They told me to first install Enterprise Edition and then will move to Standard Edition if they can't get the EE license so in that case do i have to re-install Grid infrastructure for standard edition?
Recently we have downgraded our database from enterprise to standard edition.....our sga size before downgrade was 11 gb and now it is 11gb and there is no as such problem in database..I have read somewhere that standard edition doesn't support sga size more than 2 gb .
I am checking out licenses. We all know that EE is much more expensive than SE. But many customers do have EE installed - unsure if they need all the features at all. After several years of production, a downgrade is considered 'risky' and we continue to pay the full EE.
How can we check and be sure that a downgrade to SE would not be any problem?
Some checks include: * partitioning used in user schemas? --> no downgrade to EE * bitmap indexes in user schemas? --> no downgrade to EE
How can we complete this list, or is there some script to make this easy?
In my production ENV there is two node RAC database is running , and on both machine RAM size is (35GB on node1,41GB on Node2) and other configuration is like below.
when migrating from 32 bit Linux to 64 bit Windows version on database standard edition, is there a server media needed?if yes, can you give me more details on what it consists of?
How many records could I have in a single table without performance degradation with Standard Edition without partitioning with cutting-edge server (8 or 12 cores, 72 GB RAM, FC 4 Gbit, etc...) and good storage?
300 Millions in only one table with 500K transactions / day is too much?

When I arrive to the point 5 I see one resource ora.DPCTTest.db ONLINE on one server (server02 or server03 that are the nodes I want to remove). If I execute:
crs_relocate ora.db_name.db
I obtain: [oracle@server03 bin]$ ./crs_relocate ora.DPCTTest.db Attempting to stop `ora.DPCTTest.db` on member `server02` Stop of `ora.DPCTTest.db` on member `server02` succeeded. Attempting to start `ora.DPCTTest.db` on member `server03`
Initial situation: Oracle 10g database single instance on Windows 2008 (datafile within NTFS partition) Final situation: same database upgraded to Oracle 11g r2 on a two nodes RAC on Windows 2008 (datafile within ASM)
In your opinion, is this the best way to achieve the job ?
1) on the two nodes install grid 11gr2, asm, rdbms 11g r2 (SE) 2) export full from 10g 3) create a new empty 11g r2 database in the RAC 11g r2 infrastructure with the same tablespace layout of 10g database 4) import full from 10g to 11g r2
i am have a problem with Oracle user equivalence. long time ago, we have created Two node RAC. that time, we configured Oracle user equivalence.
today when i am trying to install Oracle Agents on this RAC pair, installation was failed due to Oracle user equivalence. not sure how it happened, and i was confused too.
if i configure Oracle user equivalence again, will it cause any problem to my RAC setup?
is there any way to find, when was the Oracle user equivalence was changed/ ssh keys got changed?
I have a Windows 2003 VirtualBox instance, to which I assigned 3 out of 4 cores my laptop has. This is a demonstration environment for an Oracle vertical product. I got it from my colleagues. The OS boots without starting the DB services - I did this deliberatley while trying to figure out what is happening.
About 2 and half to 3 and a half minutes after the service is started the oracle.exe "latches onto a core and does not let go" (as best as I can describe what I see). With 3 cores I see 33%-34% cprocessor use in the task manager with oracle.exe doing all the using. Nothing else is started. There is no process of which I am aware which actually uses the DB. I only start the TNS listener and the database service.
Once I start it, the demonstration software uses the database extensively for complex queries. With one of the 3 cores 100% used by the oracle.exe I am running short on CPU at times, which makes the demonstratin seem slaggish, and queries take longer than is really acceptable (not surprising seeing oracle.exe is very busy doing I know not what).
I saw big size .core file is generated in $ORACLE_HOME/dbs folder even when no dump dest parameter is set to dbs folder. How to check what causing this genrarating of these files.
10g Oracle Standard Edition RAC feature and how it is charged. I mean: is it free option for Standard Edition or payable?
I read something about Baby Rac on wiki and there was information that only with Engerprise Edition RAC is an extra-charge option for Standard Edition RAC is included.
[URL]......
Quote:Oracle Corporation includes RAC with the Standard Edition of Oracle Database (aka Baby RAC), but makes it an extra-charge option for the Enterprise Edition
We do have corporate licencing model in our firm, so we can evaluate what version of Oracle we need to install (One, Standard or Enterprise) bu there is no matter what version we chosed, because our licensing model give us possibility to install the highest version. So usually we were choosing the Enterprise Editions.
But only limitation for us is an options. We can't have additional option like partitioning, RAC, Oracle Tuning Pack, etc... in order to have additional option we need approval from our financial management.
I have idea to change one of our installation from Enterprise Edition to Standard Edition in order to have RAC option for free. Like i said. If we want to have RAC in our Enterprise Edition we need additional approval of money expense - but this is not easy. But our licensing model give us possibility to install Standard Edition of Oracle instead or Enterprise Edition and have RAC option include without additional expenses.
I have a server with Red Hat EL 5.5 running an oracle database 10g R2 and an Oracle Agent 10.2.0.5The disk ran out of space and I realized that there are a lot of files stating with core.xxx such as :
-rw------- 1 gridagent oinstall 17M Aug 2 13:10 core.10348 -rw------- 1 gridagent oinstall 17M Aug 2 13:15 core.10827 -rw------- 1 gridagent oinstall 17M Aug 2 12:30 core.4129 -rw------- 1 gridagent oinstall 17M Aug 2 12:35 core.4772
What's that ?Why are those files generated at $AGENT_HOME/<HOST>_<SID>/sysman/log/ ?
There are more than 24 GB of those files

I want to do horizontal fragmentation of a table say employee. But fragmentation is often related to distributed databases. So i want to ask how can i do this on my single home computer? list out the steps that should be performed. I saw the concept of link but really failed to understand that.
I have downloaded oracle 10g express edition. I have tried to connect forms 6i in that in windows xp environment but when i tried to connect it is not connecting and giving "don't send" error.
If there is any patch to connect forms 6i into oracle 10g express edition.
I am running Ubuntu 13.04. I am attempting to install Oracle XE 11g R2. It seems that everything was fine until I got to configuration of the database as root I ran /etc/init.d/oracle-xe configure command. I have received the following output Starting Oracle Net Listener...Done Configuring database...
Database Configuration failed. Look into /u01/app/oracle/product/11.2.0/xe/config/log for details
When I look at the logs I get the following error ORA-01034: ORACLE not available. After receiving this error I have attempted to start Oracle manually.
