Ideal Configurations for datawarehouse database ?

Dear All,
Is it ideal to configure the builder and runtime repository on a separate Oracle 9i database so as to have a superior performance ?
Will the the builder and runtime repository give good performance if it is configured on a database that is already handling OLTP transactions ?
Which is the most ideal one ?
Where can I find the recommendations for creation of a database (init file parameters) for only warehouse purpose ?
Can anybody please help me ?
Thanks in advance.

Hi,
See answers below:
Dear All,
Is it ideal to configure the builder and runtime repository on a separate Oracle 9i database so as to have a superior performance ?Usually there is not much difference, although it might be a good idea to have the design repository and run time on a separate instances in case the workload pattern of a design environment might affect the performance of a runtime environment. Depends from the specifics of your case.
Will the the builder and runtime repository give good performance if it is configured on a database that is already handling OLTP transactions ?This is definitely a no. A transaction system is usually tuned for optimal transaction processing (data insert and pinpoint queries) while a data warehouse (the runtime) is optimized for a fast performance of large queries. Therefore the configuration of these systems are very different. Furthermore, the two systems usually have a vastly different operational modes (backups, data archiving, availability etc.). For all these reasons, it is usually makes sense to have a data warehouse on an instance which is separate from the transaction system instance.
Which is the most ideal one ?
Where can I find the recommendations for creation of a database (init file parameters) for only warehouse purpose ?For more info on the Oracle 9i data warehousing take a look at the Data Warehousing Guide:

How will you find out no of standby databases configured for primary database from OS level

How can find the number of standby databases configured for primary database from os level

Check the alert log.
The Alert log will always have Data Guard messages in it.
Example
cd /u01/app/oracle/diag/rdbms/primary/PRIMARY/trace
tail -1700 alert_PRIMARY.log | more
Wed Nov 13 13:35:26 2013
ARC7: Standby redo logfile selected for thread 1 sequence 1164 for destination LOG_ARCHIVE_DEST_2
LNS: Standby redo logfile selected for thread 1 sequence 1165 for destination LOG_ARCHIVE_DEST_2
If you don't see messages like this it's probably not a Data Guard system.
Or search it for :
System parameters with non-default values:
Which on Data Guard system will show things like:
log_archive_dest_1 = "LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=PRIMARY"
log_archive_dest_2 = "SERVICE=STANDBY LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=STANDBY"
log_archive_dest_state_1 = "ENABLE"
log_archive_dest_state_2 = "ENABLE"

Data Guard configuration for RAC database disappeared from Grid control

Primary Database Environment - Three node cluster
RAC Database 10.2.0.1.0
Linux Red Hat 4.0 2.6.9-22 64bit

After adding a logical standby database through Grid Control for a RAC database, I noticed sometime later the Data Guard configuration disappeared from Grid Control. Not sure why but it is gone. I did notice that something went wrong with the standby creation but i did not get much feedback from Grid Control. The last thing I did was to view the configuration, see output below.

Here are the steps followed to add the standby database in Grid Control

Add standby database
Create a new logical standby database
Perform a live backup of the primary database
Specify backup directory for staging area
Specify standby database name and Oracle home location
Specify file location staging area on standby node
At the end am presented with a review of the selected options and then the standby database is created
Has any body come across a similar issue?
Thanks,

Any resolution on this?
I just created a Logical Standby database and I'm getting the same warning (WARNING: No credentials available for target ...) when I do a 'Verify Configuration' from the Data Guard page.
Everything else seems to be working fine. Logs are being applied, etc.
I can't figure out what credentials its looking for.

As Anurag said, we don't even know that what version you are on at the moment and what's the need of your business. So it wouldn't be possible for us to tell what you should put in your db regarding 10g. Interestingly, you mentioned that you are running 10g so what features you saw in 10g that raised eyebrows of yours, none is it? Since you have asked , I would give a try to the new EM given by 10g but that's just one of the may new features and only you would decide what fits for you and with your application.

EM console HA page says "Data Gaurd not configured for this database"

I am attempting to use EM console's "High Availability Console" to create a standby database, but, the option is not available. Under "Data Gaurd Summary" the page shows "Oracle DataGaurd is not configured on this database."
How do I configure this option so that I can use the console to create Standy databases? I have looked everywhere I can think of and cannot find any instructions!

Click on your database name, and you'll be lead to a page which shows you all the statistics of your Db
Click on the "Availability" Sub Tab.
You'll see the option to "Add Standby Database". You can take it from there. (you'll be prompted to log in to your database -- log in with sys)
Now click on "Add Standby Database"
The process I normally follow is this
1. RMAN your primary
2. Create standby control file from primary.
3. Get your init file from primary
4. Copy everything over.
5. Make the init file changes (fal client, fal server on primary, any kind of directory mapping, point the init file to the standby control file on the standby side)
6. Bring up the standby db (doing all the other changes that are required)
Then you can import that Db into OEM,
or you could just use the Wizard from OEM :)

How to choose a right server for Oracle Database!

Hi all,
Is there any formular that allows me to find the appropriate server configuration for Oracle database 11g?
Please help!
Thank you all.
Dan.
Edited by: Dan on 01:45 06-01-2013

Simply put ... no.
Determining the correct server is a dance between hardware vendors (one point of input to be treated with general distrust), internal expertise and experience working with similar systems, and most importantly understanding the behaviour of what you are building.
Here are some sample questions to start the ball rolling.
1. What operating system expertise does your organization have?
2. What operating system expertise is readily available in the community from which you hire applicants?
3. What type of application?
4. What are up-time expectations?
5. Requirements for high availability?
6. Requirements for time to perform a full recovery?
7. Requirements for security?
8. Storage footprint (dictates internal storage versus SAN, NAS, or ZFS)
9. Anticipated growth (3-7 years)
Everyone wants to sell you CPU clock-ticks, more RAM, more IOPS, etc. But the first thing you need to understand is the capabilities you require that are generic: Required of any solution. Only when you have a clear understanding of these factors are you ready to discuss whether the solution is a pizza box or an ODA ... an Exadata or an IBM System Z.
Far too often I find people purchasing RAM they don't need with CPU speeds that exceed the ability of their network infrastructure to move the data so pay special attention when you are ready to make your purchase to engineered systems like the ODA.

External drive configuration for iMovie events

I have a lot of old 8mm & mini dv tapes, that I want to get transferred to external hard drives to edit in iMovie. Once transferred, I plan to back them up and store the backups, then edit and organize. I just upgraded to a new iMac and do not have the firewire 400 port any longer. It seems that the USB connection would be too slow to do iMovie editing on external drives. I would like to use internal drives in a dual or multi dock.
I have several 500G, firewire 400, external hard drives, daisy chained together that I have already I filled. They take up too much space, outlets and cables, so I'm switching to internal drives with a dock.
Someone mentioned that you can get a dock that holds multiple hard drives, which seems might allow faster transfer speeds between them for editing, between the drives. (as well as need less cables/outlets, etc). If I am editing in iMovie, I would think a firewire 800 dock would be preferable versus a USB.
I've seen dual USB 2.0/eSATA (or USB 3.0 docks, which I don't think Apple is supporting right now). Can you use a dual eSATA drive with an iMac (can you use an adapter)?
I also saw some 4 bay towers online, but I don't think that's what I'm after. I'm not sure that I would be swapping them alot. I would like it all together in order to create projects with clips from various years.
So I'm wondering what would be the ideal configuration for iMovie editing on a new iMac? I am thinking a firewire 800 dual dock might be ideal (I am sure 2-2Tb internal drives should be more than enough to hold all my video, until I edit it down). Would that be too sluggish? I guess I could work with 2-1Tb drives and swap them out, if that would be too much.
Any recommendations on a dock? Newegg has a pricey dual IcyDock with FW 800 for $180

How to configure different listener for each database in 11gR2 RAC

Hi Friends,
Current Prod Setup :
11gR2 (11.2..0.2) RAC on RHEL 5.5 with 3 SCAN Listeners on default 1521 port.
Having 4 databases which are using SCAN-IP and listening on default port only.
As per policy, we have to create separate listeners (on different port) for each database.
like,
DB1 - 1522
DB2 - 1523
DB3 - 1524
DB4 - 1525
Even If I configure 4 listeners using NETCA, how my failover & load balancing will happen using SCAN & Newly Created Listeners ???
Thanks in advance..

Manish

Hi,
I tried on 11gR2 TEST RAC Server to have different listener with different port (1529) for SCAN & Node Listener & tested failover, load-balancing which was successful.

Hi,
You need to a script and run it on os level. Here is an example:-
emcli relocate_targets -src_agent=agentmachine1.domain:3872

Database is configured for Data Guard

I am run a UTF8 conversion on a development database that has been cloned from Data Guard. There is a warning in Migration Status: "Database is configured for Data Guard" What is the DMU looking at to determine this? The database is open in read-write mode and it behaving like a primary database (I run the DMU scan and run updates to fix invalid representations). I would like to know what settings I need to update.
Is this preventing me from converting tables using CTAS? When I try to select this for all tables I get the message, "The DMU does not support the conversion method "Copy data using CREATE TABLE AS SELECT" for tables that are involved in an Oracle Streams process, like capture or apply. Use another available conversion method for the table"
Thanks,
Ben

The DMU checks if the parameter DG_BROKER_START is set to true.
The problem with CTAS is independent from Data Guard. The DMU checks for tables that:
- are source of asynchronous Streams capture, or
- have update conflict handlers, or
- have DML handlers, or
- have conflict resolution parameters
The above tables are considered configured for Oracle Streams and are not supported by CTAS conversion method. This is because the CTAS method creates a converted copy of the table and drops the original. The DMU is not capable of moving the Streams configuration information from the old table to the new one.
Thanks,
Sergiusz

Multiple database configuration for scan ip.

Hi All,
I am planning to implement 11gR2.
Grid infrastructure is already done. Now i need to create 4 database in the same oracle home.
There is a separate listener for each database with different port.
As i scan ip is configured using 1521 port.
My question is will my scan vip will work to connect to the database remotely if will give tnsstring with scan ip.
For e.g
for database 1, we are using port 1522
MYDB
(DESCRIPTION=
(ADDRESS=(PROTOCOL=TCP)(HOST=t24db-scan)(PORT=1522))
(CONNECT_DATA=(SERVICE_NAME=master)))
for database 2, port is 1523
MYDB
(DESCRIPTION=
(ADDRESS=(PROTOCOL=TCP)(HOST=mydb-scan.ORACLE.COM)(PORT=1523))
(CONNECT_DATA=(SERVICE_NAME=master))
Please suggest ,
Thanks and Regards,
jatin

Jatin,
If there is a request to bring down a database, you will just shutdown that database. You should not shutdown the listeners, as they serve other databases.
Now that all listeners are running out of GRID Home (not database home), this is totally managed by CRS. We dont have to worry about managing them.. lets just manage the database. Same applies to patching also.. you need to bring down all services in the database home to apply the rdbms patches.. at this time, listeners can still be up (as they are not running out of database home).
Thanks,
Raj Mareddi

Is OEM database control configured for the DBs?

Hi,
WE have a RAC setup on 2 nodes and now we want to change the default listener port for RAC database.
Database ver: 10.2.0.4
We now that srvctl does not work to add listener manually to CRS.
We are now using netca to create new listener on both the RAC nodes but it gives error throwing :
Problem in configuration : Node(S): hostname
Try again...
When we try to start the listener say listener_I it throws following error:
Problem in configuration :node1
