Tnsnames configuration for RAC and dataguard

Hi everyone,
I have an environment with RAC and dataguard (production is RAC, standby is single instance) and I was wondering what is the best way to configure the clients (since I have quite a few and I don't want to change their tnsnames if I need to failover to the standby database).
Now, I need to have both RAC nodes of course, the question is what I should do with the standby...
The problems are:
1. If I add the standby as another address, 1/3 of the connections will get to it and I don't think it's a good idea
2. I can disable the load_balance, but then all connections will go to the first node's listener
3. After a failover, if the RAC nodes are down, it will take a long time to connect (the servers will not respond and the client will wait for timeout if it tries to connect to the RAC nodes first, only after the timeout it will try the standby and succeed)
Any ideas and suggestions will be appreciated.
Thanks,
Liron

Hi Robert,
I agree that the standby should be up, but you have to admit that if it is down it should not delay connections to the primary...
About the DNS, it's not that I don't trust the SA, but this is an environment for a customer so it should be as independent as it can be. So the failover process will be easy and fast. I don't know if I can get DNS permissions, but that's a good idea...
A question that can be derived from this:
assuming that I use observer to have an automatic failover, how should I configure my TNS? If the standby will become the primary automatically, I have to configure the clients to connect to the activated standby automatically. With no DNS changes or anything manual.
I guess in this case, my best option will be with LOAD_BALANCE=off, some of the clients will have RAC-NODE1 as first address and some will have RAC-NODE2, the standby will be the last address and we'll suffer the timeout if the primary will be down when connecting to the activated standby.
If anyone has other ideas, it would be great.
Thanks,
Liron

Infrastructure suggestion for Oracle RAC and Dataguard

Hello,
We are working on migration business proposal and need to suggest HA and DR infrastructure solution with Oracle 11G databases. I am thinking to suggest Oracle 11g RAC and Dataguard to meet this requirement. We also wanted to cover Dev, Test and Pre Prod along with Prod in new environment. Can someone suggest cost effective, stable and scalable infrastructure for this requirement
Best regards,
Venkat

In terms of cost ? Perhaps.
In terms of performance? NO.
Bear in mind I'm not trying to sell anything here, but in my experience hardly anything matches the performance of Exadata. It has specific features for the DB such as de iDB protocol which enables the offloading of queries to the exadata storage servers. More unique features include: storage indexes, HCC compression, smart flash cache... It's all a matter of how much you want to spend.
Yes, you can have all your servers on the same box if you want, just make sure it is not a single point of failure. (Have appropriate safeguards in place in case of power failure, Data center catastrophes, etc). In case of LPARs on the same box, be aware of one server over-utilizing resources which would affect the other LPARs (configurable).
More info on Exadata: http://www.oracle.com/technetwork/server-storage/engineered-systems/exadata/dbmachine-x3-twp-1867467.pdf
If your company has a tight budget you might also look at your options with Database appliance: http://www.oracle.com/technetwork/server-storage/engineered-systems/database-appliance/documentation/oracle-db-appliance…
Database appliance has more flexibility in terms of licensing and it's also a complete hardware solution from oracle for Databases.

RAC and dataguard

With reference to this thread
is Dataguard and standby dbs is HA
RAC and DATAGAURD are two different approches for high availability and desaster recovery.
We are planning to implememt RAC and DATAGAURD but there are budget issues also.
With RAC As i understand we have multiple instances governing a single database. So multiple node/machines governing a single database server.
With DATAGAURD,we have a DR solution at another location.If the primary server fails,standby database takes up the role of primary.
With RAC alone,if any node fails, there is another node to do instance recovery or the server still continues. But what if database server crashes. WIth RAC alone and no dataguard, won't it allow downtime?

Hi Hashmi,
RAC and DataGuard are indeed different things, as you understood.
Regarding your question, there is no database server, that's the whole thing. There is one database (which resides on external redundant storage like Netapp, EMC, etc.) and there are several servers that are running the instances. Downtime will occur only if the storage crashes. And if you don't trust your storage you can have ASM redundancy, so storage failure will not cause downtime as well.
The down side, is that there is one database, so if you have logical corruption, human error, or something similar you can loose data or have downtime.
However, the high availability is real.
In DataGuard, once the primary is down it takes some time (not long) to activate the standby, but it has a different IP, so you should configure your DNS/clients (in advance or at failover) to connect to the activated standby.

I will be buying the new IMac 27 inch in December. Would like input on the best configuration for photographic and possibly video processing-dream machine!

I will be buying an IMac 27 inch in December. What is the best configuration for photo and possibly video processing.Does one need a Mac Pro? Dream machine!

Just to explain what I just wrote to Laundry Bleach:
Why is there no iDVD on my new Mac?
https://discussions.apple.com/docs/DOC-3673
UPDATE & ADDENDUM:
But even though you can still buy iLife 11 that includes iDVD 7 from Amazon, Apple now make it difficult to install:
Poster jhb21939 posted this in another thread:
“when I attempted to load iDVD into a new iMac. A notice came up on the screen stating that the 'Authorisation Licence' had expired on 25 March this year (2012).
I contacted the Apple support team and eventually, I was told that the Licence had been withdrawn and could no longer be used.”
In other words Apple are now so adamant that we don’t use iDVD that they have tried to make it impossible to install.
In response, Old Toad posted this solution:
“You can still use it one all of your Macs. If you get an invalid certificate message just set your Mac's clock to sometime before early 2011 and run the installer. After you're done reset the time back to the correct time.” He added this comment:
“It began after iDVD and iWeb were discontued and they were dropped from the Apple Store. All I can think of is the certificate was set to expire after a certain time period after the intitial iLife disc was released.
I've been able to use the installer even without setting back the date. I just clicked on the Continue button and it would work as expected. For some it would not continue unless the date was set back.”
The latest anorexic iMacs just announced do not even include a CD drive! Proof positive that Apple virtually prohibit the use of DVDs - although the newly announced Mac Minis do include a Superdrive.
Yet, they still include iMovie! Heaven alone knows or understands what you are supposed to do with your newly edited masterpiece - except make a low quality version for YouTube?

Oracle data guard configuration for primary and standby db_name

I am working on configuring an active data guard for one primary DB and one standby DB. I have a few questions:
1. Can I use different db_name, db_unique_name and instance_name for primary and standby. For example: primary(db_name, db_unique_name and instance_name)=chicago. When I create standby DB with Rman backup and copy of pfile and control file from primary DB or use Grid control to create standby database. Oracle document or Grid control all keep standby db_name=chicago. Only make standby db_unique_name and instance_name=boston. Due to my application system condition, I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?
2. In primary datafiles, application system generate datafile name like this: hr_chicago_01.dbf, fn_chicago_01.dbf. When I move datafiles to standby server, if I plan to use db_name=boston for standby DB, can I rename datafiles as
hr_boston_01.dbf, fn_boston_01.dbf? In this way, datafile name match up with db_name. but I will create standby log group and members on primary and standby identically. If in future switching over, DB will not have problems.
3. If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standby. Then "alter database backup controlfile to trace" from promary and also " create pfile='/xxx/initSTANDBY.ora' from primary. Then modify init.ora and controlfile. Then run control.sql to bring standby DB up. After that, configure redo log shipping and apply with data guard or SQL. Is this a acceptable way to create physical standby DB?
Please advise your comments. Thanks in advance.

I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?NO. DB_NAME must be the same ("chicago") at both sites. The Standby will be using a different DB_UNIQUE_NAME (e.g. "boston") and can be using a different Instance name / SID (e.g. "boston").
can I rename datafiles Yes. The database file names can be changed.
If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standbyWhat is the difference between the first sentence (a backup of the primary) and the second sentence (a copy of the primary) ? A Copy is a backup.
Are you intending to differentiate between an RMAN Backup and a User-Managed (aka "scripted") backup ?
Normally, for DataGuard, tou can use non-RMAN methods to copy the database but there's no value add in this.
You'd still have to setup DataGuard ! (and I wonder if you'd have complications setting up Active DataGuard).
But remember that you MUST create the Standby controlfile from the Primary and copy it over to your Standby -- particularly as you are planning to use DataGuard. This is not created by 'alter database backup controlfile to trace' , but by 'ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'filename''

Directory Setup for RAC and Oracle Restart

I have three database installations that I'd like some insight on the initial directory structure and permissions. The three installations are:
1) Prod RAC - OEL 5U2, 11.2.0.2 Grid Infrastructure, 11.2.0.2 DB EE with RAC option
2) Test RAC - OEL 5U2, 11.2.0.2 Grid Infrastructure, 11.2.0.2 DB EE with RAC option
3) Single Instance - OEL 5U2, 11.2.0.2 Grid Infrastructure Standalone (Oracle Restart), 11.2.0.2 DB EE
The they all have two users GRID (for Grid Infrastructure Software Owner) and ORACLE (for Oracle Database Software Owner).
We had a consultant install the databases. It's very weird since we have an inconsistency in directories and permission. I want to understand the inconsistency between RAC installations as well as Oracle Restart Install.
SEE BELOW: The two RAC servers have different owners for /u01/app/11.2.0.2 directory. The Oracle Restart Installation - Single Instance has the same owner as Prod RAC but different than Test RAC. What the consultant said was that ORACLE_BASE would be /u01/app/oracle for both Grid Infrastructure and Database installations. This was to apply to TEST/PROD RAC (3 node, 3 instances, 1 instance/node) and Oracle Restart installation. The GRID_HOME would be /u01/app/11.2.0.2/grid and ORACLE_HOME would be /u01/app/11.2.0.2/db_1. It seems like the owners aren't setup correctly. Why? I don't want problems with patching or upgrading. If this setup is technically incorrect what is the best way to setup so there's no owner/permission issues. Is it necessary to have two separate ORACLE_BASE's like /u01/app/grid?

Hello
I did only check prod, as that is the important one.
i am afraid that setup is not clean. I won't use the work is wrong, but need to be normalized.
grid oracle base need to be separate from oracle oracle base, and the grid oracle home, MUST be outside of oracle base/oracle home of the oracle user.
In a multi user setup, the structure should be as follow.
grid user, group oinstall, asm* groups
oracle user, group oinstall, dba and db* groups
The GRID install, have, grid home and oracle base
the oracle base for grid should be, /u01/app/grid
the grid home should be, /u01/app/11.2.0.3/grid
the Oracle user have several homes, and oracle base
the oracle base for oracle should be, /u01/oracle
so, for permissions, when I create this, i do as root
mkdir -p /u01/app/11.2.0.3/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oraInventory
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
then, you install grid .. you have so say oracle home is /u01/app/grid and oracle home is /u01/app/11.2.0.3/grid
at the end, the root.sh as part of the install will take care of the permissions for oraInventory, and the rest for grid.
when grid is installed, you can move to the oracle db install you use oracle base as /u01/app/oracle and oracle home as /u01/app/oracle/product/11.2.0.3/dbhome_1
that will give you

Each user have to use his own oracle_base, as each oracle_base will store files and folders created for logs, admin, diagnostic with different permissions and different usages, for a reason you have role separation.

R/3 configuration for 0SD_C01 and 2LIS_01_S001

Hi guys,
I have activated the infocube 0SD_C01, the complete flow. I created an infopackage for its infosource 2LIS_01_S001 and made an extraction. I got an error with a delta initialization and with a full upload I got that there is no that data in R/3. Im currently using BI 7.0 and R/3 ECC.
Is there something I need to do first in R/3, some kind of configuration for that datasource? They told me for the datasources 2LIS* used the transaction LBWE, but I dont see 2LIS_01_S001 on that transaction.
What do I need to do in R/3, in order to do extractions? Does someone have a manual for this Datasource/Infosource that would like to share? My email is [email protected]
Thanks a lot
Vic

Hi,
There is no LO datasource , you have to use LIS ..i.e, 2LIS_01_S001.
I hope you know the steps to activate and load data into BW using LIS.
Steps are as follows:
1) Activating LIS update - goto OMO1 transaction code
In the Updating Info Structures(S001) - double-click the Updating radio button for Info structure S001.
In the Parameters dialog box select Synchronous updating and choose ok.
2) Goto OLI7 Transaction code - run the statistical update.
3) Goto OLIX transaction code - setup version &( will be copied to actual version 000 for reporting
4)Go back to OMO1 do deactive the LIS Update, check radio button to "No Update"
5)Now goto LBW0 and choose option "Deactivate" Delta updating in LIS.
6) In BW, Replicate DataSource, and run info Package with Initilization.
7) Now again in R/3 we need to "Activate" Delta option from transaction code LBW0.
8) and last step is to goto OMO1 to activate LIS Update to Synchronous updating and save.
From now on you can run your Delta Infopackage

Double the RAM to 32 GB at a minimum.
Use a full size case, not a mid-size. You'll get better air circulation and have room for expansion.
Add a couple more hard drives.
Get a 850w gold power supply.

System configuration for ITS and for BSP

Hi,
I´m looking for the parameters needed in a system to connect to an ITS and also to BSP.
I have created one system to be able to connect to ITS and another one to be able con connect to BSP, both of type SAP Load Balancing system.
The system I created to connect to ITS has the following configuration I entered:
Connector:
SAP Client = 350
Internet Transaction Server (ITS)
ITS Description = myDescription
ITS Host Name = myhostname:port
ITS Path = /sap/bc/gui/sap/its/webgui
ITS Protocol = http
Thats it that´s the only configuration I´ve made.
For the BSP system I entered:
Connector:
SAP Client = 800
Web Application Server (Web AS):
Web AS Description = myDescription
Web AS Host Name = myhostname:port
Web AS Path = /sap/bc/bsp/sap
Web AS Protocol = http
My question is this, is this configutation enough?,
It is working fine with this configuration but I´ve seen some other information where they fill more parameters in the connector section, would this extra parameters in the connector section help in any way or they will just simply be ignored?, We will be using Web Dispatcher for both.
does somebody knows the answer? Is there some documentation on this?
Thanx in Advanced!!
Kind Regards,
Gerardo J

The connector properties are only required if you are planning on utilizing the SAP connector to connect to your backend system.
What you have configured so far should suffice for ITS and BSP applications. I hope you have configured the system aliases already.

1) I have 12 pre-licenced Unified ports on my FI 6248 and I need to configure 1-10 for Ethernet and 11th/12th for FC port.,,,,Is it a valid configuration?
2) If yes tomorrow if I buy the licence for the remaining ports 13-32. Can i continue using them as Ethernet and FC ports in alternate.I know
Ethernet ports/FC ports must be grouped together in a block and they should end with even numbered port.
Looking for your response on this....

Hello Padma,
I am stucked at a point of configuration on my lab and need your valuable advice.
I have 8 SFP-H10GB-CU3M and 4 Nos SFP-10G-SR in my BOM.
My confusion is I have to accomodate these SFPs only in my currect environment.I cant wait for the entire process of re-ordering new SFPs.
So I will have to split SFPs between the pair of FIs and IOMs.
So is it that I am short of SFPs? because my understanding says that I will be needing atleast 4 SFPs(Cu) on both FIs.
So for FI1----> 2 SFPs(Cu) for Server ports,2 SFPs(Cu) for Uplink Ethernet ports
for FI2------> 2 SFPs(Cu) for Server ports,2 SFPs(Cu) for Uplink Ethernet ports
That means all my 8 SFP-H10GB-CU3M are exhausted.
I dont have more SFPs to connect to my 2104 IO Modules.Please suggest me some workaround.I am in process of creating a lab so performance and bandwidth is not an issue for me.
Regards
Deepak

Cloning 11i non split to split configuration with RAC and ASM

Hello Hussein,
I just want to ask some ideas on what is the best way to clone our UAT/DEV environment to our PROD environment.
Right now no RAC and ASM setup for the source system still 9.2.0.5 but the plan is to convert to ASM + 10g RAC.
Can you please let me know on what is the best way to setup PROD out of our UAT environment?
Here's my options:
1. Install a fresh prod system
2. Convert source system to ASM + RAC before cloning to target - setup as below:
(Source)
APPS server - 32bit
DB server (2 node RAC + ASM) - 32bit
(Target)
APPS server - 32bit
DB server (2 node RAC + ASM) - 64bit
3. Clone existing target system (non RAC and non ASM)
copy source APPL directories to target
Install 64 bit Oracle 10g to the target system
clone/convert database source (9i 32bit) to database targer (10g 64 bit) using RMAN.
Install clusterware 11gR2
Convert database to RAC
Can you please let me know on what is the best approach to do this? For fresh install it will take some time to apply the current patch level and applying other patches.
For Option 2, seems a bit complicated to do 32bit - 64 bit cloning on RAC. Appreciated if you can provide doc id for this.
For Option 3, not sure how smooth the conversion from 32bit to 64bit.
Appreciate your insights on this.

jeffrey

Hi Jeffrey,
Since you are on 9.2.0.5, I assume you are running Oracle Apps 11i and not R12.
1. Install a fresh prod systemThis option requires applying all patches (as you mentioned above) plus you will have to convert to ASM/RAC on the source/target instance. I would not recommend this approach since would require extra work/time.
2. Convert source system to ASM + RAC before cloning to target - setup as below:
(Source)
APPS server - 32bit
DB server (2 node RAC + ASM) - 32bit
(Target)
APPS server - 32bit
DB server (2 node RAC + ASM) - 64bitWhat are the source and target database version?
As per (Certified RAC Scenarios for E-Business Suite Cloning [ID 783188.1]) this is supported by Rapid Clone. So, in this case you need to convert the source instance to RAC and migrate to ASM then use Rapid Clone to clone the application/database.
Cloning Oracle Applications Release 11i with Rapid Clone [ID 230672.1] -- 6. Cloning a RAC System
You will have to convert the target database then from 32-bit to 64-bit.
3. Clone existing target system (non RAC and non ASM)
copy source APPL directories to target
Install 64 bit Oracle 10g to the target system
clone/convert database source (9i 32bit) to database targer (10g 64 bit) using RMAN.
Install clusterware 11gR2
Convert database to RAC Here you will have to convert to RAC/ASM on both the source/target instances -- You are eliminating the patches part in Option 1, but again extra work need to be done to convert the database from 32-bit to 64-bit on the target instance + convert to RAC and migrate to ASM (on both instances).
Based on the above, I would recommend and suggest you go with Option 2.
Thanks,
Hussein

Encoding configuration for signed and encrypted emails

I have a 8820 device (no BES server) - I have certificates downloaded and trust on the device. I can attach the requisite certificates to the message, but I do not have the option to select signing or encrypting encoding. the menu does not give me this option. I have the S/MIME package installed. Any thoughts / pointers?

The S/MIME support package is only supported with a BES. You might try Djigzo for BlackBerry. Djigzo for BlackBerry is an add-on to the Djigzo Email Encryption Gateway which can be used to send and receive S/MIME digitally signed and encrypted email from a BlackBerry smartphone. An installation of the Djigzo gateway is required.
Djigzo for BlackBerry and the Djigzo gateway is open source and can be freely used.
For more information see www.djigzo.com

TNSNAMES.ora for DR And Primary Instance

I have 2 node rac, how do i specify load balance and failover in the client tnsnames.ora including DR hostnames so that when the primary instance is not available it automatically goes to DR. Instead of flipping the tnsnames.ora.

You seem to have a substantial amount of confusion in your request.
When you use the term DR are you referring to an unmentioned Physical Data Guard implementation somewhere else or are you misusing the term to mean "the other node in my cluster?"
In what version of Oracle?
What services have you defined?
How is failover configured? Using TAF or FCF?
You need to provide a lot more information for us to help you.
Load balancing has nothing to do with failover. Are you asking about one of them or both?
Review the capabilities of the DBMS_SERVICE package with respect to creating a service. How did you define your RAC services?

Data Guard configuration for RAC database disappeared from Grid control

Primary Database Environment - Three node cluster
RAC Database 10.2.0.1.0

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
Maintenance tab
Setup and Manage Data Guard
Logged in as sys
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.

Hostname configurations for rac install

Is there any note which shows restrictions /recommendations for hostname configuration outlined by oracle to install a 2 node cluster with SCAN features enabled.
with any Oracle applications that would reference this Oracle RAC server ?
The applications of most concern are Oracle GRID,SQL*NET, ODBC,SIEBEL UCM,SIEBEL CRM

Simply comply to RFC 952 and use FQDN.
For hostname resolution, you need to use DNS (preferably), but +/etc/hosts+ can also be used (works fine, but not recommended for robustness).
