RAC For Separate Node's Physical Location
Mar 21, 2012
I would like to implement Oracle RAC with 2 nodes for SE Licence. I did a lot when both this nodes with 3 NICs each were plugged at the same switch. Now I have a need to construct a RAC when two nodes will be in separate locations, abot 4 miles from each one. What should I explain to our network administrator he needs to do to implement this solution? I've been told that they can do a FO channel to each location. But don't have exact clear explicaton.

I have 2 databases. Primary ( DB1 ) and Standby ( STBY1 ). My standby database went kaput, and i have as a result deleted the standby database in order to re-create it from a full primary backup.
Oracle 10g R2 on Server 2003.
I have followed several guides, and at this time i have done the following:
- Configured standby re-do logs on primary
- backed up current controlfile for standby
- backed up database plus archivelog
- configured the tnsnames
[code].........
The problem is here. I connect to RMAN from standby
rman nocatalog
connect target sys/password@ DB1
connect auxiliary /
run{
set until scn xxx;
duplicate target database for standby dorecover;
}
I receive an error message saying that it cannot find the file location of the backups that its trying to find. I see in the error that it tries to look locally for
E:FLASH_RECOVERY_AREA DB1 BACKUPSET2013_02_12), however the actual location is (E:FLASH_RECOVERY_AREA STBY1 BACKUPSET2013_02_12)
I have read that the locations need to be the same, however the instance names are different, and i thought i changed the pfile to accommodate that. My assumption is that i have made an error in the pfile. However i cannot see any issues there. Some things that i have changed in the pfile for standby:
*.db_file_name_convert='DB1','STBY1'
*.db_name='DB1'
*.db_recovery_file_dest='E:FLASH_RECOVERY_AREA'
*.db_unique_name='STBY1'

Normally if node fails, VIP & resources are transferred to another node (clients need to failover).
if node is back again CRS detect this, make it as 'family member' and try transfer VIP & resources back to this node (clients will force to failover again).
this failover (despite of failover method I use) make each uncommitted transaction to be rolled back. client need to be disconnected from the service and VIP through they are connected to this service and they need reconnect to the new node - during this stage all DMLs modifications are gone, and need to be re execute.

We have taken export expdp backup from prod database (primary database- Data Guard).
1.) Import impdp is very slow 10GB/Hrs on staging database (Data Guard MAXIMUM AVAILBILITY)Since Server configuration, database version and configuration, operating system everything are same as production. No blocking, locking or waiting sessions
2.)import impdp is fast 90GB/Hrs on Test standalone database and this test database is running in NOARCHIVE LOG mode with oracle standard version after that no more difference.
CPU,Memory,network and disk I/O are look normal while importing on both databases.why that much difference on import.

current environment
Oracle VM 2 Node RAC cluster
Oracle 11G 11.2.0.3.0
Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5
152.144.199.171 vmorarac1.pbi.global.pvt vmorarac1
192.168.2.30 vmorarac1-priv.pbi.global.pvt vmorarac1-priv
152.144.199.184 vmorarac1-vip.pbi.global.pvt vmorarac1-vip
[Code]....
Query is is that all ok to reboot the new node to reflect changes as below and change the hostname to vmorarac2
152.144.199.210 vmorarac2.pbi.global.pvt vmorarac2
192.168.2.32 vmorarac2-priv.pbi.global.pvt vmorarac2-priv
152.144.199.211 vmorarac2-vip.pbi.global.pvt vmorarac2-vip
hostname change in /etc/sysconfig/network
On new node vmorarac5, there is alreay software for RAC DB and GUI cloned from vmorarac1
addnode.sh is used to add existing node, but as part of pre-requisite configuratoin is there any config step missing

I believe, in a multiple RAC Physical Standby nodes only one node applies the archivelogs to the standby database. How you can find which node is the APPLY NODE using a SQL query?
I know you can veiw this information by querying the standby configuration using DGMGRL but how would you find out this information from a remote client using SQLPlus/PLSQL?

I am installing Oracle 10g Clusterware in RHEL 5 Server. When i run root.sh in the second node the last step Running vipca(silent) for configuring nodeapps failed. Then i run VIPCA manually in second node and configured vip configuration successfully,but when i checked the post-checks for cluster services the Checking existence of VIP node application,Checking existence of ONS node application and Checking existence of GSD node application in second node failed. I am able to ping both the servers one another with vip name successfully and the CSS,CRS and EVM appears healthy in both nodes. 1. Does the vip configuration is proper? If no what is causing this error and how to rectify it? Find the output below

I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ...
2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).

I'm trying to add the third node to my existing two node cluster. In fact i succeded adding the node but i have the following problem:
-when i start node 1 and 2, everything is ok, but on node 3 startup one of the other nodes fails
-this happens in any combination: start 1 and 3, everything is ok. when i start node 2, node 3 fails
The asm configuration (disks, permissions, etc) is the same on all three nodes.find below the asm and crsd log details from the failure time:

I can separate numbers from string (info) and the first value of the string using REGEXP_SUBSTR (see below):

REGEXP_SUBSTR ( info, '[[:alpha:]]+',1) brand
from dat
But how can I get rest of the values from that string (red color) ?
I just would like to get separately like:

create table nov06(
f_name varchar2(20),
l_name varchar2(50),
m_name varchar2(10)
)
insert into nov06 (l_name) values (aaa,bbb);
insert into nov06 (l_name) values (ddd,nnn,jr);
insert into nov06 (l_name) values (fff,mmm);
here the values in the l_name are seperated by ','.
comma seperated values represents "f_name,l_name,m_name".
I've to seperate the strings and put in their respective fields.
Quote:
e.g in second insert statement value (ddd,nnn,jr), so the values will be
f_name -> ddd
l_name -> nnn
m_name -> jr
how can I do it???

This I want TO separate TO different COLUMNS based ON comma.
THE RULE IS LIKE out OF total five fields FIRST 3 comma will be FIRST 3 addresses AND rest will be address4 AND LAST NUMBER should appear IN pincode field IF found.
The trouble is for reading reverse to get the number.
WITH address AS (SELECT 'Avenue Supermarts Pvt Ltd,Anjaneya, Opp Hiranandani Foundation School, Powai, Mumbai,Pin Code 400076' addr1 FROM dual UNION ALL
SELECT 'Plot No. J-I, Block B-I, Mohan Co-operative Industrial Area, Mathura Road, New Delhi-110044' addr1 FROM dual UNION ALL
SELECT 'Padmashree Arcade, NH 5, Chinagantiyda Main Road, Gajuwaka, Vishakhapatnam' addr1 FROM dual UNION ALL
SELECT 'The Icon, 2nd 3rd Floor, #8, 80 Feet Road, HAL III Stage, Indiranagar, Banglore-560075' addr1 FROM dual UNION ALL
SELECT '13/1, International Airport Road, Bettahalasur Post, Bengaluru-562157' addr1 FROM dual)

Let's say I have this table:
create table TEST
(
CF VARCHAR2(16),
START_DATE DATE,
END_DATE DATE
)
with
insert into test (CF, START_DATE, END_DATE)
values ('ME', to_date('01-01-2011', 'dd-mm-yyyy'), to_date('31-12-2010', 'dd-mm-yyyy'));
I need make a select where I get n rows, where n is the number of trimesters that compose the date interval in the table. Each of the returned rows must have as start_date/end_date the boundaries of that trimester.(ALL start dates are the first day of a month, and all end dates are the last day of a month)
In this case I need to get:
ME - 01/01/2010 - 31/03/2010
ME - 01/04/2010 - 30/06/2010
ME - 01/07/2010 - 30/09/2010
ME - 01/10/2010 - 31/12/2010

We are using oracle forms 10g, in formsweb.cfg file i gave separeteFrame=true and it works fine also like IE & applet window is opening. But User wants to hide the IE in backegroud and they want only applet window, so using VBScript we are hiding the IE and now only applet window apears this also fine.
I am running the report and displaying the report using web.show_document, report is running fine and displaying in IE with PDF format. But the problem is if i press the run report button report is opening and displaying behind the applet window not infront of applet window and there is no focus on the report IE also. How to display the report output(IE with PDF format) infront of the applet window and current focus on the report window(IE with PDF).
Note: If i use separateFrame=false then report is displaying infront of the IE screen and focus is on the report IE.

I am simply trying to execute a couple of select statements in a single dynamic query. I also want it to return a seperate result set from each statement (something quite easy in T-SQL - but seemingly impossible in PL-SQL!)
This query is being run from C#, but i also get the same results from Sql Developer.This is what i'm trying to execute:
begin
select * from studies;
select * from studyprogressions;
end;
The error i get is "an INTO clause is expected in this SELECT statement" for each of the select lines - As you may already have worked out - I don't use Oracle very often and am starting to feel very stupid considering i have certifications in SQL Server/T-SQL!
I have searched online for a solution, but it seems that everyone with the same error is trying to do so much more.Why is nothing in Oracle simple? Give me SQL Server any day of the week.

As we know that date datatype can store both date part and time part. If I specify the Date format for my database as 'DD-MM-YYYY HH@$:MI:SS' can i ensure i anyways for a particular columns in the database containing date values the format is 'DD-MM-YYYY' i.e without the time part.Can we specify seperate date formats for specific columsn in database during table creation?
