Data Guard :: ORA-01102 / Cannot Mount Database In EXCLUSIVE Mode
Apr 28, 2003How i create Standby Database in Same HOST, we using SUN OS 5.8.

Data Guard :: LGWR Sync - Maximum Availability Mode
Mar 10, 2013I have few queries regarding standby database.
1)On primary Database Standby Redo log is required for switchover and on standby database Standby Redo log is required for
--Real time Apply
--Maximum protection or Maximum availability
Am I correct?
2)My database is in Maximum Performance mode. I set up following entry on init.ora:
LOG_ARCHIVE_DEST_2='service=standby LGWR ASYNC'. My question is do I need to have STANDBY Redo log file on standby database in order to use LGWR transport (LGWR ASYNC)mode from primary? Without Standby redo log on standby database can it transport redo data from primary to standby using LGWR transport mode (LGWR ASYNC)?
3)I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode. I would like to know whether is there any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?
Data Guard :: Oracle 9i - Cannot Mount Database In EXCLUSIVE Mode
Jun 30, 2008I'm trying to create a physical standby database on my Oracle9i DB runing on WinXP.
Note: I have both Primary and Standby on the same system.
Actually everything went well .... I did created the standby DB but the problem is I can not start my primary DB if my standby DB is mounted. I get this error:
ORA-01102: cannot mount database in EXCLUSIVE mode
And when I read about the error message I learnt that I should start my DB in compatible mode ...
Data Guard :: Apply Redo While Standby Open In Read Only Mode?
Apr 9, 20131) If i do changes in table on primary database and if i open standby database in Read-Only mode, i can see those changes immediately only if Real Time Apply is enabled. Am i correct? Database version is 10.2.0.4
2) From 11g, It is possible to apply redo while the standby is open in read only mode. prior to 11g, it was not possible. Right?
3) Should I first cancel Managed Recovery prior to issuing “ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY”?

SQL & PL/SQL :: Getting Most Common Value
Mar 31, 2010I am using this query:
Select
t1.col1 as A,
t2.col1 as B,
t3.col1 as C,
t4.col1 as D
[Code]...
with this above query i am getting result like this:
A B C D
2 null 2 null
6 6 null 6
8 null null null
However i need the result like this:
A B C D
6 6 null 6
Note:
I am looking for common value that presents in most of these 4 tables for different t1.col2 values like 'E','G','K',...etc. I cant use the NOT NULL condition in the where clause,since i need to check for different values in t1.col2,for each of this there may be null value in any of the 4 tables.

Data Guard :: Data Change In Metro Cluster
Oct 21, 2012Our organization has recently decided to go for storage metro cluster solution for disaster recovery. In a Data guard environment, we normally calculate how much archive log is generating and based on that value we calculate the required bandwidth.
For storage metro cluster, we need to find how much block is changing in our primary database, and the same rate of change would apply on DR cluster. Now, i need to give the assumption how much changing is happening in my system. How to calculate the change.

SQL & PL/SQL :: Grouping List Of Elements With One Or More Common?
Oct 6, 2011I have a one column table that store lists of elements :
create table test_table (c1 VARCHAR2(4000));
insert into test_table values ('1,23');
insert into test_table values ('1,2');
insert into test_table values ('3,4,5');
[code]...
The output column would be something like that:
output_column
1,2,7,23
6,9,0
3,4,5
I'm grouping columns that have at least one element in common.
(1,23) and (1,2) merge into : (1,2,23)
(1,2,23) and (7,2) merge into : (1,2,7,23) --> Output
(6,9) and (9,0) merge into : (6,9,0) --> Output
(3,4,5) and (5,5) merge into : (3,5,5) --> Output
I have made this logic using only PL/SQL, with loops and nested tables using function memberof, but I suppose that there is a way to improve the performance using only SQL.
