I'd like to get database redundancy with Oracle Standard Edition One. currently have one physical database server and are considering getting a second physical database server.
What's the best way to achieve that without going to Oracle Standard Edition using RAC?
, I have a few doubts in Normal,High and External redundancy levels in ASM concept. External - No failure group. No mirroring. Normal - Two Way Mirroring. One failure group. High - Three Way Mirroring. Two failure group. 1.
above mentioned 3 types in correct.2. My main question is what is the minimum number of disks needed in Disk group creation in Normal and External redundancy??
,Im having following replication scheme: M1,M2 and M3 are multimaster replicated datastores.These three datastores will replicate its data to a node which is going to act as a Propagator.The Propagator will then replicate data to a set of subscribers. Question:-------------
Can we configure the Propagator to be redundant.ie, can we configure an additional propagator which will act as redundant and replicate to the same set of subscribers?
My comp is running with RAC 11gR2 with ASM on external redundancy. we are planning to move on normal redundancy.
which will be better normal redundancy or external redundancy.
One of my collegues created an ASM disk group with normal redundancy using 2 disks. But the disks are not of same size, one disk is 100GB and another one is 10GB. Now the usable space out of diskgroup is showing 55GB. When I checked the diskgroup properties it is showing 2 fail groups one is DATA1_ 0000 with 10GB and other is DATA_0001 with 100GB. My question is why it is showing 55GB as usable space? My assumption is as it is having 2 fail groups with different disks of different sizes. For the failgroup 2 even it is of 100GB size, in order to maintain the redundancy with other small FG(10G) it will consider only 10GB out of 100GB. So, the 2nd FG size also should be 10GB. So that the usable space should show as 10GB as opposed to 55GB (not (100+10)/2).

View 2 Replies View RelatedI Configured an ASM instance and a disk group with two disk for normal redundancy.
> Here .. each disk is 2gb
The disk group has two disks...
SQL> select group_number, name, type, total_mb, free_mb
2 from v$asm_diskgroup;
GROUP_NUMBER NAME TYPE TOTAL_MB FREE_MB
------------ ------------------------------ ------ ---------- ----------
1 DATA NORMAL 4000 3898
as the group has two way mirroring (Normal redundancy) How much data (2 GB or 4 GB) can i keep in the disk group? My conception is I can keep 2 GB data in the disk group... (as the disk group keeps every extent in another disk as mirror)
I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

View 7 Replies View RelatedBut i do a lot of work-arounds to make sure the installation does not make corrupt my OracleAgent,OracleService and OracleDataGatherer. If i just let the installation do its thing i have problems with my libraries, and can't start anything.
The errors are : Procedure entry point 'BlaBla' could not be located in the Dynamic Link library 'AnyName'.
I notice that i have 2 versions of the libraries in OracleHomeBIN (one version 8, one version 11). The programs that start the OracleAgent,Service and DataGatherer call the old libraries but expect to find values that can be found only in new libraries.
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.

While I was trying to configure an Oracle DB called "NW6" using the Database Configuration Assistant, I have Oracle 11.2 database installed on a Windows 2008 Server, the configuration wizard thrown an error : ORA-01507:database not mounted

I have the following question:
I try to duplicate a database on Host B with ORACLE_SID=hostb from an offline full backup plus archive log backup was taken from Host A with ORACLE_SID=hosta. Host A and Host B cannot communicate between them.
I don�t want to make a full restore of database, i want to make a duplicate database from that offline backup.
I need the duplicate database must be run with different ORACLE_SID and different DBID.
PD: I was reading the Oracle Documentation about that but i can�t find a step by step guide to follow.
Environment
Oracle 11gr2 with a Linux OS on x86_64 on host A and host B.
I need download the Oracle 10g to do some migration tests, but isn't not available in oracle website.
