Any Way To Downgrade 11.2.0.2 Database
Apr 14, 2011
I am running oracle 11.2.0.2 on AIX 5.3 and when I issue the rman command below to a target DB running 10.2.0.4 I get this error.
$ rman catalog=rman/rman@prod target=sys/sys@prod

Recovery Manager incompatible with TARGET database: RMAN 8.0.4.0 to 10.2.0.4 required

RMAN-00554: initialization of internal recovery manager package failed
RMAN-06429: TARGET database is not compatible with this version of RMAN
What I was trying to do is duplicate my 10.2.0.4 DB and overwrite my 11.2.0.2 DB. Is there a way to downgrade my 11.2.0.2 DB. my 11Gr2 DB I have already set the compatibility parameter to *compatible='11.2.0.2' My 11gr2 is a test DB I don't have a valid backup..

am trying to downgrade my oracle database 10g release 10.2.0.2.0 to 10.2.0.1.0the reason for this is that i had to copy /oracle_home/bin utilities from 10.2.0.1 to 10.2.0.2 because of this most utilities like rman,dbca were not working.
i think i need to downgrade my oracle database 10g release to 10.2.0.1.0 right?i read some oracle documentations of database downgrade instruciting me to
>take full backup of oracle DB
>ORACLE_HOME/bin/emctl stop dbconsole
SQL> STARTUP DOWNGRADE
DROP USER sysman CASCADE;
>SQL> SPOOL downgrade.log

I am running a 10gR2 rac database on 11gR2 grid.
I like to switch from a rac to a standalone database including downgrading the license to standard edition one. Actually SE1 is not an install option for 10g.
Would it be enough to reconfigure the 2nd rac node ?

I have started to migrate 11.2.0.3 database from Enterprise to Standard edition with expdp/impdp (RHEL box). I've managed to transfer database without any problem (ok i had little difficulties with bitmap indexes but never mind).
But now i do not have all public synonyms in place as i already knew. So i have to create sql script and i have found several good ones. My question is do i need to recreate all public synonyms or there is a exceptions in my case because i now have Standard Edition database (old one was Enterprise)?

I am checking out licenses. We all know that EE is much more expensive than SE. But many customers do have EE installed - unsure if they need all the features at all. After several years of production, a downgrade is considered 'risky' and we continue to pay the full EE.
How can we check and be sure that a downgrade to SE would not be any problem?
Some checks include:
* partitioning used in user schemas? --> no downgrade to EE
* bitmap indexes in user schemas? --> no downgrade to EE
How can we complete this list, or is there some script to make this easy?

I want to downgrade my database from Oracle 11g (11.2.0.1.0) to Oracle 9i (9.2.0.1.0).
I've done trial of taking export of higher version(Oracle11g) through lower version(Oracle9i) exp utility and trying to import same exp.dmp files into lower version(Oracle9i), but not succeeded and getting some parameter related error.
On Oracle9i database client- Here i'm connecting to Oracle11g via use of 'wbdata.wbh-db1' service

I wanted to downgrade our 2 node RAC 11.2.0.3 to previous version11.2.0.2 on our test environment, so i could prepare to upgrade production later.
I followed oracle documentation and issued
'/u01/app/11.2.0.3/grid/crs/install/rootcrs.pl -downgrade -oldcrshome /u01/app/11.2.0/grid -version 11.2.0.2.0'
and both nodes and manually removed file in upgraded oracle home (rm -r u01/app/11.2.0.3).
This seems to have caused havoc and ASM and srvctl are no working. lsinvemntory lsinventory still poitns to removed oracle 11.2.0.3
I tried to set
export ORACLE_HOME=$ORACLE_HOME
.oraenv
+ASM1
srvctl config ##n
srvctl config

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

Database Version - 10.2.0.4.0
OS - Red Hat Linux
We have configured oracle one way stream between two databases. Source database is capturing the changes (No downstream configured). Configuration was working fine but destination database was lagging behind very much i.e about 15 days behind the source database. We are ok with this but the problem is now that , as per client request we have restored previous backup and open the database with resetlog option in source database. After resetlog , archivelog sequence has been changed and stream is not working.
Can I apply the previous archivelog (before resetlog archivelogs ) in destination database anyway.Source database is a production database.

Here we have a data guard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. Also we configured one schema on a third machine as catalog database using following steps. The steps executed in catalog database(appsdb):
SQL> create tablespace rmancatlog_tbs datafile '/u01/app/oracle/oradata/NEW/rman_catalog.dbf' size 500M autoextend off extent management local segment space management auto;
SQL> create user rman identified by oracle
2 default tablespace rmancatlog_tbs
3 quota unlimited on rmancatlog_tbs
4 ;SQL> GRANT connect, resource, recovery_catalog_owner TO rman;
RMAN> create catalog;
recovery catalog created
Added tns entries of catalog database in primary and standby. Then from primary database we tried to register to catalog database. It is showing that it is registering. But every query afterwards in rman is throwing the error. Below are the steps and error:

I am part of a upgradation and migration proj where an Oracle 9i db on a HP-UX OS is going to be upgraded and migrated as 10g db on a solaris OS environment.I am from the application team(Data warehouse team) and we are yet to allocate a specific DBA for taking care of this activity.
We are still in the requirements stage...different requirements and challenges that should be taken care and would occur in the roadmap of this project from a DBA perspective.All your inputs would be very valuable to me.

I have CPU based Oracle server license. In this case as per license policies of Oracle I can have unlimited database with unlimited users connecting it.
I need to create as many as 100 database with upto 100 users (max) for each database as client. What is the recommended hardware for this server? CPU/ RAM/Harddisk, recommended chipset on the motherboard (in case of database storage capacity required is not high typically - 20 GB is OK per database - average), redundancy is critical, also Oracle database vault is going to be installed; as security is of prime importance between users of different database. Which specific server models from specific vendors like IBM/ Dell/ HP are good ones for this purpose?

I would like to know about oracle 12c. In 12c, when i read documents,i understood that one container DB(CDB) can contain upto 253 pluggable DB and this pluggable DB(PDB) is similar to our traditional database(pre 12c).
1) whether my existing database (11.2.0.3) can be upgraded as pluggable DB and plugged it in CDB?
2)i read that we can move from local data center model to cloud in this version. Is that mean that once PDB is ready, whether we can plug it in CDB using private cloud or public also possible?
3)If public cloud is possible, are both CDB and PDB accessed through cloud client only?If so, whether our user data that is available under PDB also moved to external place?
