Downgrade Oracle Database 10g Release 10.2.0.2.0 To 10.2.0.1.0?
Nov 29, 2011
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
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..
We are using the following statement to obtain a row lock in a table in the database(ORACLE 10G), SELECT * FROM {TABLE_NAME} WHERE ID = 1 for update and if we succeed grabbing the row lock we will continue to issue a update statement every 30 seconds to preserve the lock as far as possible. here is the update statement to preserve the lock,
UPDATE {TABLE_NAME} SET time = ? WHERE ID = 1.
As you see more longer we keep holding the row lock , more update statements are submitted in the pending transaction. In normal case our application can grab the exclusive row lock and works for a long time,however sometimes a connection reset exception is thrown and our application will close the connection(I assume the pending transaction will be rolled back by the database) and exit the JVM. Since other applications will keep trying to grab the same row lock to become the master role, we expect one of them can succeed but they are all failed because the database has not released the row lock as expected. how and when the row lock can get released in our use case?
I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,create public database link using 'orcl';then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.
we need to find the key pressed action and key release action on Oracle form 10g. On key pressed (i.e. key-up, key-down, key-page-up and key- page-down) the event will be fired and as soon as the user release the key, the event will be stop.
As current situation, we have one form which contains the database blocks. As per search condition, all the data populated in Database block, there are 1000 and more records. Now user going use any of key (i.e. key-up, key-down, key-page-up and key-page-down) as he pressed key ( say Key- down) it scrolled down but as soon as he release the key, the event is not stopped. its going on going down then stop.
Is it possible, as user release the key scrolling will stopped at same time ?
I want to upgrade all the Oracle 10g Release (10.2.0)master sites (bi-directional) databases to Oracle 11g Release (latest). In fact, we are using bi-directional oracle streams and snapshot replication, it means capture,propagate and apply process is running.
why we seem to be unable to report against the ap invoice hold release date using Discoverer in Oracle 11.5.10? the person who wrote our current report used a decode statement to look at the last update date of the release lookup code to create a release date, but i am trying to recreate this in a different tool (Qlikview) and just wanted to understand why we seem to be unable to report on the field as is!
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.

We have Forms application created in Oracle Forms Builder version 9.0.4.0.19. We have done modification in some forms and few forms created using Oracle Forms Builder 10g version 10.1.2.0.2.
Now we need to convert those forms which are around 5 or 6 in number to Oracle Forms 9.

assuption is that when we truncate the partition it immediatly release the allocatd storage.i have just tested the scenario , but still i can see that table size is same even after truncating the partition( which have around 25% of the data)
alter table test truncate partition t1p3 update indexes ;
OR
alter table test truncate partition t1p3 drop storage update indexes ; to see the table size:

Share 11g Release 2 Grid infrastructure and RAC installation experience on Sun SPARC. Any documentation which provide complete information from server setup to database setup.
Ours is Oracle 11.2.0.2.0 Db 4 instances RAC on Unix AIX OS.Since long we are facing problem that CPU utilization reached 100% and reboot is required alteast once or twice a month.On seeing the Events Logs we find that the Event "CURSOR PIN S WAIT FOR X" is consuming a lot of waits.
On analyzing i came to know that we are firing same query from Application 15 to 20 lack times for which a lot of Mutex keeps spining for getting Shared Mode and consumes a large amount of CPU.
I am new to this forum. I want to install XE 11g Release 2 in windows 7 64 bit. Can I intall 'Oracle Database Express Edition 11g Release 2 for Windows x32' or is there is 64bit version?

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
