XE :: Uninstall Database And Reinstall It?
Oct 23, 2012
I have a Oracle 11g R2 XE installed in my PC. I also have a licensed VB2010 Ultimate(free from class). I have made three systems using this database, 1 using php and 2 using .net.
My question is, if I uninstalled my database and then reinstall it, will it affect my the systems I made(I already backed-up my tables etc.)?
for example, the components for my oracle-vb connection.Why I need to uninstall? Because I got locked out of the System account:, I can't change my password.

For removing of XML DB I have found: XML DB FAQ. Is it still actual? But I found nothing for uninstalling of VPD and XStreams.

howto to setup an oracle server and "import" my old databases just from the copied directory structure d:\oracle\product\... ("cold backup") to the new install.i was trying to setup an new server by shutting down the db and just copying back my data/control/log/*.ora files which doesnt seem to work.
i could see the old tables structures in the local sqlplus console, but the databases are not reachable over the net.
also the enterprise manager is not able to startup the dbs, it show just an running listener.

I am trying to install 2-node 11gR2 RAC on CentOS 5.6 using VMWare Fusion. I'm in the middle of Grid Infrastructure installation and while choosing the ASM diskgroups I don't see any candidate disks but when I click on all disks i can see them but can't select them.
I tried installing the grid before and ended up with and issue running the root.sh on all the nodes so had to deconfigure the grid binaries using the rootcrs.pl and then deinstalled the grid software using the ./desintall utility.
when tried installing again ...I ran the cluvfy utility ..it doesn't show any errors.

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:
[oracle@db1 ~]$ rman target sys/oracle catalog rman/oracle@appsdb

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?
