Upgradation And Migration Of 9i Database On HP-UX OS To 10g Database On Solaris Environment
Dec 29, 2010
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.
We have to migrate our database from current OS (AIX 5.3) to Solaris 10. We'll do it through expdp / impdp. Is there any other way to do it as well?
Also, we have dataguard configured at current setup. So is there any way we can take backup of existing database at DR & restore it at new server (Solaris) or we'll have to take a fresh backup from DC (after migration) & ship it to DR & create a new standby?
We have an Oracle 9i (9.2.0.7) two-node RAC database running on Solaris 5.8. Recently we have switched our production database from no archive log mode to archive log. We changed the parameter CLUSTER_DATABASE=FALSE on one of the instances before converting and reverted back.why this parameter needs to be changed to false?
We are planning to migate Oracle database from Linux 10gR2 (non-ASM) to Solaris (ASM) and then Oracle upgrade that database from 10gR2 to 11gR2 on Solaris.
We've been battling with very slow performance for some time. Herewith a detail description of the problem:
Solaris-11/ZFS/Oracle problem
We purchased Oracle T4-2 servers, and are experiencing some weird performance problems.
Hardware: T4-2 2 x 600GB HDD per server 128GB memory per server 2 x dual port QLE2562 FO HBAs IBM V7000 StorWyse data array 2 x CISCO MDS 9148 fibre optic fabric switches Software: Solaris 11.1 MPXIO Solaris 10 branded local zones ORACLE 10g Enterprise edition Project for the oracle user: user.oracle:100::oracle::process.max-file-descriptor=(basic,8192,deny);process.max-stack-size=(priv,32768,deny);project.max-shm-memory=(priv,21474836480,deny)
We received the first server and wanted to migrate our APPB application system and Oracle 10g Standard Edition database from our SUN T5240 to the T4-2.
T4-2 setup � Disk 0: Global zone: Solaris 11.1 ( ZFS - whole disk for the root pool) Local zones: On the Solaris 11 environment we built two branded Solaris 10 zones using an Oracle template provided on the Oracle website - solaris-10u11-sparc.bin.
Our complete database resides on the IBM data array, in UFS LUNs.The UFS LUNs were mounted onto ZFS mount-points in the root partition (/), and then LOFS mounted into the zones.
We started with the Solaris 11.1 environment.
1)After a day or two the performance of the database starts deteriorating rapidly. We then stop the database and reboot the machine. After the reboot the performance level is restored. 2)Another huge deterioration in performance happens when we unmount the V7000 LUNs, and reboot to the alternate Solaris, and re-mount the LUNs. 3)What further compounds the issue is that when we start another the database in the second zone, we see another huge performance degradation. 4)We have logged a call with ORACLE. They requested us to gather information which was analysed by them. They did not find anything wrong with the way ORACLE was installed and the setup of the instances.
On Disk 1 we did a Solaris 10 8/11 (Update 10) installation, which we patched with the April 2013 CPU patchset. In this Solaris 10 global zone we built two native Solaris 10 local zones. The Oracle 10g databases were built in the zones (same configurations settings) not in the global zone, onto UFS LUNs. The database in its entirety lives on the IBM V7000 data array. This works fine.
We then received our next T4-2 server.Loaded it again with Solaris 11.1, and upgraded to ORACLE 12c SE Release 12.1.0.1.0 - 64bit12xxx seeing that Oracle 10 is not certified on Solaris 11. To keep things simple, we built two small databases in the ZFS root pool. The complete system now resides on one disk no UFS LUNs to consider, no Fibre Optic fabric, no CISCO switches, no IBM data array, BUT we get the same problem. The system will run for some time and then slow down drastically. Starting the second database slows the system down abnormally.
We have a RAC in a test environment.It's 2 nodes connecting to an IBM DS3512. The DS3512 has one pool of 8 hard disks (RAID10) which has been then sliced into logical drives:
2 x 1GB then 2 * 400GB
I have been tasked with changing the current configuration as follow:
2 pools of 4HDs in a RAID10 configuration
Then from the first pool: 2 * 1GB 1 * 398GB
from 2nd pool: 1 * 400GB
What I intend to do: 1) shutdown SQL> shutdown immediate; ./srvctl crs stop 2) backup dd if=votingdisk of=voting_disk_backup I already got backups of OCR in $CRS_HOME/cdata/crs/ 3) Perform changes on SAN 4) recreate ocfs2 partitions 5) mount the disks to their folder. 6) recovery recover voting from backup recover ocr from backup 7) Turn service on again ./srvctl crs start SQL> startup;
Would this scenario work. There can be some glitches like the disk names changing after the reconfiguration but I only need to modify fstab for that.
I have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?
Migration from VFP9 to Oracle Database for my personal and microbusiness DBMS.
For a start, having installed Oracle ORACLE win64_11gR2_database (see Attached file) and logged in, how do I create a simple data table and how do I create a front end for the user - a "FORM" to get user input of name, date, bill no etc.,

I am migrating one of my live database from 10g to 11g, which is having its standby database.how can we migrate standby database as well in 11g. do we need to create standby database again or is there any steps?
I wanted to migrate my database from one of the Solaris machine to other solaris(High performance) machine.We are using oracle 9i database.
I wanted to take RMAN backup with oracle 9i database.and wanted to restore that database to other machine and perform recovery.This process will be on production database and requirenement is to reduce downtime.
let me know RMAN backup procedure which will have less downtime of the database.
I have configured data Guard on oracle 11gR2. It is working fine. The only issue i am facing is that when i am stopping the database on the primary server, it is taking a long long time to down the database.
Is it normal?
Furthermore, regarding backup i used veritas Netbackup to perform hotbackup. Can i still used the same principle.
I need to migrate data from Mysql database to Oracle11g database.
a) is there any method available to import the all the sqls like table script,constraint scripts,data(insert ) script from Mysql.so that we can apply the sql directly to the oracle schema after making necessary changes(like datatype).
b) Is there any free tool available for the migration.

I want to migrate our production database from 9.2.0.8.0 to 10.2.0.4.0 through startup migrate ,so request you to kindly provide me a step by step doc or some reference link pertaining with same.
I have one big database which I need to migrate to Oracle, because it rocks with big databases, instead of other databases and when I was made transfer software and all works great except one more think. During this process I found that Oracle normally fill log & undo table, and my question is how to migrate (or can I migrate) database to oracle without filling undo database (deactivate this process) and after that to put database to work normally, because I just need to transfer data as is and from that point Oracle goes on...
I am planning to move the databases in multi master replication from HP-Ux to AIX server. I am planning to use export/import to moving the database. But do I need to drop the replication administrator user before I do export/import?
currently holding 9i database on win2000 and front end is dev4.5 so the thing is want to upgrade by win2008 pn 32bit with 10gdatabase want to keep the front end application as it is 4.5...
will it be compiatble 10g database on 32bit 2008 and front end 4.5developer forms and reports?
can i migrate 9i database to 10g database, what are the steps for full import??
We are in the process of setting up a DR environment for our SAP and Oracle databases . The netapp and our architects came up with solution as follows .
1.Standby databases are built for all production databases. 2.The SAP file systems are replicated to the secondary site 3.The Oracle logfiles and controlfiles are replicated by netapp snap mirror every 10 mins interval 4.The database is recovered through recover standby database every 15 mins at standby site 5.Please note there is no data guard involved . 6.To test the failover , the mirror is broken .The standby controlfile is replaced with Production controlfile and Redo logs files. 7.The standby database issued a startup comnmand and it worked .
Would like to know whether the step 6 is a correct approach ? I tried to convince the architects that this will result in a very disastrous situation for us but none is listened to .
Which is the best method for migration of database from Oracle 9iR2,10gR2 to 11gR2.

i have implemeted grid control for monitoring database. we have different database environment like PROD , STAGE, TEST, BETA.
Now my requirement is, i need to configure PROD & STAGE alert for one group (group1@oracle.com) means, what ever alerts generated by grid should sent notification to group1@oracle.com and TEST AND BETA database alerts should to group2@oracle.com.
Now i am following the oracle manual to configure notifications. unfortunately i could not find to complete my requirement.
