we are moving datacenter from one place to another where existing datacenter has got ASM(RAC env) with HP storage which needs to be moved into target datacenter for EMC storage.basically How ASM can be disassociate from source HP storage then associate target EMC storage with very minimal down time.
what are all the ways and all step by steps required for the same.
We have a 10.2.0.4 database running on HPUX platform which uses EMC for it's storage. We want to migrate the database to an AIX server. Is it possible to just clone the luns where the datafiles live using the EMC utilities and then bring up a database on the AIX server since both platform use big endian for the files?
View 2 Replies View RelatedMy organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?

I want to change the table storage without disturbing the application development just the xml type column into Object relational and merged all the 4xml schemas into master schema.
Right now i want to insert the data from old tables which had different URL . How I can improve performance without having 20Gb on secondary index objects.
In one of the book (Personal Oracle Real Application Clusters: Create Oracle 10g Grid Computing) I have seen the detailed explanation to configure Oracle 10g RAC on external disk- MAXTOR A01A200.
Is it possible to configure Oracle 11g Release 2 RAC with two node using MAXTOR disk?
or Is there any other external disk available which I can use it as a shared storage?
I need a 2-3 TB storage server group for Oracle Database. We want SAN Storage & Server for Oracle Replication, but not Microsoft Storage Server.
For example : HP DL380 G6 as a server and EMC CLariion CX4 120 as a SAN Storage etc...
We have an option, but want some others. What do you recommend for a Server & for SAN Storage (Make & Model) to use for Oracle Replication?
I wanted to setup a two node 11g RAC with ASM at my home for learning purpose. I have read many documents to configure shared storage using NFS, Openfiler, VMsetup etc. Is there any hardware available (something like maxtor disk) which is not much expensive to setup a shared storage ?

View 1 Replies View RelatedOur Application is on Oracle 10g and we are going to migrate to Oracle 11g.
1) As of now we are using ojdbc14.jar. So if we migrate can we use the same jar or is it mandatory with 11g to use either ojdbc5.jar or ojdbc6.jar. I guess these jar version depends on the version of jdk we are using. But we are using jdk1.5 and still we use ojdbc14.jar which is working fine. So is it like , Oracle 11g can support only jdk1.5 or jdk1.6 ?
2) Is there any effect on the coding part if we change ojdbc14.jar to ojdbc6.jar ?I have seen there are some extra classes used in ojdbc6.jar.
3) Also we are going to migrate the Oracle database from Solaris to AIX. Our application lies on Solaris.So is there any compatibility problem , if our application lies on Solaris and database on AIX ?

Is the oracle migration assistant a utility with the oracle forms 6i distribution? Or do I need to download it from somewhere else? Is there a license required? Is there a disadvantage of using Oracle Application Express for the migration from oracle forms 6i to 11g.

a) I run a report works fine
b) Now I goto any other master screen and just query some data
c) Now I want to run any of the reports, nothing works..
To generate the report I have to open another instance of application then I can run the report... In this instance again same story repeats... I dont know what is the problem...

We have to perform migration for our RAC database to new SAN that is at new data centre. Since OS is IBM AIX, we can take backup from mksysb for VG and and storage will migrate data from OLD SAN to NEW SAN.
But even we restore VG and SAN data but since our old SAN is emc and new SAN is hitachi, so disk path for all the asm disk group will be changed.
So is there will be any way to rename this disk path for disk group..
We have our current production running on 9i and eventually want to migrate to 11g-r2. But the challenges are as follows:
9i production is running in San Francisco data center. 11g-r2 Production already setup up and running in Atlanta data center.
The database size is around 2 TB running on 9i. We are looking to transfer this to 11g-r2 and wondering, what options we have at our disposal: I was looking into EXP/IMP, but somebody said, dblinks will be much faster and reliable than EXP/IMP.
Currently our application running with Database - oracle 10.2 and front-end SAP11.5. We are going to upgrade our database (oracle 10.2) to 11g (version not sure) and upgrading application from SAP 11.5 to 12.2. As part of it i want to know what are all things i want to take care while migration (oracle upgradation) as I'm oracle developer.
1) Is it possible to access objects in 8i database from 11g database using DB link?. (as like 10g to 8i).
2) Is it possible to access objects in DB2 database from 11g database using DB link?. (as like 10g to DB2).
I am converting an application initially written in Forms 4.5 to Forms 10g. Currently I am facing 2 issues regarding the change in functionality from 4.5 to 10g.
There are 5 items in a block and the WHEN-NEW-FORM-INSTANCE trigger sets one of the items (the third item ITEM3) programmatically to display only and assigns a value to it. There is a WHEN-VALIDATE-ITEM in that item (At that point it doesn't fire and this is OK).
When the user navigates from ITEM1 to ITEM2 and then to ITEM4 (because ITEM3 is disabled) the WHEN-VALIDATE-ITEM of ITEM3 does not fire immediately. In forms 4.5/6i the trigger was firing and a lot of functionality was built on that behavior.
In forms 4.5 it was possible to cancel a long running query (during EXECUTE QUERY) using Control-C. The control C doesn't seem to work in form 10g. Is there any way to force a cancel of a long query in 10g?
my current database version is 10.2.0.3.0 and we are going to migrate our database to 11.2.0.3 .

Some shops run Oracle RAC using "conventional" storage, like emc, netapp, etc. Some shops run Oracle RAC using JBOD, just bunch of disks, all redundancy is managed by ASM.
How would you distinct these two approaches? JBOD approach sounds cheaper, so why serious enterprises are still using traditional conventional storage, like netapp and emc?

DB: Oracle 10g R2
OS: SUSE Linux SP 1 x864
We are maintaining a DR of our Database Server(oracle 10g R2 atop SUSE SP1 Linux) using Platespin(
[URL]......
Platespin is set to replicate(block based), incremental data(delta) every 1.5 hour from Production to DR site over a 30 Mbps dedicated fiber link.
Our maximum changes of data per day(during business hours) wont exceed 300 MB. During business hours Platespin replicates at least 1 GB at every replication cycle, while during off hours it replicates 300 to 500 MB per replication cycle. We are facing this strange issue with this box only(SLES 10 SP1 + Oracle 10g R2), we have protected MS Exchange 2007 Server based workloads without this strange issue, i.e in case of Exchange only delta replicates from Production server to DR site on Platespin.
Platespin support says us that Oracle re-indexes its database for better performance, so it is possible that re-indexing causes the blocks level changes on the storage, and since Platespin works on Block level, thats why it replicates so much(even though data is not changed that much)
here is actual words of Platespin support
<snip>
I think whenever Oracle database Indexing happens, it changes almost most of the Blocks of database and Platespin replicate all those Blocks.
As you know, Platespin checks the Date/Time attribute of every blocks before replication and if Date/Time attribute changes from last replication, it considers as changed block and replicate those blocks on Platespin Appliance. So, my suggestion is just look into the Oracle server behaviour before/after Data indexing process and do needful or do some workaround to overcome this issue.

is there anything we can do at oracle level ?
I am having an issue with the LOBs in our Database. Our production DB is about 71G right now - if i do export/import using the DataPump - I see the data volume becomes 40G. I am sure its because of the LOBs in my Database. Our application uses lots of LOB datatype and I think the space is not being released.
The challenge is I cant do a full export/import in my Production DB as its a 24/7 system and to do export/import I need min. 5 hrs - which my business will not permit. I can I claim the unused space here. I have used Segment Advisor - but it has only given me 6G of space gain.
Is there any script I can try to use to reclaim space in the database.
