My exadata quarter rack machine has two asm diskgroups, DATA1 with 5TB and RECO with 3TB. I'd like to resize RECO to 1TB and DATA1 to 7TB.
I know ALTER DISKGROUP RESIZE command, but my question is about resize RECO volume from 3 to 1 TB: is it supported by Oracle?? Let me know risks /issues with this resize?
I've been ASM quite a while. I've two diskgroups extdg and nordg which are of external and normal redundancy respectively. Total diskgroup size is 9G, usuable space came down to 3mb when i tried to resize it to itz maximum. the value under usable column shows the same.
FYI... i've totally three disks in nordg, two in one failgroup and one in another.The disk sized equally 3g each.

EXTDG 2047 1995 1995

The command i used to resize all disk to their max is Quote:SQL> alter diskgroup nordg resize all size 3067M;
One of my databases which is running on exadata x2-2 , has been restored to non-exadata machine in order to test few things. I had a sub-partition table in the exadata , compressed for query high. test machine (NOT EXADATA) , after uncompressing this subpartiton tables i am getting the following err message :
ORA-64307: hybrid columnar compression is not supported for tablespaces on this storage type I have executed the following commands :
alter table crm.cm_ncd modify partition P01_CM_NCD nocompress;
alter table crm.cm_ncd modify partition P02_CM_NCD nocompress;
alter table crm.cm_ncd modify partition P03_CM_NCD nocompress;
[code]...
ERROR at line 1:
ORA-12801: error signaled in parallel query server P005
ORA-64307: hybrid columnar compression is not supported for tablespaces on this storage type If all the partitions are uncompressed why i am getting this error message ?
This is the below method which I have used to figure out exadata model.
ex: grep -i MACHINETYPES /opt/oracle.SupportTools/onecommand/databasemachine.xml <MACHINETYPES>X3-2 Half Rack HP</MACHINETYPES>
But for one environment, though it is a full rack but still I am getting result as half rack.
I am having an Oracle 11g R2 RAC setup. My database size is 22TB in normal servers. I have checked my database in Exadata X2-2 and found out that the HCC was good and as per my assumption the 22TB can come down to 10TB .
My challenge is i need to transfer the 22TB data to the exadata quater rack which is having space constraint. Is there any way other than export & Import as data export and import will use entire 22TB. Is there any way to transfer the data to Exadata with compressed form from the source server.
I am having doubt on the no_index concept in oracle. I am using oracle exadata server.It is basically data warehouse project.I am in the situation to join some tables and get the result set for reporting purpose.
Among the tables, 2 tables having huge count.1st table has more than - 1,000,000,000 rows2nd table has more than - 200,000,000 rows when i join these 2 tables with some small set of tables, it is taking long time (around 20 MIN) to retrieve the result set. The final result set is around 100 rows only.
But, when i force NO_INDEX hint in the same query, is giving the same result in very fast manner(around 5 MIN). Because it is working based on cell smart scan. So, can i force the NO_INDEX hint to all tables? I forced the NO_INDEX hint only the table which is contain 200,000,000 rows not for others.
Query Plan : Normal Query using the the range scan based on the key. No_INDEX Query going full table scan.
I would like to know if I can create one OS user by ORACLE_HOME database ?

1) Post Installation check list ie: How can I see every things are installed correctly.
2) upgrade the exadata OS version .
3) Upgrade the Database.
4) Test Migration from Oracle database to Exadata.
5) Right now there RAC servers are installed without domain, I need to add domain name to existing RAC.

I want to re-size redo log group on my production database .i have 10 redo log groups of 50mb each having 2 members.i want 4 redo groups to be of 250 mb each having 2 members and then i will drop that old 10 redo log group(50 mb ) , so that i will have only 4 redo log group of 250MB each having 2 members.But i have physical standby and logical standby configured on production database .

I have a "prj_tbl" named tablespace in a user's schema in my database. i have given 100mb size to the "prj_tbl" at the time of its creation and auto extend is open for 10mb,and now this tablespace is using nearly 3.6mb space for its data and remaining space is free,now i want to reduce the size of "prj_tbl" tablespace to 20mb and when i tried to resize it then ,
It throws an error- "'ora-03297 file contains used data beyond requested resize value oracle"
I think this message showing that my new size is small than the size of data on my tablespace but it shows free space nearly 96mb then it means my new size is larger than the size of data on tablespace. How should I reduce the size..
Today i am facing an error when going to rezise the datafile its fixed size is 19000M abut after truncating all tables it is 112M, but when i am going to resize its datafile to 500M its get me an error ora-03297 file contain used data beyond requested size values.
I have done the same before a week without any error.But this time i got the error

I have a small problem resizing an ASM disk group . I've had a lun with size 50G and added on it an asm disk called LUN1D1. Then I have created a DISK GROUP called data1 (external) witch contain LUN1D1. DATA1 was then made asm volume. So I have an asm volume with size 50G and I need it to be 100G.
Now I have increased the size of the lun with 50G (100G in total). I have rescanned the LUN and os see the new size. The problem is I can not re size DISK GROUP data1 or disk LUN1D1.

I'm trying to increase the size of my system tablespace. The tablespace contains one datafile size 900MB and it can increase to 2GB.
I'd like to change this to autoextend as I'm going to run csscan on the database.
When I do change the autoextend and unlimited part of the file I get: ORA-03297: file contains used data beyond requested RESIZE value
I've also tried to increase the datafile to 4GB but still the same. I can see that there is more then enough space on the filesystem.

A am new in RAC configuration.I configuring RAC with ASM diskgroup with the external redundency. So now i am facing problem to mount the ASM diskgroup. I am giving the the RAC configuration description below.
1. using two node rac1 and rac2
2. asm disk configuration 3 drive
/dev/raw/raw1
/dev/raw/raw2
/dev/raw/raw3
on both node
3. and i am using vmware to configure the both node asmdisk group
after configuring the os level and oracle clustring , i run dbca to configure asm disk group..so in the create disk screen i have found my previous create 3 disks
/dev/raw/raw1
/dev/raw/raw2
/dev/raw/raw3
so first two disks
/dev/raw/raw1
/dev/raw/raw2
i named it "dg1" then press ok , when i pressed ok a warring is appear that is "could not mount the diskgroup on remote node on rac2 using the connection service rac2:1521:+ASM2. Ensure that the listener is running on this node and the asm instance is registred to the listener. Receive the following error:
ORA-15032 : not all alterations performed
ORA-15063 : ASM discovered insufficient number of disk for diskgroup "DG1"
as the same way i create another diskgroup "fg" for flash recovery area using disk /dev/raw/raw3
so after creating the two diskgroup i saw the two diskgroup is appere in the "diskgroup appere screen" an saw that only one diskgroup is mounted but not second node i.e. rac2 diskgroup is not mounted . What should i do no .
Resize or add disk in ASM.
- The storage has partitions like:
- And now, the size of ASM disk was full
Because I've not ever done for adding disk to diskgroup.
Step 1- Format the storage, add partitions (I will create 4 partitions of 120gb, 1 partitions 60gb, 1 partitions 27gb).
Step 2- Add the rawdevice in /etc/sysconfig/rawdevices.In the picture here, I'll not just add rawdevice in /etc/sysconfig/rawdevices. So I'll do:
add lines in /etc/sysconfig/rawdevices
/dev/raw/raw7 /dev/cciss/c0d1p9
/dev/raw/raw8 /dev/cciss/c0d1p10
/dev/raw/raw9 /dev/cciss/c0d1p11
/dev/raw/raw10 /dev/cciss/c0d1p12
[code]....
how to do continue after step 5.
I have one generic question about space management. I have one table with size of 1TB. This table stored in ORC1 tablespace. This tablespace contains 70 datafiles.
Since it's 10.2.0.4 database. I have dropped this table by using purge
drop table <<table_name>> purge;
Once table drop was completed. When I check the tablespace space it was 100% free but due to HWM was unable to resize the datafile from current size to small size. What was the reason behind this. Is there any process needs to follow when dropping big tables ? like instead of dropping the tables do I need to truncate first & then drop .
I need to modify an existing form, thus I have to resize a canvas and a window for it. In windows, I run it and I got the right display. When I transfer it to dev server running in linux, then I compile and run it, it display the previous/unmodified size. I'm sure my form is the one that running, I placed some text there and it was displayed.

There is a disk group named +FRA which has only 1 disk (call it disk 0 for later references).
+FRA disk group is in type of EXTERNAL redundancy
I'd like to add another disk to +FRA disk group and copy all files stored in disk 0 to the new disk (call it disk 1 for ex.), then take off disk 0 (not use for +FRA disk group any more).
Expected result: there is only one disk 1 left in the +FRA disk group, with all the data from disk 0 and keep their original file names

One of the Hitachi support guy has suggested to create a separate disk group for Online redo logs. His rationale was that ORLs was write only files and it would be better to put in a separate disk group.
What is correct way to move the default oracle spfile to ASM diskgroup so i can successfully bring up the instance . After bring up the instance , it should point to ASM diskgroup. My oracle database 11.2.0.3 is siting on sun solaris 64 Bit.

View 1 Replies View RelatedI added a new disk to a diskgroup. It starts to rebalance. However, I plan to drop the diskgroup anyhow and recreate it since I want to restore a database to it.(I shouldn't have added the new disk beforehand, my mistake) So now it's rebalancing and may take some hours.Can I drop the diskgroup now?I think there is no way to stop the rebalance?
