i have 80 gb table d9040 which residing in separate tablespace in existing database(10g) OLTP .
i m going to import(impdp) an export(expdp) dump on 11r2 on which ASM is residing.
I have following two options available while importing
1.Put all the datafiles of that particular tabesace on a single disk .
or
2.Put half datafiles on disk 1 and remaining half on disk 2.
i try to install oracle grid infrastructure 11r2 on cent OS 4.8 on vmware workstation 8.0.2..ASM disk is not showing ,i had also change disk discovery path to 'ORCL:*'i had already configure ASM disk using /etc/init.d/oracleasm createdisk...successfully..
View 8 Replies View RelatedI am trying to drop 90 columns from a big partitioned table. I was trying a physical drop first and since it is taking longer time I decided make the columns unused state and drop them. However I was able to set them to unused state.
Now I am trying to drop those unused columns from the table, it is running since 22hours Apporox. I am keep increasing the undo tablespace to retain the undo data.
I also have decreased the undo_retention to 300 from 900.
My question is there any better way to drop these columns. And is there any way to flush out the data from undo.
how we can perform the tablespace management? monitor the tablespace and tune the tablespace space.

I want to import my dump file to newly created tablespace ,so how can i do that . I have created new user called cvm and while creating it i mentioned default tablespace to newly created tablespace . But when i try to import my dumo file it goes to users tablespace .
i have a tablespace which contains 121 datafile(max limit reached) as a dba what we have to do?
creating a new tablespace with a datafile and assign the users to the current tablespace which i created now.iif the above process is correct,after some time the tablespace which was filled up got freed up.now can i give the access to the users previous (i.e. freed up tablespace) and current tablespaces

My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
I have one database which is recently upgraded from oracle 8.1.5 to oracle 10.2.0.4.The database is having around 300 tablespace and total size of the database is 1.5 TB.
The database was created in oracle 8i and all the teblespace were DMT(Dictionary Managed Tablespace) .Usually after up gradation all the tablespace are in DMT mode. Now my requirement is to convert all the tablespace into LMT (Locally Managed Tablespace) so that I can AVAIL ALL THE FEATURES OF LMT.
This database is a mission critical database and very less downtime can be allowed.
I'm in the process of making a list of changes. What database application changes would be classified as standard changes and would not require a CAB meeting and which ones would be deemed critical that a CAB meeting would be required before going ahead with the change.

View 2 Replies View RelatedI have a quick question about Automatic Memory Management in 11g. I know that it combines the SGA and PGA components together, but the pga_aggregate_target (in 10g) was a target, rather than a strict limit. In certain circumstances you could (and we have) exceed the pga_ aggregate_ target by quite some way.
If I use AMM, does this enforce a limit on the PGA usage – or if I through enough bind variables at it, can I still exceed the ‘target’?
I just wanted to know if removing access for management and tuning packs in OEM disbale its access in just enterprise manager or in the database as well, i mean would that disable access to the scripts in the rdbms.admin driectory as well.

Question1. From googling , I gather that ASSM ( Automatic Segment Space Management ) is a new method used by Oracle to manage space inside data block. If this is the case, then it should have been named 'Automatic Block Space management' . Right ?
Question2.What was the most notable advantage in your opinion in using ASSM as opposed Manual Segment space management ?
what is difference between san and asm because san also provide mirroring like asm,why we should go for asm.

We have a 2 node rac cluster running on HPUX Itanium platform running oracle rdbms 10.2.0.4 that is currently configured using raw devices for ocr, voting disk, and all of the datafiles. We have a business requirement that is mandating that we have to use TDE tablespace encryption and in order to do so we must now upgrade to 11g.We are in the planning stages for the upgrade process and I am just trying to understand or find out what is going to be the best method to move the data that is currently in the tablespaces on the raw devices over to new tablespaces that will be created within ASM and will be created as TDE encrypted tablespaces?Our database is about 1.8 TB and we have alot of fairly large critical transactional tables that support a 24 x 7 oltp environment that cannot afford downtime.

And i see:
Quote:
If MEMORY_TARGET is set to non zero value:
SGA_TARGET, SGA_MAX_SIZE and PGA_AGGREGATE_TARGET are set to 0, 60% of memory mentioned in MEMORY_TARGET is allocated to SGA and rest 40% is kept for PGA.
So, I have set:
alter system set sga_target=0 scope=spfile;
alter system set pga_aggregate_target=0 scope=spfile;
alter system set sga_max_size=0 scope=spfile;
alter system set memory_max_target=512M scope=spfile;
alter system set memory_target=300M scope=spfile;
, and then bounced the instance.
After startup, I see:
SQL> startup
ORACLE instance started.
Total System Global Area 272027648 bytes
Fixed Size 1384012 bytes
Variable Size 100663732 bytes
Database Buffers 163577856 bytes
Redo Buffers 6402048 bytes
Database mounted.
Database opened.

But Total System Global Area should't be in that case 60% of memory mentioned in MEMORY_TARGET? Memory mentioned in MEMORY_TARGET was 300M, and 60% of 300M is 180M, which is not 272027648 bytes.

If the ASM Re balance occur automatically. What events can cause the ASM Re balance to be triggered?
I understand, we can manually re balance the disks in a disk group. I would like to know when this will happen automatically.
We are trying to increase ASM disk space and with respect to it when we are trying to allocate more space this question came across my mind. Now this was previously configured by my previous SA.
[root@oracledbtest1 ~]# /etc/init.d/oracleasm querydisk -d `/etc/init.d/oracl
cut -f2,10,11 -d" " | perl -pe 's/"(.*)".*[(.*), *(.*)]/$1 $2 $3/g;' |

v_device=`ls -la /dev | grep " $v_minor, *$v_major " | awk '{print $10}'`
echo "ASM disk $v_asmdisk based on /dev/$v_device [$v_minor, $v_major]"
[code]....
why are my LUN's showing different sizes on RAC and also the best way to allocate the space to the disks in the above scenario.
I'm using ASM on LUNs from an EMC SAN, fronted by PowerPath. Right now I have only one fiber path to the SAN, so /dev/emcpowera3 maps directly to /dev/sda3, for example. Oracle had a typo in what they told me to do in /etc/sysconfig/oracleasm*, so the scan picks up both devices.
#/etc/init.d/oracleasm querydisk -p ASMVOL_01
Disk "ASMVOL_01" is a valid ASM disk
/dev/emcpowera3: LABEL="ASMVOL_01" TYPE="oracleasm"
/dev/sda3: LABEL="ASMVOL_01" TYPE="oracleasm"
But I don't think it can be using both. How do I see which one it's actually using?
*They said:
ORACLEASM_SCANORDER="emcpower*"
ORACLEASM_SCANEXCLUDE="sd"
But I think that should be "sd*".
We have Oracle ASM and installing 11.1.0.6 on a new machine (eventually will apply 11.1.0.7 patchset). So we are on 11g R1 in production environments.
When installing Oracle ASM 11.1.0.6, the root.sh fails
I checked various metalink notes, all settings are OK. We have ASMLib and i have configured ASMLib with the new disks prior to the ASM installation
Just to rule out the rootcause is with ASMLib , I have also disabled it. Still same problem. I ran the usual localconfig delete and localconfig add too.
