Oracle ASM uninstall issue.

Hello folks. I am using Oracle Database 10.2.0.5
I am having some issues here:
I was told to uninstall a Single instance database that was using a ASM.
I did it using dbca, now i was told to uninstall ASM. But i have a problem, i don't know what's the node's name. How can i check this, once the database was already uninstalled ?
I tried to use crs_start
Thanks in advance.

I did it using dbca, Well, that did not "uninstall" anything, it just deleted a particular database.
now i was told to uninstall ASM. Maybe you should explain exactly what you mean by "uninstall", seeing as your usage of the term in regards to databases is incorrect.
But i have a problem, i don't know what's the node's name. How can i check this, once the database was already uninstalled ?Where are you being asked for the node's name. What node? Is this a RAC setup?

Strange issue in Oracle ASM on Two node RAC where in one ASM node shows all diskgroup while other node shows missing node.

We have Oracle datbase 11gR1 in RAC node with Oracle ASM.Recently our database server got crashed and we are trying to restore back services.
Using Snapshot technologyBusiness copy we had synced all our disk on storage level. Post this when we are trying to start ASM instance on node 1 it is coming and showing all diskgroups but on other node it is throwing errot with missing e diskgroup.
ORA-15032: not all alterations performed
ORA-15040: diskgroup is incomplete
ORA-15042: ASM disk "5" is missing
Expert please share your views.
Thanks,
Tushar

The I/O fabric layer on the other node failed to mount all storage LUNs - resulting in ASM being unable to mount a diskgroup as there are missing disks in that group.
Rebooting is exactly what could be needed to reset the h/w and infrastructure used by that node, in order for it to see all the storage disks again. As node 1 sees all storage disks (and is working), the disk itself on the storage system is intact and usable.
What is the o/s? What is the fabric layer? What is used on o/s for dealing with the I/O fabric layer?

Oracle ASM on top of ZFS volumes

What kind of overhead is involved if we configure Oracle ASM on top of ZFS volumes? Has anyone performed benchmarks using this scheme?

I've not done it personally with DNFS but I have created a multitude of clusters with NetApp on their NFS file system without ever having an issue other than saving a lot of money.

Oracle ASM Disks Question

Hi,
We have two Linux hosts accessing EMC SAN LUNs and we have Oracle ASM Disks created on those devices. Both the Linux Hosts (server1/2)are in once Dell Blade Chassis1 and one of the Server we are planning to move to a different Dell Chassis(2) to have redundency in case of Chassis1 faliure. But if we move one server2 to Chassis2 the HBA WWN Number for the host on the new Dell Chassis2 will change ( WWNs are assigned by Chassis on Dell) and the server2 will loose all the SAN LUNs from EMC Array. I will have to rezone the new server WWNs to storage and pesent the same disks again and rescan the disks which will take couple of reboots. During this period EMC LUNs will not be visible to server2 and I would like to what will happen to ASM disks on the server2 and how to I accomlish this goal? Any detailed steps please? This is a production system with oracle 11g running.
This is the output of emc powerpath devices (LUNs) which is same on both the hosts.
[root@server2 ~]# powermt display dev=all | grep emc
Pseudo name=emcpowerl
Pseudo name=emcpowerj
Pseudo name=emcpowerf
Pseudo name=emcpowerk
Pseudo name=emcpowerg
Pseudo name=emcpowerh
Pseudo name=emcpowerm
Pseudo name=emcpoweri
[root@server2 ~]#
This are the ASM disks on both the hosts:
[root@server2 ~]# oracleasm listdisks
DATA01_F1
DATA01_G1
DATA01_H1
DATA01_I1
FRA01_L1
LOG01_J1
LOG01_K1
[root@server2 ~]#
Thanks in advance.

WWNs are global - not local. If the WWN is foo123 on server1 for EMC LUN1, why would it not also be foo123 on server2 for EMC LUN1? When you move to server3 or install server3, why would EMC LUN1 not have a WWN of foo123 on server3?
I will have to rezone the new server WWNs to storage and pesent the same disks again and rescan the disks which will take couple of reboots. Using Powerpath perhaps - using multipath, not. New devices (LUNs) can be made visible by the kernel my refreshing multipath - no reboot required. If existing LUNs are going to be changed - yes, a single reboot will be needed. But not multiple (unless you have a driver issue with stale connections not being reset on the storage server side).
This is the output of emc powerpath devices (LUNs) which is same on both the hosts.We dropped Powerpath a long time ago. There were compatibility issues between it and AsmLib kernel drivers. Powerpath taints the Linux kernel and limits kernel upgrade flexibility. I refuse to run it on our new clusters. I use multipath instead - the very same s/w used by some of the largest clusters (with Pentabyte storage) in the world. The comfort factor using Open Source drivers (and certified for that kernel version) is significantly higher than installing 3rd party kernel driver binaries - and having to deal with a 2nd party when it comes to o/s and kernel support.

Oracle ASM Configuration on Solaris Cluster - Oracle 11.2.0.3

Hi,
I want some clarifications!
I need to set Active and Passive Cluster settup on Solaris 10 SPARC Operating System, the HA software is Solaris Cluster and Oracle 11.2.0.3.
1) I understand "Single instance Oracle ASM is not supported with Oracle 11g release 2" so we need to go for Clustered ASM - is it required to use RAC framework in this case?
2) When i use the RAC framework, do i need to have license for RAC?
Am new to Oracle, any help is appreciated.

Shashank

Oracle 11g - Date Issue?

Oracle 11g - Date Issue?
=====================
I hope this is the right forum for this issue, if not let me, where to go.
We are using Oracle 11g (11.2.0.1.0) on (Platform : solaris[tm] oe (64-bit)), Sql Developer 3.0.04.
Our NLS_DATE_FORMAT = 'DD-MON-RR'
Using 'RR' in the format forces two-digit years less than or equal to 49 to be interpreted as years in the 21st century (2000–2049), and years 50 and over, as years in the 20th century (1950–1999). Setting the RR format as the default for all two-digit year entries allows you to become year-2000 compliant. For example:
We have a date '01-JUN-31' in our source system. It treat this date as 01-JUN-2031' instead of '01-JUN-1931'. One century forward.
Do we able to resolve using NLS_DATE_FORMAT change?
How do we resolve this issue?
Thanks in helping.

Our source is Oracle data base, where S_date is defined as DATE. Why did you say STRING , when it defined as DATE data type?I doubt you source is an Oracle database. You may have it stored in an Oracle database, but it cam form somewhere else, and was very likely inserted into the table as a string, wherever it came from. Given a string that resembles a date, Oracle will try to convert it to a date using the nls_date_format parameter for the session (which can either be set in the session or inherited form the database). Perhaps this will help explain:
SQL> create table t (conv_type varchar2(10), dt date);
Table created.
SQL> alter session set nls_date_format = 'dd-mon-rr';
Session altered.
SQL> insert into t values ('Implicit', '01-jun-31');
1 row created.
SQL> insert into t values ('Explicit', to_date('01-jun-1931', 'dd-mon-yyyy'));
1 row created.
SQL> commit;
Commit complete.
SQL> select conv_type, to_char(dt, 'dd-mon-yyyy') dt
2 from t;
CONV_TYPE DT
Implicit 01-jun-2031
Explicit 01-jun-1931So, unless you are really inserting dates, not strings that look like dates, you are going to have problems.

Pl-Sql Oracle Function Concurrency Issue

Hi All,
Issue - pl-sql Oracle Function performance issue, when muliple users are accessing the function
Detail -
Oracle 11g / Linux Server
I have developed a pl-sql oracle function to retrieve information from 3 tables, output as a particluar type array.
Single request is getting processed within 2.2 seconds, but when multiple request are sent concurrently <tested with 50>, time taken for each output is different.
BreakUp of Response times:-
8 messages took - 2.2 sec
+8 messages took - 4.4 sec
++8 messages took - 6.6 sec....etc
I'm looking for any DB tunning parameter, which will help to resolve this issue.
My only aim is to expose developed function to multiple users, who all can access it concurrently, but response should limit within 2.2 seconds.
Any thoughts + guidance is higly appreciated.
Thanks
Preetam Singh

ORACLE ASM OR ZFS IN SOLARIS 11

ORACLE DBA EXPERTS
What kind of storage technology is recommended in order to implement an Oracle 11gr2 database in a Solaris 11 OS?
-Oracle ASM or the Solaris 11 ZFS filesystem.
Its any difference between the performance of both storage technologies?
Thanks for answer my questions and i wish to yours a very "Happy Hollydays".
Sincerely,
JOHN JAIRO GOMEZ LAVERDE

From what I understand Oracle recommends ASM. You cannot directly compare ASM with ZFS. ASM is a storage solution providing data management, availability and redundancy specific to Oracle. ZFS is an advanced file system. Whether you choose one over the other will depend on your storage requirements and knowledge.

Oracle ASM disk group

Hi,
Having a multiple Oracle ASM disk group is more beneficial for Oracle database? if no why? if yes why?
Any metalink note if have.
thanks

Any metalink note do you refer?What is your database version?
Please see these docs.

How to Install Oracle ASM 11gR2 In Oracle Linux 6.5

Hi
I want to install oracle ASM in oracle linux 6.5 .
Can any one helps me to find a paper with above subject?
Thanks

Theses steps only if You want to use ISCSI. This is fine to get the howto:
If You ar running in VM Ware Boxes:
Add the following to the *.vmx file for the virtual machine:
disk.EnableUUID = "TRUE"
Restart the vm machine and the /dev/disk/by-id/scsi**** should be visible.
That's a nasty one - without this ISCSI just doesn't work
chkconfig iscsi on
iscsiadm -m discovery -t st -p 192.168.146.100
iscsiadm -m node -T iqn.1991-05.com.microsoft:iscsi-asm-target -p 192.168.146.100 -l
192.168.146.100 <=== IP Number of ISCSI Host
iqn.1991-05.com.microsoft:iscsi-asm-target <== Name of ISCSI Server, you get this as output from discovery command
Now, you must make sure that the devices belong to oracle.
Take a look at this link:
http://www.oracle-base.com/articles/linux/udev-scsi-rules-configuration-in-oracle-linux-5-and-6.php#make_scsi_devices_trusted
Add the following to the "/etc/scsi_id.config" file to configure SCSI devices as trusted. Create the file if it doesn't already exist.
options=-g
/sbin/scsi_id -g -u -s /block/sdc <== for all ISCSI devives
vi /etc/udev/rules.d/99-oracle-asmdevices.rules

Reload:
/sbin/udevcontrol reload_rules
/sbin/start_udev
Now you have your devices read, belonging to oracle:
ls -al /dev/asm*
Next go to oracle download click on list all and get:
Oracle Grid Infrastructure 11g Release 2 (11.2.0.1.0) for Linux x86-64
After extracting this you are ready to go.
When starting the install process you get an option to "change path", here select /dev.
In my test systems I use to set "external" for dataprotection.

Configuring Oracle ASM 11gR2 to use ASMM

Hello,
Kernel hugepages under Oracle Linux is incompatible with Oracle AMM. The Oracle ASM instance under 11g uses AMM by default. So in order to configure Oracle ASM to use ASMM, what are the recommended settings please?
I reviewed http://docs.oracle.com/cd/E18283_01/server.112/e16102/asminst.htm#CHDBBIBF which outlines some information about various pool size parameters required for ASMM, depending on the size of the datafiles that will used.
But what about typical ASMM parametes like sga_target and pga_aggregate_target, or are these not used in an ASM instance?
How have you configred ASMM for Oracle ASM 11gR2?
Thanks!

The minimum MEMORY_TARGET requirment for Oracle ASM is 256 MB. which we have set in ASM.
But what about typical ASMM parametes like sga_target and pga_aggregate_target, or are these not used in an ASM instance? yes ,they will be used ,below snap from aix 6.1 OS

MSSQL 2005 to Oracle Database Conversion Issue

Hi Experts,
We have a requirement where we need to fetch data from MSSQL2005 and store it in Oracle DataBase.
Could you all please let me know which KM module i need to import to achieve it.
Cheers,
Andy

There are a number of options. You should select based on the volume of data and platform, and flexibility of your architecture etc
- At the simplest level, you could use the LKM SQL to Oracle, which will issue a SELECT on the source and do INSERTS on the target (using prepared statements etc, so not horrendous)
- You could use the a bulk loading methodology - by using SQLUNLOAD (or bcp) and then load into Oracle using External Tables or SQLLOADER, which will probably be the fastest solution. (I created a KM which generates all the right code to load the data that way, but without a staging area, you can find it here
If you want a staging area table etc, then you could modify the code in that KM to be an LKM rather than an IKM.

ASM design issue.....

Hi Experts,
We are planning to deploy Oracle RAC 11gR2 on our PROD databases envoirnment. We have 6 databases and the largest database is 140GB of size and rest of the databases are ranging from 15Gb to 90GB. Also we are getting 1TB space from SAN for RAC. Currently used space by Oracle mountpont /u01 is 585Gb and total space is 740GB for exssiting NON-RAC databases.
Need to know how do we design the ASM diskgroups with external redundancy. Goal is to get the best performance from ASM disks.
1) Do we create single diskgroup with 4 LUNs of 200GB size. Also tell us how much size of FRA and VOTING diskgroup should be created.
2) Do we create seperate diskgroup for all the databases. i.e 6 databases 6 diskgroup and each diskgroup with one disk of depending upon the size of the database.
3) Do we create 3 diskgroups with 3 disks in each diskgroup of 100GB. So each diskgroup will be of 300GB.
4) Also need to know if we need to create seperate diskgroups for ARCHIVE,REDOLOGS, like if option 2 is choosen, then create one diskgroup for each databaseas DATA and ARCHIVE and REDOLOG diskgroups for each database as well OR
archive and redologs files will be part of DATA diskgroup.

<li> Configure two disk groups, one for data and the other for the fast recovery area.
<li> A minimum of four LUNs (Oracle ASM disks) of equal size and performance is recommended for each disk group.
About Voting and OCR stored on ASM. I recommend you read this:
http://levipereira.wordpress.com/2012/01/11/explaining-how-to-store-ocr-voting-disks-and-asm-spfile-on-asm-diskgroup-rac-or-rac-extended/
2) Do we create seperate diskgroup for all the databases. i.e 6 databases 6 diskgroup and each diskgroup with one disk of depending upon the size of the database.The I/O operations (performance) is more linked with Storage. However if you have one Array on storage shared by all databases have no sense to create a diskgroup for each database. Because this data on ASM will be separated but on Storage not. Think about I/O concurrence on Storage and not only on ASM.
3) Do we create 3 diskgroups with 3 disks in each diskgroup of 100GB. So each diskgroup will be of 300GB.
4) Also need to know if we need to create seperate diskgroups for ARCHIVE,REDOLOGS, like if option 2 is choosen, then create one diskgroup for each databaseas DATA and ARCHIVE and REDOLOG diskgroups for each database as well OR
archive and redologs files will be part of DATA diskgroup.Do you have area on storage (I mean physical disks) to create one array for each diskgroup? If not forget this, this recommendation is for those wich have possiblity to create different array on storage (using set of phisycal disks dedicated) for each diskgroup.
I recommend you create one Diskgroup to all database and a Diskgroup to FRA.
Each diskgroup should have at least 4 ASM Disk (i.e Lun) with same capacity to maintain balance.
If you can, also I recommend you create one Array for each Diskgroup (FRA and DATA).

Does SAP or Oracle have an issue with these type of processors?

Does SAP or Oracle have an issue with these type of processors?
Intel Xeon X5260 & E5450 vs Intel Itanium PROCESSORS
I want a Sales / Marketing URL link or white papers that talks about processor recommendations.

SAP does neither "recommend" nor "deny" any processors.
If you check http://service.sap.com/benchmarks then you get a lot of machines with different CPUs/operating ssytems and database combinations.
Choose the one that suits best for you.
