ORACLE VM physical CPS vs VCPUs

Hi.
I'm little confused with Oracle VM and how many physical CPU and virtual VCPUs I have.
I'm using ldm list-devices -a to get the information.
Someone could explain to me what the next output means?
Thanks a lot.

Disk Blocks, Oracle Blocks, Physical vs. Logical I/O

Hi,
I would like to request for some clarification. Sam Alapati states the following in his book “Expert Oracle9i Database Administration:”
“The storage disks on which the Oracle blocks reside are themselves divided into disk blocks, which are areas of contiguous storage containing a certain number of bytes—for example, 4096 or 32768 bytes (4KB or 32KB, because each kilobyte has 1024 bytes). Note that if the Oracle block size is smaller than the operating system file system buffer size, you may be wasting the capacity of the operating system to read and write larger chunks of data for each I/O.”
There are several questions stemming from the above discussion:
1.     Is the “file system buffer size” the same as the size of a disk block?
2.     Is the disk block the unit of physical I/O?
3.     Does there exist such a term as “logical I/O” in Oracle’s nomenclature? With the help of my limited knowledge of database administration, what I understand from the term “logical I/O” is “reading or writing of one Oracle block,” which, in turn, requires several physical I/O’s depending on how large a multiple of the OS block size the Oracle block size is. In that case, does setting the Oracle block size to, say, 8 KB, when the OS block size is, say, 2 KB then mean that one logical I/O would involve four physical I/O’s? Please correct me if I am mistaken.
Thanks,
Karim

I second that.
For all questions about the very basic concepts in the world of oracle db, you should read the, erhm, yes Concepts guide (read it back and forth a couple of times, then keep revisit).
Also via the tahiti page you can search or get books from libraries of the various server products from 8i, 9i, and 10g families.

Oracle 9i - Physical Storage

Hello,
I am new to Oracle and I need to find a way to move the physical storage of an oracle installation to a NAS device.
Currenty I have an oracle 91 instance running on a linux box.. unfortunately this box is running out of space..so I need to move only the physical storage to the NAS device..(Dell PowerVault NAS) I would still manage the oracle instance only thru my linux box.. this way I can store more data on my oracle instance
any help on this highly appreciated!
Vanniarajan

Leave the Oracle software on Linux. Your instance will continue to be hosted on Linux. All you would be doing is moving the dbf from the linux box to the NAS. NAS contains a file system which is created by the vendor's software. You do not install any OS on it. Make sure you have a valid backup before moving, just in case.
For example, we have a NetApp SAN box here. All the dbf of my 8i and 9i databases are on it and I have a Windows 2000 Server hosting the 8i instances and a Windows 2003 server hosting the 9i databases.

SGA size is 1 GB free but oracle starts physical read/write,why ?

Dear Friends ,
In my production server I observe that it takes the the data from the HDD where my SGA is still 1 GB free .
As far I know , In oracle , when the allocated SGA size is filled up then it reads the data from the HDD which is called "physical read/write " . I am using oracle 10g database . In performance tab(From Oracle 10g OEM) , when I see that oracle starts to read the physical data , at that moment I run the following query :
select sum(bytes)/1024/1024 " SGA size used in MB"
from v$sgastat
where name!='free memory';
and I found that still 1 GB memory are still free in the SGA .
In this moment , I want to know , is it possible to start the physical read / write while the SGA size are still free ?

Logical IO, Pure Logical IO, Physical IO

Can some one clarify the below
1) difference between Logical IO and Pure Logical IO. When do these occur?
2) Why high logical IO is not good for performance.
I am confused by reading about these three IOs and the order in which these get invoked. Thanks.

sk12345678 wrote:
Can some one clarify the below
1) difference between Logical IO and Pure Logical IO. When do these occur?Never heard it called that. Logical I/O means reading from cache. Physical I/O means reading directly from the storage device.
The confusion between the two is when there is a secondary cache. For example, database resides on a cooked file system (ntfs, ext3, etc). The kernel has its own cache for that file system. So when Oracle performs an I/O on a data block not in Oracle's buffer cache, that according to Oracle is physical I/O. However, that block could be in the kernel's file system cache - which means logical I/O.
So what seems to be physical I/O in such a case, may not always be physical I/O.
That said, never heard of "+pure logical I/O+".
2) Why high logical IO is not good for performance.Untrue. Logical I/O is faster than physical I/O and it that aspect, is "+good+" for performance.
However, a large percentage of logical I/O and very little physical I/O does raise a question as to how well the software doing that I/O has been designed. Why is logical I/O so high? This means the very same data blocks loaded into the cache is hit again and again and again...
Ideally, s/w should only do a single pass through data - not multiple passes. So non-optimally designed and coded s/w that does multiple passes through data will have artificially high amounts of logical I/O. Thus a high percentage of logical I/O can be a symptom of an underlying problem with the s/w.

Private interconnect oracle 10g RAC configuration

Can you please answer below questions?
Why does a private interconnect need a switch, and why is straight through cables not supported.

Hi,
Why do you need a switch between the nodes".When network plugs are pulled out from one node on a two node cluster, a split brain scenerio occurs. (just it's enough)
If you are using a crossover cable and you shutdown node (A) you will loose the network (private) link from node (B) (this happens in some servers.), Oracle RAC will not work with private network link down, both nodes will down and will not start until you get link on network private. (Goodbye high availability)
You will be very unhappy with the error ORA-29740. Prelude to suggest this note: Troubleshooting ORA-29740 in a RAC Environment [ID 219361.1]
There is no "why" Oracle RAC does not support crossover cable because RAC depends of SWITCH (it's a Hardware Requirements) and any problems in your environment Oracle will force you to implement a supported solution.
You will have implemented a poor environment, if you not use a GB switch for private network.
Oracle Words:
*Physical Layout of the Private Interconnect*
The basic requirements are described in the Installation Guide for each platform. Additional information about certification can be found on Metalink Certify.
The interconnect as identified by both subnet number and interface name must be configured on all clustered nodes.
*A switch between the clustered nodes is an absolute requirement.*

Issue with Engineer Multidimensional Model from Oracle Model

Here is the scenario:
1. Created logical star schema model including a dimension with nested subtypes (SuperTypeEntity1 -> Subtype 1 -> Nested Subtype 2)
2. Forward engineer to Relational model using Single Table implementation
3. Create Oracle 11g physical model definitions for the star
4. Define dimension, levels, and hierarchy in physiclal model
5. Create new multidimensional model, right click menu and execute "Engineer from Oracle Model"
Result:
Model and diagram built with correct dimension, levels, level attributes, hierarchy
Problem: The entity that the dimension levels are related to is the subtype entity that appears first alphabetically! What it should do is be related to the SuperTypeEntity since I used the Single Table implementation (IMO). I can manually change the property to pick the SuperType but then it loses the assignments for the Level Key and the Descriptive Attributes (which were defined in the physcial miodel) so I have to manually repopulate those properties.
Associated problem: Since I tend to do things incrementally (define a few dimensions at a time), everytime I re-run the engineering utility, it resets the dimension back to the wrong subtype everytime. (I like the fact that I can rebuild the multidimensional model iteratively to incorporate changes, but in this case it would be nice to "lock in" my manual changes).
My only work around at this point is to either only run the engineering utility once (which is pretty impractical) or temporarily prefix my super type entity with an "A" so it always comes up first in the list until I am done with all my iterations.

Hi Kent,
dimensional model is not well suited to use entity hierarchies.
I can manually change the property to pick the SuperType but then it loses the assignments for the Level Key and the Descriptive Attributes (which were defined in the physcial miodel) so I have to manually repopulate those properties.It seems all your key and descriptive attributes are in SuperTypeEntity1 (the root of hierarchy). How to proceed if some attributes (key +descriptive) are in subtypes, should SuperType be set as level entity again?

Physical Vs Logical Partitioning

We have 2 million records in the sales infocube for 3 years. We are currently discussing the pros and cons of using Logical partitioning Vs Physical Partitioning. Please give your inputs.

hi
there are two types of partitioning generally talked about with SAP BW, logical and physical partitioning.
Logical partitioning - instead of having all your data in a single cube, you might break into separate cubes, with each cube holding aspecific year's data, e.g. you could have 5 sales cubes, one for each year 2001 thru 2005.
You would then create a Multi-Provider that allowed you to query all of them together.
A query that needs data from all 5 years would then automatically (you can control this) be split into 5 separate queries, one against each cube, running at the same time. The system automatically merges the results from the 5 queries into a single result set.
So it's easy to see when this could be a benefit. If your queries however are primarily run just for a single year, then you don't receive the benefit of the parallel processing. In non-Oracle DBs, splitting the data like this may still be a benefit by reducing the amount of rows in the fact table that must be read, but does not provide as much value to an Oracle DB since Infocube queries are using a Star_Transformation.
Physical Partitioning - I believe only Oracle and Informix currently support Range partitioning. This is a separately licensed option in Oracle.
Physical partitioning allows you to split an Infocube into smaller pieces. The pieces, or partitions, can only be created by 0FISCPER or 0CALMONTH for an InfoCube (ODSs can be partitioned, but require a DBAs involvement). The DB can then take advantage of this partitioning by "pruning" partitions during a query, e.g. a query only needs data form June 2005
The DB is smart enough to restrict the indices and data it will read to the June 2005 partition. This assumes your query restricts/filters on the partitioning characteristic. It can apply this pruning to a range of partitions as well, e.g. 0FISCPER 001/2005 thru 003/2005 would only look at the 3 partitions.
It is NOTsmart enough, however, to figure out that if your restrict to 0FISCYEAR = 2005, that it should only read 000/2005 thru 016/2005 since 0FISCYEAR is NOT the partitioning characteristic.
An InfoCube MUST be empty in order to physically partition it. At this time, there is no way to add additional partitions thru AWB, so you want to make sure that you create partitions out into the future for at least a of couple of years.
If the base cube is partitioned, any aggregates that contain the partitioning characteristic (0CALMONTH or 0FISCPER) will automatically be partitioned.
In summary, you need to figure out if you want to use physical or logical partitioning on the cube(s), or both, as they are not mutually exclusive.
So you would need to know how the data will be queried, and the volume of data. It would make little sense to partition cubes that will not be very large.
physical partitioning is done at database level and logical partitioning done at data target level.
Cube partitioning with time characteristics 0calmonth Fiscper is physical partitioning.
Logical partitioning is u partition ur cube by year or month that is u divide the cube into different cubes and create a multiprovider on top of it.
logical Vs physical partitions ?

Is drop user cascade DDL statement will be reflected in physical standby DB

Hi,
Oracle 10G
Physical standby database
When issuing drop user cascade in Primary DB , Will the same be reflected in physical standby ? or there is any exceptions of applying DDLs and DMLs ?
Thank you in advance,
Mohamed

Will the same be reflected in physical standby ?
Yes.
or there is any exceptions of applying DDLs and DML
No, not in a physical standby.
You do some exceptions in a logical standby.
