Manipulations with physical and logical names

Hello ppl,
Is there any way to see/change phisical and logical names of object in one place/screen? I mean I want to set them to different values and see that change, but without fuzzu, complex way of changing naming and propagate modes.
TIA,
Alex

Mark,
Under project, preferences (from the main console) you can set the naming and also the propagation method. That's what I hate to do :) However, thinking deeper I find it ok - first finish with modelling and physical names, than correct logical names as needed without propaation to physical.

CPU patch procedure with physical and logical standby database in place

Hello All,
I've also placed this in the Upgrades forum, but perhaps this is the best place to have put it.
I'm trying to compile a decent set of steps for applying the CPUOCT2008 patch to our production RAC cluster which has both a logical and physical standby in place. I've read a tonne of documentation, including the CPU readme, DOCID 437276.1 and 278641.1. I''ve also read through the Upgrading Databases in a Data Guard Configuration chapter of Dataguard Concepts and Administration. The last doc mentioned is really for upgrading a full version of Oracle rather than applying a CPU (at least I think that's the case). DocID 437276.1 is rather sparse on details.
I guess what I'm trying to understand is the proper method for applying the patch with the logical standby in place. The physical standby looks pretty straightforward. After running opatch on it as well, it will basically have all of the changes applied to the primary shipped over and applied as per the normal primary/standby relationship. Will the same be true for the logical (having applied the patch, and then re-enabling SQL apply)? Should I aim to have it work that way? By that I mean start it up and re-enable sql apply and then upgrade the primary. Or, am I to apply the catcpu.sql script to it as well before re-enabling the sql apply? Am I wrong in regards to the physical standby as well i.e. should the catcpu also be applied directly to it?
Thanks very much in advance.
Cheers,
Chris

Given the fact that your system is far from main-stream I'd recommend opening an SR with Oracle Support Services (metalink) and asking them.
If you would like to publish a White Paper on your experience after you have successfully completed the project let me know off-line.

Separation of the physical and logical structures

Hi,
I am very new to Oracle database administration. While reading Sam Alapati's book "Expert Oracle9i Database Administration," I came across the concept of the separation of an Oracle database’s physical storage structures from its logical storage structures. In particular, Sam states the following in his book:
“This logical defining of Oracle's database structure has another fundamental motive behind it. By organizing space into logical structures and assigning these logical entities to users of the database, Oracle databases achieve the logical separation of users (owners of the database objects, such as tables) of the database from the physical manifestations of the database in terms of data files and so forth.”
I am not quite convinced about the value this separation of the physical and logical really adds to the task of database administration. Considering the way DBASE worked, i.e. each table used to be stored as a separate file, what would be lost if Oracle’s implementation were similar and each table (i.e. file) were to be assigned to a particular user. I am not sure of the value added by storing the data from more than one table in more than one file, effectively resulting in a many-to-many relationship between tables and files. Please enlighten me. I would really appreciate it.
Karim

and each table were to be assigned to a particular user. Don't know what you mean. In Oracle, every table has one and only one owner.
I am not sure of the value added by storing the data from more than one table in more than one fileIf an application has a thousand tables, would you rather manage 1000 files or 1?
In general, separating the physical from the logical allows the physical structure to change without affecting the logical (in theory at least). Even a table is a logical structure. We think of rows and columns, but it isn't stored the way we think of it. When we do a select statement, we don't have to write code to read each block, extract the contents, etc.
With partitioned tables, it is sometimes a good idea to split up partitions in such a way to get a performance gain. Like placing the most recent (and most queried) month of data on the fastest storage device. If you stuffed everything in to one gigantic file, you would lose that ability.
If you want to store each table as a separate file, you can do that with Oracle. For each new table, create a new tablespace, and then create a new file for the tablespace. Then come back to this forum in a year and tell us how it's going.

Hello,
Sys.dm_os_performance counter will only show counters related to SQL server not Physical disk if you run below query in SQL server it will not return any value so no disk counter is present.You will have to see it using perfmon.
select * from sys.dm_os_performance_counters where counter_name like '%disk%'
This can also be done through power shell but I dont have experience with that.You can search net for power shell query to see Windows perfmon counters

Changing ip of physical and logical host

I have a 2 nodes Sun cluster 2.2 working. I have to put it in another lan, so I have to change both Physical and logical host and terminal concentrator and console ip addresses. How can I do?
Thanks

I don't see a reply so I'll take a shot. Just like you have 0-9 for numbers and you can arrange them anyway you want, you still only have 0-9. You have the physical (system block and datafiles) which are somewhat static. Then you have the the logical (tablespace, segements, extents)which are volatile and connected by chaining (links) which may be all over the place in the physical but appears to be one whole unit in the logical. Just like an image on a TV screen wearing a red hat, you see a red hat (logical) but it is actual pixels which are chained or linked (data pointers) to each other by the color red. I hope that helps until someone comes by with a better answer.

Below is the details from the log file.Here I observed that response time for physical and logical query is 109 sec ~ 2 mins.Please provide me the helpful pointers.

Did you run the SQL from a client on the OBIEE server or your local machine? Does the Physical SQL on the OBIEE server against the DB run in 2 Seconds and when sent by the OBIEE server it takes 109 seconds?? Is that correct?

Export physical and logical details on ASA 5520 and 8.0 software

Hello...does anybody know if there is any way to export details of the physical and logical interface details (including interface descriptions) to Excel, PDF or and other format from the command line or ASDM?
Thanks,
John

Export directly in xls, xlsx or pdf - no.
The output of "show run interface" or "show interface" is pretty structured however and easily parsed by Excel - either manually or via a macro. See output below (you can omit the interface identifier to get all interfaces. I used one for brevity.)
One can build a script to log in, perform an arbitrary command logging the output to a file which can then be massaged to extract the information you want in a suitable format (csv, etc.). Once in Excel it can be saved as pdf if you're so inclined.
Of couse, some of the full-featured network management tools do a lot of this (and lots more) if you have them.

Difference between physical and logical standby database

What is the difference between physical and logical standby database?

Hi,
Physical Standy where its a read only DB.
Logs are applied.
Logical Standy where it can be Read / Write DB and the logs are applied in terms of SQL Statements.

Physical path and Logical name in File adapter

Hi All-
I am using a file adapter, in which i need to specify the physical path or logical path.
In dev environment my file adapter's input path is /c01/interface/dev/input, but in my test environment it is /u01/interface/test/input.
So everytime I have to change the path and deploy it in two different environment.
I am using unix environment, is there any way i can use some environmental variable $INPUT_DIR and use it in logical name so that in logical name i can use as $INPUT_DIR/input, where in dev $INPUT_DIR will be /c01/interface/dev and in test environment it is /u01/interface/test.
I have tried this but there is still some probelm, I want to know is the approach I am using is correct? or is there any other solution for it?
Regards,
Sreejit

Hi,
1. physical name: use a specific directory (e.g. /u01/....
2. logical name: use a LogicalDirectory like "InputFileDir" and rewrite this inside the bpel.xml

and
http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28981/appx_deploydesc.htm#CHDBDIIF

ln -s /u01 /c01

Physical and Logical path

Hello,
what is a physical file and logical file in PATH table of SAP.
Plz help,
aafaq

Hi aafaqhusain,
1. logical file path is nothing but a    IDENTIFIER/STRING/NAME
= the name by which
   we refer to that file.
(in our programs)
2. The physical location of that file,
   may change from server to server,
or from time to time.
(hence, we do not use hardcoded physical path,
   in our programs,
   but instead use this MAPPING of logical path,
to the physical path)

amit m.

Help with JSP and logic:iterate

Oh think I got it...
but one thing I'm not sure is...
If I use "<jsp:useBean id="RD" class="RequestData" />", do I still need "<%@ page import="RequestData" %>"?
I tried without and it gives me error...

How to insert data into datagrid dynamically and also programatically with data and column names being retrived from a xml file..

iam not able to insert data into datagrid corresponding to the column names..as iam inserting both data and column names programatically..ie iam not able to co relate the data with the column names.plzzz help me asap

A DataGrid is row-based rather than cell-based with each row
corresponding to an item in an underlying collection (specified in the
dataProvider property). In order to add data to a DataGrid you
manipulate the underlying collection, rather than the grid directly.
Based on the limited description of your problem I would imagine you
would need to create dynamic objects with property names that correspond
to the dataFields of your dynamically created datagrid columns.
So if you had created columns with dataFields "alpha", "beta" and
"gamma" on your datagrid, you could create an item in your grid by
adding the following object to your dataProvider:
var gridItem : Object = new Object();
gridItem.alpha = "alphaValue";
gridItem.beta = "betaValue";
gridItem.gamma = "gammaValue";

Physical and logical partation of cube

hi
can i get scenerio for logical and physical partation of cube.
based on year or calmonth that is called physical partation? or not
what is logical partation

Hi sunil,
Partitioning is mainly done to increase the performance by optiomizing the Time Utility.
Physical Partitioning is the partitioning done at the database level and to do so, we can partition based on the Time,date so on... In terms of Cube partitioning we usually use 0CALMONTH, 0CALYEAR or 0FISCYEAR.
And
Logical Partitioning is the partitioning done at the Query level while retriving data from the cube. This is said to be Logical because the data is not partitioned at the database level.
Ex: Restict the Query using 0CALMONT,0CALYEAR.
Hope this helps you and solves your problem,if it helps assgn pnts.
