Logical/Physical

Hi
ABAP/4 Dictionary contains the (Logical/Physical) definition of the table
explain

Hi frend,
ABAP dictionary contains logical definition of table in the sense that it makes use of different logical databases and search tables to intercorrelate each table table so that it becomes a logically defined tables.

Can we create logical/ physical schema by running any script (unix/window)?

I wish to create logical/ physical schema in oracle data integrator
by running any windows or preferably unix script.
is there any method or scripts provided in ODI?

I think you could insert info into Matser Respository tables:
Connect info: snp_connect
Logical Schemas : snp_lschema
Physical Schemas: snp_pschema
Or you may write some sql to do this.

STANDBY LOGICAL & PHYSICAL

Using Oracle10gR2
If i create a new tablespace or add datafile on the primary db will it automatically create on the STANDBY LOGICAL & PHYSICAL
Please advice

Hi,
i had logged metalink SR,go ahead with below ACTION PLAN response received
primarydb
=======
create tablespace per datafile 'c:\DATA\perfstat.dbf' size 200M autoextend on;
Logical stdby db [explicitly]
=====================
create tablespace per datafile 'c:\DATA\perfstat.dbf' size 200M autoextend on;
Physical stdby db
=============
No statements to execute, the above changes to primary will automatically get
updated here.
Since i do not have a test environment to check, my concern is
1. Above steps are correct sequence
2. Will it stop my replication to logical & physical stdby
3. Has anyone done this

DataBase Adapter Rollback option for Logical/Physical Delete in SOA 11g

Hi All,
We have a requirement where we need to rollback the logical delete performed by the DB Adapter (after polling a table) if there is any failure in the process down the line. We are trying to implement this using Mediator or OSB. For example if we are polling a table for changed records and performing logical delete, down the line if the business service (OSB) or the external reference (Mediator) are down/faulted, the records which were logically deleted are not getting rolled back in the table. Would any one please let me know if you have come across the same kind of scenario?
Is there any property we need to set while configuring the polling DB Adapter?
Thank You.

Thank you very much for the reply Anuj,
I have created a db adapter which polls on a table with logicaldeletestrategy in JDeveloper 11g,
then I imported the XSD, mapping.xml, wsdl and JCA file into OSB using OSB consol. In the console
I generated proxy and wsdl for that proxy using JCA file. Then created one more db adapter in JDev
which inserts the records polled by the first db adapter into another table, followed the same
process of importing the above mentioned 4 files and generated a business service. In proxy service
route node I am using a transformation (which also I imported from Jdev) to route the data polled
by proxy service to the business service. Here I am using an XA datasource both the JCA's also
I made the 3 changes reccommended by Arun but still I am not getting the results.
I tried physical delete same issue with that too. When I am doing physical delete the proxy service
atleast picking up the records and deleting them. But when I tried logical delete the proxy is not even
picking up the records. Am I missing anything here?
Thank You,

Trying to import .dmd file and want to see the logical & physical diagram

Can some one guide me how to import a .dmd file which i got from client. In my local machine i downloaded datamodeller and installed.
When i am trying to import the same, i am not able to see any logical or physical relationship diagram.
Thanks inadvance..

Hi,
As well as the .dmd file, the folder containing the .dmd file should also contain a folder with the same name - e.g. MyModel.dmd plus folder MyModel.
If you've only got the .dmd file, you will need to get the associated folder and all its contents as well - the most convenient way is to get your client to use Winzip to zip up the .dmd file and its companion folder.
You can then unzip it and open the .dmd file in Data Modeler, using Open on the File menu.
The Logical and Relational diagrams should then be shown on the Logical and Relational tabs in Data Modeler.

RE logical/physical standby database

1. Why logical standby database is SQL apply, and Physical standby database is redo apply? What ‘s the meaning/objective for that? (pls don’t tell me what is SQL/redo apply)
2. As we know, a logical standby database can be used for reporting and querying if primary database is down, why we still need a physical standby database (it can’t do that during recovering process, it just a same copy of primary database)? Why not just go ahead to set up only a perfect logical standby database? (just because logical one can’t accommodate all kinds of data type???)
3. Combined with Real time Apply and maximum protection, we can achieve a zero data loss, but could we achieve a zero downtime? Why or why not?

BACKUP VALIDATE vs VALIDATE in checking logical/physical corruption

Hello all,
I am checking if our 10gR2 database has any physical or logical corruption. I have read in some places where they state that VALIDATE command is enough to check database for physical corruption. Our database was never backed up by RMAN specifically before. Are any configuration settings needed for running BACKUP VALIDATE command? The reason I am asking is because just the VALIDATE command returns an error and BACKUP VALIDATE command runs without error but it is not showing the
"File Status Marked Corrupt Empty Blocks Blocks Examined High SCN" lines.
I used the command in two different formats and both do not show individual data file statuses:
RMAN> run {
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE DEVICE TYPE DISK PARALLELISM 10 BACKUP TYPE TO BACKUPSET;
BACKUP VALIDATE CHECK LOGICAL DATABASE FILESPERSET=10;
RMAN> BACKUP VALIDATE CHECK LOGICAL DATABASE
RMAN> VALIDATE DATABASE;
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00558: error encountered while parsing input commands
RMAN-01009: syntax error: found "database": expecting one of: "backupset"
RMAN-01007: at line 1 column 10 file: standard input
However on a different database already being backed up by RMAN daily, BACKUP VALIDATE output shows list of datafiles and STATUS = OK as below:
List of Datafiles
=================
File Status Marked Corrupt Empty Blocks Blocks Examined High SCN
How can we check every individual datafile status. Appreciate your responses. Thanks.

Hi,
After you have run:
BACKUP VALIDATE CHECK LOGICAL DATABASE You can use sqlplus and run:
select * from v$database_block_corruption.The output will tell you which block in which datafile is corrupt.

Logical / Physical Arch export imort

Hi,
I am training to import interfaces from one Environment(D) to another(D1), I had created Master and work repositories with different ID's.
How I have to export and import logical and physical Arch information.
Appreciate you help

Do you have a reasoning for having one master per environment ?
The best approach is to have one Master and several work (one per environ) underneath. However, certain organizations have production system segregated by a firewall and that warrants a different Master for production system.
But if your setup doesnt have network configuration issues, spare yourself the complexities of having multiple master repositories.

Logic & physical path

hi friends,
could u plz tell me what is logical path? and what is physicall path?
and also i want to know how to link ogical path and physicall path?
plz tell me in details.
with regards,
Priya.S

Hi Priya,
Logical File Names
Use
To save data in a file in the cache modes Main Memory Cache with Swapping, Flat File Cache per Application Server, or Cross-Application Server (see Cache Mode), the following specifications must first be set:
●      Definition of the logical file path and assignment to a platform-specific physical path
●      Definition of the logical file name
From the Cache Monitor screen, using Logical File Names, you can access the complex table maintenance for logical file paths and names. The table maintenance consists of several subdialogs (views). SAP has delivered a proportion of the required settings.
You need to check these settings and make any necessary adjustments for your file system before you can use the persistent OLAP cache with a flat file as a background store.
Note that these assignments are subject to settings made for the transport connection (You need a request that can be transported).
Features
The following section gives an overview of the subdialog in the table maintenance using an example configuration. For more information about the procedure, see Defining Logical Path and File Names.
You can choose the following subdialogs using the dialog structure:
Logical File Path Definition
The (platform-independent) logical file path is evaluated at runtime to generate the (platform-dependent) physical path (see Assignment of Physical Paths to Logical Path).
Two examples of this are:
●        Logical file path: BW_OLAP_CACHE
Name: BI OLAP Cache
●        Logical file path: BW_OLAP_CACHE_SPAN
Name: BI OLAP Cache Cross-Application Server
Assignment of Physical Paths to Logical Path
At runtime, the physical path assigned to the corresponding operating system is generated from the logical file path.
Since the physical path is platform-dependent, the customer has to specify it. The closer the file is to the application server or, with the cross-application server cache mode, to the application server, the faster it can be found and read.
Log(ical) path: BW_OLAP_CACHE
Name: BI OLAP Cache
Syntax group: UNIX (all Unix platforms)
Phys(ical) path: /usr/<SYSID>/global/<FILENAME> (You can choose the path up to <FILENAME> according to your own configuration.)
If you cannot find the relevant syntax group for file names and paths for your operating system, you can define your own (see Syntax Group Definition and Assignment of Operating System to Syntax Group).
The <FILENAME> parameter must always be set for the physical file name (see Logical File Name Definition, Cross-Client). At runtime, the complete platform-specific file name is automatically formed from the physical path and the physical file name.
Logical File Name Definition, Cross-Client
At runtime, a complete platform-specific file name including the path is generated for a (platform-independent) logical file name.
In the following example, cache data is stored on an application server:
Logical file: BW_OLAP_CACHE (we recommend you use the delivered attributes for the logical file).
Name: BI OLAP Cache Files
Phys(ical) file: CACHE_<HOST>_<SYSID>_<PARAM_1>
Data format: BIN (binary)
Application area: BW (Business Information Warehouse)
Logical path: BW_OLAP_CACHE (see Logical File Path Definition). Input help is available.
In the following example, cache data is stored cross-application server:
Log(ical) file: BW_OLAP_CACHE_SPAN
Name: BI OLAP Cache Cross-Application Server
Phys(ical) file: CACHE_<SYSID>_<PARAM_1>
Data format: BIN
Application area: BW
Log(ical) path: BW_OLAP_CACHE_SPAN
Note that a particular schema is prescribed for the physical file name:
●      For application server storage (see Global Cache Parameters and Cache Mode Main Memory Cache with Swapping and Cluster / Flat File Cache per Application Server):
CACHE_<HOST>_<SYSID>_<PARAM_1>
●      For cross application server storage (see Global Cache Parameters and Cache Mode Cluster / Flat file Cache Cross-application Server):
CACHE_<SYSID>_<PARAM_1>
The following table offers an overview of the variables that are only replaced with actual values during runtime:
Variables in Physical File Names
Variable
Meaning
<HOST>
Computer/server name (for SY-HOST).
If the data is stored cross-application server, this variable is not required.
<SYSID>
System ID
For example, if two different BI systems are running on one application server, this variable serves to differentiate the systems so that they do not overwrite each other.
<PARAM_1>
External parameter 1 (sequential number in HEX)
Definition of Variables
If you want to use variables in physical file names and paths, you can define these by choosing New Entries.
Syntax Group Definition
You can define a new syntax group for operating systems with the same syntax for file names and paths by choosing New Entries.
Syntax grp: UNIX
Name: All Unix platforms
Length (of file name)
Extension: Choose this option if the data format for the logical data name is allowed as the file name extension for this syntax group.
Active: Choose this option if the operative system for this syntax group is used in the available system configuration.
Assignment of Operating System to Syntax Group
You can assign your operating system to a syntax group by choosing New Entries if necessary.
OP system: SunOS
Name: SUN Unix

Margins with Logical / Physical page layouts

Dear all,
We have created an Oracle 6i report with 2 horizontal panels as we couldn't fit in all the fields into one page. It’s the first time I have worked with is and I am little unsure of what i am doing.
The layout contains many repeating frames so on some cases when we preview the report it my go onto a third page but as its not all cases I don't want to create a 3rd panel.
The problem I have is that when the 3rd page is created the text appears in the middle of the page and I don't know how to tell it to print say 10 lines from the top.
Any ideas.
I apologies in advance if this is simple and offends anyone; I just couldn't come up with the answer.
Eileen

Danny, good try but that's not the problem. Margins and so forth apply to physical pages, and we get the margins we want.
But we have a logical page that spans 2 physical pages, and there is no way I know of to force a page break at the end of the first physical page.
Let's say you have 9 inches of vertical usable space on each physical page, after taking away the margins.
You define your logical page to span 2 physical pages, so it has 18" to work with. And it treats those 18" as a single continuous area. So if a line of text that renders as starting at 8.95" down, and finishing at 9.08" down, you'll get the top half the bits for each character on the first sheet of paper and the other half on the next.
Everything's nice if you use character mode, or if you have 1 logical page for every physical page. However, there should be some way to control layout on the physical pages when the logical page spans them. If there is, I've never found it.

Logical & Physical names !?

howdy,
what's the difference between Logical Jndi names ( like: "java:/comp/env" ) and Physicak ones ( like: "ejb/xxxLocalHome" ) in EJB ?
and can we customize our container to which it should use ?
--Behrad

what's the difference between Logical Jndi names (
like: "java:/comp/env" ) These are EJB references. References can be configured for some component (WEB application, EJB bean) so it can find an EJB without knowing it's real JNDI name.
and Physicak ones ( like:
"ejb/xxxLocalHome" ) in EJB ?Those are real JNDI names. All EJB's have a real JNDI name.
and can we customize our container to which it should
use ?You can use references (use deployment descriptor to configure them) if you want.
But also all EJB's will have real names , too. So container supports both.
Read "Masterering EJB' s" if you want to know more about it.

Create content modell, logical/physical document class, TA CT04/cl02/dc10

Dear experts,
Im about to get to know the SAP DMS. Content Server is already running working as well as the content repositories. I now wanna set up a content modell for testing with knowledge provider.
Im a bit confused about the different ways of doing that. What is actually the difference between creating a CHAR in TA ct04, creating a class in Cl02 with type 017 and the alternative of creating a content model with TA SRMCMCREATE or directly in the document modelling workbench.
Once ive hopefully understood the difference how can i start actually creating / uploading real (physical documents) cause in dont understand what TAs cvn01n/02n/03n are for.
There is a large number of function modules for kpro. Fo example when testing SDOK_LOIOS_CREATE i have to enter an RFC destination. What do i have to type in as RFC destination intending to store in content repositories of content server?
I know thats more than one question at a time but i would be very pleased some of these get answered.
Thanks a lot in advance.

Dear Christian,
I would like to start providing you information with CT04 question. Here the CHAR value is used for maintaining the type of classification characteristics. The CHAR entry stands for 'Character' type which
means you can add alphabetical and numerical values to this classification characteristic. Transaction CT04 is normally used for creating classification characteristics. In CL02 you can create a class for
classification and then add the characteristics to it. In the standard class type 017 is used for classifying document info records.
Transaction CV01N/CV02N/CV03N are used in standard for document managment functionalities. Here you can create/edit/display your document info records. These document info records are like a frame for your original files which could be added to an info record and then checked into your Content Server.
During this check in function the KPRO function modules are used too.
For further information I would recommend you to see the SAP online documentation under http://help.sap.com.
Best regards,
Christoph

Logical & Physical Standby

1) Is Logical Standby built up on Log Miner?
2) Is it not possible to use Logical Standby without turning on supplemental logging?
3) Is there any relationship between LGWR & LNS in Log Transport Mode?

1) Is Logical Standby built up on Log Miner?
