Create a standby logical database in 10g

Hi,
My OS is Windows 2003, using oracle 10g software.. I want to know steps to create a logical standby database from primary database? I read the Dataguard concepts and administration guide, its confusing where it says to add the roles for primary and standby database in init.ora file? Could someone please provide steps to configure...
Thank you.

If you need the entire database to a single location ... use Data Guard.
If you need to specify tables, columns, schemas, rules, and are in a
publish-subscribe situation use Streams.
Both are share a common architecture.
refer this for comparison,

Copy/create program with logical database

Hi
I need to create a program with the same selection-screen as SAP standard program RPRAPA00.
RPRAPA00 is using a logical database, but even that I have passed in the PNP in the attributes of my own progam, I don't get the selection in the top (buttons, key-date info + selection info).
The rest of my program looks fine.
Any ideas how I get the missing selections into the selection-screen?

Hi,
Define pernr table under tables statement then and use GET PERNR event.This get event is followed by End-Of-Selection.
Syntax: Tables pernr.
Get pernr.
Try, activate and test. This should solve your problem.

Creating a new Oracle Database using 10G Grid Control

Hi
Is it possible to create a new database using the 10g Grid COntrol.

The way to create a database with EM, is by using Provisioning procedures. For instance with the Oracle Clusterware / RAC Provisioning For UNIX, you can provisioning Clusterware, ASM + ASM instance creation and DB Software. Then by provisoning you would create a database. There are also procedures to extend a cluster.
So, provisoning is the way to go!

Creating an Oracle Spatial database in 10g and connecting ArcGIS

I have a set of shapefiles that I want to convert into Oracle Spatial 10g and then be able to view these with the capability of ArcGIS 9 (without using ArcSDE).
From what I've read, I think this could be done by using ODBC. Once that connection is made, will I then be able to use the full functionality of ArcGIS especially read/write functions to edit the information in Oracle Spatial?
What data formats does Oracle Spatial in 10g support. I am concerned about raster data, CAD data, Survey data etc

The shape files can be loaded into Oracle spatial using shp2sdo.exe available on web.To view the GIS data in ArcGIS ,ArcGIS needs the layers to be registered.Therefore you need Arcsde for registering the layers.But for viewing the data in Arcgis we do not need arcsde ,we can view the data using direct connect.For editing the data we can use ODBC connection.
About raster data,we can load tiff,jpeg,bmp,png,gif using georaster tools provided by oracle into georaster tables.
Thanks

Steps to create LOGICAL DATABASE in sap

hi guys,
i have gone through many documents about LDB. But, i didnt get the steps to create a LDB.
plz provide me with the steps to be followed to create a LDB.

Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
Database access programming: Once youu2019ve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
ABAP/4 (Advanced Business Application Programming language, version 4) is the language created by SAP for implementation and customization of its R/3 system. ABAP/4 comes loaded with many predefined logical databases that can construct and table just about any conventional business objects you might need in any canned SAP application. However, you can also create your own logical databases to construct any custom objects you care to define, as your application requires in ABAP/4. Hereu2019s a step-by-step guide:
1. Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2. Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3. Youu2019ll be prompted for a short text description of your new logical database. Enter one. Youu2019ll then be prompted to specify a development class.
4. Now comes the fun part! You must specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youu2019ve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you donu2019t have to write a single line of code.
Watch out!
The use of very large tables will degrade the performance of a logical database, so be aware of that trade-off. Remember that some tables in SAP are very complex, so they will be problematic in any user-defined logical database.
Declaring a logical database
Hereu2019s another surprising feature of logical databases: You do not assign them in your ABAP/4 Code. Instead, the system requires that you specify logical databases as attributes. So when you are creating a report, have your logical database identifier (the name you gave it) on hand when you are defining its attributes on the Program Attributes screen. The Attributes section of the screen (the lower half) will include a Logical database field, where you can declare your logical database.
Logical databases for increasing efficiency
Why else would you want to create a logical database? Consider that the logical databases already available to you begin with a root node and proceed downward from there. If the data object you wish to construct consists of items that are all below the root node, you can use an existing logical database program to extract the data, then trim away what you donu2019t want using SELECT statementsu2014or you can increase the speed of the logical database program considerably by redefining the logical database for your object and starting with a table down in the chain. Either way, youu2019ll eliminate a great deal of overhead.
Reward if useful.

Change selection screen in LDB (KDF logical database - NOT HR)

Hi All,
Iu2019d like to use KDF logical database to keep the dynamic selections since user wants to use it but I need to change the selection screen itself. The existing variants for KDF donu2019t meet the user requirements. Some fields I need to hide some add. Like I want to u201Cremoveu201D the field u2018Posting periodu2019 (MONAT) (which is available in dynamic selection screen) and put it on the u201Cmainu201D selection screen.
Do I need to create my own logical database or there is a way around?
Could someone give me a practical advice or sample of solution?
Thanks a lot.

Thanks Himanshu,
I did as you suggested but problem is that it does not allow me to hide the whole block.
I have 3 filelds actually on block KD_0 I need to hide (its from selection screen of KDF logical database.)
SELECT-OPTIONS: KD_LIFNR FOR LFA1-LIFNR MATCHCODE OBJECT KRED.
SELECT-OPTIONS: KD_BUKRS    FOR LFB1-BUKRS.
SELECTION-SCREEN END OF BLOCK KD_0.
PARAMETERS KD_INDEX AS SEARCH PATTERN FOR TABLE LFA1.
What I did is below. I used sp instead of u201C=u201D since it has many screen for field KD_LIFNR(for frame, text etc).
And when I did just for KD_LIFNR it was hidden but when I did the same for KD_BUKRS it was not hidden . The field has stars u201C*********u201D in it.
Same happen with KD_INDEX. The name of the field is hidden but field not and it filled with ********. Do you have any ideas what it can be?
I debugged it to catch all screen names but no luck
loop at screen.
    if screen-name cp 'KD_LIFNR' or
    screen-name cp 'KD_BUKRS' or
    screen-name cp 'KD_INDEX' or
    screen-name = '%B000003_BLOCK_1000' or

ABAP Logical Database ADA

Hi All, I am quite familiar with Logical Databases but I need to understand the following.
1) I am using LDB ADA, but I want to use my own Selection Screen and not the default one that the LDB provides. I know I must put something in AT SELECTION-SCREEN but am unsure what.
2) Once I get the data, I want to store the data in an internal table - how do I go about doing this? If you can provide a code example that would be great.
Points for any relevant help.

Hi,
A logical database is a special ABAP/4 program which combines the contents of certain database tables. You can link a logical database to an ABAP/4 report program as an attribute. The logical database then supplies the report program with a set of hierarchically structured table lines which can be taken from different database tables.
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
Database access programming: Once youve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
Heres a step-by-step guide:
1) Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2) Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3) Youll be prompted for a short text description of your new logical database. Enter one. Youll then be prompted to specify a development class.
4) Specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you dont have to write a single line of code.
Noted point is we cant add any selection criteria thru our se38 program if you are attaching any LDB to program.Ist of no use.
If you want to change selection criteria to the existing LDB, you have to goto SE36 tcode and provide LDB name and choose "Change" mode by selecting "Selections" Radio button.
declaration of params is different compared to normal se38 program in some aspects.
PARAMETERS :p_curr LIKE bkpf-waers FOR TABLE bkpf OBLIGATORY.
this BKPF table should be one of the node in the "Structure" Radio button.

Logical Database PGQ structure usage

Hello Everyone,
I have a question regarding Logical Database(LDB) usage...How to use the structure defined in LDB. We are using PGQ Logical database in one of custom programs. The structure of the LDB as hierarchy or tree is:
QALS
 QAVE
 QMFEL
 QAPO
 AFFHD
 QAMV
 QAMR
 QASE ---> From this table
 QASV
 QASR ---> From this table
and etc
The code was something like this in the program:
GET QALS.
GET QAPO.
GET QAMV.
GET QAMR.
Now, my requirement is to get data additionally from QASE and QASR tables..So, I tried modifying the code according to the hierarchy structure defined in the PGQ LDB(check bold statements):
GET QALS.
GET QAPO.
GET QAMV.
GET QAMR.
GET QASE.
GET QASV.
GET QASR.
But in runtime I see that QAMR and QASE is filled up with # data ...I am not sure if is right way to do....Is this the way to use the structure defined in the Logical database? QAMV and QASV lie in the same level of hierarchy and I have to use them to get QASE and QASR data...Let me know, if I am not clear...
Thanks for taking your time and I appreciate if some one can help me.

Hi Ankur
You can use program SAPDBPGQ that is program created to test logical database PGQ. Then you can get only part responsible for nodes QALS, QAPO and QAMV

Dear Spandana,
Go through the below description of LDB. I hope you wil get a fair amount of idea.
SAP comes loaded with all the extras. Among the extras that are most helpful to IT managers are all the access routines needed to pull any business object that managers can think of out of SAP databases. However, SAP has not thought of everything where your particular applications are concerned. SAP organizes its standard database tables to service business units based on conventional business applications. Itu2019s likely your business requires something new, perhaps even something exotic. In that case, you will need to create a new database, using information from different places. Basically, you need a logical database. You need to create a virtual business data object repository consisting of a new kind of record or table that suits your purposes. In addition, the repository should be composed of information that is actually stored in a number of different locations, none of them necessarily logically associated with one another. Letu2019s take a closer look at creating logical databases.
A case for a logical database
Suppose my company manufactures widgets of the most obscure variety, and they are components of other widgets. I sell my widgets as raw material for the more sophisticated widgets built by others, but in some cases I actually partner with other manufacturers in creating yet another class of widget. Now, in my world, I consequently have customers who are also partners. I sell to them and I partner with them in manufacturing and distribution. Also, I need an application that uses both of these dual-use relationships.
Essentially, I have a customer database and a partner database. Neither contains records that are structured to contain the identifying particulars of the other. Thus, I need a hybrid database that gives me tables detailing these hybrid relationships. What can I do? I can go the long way around and write a new database, pulling information from both and creating new objects with a customized program that I write by hand. However, this process is cumbersome and contains maintenance issues. On the other hand, I can use SAPu2019s logical database facility, create my logical database in a couple of minutes, and have no maintenance issues at all.

q1]] What is the difference between LOGICAL DATABASE and VIEWS?
q2]] Why are alphaneumeric characters called so ?

Hi
q1]] What is the difference between LOGICAL DATABASE and VIEWS?
Logical Databases
Logical databases are special ABAP programs that retrieve data and make it available to application programs. The most common use of logical databases is still to read data from database tables by linking them to executable ABAP programs.
Logical databases contain Open SQL statements that read data from the database. You do not therefore need to use SQL in your own programs. The logical database reads the program, stores them in the program if necessary, and then passes them line by line to the application program or the function module LDB_PROCESS using an interface work area.
Logical Databases - Views of Data
A logical database provides a particular view of database tables in the R/3 System. It is always worth using logical databases if the structure of the data that you want to read corresponds to a view available through a logical database.
Please got through the link where you can find how create or modify logical database.
http://www.datamanagementgroup.com/Resources/Articles/Article_1005_2.asp
q2]] Why are alphaneumeric characters called so ?
Alphanumeric characters are combination of alphabets including Uppercase letters (A..Z) and lowercase letters (a..z) , and Numerals(0123456789) .
This Can be defined with character strings.
A character string is a data type that consists of a series of alphanumeric characters.
Each character string has a code attribute (ASCII, EBCDIC, or BYTE). It defines the sort sequence to be used for comparing values.
