How to use temporary database?

hi
i am using timesten as cachedb for oracle database。i have some problem about how to use temporary database？
1） what's the difference between temporary and non-temporary database，if i use awt cache group,then timesten will automatically replicate all change to oracle database , even if timesten crashed，i can set up another timesten quickly，no data loss？
2）since all data is in oracle database，does timesten‘s transaction log and checkpoint file useful ? does timesten need backup ?

Temporary databases have very limited usefullness; you can't use them with replication or caching for example. They are a very 'niche' use case; I'd recommend that you avoid them for mainstream use.
TimesTen checkpoiint and transaction log files are always required (except for Temporary database which do not have checkpoint files but do have log files).

  • How to use Logical database in function module?

    I will create a function module in HR.
    but how to use Logical database  in function module ?  Logical database PNP always show screen.in function (RFC) code , it is a matter.

    You cannot attach the LDB to the main program of the function group.
    - So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
    - Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
    - Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

  • How to use Temporary Table in PL-SQL

    In MySQL there is no Temporary table concept.
    So for intermediate calculation I have created a table as below
    create table SequenceTempTable
    SessionId VARCHAR(50),
    Sequence VARCHAR(500),
    CreatedDate DATE
    ) ENGINE=MEMORY;
    Whenever I invoke a SP, I load the data into SequenceTempTable using Session Id as below
    CREATE PROCEDURE `GetSequence`(
    IN Start_Date VARCHAR(25),
    IN End_Date VARCHAR(25)
    BEGIN
    SELECT UUID() INTO v_SessionId;
    INSERT INTO SequenceTempTable values (v_SessionId,'1,2,5,3',now());
    required code
    DELETE FROM SequenceTempTable WHERE SessionId = v_SessionId;
    COMMIT;
    END;
    i.e. I have created a table as temporary table (created once),
    and load the data using Session Id and once session specific intermediate computation done,
    I deleted the session specific data.
    Could you give me examples of How to use Temporary table in PL-SQL code with respect to my above example.
    Because I have gone through creating Temporary table but I stuck with use in PL-SQL. I mean to say Is there any need of creating table in advance before invoking SP.
    And one more thing as in MySQL temp table I created which is using MEMORY engine i.e. this table will always be in MEMORY so there is no need of writing data on disk.

    Hi Sanjeev
    Read about GTT here
    http://www.oracle-base.com/articles/8i/TemporaryTables.php
    GTT always contains just session specific data. \
    In case you want to use the GTT in the same session again you can use option
    ON COMMIT PRESERVE ROWS;
    Or if it is used just once in the session use can use
    ON COMMIT DELETE ROWS;
    Do remember that for GTT the data of one session can not be accessed in other session.
    Also you can go away with Delete from GTT if not used again in same session.

    A temp interface CANNOT be used as a derived table in ODI 10g.
    All you can do is to drag and drop the temp interface as the source in the mapping.

  • Why and how we use Logical Database?

    Can anybody explain with example why and how we use logical database?
    Regards,
    Rajan

    Hello,
    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.
    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.
    u2022     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.
    u2022     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.
    u2022     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.

  • How to use another database schema in Dictionary project

    Problem description:
    1)     I want to use Developer Studio to create my own J2EE project. Then I have to use Dictionary Project to maintain my database.  My database is Oracle.
    2)     I created tables in Dictionary project and deployed to database
    3)     After that I found my tables were deployed into SAPSR3DB schema.
    Question:
          What can I do if I want to deploy my tables into another schema other than SAPSR3DB?  In real cases I want to separate my tables from the WAS system tables.

    Hi Chaoran,
    If you want to use external database with Java dictionary tables..
    Right click on the Java Dictionary Table, from the menu select <b>Create DDL script</b>, then select to which data base you want to generate scripts. It will generate .sql scripts, use this scripts in your database to create tables. But the same time you need to create Data sources in Visual Administrator for your oracle system.

  • How to use Derby database in embedded mode in WebLogic 12c?

    I have a JavaEE-6 application that uses Derby database in embedded mode. It uses JPA for persistence. Everything works fine in Glassfish but now I am trying to port it to WebLogic 12c and having issues setting up Derby database in WLS in embedded mode. The derby setup in WLS asks for Host/port and does not have the embedded mode option. Any help is appreciated.

  • How to use access database

    is it possible to use access database in visual basic 2012

    Hello,
    There are two main methods for working with MS-Access databases in Visual Studio with VB.NET. One method you go through several steps which the IDE data wizard creates strong typed classes and assist with binding fields in the database table to controls
    such as a DataGridView, ListBox, TextBoxes etc. The second method you actually write all the code which can go in two different directions.
    Which one to pick is dependent on your expertise in general with VB.NET. Both have advantages and disadvantages.
    The following shows the beginnings of working with data wizards in the IDE while
    this page is an index for the link just provided with a mixture of examples.
    If open to suggestion and dependent on your needs please consider looking at using SQL-Server since there is an Express version of SQL-Server installed with Visual Studio. SQL-Server is overall and better choice but does not mean it's best for you at this
    time but worth considering.

  • How to Use Temporary table on report builder

    Hi community!
    Well, i'm trying to build a temporary table based report in Oracle Report Builder. in "After Parameter Form Trigger" I've placed a stored procedure that populate a temporary table and I've based my report on it. The problem is Report shows no data. When i execute this procedure directly on database and i perform a select on my temporary table, it show all inserted data.
    I hope somebody can to help me because I tried many ways to build this report with my temporary table and always looks blank.

    Temporary tables are session specific.
    If particular session is closed then no data will be found on your temporary table in an another session.
    My suggestion is, on "After parameter form" trigger you directly populate the GTT without using procedure.
    Hope this will help.
