  • Saving a PDF or DOC file into Oracle 9i using Developer Forms 10g

    Hi guys,
    I want to save a pdf or doc file into oracle 9i. I am using Developer 10 g. Please help me;
    1. What datatype field should be in database table to store such file.
    2. Which code should I use in Forms 10g to display open file dialog, get the name and save that into database table.
    Thanks in advance

    WEBUTIL is a library used with forms to interact with the client. With Forms10G the library comes shipped with the developer suite, for forms 9i i'm not sure, check the forms-page at otn if there is any download available. For documentation about how to do a file-upload, simply search the forum, there are lots of examples.

  • Oracle Database 11gR1 Enterprise Manager Console Cannot Display in Browser

    Folks,
    Hello. I am running Oracle Database 11gR1 with Operaing System Oracle Linux 5. I have some issues regarding EM connects with the Database Server as below:
    First, the default listener is LISTENER with standard port number 1521 and protocol TCP/IP.
    Its corresponding service naming S1 is with port 1521 and protocol TCP/IP and hostname localhost.localdomain.
    I run this listener in the following way:
    Step 1: [user@localhost bin]./lsnrctl start LISTENER (This command runs sucessfully.)
    Step 2: [user@localhost bin] ./sqlplus SYS/SYS as sysdba (This command starts sqlplus sucessfully.)
    Step 3: [user@localhost sqldeveloper] ./sqldeveloper.sh (This command invokes SQL Developer sucessfully.)
    But when start Enterprise Manager Console, it cannot connect with the Database. I do it in this way:
    [user@localhost bin] ./emctl start dbconsole
    The above command's output is:
    https://localhost.localdomain:1158/em/console/aboutApplication
    Starting Oracle Enterprise Manager 11g Database Control ... ...
    When open the link https://localhost.localdomain:1158/em/console/aboutApplication in browser, this message comes up:
    The connection to localhost.localdomain: 1158 cannot be established.
    Thus, I add Port Number 1158 into both LISTENER and Service Naming S1. I run ./emctl start dbconsole again and get this message:
    The connection to localhost.localdomain:1158 was interrupted while the page was loading.
    In order to solve the above issue, I create another listener LISTENER2 and another Service Naming S2 with Port Number 1158 and protocol TCP/IP because
    in my point of view, each listener only can have one Port Number(1521 or 1158) and its corresponding Service Naming (S1 or S2) need to have the same Port Number and Protocol (TCP/IP).
    But when I run [user@localhost bin]./lsnrctl start LISTENER2, this message comes up: the listener supports no service.
    From the message, it seems that LISTENER2 cannot work with its corresponding Service Naming S2 with Port 1158.
    EM with Port 1158 cannot display in Browser.
    My questions are :
    First, Is there any relationship needed to be established between listener(LISTENER2) and Service Naming(S2) in order to display EM in Browser ?
    Second, how do folks display EM in browser ?
    Thanks.

    Folks,
    Hello. Thanks a lot for replying. I do the following command: [user@localhost bin]$ wget http://localhost.localdomain:1158/em

    Please advise?
    Thanks
    Dave

    Hi,
    Perhaps it is not clear about what are the invalid characters its is showing.....is it showing asterisks.....Well if it does show anything like that then all u have to do is go and change the dimensions of the particular field in which it is showing such characters.......i mean u r to change the rdf file in Reports Builder.....and try changing the length and width by dragging the edges of the particular field and then save it and after that convert it into .xml and .rep files and then run it.

  • Storing JSON string into Oracle table

    Hi,
    What is appropriate way to store JSON string into Oracle table?
    Regards
    Peter

    If JSON becomes more popular, ORACLE might write data cartridge extension for JSONDB (in the same way as XMLDB).
    Till then CLOB and NCLOB is your best choice, and leave the parsing in your application layer.

  • Issues du read XML into Oracle

    Hello all,
    I try to insret XML data into Oracle, and I looked on forum for tips. I found (I think) the way to do it, but I have an error :
    Here is what I did : I created a table of XMLType (OK) :
    CREATE TABLE XML_TAB ( xmlval XMLType);
    Then I insert data directly (OK):
    INSERT INTO XML_TAB VALUES (
    xmltype('&lt;?xml version="1.0"?&gt;
    &lt;EMP&gt;
    &lt;EMPNO&gt;221&lt;/EMPNO&gt;
    &lt;ENAME&gt;John&lt;/ENAME&gt;
    &lt;/EMP&gt;'));
    Now, I want to import directly from a XML file. I try this :
    INSERT INTO Xml_tab
    VALUES
    xmltype(bfilename('xml_dir','essai2.xml'),nls_charset_id('AL32UTF8'))
    it fails with ORA-06553: PLS-306: num&eacute;ro ou types d'arguments erron&eacute;s dans appel &agrave; 'XMLTYPE' (xml_dir is setup)
    or this :
    INSERT INTO Xml_tab

    it fails with ORA-06553: PLS-307: trop de d&eacute;clarations de 'XMLTYPE' correspondent &agrave; cet appel
    I try with Oracle 9i.
    Did I miss something ?
    I'm not far to succeed what I want to do. Thank's a lot for your help.
    Antoine

    Hello,
    Thanks for you answer. Oracle version is 9.2.0.4.0.
    Thanks also for the BFILENAME information. My problem remains that if I try to read by entering directly the filename, I have the PLS307 error.
    I will check the XMLDB FAQ, but I have seen several documentation, and process is always the same, as I do...except for the error.
    I will also try in 10g, to see if it works better.

  • Best Practice to fetch SQL Server data and Insert into Oracle Tables

    Hello,
    I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
    We do not have any database dblinks from oracle to sqlserver and vice versa.
    Any help is highly appreciable?
    Thanks

    Well, that's easy:
    use a TimerTask to do the following every half an hour:
    - open a connection to sql server
    - open two connections to the oracle databases
    - for each row you read from the sql server, do the inserts into the oracle databases
    - commit
    - close all connections

  • Loading shapefiles into Oracle Spatial

    Fellow Oracle Spatiallers!
    Currently we edit Oracle Spatial data by checking data out into a shapefile,
    making our changes off-line, and reloading the shapefile back into Oracle.
    Instead of using the Oracle Spatial supplied tool, we decided to purchase
    a utility called the "Spatial Loader" from a company called Geometry Pty Ltd
    (http://www.geometryit.com). There are a number of reasons why we decided to
    go that way which might become evident from the command line parameters of
    this utility:
    Usage: Shp2Spt [Arguments] [Options]
    OR
    Usage: Java com.geometryit.spatialloader.oracle.AdvancedJavaSpatialTranslator [Arguments] [Options]
    [Arguments] must specify these values:
    -o create
    type of operation to perform
    create creates a new table, must not exist already
    recreate creates a new table, may exist already
    init drops existing table, creates a new one
    append appends data onto existing table
    -f <shape_file>
    the shape file or project to translate
    -l <table,column>
    target table and column for the geometry data
    -D <database>
    target database name
    -u <username>
    username for RDBMS
    -p <password>
    password for RDBMS
    [Options] values are not necessarily required:
    -s <server_name>
    name of server with database
    -port <port_number>
    the port to connect to on the server
    -ufi <column_name>
    specify the name of the UFI field (unique ID)
    -seq <sequence_name>
    specify the sequence to use for the spatial data unique IDs
    -a none
    attributes mode
    none no attributes will be transferred
    all all attribtues will be transfered as found
    file= file containing lines of the form:
    <shape_attribute><space/tab><rdbms_column>
    where
    <shape_attribute> selects the column to be output
    <rdbms_column> name of the column in RDBMS
    -srid <id>
    specify the Spatial Reference ID for the spatial data
    (this must be set to use Spatial Reference Transformations)
    -i [<level>] or -i rtree
    create an index for the generated table
    the <level> parameter is an optional integer
    representing the depth of the quadtree created

    display this help message
    The main things I like about this tool are:
    1. One step (no conversion to sqlloader form followed by a call to the sqlloader).
    2. The ability to round the coordinates of the shapes in the shapefile by applying
    the XY tolerance values held in the SDO_GEOM_METADATA table.
    This is quite important because our editing package - due to double/single precision
    issues - can actually move coordinates but those movements are sub the precision of
    the actual data. By rounding to the nominate precision we can detect situations where
    no actual change to the shape (and its attributes) was made and thus not create superfluous
    revisions within the database.
    3. It will correctly re-wind the coordinates of the outer/inner shells of polygons. This is
    important as ESRI shapefiles are agnostic on the winding order: an outer shell coordinates
    can be listed in either clockwise or anti-clockwise order.
    4. You can specify the primary key (UFI) column (numeric) and an Oracle Sequence number such
    that each new shape loaded can have its UFI assigned from that sequence.
    Because of this flexibility, and the excellent support (it is a purchasable product) from the
    developers, I can heartily recommend this loader to fellow Spatiallers. It is worth every
    penny I spent on it. Try the free version on their website and if, like me, you like it,
    purchase it!
    regards
    Simon

    Hi Shuan,
    As part of the zip file created for the next training course to be posted for Oracle Spatial on OTN (within the next few weeks) there is a free (unsupported, undocumented) version of a shape to sdo converter. This should work, but it is unsupported. It will create a layer that then needs to be migrated into 8.1.6 format.
    If you need it quite soon send email to [email protected] and I can get it to you.
    Hope this helps,
    dan
