Connect To Oracle With A Workflow

Revision as of 12:33, 11 February 2015 by KNO (Talk | contribs)

Prior to connecting to an Oracle database it is necessary to configure the connection to the server on your local environment. UBIK® uses OLEDB to connecti to Oracle via TNS (Transparent Network Substrate).

[edit]

Instructions

  1. After the installation of the Oracle client you have to configure the Oracle server in the TNS Names:
    1. Locate the file tnsnames.ora in the directory [ORACLESOFTWARE]\network\admin\
    2. Configure the connection and call it (like in this example TESTDB):

TESTDB= 

(DESCRIPTION =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(Host =AUGTESTORACLE.cloudapp.net)(Port = 1521))
  )
(CONNECT_DATA =
  (SERVICE_NAME = UBIKTEST)
)

)

  1. Use the [[CreateOLEOracleScope (Activity)}} activity to configure the connection via the arguments:
    • the Oracle database DataSource
    • the InitialCatalog
    • UserName and Password
  2. Use the CreateOLETableScope (Activity) activity or a CreateOLEQueryScope (Activity) to define the table you want to fetch data from. Set the tablename in the DisplayName argument.
  3. Use a ForEach<DataRow> activity to iterate over the records fetched from the table.
  4. A column of the recordset (table) can be accessed by its index.
