Informatica Cloud has JDBC and ODBC connector available that can be used with any JDBC/ODBC driver for VSAM files. Welcome the to the Normalizer Transformation in Informatica tutorial. You can use this feature if your source is a COBOL copybook file. The VSAM Normalizer. Can any one help with any documentation or video on how to use a VSAM file as source in Informatica Cloud. There is an urgent business requirement to load.
Normalizer Transformation This post is a continuation of. Normalizer transformation type is Active & Connected. The Normalizer transformation is used in place of Source Qualifier transformations when you wish to read the data from the COBOL copy book source.
Also, a Normalizer transformation is used to convert column-wise data to row-wise data. This is similar to the transpose feature of MS Excel.
You can use this feature if your source is a COBOL copybook file or relational database table. Roll The Dice. The Normalizer transformation converts columns to rows and also generates an index for each converted row. This is type an active from the transaction which allows you to read the data from cobal files. Every Cobol source definition default associates with normalizing transformation. Use the normalize transformation to convert a single input record into multiple output records, this is known as horizontal port Normalizer Transformation Uses. Multiple record types created using redefines. Normalizer Transformation Properties Active /Passive: Normalizer Transformation is an as it creates multiple rows for each input row.
Connected/Unconnected Transformation: Normalizer Transformation is a connected Transformation. Types of ports in Normalizer Transformation Input: For reading input Data Output: For providing output Data GCID: The normalizer transformation generates thisID column for each set of multiple occurring column. It act as the undex for the instance of the multiple-occurring data.
For example, if a column occurs 3 times in a source record, the normalizer returns a value of 1,2 or 3 in the generated column ID. We can use this GCID to give some name to those value. We will see its more use in our example. GKVALUE: This port increasethe sequence value for each input row. Unlike GCID,(which was repeating itself for each set of group GKVALUE keep on increasing with each source row processed. Normalizer Transformation Components When you configure a Normalizer transformation, define the following components: Transformation tab: You can rename the transformation and add a description. Properties tab: You can specify the tracing level.
Normalizer tab: Here you define the input/output port along with occurrence. For port which receive values from multiple column we gives occurs greater than 1. Ports tab: Once port under normalizer is created, you will see input and output port for normalizer.
For nomalizer ports with occurs greater than 1, will see multiple input port but only one output port. ( see example for more details) NOTE: The Designer automatically create input /output groups once normalizer port are created under normalizer port. Configuring Normalizer Transformation Ports sociallocker id=14725 You can create input ports by copying them from another transformation or by manually creating them on the Group Ports tab.The Designer creates output ports by copying the following properties from the input ports. Port Details. Port name: Add the name of the port. Datatype, precision, and scale: Configure the datatype and set the precision and scale for each port. Default Value: In case port data is null, you can define its default value.

Normalizer transformation: Normalizer transformation is used with COBOL sources, which are often stored in a denormalized format. The OCCURS statement in a COBOL file nests multiple records of information in a single record. We can use Normalizer transformation, to break out repeated data within a record into separate records.
For each new record it creates, the Normalizer transformation generates a unique identifier. Step 1: Create the Copybook for COBOL source First Step is to get the copybook from Mainframe Team and convert that Informatica Compliant format It will look like Normally Highlighted section is provided by Mainframe team convert it into format required by format by adding line above that code (From identification to fd FNAME) and below that code (starting from working storage division). After changes save the file as.cbl file Point to be taken care while editing.cbl File You might get following error identification division. Environment division. Select Error at line 6: parse error Things to be taken care of 1.Line Select FNAME should not start before column position 12 2.Other line which have been added above and below should not start before column 9 3.All the line in structure (Highlighted above) should end with Dot. Once Cobol Source is imported successfully you can drag Normalizer source into mapping Step 2: Set Workflow Properties Properly for VSAM Source One you have successfully imported the COBOL copybook then you can create your mapping using VSAM Source.
After creating mapping you can create your workflow Please take care of following properties in session containing VSAM source In Source Advance File properties set the following options (Highlighted one) Imp: Always ask for COBOL source file to be in Binary Format, Otherwise you will face lot of problems with COMP-3 Fields Once you have set these properties you can run your workflow. COMP3 FIELDS: COBOL Comp-3 is a binary field type that puts ('packs') two digits into each byte, using a notation called Binary Coded Decimal, or BCD. This halves the storage requirements compared to a character, or COBOL 'display', field. Comp-3 is a common data type, even outside of COBOL Common issues faced while working with Comp-3 Fields: If you have created your created cobol source definition with comp-3 fields (Packed Data) but actual data in source file is not packed.So Make sure that in both the definition and source file date is in same format Check whether COMP-3 fields are signed or unsigned.
