Diary of an Informatica 9.1.6 HF1 Install

Here are some notes on an Informatica PowerCenter 9.6.1 64 bit server install.  This also includes the setup of the Informatica Cloud Secure Agent (64)

Most of the install went smooth.  However I want to list some of the problems I encountered.

Use A Mapping Parameter in an SAP ABAP Mapping

There are two areas for logic, the Dynamic Filter and the Static Filter. Use Static Filter and you don't have to create an ABAP block.


VBScript to Convert Excel to CSV

Using Excel files as the source for Informatica mappings can be more trouble than it's worth. You have to setup a connection and name a range in the Excel document which can be difficult to maintain. I much prefer to read text or CSV files, they're simpler to work with and less error prone. I created this VB script for the purpose of converting Excel to CSV.

Querying the Repository

Here are some SQL scripts you can use to query the repository. Most of these I got from an Informatica employee, others I put together. Use them as a base to create your own queries or reports.

One word of caution, use a profile with READ ONLY permission to access the repository and NEVER update the repository using SQL unless advised to do so by Informatica support.

Using pmrep to import an Informatica folder

Here’s the companion script for the “Using pmrep to export an Informatica folder” article. Use this script to import objects into PowerCenter.

One use for scripting an import would be to schedule it during off hours, for example moving development code to production during off hours. You may also need to export some objects, then do a "mass change" or Find/Replace on the XML file, then export them back in (for example, export all sessions, find/replace a connection).

Managing Connections using Parameter Files

Try this tip for managing PowerCenter connections.

Parametrize connections and use one parameter file to define them. Use the one parameter file in all your workflows. This will bring consistency to development and make it easy when connection changes are required.

VBScript to Combine Multiple XLS Files into a Single File

Here's a companion tip to the "VBScript to convert CSV to XLS" post.

This script will combine two Excels files into one workbook. The files will be treated as separate worksheets inside the workbook. The worksheet names will be the same as the file names.

You may find this useful when an Inforamtica process outputs multiple flat files and you have converted them into native Excel format but only wish to present one file to the end user (or for archiving or reporting purposes).

The Transaction Control

Here is a sample mapping to illustrate how the Transaction Control transformation can dynamically create multiple flat file outputs, each with a unique name and data set.

The mapping reads a source table whose key is “Group Id”, and outputs a separate target file for each Group Id data set. The file names are also generated dynamically based on the Group Id.
