Exceptions in Informatica – 2

Let us see few more strange exceptions in Informatica

1. Sometimes the Session fails with the below error message.

"FATAL ERROR : Caught a fatal signal/exception

FATAL ERROR : Aborting the DTM process due to fatal signal/exception."

There might be several reasons for this. One possible reason could be the way the function SUBSTR is used in the mappings, like the length argument of the SUBSTR function being specified incorrectly.

Example:

IIF(SUBSTR(MOBILE_NUMBER, 1, 1) = ‘9′,

SUBSTR(MOBILE_NUMBER, 2, 24),

MOBILE_NUMBER)

In this example MOBILE_NUMBER is a variable port and is 24 characters long.

When the field itself is 24 char long, the SUBSTR starts at position 2 and go for a length of 24 which is the 25th character.

To solve this, correct the length option so that it does not go beyond the length of the field or avoid using the length option to return the entire string starting with the start value.

Example:

In this example modify the expression as follows:

IIF(SUBSTR(MOBILE_NUMBER, 1, 1) = ‘9

′,

SUBSTR(MOBILE_NUMBER, 2, 23),

MOBILE_NUMBER)

OR

IIF(SUBSTR(MOBILE_NUMBER, 1, 1) = ‘9

′,

SUBSTR(MOBILE_NUMBER, 2),

MOBILE_NUMBER).

2. The following error can occur at times when a session is run

"TE_11015 Error in xxx: No matching input port found for output port OUTPUT_PORT TM_6006 Error initializing DTM for session…"

Where xxx is a Transformation Name.

This error will occur when there is corruption in the transformation.

To resolve this do one of the following: * Recreate the transformation in the mapping having this error.

Three times you get the below problems,

1. When opening designer, you get "Exception access violation", "Unexpected condition detected".

2. Unable to see the navigator window, output window or the overview window in designer even after toggling it on.

3. Toolbars or checkboxes are not showing up correctly.

These are all indications that the pmdesign.ini file might be corrupted. To solve this, following steps need to be followed.

1. Close Informatica Designer

2. Rename the pmdesign.ini (in c:\winnt\system32 or c:\windows\system).

3. Re-open the designer.
