How to get the script output from a command task in Informatica BDM?
If a command task is executing a shell script, you will get the exit code, standard output and standard error from the script in the Command task output. You can assign these fields to a workflow variable in the "Command Task Output" and use later in the workflow.
Let's consider a shell script which will look for an Inbound file in a source location, If the file found script will display the file name and complete with an exit code 0. You are calling this script from a command task, after the execution you will get the outputs like below in the command task.
v_cmt_01_exitcode = 0
v_cmt_01_stdout = file_name.txt
v_cmt_01_stderr =
If the script failed due to an unknown Issue
v_cmt_01_exitcode = 1
v_cmt_01_stdout =
v_cmt_01_stderr = "error message"
If the script failed due to a known Issue (Assuming Script is coded such a way to exit with code 1 and with a proper error message)
v_cmt_01_exitcode = 1
v_cmt_01_stdout = "File not found in the source location"
v_cmt_01_stderr =
If you want to display the workflow variable for debugging purpose, use a notification task and send the variables to you email for validation.
