Dollar universe inserts gibberish characters into the STDIN upon starting a job

Products

• CA Automic Dollar Universe

Issue/Introduction

Some uprocs fail on Unix/Linux nodes when launched via Dollar Universe 6.
The reason being that the STDIN contains a lot of garbage characters.

Example of Java Job launched via Dollar Universe, the output contains weird special characters in the logfile:

09:22:22.989 [main] DEBUG org.springframework.batch.core.launch.support.CommandLineJobRunner - Stdin arg: +*�

Cause

By default, Dollar Universe 6 closes the stdin of the launched processes and until version 6.4.01 this setting could not be modified.

Environment

OS: Linux/Unix

Resolution

First, be sure that the Dollar Universe node is on version 6.4.01 or superior.

There is a new node setting on Dollar Universe for Unix:U_BATCH_CLOSE_STDIN which is set by default to Y.
You can find it on the section Technical Settings -> Close standard input in batch

In case your scripts are failing because of this issue. specially on Linux/Unix with bash / ksh shells, it will be necessary to set this variable to No (N).
