Datastage will not start for certain values of PS1

Datastage will not start with certain values of PS1. Such as a convenient PS1 that has the
<logname>@<host>:<directory>:/<command history> \n $

as the prompt. It will stop but will not start. Seems that datastage somehow cares about the prompt value for PS1.

uv -admin -start
does not output any information in this scenario.

That is mega-weird!!! I trust you've reported it as a likely bug. I am not aware of any use the DataStage startup makes of the PS1 environment variable (nor can I conceive of any!).

I have seen the @ symbol mess up other commands. I think it is the shell. What is your hardware and OS release number?

Shell: KSH
OS: AIX 5.3 ML4 & AIX 5.2 ML8
Hardware: P5-570.

It seems to be the line feed for PS1 that causes the problems. If I remove the line feed it works. I have done this for over 5 years now and this is only product I have seen not work. That does not mean the issue here is datastage though. It very well could be a shell command, POSIX command, or AIX native command causing the issue.

As a workaround, I am resetting PS1 and PS2 in the shell script that I use to start/stop ds. This is a good workaround. I will open a case like Ray mentioned.

Thanks.
