Hi,
I have message broker 7 version.In the end of my flow the fileoutput node put the file in the linux directory as shown below.
-rw-rw---- 1 mqm mqm 3592 2012-03-28 13:33 148029_PCEXT_20120328-173021.DAT
I have created the scripts as ROOT user which will read and do some calculation on the files and after everthing is done remove the file.
Problem
I am getting a read permisions denied message ..
Could any one give me some pointer on the same. |

With those permissions only users in the others category will get read access denied. You created the scripts as root, but how do you run them?
(Hint, you don't try to read the file as root)

| You need to talk to your systems administrator about umask. |

Don't run WMB with the mqm user. Not causing this problem, but it's a problem.
Ask your UNIX sys admin what the umask command does. Stand out of arm's reach when you tell him you're running scripts as root.

No they won't.

Creating the scripts is irrelevant. The user that's running the scripts is the important point.

No, you need to run the scripts as an appropriate user. Your sys admin should be very upset if you run them as root, you should be very upset if you run them as mqm.
What you should do is have the files created with the correct permissions so that whatever user is running these scripts has the needed permissions on these files.
This is Unix 101.

No.
You NEED to TALK to your SYSTEMS ADMINISTRATOR about UMASK.
Or you need to read about the command yourself.
Or you need to read about the command 'chown' or 'chmod' and then spend a lot of time handling things yourself.
You also need to create a new user that is not the mqm user and use it to issue mqsistart, instead of using the mqm user to issue mqsistart.
Unless you're using an MQ Service to start the Broker. |

As mentioned, you need to obtain some basic Linux knowledge, here is one suggestion of a tutorial for you:
