Hi all,
I am trying to use the FileOutput Node (WMB ver 7.0.0.3) to create a file and FTP it to an AIX server (ver 6.1).
The flow works fine when I run it on my own machine (Windows). Here I am FTPing from a Windows machine to an AIX server (say, server B)
But when I deploy the same flow onto another AIX server (say, server A) the FileOutput Node throws an exception and the file is not being sent to server B.
Even the local file, on server A, is absent, though I have set 'Retain local file after transfer' to checked (But the mqsitransit folder shows that it has been modified at the time that the message was sent).
Some additional info:
I have set the Security Identity on both (Windows and AIX server A).
I am setting Record definition to 'Record is Whole File' (So the file is completed without having to wire in the Finish File terminal)
I am not able to use FTP (as a client, from the command line) on AIX server A when logged in as the user that the broker is running under.
I feel that this is indeed the reason for the failure, but the error message doesn't say anything on those lines.
Is the below error due to the fact that the broker's user is not able to use FTP or it is it something else?
Here is the Error Info:

On a different note, why is it that I am not able to use FTP on the AIX server (A) while logged in as a non-root user?
(I am able to do so on server B using a non-root user.) |

1. On AIX, you should not log in as the mqbrkrs user. You should log in as you, then sudo to the mqbrkrs user to execute mqsi commands.
2. On AIX, the service user id being used to run WMB should be a member of mqbrkrs as its primary group.
3. Any directories used should have appropriate permissions set to allow the broker service Id read/write access. Sometimes the easiest way to accomplish this is by having the mqbrkrs Id create a subdirectory underneath /var/mqsi or /var/mqsi/common for file transfer use. Using other pathing can be problematic with overzealous sys-admins.

After over 3 months and 3 GB of logs, turns out the problem was with blotched permissions on the /tmp folder...
It didn't have write permissions for other users causing the JVM to throw up the above error...

As always with file nodes.
Just run the same FTP or SFTP operation outside the broker (but with the broker id) to debug any environment issues before worrying about getting the flow to work. |
