link($DC_HOME/bin/visual,CMGR_visual) failed with error 18

If you ever installed the old version of TNPM (Proviso), you know that it was not possible to split the datachannel binaries from the data using two different locations. This was not very smart, considering that it is a common practice among many companies.

Since version 4.4.1 (I believe), this option exists and you can configure different locations for your datachannel binary files and the data files.

But, there is a catch if you use different partitions for the split (what is also the common practice...your data partition is usually remote mounted from the company data cluster).

The limitation is on the visual binary. You cannot execute it from a remote partition. If you try so, you will receive the following error on the screen:

link($DC_HOME/bin/visual,CMGR_visual) failed with error 18

This happens for all the tools that use the visual binary to bootstrap themselves (cmgr, amgr, frmi, etc...).

Fortunately, the solution is very simple:

1) Go to the $DC_HOME/bin folder
2) Open the run script used to start the tool. For instance "cmgr" for the CMGR component.
3) Go to the end of the script and add the line in red right above the last line:

cd $DC_BIN_HOME

$DC_BIN_HOME/pvexec CMGR_visual $DC_BIN_HOME/visual -nologo -noherald $DC_BIN_HOME/dc.im -headless -a CMGR "$@"

This will make sure you go back to the partition where your datachannel binaries are installed, before executing the visual command.

You have to do the same for all run scripts.

That's it.
