Hi all,
What does it mean to create a symbolic link to /usr/bin/true
I am trying to install CSD12 on MQ manager 5.3 and i am getting an error saying that Failed to clean System V IPC resources. In order to solve this error, i have to go through some steps as advised by IBM. The IBM site says that i must create a symbolic link to /usr/bin/true and then rename amqiclen. I don't understand what it means by symbolic link or how to create it. Please advise.
Thank you all... |

Hi
yes, it happens sometimes
Step 1: copy the amqiclen , use cp -p option
Step 2: ln -s /usr/bin/true /opt/mqm/bin/amqiclen
Step 3: Start installing
after the installation it will automatically go off.
This will help you
Thanks and Regards
Gaythri

Simplistically:
A symlink is a UNIX construct - a fake directory that points to another location. Like a Windows shortcut but far more sophisticated & useful. Created with the ln command. Many possible options.
Less simplistically:
Ask your UNIX admin to explain it, with diagrams.

I get the following error when i try to create a symbolic link. Please see below:
$ ln -s /usr/bin/true /opt/mqm/bin/amqiclen
ln: cannot create /opt/mqm/bin/amqiclen: File exists
Why is it so? Am i missing something here...
I actually copied the amqiclen from /opt/mqm/bin directory using cp -p command and saved it in /var/mqm (i guess i can copy it anywhere, am i correct?)
then i tried to run the above command and i receive this error...
please advise
thanks |

Hey
Sorry one option i forgot to add
amqiclen file has to be removed before converting it to a link to /usr/bin/true
Please do the above one and let us know the status
Thanks and Regards

You just need it somewhere safe in case the installer doesn't put it back for some bizarre reason and you need to copy it back yourself.

| Actually, a symbolic link is a file that contains the real path to a file. Think of it as an alias to the real path to a file. |
