macOS and Time Machine backup
After weeks of problems with Time Machine - eg the calculation of the duration of a backup of just 1 Gb must be interrupted after three days - including an incident ticket at Apple which was not able to solve the issue (btw: Thank you for your help, time and assistance, even when you not found the root cause).
Each time when we attached a disk device to initiate a backup it starts to calculate the time and never came to an end. Today we found the root cause for this behavior:
An application (Disk Drill) created a subdirectory on the harddrive and created a very huge number of small files in that directory. We analyzed this using
sudo fs_usage -w |grep -i backupd |grep -i fsctl
and recognized that a lot of files located in
where responsible for this misbehaviour. Excluding this directory from Time Machine solves the issue. Thanks to Mac O' Clock for the hints to solve this issue.

IBM Connections: wsadmin commands in batchfiles or shell-scripts
If you want to generate more complex jython scripts to be executed on IBM Connections environments you will recognize that you allways have to draw the decision on which server this should be executed. If you have an easy infrastructure you will be prompted to choose either 1 or 2.
This will work if you use wsadmin in commandline mode. But if you start to generate your own jython scripts you might want to execute them without being prompted. The most easiest way to solve this is to start your script with a variable.
The batchMode Variable predefines the serverdecision and you will no longer been prompted. Be aware that the name of the variable is case sensitive.

MacOS X High Sierra and X11 Forwarding using SSH
After installation of High Sierra we recognized that a ssh connection to other systems show up a warning:
Warning: untrusted X11 forwarding setup failed: xauth key data not generated.
This happens when you installed the latest release from XQuartz 2.7.11 during the last year or so. It seems that the installation of High Sierra replace a couple of files even if they are related and needed by other applications - like XQuartz. To solve this issue just reinstall XQuartz 2.7.11.
