# dpkg -i mysql-apt-config_0.8.10-1_all.deb 

Vormals nicht ausgewähltes Paket mysql-apt-config wird gewählt.

systemd: systemd-notify not working for non-root-users

Sometimes you have to write your own startup scripts. Recent linux distributions require systemd scripts. This is not really a problem except you have to fulfill the following requirements:
  • Run the service as a non-root-user
  • The service has a startup phase and you want to start the next startup scripts after this startup phase
So the systemd-script has to look like this:
# cat /lib/systemd/system/TEST.service
[Unit]
Description=MyTestSystemdConfiguration

[Service]
User=schroff
Type=notify
ExecStart=/home/schroff/bin/test.sh
NotifyAccess=all
The service startup scripts have to look like this:
$ cat /home/schroff/bin/test.sh
#!/bin/bash

echo Starting serivce
sleep 10
#Starting your services
echo Services started

/bin/systemd-notify --ready
echo Notify done

while test 1 do
  sleep 600
done
#keep this scripts running, as long your service runs
In the startup phase you will get the following:
schroff@zerberus:~/bin$ systemctl status TEST.service
● TEST.service - MyTestSystemdConfiguration
   Loaded: loaded (/lib/systemd/system/TEST.service; static; vendor preset: enabled)
   Active: activating (start) since 19:39:27 CET; 7s ago
 Main PID: 17390 (test.sh)
    Tasks: 2 (limit: 4915)
   Memory: 532.0K::
      CPU: 7ms
   CGroup: /system.slice/TEST.service
           ├─17390 /bin/bash /home/schroff/bin/test.sh
           └─17395 sleep 10

19:39:27 zerberus systemd[1]: Starting MyTestSystemdConfiguration...
19:39:27 zerberus test.sh[17390]: Starting serivce
And after the startup phase this is the output (if there were no errors):
schroff@zerberus:~/bin$ systemctl status TEST.service
● TEST.service - MyTestSystemdConfiguration
   Loaded: loaded (/lib/systemd/system/TEST.service; static; vendor preset: enabled)
   Active: active (running) since 19:38:38 CET; 3s ago
 Main PID: 17242 (test.sh)
    Tasks: 2 (limit: 4915)
   Memory: 932.0K
      CPU: 9ms
   CGroup: /system.slice/TEST.service
           ├─17242 /bin/bash /home/schroff/bin/test.sh
           └─17259 sleep 600

19:38:28 zerberus systemd[1]: Starting MyTestSystemdConfiguration...
19:38:28 zerberus test.sh[17242]: Starting serivce
19:38:38 zerberus test.sh[17242]: Services started
19:38:38 zerberus systemd[1]: Started MyTestSystemdConfiguration.
19:38:38 zerberus test.sh[17242]: Notify done
But sometime you will get:
# systemctl restart TEST.service
Job for TEST.service failed because a timeout was exceeded.
See "systemctl  status TEST.service" and "journalctl  -xe" for details.
19:44:46 zerberus systemd[1]: TEST.service: Start operation timed out. Terminating.
19:44:46 zerberus systemd[1]: Failed to start MyTestSystemdConfiguration.
-- Subject: Unit TEST.service has failed
-- Defined-By: systemd
-- Support: http://www.ubuntu.com/support
--
-- Unit TEST.service has failed.
--
-- The result is failed.
19:44:46 zerberus systemd[1]: TEST.service: Unit entered failed state.
19:44:46 zerberus systemd[1]: TEST.service: Failed with result 'timeout'.

Note that this will happen after 600s (default). You can change this with the parameter (systemd configuration, see manpage systemd.service)
TimeoutSec
But changing this Parameter will not help, because systemd status will never enter the state "active (running)".

The problem is systemd-notify doesn't work, since it lives too short (Redhat Bugzilla).


A workaround is described in that bug entry:
Instead of
systemd-notify --ready
use

Oracle SOA Suite 12c : Audit Levels (Off, Production, Development)

Inside the Enterprise Manager (URL: http://yourhost:7001/em) you can configure SOA Suite Audit Levels:

Choose "Common Properties"

Click on "Change Profile"
The oracle documentation shows the following:



  • Off:
    No business flow instance tracking and payload tracking information is collected. Drilling down into a flow shows the components and their status. Using this setting limits database growth, and also helps reduce latency and improve throughput.
  • Production:
    Flow and audit event information is collected and stored in the database. Drilling down into a flow provides the flow trace. The flow trace shows the exact sequence of component interaction, and also shows component statuses. Drilling down into a BPEL instance shows the execution of BPEL activities, and their statuses.
    As the flow-trace audit trail may not be required for all composites, you may want to set the audit level to Off at the SOA Infrastructure level, and set the audit level to Production for the required composites
  • Development:
    This option collects payload details in addition to flow and audit events. This setting is not recommended for a production environment, as it will impact performance and result in rapid database growth. This level is useful largely for testing and debugging purposes only.

Ubuntu / Linux: WLAN connections fails with "denied authentication (status 17)"

During holidays i was not able to connect my laptop to the WLAN.
The /var/log/syslog showed the following:

Hmmm.
STATUS 17
What the hell does this error code tell me?

The explanation was quite easy: The WLAN was provided by a tablet via tethering. And Android limits the number of devices in such a WLAN to 5.
After removing one of the other devices everything worked fine...
