Docker-CE: initial configuration

After installing docker to a ubuntu server i was keen what kind of processes and files are there.
# ps x|grep docker
 5852 ?        Ssl    0:05 /usr/bin/dockerd -H fd://
 5867 ?        Ssl    0:04 docker-containerd --config /var/run/docker/containerd/containerd.toml
So the inital configuration is not stored in /etc.

The configuration file looks like this:
# cat /var/run/docker/containerd/containerd.toml
root = "/var/lib/docker/containerd/daemon"
state = "/var/run/docker/containerd/daemon"
subreaper = false
oom_score = -500

Oracle SOA Suite 12c: database configuration

After the running the rcu i was keen what was created inside the database. The installation showed some additional tablespaces:

Oracle SOA Suite 12c: rcu from a remote host / database configuration

First step is to configure the database on your Oracle Linux server which hosts your database:
[root@localhost admin]# firewall-cmd --permanent --zone public --add-port=1521/tcp
success
Then run the rcu:

2017 DOAG – Thanks to My Friends


I mentioned in my last post that I had been accepted by the DOAG and had to break my commitment as I have extended my trip to Australia to include New Zealand.

I didn't like to let down the DOAG, and I had two presentations. One is a customer case study on DHL, who are owned by Deutsche Post, so lots of local interest, and then my 'Extending HCM with VBCS'.
