Graceful stop of container is not possible due "workaround"

[profhccaesar]

The last lines of runOracle.sh are:

# TODO workaround
tail -f /dev/null

This "workaround" (work around what) prevents a graceful shutdown of the container because the root process never ends - although the database was already shut down. T. m.,

docker stop -t 200 oracle-xe

takes always 200 seconds, even if the database shutdown only needs 30 seconds or so. After the timeout of 200s the container is killed.

This means that also a shutdown of docker (and therefore the complete workstation) takes at least 200 sec - at least if the timeout was defined by docker run --stop-timeout 200 ...).

Removing the tail-Statement solves that problem. Seems to bring no other problems.
