DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
| Problem description: | |
In this example 'db2look' was used as the client.
After interrupting 'db2look' using CTRL-C we can see that the
'db2look' process is gone as it does not appear in the 'ps'
output
anymore.
$ ps -ef | grep db2look | grep -v grep
However, db2look still appears in the list of applications.
