Description Jan Pazdziora 2007-12-21 04:52:40 EST
Description of problem:

The check-oracle-space-usage.sh calls

   su - oracle -c "db-control report"

and then processes its output. However, it seems some users have settings in
/etc/profile or other logon files that lead to some extra output being returned
by that su command. That in turns breaks our postprocessing

   awk '{print $5}'|sed '1d'| sed 's/%//g'

and leads to errors since non-numeric data appears on the output.

Version-Release number of selected component (if applicable):


How reproducible:

Deterministic if you have something in /etc/profile.

Steps to Reproduce:
1. Add "echo Test" to your /etc/profile.
2. Run /etc/cron.daily/check-oracle-space-usage.sh
Actual results:

# /etc/cron.daily/check-oracle-space-usage.sh
/etc/cron.daily/check-oracle-space-usage.sh: line 42: [: Use: integer expression

Expected results:

No error, the script should be robust enough to work even in this case.

Additional info:

See the thread at

The post at
suggests using

   awk '/[0-9]%$/ {gsub("%", ""); print $NF}'

Which seems good enough.

BTW -- don't forget to remove that "echo Test" from your /etc/profile when
you're done with this bug.

Colin C.Coe noted in private email that it might be worth only processing those
lines ending with % sign that follow a line with "Tablespaces". That way, if
user's have some mess in their .bash_profiles ...

A cow orker has his .bash_profile output how full (in %) of the shared
/scratch.  The original awk DoesTheWrongThing(tm) if there is a line of
output the ends with a number and % sign as the last things on the line
before the actual output of 'db-control report'.  The below awk doesn't
print anything unless it has already seen a line starting with

... we'll only process the correct lines.

Fixed in Spacewalk repo, commit a091b99a1121ba2bcaf1415e0dd2eb47beed39a2.

I've ended up calling runuser without -, so that /etc/profile and ~/.bash_profile are not read at all.
