Hi.
We check the RT tables database every night but since some time we receive the following warning,
see below. I have tried to do about this but I have failed. Is there anyone who know how to fix this in
the “mysqltuner” script.
Use of uninitialized value $myvar{“table_cache”} in concatenation (.) or string
at /usr/bin/mysqltuner line 661 (#1)
(W uninitialized) An undefined value was used as if it were already
defined. It was interpreted as a “” or a 0, but maybe it was a mistake.
To suppress this warning assign a defined value to your variables.
To help you figure out what was undefined, perl will try to tell you the
name of the variable (if any) that was undefined. In some cases it cannot
do this, so it also tells you what operation you used the undefined value
in. Note, however, that perl optimizes your program and the operation
displayed in the warning may not necessarily appear literally in your
program. For example, “that $foo” is usually optimized into "that "
. $foo, and the warning will refer to the concatenation (.) operator,
even though there is no . in your program.
Thank you

Hi,
mysqltuner script is not written by best practical solutions. Contact
authors of the script. Try to download a new version of the script if
there is any.On Mon, Jan 16, 2012 at 20:20, thomas stridh thomas.stridh@its.uu.se wrote:
