When inheriting another class and trying to override a parameter for a define,
the new value does not get set.
What I am doing:
oracle_db/manifests/init.pp
<pre>
class oracle_db {
etc_sysctl_conf { 'kernel.shmall':
value => '1',
}
}
</pre>
oracle_db/manifests/etc_sysctl_conf.pp
<pre>
define oracle_db::etc_sysctl_conf ( $attr = $name, $value ) {
notify{"${attr}:${value}": }
}
</pre>
oracle_db/manifests/hugepages.pp
<pre>
class oracle_db::hugepages inherits oracle_db {
Oracle_db::Etc_sysctl_conf['kernel.shmall'] {
value => '2',
}
oracle_db::etc_sysctl_conf { "vm.nr_hugepages":
value => '3';
}
}
</pre>
So I am trying to override oracle_db::etc_sysctl_conf['kernel.shmall'] resource
in oracle_db::hugepages to change value parameter from 1 (set in oracle_db) to
2.
I then have oracle_db and oracle_db::hugepages assigned to the system via an
ENC. I've also tested with just having oracle_db::hugepages assigned via ENC.
The results I get are:
<pre>
notice: kernel.shmall:1
notice:
/Stage[main]/Oracle_db/Oracle_db::Etc_sysctl_conf[kernel.shmall]/Notify[kernel.shmall:1]/message:
defined 'message' as 'kernel.shmall:1'
notice: vm.nr_hugepages:3
notice:
/Stage[main]/Oracle_db::Hugepages/Oracle_db::Etc_sysctl_conf[vm.nr_hugepages]/Notify[vm.nr_hugepages:3]/message:
defined 'message' as 'vm.nr_hugepages:3'
</pre>
And what I would expect is for kernel.shmall to have a value of 2 instead (the
following is hand-edited to show what I would expect):
<pre>
notice: kernel.shmall:2
notice:
/Stage[main]/Oracle_db/Oracle_db::Etc_sysctl_conf[kernel.shmall]/Notify[kernel.shmall:2]/message:
defined 'message' as 'kernel.shmall:2'
notice: vm.nr_hugepages:3
notice:
/Stage[main]/Oracle_db::Hugepages/Oracle_db::Etc_sysctl_conf[vm.nr_hugepages]/Notify[vm.nr_hugepages:3]/message:
defined 'message' as 'vm.nr_hugepages:3'
</pre>
Complete output from a run:
