ora init param

Overview

This resource allows you to manage Oracle parameters.

this type allows you to manage your init.ora parameters. You can manage your spfile parameters and your memory parameters. First the easy variant where you want to change an spfile parameter on your current sid for your current sid.

ora_init_param{'SPFILE/PARAMETER':
  ensure  => present,
  value   => 'the_value'
}

To manage the same parameter only the in-memory one, use:

init_param{'MEMORY/PARAMETER':
  ensure  => present,
  value   => 'the_value'
}

If you are running RAC and need to specify a parameter for an other instance, you can specify the instance as well.

init_param{'MEMORY/PARAMETER:INSTANCE':
  ensure  => present,
  value   => 'the_value'
}

Having more then one sid running on your node and you want to specify the sid you want to use, use @SID at the end.

init_param{'MEMORY/PARAMETER:INSTANCE@SID':
  ensure  => present,
  value   => 'the_value'
}

Attributes

disable_corrective_change

Disable the modification of a resource when Puppet decides it is a corrective change.

(requires easy_type V2.11.0 or higher)

When using a Puppet Server, Puppet knows about adaptive and corrective changes. A corrective change is when Puppet notices that the resource has changed, but the catalog has not changed. This can occur for example, when a user, by accident or willingly, changed something on the system that Puppet is managing. The normal Puppet process then repairs this and puts the resource back in the state as defined in the catalog. This process is precisely what you want most of the time, but not always. This can sometimes also occur when a hardware or network error occurs. Then Puppet cannot correctly determine the current state of the system and thinks the resource is changed, while in fact, it is not. Letting Puppet recreate remove or change the resource in these cases, is NOT wat you want.

Using the disable_corrective_change parameter, you can disable corrective changes on the current resource.

Here is an example of this:

crucial_resource {'be_carefull':
  ...
  disable_corrective_change => true,
  ...
}

When a corrective ensure does happen on the resource Puppet will not modify the resource and signal an error:

    Error: Corrective change present requested by catalog, but disabled by parameter disable_corrective_change
    Error: /Stage[main]/Main/Crucial_resource[be_carefull]/parameter: change from '10' to '20' failed: Corrective change present requested by catalog, but disabled by parameter disable_corrective_change. (corrective)

disable_corrective_ensure

Disable the creation or removal of a resource when Puppet decides is a corrective change.

(requires easy_type V2.11.0 or higher)

Using the disable_corrective_ensure parameter, you can disable corrective ensure present or ensure absent actions on the current resource.

Here is an example of this:

crucial_resource {'be_carefull':
  ensure                    => 'present',
  ...
  disable_corrective_ensure => true,
  ...
}

When a corrective ensure does happen on the resource Puppet will not create or remove the resource and signal an error:

    Error: Corrective ensure present requested by catalog, but disabled by parameter disable_corrective_ensure.
    Error: /Stage[main]/Main/Crucial_resource[be_carefull]/ensure: change from 'absent' to 'present' failed: Corrective ensure present requested by catalog, but disabled by parameter disable_corrective_ensure. (corrective)

ensure

The basic property that the resource should be in.

Valid values are present, absent.

for_sid

name

The parameter name.

parameter_name

The parameter name.

provider

The specific backend to use for this ora_init_param resource. You will seldom need to specify this — Puppet will usually discover the appropriate provider for your platform.Available providers are:

scope

The scope of the change.

Valid values are SPFILE, MEMORY, spfile, memory.

Back to overview of ora_init_param

sid

SID to connect to.

All types have a name like resource@sid. The sid is optional. If you don’t specify the sid, the type will use the database from the /etc/ora_setting.yaml with the property default set to true. We advise you to either use @sid in all your manifests or leave it empty everywhere.

Back to overview of ora_init_param

value

The value or values of the parameter.

You can use either a single value or an Array value. Although not strictly required, we reccomend that you alsways use quoted values. Also when using nummeric or boolean values.

An example using a boolean value:

ora_init_param { ....:
  ...
  value  => 'FALSE',
}

Here an example using an array of values:

ora_init_param { ....:
  ...
  value  => ['RECODG', 'BACKUPDG', 'DATADG'],
}

ora_init_param { ...:
  ...
  value  => '1',
}
