db2 user

Overview

This resource allows you to manage a DB2 user. Here is an example on how to use this:

db2_user { 'db2inst1/MYDB/MYUSER':
  ensure   => 'present',
  grants   => ['DBADM', 'SECADM', 'DATAACCESS', 'ACCESSCTRL'],
  roles    => ['SYSTS_ADM', 'SYSTS_MGR', 'SYSDEBUG', 'SYSDEBUGPRIVATE'],
}

This will ensure a DB2 user named MYUSER in database MYDB on instance db2inst1. This type is mainly available to manage grants and roles. It will not create the os user’s needed fro this.

Attributes

The name of the database.

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)

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.

Back to overview of db2_user

granted

The grants you want to make sure are granted to the db2_user, db2_group, or db2_role. It is different from the grants` property in the sense that this is not a full list of the rights, but just the rights that are granted to the user

Here is an example with an db2_user:

db2_user {'db2inst1/MYDB/my_user':
  ...
  granted => ['CREATETAB'],
  ...
}

Here is an example with an db2_role:

db2_role {'db2inst1/MYDB/my_role':
  ...
  granted => ['CREATETAB'],
  ...
}

**WARNING**

When you us both the `grants` and `granted` property, Puppet will give you a warning about conflicting values. In the end it **WILL** ensure
that the rights specified for the `revoked` property are removed. This way ensuring the most secure configuration.

grants

grants for this user or role.

All the grants this resource has. Here is an example on how to use this on an db2_user:

db2_user { 'my_user@sid':
  ...
  grants => ['UNLIMITED TABLESPACE', 'CREATE PUBLIC SYNONYM'].
  ...
}

Here is an example on how to use this on an db2_role:

db2_role { 'my_role@sid':
  ...
  grants => ['UNLIMITED TABLESPACE', 'CREATE PUBLIC SYNONYM'].

revoked

The grants you want to make sure are revoked from the db2_user, db2_group or db2_role. It is different from the grants property in the sense that this is not a full list of the rights, but just the rights that are NOT granted to the user

Here is an example when using db2_user:

db2_user {'db2inst1/MYDB/my_user':
  ...
  revoked => ['CREATETAB'],
}

Here is an example when using db2_role:

db2_role {'db2inst1/MYDB/my_role':
  ...
  revoked => ['CREATETAB'],
}

WARNING

When you us both the grants and revoked property, Puppet will give you a warning about conflicting values. In the end it WILL ensure that the rights specified for the revoked property are removed. This way ensuring the most secure configuration.
