Setting a System’s

Status

attribute controls access rights to its

rules

. This mechanism can be used to prevent accidental changes to the rules. A successful Load of the ID-Tables will automatically change the System status to

Locked

to prevent accidental changes to an implemented System.

To change the status, using the IIR Console, select

System

Status

button.

The status values in order of increasing restrictiveness are:

The following table describes the restrictions imposed by these values in terms of the ability to read, update, delete or run a System with a given status.

Status	Description	Read	Upd	Del	Run
Build	Under construction - unusable	yes	yes	yes	no
Test	Uncontrolled - any use	yes	yes	yes	yes
Production	Relaxed Production	yes	yes	no	yes
Locked	Frozen production	yes	no	no	yes
Prototype	Secured prototype - read-only use	yes	no	no	no

The System Loader cannot remove a System from the IIR Rulebase unless the System has a status that allows "deletion" (that is

build

or

test

).

If a status does not have "run" privilege the Search Server will not get access to the Rulebase and therefore searches cannot be performed.

Without the "update" privilege (that is

prototype

or

locked

), utilities such as the Table Loader cannot be run.

Prototype systems cannot be changed in any way apart from being copied. Informatica Corporation may ship sample systems with this status. Customers should not set their systems to prototype status, as they can not be altered in any way, including changing the status.

The status of a System only applies protection to the System’s rules stored in the IIR Rulebase. It does not apply protection to the IIR Identity Table and Indexes, which can still be affected by IIR utilities such as

dbinit

.
