<p>The Retrieve Authorization List Information (QSYRTVAI) API returns to
|
||
|
the caller
|
||
|
information about the number of authorization list entries that are in use
|
||
|
for the specified authorization list.
|
||
|
The returned information can be use to determine how full an authorization list
|
||
|
is.
|
||
|
</p>
|
||
|
|
||
|
<p>The normal view of an authorization list (AUTL) is that it is a single
|
||
|
object (structure) with the capacity to secure 2,097,104
|
||
|
objects. However, to successfully manage the fullness of an AUTL, a more comprehensive
|
||
|
view of an AUTL is required.</p>
|
||
|
|
||
|
<p>When an object is secured by an AUTL, each piece of the object
|
||
|
may have to be individually
|
||
|
secured by the AUTL. This means that when an object is secured by an AUTL, multiple
|
||
|
entries in the AUTL may be used by the system to secure all of the parts
|
||
|
of the object. For example, when a database file with multiple members is secured by
|
||
|
an AUTL,
|
||
|
multiple entries in the AUTL will be used.
|
||
|
Because of this, using commands like DSPAUTLOBJ (Display
|
||
|
Authorization List Objects) and APIs like QSYLATLO (List Authorization List
|
||
|
Objects), is not an effective way to determine whether an AUTL is becoming full.
|
||
|
</p>
|
||
|
|
||
|
<p>In addition, the first
|
||
|
time an AUTL is used to secure an object that resides in an independent
|
||
|
auxiliary storage pool (ASP),
|
||
|
the system creates an internal structure in the independent
|
||
|
ASP that is transparently
|
||
|
tied to the AUTL object. This internal structure is called an authorization
|
||
|
list extension. The authorization list extension has entries just like the AUTL
|
||
|
but these entries can only be used to secure objects that reside in the independent
|
||
|
ASP.
|
||
|
An authorization list extension also has a maximum of 2,097,104 entries. These
|
||
|
entries are in addition to the 2,097,104 entries in the base AUTL which are
|
||
|
used to secure objects in the system and basic user auxiliary storage pools
|
||
|
(*SYSBAS). The system can have a maximum of 223 independent
|
||
|
ASPs; therefore, the theoretical combined
|
||
|
limit for an AUTL and its extensions is 469,751,296 entries
|
||
|
(224 multiplied by 2,097,104).
|
||
|
</p>
|
||
|
|
||
|
<p>If an attempt is made to secure an object that resides in an independent
|
||
|
ASP with an
|
||
|
AUTL but all of the entries in the authorization list extension for the object's
|
||
|
independent ASP have
|
||
|
been used; an MCH2804 exception will occur indicating that the storage limit for
|
||
|
the AUTL has been reached. This would happen even if there were unused entries
|
||
|
available for objects that reside in *SYSBAS. Likewise, if an attempt is made to
|
||
|
secure an object that resides in *SYSBAS with an AUTL but all of the AUTL's
|
||
|
*SYSBAS entries have been used; an MCH2804 exception will occur even if there are
|
||
|
unused entries available in authorization list extensions for the AUTL.
|
||
|
</p>
|
||
|
|
||
|
<p>To effectively manage the fullness of an AUTL, a user needs to ensure that
|
||
|
no single set of entries (the *SYSBAS set and the authorization list extension sets)
|
||
|
exceed their individual 2,097,104 entry limit.
|
||
|
</p>
|
||
|
|
||
|
<p>This API returns information about the total number of entries used for
|
||
|
*SYSBAS and all varied on independent
|
||
|
ASPs for the specified
|
||
|
AUTL as well as detailed entry use information for *SYSBAS and each varied on
|
||
|
independent ASP.
