<p>The Set Job User Identity (QWTSJUID) API has two operations that can be used
|
|
to explicitly set the job user identity of the current job. The two operations
|
|
are set and clear. The set operation explicitly sets the job user identity to
|
|
the name of the current user profile of the thread in which the API is called.
|
|
The clear operation clears any job user identity that was previously set by the
|
|
QWTSJUID API or the QwtSetJuid() function, and the default job user identity
|
|
will then take effect.</p>
|
|
|
|
<p>The <strong>job user identity</strong> is the name of the user profile by
|
|
which this job is known to other jobs. The job user identity is used for
|
|
authorization checks when other jobs on the system attempt to operate against
|
|
this job. Examples of functions that operate against another job include the
|
|
Start Service Job (STRSRVJOB) command, the Retrieve Job Information (QUSRJOBI)
|
|
API, the Change Job (QWTCHGJB) API, all job control commands, and functions
|
|
that send signals from one job to another.</p>
|
|
|
|
<p>The job user identity is not used to make authorization checks from within
|
|
this job. Authorization to perform a function is always based on the current
|
|
user profile of the thread in which the function is called.</p>
|
|
|
|
<p>This API is intended to be used by either multithreaded servers or single
|
|
threaded servers that want to establish a job user identity that remains
|
|
constant, regardless of the user profile under which it processes individual
|
|
client requests.</p>
|
|
|
|
<p>When a job user identity has not been explicitly set by an API, a job
|
|
running single threaded will have a job user identity that is the same as the
|
|
current user profile that the job is running under at the time. When a job user
|
|
identity has not been explicitly set by an API, a job running multithreaded
|
|
will have a job user identity that is the name of the user profile that the job
|
|
was running under at the time it became multithreaded.</p>
|
|
|
|
<br>
|
|
|
|
|
|
<h3>Authorities and Locks</h3>
|
|
|
|
<p>If the job user identity is currently set, then either *USE authority to the
|
|
user profile associated with the job user identity or all object (*ALLOBJ)
|
|
special authority is required. If the job user identity is not already set,
|
|
then no authorization is required.</p>

<p>Thread safety considerations:</p>
|

|

<ul>
|
|
<li>The set function is threadsafe.</li>
|
|
|
|
<li>The clear function may be called in a job that allows multiple threads, but

|
only while it is running single threaded. The clear function will not be

|
allowed if any secondary threads are active.</li>
