the system security function.</p>

REVOKE statements or the CL commands Edit Object Authority (EDTOBJAUT), Grant

Object Authority (GRTOBJAUT), and Revoke Object Authority (RVKOBJAUT). </p>

<div class="section"><p>The SQL GRANT and REVOKE statements operate on SQL functions,

SQL packages, SQL procedures, distinct types, sequences, tables,
|
||
|
|
views, and the individual columns of tables and views. Furthermore, SQL GRANT
|
||
|
|
and REVOKE statements only grant private and public authorities. In some cases,
|
||
|
|
it is necessary to use EDTOBJAUT, GRTOBJAUT, and RVKOBJAUT to authorize users
|
||
|
|
to other objects, such as commands and programs.</p>

application server. *USER is the default for system (*SYS) naming.</li>
|

<li>If the USRPRF value is *OWNER, the authority to run the SQL statement
|

|
locally is checked using the user profiles of the user running the program
|

and of the owner of the program. The authority to run the SQL statement remotely
|

|
|
is checked using the user profiles of the application server job and the owner
|

of the SQL package. The higher authority is the authority that is used. *OWNER

server job and the owner of the SQL package. The highest authority is the

authority that is used. Because of security concerns, you should use the *OWNER
|

parameter value for DYNUSRPRF carefully. This option gives the access authority

of the owner program or package to those who run the program.</li>
