Purpose Undocumented but part of Health Monitoring and related to DBMS_WLM.

Important Note: For the first demo for each procedure below, all parameter values are random strings and do not reference any real object.

The second demo, if one is present, is copied from $ORACLE_HOME/rdbms/admin/prvtsqtk.plb and provides an insight into how Oracle uses this package's functionality. Oracle's code has been properly formatted so that the functionality can be understood in the context of Library demos.

      /

ROW_CHECK

Undocumented

There is no constraint type in Oracle that could possibly be validated as "QQ" which appears to confirm our suspicion that execute has been granted to DBA but that either the package does nothing or contains no exception handling. hm_sqltk_internal.row_check( table_name IN VARCHAR2, col_list IN VARCHAR2, con_type IN VARCHAR2, chk_desc IN VARCHAR2);

exec hm_sqltk_internal.row_check('ZZYZX', 'A,B,C,D,E', 'QQ', 'Z');


      PL/SQL procedure successfully completed.

      

      BEGIN

        hm_sqltk_internal.row_check('tab$','obj#','PRIMARY KEY', 'Primary Key obj#');

      END;

      /

TAB_DESC

Undocumented hm_sqltk_internal.tab_desc( table_name IN VARCHAR2, tab_query IN VARCHAR2);

exec hm_sqltk_internal.tab_desc('ZZYZX', 'SELECT COUNT(*) FROM ZZYZX');

      

      PL/SQL procedure successfully completed.

      

      BEGIN

        hm_sqltk_internal.tab_desc('tab$', 'SELECT ''Object ''||u.name||''.''||o.name||'' is referenced'' FROM obj$ o, user$ u, tab$ t WHERE t.rowid = chartorowid(:1) AND t.obj# = o.obj# AND o.owner# = u.user#');

TAB_INIT

Undocumented hm_sqltk_internal.tab_init(init_table_name IN VARCHAR2);

exec hm_sqltk_internal.tab_init('ZZYZX');
