Symptoms
When trying to drop a user, the command fails with errors ORA-00604 and ORA-00942

1. Example
SQL> drop user test ;
drop user test
*
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-00942: table or view does not exist

 

2. sql trace

alter session set sql_trace=true;

alter session set events'10046 trace name context forever,level 4';

 

SQL> drop user test ;

 

 

SQL trace (10046) trace will show a dml operation performed on system.aq$_internet_agent_privs
table.

----------------------------------------------------------------------------------------------------------
PARSE ERROR #5:len=78 dep=1 uid=0 ct=7 lid=0 tim=1416609304389 err=942
delete from system.aq$_internet_agent_privs WHERE db_username = NLS_UPPER(:1)
EXEC #1:c=70000,e=552054,p=148,cr=448,cu=0,mis=0,r=0,dep=0,og=4,tim=

STAT #2 id=1 cnt=0 pid=0 pos=1 bj=3490 p='TABLE ACCESS FULL OBJ#(3490) '
----------------------------------------------------------------------------------------------------------

 

3.Cause
The table system.aq$_internet_agent_privs is missing.

 

4.Solution
To implement the solution, execute the following steps:

a) Check if system.aq$_internet_agent_privs exist.

SQL> conn / as sysdba
SQL> desc system.aq$_internet_agent_privs

b) Make sure that the default tablespace of SYSTEM user is properly set to SYSTEM tablespace.

SQL> select default_tablespace from dba_users where username='SYSTEM';

DEFAULT_TABLESPACE
------------------------------
SYSTEM

c)If system.aq$_internet_agent_privs does not exist, run $ORACLE_HOME/rdbms/admin/catqueue.sql
script. manually logged in as 'SYS AS SYSDBA'. This will create the system.aq$_internet_agent_privs
table

SQL> conn / as sysdba
SQL> @$ORACLE_HOME/rdbms/admin/catqueue.sql
SQL> exit

d)Confirm that system.aq$_internet_agent_privs is created properly:

SQL> desc system.aq$_internet_agent_privs

Name Null? Type
----------- -------- ------------
AGENT_NAME NOT NULL VARCHAR2(30)
DB_USERNAME NOT NULL VARCHAR2(30)

 

5.Then execute the DROP USER command again.
