Question

Below are the statements that I run to remove and recreate a USER and TABLESPACE on my local machine in oracle.

DROP TABLESPACE X INCLUDING CONTENTS AND DATAFILES ;
DROP USER X CASCADE;
CREATE TABLESPACE X DATAFILE '$ORACLE_PATH/X.dbf' SIZE 128M AUTOEXTEND ON EXTENT MANAGEMENT LOCAL AUTOALLOCATE SEGMENT SPACE MANAGEMENT AUTO;
CREATE USER X IDENTIFIED BY xxxxxxx DEFAULT TABLESPACE X TEMPORARY TABLESPACE temp;
GRANT exp_full_database TO X;
GRANT CONNECT,RESOURCE,DBA TO X;

We recently added a condition to disable the lock on a table in this TABLESPACE and the above DROP command now issues:

Error report:
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-00069: cannot acquire lock -- table locks disabled for TABLE
00604. 00000 -  "error occurred at recursive SQL level %s"

Does anyone know of a way to DROP the USER and TABLESPACE without enabling the LOCKs or a better method to recreate a local TABLESPACE and USER with locks disabled?

Cheers

The purpose of the DISABLE TABLE LOCK command is to prevent DDL. If you could drop the table without re-enabling the table lock first that would be a bug to me.

In your case you will have to enable table locks with a script such as this one:

BEGIN
   FOR cc IN (SELECT owner, table_name
                FROM all_tables
               WHERE tablespace_name = :x
                 AND table_lock = 'DISABLED') LOOP
      EXECUTE IMMEDIATE 'ALTER TABLE "' || cc.owner || '"."' || 
                         cc.table_name || '" ENABLE TABLE LOCK';
   END LOOP;
END;

Unfortunately it may take a very long time to execute or even fail unexpectedly:

Caution: Oracle Database waits until
active DML transactions in the
database have completed before locking
the table. Sometimes the resulting
delay is considerable.
