dbms_output size buffer overflow

问题

I tried to set the dbms_output size to unlimited inside a stored procedure.

But it gave me compilation errors. So I tried in the SQL*Plus prompt the below way. But still I get the buffer overflow error. How can I overcome this?

 set serveroutput on size unlimited;
 exec service_update;


ORA-20000: ORU-10027: buffer overflow, limit of 30000 bytes
ORA-06512: at "SYS.DBMS_OUTPUT", line 32
ORA-06512: at "SYS.DBMS_OUTPUT", line 97
ORA-06512: at "SYS.DBMS_OUTPUT", line 112
ORA-06512: at "ARBOR.SERVICE_UPDATE", line 27
ORA-06512: at line 1

回答1:

In the procedure service_update, by any chance is there a call to

dbms_output.enable(30000); 

This may override the first limit you set.

回答2:

In Oracle 10gR2 you may also use unlimited buffer (https://forums.oracle.com/forums/thread.jspa?threadID=361639):

dbms_output.enable(null);
