Got ORA-1013 while running PLSQL

A big trace file was generated in udump,

The following content was in the trace file:

*** 2019-06-05 16:15:01.725
*** SESSION ID:(1159.11779) 2019-06-05 16:15:01.725

This is expected behavior, if using Ctrl+C to terminate a running PL/SQL, a trace file is generated for debugging purposes.

This issue can be reproduced by the following steps:
1. Open a session and running:

declare
n number;
begin
loop
n := n + 1;
end loop;
end;
/

==>Then terminate this session with ctrl+c

2. Check udump and a trace is generated:

Solution

To avoid generating big trace file, please set MAX_DUMP_FILE_SIZE to a smaller value to get smaller trace files:

For example:
You can run the following command to set MAX_DUMP_FILE_SIZE to 1GB:

SQL> alter system set max_dump_file_size='1024M';
SQL> show parameter max_dump_file_size
