ORA-07445 with ORA-03113: end-of-file on communication channel

Filed under: Oracle — by enotebook @ 5:21 pm

I was encountering an error when executing a SQL query on a development server, which is ORA-03113: end-of-file on communication channel. After the investigation i found it’s caused by an Oracle bug – bug No. 4517291. Here is the process to solve this problem.
