Hi,

When I run the SQL, I got ” ORA-12804: parallel query server appears to have died with ORA-12801: error signaled in parallel query server ” error.

This error is related with Partitioned table and Parallel execution on Cluster Nodes.

To solve this problem, You can run the same SQL as follows.

set the following trace events, then run the same SQL as follows.

alter session set events '10384 trace name context forever , level 16384';

declare
v_dyn clob;
begin

begin
execute immediate 'drop table ' || 'ODI' || '.' || 'ODI_TABLE purge';
