Solution
Check the memory componenet in Oracle.
SQL> show parameter sga
NAME TYPE VALUE ----------- --------- --------- lock_sga boolean FALSE pre_page_sga boolean FALSE sga_max_size big integer 6528M sga_target big integer 6528M
SQL> show parameter pga
NAME TYPE VALUE -------------------- ----------- --------- pga_aggregate_target big integer 0
-- IF pga aggregate is zero then check memory parameter
SQL> show parameter memory
NAME TYPE VALUE ------------------------- ----------- ------- hi_shared_memory_address integer 0 memory_max_target big integer 0 memory_target big integer 0 shared_memory_address integer 0
2. Set the value of PGA target because memory target or PGA target is not set.
alter system set pga_aggregate_target = 2G scope=spfile;
3. It’s fixed the issue in EXPDP.
