ORA-04030: out of process memory ...(initSubHeap:qk...)的错误解决

现象:
执行
SELECT s.index_name, s.table_name, s.uniqueness, s.index_type, s.table_owner FROM all_indexes s WHERE owner = 'BJJH'  AND (funcidx_status IS NULL OR funcidx_status != 'DISABLED') AND table_name not in (SELECT object_name table_name FROM all_objects WHERE owner = 'BJJH'  AND object_type = 'TABLE' AND table_name in  (SELECT table_name from all_snapshots where owner = 'BJJH' )) AND index_name not in (select constraint_name from all_constraints where table_name=s.table_name AND owner= 'BJJH'  AND constraint_type iN ('P','U'))时出错,报
ORA-04030: out of process memory when trying to allocate 82464 bytes错误。

在数据后台日志中也出现:
Errors in file /u01/app/oracle/base/database/diag/rdbms/lisdbuat/lisdbuat/trace/lisdbuat_ora_15597602.trc  (incident=192444):
ORA-04030: out of process memory when trying to allocate 82464 bytes (initSubHeap:qk,travElemP:qkspmTravCreate)
Incident details in: /u01/app/oracle/base/database/diag/rdbms/lisdbuat/lisdbuat/incident/incdir_192444/lisdbuat_ora_15597602_i192444.trc
的错误信息。

解决:
查询Oracle Support, 确认是由于触发了BUG引起的。通过修改:
alter system set "_optimizer_reuse_cost_annotations" = FALSE;
alter system set "_push_join_predicate" = FALSE;
alter system set "_fix_control"='5302124:off';
alter system set "_optimizer_fast_pred_transitivity"   = false ;
几个隐含参数后,问题得以解决。
