使用pl/sql developer开发工具无法编译存储过程，触发器,包等程序文件

OS:RHAS 4
EBS:11.5.10.2

问题:使用pl/sql developer开发工具无法编译存储过程，触发器,包等程序文件,
出现not connect to oracle
检查oracle，alter.log文件，并出现如下错误:
Errors in file /ntkerp/orantkcn/erpdb/9.2.0/admin/erp_erp/udump/erp_ora_20918.trc:
ORA-07445: exception encountered: core dump [ptmak()+106] [SIGSEGV] [Address not mapped to object] [0x8] [] []

检查相关trc文件，发现提示:
*** 2007-06-05 16:56:44.341
ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [ptmak()+106] [SIGSEGV] [Address not mapped to object] [0x8] [] []
Current SQL statement for this session:
BEGIN
/* NOP UNLESS A TABLE OBJECT */
IF dictionary_obj_type = 'TABLE' AND sys.dbms_cdc_publish.active > 0
THEN
sys.dbms_cdc_publish.change_table_trigger(dictionary_obj_owner,dictionary_obj_name,'LOCK');
END IF;
END;

处理方法:
经过查找metalink,SQL> @?/rdbms/admin/rmcdc.sql
执行该sql文件，再用pl/sql developer编译通过

在$ORACLE_HOME/rdbms/admin下,这个sql文件也很简单！

DROP TRIGGER sys.cdc_alter_ctable_before;
DROP TRIGGER sys.cdc_create_ctable_after;
DROP TRIGGER sys.cdc_create_ctable_before ;
DROP TRIGGER sys.cdc_drop_ctable_before;
CALL sys.dbms_java.dropjava('-s rdbms/jlib/CDC.jar');
