tomcat 应用Message file 'oracle.net.mesg.Message' is missing问题处理

1，问题描述

2，查看数据库能否正常操作

SQL> create table zz_bak (id  number);
Table created
SQL> insert into zz_bak(id) values(1);
1 row inserted
SQL> commit;
Commit complete
SQL> select * from zz_bak;
ID
----------
1
SQL> drop table zz_bak;
Table dropped

SQL>

3，查看是否有数据库锁

-- 用dba权限的用户查看数据库都有哪些锁，没有查询到记录
selectt2.username,t2.sid,t2.serial#,t2.logon_time from v$locked_object t1,v$sessiont2 where t1.session_id=t2.sid order by t2.logon_time;

-- 查看session等待，也没用记录
SELECT/*+ rule */ lpad(' ', decode(l.xidusn, 0, 3, 0)) || l.oracle_usernameUser_name,o.owner,o.object_name,o.object_type,s.sid,s.serial#,p.spid
FROMv$locked_object l, dba_objects o, v$session s, v$process p
WHEREl.object_id = o.object_id
AND l.session_id = s.sid and s.paddr =p.addr
ORDERBY o.object_id, xidusn DESC

4，检查应用程序所在的linux服务器
