使用wrap加密pl/sql代码

发表于 2012 年 4 月 3 日由惜分飞

1.测试脚本

[oracle@bas ~]$ more pkg_wrap_xff.sql 
create or replace package pkg_wrap_xff is
  procedure welcome_in(abc in varchar2);
END pkg_wrap_xff;
/
create or replace package body pkg_wrap_xff is
  procedure welcome_in(abc in varchar2) as
  begin
    dbms_output.put_line('welcome ' || abc);
  end;
END pkg_wrap_xff;
/

2.创建并测试包

SQL> @pkg_wrap_xff

Package created.


Package body created.

SQL> set serveroutput on
SQL> exec pkg_wrap_xff.welcome_in('xifenfei');
welcome xifenfei

PL/SQL procedure successfully completed.

3.查看包内容

SQL> SELECT TEXT FROM dba_source a WHERE a.name='PKG_WRAP_XFF';

TEXT
--------------------------------------------------------------
package pkg_wrap_xff is
  procedure welcome_in(abc in varchar2);
END pkg_wrap_xff;
package body pkg_wrap_xff is
  procedure welcome_in(abc in varchar2) as
  begin
    dbms_output.put_line('welcome ' || abc);
  end;
END pkg_wrap_xff;

9 rows selected.

4.使用wrap加密

[oracle@bas ~]$ wrap iname=pkg_wrap_xff.sql oname=pkg_wrap_xff.plb

-rw-r--r--  1 oracle oinstall 273 Apr  3 10:58 pkg_wrap_xff.sql

[oracle@bas ~]$ more pkg_wrap_xff.plb

原则上来说wrap加密是不可逆的过程，所以可以通过使用wrap加密，实现了屏蔽代码的作用，确保了自己的知识产权。其实oracle本身很多的系统包也是通过这种方法进行加密处理，以保护oracle的产权。

网关不通致使vip/lsnr资源异常

这里可以看出由于vip资源失败，致使lsnr资源也出现失败，紧接着又是启动vip，再启动lsnr。所以使得我们通过crs_stat -t观察资源情况时，看到这两个进程一直处于波动状态

分析ora.rac1.vip.log日志

[ora.rac1.vip]: clsrcexecut:env ORACLE_CONFIG_HOME=/u01/app/oracle/product/10.2.0/crs_1
[ora.rac1.vip]: clsrcexecut:cmd=/u01/app/oracle/product/10.2.0/crs_1/bin/racgeut -e 
_USR_ORA_DEBUG=0 54 /u01/app/oracle/product/10.2.0/crs_1/bin/racgvip check rac1
[ora.rac1.vip]: clsrcexecut: rc = 1, time = 6.430s
[ora.rac1.vip]: end for resource = ora.rac1.vip, action=check,status=1,time=6.450s
[ora.rac1.vip]: ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
[ora.rac1.vip]: clsrcstartorp: Error with malloc
[ora.rac1.vip]: ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
Interface eth0 checked failed (host=rac1)
Invalid parameters, or failed to bring up VIP (host=rac1)

通过这里发现:从eth0网卡ping192.168.1.1(网关)不通,导致VIP资源不能正常工作

核实问题原因/解决
我们人工从节点1上ping 网关(192.168.1.1),果真不通.继续检查发现,网关服务器上意外的开启了防火墙,对部分进来的包进行了过滤,恰好节点1在被禁止之列,使得节点1 ping 网关不成功,从而出现该了该错误.关闭防火墙或者重新设置规则后,rac工作正常,未出现vip和lsnr资源出现波动情况.
