标题：Patch_SCN for Linux 功能完善

Patch_SCN工具目前有For win和for linux版本,主要用于修改Oracle SCN(特别是在oracle数据库非常规恢复中实现一键修改SCN功能,实现快速open数据库.主要解决典型问题:
ORA-600 2662
ORA-600 kclchkblk_4
ORA-600 kcbzib_kcrsds_1
最近有点空对Patch_SCN软件的for linux版本进行了完善,主要完善功能:
1. 整个代码全部通过C代码实现
2. 完善了注册机制
3. 无需输入内存地址,程序一般情况下可以直接获取地址并修改
上传软件到linux环境并授权
确保执行用户有x权限

[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ls -ltr /tmp/Patch_SCN 
-rw-r--r-- 1 root root 13984 Oct 13  2025 /tmp/Patch_SCN
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# chmod +x /tmp/Patch_SCN 
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ls -ltr /tmp/Patch_SCN 
-rwxr-xr-x 1 root root 13984 Oct 13  2025 /tmp/Patch_SCN

使用软件之前需要进行注册
第一次使用要求输入注册码

[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN

========================================
           Software Registration        
========================================
 
Your Hardware ID: XXXXXXX
 
Please send your Hardware ID to XiFenFei to register.

Tel/WX: +86-17813235971 
 
Enter Registration Code: 6F2EEF38-693AEA80
Registration successful!
Usage:
  Automatic address mode: ./Patch_SCN <pid> <new_value>
  Manual address mode:    ./Patch_SCN <pid> <address> <new_value>
  Where:
    <pid> - Oracle process ID (must be entered manually)
    <address> - Memory address (entered in manual mode, hexadecimal)
    <new_value> - SCN value to modify (must be entered manually, supports decimal or hexadecimal)

授权成功之后,后续使用软件无需注册

[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN 
Usage:
  Automatic address mode: ./Patch_SCN <pid> <new_value>
  Manual address mode:    ./Patch_SCN <pid> <address> <new_value>
  Where:
    <pid> - Oracle process ID (must be entered manually)
    <address> - Memory address (entered in manual mode, hexadecimal)
    <new_value> - SCN value to modify (must be entered manually, supports decimal or hexadecimal)

Patch_SCN使用演示
软件支持自动发现内存地址和手工输入内存地址两种模式(当某些情况无法软件自动发现地址时,可以考虑人工输入地址方式进行)

###############自动识别内存地址方式修改#############################
--修改scn之前
SQL> SELECT CURRENT_SCN FROM V$DATABASE;
 
CURRENT_SCN
-----------
 5691132517
 
---进行scn修改
[oracle@iZbp11c0qyuuo1gr7j98upZ tmp]$ ./Patch_SCN 18884 5691232517
Successfully obtained address automatically: 0x6001ae70
Original Oracle SCN at Address 0x6001ae70: 0x15337ca8a
Are you sure you want to modify Oracle SCN? (yes/no): yes
New SCN at Address 0x6001ae70: 0x153395105
Oracle SCN successfully modified.
 
--修改scn之后
SQL> SELECT CURRENT_SCN FROM V$DATABASE;
 
CURRENT_SCN
-----------
 5691232520   --->由于scn会自动增加,所以比修改值稍大一点
 
 
###############手工输入内存地址方式修改########################
---当程序提示无法获取到内存地址时,采用人工输入内存地址方式进行修改
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN 18884 5691232517
Could not find valid  SCN ddress
Failed to get SCN address automatically
Please use manual address mode instead
 
---使用get_addr程序获取内存地址,如果无法获取联系:xifenfei
[oracle@iZbp11c0qyuuo1gr7j98upZ tmp]$ ./get_addr
Retrieving Oracle SCN address...
Successfully retrieved SCN address: 0x6001ae70
 
---修改scn值
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN 18884 0x6001ae70 6691232517
Using manually provided address: 0x6001ae70
Original Oracle SCN at Address 0x6001ae70: 0x15339517f
Are you sure you want to modify Oracle SCN? (yes/no): yes
New SCN at Address 0x6001ae70: 0x18ed41b05
Oracle SCN successfully modified.
 
---验证修改之后scn值
SQL> SELECT CURRENT_SCN FROM V$DATABASE;
 
CURRENT_SCN
-----------
 6691232521  --->由于scn会自动增加,所以比修改值稍大一点
