二、简述

工作和兴趣相结合的产物，既能更好的完成工作，也能看看自己的学习情况如何，无论如何，大家一起加油。

三、升级点

序号功能备注
1避免对于视图的操作视图不需要做清理空洞率操作。
2清理空洞率步骤函数的优化避免某些特殊场景下的异常，例如SQL或执行者进程被强杀。
3对于消息队列中的任务进行限制避免执行者进程执行任务过慢，导致消息队列中的任务积压，致使达到消息队列最大字节数限制。

四、支持功能

序号功能备注
1多进程执行任务 
2空洞率清理 
3自定义配置后续会细讲参数。
4SQL重试功能如果sql执行出错，会尝试3次。

五、空洞率

大家可以参考之前的博客《南大通用数据库-Gbase-8a-学习-33-空洞率查询与解决方法》。

六、工具流程图

0edc423c21334640a92b67a853b896a2.png

1、管理者进程检查传入参数是否正确。

2、管理者进程启动会去Gbase8a中检索需要清理空洞率的表。

3、管理者进程获取环境变量和创建消息队列。

4、管理者进程创建多个执行者进程。

5、管理者进程向消息队列发送消息，当消息队列中的任务到达100件时，获取消息队列状态，管理者进程休眠5s，继续获取消息队列中的任务数。

6、执行者进程检查传入参数是否正确。

7、执行者连接数据库和获取环境变量、连接消息队列。

8、执行者从消息队列中接收消息。

9、执行者进程操作数据库清理空洞率。

10、管理者进程发送完所有清理的表，向消息队列发送完成任务消息。

11、执行者进程接收到完成任务消息，清理申请的资源。

12、管理者进程回收所有执行者进程的PCB资源。

13、管理者进程关闭消息队列。

14、管理者进程清理申请的资源。

七、安装包下载地址

已经放到开头啦，欢迎大家测试使用。电脑端才可以看见安装包。

八、参数介绍

1、命令模板

[gbase@czg2 Exec]$ ./Manager 'DbHost;DbUser;DbPwd;DbName;DbPort;DbCharset;ChdProcessNum;TargetDb;VoidRate;CleanTabNum;'

2、命令样例

[gbase@czg2 Exec]$ ./Manager '192.168.142.12;czg;qwer1234;gbase;5258;utf8;3;zxj;0;2;'

3、参数表格

序号参数备注
1DbHost连接源端数据库IP。
2DbUser连接源端数据库用户。
3DbPwd连接源端数据库用户密码。
4DbName连接源端数据库。
5DbPort连接源端数据库端口号。
6DbCharset连接源端数据库的字符集。
7ChdProcessNum启动的子进程数。
8TargetDb需要清理空洞率的数据库。
9VoidRate空洞率到达此值时进行清理，1-100。
10CleanTabNum清理TargetDb下空洞率超过VoidRate的表的个数。如果是0，表示无限制。

九、安装步骤

大家可以看README的内容，其实是一样的。

下面的配置大家根据实际情况来，我这边只是给一个例子。

1、配置环境变量

/home/gbase/.bashrc中添加如下

export CLEAN_VOID_RATE_TOOL_HOME=/home/gbase/EasyClean/
export LD_LIBRARY_PATH=$CLEAN_VOID_RATE_TOOL_HOME/Libs:$LD_LIBRARY_PATH

2、生效环境变量

source /home/gbase/.bashrc

3、检验动态链接是否正常

[gbase@czg0 Exec]$ ldd Manager linux-vdso.so.1 =>  (0x00007ffe315b5000)libPublicFunction.so => /home/gbase/EasyClean//Libs/libPublicFunction.so (0x00007f54c1a1b000)libLog.so => /home/gbase/EasyClean//Libs/libLog.so (0x00007f54c1817000)libGbase8aOperate.so => /home/gbase/EasyClean//Libs/libGbase8aOperate.so (0x00007f54c160a000)libgbase.so.16 => /home/gbase/EasyClean//Libs/libgbase.so.16 (0x00007f54c114a000)libSqQueue.so => /home/gbase/EasyClean//Libs/libSqQueue.so (0x00007f54c0f45000)libDataConvertion.so => /home/gbase/EasyClean//Libs/libDataConvertion.so (0x00007f54c0d42000)libProcess.so => /home/gbase/EasyClean//Libs/libProcess.so (0x00007f54c0b3e000)libFileOperate.so => /home/gbase/EasyClean//Libs/libFileOperate.so (0x00007f54c0938000)libMyHashTable.so => /home/gbase/EasyClean//Libs/libMyHashTable.so (0x00007f54c0734000)libc.so.6 => /lib64/libc.so.6 (0x00007f54c0366000)libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f54c014a000)libdl.so.2 => /lib64/libdl.so.2 (0x00007f54bff46000)libm.so.6 => /lib64/libm.so.6 (0x00007f54bfc44000)/lib64/ld-linux-x86-64.so.2 (0x00007f54c1c1e000)[gbase@czg0 Exec]$ ldd Executor linux-vdso.so.1 =>  (0x00007ffddffde000)libPublicFunction.so => /home/gbase/EasyClean//Libs/libPublicFunction.so (0x00007f7563dff000)libLog.so => /home/gbase/EasyClean//Libs/libLog.so (0x00007f7563bfb000)libGbase8aOperate.so => /home/gbase/EasyClean//Libs/libGbase8aOperate.so (0x00007f75639ee000)libgbase.so.16 => /home/gbase/EasyClean//Libs/libgbase.so.16 (0x00007f756352e000)libSqQueue.so => /home/gbase/EasyClean//Libs/libSqQueue.so (0x00007f7563329000)libDataConvertion.so => /home/gbase/EasyClean//Libs/libDataConvertion.so (0x00007f7563126000)libProcess.so => /home/gbase/EasyClean//Libs/libProcess.so (0x00007f7562f22000)libFileOperate.so => /home/gbase/EasyClean//Libs/libFileOperate.so (0x00007f7562d1c000)libMyHashTable.so => /home/gbase/EasyClean//Libs/libMyHashTable.so (0x00007f7562b18000)libc.so.6 => /lib64/libc.so.6 (0x00007f756274a000)libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f756252e000)libdl.so.2 => /lib64/libdl.so.2 (0x00007f756232a000)libm.so.6 => /lib64/libm.so.6 (0x00007f7562028000)/lib64/ld-linux-x86-64.so.2 (0x00007f7564002000)

如果有动态库没有找到，就要看看环境变量是否配置正确或是否生效。
