### 更换 license
```
通用机服务器替换license步骤：
特别说明：①、如果是集群先停掉集群：su - kingbase(切换到kingbase用户) ，kingbase_monitor.sh stop（停掉集群）
②、如果是单机停掉单机：：su - kingbase(切换到kingbase用户) ，sys_ctl stop -D data完整路径 （停掉单机数据库）
ps -ef | grep kingbase可以看到数据库的安装路径，下面以/home/kingbase安装路径介绍
第一步，执行：find /home/kingbase -name license.dat ，看license.dat在哪些路径。（数据库如果是装在windows上的话直接找到替换，重启数据库即可，不用执行下面的步骤，windows只能用标准版授权）
第二步：把上一步找到的路径记录下来。
第三步：根据上一步的路径把原有license.dat重命名为license.dat_old或者其他名字也行
第四步：把我给的授权上传到服务器，改为license.dat，并且执行chown -R kingabse:kingbase license.dat（用什么用户安装的数据库用户权限给到哪个用户，这一步建议用root用户进行授权）
第五步，执行su - kingbase切换到kingbase用户，把最新的license拷贝到第二步记录下来的路径。
最后一步，启动数据库①、集群：kingbase_monitor.sh start (sys_monitor.sh start)
②、单机：sys_ctl start -D /home/kingbase/KingbaseES/V8/data
[root@captor-101 ~]# find / -name kingbase.conf
/dbdata/data/kingbase.conf
[kingbase@captor-101 V008R006C006B0013PS003]$ sys_ctl stop -D /dbdata/data

[kingbase@captor-101 V008R006C006B0013PS003]$
[root@captor-101 ~]# find /home/kingbase -name license.dat
/home/kingbase/KingbaseES/V8/license.dat
/home/kingbase/KingbaseES/V8/KESRealPro/V008R006C006B0013PS003/license.dat
[kingbase@captor-101 V008R006C006B0013PS003]$ chown -R kingbase:kingbase license.dat
[kingbase@captor-101 V008R006C006B0013PS003]$ sys_ctl start -D /dbdata/data
```
### 备份重启服务
```
1、确认应用是否已经停止
2、进行手工逻辑全量备份:
su - kingbase
sys_dumpall -Usystem > XXXX/db_fullbackup.sql (XXXX路径为kingbase用户属主的存储路径)
3、ksql test system 登录数据库，查询活动用户连接情况：
select usename,count(*) from sys_stat_activity where state !='idle' group by usename;
4、\q退出数据库登录，sys_monitor.sh stop停止数据库集群
5、确认数据库服务器正常启动的情况下：sys_monitor.sh start启动数据库集群
```
### 备份和数据恢复
```sql
-- rename 数据库
test=# ALTER DATABASE easyviews RENAME TO easyviews_bak;
ALTER DATABASE
-- rename 表
ALTER TABLE my_table RENAME TO new_table;
```
[sys_dump](https://help.kingbase.com.cn/v8.6.7.12/admin/reference/ref-client/app-pgdump.html#id7)
```sql
-- 要把一个数据库 mydb 转储到一个 SQL 脚本文件
sys_dump -U system easyviews > 0224.sql
-- 脚本载入
ksql -f 0224.sql -U SYSTEM easyviews
-- 要转储一个名为 mytab 的表
sys_dump -U system -t mytab easyviews > db.sql
-- 要转储一个数据库到一个自定义格式归档文件：
sys_dump -Fc easyviews -U system > db.dump
-- 要把一个归档文件重新载入到一个（新创建的）名为 newdb 的数据库：
sys_restore -U system -d newdb db.dump
-- 把一个归档文件重新装载到同一个数据库（该归档正是从这个数据库中转储得来）中，丢掉那个数据库中的当前内容：
sys_restore -d easyviews -U system --clean --create db.dump
```
[sys-dumpall](https://help.kingbase.com.cn/v8.6.7.12/admin/reference/ref-client/app-pg-dumpall.html#sys-dumpall)
```
#备份
sys_dumpall -U system > 20240223kb.sql
#恢复
ksql -f 20240223kb.sql -U system easyviews
```
如果你要清空人大金仓数据库中的所有数据，可以执行以下 SQL 语句：
```sql
DROP SCHEMA public CASCADE;
CREATE SCHEMA public;
```
这两条语句的作用如下：
`DROP SCHEMA public CASCADE;`：删除数据库中的 public 模式以及该模式下的所有表、视图和其他对象。CASCADE 选项指定了如果有依赖于该模式的其他对象，则也会被删除。
`CREATE SCHEMA public;`：重新创建一个空的 public 模式，可以用来存储新的数据表和其他对象。
执行以上两条语句后，你的数据库将被清空，并且只剩下一个空的 public 模式。请注意，在执行这些操作之前，务必备份好原始数据，以防止不可逆的数据丢失。
