版本信息
配置快照列出数据库中指定节点的配置信息。
SDB_SNAP_CONFIGS
字段信息详见数据库配置。
构造扩展参数，可参考 SdbSnapshotOption。
| 参数名 | 参数类型 | 描述 | 是否必填 |
|---|---|---|---|
| Mode | string | 指定返回配置的模式，默认为"run" 在 run 模式下，显示当前运行时配置信息；在 local 模式下，显示配置文件中配置信息 |
否 |
| Expand | boolean | 是否扩展显示用户未配置的配置项，默认为 true | 否 |
构造扩展参数进行快照查询
> var option = new SdbSnapshotOption().options( { "Mode": "local", "Expand": false } )
> db.snapshot( SDB_SNAP_CONFIGS, option )
输出结果如下：
{
"NodeName": "sdbserver1:11830",
"dbpath": "/opt/sequoiadb/database/data/11830/",
"svcname": "11830",
"role": "data",
"catalogaddr": "sdbserver1:11823,sdbserver2:11823,sdbserver3:11823",
"omaddr": "sdbserver1:11785",
"businessname": "myService1",
"clustername": "myCluster1"
}
...指定服务名和组名进行快照查询
> db.snapshot( SDB_SNAP_CONFIGS, { GroupName:'group1', SvcName:'11830' } )
输出结果如下：
