# 弱读查询失败，报 cluster weak read service is disabled

更新时间：2026-05-26 09:46

适用版本： V2.2.x、V3.1.x、V3.2.x 内容类型：Troubleshoot  

## 问题现象

尝试执行弱读查询，但失败，报错如下。

```shell
 obclient [SYS]> Select /*+ READ_CONSISTENCY(WEAK)*/ count(*) records,
 sum(to_number(substr(dbms_crypto.hash(utl_raw.cast_to_raw('Hash'
 ||"SUBSID"
 ||"ORDERLINEID"
 ||"REGION"
 ||"OLDPRODID"
 ||"NEWPRODID"
 ||"STARTTIME"
 ||"RECDATE"
 ||"STATUS"
 ||"STATUSDATE"
 ||"ORDERID"
 ||"NOTES"
 ),2),24,8),'xxxxxxxx')) HASH_VAL
 From NGCRM_XX.CS_REC_PRODCONVERT_WAITING;
 ORA-00600: internal error code, arguments: -4007, cluster weak read service is disabled, weak read not supported

```

## 问题原因

排查弱读相关参数：

- `max_stale_time_for_weak_consistency`: [用于设置弱一致性读允许读到多旧的数据](https://www.oceanbase.com/docs/enterprise-oceanbase-database-cn-10000000000356306)。
 - `weak_read_version_refresh_interval`: [设置弱一致性读版本号的刷新周期](https://www.oceanbase.com/docs/enterprise-oceanbase-database-cn-10000000000356286)。

#### 注意

当 `weak_read_version_refresh_interval` 值为 0 时，OceanBase 数据库不再刷新弱一致性读版本号，不论当前弱读版本号是否满足 `max_stale_time_for_weak_consistency`，均无法提供弱读服务。

## 适用版本

OceanBase 数据库 V2.x，V3.x 版本。

## 解决方法

将参数 `weak_read_version_refresh_interval` 恢复为默认值即可。

```shell
obclient > ALTER SYSTEM SET weak_read_version_refresh_interval = 50ms;

```
