我试图限制提取频率，并在用户指南（https://www.symmetricds.org/doc/3.9/html/user-guide.html#_extract_frequency_by_channel）中找到了两种方法。他们都没有工作。
1）通过设置extract_period_millis。
update sym_channel set extract_period_millis = 30000, last_update_time=CURRENT_TIMESTAMP where channel_id='channel_bps2swd'
之后，我在控制台上收到以下错误消息：

[server] - NodeConcurrencyInterceptor - Error building response headers
我不得不退后extract_period_millis = 0来解决此错误消息。
注意：表SYM_NODE_CHANNEL_CTL为空
2）通过将表SYM_NODE_GROUP_CHANNEL_WND的开始/结束时间设置为关联频道。
它没有任何影响。更改发生后不久便进行了同步。
系统： 对称3.9.12，Windows 10 x64，mssql
有没有设置同步频率的解决方案？
答案 0 :(得分：1)
如果只是想更改同步频率，则可以使用以下参数，因为它们都默认为1分钟（60000毫秒）。
job.pull.period.time.ms
job.push.period.time.ms
答案 1 :(得分：0)
在课堂上 org.jumpmind.symmetric.service.impl.ConfigurationServiceSqlMap.java
添加此 putSql（“ selectNodeChannelControlLastExtractTimeSql”，“从sym_node_channel_ctl中选择channel_id，last_extract_time，其中node_id =？”）；
