DQS, by default, uses connection timeout of 1 minutes when connecting to external Reference Data Services (RDS) provider. You can modify the timeout setting, using the following steps:
- Run the following query on SQL Server where DQS is installed:
SELECT [ID]
,[SERVICE]
,[NAME]
,[UPDATE_TIME]
,[DESCRIPTION]
,[VALUE]
,[REVISION]
FROM [DQS_MAIN].[dbo].[A_CONFIGURATION]
where id=916
- Click on the value cell (XML) and copy the XML output
- Change the ConnectionTimeout parameter (default 60000 or 1 minute) and update the record ( Tips : Make sure to update DQS_MAIN database before you make the update), for example:
BEFORE
update [DQS_MAIN].[dbo].[A_CONFIGURATION]
set value = '<configuration name="ReferenceData">
<param name="CacheEnabled" value="1" />
<param name="CacheCleanupIntervalMinutes" value="1440" />
<param name="CacheInvalidationTimeHours" value="24" />
<param name="CacheSizeEntries" value="1000000" />
<param name="BatchQuerySizeEntries" value="100" />
<param name="QueryMinConfidence" value="0.4" />
<param name="QueryMaxSuggestions" value="5" />
<param name="ProxyAddress" value="" />
<param name="ConnectionTimeout" value="60000" />
<param name="DataMarketCatalogEntryPoint" value="services/my/Datasets?$filter=Category%20eq%20''Data Quality Services''" />
<param name="MetadataEntryPoint" value="/$metadata" />
<param name="RetryErrorCodes" value="504" />
<param name="RetryReduceFactor" value="5" />
</configuration>'
where id=916
AFTER
update [DQS_MAIN].[dbo].[A_CONFIGURATION]
set value = '<configuration name="ReferenceData">
<param name="CacheEnabled" value="1" />
<param name="CacheCleanupIntervalMinutes" value="1440" />
<param name="CacheInvalidationTimeHours" value="24" />
<param name="CacheSizeEntries" value="1000000" />
<param name="BatchQuerySizeEntries" value="100" />
<param name="QueryMinConfidence" value="0.4" />
<param name="QueryMaxSuggestions" value="5" />
<param name="ProxyAddress" value="" />
<param name="ConnectionTimeout" value="300000" />
<param name="DataMarketCatalogEntryPoint" value="services/my/Datasets?$filter=Category%20eq%20''Data Quality Services''" />
<param name="MetadataEntryPoint" value="/$metadata" />
<param name="RetryErrorCodes" value="504" />
<param name="RetryReduceFactor" value="5" />
</configuration>'
where id=916
