Hello,
We have a new DMA (on 10.5 CU5) installed using the 10.4 installer with clustered database - one external Linux node running both Cassandra(4.1.9) and OpenSearch(2.11.1).
While the DMA is working correctly with proper connection to database, there is this error in SLDBConnection log file :
2025/08/06 01:13:21.675|SLDataGateway|GetActiveRootAlarms|ERR|0|1|DBGatewayException(SLCassandraClassLibrary.DBGateway.Cassandra.StorageManagers.SingleNode.CassandraConnection,,READ_DATA) (Code: 0x80040319) SLDataGateway.Types.Exceptions.UnsupportedQueryException: Active alarms query does not support DMA & Element ID != 2100000000 on Cassandra.

at SLCassandraClassLibrary.DBGateway.DBGateway.GetActiveRootAlarms(Int32 dmaID, Int32 eID, Int32 amount, Object& result)
I have checked SLSearch and other log files - as mentioned previously, everything is working correctly.
What does this error mean and is there a way to fix it ?
Hi,
This 'error' can be safely ignored.
During startup DataMiner will read out all relevant active alarms from database and it does so by trying to read them all at once first. If thats not supported (UnsupportedQueryException) it reads them out per element.
As this is not really an error to worry about, we changed it to no longer log it as of DataMiner 10.5.6/10.6.
