Manual failover of cluster-MSDTC

  • I tried to manually failover the sql service to another node. I was successfull in doing so, but MSDTC remains on the passive node. Let us assume in network guys are applying patches on the passive node. They just moved the sql services to the other node and msdtc remains on the passive node. Does it creates any problems?

  • Also can somebody explain me this sentence--

    •If you have linked servers running distributed transactions, then MS DTC is required.

    We have linked servers established from cluster server to other non clustered servers. So we need to have MSDTC?

  • DTC is only required when the linked servers is using distrbuted transactions. Other functionality like replication might also need DTC.
