If you are Active/Passive then apply SP3 to Node A and follow the prompts. &nbsp;You don't need to apply SP3 to Node B, it will happen automatically. &nbsp;(That's described on the web)

Does it need downtime to apply SP3 on SQL Server 2005 cluster environment? <br />
Is it need install SP3 on both nodes of SQL Server 2005 cluster environment?<br />
Do we need to restart SQL Server Agent or any SQL Server services after SP3 applied?<br />
Thanks!

Microsoft SQL Server 2005 is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning. It includes support for managing XML data and allows a database server to be exposed over web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests.
