Here is a Windows Powershell function I wrote to call a generic stored procedure that will rebuild all indexes in a database. \u00a0(I found the stored procedure here:\u00a0http:\/\/www.wisesoft.co.uk\/scripts\/t-sql_defrag_indexes_for_database.aspx<\/a>) This turns out to be extremely useful for rebuilding indexes on a SQL Server-based connected directory at the end of each run of a Microsoft Forefront Identity Manager (FIM) MA that has undergone a lot of changes.<\/p>\n
