i am having a bit of a linked server problem .

I created a sql server linked server and it's been working fine for last 2 years and suddenly not working .

SQL Server Microsoft SQL Server 2005 - 9.00.5324.00 (X64) Aug 24 2012 18:28:47 Copyright (c) 1988-2005 Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 2)

Oracle client version Oracle - OraClient11g_home1

Cannot create an instance of OLE DB provider "OraOLEDB.Oracle" for linked server

Ps : we have enabled Allow in Process in Sql Server for Oracle Provider

anyone got any ideas on this and what can be done to avoid this happen again

You need to figure out what changed in the environment around that time (Windows Updates? Service pack application?). Things don't usually blow up by themselves without some kind of provocation. –  Jon Seigel Aug 6 '13 at 16:58
