A couple days ago, a colleage brought our SQL Server to it's knees using a the RMV_Installed_File_Inventory view. He just wanted to look at some file versions and paths, so wrote something rather innocent looking,
SELECT vc.Name
,vif.[File Name]
,vif.[File Version]
,vif.[Path]
FROM [RMV_Installed_File_Inventory] vif
JOIN vComputer vc
ON vc.Guid = vif._ResourceGuid
WHERE LOWER(vif.[File Name]) IN ('oracleadnettest.exe')
ORDEAA BY vc.Name
All he wanted to do was to see where a specific executable 'oracleadnettest.exe' was located and what its version was. Once he'd realised the Altiris Console report window had gotten sulky, he gave me a call.
I was rather surprised to find that the SQL Server was hitting 99% CPU and it didn't give any indication of finishing any time soon. As it was already late afternoon, I decided to let it be and look at it again the next day when things were better.
So, the next day I went in the SQL Server, and went into SQL Server management studio. I thought that before I'd try anything fancy, I'd just do a simple row count. As I couldn't believe what happened next, I took a screenshot....
On the face of it it doesn't seem so bad. The view returned got just under 5million rows. Notice however the execution time. I didn't take this screenshot a few minutes after executing the query. I took it the next day when it completed. This query took a whopping 1 day, 1 hour and 28 minutes to execute.
So... anyone else seeing this?
For posterity, here is the revsion I made to the original console report query to avoid this view,
SELECT
vc.Name,
Inv_Installed_File_Details.Path AS [ Name],
Inv_Windows_File.ProductVersion AS [Version]
FROM dbo.vComputer vc
JOIN Inv_Installed_File_Details ON vc.Guid = Inv_Installed_File_Details._ResourceGuid
JOIN Inv_Windows_File ON Inv_Installed_File_Details.FileResourceGuid = Inv_Windows_File._ResourceGuid
WHERE Inv_Installed_File_Details.Name = N'oracleadnettest.exe'
ORDER BY vc.Name
And below is the T-SQL for the RMV_Installed_File_Inventory view which seems to be misbehaving.....
