windows server 2008 - MS Access Database slower than normal all of a sudden




I have a client with an Access Database that has been experiencing slow queries in the past few days. Here is some background first.




  • it is currently running on Windows Server 2008

  • the mdb file is on the server and there are some local installed front end parts on the
    workstations.

  • we run over a gigabit ethernet and gigabit network switches

  • this server is used for basic file sharing too and those other services DO NOT seem to run slow or exhibit any issues.

  • this was working fine but has begun having slower queries or response times when you connect back to the database for queries.

  • we have not changed anything on the server or done any updates to either the server or the database front end installation.


  • we have always used a mapped drive letter to access it, both on the old server and on this new one, see next point for age of new server.

  • I know people will say stop using Access as a database but the client is using legacy software with NO path to upgrade and it was working, in a tolerable fashion, on this Server 2008 platform for about 1.5 years already.



My question is basically is there anything that I should be looking at that is maybe obvious but I might be missing? We tried moving the files to another partition on a faster raid array and we got the same results.



Any help would be greatly appreciated.

I second Zoredache's question about compacting the mdb file. When our apps were all Access based, i used to use Microsoft's Jet Database command line tool. It works great and keeps you from having to open and close the mdb in Access which could take a bit if it is already having issues. Check it out here. http://support.microsoft.com/kb/295334




A few other things:
How busy is the server itself? (age of it means nothing if it is getting slammed by some other process
Are all the copies of Access running on the same version? It's possible there is some glitch on one of the workstations creating locks for the other users
Is the database corrupt? (the jet tool can help with that)

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits,

apache 2.2 - Server Potentially Compromised -- c99madshell

So, low and behold, a legacy site we've been hosting for a client had a version of FCKEditor that allowed someone to upload the dreaded c99madshell exploit onto our web host. I'm not a big security buff -- frankly I'm just a dev currently responsible for S/A duties due to a loss of personnel. Accordingly, I'd love any help you server-faulters could provide in assessing the damage from the exploit. To give you a bit of information: The file was uploaded into a directory within the webroot, "/_img/fck_uploads/File/". The Apache user and group are restricted such that they can't log in and don't have permissions outside of the directory from which we serve sites. All the files had 770 permissions (user rwx, group rwx, other none) -- something I wanted to fix but was told to hold off on as it wasn't "high priority" (hopefully this changes that). So it seems the hackers could've easily executed the script. Now I wasn't able
