Environments:
MS 2003 Server;
Windows Server 2008 32-bit.
1. Install DataEase 7.x on Citrix Server (this effectively becomes multiple-workstations and should be treated as such);
2. Make sure ‘FILES=100’ is set in the’ \WINDOWS\SYSTEM\CONFIG.NT’ file on the Citrix sever;
3. Alter/add the following registry settings as though you were dealing with a workstation;
The following are all of type DWORD:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManWorkstation\Parameters
UseUnlockBehind=0
UseOpportunisticLocking=0
UseLockReadUnlock=0
NOTE: If you are going to use load balancing across several CITRIX servers then points 1 to 3 need to be repeated on each CITRIX box.
4. Put the database in a separate directory on the server;
5. Create a named share to this database directory;
6. Create a CITRIX / MS User Group for the application;
Give the group:
b. MODIFY, READ & EXECUTE, READ, WRITE rights in the ‘Share’ that holds the Database directory.
7. Create all users for the application and add them to the group created above;
8. On the Database Server, alter/add the following Registry settings:
They are all of type DWORD.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters
EnableOpLocks=0
OpLocksDisabled=1
UtilizeNTCaching=0
UseUnlockBehind=0
UseOpportunisticLocking=0
UseLockReadUnlock=0
Note: All servers need rebooting before the individual registry settings become active on that particular machine;
Tests to make sure that it is working correctly:
1. Login to a Citrix application session as more than one of the users in the group on separate machines;
2. Login to the Database.
b. Test record caching is not occurring (server registry settings).
c. Test a form/report that contains lots of relationships. (Files = 100).
3. Look in file RDRRxxxx.ssn of the application folder. This file should be storing the logged in users/machine names.
