Corruption Problem

[Len Boorman]

I have generally used a single FE used by several Users to connect to a BE and experienced little of no problem. Both FE and BE residing on a network location.Concurrent users generally been 12 at most. Probably more around the 6-8. This has been with a normal network but where I am working now they use thin clients (WYSE) connecting to Citrix.

As previously I always select record lock as Edited record on every form that has edit capability. I am very careful about this and it seems to have worked very well for me in the past.

However I now find that I am getting frequent corruption of the FE on an application that I am launching on this thin client/citrix network.

It is only the FE that corrupts and always repairs without a problem but I do not understand why it is happening.

I have begun creating separate FE for specific groups of users to try to establish who is creating the corruption.

I have a thought that maybe the Citrix server accepts clients on a sort of anonymous basis. The ldb file certainly does not display data the way I have previously seen it displayed. previously it showed a each connected PC with PCID and say Admin as the user rights. The ldb I am getting with Citrix seems to be 3 chars followed by !!!!!!!!!!! and then without any spaces another 3 chars. These leading chars seem to be special characters. Not got example to hand but can post an example if it helps.

I have a suspicion that the recording locking detail generally held I believe via the ldb is being compromised by these strange ldb entries.

A thought. If I create a User interface for every user will this help as the record lock on the BE will be assigned via the ldb to a specific interface that has only one user.

All comments, thoughts and ideas as to why this corruption is happening welcome

I'm shaky on Citrix thing, but I do believe you still need to make sure each user has their own FE; that is, nobody should be sharing FEs. When two or more users open the same FE, corruption is inevitable, regardless of how it is used.

Thanks For the comments

I have created an individual FE for each user and will see how that goes.

Previously I have not had a problem with multiple users using a single FE but I take your point that individual FE's will assist and help me tracking down at least who/where the problem is being created
