Question: I am using FIBPlus 4.7x and Firebird 1.5 RC6. I am having a problem with data not being visible between workstations. One workstation will add a record and the others can't see it unless they close and reopen the program. Must I really close and re-open the dataset in order to see changes to my dataset?
Answer: Probably you are using Snapshot isolation, you need to change the transaction isolation to ReadCommited in the transaction component, but you also need to read some information about transaction handling with Firebird, search this web site for transaction documents. Surely refresh or CloseOpen will do it and the dataset will seem to remain open. Good idea to get a bookmark first. You can try FullRefresh.

Our 911 dispatch center needed a program to monitor the status of equipment used in emergency situations. If one dispatcher modified the status of a piece of equipment, all the other dispatchers needed to see this change immediately. The most elegant way to implement this was by using Firebird Events to asynchronously notify all the users whenever a pertinent change had occurred at the database server. After failing to implement this myself using the Firebird API, I bought a copy of FIBPlus. I dropped a Database, EventAlert and ErrorHandler control into a C++ Builder DataModule and within minutes I had all the functionality I needed. I was able to complete the project quickly and the users are thrilled with the results because I gave them more features than they originally asked for. >>
