Hi,

Can anyone tell me that why do we need to re-login after doing Convert to Runtime Data Dictionary? The changes we make in table def or in domain are not directly saved in Runtime Directory? ASAP

Yes the changes are done, but the RTDD is read at the login time only... It cannot be other way, imagine if a user is logged when you change the RTDD, by example adding a field in the table he is using...

There are several reasons, why Baan implemented it like this:

a) Performance: The runtime information is read once at login and then cached in memeory by the bshell. This way, a lot opf IO is avoided.

b) Consistency: During a RDD the DD on disk is until completion ina partial inconsistent state. For example a domain might be added, but the defintiion of the table not changed yet etc.

c) Survival (lacking a good description for this): If the changes would take effect imemdiately, then this might even kill the bshell of the Administrator executing the RDD himself, for example when patching in tools.

d) Quick undue: If something goes wrong, the Admin might at least be partial able to revert quickly the changes by simply restoring an old DD. I know, many this will result in several problems, but a 50% running system might be better then none at all.

There might be more good reasons ...

Regards

Markus

I never thought about this but in my opinion the runtime information is read once at first use not at login.
