glacier2 and icepack for sessionmanager,permissionsverifier

seth.piezas

hi-

is it possible to run the sessionmanager and permissions verifier for Glacier2 with an IcePack IceBox?

right now i'm getting this error when setting Glacier2.PermissionsVerifier=name@adaptername in the config.

Reference.cpp:967: Ice::NoEndpointException:
no suitable endpoint available for proxy `PermissionsVerifier -t @ adaptername

is glacier2 able to use location indirection for this service?

thanks

Hi,

Yes, Glacier2 should be able to use an indirect proxy for the permissions verifier. Did you configure Glacier2 with the locator proxy?

Locator now working, new error

thanks. it did look indeed like the locator was the initial problem.

however, looks like glacier doesn't want to accept it as a sessionmanager object. but the object is a direct sublass of Glacier._SessionManagerDisp (JAVA).

glacier2router: error: session manager `ConnectionManager@myrtle.ConnectionService.Connection' is invalid

any ideas?

thanks,

mes

That message means that the checkedCast failed on the session manager proxy. I suggest running the router with the following properties enabled to see if it gives you any clues:

Ice.Trace.Network=3
Ice.Trace.Protocol=1
Ice.Trace.Retry=2

If you're still having trouble, attach the output from the router when running with these properties. Even better would be an archive containing an example that demonstrates the problem.

wow

that's some nice tracing.

i'm going to dig through for a while. i'll put an archive together if the error persists.

thanks again,

Perhaps it's just a typo... but in case it's not and if you're using Glacier2, your session manager servant should extend Glacier2._SessionManagerDisp, not Glacier._SessionManagerDisp.

not just a typo

thanks. i thought the sessions were compatible.

on another note, i was wondering how ice dealt with changing libraries for upgrading, etc. if i specifically stop a server through the admin console, can i switch out the underlying jar and restart the server with the new code? i understand part of this can be considered an implementation detail of the JVM, etc. but does ice do anything specifically to check and force reloading when a server changes its activation state from deactivated to activated?

thanks,

Hi Seth,

Ice does not perform any explicit checks for changes to its run time library.
