Hi, I have a problem with Mapi which did not seem to occur in previous releases of MonetDB (<4.15). In the past, I could start an Mserver with a mil script that declared some PROCs, and then let this Mserver accept Mapi connections, with the Mapi clients being able to call the functions that were declared in the server-side startup script. However, since the latest release, the server-side PROCs seem to be invisible to the client: MAPI = monetdb@kanda:50012 QUERY = template_conj_2(1, bat(void, lng).seqbase(0@0).append(lng (5394205300074141533)).append(lng(3189196963433190955))); ERROR = !ERROR: interpret: no matching MIL operator to 'template_conj_2(int, BAT[oid,lng])'. If I execute exactly the same call in the server-side console, it just works... Any ideas on this? And whether there is an easy fix? Cheers Sandor
