SYMPTOM(s):

Error 748 when launching application from OpenEdge Architect

The server or the system has no more resources. Please contact Progress Technical Support. (748)

Error is received if application is launched while DB Navigator is connected to the same database to which the application connects.

FACT(s) (Environment):

Error is not received if DB Navigator is not connected at the time the application is launched.
Architect project auto starts and auto stops the database.
Default values are used for database startup.
Project uses shared AVM.
Several other projects are open.
Machine has only an Architect license; no separate database license.
Windows
OpenEdge 10.2B

CAUSE:

OpenEdge Architect has exceeded the maximum number of connections allowed for the database. Architect can use multiple database connections in one or more of the following ways:

Each open project that connects to a given database and does not use a shared AVM uses one ABL connection.
Any open projects that use a shared AVM which connects to a given database use one ABL connection which is shared among them.
Run configurations by default launch their own AVM's that have their own database connections.
If DB Navigator has an active connection to the database, that connection is a SQL connection. If a broker serves both ABL and SQL clients, once a server has been started for a SQL client any remaining connections allowed for that server can only be used for SQL connections; they are unavailable for ABL connections.

FIX:

To gain additional connections for use by OpenEdge Architect, consider one or more of the following:

Close projects that are open unnecessarily.
Close DB Navigator connections that are not needed.
Increase values for the database startup parameters -n (Number of Users), -Mn (Maximum Servers), -Ma (Maximum Clients per Server), and/or -Mpb (Maximum Servers per Broker), up to the maximum number of connections allowed by the product license.
