Hello there,

several days I spend with trying to create the connection to
Firebird 1.0.0.338 from Sun Java System Application server. When I
try to get the connection from data source, I receive this error
message:

Connection could not be allocated because: Resource Exception.
unrecognized database parameter block Reason: unrecognized database
parameter block

when I remove the conf. parameter MinSize or set it to 0. I obtain
this error message:

Target exception message: Connection could not be allocated because:
Could not obtain connection during blocking timeout (5000 ms)

is there any way to find the reason of the timeout above ?

there is my configuration of datasource below:

<jdbc-connection-pool connection-validation-method="auto-commit"
datasource-classname="org.firebirdsql.pool.FBWrappingDataSource"
fail-all-connections="false" idle-timeout-in-seconds="300" is-
