[Mono-list] Connecting to Oracle database from service at boot

I have a windows service running using mono-service on openSUSE 11.1. The
service attempts to start using the init script I have configured ok but
then generates the following error during the first attempt to access an
Oracle XE (10g) database. 

Could not allocate the Oracle environment.   at
System.Data.OracleClient.Oci.OciGlue.CreateConnection (OracleConnectionInfo
conInfo) [0x00000]

  at MonoTestService.MonoTest.OnStart (System.String[] args) [0x00000] 

If I login as root and stop the service and restart it then it runs without
problems and the database is accessed successfully. I cant understand why it
runs successfully when I start it manually but won't do so at boot. Can
anyone help?
