Key: CORE-5411 URL: http://tracker.firebirdsql.org/browse/CORE-5411 Project: Firebird Core Issue Type: Bug Components: API / Client Library Reporter: dominique.barrieu Hi, Since windows 10 a new problem come concerning connection to database. See bellow some log extracted from software : ----- 3156: Connection à la base sysdba masterkey read_only C:\AWRoot\bin\common\..\..\dtrd\database\FLOWCHART_CONTEXT.FDB 3156: Déconnection à la base C:\AWRoot\bin\common\..\..\dtrd\database\FLOWCHART_CONTEXT.FDB 3156: Connection à la base sysdba masterkey read_only C:\AWRoot\bin\common\..\..\dtrd\database\FLOWCHART_CONTEXT.FDB 3156: Déconnection à la base C:\AWRoot\bin\common\..\..\dtrd\database\FLOWCHART_CONTEXT.FDB 3156: Connection à la base sysdba masterkey read_only C:\AWRoot\bin\common\..\..\dtrd\database\FLOWCHART_CONTEXT.FDB 3156: Erreur dans CDataBase::Connect : Database is probably already opened by another engine instance in another Windows session 3156: => Unsuccessful execution caused by a system error that precludes successful execution of subsequent statements ----- Two connections are ok but the third seems locked. Only one thread and exe, uused in admin mode, are querring this database. We use FireBird 2.5.0 in emmbedded mode. With the super mode (client / server with windows services) no problems are raised. To continue our test we decide to develop a test software (connection - querry - deconnection endlessly). Using an instance of this software in admin mode and another instance in normal mode at same time with firebird in embedded mode causes the same error « Database is probably already opened by another engine instance in another Windows session » Is there a way to use embedded server with two softwares launched with different windows grant ? Database is opel with options : *dpb++ = isc_dpb_version1; *dpb++ = isc_dpb_num_buffers; *dpb++ = 1; *dpb++ = 90; *dpb++ = isc_dpb_force_write; *dpb++ = 1; *dpb++ = 0; Regards.
