Nirva

New feature: Adding an optional http log file for client connectors using the nvc dll.

New feature: Possibility to restrict a web service access to HTTPS protocol only.

New feature: Possibility to use client certificates with HTTPS. This is used for authorizing access to trusted users but not for authentication.

Bug correction: In web service, using the same message as both input and output generates an error message when building the WSDL. There is now an error message when saving the web service content in order to prevent such situation (using a message for both input and output stays forbidden, even for different operations).

Bug correction: Possible exception when a command executes a procedure in another session itself sending command back to the parent session.

Nirva

Bug correction: The NV_NEW_IF_EXPIRED parameter was returning a session not found error instead of creating a new session.

Bug correction: A command to a service in the init of an application may crash the server if the service issues a nirva command in its session cleanup code. For current Nirva systems services this may occur only in the database service version 2.35.

Bug correction: The AIX version may crash if an xslt contains a numeric comparison in a test.

Bug correction: Bug in the access to service or application containers. In some rare situations, the container of the command may not be the requested one but the one used by the previous command. This bug doesn’t occur on session containers or registry.

Bug correction: User registries defined on a remote directory under windows were not working.

Bug correction: Big perl script files (>1Mb) may crash Nirva. The bug is inside the perl code itself and cannot be removed but Nirva now generates an error in this case instead of crashing. Anyway, this is not a good practice to have perl procedure greater than 1 Mb.

Modification: The session information is not given any more in the XML fault message when the session has been closed.

Modification: The license management is now in a specific library. If this library is not found, the licenses cannot be controlled and the system acts like if there were no license.

Nirva

Bug correction: The encoding (utf-8 or iso8859-1) of some client connectors were not taken correctly in care. This concerns all the clients using the nvc client library so this includes the java and dotnet client connectors. In order to correct this bug, both client and server should be changed to this version.

Bug correction: In some very rare situations, some tasks may stay in the “In queue” state. A check has been added in order to resume the task in this case.

New feature: Adding a cache for xslt files to improve performance.

New feature: Front-end load balancing for web connectors (browser, web service, xml and soap connectors). Some redirection servers can be defined at application level in order to load balance requests.

Nirva

Bug correction: Defining a listener with an open procedure may crash Nirva. This bug occurs only on 3.0.008 version.

Bug correction: Possible compatibility issues with the recompiled perl on windows version 3.0.008 so we came back to a perl compiled with an older compiler (only the perl part is concerned, nirva is still compiled with the visual C++ 2008 compiler).

Bug correction: Under windows, hardware exception was not handled correctly (occurs in 3.0.008 only).

3.0.009

20/12/2009

Bug correction: Possible deadlock when requesting a command to be executed by another session from a procedure a service (This does not occur with named sessions).

Modification: Compiled on a new compiler under windows (visual C++ 2008). Compatibility issue: this may require installation of Microsoft redistributable package for Visual C++ 2008 on some old windows OS (ex: windows 2003 server). This package can be found at http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf&displaylang=en

Bug correction: The alias path was forced in lowercase making some directories unreachable under Unix.

Bug correction: the TABLE_MODIFY_COLUMN was not returning error in case of error.

Bug correction: the TABLE_SEARCH MAXDOCS parameter was not working with a query equal to “*”.

Modification: Affinity management for the number of processors. Nirva takes care of the number of processors dedicated to its process and doesn’t enter in demonstration mode if this matches the number of processors of the license. This is not available on AIX. Under Windows and Linux, the affinity is automatically set by Nirva following the number of processors of the license. Under Solaris and HPUX, the affinity must be set externally by using processors sets.

Modification: Adding virtual printer connector in the Nirva distribution. Documentation for this connector is available separately.

New feature: Threaded sessions. A new THREAD class allows creating a session for executing a procedure in separate thread.

New feature: 64 bits version of the nvc client dll for the x64 windows platform. This also allows using the java connector with 64 bits jvm for the windows x64 platform.

This allows procedure or service commands returning string information directly accessible without having to create an object. This is done by a new command of the COMMAND class named SET_OUTPUT_BUFFER.

New feature: Adding a stack of commands and procedures at session level. This helps debugging applications.

3.0.007

14/10/2009

Nirva

Bug correction: Table object numeric fields were using float instead of double type internally, so the maximum value was 8 388 608. With a double type, This maximum integer value has been increased to 4 503 599 627 370 496. For information the table numeric field contains a string and the conversion to a number occurs only for the TABLE_SEARCH and TABLE_DELETE_ROWS commands. So only these commands may be affected by this bug.

3.0.006

09/10/2008

Ndas

New feature: New service NDAS (Nirva Directory Access Service). This service allows Nirva applications to authenticate their users against an LDAP server.

Once NDAS has authenticated a user, it can then assign Nirva permissions to the user session.

This is a Nirva security service that replaces the internal Nirva security management.

The NDAS service is provided by our partner Docuplus Ltd.

Bug correction: Http end of line was set to LF instead of CRLF. This may produce error messages on some web service clients even if most of them accept the single LF.

Bug correction: When a command from a service returns successfully but some error information has been set by the service (using SetError or SetErroEx), then the console was displaying this error message. Now the error information is correctly cleared if the service command is successful.

Modification: Management of multiple attachments in the MAIL:SEND command.

Modification: Adding a parameter in web services allowing to set the namespace prefix and to deploy it.

Modification: In the WebSphere MQ connector the expiry parameter of the output message is now inherited from the expiry value of the input message.

17/11/2006

Database service

Bug correction: the test of nullability when adding records was inverted. This could produce a long SELECT order before adding records especially in tables having no nullable fields. The test is now made in the correct way so the select is made on the first not nullable field by requesting records having this field equal to NULL. This produces a fast request since the resultset can have only 0 records.

2.25

Modification: The CONTAINER:VIEW command was not working as described in the documentation. The INFO object parameter was always set to the value “INFO” whatever the value of the INFO parameter.

Modification: The GetError command from java service, java procedures or perl procedures was not working as described in the documentation. The value “DESCRIPTION” was not returning the DESCRIPTION of the error. For getting the description it was necessary to request “DESC”. Now both “DESC” and “DESCRIPTION” return the description of the error.

Bug correction: few commands may not correctly report an error. The error is displayed in the console but the command returns ok when call from perl or java. This concerns the commands TABLE_REMOVE_ROWS, TABLE_CLEAR_ROWS, TABLE_MODIFY_COLUMN, SECURITY:LOAD_USER_CONTEXT SECURITY:SAVE_USER_CONTEXT
