Chapter 1 . New Features in Release 6.4

Introduction

BEA TUXEDO Release 6.4 includes the following enhancements:

Improved performance of Domains gateway processes
Improved BRIDGE processing using multiple network addresses
New error detail APIs
Improved system availability through a configurable mechanism to detect lost connections between /Workstation clients and servers
Additional enhancements including improved service time-out error reporting
Integrated development environment on Windows NT

Release v6.4 also provides support for 10 additional platforms and resolutions to over 200 requests. (For changes to the software and documentation, see Chapter 5).

Note: Refer to the BEA TUXEDO v6.4 Addendum Guide for detailed information on each enhancement.

Improved Domains Performance

This release improves the performance of the Domains gateway processes. Bottle- necks for network message traffic in the BEA TUXEDO system have been reduced significantly. This performance improvement is evident on all supported BEA TUXEDO Release 6.4 platforms.

Improved BRIDGE Processing

BEA TUXEDO v6.4 includes the following improvements to BRIDGE processing:

Redundant hardware configurations are leveraged.
Connectivity is improved.
Multiple network addresses can be used (that is, multiple communication channels can be used simultaneously).
Asynchronous reconnection of network links is supported.

New Error Detail APIs

Release 6.4 includes two new error detail APIs that return more refined error codes: tperrordetail and tpstrerrordetail:

tperrordetail returns additional detail related to an error produced by the last BEA TUXEDO routine called in the current thread. It returns a numeric value that is also represented by a symbolic name. If the last BEA TUXEDO routine called in the current thread did not produce an error, then it returns zero. Therefore, tperrordetail should be called only after an error has been indicated; that is, when tperrno has been set.
tpstrerrordetail is used to retrieve the text of an error detail of a System/T error. BEA TUXEDO calls this API whenever an application requires the default error detail string associated with the numeric or symbolic representation of an error detail. You can use the returned pointer as an argument to userlog or fprintf or any other API that processes a string.

Improved System Availability Using WorkStation Client Time-Out

This release provides a configurable, client-side mechanism to detect (through the WSH) lost connections between /WS clients and servers. The mechanism returns an appropriately descriptive error code to the user. Supported on all /WS platforms, this feature improves system availability for users and makes it easier for programmers to implement recovery strategies.

Additional Enhancements

The following enhancements have been included in this release:

Reporting of Service Time-Out Errors
Default Device for TLI added
Domain ID on the Server Command Line

Resolutions to all outstanding high severity MRs (modification requests) and CRs (change requests) have been incorporated in this release.

Integrated Development Environment on Windows NT

In Release 6.4, BEA TUXEDO offers a new integrated development environment (IDE) for Windows 95 and all currently supported Windows NT environments (Intel and Alpha). The IDE allows you to integrate a BEA TUXEDO application into a Microsoft Visual C++ (msdev) environment. (When the integration is not possible, BEA TUXEDO creates a virtual IDE by emulating the functionality of msdev.) The IDE makes it easier for you to develop BEA TUXEDO enabled applications for 16-bit and 32-bit Windows operating systems.
