Enduro/X 8.0 Release

Added by Editor over 2 years ago

Overview

This is major strategic release. New release includes several overall improvements for the system stability, compatibility and performance. Major feature implemented is support for sub-UBF buffers (recursive buffers), support for PTR type fields in UBF and VIEW fields in UBF. New APIs have been added tpsetcallinfo() and tpgetcallinfo(). Platform independent network protocol mode for tpbridge has been refactored and receives performance boost as well as release includes full protocol description document. Another big feature for this release is inclusion of new tool "ubb2ex" which allows to perform automatic Oracle Tuxedo configuration file migration to Enduro/X format in matter of seconds. Tool performs best possible mapping to Enduro/X configuration, including, support for clustering, persistent queues, servers, services, routing. Migration document has been created which describes how manually to migrate from Oracle Tuxedo to Enduro/X. With this version AIX 7.3 builds are provided.

API changes

New APIs:

  • tpsetcallinfo()
  • tpgetcallinfo()
  • Bgetr(), Bgetrv(), CBgetr(), CBgetrv(), Bfindr(), Bfindrv(), CBfindr(), CBfindrv(), Bpresr(), Bpresrv(), CBvgetr(), CBvgetrv(), CBgetallocr(), CBgetallocrv(), Bvnullr(), Bvnullrv(), CBvgetallocr(), CBvgetallocrv() - for quick recursive field access

WARNING: Any UBF buffers saved as blobs shall be completed prior upgrade, due to UBF internal structure changes.

WARNING: Application must be re-built if migrating from 7.5, 7.0 or earlier Enduro/X version.

Enduro/X 7.5 Release

Added by Editor about 3 years ago

Overview

This is major strategic release. Major changes in this release is that, there is no more requirements of the large process stack are. Now Enduro/X uses dynamic allocated memory for internal buffer management. To keep the performance levels high, Enduro/X employs Fast Pool Allocator (FPA) which caches certain sizes of allocated memory blocks, so that lot of malloc() calls are eliminated. Previously new thread stack size was based on message size factor estimations. Now NDRX_THREADSTACKSIZE environment variable is used for this purposes (and if not sent default 8M is used). Other news is that this version implements more compliant build tools, including buildserver, buildclient and buildtms tools. Now buildserver generates the main() entry points of the server processes. Also when generating, main function, automatic service advertise is provided too. Build tools includes '-r' flag for static XA resource manager symbol application, thus for these cases libndrxxatmsx.so driver shall be used to use built-in xa switch handler.

New version of Enduro/X supports XATMI dispatcher multi-threading, supports callbacks of tpsvrthrinit() and tpsvrthrdone() via _tmstartserver(). Enduro/X event dispatching server tpevsrv is upgraded to multi-thread support via mindispatchthreads/maxdispatchthreads settings.

With this release Data Dependent Routing (DDR) support has been introduced. With DDR service call priority handling is added (only for Linux and FreeBSD), as well auto-transactions are added for XATMI services. See ndrxconfig.xml(5) manage for configuration details.

This version introduces new framework - Latent Command Frameworks - which allows to publish certain commands in shared memory and Enduro/X libraries processes these commands at debug points (which are in many places in Enduro/X). The published command checking is done very efficiency and does not introduce any overhead. With help of these commands now in the real-time logging configuration for processes can be changed and also loss-less logrotate can be performed. Framework allows for developers to publish custom commands to processes via plugin interface and such new API commands as: ndrx_lcf_func_add(), ndrx_lcf_xadmin_add(). With this LCF framework new shared memory segment is open by Enduro/X at startup. After the shutdown the shared memory segment is kept open (but all command data is reset). To fully remove all shared memory segments, use xadmin down -y command.

UBF Buffer now is optimized for BFLD_STRING field handling. The UBF buffer internally caches the string length, previously any iteration over the UBF buffer made strlen() for each string field occurrence, now cached length is used.

Generic System V mode has been reworked. Instead of previously using internal unnamed was utilized on every timed message processing. Now System V time-out scanning thread wakes ups every NDRX_SCANUNIT milliseconds, checking for queue thread time-out. This boost performance for System-V as no other internal message roundtrip is needed, but now periodic wakups are performed by XATMI processes for time-out scanning.

Thanks to IBM AIX extension now polling on System-V queues are performed in the same fashion as it is done on Linux.

Due to poor performance, and fact that no customers are using GPG-ME bridge traffic encryption, this functions is removed from the tpbridge process.

PDF documentation is removed from build processes, and binary distributions which includes documentation release, now includes HTML only documents.

For better analysis, logging is moved to microseconds format.

With this release, new endurox-connect version 2.5.x is released, which includes Distributed Transaction orchestration API over the web services. endurox-connect v2.5.x is not compatible with earlier Enduro/X versions.

API changes

  • BF_LENGTH/F_LENGTH value is changed from 32 to 64 (Max UBF field length)
  • _tmstartserver() added arguments to tmsvrargs_t for p_tpsvrthrinit/p_tpsvrthrdone

ABI changes

  • UBF buffer format changes due to string len caching. Thus any binary blob saved from previous Enduro/X version will not work in new version (if there are string fields)
  • If server processes are started by _tmstartserver(), then there might be possible segmentation fault, as new Enduro/X version probes for tmsvrargs_t for p_tpsvrthrinit/p_tpsvrthrdone fields. If _tmstartserver() was not used, then there are no ABI changes to this aspect.
  • If programs were using Enduro/X logging framework via ndebug.h provided macros, applications needs to be re-built. This also applies to any modules which were using endurox-go.
