 ## Overview
 
 Enduro/X is Open Source Middleware Platform for Distributed Transaction 
 Processing
 
 It is modern, micro-services based middleware for writing distributed, open
 systems (program consists of several executables) based applications. Thus 
 by using Enduro/X programmers do not have to worry about threads and concurrency 
 anymore, the load balancing and multi-CPU loading is done by Enduro/X middleware by it self,
 administrator only have to determine how many copies of particular services should
 be started. Of-course Enduro/X supports multi-threaded applications too, but now
 system architects have a choice either to design multi-threaded executables or
 just configure number of executables to start.
 
 For local inter-process-communication (IPC) Enduro/X uses kernel memory based Posix
 queues to avoid overhead of the TCP/IP protocol which is used in other middlewares
 or REST based micro-service architectures. Thus this approach greatly increases
 application speed, as kernel queues is basically a matter of block memory
 copy from one process to another (by contrast of 7 layers of TCP/IP stack and
 streaming nature of the sockets vs block copy). 
 
 Enduro/X provides SOA architecture for C/C++ applications and allows to cluster 
 application in fault tolerant way over multiple physical servers. 
 Enduro/X provides Oracle(R) Tuxedo(R) FML/FML32 library emulation, 
 including boolean expressions. Other Tuxedo specific APIs are supported, 
 such as tpforward() and work with distributed transactions (tpbegin(), 
 tpcommit(), etc.).
 
 Platform provides X/Open XATMI and XA interfaces/APIs for C/C++ applications. Enduro/X can 
 at some level can be considered as replacement 
 for Oracle(R) Tuxedo(R), Jboss Blacktie (Narayan), Hitachi OpenTP1 and other XATMI middlewares.
 
 Dual licensed under Affero General Public License Version 3 for use in Open
 Source project or Commercial license Acquired from Mavimax Ltd

 EnduroX have bindings for:
 - Golang (client & server)
 - Java (client & server)
 - Python 3 (client & server)
 - PHP (client)
 - Perl (client & server)
 
 Enduro/X provides following features:
 
 * Standards based APIs - SCA, The Open Group XATMI
 Communication types - Synchronous, Asynchronous, Conversational, Publish/subscribe
 * Typed buffers
   * UBF (Unified Buffer Format) which provides emulation of Tuxedo's FML/FML32 
         format. UBF if high performance binary protocol buffer format. Buffer is 
         indexed by binary search on fixed data types. Types supported include BFLD_CHAR,
         BFLD_SHORT, BFLD_LONG, BFLD_FLOAT, BFLD_DOUBLE, BFLD_STRING, BFLD_CARRAY,
         BFLD_PTR, BFLD_UBF (recursive buffers), BFLD_VIEW
   * STRING buffer format.
   * CARRAY (byte array) buffer format.
   * JSON buffer format, automatic conversion between JSON and UBF available.
   * VIEW buffer (starting from version 5.0+). This offer C structure sending
         between processes in cross platform way. Also this allows to map UBF 
         fields to VIEW fields, thus helping developer quicker to develop applications, 
         by combining UBF and VIEW buffers.
 * Transaction Management - Global Transactions - Two-phase commit protocol - X/Open XA
 * Clustering - on peer-to-peer basis
 * Multi-threaded Event broker (also called publish and subscribe messaging)
 * System process monitoring and self healing (pings and restarts)
 * SOA Service cache. XATMI services can be cached to LMDB database. Resulting 
         that next call to service from any local client receives results 
         directly from cache (mainly from direct memory read).
 * Dynamic re-configuration
 * Custom server polling extensions
 * XATMI sub-system is able to work without main application server daemon (ndrxd)
 * Main application server daemon (ndrxd) can be restarted (if crashed). 
         When started back it enters in learning mode for some period of time, 
         in which in gathers information about system, what services are running, 
         etc. After learning =-period, it starts to do normal operations
 * tpforward() call
 * ATMI server threads may become clients, and can do tpcall()
 * Extensive logging & debugging. Enduro/X logging can be configured per binary 
         with different log levels. As ATMI servers can be started outside of 
         appserver, it is possible to debug them from programming IDE or with 
         tools like valgrind.
 * For quality assurance project uses automated unit-testing and integration-testing
 * Built in ATMI service profiling.
 * Environment variables can be updated for XATMI server processes with 
         out full application reboot.
 * Generic client process monitor (cpm). Subsystem allows to start/stop/monitor 
         client executables. At client process crashes, cpm will start it back.
 * Starting with version 5.2 Enduro/X provides configuration data encryption feature, 
         so that software which is built on top of Enduro/X may comply with 
         Payment Card Industry Data Security Standard (PCI/DSS).
 * Application monitoring with TM_MIB interface. For example NetXMS.
 * XA Driver for PostgreSQL.
 * Fully functional buildserver, buildclient, buildtms tools.
 * Provides server entry point _tmstartserver().
 * Multi-threaded dispatcher support (mindispatchthreads/maxdispatchthreads),
         including support for tpsvrthrinit() tpsvrthrdone() callbacks.
 * Fast Pool Allocator - for performance reasons malloc results are cached, 
         so that blocks can be re-used instead of doing malloc again, thus Enduro/X
         is gaining overall performance.
 * Support of writing server daemons for multi-threaded servers 
         i.e. tpacall() to self advertised services during tpsvrinit().
 * Support of Data Dependent Routing for UBF buffers.
 * XATMI service auto-transactions are supported.
 * For Linux and FreeBSD platforms call priorities are supported.
 * Enduro/X logger now supports log-rotate calls (to re-open log handles) during
 the runtime.
 * Enduro/X logger now allows to change log levels on the fly for any Enduro/X
 related process.
 * Enduro/X provides Latent Command Framework (LCF), where developers via 
 plugin interface can publish CLI commands in xadmin tool, while any Enduro/X related
 program can receive such commands via callback and perform custom action.
 * Has tpsetcallinfo() and tpgetcallinfo() APIs.
 * Product is extensively documented.
 * Tool for automatic configuration migration from Oracle Tuxedo to Enduro/X.

 # Load balancing
 
 ![Alt text](doc/endurox-load-balance.jpg?raw=true "Enduro/x service load 
 balancer")
 
 Supported operating system: GNU/Linux, starting from 2.6.12 kernel 
 (needed for POSIX Queues). Starting with Enduro/X Version 3.1.2 IBM AIX (6.1 and 
 7.1), 
 Oracle Solaris 11, MAC OS X (experimental) and Cygwin (experimental) 
 support is added. Supported compilers: gcc, LLVM clang, IBM xlC.

 # Call/message forwarding
 
 ## Instead of doing calls to each server separately...
 
 ![Alt text](doc/exforward_tpcall.png?raw=true "Classical service orchestration")
 
 This is typciall way for example if doing micro-services with HTTP/REST. 
 You need to do the calls to each service separately. And that is extra 
 overhead to system (multiple returns) and the caller must orchestrate the all 
 calls.
 
 ## ...Enduro/X offers much effective way - tpforward() where request is 
 passed around the system
 
 ![Alt text](doc/exforward_forward.png?raw=true "Enhanced service 
 orchestration by forwarding the call")
 
 In this case the destination service orchestrates the system, it is up to 
 service to choose the next service which will continue the call processing. 
 The caller is not aware of final service which will do the reply back 
 (tpreturn()).
 
 Note that service after doing "tpforward()" becomes idle and can consume next 
 call.
 
 # High availability and self healing
 
 Enduro/X is capable of detecting stalled/hanged XATMI servers and gracefully 
 can reboot them. The ping times are configurable on per server basis. In case 
 if main daemon dies, it is possible to configure special XATMI server named 
 "tprecover" which monitors "ndrxd" and vice versa, ndrxd can monitor tprecover. 
 Thus if any of these services are not cleanly shut down, then system will 
 heal it self, and boot service/daemons back.
 
 The ndrxd learning mode is some period of time (configurable) in which ndrxd 
 will request all the system for active servers and their services, 
 to get back the view of the system and be in control. Note that system is able 
 to work even without ndrxd, but at that time no server healing 
 and management will be done.
 
 ![Alt text](doc/server_monitoring_and_recovery.png?raw=true "Enduro/X high 
 availability facility")
 
 # Real time system patching
 
 It is possible to patch the Enduro/X system (update stateless XATMI servers) 
 without service interruption. This is achieved by following scheme:
 
 ![Alt text](doc/rt-patching.png?raw=true "Enduro/X real time patching")
 
 # Monitoring
 
 Enduro/X provides TM_MIB API for information reading. Out of the box NetXMS 
 monitoring suite uses this API to monitor application. Thus full featured
 monitoring is possible. Presentation here (video):
 
 [![Enduro/X monitoring with NetXMS](https://img.youtube.com/vi/ubJk27bjKGE/0.jpg)](https://www.youtube.com/watch?v=ubJk27bjKGE)
 
 # Performance
 
 Due to fact that Enduro/X uses memory based queues, performance numbers are 
 quite high:
 
 ## ATMI client calls server in async way (tpacall(), no reply from server)
 
 ![Alt text](doc/benchmark/04_tpacall.png?raw=true "Local tpcall() performance")
 
 
 ## Local one client calls server, and gets back response:
 
 ![Alt text](doc/benchmark/01_tpcall.png?raw=true "Local tpcall() performance")
 
 ## Multiple clients calls multiple servers
 
 ![Alt text](doc/benchmark/03_tpcall_threads.png?raw=true "Multiprocessing 
 tpcall() performance")
 
 ## Single client calls single server via network (two app servers bridged)
 
 ![Alt text](doc/benchmark/02_tpcall_network.png?raw=true "Network tpcall() 
 performance")
 
 ## Persistent storage (message enqueue to disk via tpenqueue())
 The number here are lower because messages are being saved to disk. 
 Also internally XA transaction is used, which also requires logging to stable 
 storage. This benchmark uses default Enduro/X setting for data
 flushing to disk which is fflush() Unix system call. Fflush() does not guarantee data
 consistence at power outage event. For fully guaranteed data consistence, 
 flags (FSYNC/FDATASYNC/DSYNC) can be set for XA resource. However expect much 
 lower TPS performance.
 
 ![Alt text](doc/benchmark/05_persistent_storage.png?raw=true "Network 
 tpenqueue() performance")
 
 
 ## Tpcall cache benchmark
 This benchmark shows the performance of cached XATMI service calls.
 
 ![Alt text](doc/benchmark/06_tpcache.png?raw=true "tpcall() cache performance")
 
 # Migration from Oracle Tuxedo to Enduro/X
 
 The migration is as simple as this (ideal scenario):
 
 * Re-build the source code against Enduro/X.
 * Migrate the configuration to Enduro/X format in seconds with [ubb2ex](doc/manpage/ubb2ex.adoc) tool.
 * Test migrated application.
 * Go live.
 * See full [migration_tuxedo](doc/migration_tuxedo.adoc) guide.
 
 Configuration migration example (ubb_config1 is Tuxedo UBB configuration file):
 
 ```
 $ ubb2ex ubb_config1 -P ./test_dir
