Replication Components
The following is a description and list of all Adabas Event Replicator for LUW components:

CONNX Message Queue
cnxmq
connx/replicator/common
mqserver script in the connx directory
connx/replicator/log/
cnxmq_run.log
A message queue needs to be running on each system that contains replication components.
CONNX Replication Controller
cnxcontrol
connx/replicator/consumer
eventserver script in the connx directory
connx/replicator/log/
CTRL.log
CONNX Event Consumer (EC)
cnxrep
connx/replicator/consumer
Controller (cnxcontrol)
connx/replicator/log/
EC_<source>_<target>.log
Used only with replications that have a relational target. Is not used with Adabas to Adabas replication. There will be one cnxrep process running for each source database/target database combination.
EP Configuration Helper
cnxepcfg_64
connx/replicator/producer
the EP (libcnxepada_64)
connx/replicator/log/
EP_CONFIG.log
Invoked by the first replication enabled nucleus to be started and stays up until the last replication enabled nucleus is shut down. This process is a helper of the EP and is not the actual EP. The EP communicates with this process via TCP/IP on port 9207.
CONNX Event Producer (EP)
libcnxepada_64.so*
connx/replicator/producer
shared library loaded into the Adabas nucleus process space
connx/replicator/log/
EP_<dbid>.log
The EP is shared library and not a stand alone process. It is loaded by the Adabas nucleus when the nucleus has been enabled for replication. The EP is responsible for starting the cnxepcfg_64helper process.
Note: 
* on AIX systems, the EP has an extension of .a rather than .so
In addition to the above Replication Components, the CONNX Adabas Data Server components are also installed on the EP machine (and possibly the Target Databas machine). The Data Server components are:

CONNX Listener
cnxrun
connx/
connxserver script in the connx directory
connx/cnxrun.log
The Adabas Data Server is made up of a Listener and Server component. cnxrun is the listener component
CONNX Server
cnxadaC0
connx/
cnxrun
connx/cnxrun.log
A separate cnxadaC0 process is started for each connection made to Adabas from a CONNX client. The number of running cnxadaC0 process will be dependant on the number of active connections to the database.

EP Configuration Helper
cnxepcfg.exe

the EP
c:\connx32\replication\log\
EP_CONFIG.log
Invoked by the first replication enabled nucleus to be started and stays up until the last replication enabled nucleus is shut down. This process is a helper of the EP and is not the actual EP. The EP communicates with this process via TCP/IP on port 9207.
CONNX Event Producer (EP)
cnxepada64.dll
c:\connx32\replication\producer

c:\connx32\replication\log\
EP_<dbid>.log
The EP is shared library and not a stand alone process. It is loaded by the Adabas nucleus when the nucleus has been enabled for replication. The EP is responsible for starting the cnxepcfg helper process.

Enterprise Server Service (CONNX Listener)
cnxremote.exe
c:\connx32\cnxremote\bin
Windows Service
c:\connx32\cnxremote.log
The Adabas Data Server is made up of a Listener and Server component. cnxremote is the listener component on Windows
CONNX Server
cnxadabas.dll
c:\windows\system32
cnxremote or loaded directly into CONNX client depending on configuration
c:\connx32\cnxremote.log
A separate server thread is started for each connection made to Adabas from a CONNX client. The number of threads will be dependant on the number of active connections to the database.
