Hi
I am getting this alert "JCO_COMMUNICATION_FAILURE error text:
"COMMUNICATION FAILURE" during JCo
call. Error when opening an RFC
connection"
System:BXP
Segment:SAP_CCMS_az18u158_BXP_01
MTE:BXP\IEngine_BXP_997 Integration
Server\Category MAPPING\Message alerts
by Error Codes
Please tell how to solve this alert
regards
rao
First, could you please do the following check:
1) Call SM59, check RFC destinations: AI_RUNTIME_JCOSERVER and
AI_DIRECTORY_JCOSERVER, what is the Program ID under Registered
Server Program section?
2) Call J2EE visual admin, choose cluster -> server -> JCO RFC provider
there should be AI_RUNTIME_<SID> and AI_DIRECTORY_<SID> under
available RFC destination tab. Please make sure their names are the
same as the program ID registered in AI_RUNTIME_JCOSERVER and
AI_DIRECTORY_JCOSERVER respectively.
3) Also make sure the gateway host and service are the same in both
RFC configurations.
Can you perform an R/3 trace for this issue aswell - to trace the
RFC connection issue? It maybe that there is an error like
"timeout during allocate of registered program" which is likely with
this type of message in SXMB_MONI. (SAP Note No. 84850)
1) set gw/reg_timeout to a higher value
2) check/change current Queue and Mapping Configuration/Setup
the parallel number of XI outbound queues (XBTO* queues) is
set in XI configuration (SXMB_ADM); setting EO_OUTBOUND_PARALLEL
to e.g. 20 allows 20 messages to be mapped in parallel;
this queue number multiplies by the number of different
configured receivers
#receivers * EO_OUTBOUND_PARALLEL should correspond to the number
of parallel configured mapping threads (J2EE Visual Admin,
service JCo Rfc Provider, Destination AI_RUNTIME_*, #processes)
if ( #used-outbound-queues > #jco-mapping-threads ) then this
can cause the above seen timeout error
=> consequence check/change parameter EO_OUTBOUND_PARALLEL or
JCo mapping threads (processes)
Finally, if you are perhaps running on AIX, then check note 716927
Otherwise tell which OS do you run on

Hey
in sm59 under TCP/IP connections just check the connectivity of AI_DIRECTORY_JCOSERVER and AI_RUNTIME-JCOSERVER
thanx
