mongo to JsonListener to informix

Posted By: FRANK
Date: Tuesday, 20 January 2015, at 4:47 p.m.

HI,

We are testing Mongodb shell talking to Informix 12.10 FC4.

Program Name: onstat
Build Version: 12.10.FC4W1X1
Build Number: N028
Build Host: lxvm-l172
Build OS: Linux 2.6.18-128.el5
Build Date: Tue Sep 16 15:07:24 CDT 2014
Build Timestamp: 16-Sep-2014.14:53:46UTC-05
GLS Version: glslib-6.00.FC4

my jsonListener.properties is configured as ,

url=jdbc:informix-sqli://localhost:9113/sysmaster:INFORMIXSERVER=nsofops_tcp;USER=informix;PASSWORD=xxxxx

update.client.strategy=deleteInsert

sharding.enable=true

security.sql.passthrough=true

listener.port=27017

database.dbspace=dbdw0

9113 is the port number of informix server nsofops_tcp.

I started JsonListener, it looks fine,

---console command and output :
[informix@maggie bin]$ java -jar /usr/informix/bin/jsonListener.jar
-config /usr/informix/etc/jsonListener.properties -logfile
/dbbackup/info/json/jsonlisten.log -start
starting mongo listener on port 27017

---JsonListener log:
2015-01-20 20:56:47 [JsonListener-1] INFO
com.ibm.nosql.informix.server.mongo.MongoListener - JSON server listening
on port: 27017, 0.0.0.0/0.0.0.0

Then I started mongo shell,

---console command and output :
[informix@maggie bin]$ mongo
MongoDB shell version: 2.6.7
connecting to: test
mongos>

---JsonListener log:

2015-01-20 21:00:41 [JsonListener-1] INFO
com.ibm.nosql.informix.server.mongo.MongoListener - connection accepted
from /127.0.0.1:41140
2015-01-20 21:00:41 [JsonListener-1-thread-1] INFO
com.ibm.nosql.informix.server.mongo.MongoListenerMessageHandler -
connection accepted from: 127.0.0.1:41140 , sessionNumer: 1 ,
listenerNumber: 8

Seems so far so good.

But .... When I run mongo shell command,

---console command and output :
mongos> show dbs
2015-01-20T21:41:09.428+0000 listDatabases failed:{

"code" : null,

"ok" : 0,

I do not see any info of connection request rejected in Iinformix online
log. So, it seems the JsonListener did not even try to connect to infomix.

Any idea or comments ?

Thanks
Frank
