multiple ORACLE Documaker instances reading single jms/hornetq issue.

Documaker's snail waxed zero size PDF's on our production environment, and it took me a day to figure it out, whats wrong with it! :(

below is the setup we had in our production environment.

whats happening here is, that two Documaker instances are reading from single/same jms/hornetq queue, and as Documaker does not have any identifier mechanism for soap messages, as it seems both tries to hold the message and somehow destroys the soap message arrived from ETPM in jms queue, so both Documaker instances endup with generating ZERO size PDF's.

the workaround is to run single Documaker instance per jms/hornetq queue. But this way you d'nt have real time fail-over for Documaker, you have to do manual switching in case of failure!

cheers.

ETPM, Documaker, JMS, LDAP, Database, Conceptual and abstract workflow diagram

ladies, if you are unable to understand how ORACLE ETPM, ORACLE Documaker, JMS/HornetQ, LDAP/OpenDS and Database/Exadata should work together, here is the lazy drawn diagram, i hope you will get an idea about what i have been implementing recently :)

you may consider it as ETPM application data center conceptual design as well;

step by step tomcat on ETPM App Server

ok, i know it has been overwritten, but i had to dump it somewhere and blog is the best place to leave my ETPM snail wax! :)


step 01: [amadm@etpm-hostname ~]$ cd /opt/tomapp  --- tomcat installation base directory

step 02: download latest tomcat release from http://tomcat.apache.org/download-70.cgi

step 03: copy apache-tomcat-7.0.27.tar.gz to /opt/tomapp

step 04: verify if downloaded file is correct.

[amadm@etpm-hostname  ~]$ md5sum apache-tomcat-7.0.27.tar.gz
486769ec1094fb45f000d30f237b3643  apache-tomcat-7.0.27.tar.gz

now compare the value with http://www.apache.org/dist/tomcat/tomcat-7/v7.0.27/bin/apache-tomcat-7.0.27.tar.gz.md5
if both values are same, it mean download is correct.

step 05: [amadm@etpm-hostname  ~]$ tar xvf apache-tomcat-7.0.27.tar.gz

step 06: create link:

[amadm@etpm-hostname  ~]$ ln -s apache-tomcat-7.0.27 apache-tomcat

step 07: start & stop tomcat

[amadm@etpm-hostname bin]$ cd /opt/tomapp/apache-tomcat/bin/
[amadm@etpm-hostname bin]$ ./startup.sh
[amadm@etpm-hostname bin]$ ./shutdown.sh

The root LoggedException was: Error setting oracle NLS Date format

Ok baby! you are receiving NLS Format error in ETPM or CC&B logs? and you want to know whats going on with your Application Server? ok ok... here we go!

ORACLE Enterprise Taxation and Policy Management has bug i.e. once it lost connection to database server, unable to reset it seemingly less, and during this time when it tries to recover the connection between Application Server & Database server, it start giving HTTP-500 error on user's browser.


As you will continue to receive NLS Format error in logs, while it has nothing directly related to connectivity issue you will remain confuse, in our case we had the same issue, but later ORACLE informed us that they are working on this bug. I hope it will be fixed pretty soon!


in our case the connect drop was caused due to our CISCO PIX/Firewall server, it had some rules which were causing connection drop between Application Server & Database server.


After eliminating this connection drop issue, we were able to work smoothly and waiting for ORACLE to produce bug fix!


cheers
