Project Life Cycle



What are the cNIS pre-requisites to perform IP network discovery? Do I need to be directly connected to a router port or it can be done remotely?
All you need is the remote access to router(s) via SNMP protocol (SSH protocol is not mandatory). You must know routers' IP addresses and community names (optionally login and password for shell logging). All this information should be put to cNIS configuration files

I set the proper path to configuration files and check that files exist but cNIS does not run?
Ensure that you have read access to the configuration file from Tomcat user context (check the permissions given to the system account, where Tomcat runs).

I have access to my database from the Tomcat application but GFX installer displays a warning "Could not connect to the database".
Tomcat and the database are installed probably on a remote host, and you don't have access to this machine (or a particular service) from the localhost. Please use command line installer to install cNIS or enable access to the database (and Tomcat if necessary) from the local machine.

Why IP discovery doesn't work after successful installation?
IP network explorer needs an XML file with routers' description. A directory, where IP network explorer is looking for this file is choosen during graphical installation . After installation you can check this location in cnis-ne-plugins.xml file in TOMCAT_HOME/webapps/cma/WEB-INF/conf directory. You can find schema of the file with routers' description in the cNIS Install Guide


Where can I find cNIS configuration files to modify a selected property?
Configuration files are delivered with WAR files and available in the TOMCAT_HOME/webapps/<cNIS application>/WEB-INF/conf directory after installing cNIS. For example, to change notification properties edit the file TOMCAT_HOME/webapps/cma/WEB-INF/conf/

I changed the configuration of cNIS application but I cannot see any effects.
After changing any settings in the config files the Tomcat context should be restarted for these changes to take effect.

Where can I find log files of cNIS applications?
Place, where log files are stored is chosen during graphical installation. Path to log file is written in TOMCAT_HOME/webapps/<CNIS_APPLICATION>/WEB-INF/conf/ file. In standard configuration logs are also written to TOMCAT_HOME/webapps/<CNIS_APPLICATION>/WEB-INF/logs/catalina.out file. See cNIS System Guide for more details

I prepared the routers configuration file and tried to explore the IP network but it finishes with the SNMP timeout error (which could be found in the catalina.out log file)
Check your access to routers. Confirm, that your routers.xml file is valid, community name is correctly spelled and there is no firewall that blocks your access to routers.

Network Discovery Application starts and it completes after a couple of minutes without any results (or incomplete results).
Check your log file, if there is a WARN message: [DiscoveryManager]: "Discovery process timed out", then you should increase timeout value in router configuration file (element config/global/timeout). If there is no such message, then probably you have problems with connection to devices.

I misspelled a password couple of times and now I cannot log in (the message "Authentication failed: the account is locked" is displayed). What should I do to log in to cMA before lock expires?
You have to edit manually some values in the cNIS database. In the table user_data set attribute "login_failed_count" to 0 as value of "locked_time". Commit your changes and you will be able to login to cMA with valid user and password.
