The IPSMGW Element Manager module is distributed as a Rhino Element Manager (REM) plugin.

Note The IPSMGW Element Manager module should be installed if the REM instance is only used to provision Sentinel-IPSMGW. If REM will be used to provision both Sentinel-VoLTE and Sentinel-IPSMGW installations then only the Sentinel VoLTE provisioning module should be installed. The Sentinel VoLTE provisioning module is capable of provisioning both Sentinel-IPSMGW and Sentinel-VoLTE installations. See Installing the Sentinel VoLTE Provisioning Module.

It requires a standalone distribution of REM 1.5.0.4 or later. REM can be installed with Jetty or Apache Tomcat. For IPSMGW, the Apache Tomcat method is required.

You’ll need these files to install the IPSMGW Element Manager module:

  • apache-tomcat-<version>.zip

  • rhino-element-manager-<version>.zip

  • ipsmgw-element-manager-<version>.em.jar

Below are the procedures to:

Set up Tomcat

To set up Apache Tomcat for the IPSMGW Element Manager module:

1

Follow the instructions for running REM on Apache Tomcat in the REM Guide.

2

Create the rem_home/plugins directory.

cd apache-tomcat-<version>
mkdir -p rem_home/plugins

Install the REM plugin

To install the REM plugin for the IPSMGW Element Manager Module:

1

Copy ipsmgw-element-manager-<version>.em.jar into rem_home/plugins.

cd apache-tomcat-<version>
cp /full/path/to/ipsmgw-element-manager-<version>.em.jar rem_home/plugins/

Customize plugin logging

1

Unzip log4j.properties from rem.war:

cd apache-tomcat-<version>
mkdir rem-tmp
cd rem-tmp
unzip ../webapps/rem.war WEB-INF/classes/log4j.properties

2

Edit WEB-INF/classes/log4j.properties with this content:

log4j.rootLogger=INFO, FILE, CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %-5p <%t> [%c] %m%n

log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=${rem.home}/rem.log
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p <%t> [%c] %m%n

log4j.logger.rem=INFO
log4j.logger.openjpa=INFO
log4j.logger.org.apache.wink=INFO

log4j.logger.sentinel.audit=INFO, AUDIT
log4j.additivity.sentinel.audit=false

log4j.appender.AUDIT=org.apache.log4j.FileAppender
log4j.appender.AUDIT.File=${rem.home}/sentinel-audit.log
log4j.appender.AUDIT.layout=org.apache.log4j.PatternLayout
log4j.appender.AUDIT.layout.ConversionPattern="%d{yyyy-MM-dd HH:mm:ss,SSS}", "%c{1}", %m%n

3

Replace WEB-INF/classes/log4j.properties in rem.war:

zip ../webapps/rem.war WEB-INF/classes/log4j.properties

4

Remove temporary files:

cd ..
rm -rf rem-tmp

Import Rhino trust certificate

This can also be done using the REM web UI.

1

Import a Rhino Trust Certificate into REM:

"${JAVA_HOME}/bin/keytool" -importcert -file ${RHINO_HOME}/rhino-trust.cert -keystore "${TOMCAT_HOME}/rem_home/rhino-ems.ks" -storepass changeit -noprompt

Security considerations

Below are recommendations for securely running the IPSMGW Element Manager Module.

Use https

Be aware that the IPSMGW Element Manager machine API uses HTTP BASIC authentication. This passes the username and password with every request.

To prevent your credentials going over the network unencrypted, run REM over https.

Set up SSL

See the Tomcat 7 - SSL How-To docs for help setting up SSL in Apache Tomcat 7.
