The Sentinel VoLTE provisioning module is distributed as a Rhino Element Manager (REM) plugin.
It requires REM 2.6.1 or compatible. REM can be installed with Jetty or Apache Tomcat. For Sentinel VoLTE, the Apache Tomcat method is required.
To install the Sentinel VoLTE Provisioning module you will need:
-
the REM distribution package —
rhino-element-manager-<version>.zip
; expanded to a location of your choice -
an Apache Tomcat installation — either downloaded and configured manually, or installed via a package manager; minimum supported version is
7.0.39
-
the Sentinel VoLTE REM plugin —
sentinel-volte-element-manager-<version>.em.jar
-
download for your release version from https://repo.opencloud.com/artifactory/opencloud-sentinel-volte-2.9.0/opencloud/volte/2.9.0/sentinel-volte-element-manager
-
-
(optional) the SIS REM plugin —
sis-em-<version>.em.jar
-
download for your release version from https://repo.opencloud.com/artifactory/opencloud-sentinel-volte-2.9.0/opencloud/sis-em/2.6.1/sis-em

REM restart required
After installing and configuring the plugin, you will need to restart REM, for example by restarting the Tomcat webapp it is running in: ${CATALINA_BASE}/bin/catalina.sh stop ${CATALINA_BASE}/bin/catalina.sh start |
Set up Tomcat
To set up Apache Tomcat for the Sentinel VoLTE Provisioning module:
1 |
Follow the instructions for running REM on Apache Tomcat in the REM Guide. |
---|---|
2 |
Create the cd apache-tomcat-<version> mkdir -p rem_home/plugins |
3 |
If running Apache Tomcat using Java 1.7, you will need to increase the PermGen size. Add JAVA_OPTS="-XX:PermSize=512m -XX:MaxPermSize=512m" This step should be skipped if running Apache Tomcat on Java 1.8 or higher. |
Install the REM plugin
To install the REM plugin for the Sentinel VoLTE Provisioning Module:
1 |
Copy cd apache-tomcat-<version> cp /full/path/to/sentinel-volte-element-manager-<version>.em.jar rem_home/plugins/ |
---|---|
2 |
(Optional) Copy cd apache-tomcat-<version> cp /full/path/to/sis-em-<version>.em.jar rem_home/plugins/ |
Customize plugin logging
1 |
Edit # additional lines to add to the rem.war log4j2.properties file # the XCAP server only logs when user traffic arrives # per-request logging is at debug level logger.xcapserver.name=xcapserver logger.xcapserver.level=DEBUG # the diameter stack in the XCAP Server - logs regardless of user traffic logger.xcapdiameter.name=xcapserver.diameter logger.xcapdiameter.level=INFO # transport level logging from the XCAP Server's diameter stack # set to DEBUG for interoperability diagnostics logger.xcapdiametertransport.name=xcapserver.diameter.transport logger.xcapdiametertransport.level=INFO # part of the XCAP server logging logger.remxcap.name=rem.server.sentinel.xcap logger.remxcap.level=DEBUG # a rolling audit file of Sentinel EM plugin audit logging appender.sentinelaudit.type=RollingFile appender.sentinelaudit.name=AUDIT appender.sentinelaudit.fileName=${sys:catalina.base}/logs/sentinel-audit.log appender.sentinelaudit.filePattern = ${sys:catalina.base}/logs/sentinel-audit.log.%i appender.sentinelaudit.policies.type = Policies appender.sentinelaudit.policies.size.type = SizeBasedTriggeringPolicy appender.sentinelaudit.policies.size.size=10MB appender.sentinelaudit.strategy.type = DefaultRolloverStrategy appender.sentinelaudit.strategy.max = 10 appender.sentinelaudit.layout.type=PatternLayout appender.sentinelaudit.layout.pattern="%d{yyyy-MM-dd HH:mm:ss,SSS}", "%c{1}", %m{nolookups}%n # send Sentinel EM plugin audit logging to the AUDIT appender, only logger.sentinelaudit.name=sentinel.audit logger.sentinelaudit.level=INFO logger.sentinelaudit.appenderRef.file.ref=AUDIT logger.sentinelaudit.additivity=false |

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 Sentinel VoLTE Provisioning Module.
Use https
Be aware that the Sentinel VoLTE 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.
