Hi all- I have a dedicated box, and my hosting company will not install 3rd party apps. Does anyone have a good walk-through for installing JRE so I can then install Wowza? Thanks! ---

Pretty simple. Download Java JDK 6 Update 10 from here (probably the .rpm.bin is the best one): [http://java.sun.com/javase/downloads/index.jsp](http://java.sun.com/javase/downloads/index.jsp) do a chmod to make give it execute privs: ```auto chmod +x [filename].rpm.bin ``` run the installer: ```auto ./[filename].rpm.bin ``` That is it. You should be able to execute the java command to see if it the correct version: ```auto java -version ``` If not follow these instructions: [http://community.wowza.com/t/-/48](http://community.wowza.com/t/-/48) Charlie ---

Is this a virtual private server? How much memory is in the machine? You may need to set the heap size to a very low value to start the server. To do this edit the file [install-dir]/bin/setenv.sh and change the Java heap size: ```auto from: JAVA_OPTS="-Xmx768M" to: JAVA_OPTS="-Xmx256M" ``` You may need to try lower values. The problem with this setup is that you are not going to be able to handle many concurrent connections with this much memory. I am also concerned about the initial Java installation that failed. I am not confident that Java is installed properly. Charlie ---

I am not sure. What I would do is uninstall the jre/jdk, upgrade the memory, re-install. To uninstall, find the name of the install by executing the command: ```auto rpm -qa | grep jdk or rpm -qa | grep jre ``` It should return a list of all the JDK’s or JRE’s you have installed. To uninstall, execute the command: ```auto rpm -e [name-of-jdk-or-jre-returned-above] ``` For example for me it is: ```auto rpm -e jdk-1.6.0_10-fcs ``` Charlie ---

I guess I would just go with it the way it is. Charlie ---

That looks right to me. Should be ready to install Wowza. ---

ok… I rec’d this error error: %post(jre-1.6.0\_10-fcs.i586) scriptlet failed, exit status 5 after it unpacked, but when i ran java -version it showed java version “1.6.0\_10” Java™ SE Runtime Environment (build 1.6.0\_10-b33) Java HotSpot™ Client VM (build 11.0-b15, mixed mode, sharing) should I assume I’m ok at this point? 😉 ---

I uninstalled, had the host upgrade memory/processor, and reinstalled JRE pkg. Once it unpacked the jar files, it showed error: %post(jre-1.6.0\_10-fcs.i586) scriptlet failed, exit status 5 Done. Then I ran java -version, it showed java version “1.6.0\_10” Java™ SE Runtime Environment (build 1.6.0\_10-b33) Java HotSpot™ Server VM (build 11.0-b15, mixed mode) I did find this in the Java bug database, but it doesn’t tell me if the version of Java is installed correctly or not: [http://bugs.sun.com/bugdatabase/view\_bug.do?bug\_id=6490650](http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6490650) Any Suggestions? My host (Media Temple) refuses to support 3rd-party apps, and they consider Java a 3rd party application.
