I'm on the QA team for MEP and have installed MEP more times than I can count. From my perspective, installing MEP is easy. I'd like to make it easy for you.
The MEP bundle comes with the open-source Application Server (Glassfish 9.1 UR2) and an ant-based installer that supports Solaris, Linux, or Windows. Ant isn't even required on your system, the ant included with GF is used.
The installer is currently CLI based (GUI installer coming in December) but it is simple and does almost everything for you. It installs GF first, then the installer deletes the default appserver domain and replaces it with a new "mep" domain with all the MEP software in it. You just have to respond to the prompts and be a little patient, while all the deployment and configuration processing is being done.
To begin, get the bundle for your platform from the download site. The Solaris bundle is biggest because it contains the binaries for both Solaris Sparc and Solaris x86. Unzip the bundle, go into the top-level directory, and you'll see the three platform install scripts: install-solaris.sh, install-linux.sh, and install-windows.bat. Basically, you execute the appropriate script and answer the prompts.
Before doing the install, make sure your system has:
- At least 1GB of disk space
- JDK 6 installed and added to your (root) path
- JAVA_HOME environment variable set
- Either MySQL or Oracle installed for use by MEP as the Sync database
For your first MEP installation, I recommend MySQL. With MySQL, the MEP installer is able to create the users and databases required by MEP; with Oracle, you have to do that work yourself. Also, Oracle uses so much system resources it is usually installed on a different system, whereas, MySQL is fine on the same system with MEP.
You can install MEP on a single system (single tier) or across two systems (two tiers). The install script asks you whether you want to do a single tier, tier1, or tier2 install. If you choose to do a two-tier install, you have to do the install twice on different systems, selecting "tier1" on the first system and "tier2" on the second system. For your first MEP installation, I suggest a single-tier.
Initially, the MEP install script does a "-console" (text based) install of GF. Just accept the license, specify the installation directory, and make sure you point to JDK 6 and not 5 (GF can be installed with JDK 5, but MEP 1.0 requires JDK 6).
Here's some tips on installing GF. The password for GF is for the GF Admin Console, not the MEP Admin Console, whose password is "syncpass". Accept the default ports 8080, 8181, and 4848. If you have good reason and specify different ports, make note of them for later reference. If you see other port numbers, it means the default ports are in use. That usually means another app server is running. If that is not intended, you should stop it, so the default easy to remember ports are freed up. When asked if you want to upgrade a previously installed version of the appserver, say NO. The reason GF is bundled with MEP is to provide you with a known quantity on which MEP has been thoroughly tested.
At the end of the GF install, it asks you to press Return to exit the installation program. It means the GF installation. Right after you press Return, the real MEP install begins. Pay attention to the message about the MEP install type. If you thought you were doing a single tier install and it says you are doing a "tier1" or "tier2" install, Ctrl-C out. On windows, the installer has a bad short-term memory and asks you where it installed GF; on Solaris and Linux, you aren't bothered.
Once you get into the MEP phase, try not to make a mistake, you can't back up, you could continue to the end and attempt to correct the problem after, but you'd have to know what you are doing. A better solution is to break out of the install, stop GF (asadmin stop-domain), delete the MEP domain (asadmin delete-domain mepdomain), and then rerun the MEP portion of the install by executing the command
gfdir/lib/ant/bin/ant -DAS_HOME=gfdir -emacs install
The last argument "install" is for a single tier install; you'd substitute "tier1" or "tier2" accordingly.
After confirming the install type, you get another license to accept: this one is for MEP itself. Accept it. When asked, agree to delete the default domain "domain1". It's only a loose end, left because the GF and MEP installs aren't totally integrated.
A most important step is providing your database information. For your first MEP install with MySQL, accept the defaults for host, port 3306, and driver. Then enter the userid and password, you use with the "mysql" command.
The final input is for the GF domain used by MEP. Accept the domain name passed through, but be careful about the ports. The defaults shown are the standard ports: 8080, 8181, and 4848. If you did not use the default ports when installing GF, you will need to specify the port numbers you used.
Now you sit back, while the MEP software is installed and deployed on GF. You'll see GF stopped and started a number of times. At the very end, the install script does a quick test to see if the MEP splash page (i.e., http://localhost:8080/sync) is accessible. You should take it one step further before declaring victory. Browse to the MEP Admin Console (i.e., http://localhost:8080/sync/admin), login with username "admin" and password "syncpass", and REGISTER THE PRODUCT. Thanks!
I'll follow up with blogs on the two-tier install and post-install configuration required to access Siebel.
