Deployment for Java

The Logi Info Scheduler Service for Java runs on the Linux/UNIX or Windows operating systems. It's distributed as part of the Logi Info product and, regardless of the server type that you plan to run it on in the end, in order to access its files it must first be installed on a Windows machine, using the Windows product installer, as shown in Deployment for Windows. Naturally, during the process you select the Scheduler Service for Java feature option, not the service for .NET.

The default installation location is: C:\Program Files\LogiXML IES Dev\LogiXML Scheduler Service Java. In the rest of this topic, the installation folder you specified, the default or a custom location, will be abbreviated as <installFolder>

On a Windows Server

By default, the Scheduler Service for Java, installed on a Windows server, isn't configured to start automatically. Instead, it's started by running:

    <installFolder>\bin\Scheduler.bat.

When running the Scheduler Service for Java on Windows 7 or Windows Vista, the User Account Control (UAC) system can interfere with normal operations of the Scheduler, as the <installFolder>\Log, \RunNowTasks and \Schedules folders require Write file access permissions. There are two options to resolve this: either disable UAC on the server, or use UAC to set the privileges of these directories to allow Write access. This MSDN article provides more information about UAC should you need it.

If you wish to start the Scheduler service automatically, and you feel comfortable directly modifying system-level configurations, use the Registry editor to add a String value in

    HK_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run

Set its Value Name to LogiSchedulerJava and its Value Data to <installFolder>\bin\Scheduler.bat.

On a Linux/UNIX Server

In order to subsequently install the Scheduler Service for Java on a Linux/UNIX server, copy all of the subfolders and files from the <installFolder> on the Windows machine to the desired installation folder on your Linux/UNIX server. That folder on your Linux/UNIX server now becomes your <installFolder> for the rest of this discussion.

The Scheduler is started by running <installFolder>/bin/Scheduler.sh. Don't use a symbolic link for this, as it may lead to unstable behavior.

To start the Java scheduler automatically, add a line to /etc/rc.d/rc.local. The invocation should be similar to

    /opt/LogiSchedulerJava/Scheduler.sh &

The ampersand (&) at the end is significant: it causes the application to load as a background process.

Due to the flexible nature of the Scheduler and its interactions with Logi Info applications, you can install the Scheduler on a different server than the application web server, separate from Logi Info, if desired.
