This article is for users who are installing Analyze "side-by-side" on the same box with the LAE (old version) software.
PROBLEM BACKGROUND:
During an fresh installation or an upgrade on Linux, you may say see something like the following:
Failed to generate trusted host key pair. Please check laeConfig.log under the log directory.
Ignore [i, Enter], Quit [q]
i
Failed to create trusted host: /lav00d10/lavastorm/Data3SixtyAnalyze/.profile.lavastorm:
line 6: ulimit: open files:
cannot modify limit: Operation not permitted
ERROR: The Maximum number of open files (2048) is insufficient (require at least 4096).
Please consult your System Administrator.
Error: Could not find or load main class com.lavastorm.lae.application.wrapper.

ROOT CAUSE:
The old Linux environment variables may be still pointing to LAE.
If you have LAE (our old software) installed, you'll need to ensure that your Linux environment has NO references to any LAE folders. This applies both to doing the initial install, and any time you wish to start Data3Sixty Analyze - any environment references to the old software will cause Analyze to not start properly.
Note: using both systems on the same user account may cause you difficulty with system limits such as max number of open files, or max number of tasks.
RESOLUTION:
To resolve this, you'll need to clean out the LAE environment variables and start the installer again. This ensures that there are no links to LAE.
Cleaning the variables can be done in one of three ways:
1) don't load LAE/ .profile.lavastorm for the current login session
2) manually remove all references to LAE from any environment variable
3) use the attached source clearEnv.sh script - RECOMMENDED
