Installer/Uninstaller

The Unwired Accelerator installer stops with errors.

The installer checks the following, and stops with errors if it encounters a problem.

• Checks for available disk space for installing Unwired Accelerator.

• Checks for sufficient permission to create the $SYBASE installation directory.

• Verifies Unwired Accelerator can connect to Adaptive Server Enterprise.

• Verifies the Adaptive Server Enterprise page-size is 8K or more.

You must fix the problem, and then restart the installer from the beginning.

The Unwired Accelerator installer reports errors [CR #445501]

Make sure you have a home directory, such as /usr/u/username, on the IBM POWER machine, otherwise Unwired Accelerator installer cannot find the location for UA 8.0 and reports errors.

Conflict with JIT compiler

The Tomcat JIT compiler may conflict with the IBM Linux POWER JIT compiler. Sybase recommends disabling the Tomcat JIT compiler:

1. Navigate to:

   $SYBASE/jdk1.5.0_05

2. Check to see whether the JIT compiler is enabled:

   java -version
   

   Information similar to the following displays:

   java version "1.5.0"
   Java(TM) 2 Runtime Environment, Standard Edition (build pxp64dev-20061002a (SR3) )
   IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Linux ppc64-64 j9vmxp6423-20061001 (JIT enabled)
   J9VM - 20060915_08260_BHdSMr
   JIT  - 20060908_1811_r8
   GC   - 20060906_AA)
   JCL  - 20061002
   

3. If you see JIT enabled, modify the Java command line in catalina.sh to include:

   -Xnojit
   

   This disables the Tomcat JIT compiler.

MobiLink cannot connect with Adaptive Server Enterprise, and reports errors

Check the MobiLink console and the $SYBASE/logs/ml.log file for error messages. Then correct the configuration, using information in “Installing MobiLink server on Windows (optional)”.

After uninstalling Unwired Accelerator, UA databases or devices remain

This could indicate that a lock is in place for the databases or devices. see the Adaptive Server Enterprise documentation for information about finding and removing the lock.
