Troubleshooting Your Maintenance Installation
Problem:
While updating from an existing installation, the type management code reports certain exceptions pertaining to incorrect mapping attributes.
Action:
These error messages can be safely ignored.
Problem:
You cannot find the Windchill Service Pack log files in the <Windchill>/installer/logs directory.
Action:
Look for the log files in the temporary directory that your system uses. Look in %TMP% on Windows and either /var/tmp or /tmp (JVM implementation dependent) on UNIX.
Problem:
You receive an attention window with the following message:
ATTENTION: The Windchill Service Pack does not contain any
updates for the products in directory <install_dir>.
Action:
The message says that the Windchill Service Pack does not contain any content for updating any products in the selected <install_dir> directory.
Check for the selected directory in the list of directories you established when you did your planning. The selected directory should not be in the list. Run the installer again, selecting an installation directory that is on your list.
Problem:
You receive an attention window with the following message:
ATTENTION: The <install_dir> directory contains 1 base product
installations that are incomplete. In their current state,
they cannot be updated. Quit the Windchill Service Pack and
successfully install these products before doing the update. See the
WSP_PtcInstall.log log for the incomplete products.
Action:
The message says that the installation of one or more base products in the <install_dir> directory was incomplete.
Rerun the installation of the base products identified in the Windchill Service Pack log file before trying to update them using the service pack.
Problem:
The installer is incorrectly reporting an insufficient amount of disk space available, preventing installation of the product.
Action:
Turn off disk space checking by running the installer from the command line and adding the following option to the installer command.
Windows:
cd <OD_ROOT>/Windows
setup.exe -DCHECK_DISK_SPACE=OFF
Unix:
cd <CD_ROOT>
setup -DCHECK_DISK_SPACE=OFF
Problem:
Windchill update fails with the exception:
Unable to delete file E:\Windchill\Java\bin\java.exe
Action:
Close the Windchill DS control panel, if open and then recover the failed Windchill update through PSI.
