Installation troubleshooting

Installation log files and return codes can provide helpful information about a completed installation or help you identify problems encountered during an installation attempt.


Tracing is not enabled by default. You can enable tracing, set the level of tracing detail that is logged, and set the location of the debug files. To do so, include the -DDEBUG_LEVEL and -DDEBUG_FILE options with the installation command.

Log files

When you install the database server, the installation application generates log files in the same directory as the installation media. You can change the default location of your log files and enable tracing during installation.
Installation and deployment log file
The installation and deployment log file, iad_act.log, is created by the installation application when you install products in the HCL OneDB™ software bundle.
  • UNIX™, Linux™: /tmp/iad_act.log
  • Windows™: \tmp\iad_act.log
Standard output and standard error log files
The stdout and stderr log files contain important information that you can use to debug installation failures.
  • UNIX, Linux: /tmp/bundle_install.stdout and /tmp/bundle_install.stderr
  • Windows: \tmp\bundle_install.stdout and \tmp\bundle_install.stderr
Client products have separate log files.
InstallAnywhere log file
The InstallAnywhere log file contains information that is generated by the InstallAnywhere framework.
  • UNIX, Linux: $ONEDB_HOME/IBM_Informix_version_Install_date.log
  • Windows: %ONEDB_HOME%\IBM_Informix_version_Install_date.log

If the installation application fails, the InstallAnywhere log files are placed in the following directories:

  • UNIX, Linux: home directory
  • Windows: Desktop

InstallAnywhere return code (UNIX, Linux)

You can check the InstallAnywhere return code, also known as the exit code, after running the installation application to learn more about the installation status and possible error conditions. To retrieve the return code, run this command after the installation application finishes:
echo $?
For information about the InstallAnywhere return code, see the documentation at the Flexera Software web site:
