Installation logs folder: Cognos_BI_install_path/instlog
  • HCL ® AIX® or Linux™: /opt/IBM/CognosBI/instlog

The installation wizard creates two log files: the transfer log file and the transfer summary-error log file. The log file names include the product name, version, build number, and timestamp.
  • The transfer log file records the activities that the installation wizard performed while transferring files; its file name begins with "tl" as in this example:

    tl-BISRVR-10.1-6235.152-20120825_0402.txt

  • The transfer summary-error log file records the components you installed, disk space information, the selections you made in the transfer dialogs, and any errors the installation wizard encountered while transferring components. Its file name also begins with "tl" but ends with "summary_error" as in this example:

    tl-BISRVR-10.1-6235.152-20120825_0402_summary_error.txt
