Log locations for Cognos components

While troubleshooting IBM Cognos Business Intelligence components, we might need to review the logs generated by each server. We can locate the logs for each component below the component’s install directory.

Table 1 provides the log location for each server component deployed with Cognos Business Intelligence.

Log Location

Cognos BI Server

Installation logs folder: Cognos_BI_install_path/instlog

  • IBM AIX or Linux: /opt/IBM/CognosBI/instlog

  • Windows: C:\IBM\Cognos\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 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
