In the event that an upgrade fails, you can rollback to the previous version of the service. First, the system database should be restored with the last snapshot of the system database. Next, the keystore location should be restored with the backup of the keystore location (see Backing up a Hybrid Data Pipeline load balancer deployment for more information). Then, test the service to ensure that it is behaving as expected.

To further investigate the failure, review the installation log files. The installer generates a number of log files during the installation process. The location of these files depends on the success of the upgrade.

  • If the installer successfully creates the product installation directory, the installer generates the following log files.
    • <install_dir>/_ProgressHDPServer_installation/Logs/Progress_DataDirect_Hybrid_Data_Pipeline_Server_Install_<timestamp>.log
    • <install_dir>/ddcloud/deploy.log
    • <install_dir>/ddcloud/final.log
    • <install_dir>/ddcloud/error.log
  • If the installation or upgrade fails such that the installer does not create the installation directory, the installer writes a file named Progress__DataDirect_Hybrid_Data_Pipeline_Server_InstallFailed.txt to the machine’s default temporary directory.
  • When a silent installation or upgrade fails, the installer writes a file named SilentInstallerError.log to the user's home directory.
  • When hostname and port validation are skipped by specifying validation settings in the silent installation response file, the installer generates the file SilentInstallInfo.log in the user's home directory.
