List of Files You Can Safely Delete

• Bridge Log Files

  Bridge log files can be deleted at any time. Current log files may be locked by services. If you delete a log file of the current day, the Bridge will create a new one and continue logging to the new file.

  The following log files can be deleted without effecting the system:

  • all xUML service and Node.js service logs from <your bridge data directory>/<service directory>/logs
  • all Bridge access and error logs from <your bridge data directory>/servlets/logs/admin
  • all proxy logs from <your bridge data directory>/proxies/logs
• Service Backup Files
  On every service deployment, the Bridge creates a service export of the old service as a backup to folder <your Bridge data directory>/backup.
• System Files of Old Installations
  In your Bridge program folder, you may find folders containing old installations of
  • xUML Runtime, e.g. bridgeserver-2019.1
  • Apache, e.g. apache-2.2.29
  • Tomcat, e.g. tomcat-9.0.12
  • Node.js, e.g. nodejs-8.9.1
  • Java, e.g. j2re-1.8.152

  These folders can safely be deleted, if you do not have any services up and running that use them.

  You can see the versions of the installed software on the Runtime tab of your Bridge. See Managing the Runtime of the Node Instance for more information on this. Alternatively, you can look into <your Bridge program folder>/console.properties, where you can find entries for all used software versions.

Purge Files on Linux

To clean-up Bridge log files and service backup files on Linux, you can use shell script purge.sh. The script resides in <your Bridge program directory>/bin/.

Usage:

[DAYS=<a number of days>] <your bridge program directory>/bin/purge.sh [remove|dryrun]

Parameters:

Removed the following log files because they were older than 7 days: 
/opt/e2e_bridge_data/bridge_SAP_PurchaseOrder/logs/transaction_2019-03-22.log

By setting the environment variable DAYS, you can define the period of time to be considered.
