How to clear the Talend Administration Center (TAC) cache

[TalendSolutionExpert]

It can be useful to clear the Talend Administration Center cache for any number of issues that appear, either within Talend Administration Center or Talend Studio.

At a high level:

1. Stop TAC.
2. Navigate to tac-installation-folder\apache-tomcat\ and clear all contents of the temp and work folders.
3. Clear the web browser cache.
4. Restart TAC.

In the examples below, the TAC service is stopped and started manually, using the Talend-provided .sh and .bat files.

UNIX/Linux

cd /opt/Talend-6.4.1/tac
./stop_tac.sh
cd apache-tomcat
rm -rf ./temp/*
rm -rf ./work/*
cd ..
./start_tac.sh

Windows

cd C:\Talend\6.4.1\tac
.\stop_tac.bat
cd apache-tomcat
del /Q /s /F temp\*
del /Q /s /F work\*
cd ..
.\start_tac.bat
