Qlik Talend Administration Center: How to resolve RepoProjectRefresher - Error GC error

[wei_guo]

The following error message appears repeatedly in the logs.

2024-01-20 08:50:10 ERROR RepoProjectRefresher -
2024-01-10 16:58:47 ERROR GC - D:\Talend\7.3.1\tac\apache-tomcat\temp\_git\

 

Cause 

The main reason for the log type is that the RepoProjectRefresher faces out of memory issues. By default, TAC automatically caches/checks out the project source code into the tac\apache-tomcat\temp folder. When the source code accumulation is large, the RepoProjectRefresher module will consume a lot of memory. When maximum value is reached, a GC error will occur and a GC error log will be generated.

Note: The RepoRefresher cache functionality has been deprecated in the latest version of TAC v8.0.1

 

Resolution

Disable the Git caching mechanism for the TAC project by following these steps:

1. Update whitelist setting for TAC DB t731 using query.

   update t731.configuration set value='true' where configuration.key='git.whiteListBranches.enable';
    
   update t731.configuration set value='\"Technical labels of project\",\"Active branch name\"' where configuration.key='git.whiteListBranches.list';
    

2. Delete the previous Git whitelist cached setting file: talend\tomcat\webapps\tac\WEB-INF\classes\active_git_branches.csv
3. Restart TAC.
