JBoss AS 7 How to clean up tmp

Question

I noticed that in my JBoss Application Server 7 installation under standalone tmp I have 400 MB of files related to past deployments  some of them a few months old   How is it cleaned up  Should it happen automatically  Is there a tool for it  Can I just remove all those files myself

I do not have experience with version 7 of JBoss but with 5 I often had issues when redeploying apps which went away when I cleaned the work and tmp folder  I wrote a script for that which was executed everytime the server shut down  Maybe executing it before startup is better considering abnormal shutdowns  which weren t uncommon with Jboss 5

As you know JBoss is a purely filesystem based installation  To install you simply unzip a file and thats it  Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time  it creates additional folders for runtime operation  For comparison here is the structure of JBoss AS 7 before and after you start for the first time  Before  jboss-as-7      --- gt  standalone          ---- gt  lib          ---- gt  configuration          ---- gt  deployments            --- gt  domain          After  jboss-as-7              --- gt  standalone              ---- gt  lib              ---- gt  configuration              ---- gt  deployments              ---- gt  tmp              ---- gt  data              ---- gt  log                    --- gt  domain              As you can see 3 new folders are created  log  data  amp  tmp   These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that s stored in those folders  In development  its ok to delete all these 3 new folders assuming you don t have any need for the logs and data stored in  data  directory    For production  ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application  For ex  in the data folder  the appserver can save critical Tx rollback logs  So contact your JBoss Administrator if you need to delete those folders for any reason in production   Good luck
