How to Enable Changing SVN Log Messages or History

Issue :
When i try to change the svn log message, i am getting the error below :

Repository has not been enabled to accept revision propchanges; ask the administrator to create a pre-revprop-change hook"

Solution :

1. SVN administrator need to rename file named pre-revprop-change.tmpl under [REPOPATH]/hooks into pre-revprop-change (at the same directory without the tmpl extension).

[root@svn-server ~]# mv pre-revprop-change.tmpl pre-revprop-change

2. Change the file permission :

[root@svn-server ~]# chmod a+x pre-revprop-change
