By default, the data tier's log files and CodeStation artifacts are stored in the var subdirectory within the IBM® UrbanCode Deploy server directory. Ideally, this data is stored on robust network storage that is regularly synchronized with an off-site disaster recovery facility. In addition, the IBM UrbanCode Deploy server needs a fast network connection to storage (agents do not need access to the storage location). In UNIX environments, you can use symbolic links from the var subdirectory to network storage. On Windows systems, there are several options for redirecting logs and artifacts, including mklink (supported in Windows 7 and later).
If you want to relocate Codestation, relocate both the var directory and the \logs\store directory. The following formula shows a good rule-of-thumb for determining Codestation storage requirements: average artifact size * number of versions imported per day * average number of days before cleanup
