b. Setting the work directory of DCI Bridge where all the temporary les of

DCI Bridge are stored. Its default value is the CATALINA_HOME of the
web container where the DCI Bridge as a web application can be found (in
Settings menu).
c. Providing the opportunity to give an external URL of the DCI Bridge for
middleware plugins to speed up the status sending process. This is partic-
ularly useful in the case of gLite resources, where it often happens that the
job is finished but it takes a long time to get the status and result via the gLite

middleware. In this case a special job wrapper script can immediately send
back the status and result

files via the provided external URL of the DCI

finished on the gLite resource.
d. Debugging and error handling. When the Debug mode is set to Enabled , then
the temporary job directory will not be deleted after job execution, and hence
the DCI Bridge administrator can search for a given error. Since this solution
signi

Bridge when the job is

cantly loads the local storage it is not recommended to be enabled in
production systems (in the Settings menu).
e. Access a log

file where the main user activities can be traced by the DCI
Bridge administrator (in the Log entries menu).
