Info

Some users might be used to the full MARS client to access MARS. There are some limitations if you use the Access MARS service compared to the full MARS client:

  • You can only use retrieve or list verbs. compute, read, write... are not available
  • You can only execute one action at the time
  • You can not use multi-target using the keywords, only one final single file can be transferred at the end of the execution. See how to  Organise the output in separate files
  • You can only access to the archived data (no fdb access)

...

Info
  • This is extremely useful if you wish to download big amounts of data.
  • Efficiency tips:
    • Smaller Nr of tapes (a request accesses) means better request efficiency.
    • Requests for data which is online in general go faster
    • Ideally requests should not access more than 1 tape.
  • Please read the retrieval efficiency pages
