  1. RFT System Admin William (Bill) Allcock Argonne National Laboratory

  2. RFT Admin is mostly DB related • RFT uses the postgres database to store the state of the transfers. • Other databases may or may not work right out of the box • Oracle has a problem since it considers SIZE to be a reserved word • We intend to make our SQL as generic as possible for the future • We are not going to cover installing postgres since that varies from system to system.

  3. Use TCP • By default, postgres expects UDP connections, so we need to configure it to accept TCP. • You do this by adding “-i” on the postmaster (postgres daemon) command in the startup script. • /etc/init.d/postgresql or /var/lib/postgresql depending on your install. • they call it the postmaster, but the exe name is pg_ctl, go figure. • looks like this on Suse 9.1 personal: • pg_ctl start -s -w -p $H -l $LOGFILE -D $DATADIR -o "-i"

  4. Set the security • edit /var/lib/pgsql/data/pg_hba.conf • append the following at the end of the file: • host rftDatabase "user name "ip address" 255.255.255.255 trust • name is the name you will tell RFT to use in the jndi file • “ip address” is the address where the service (container) is running • You can share a postgres installation, but if multiple containers are running, each should have a different database name. • start (or restart) postgres • /etc/init.d/postgresql [start | restart]

  5. Create a database user • This is usually the globus user • su postgres (the postgres user is created automatically during installation) • createuser globus • if you get something like this: • psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? • you either did not add “-i” or • you did not restart after the changes

  6. create and configure the tables • As user globus (su globus) • the rest of the operations are done as user globus • Create the database • createdb rftDatabase • Populate the schema • psql -d rftDatabase -f $GLOBUS_LOCATION/share/globus_wsrf_rft/rft_schema.sql

  7. Make sure RFT can find it… • edit • $GLOBUS_LOCATION/etc/globus_wsrf_rft/jndi-config.xml • Find the dbConfiguration section under ReliableFileTransferService <service> section. • verify that the connectionString and name of the database are correct (if the install is on the same machine as Globus it probably will be)

  8. and can use it • verify that the username is the same as the user that owns/created the database • update the password if you wish

  9. Last, but not least • There are two site adjustable configurations • backoff: minimum time to wait after a failure to retry • maxActiveAllowed: what is the maximum number of transfers that an RFT service can have active at one time. • currently we do not allow the site to limit the per request concurrent transfers.
