RFT System Admin
William (Bill) Allcock

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.
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"
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]
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
create and configure the tables

As user globus (su globus)


Create the database


the rest of the operations are done as user
globus
createdb rftDatabase
Populate the schema

psql -d rftDatabase -f
$GLOBUS_LOCATION/share/globus_wsrf_rft
/rft_schema.sql
Make sure RFT can find it…

edit



$GLOBUS_LOCATION/etc/globus_wsrf_rft/jndiconfig.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)
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
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.
