#FaQ101
---+++++ How to install web-service-client on a !GridFTP server to publish gridftp data ?
Gridview web service publisher can be installed using the rpms provided by the gridview team. 
The link for downloading the rpms is as follows:

            http://gridview.cern.ch/GRIDVIEW/downloads/

There are two required rpm files : gridview-common-wsclient    and   gridview-gridftp-wsclient

Both the above files are required for the Gridview !GridFTP WS client to work.

Prerequisite for the publisher to work -- SOAP::lite perl module (ver. > 0.67) has to be there on the server.

#FaQ102
---+++++ How to configure web-service-client on a !GridFTP server ?
If the publisher is installed through the rpm then the configuration is done automatically and most of
the time default settings are OK.

      Start the following service: gridview-gridftp-wsclient

The service runs under the default user name 'daemon'. If this user does not
exist in the server, it can be changed to any other user name. For doing this:   

1. Change the user name in /etc/init.d/gridview-gridftp-wsclient

2. Chown the /opt/gridview/logs and /opt/gridview/misc to this user name.

Gridview web service publisher can be installed using the rpms provided by the gridview team. 
The link for downloading the rpms is as follows:

            http://gridview.cern.ch/GRIDVIEW/downloads/

There are two required rpm files : gridview-common-wsclient    and   gridview-fts-wsclient

Both the above files are required for the Gridview FTS WS client to work.

Prerequisite for the publisher to work -- SOAP::lite perl module (ver. > 0.67) has to be there on the server.


#FaQ210
---+++++ How to configure web-service-client on a FTS server ?
If the publisher is installed through the rpm then the configuration is done automatically and most of
the time default settings are OK.

After the installation through rpm, one needs to set the FTSID for the installtion. By default it is 'UNKNOWN'. This has to be set to the GOCDB registered hostname for the FTS instance.

To set it, change the config files (/opt/gridview/etc/gridview-ftsok-conf.pl and /opt/gridview/etc/gridview-ftscs-conf.pl). Change the value of FTSID variable in these files.

After Setting the FTSID start the following services.

gridview-ftsok-wsclient

gridview-ftscs-wsclient

The service runs under the default user name 'daemon'. If this user does not
exist in the server, it can be changed to any other user name. For doing this:   

1. Change the user name in /etc/init.d/gridview-ftsok-wsclient and /etc/init.d/gridview-ftscs-wsclient

2. Chown the /opt/gridview/logs and /opt/gridview/misc to this user name.

#FaQ211
---+++++ Files in the FTS RPM and their interdependencies

By Default, the rpms get installed in '/opt/gridview' folder. The folder will contain following files.

1. sbin/gridview-common-wsclient.pl -- It is the main perl script, containing common functions, being used by 
all of the publishers of gridview.

2. sbin/gridview-ftsok-wsclient.pl -- This perl script parses and publishes records for Successful FTS jobs.

3. sbin/gridview-ftscs-wsclient.pl -- Similar to gridview-ftsok-wsclient.pl but it is responsible for FTS jobs 
checksum logs.

4. etc/gridview-ftsok-conf.pl and etc/gridview-ftscs-conf.pl -- Configuration files that defines the parameters for running the Publisher.

Moreover, the following files get installed in /etc/init.d for controlling the publisher service.

1. gridview-ftsok-wsclient-- This file has to go to '/etc/init.d' folder. This file is for starting 
and stopping the service, responsible for publishing records for FTS successful jobs.

2. gridview-ftscs-wsclient -- This file too has to go to '/etc/init.d/' folder. This file is for 
starting and stopping the service, responsible for publishing FTS Checksum records.

The following files get installed in /etc/logrotate.d for configuring the logrotate service to 
include gridview publisher logs.

1. gridview-ftsok-wsclient -- Log Rotation Config file. For rotating log of the FTS OK publisher.

2. gridview-ftscs-wsclient -- Log Rotation Config file. For rotating log of the FTS Checksum publisher.

And, if you change something from Default configuration then follow
the following instructions:

1. If you change the location of configuration file then you need to edit the
   main perl file to include the correct config file. This is at the top of the file.

2. If you change the name or location of logfile in config file then change the
   logrotate file accordingly.

3. if you change the path of lock or statefile in config file then make sure
   that the path exists and accessible to the user.

4. If the path or name of the main perl file has been changed then necessary
changes has to be made in the init file.

5. If your service writes in some other logfile make changes in Config file.

6. A number of other parameters are there in config file which controls the
behaviour of service.
