NAME

       pegasus-rc-client - shell client for replica implementations

SYNOPSIS

       pegasus-rc-client [-Dproperty=value[...]] [-V]
                         [-c fn] [-p k=v]
                         [[-f fn]|[-i|-d fn]|[cmd [args]]

DESCRIPTION

       The shell interface to replica catalog implementations is a prototype. It determines from
       various property setting which class implements the replica manager interface, and loads
       that driver at run-time. Some commands depend on the implementation.

OPTIONS

       Any option will be displayed with its long options synonym(s).

       -Dproperty=value
           The -D option allows an experienced user to override certain properties which
           influence the program execution, among them the default location of the user’s
           properties file and the PEGASUS home location. One may set several CLI properties by
           giving this option multiple times. The -D option(s) must be the first option on the
           command line. A CLI property take precedence over the properties file property of the
           same key.

       -c fn, --conf fn
           Path to the property file

       -f fn, --file fn
           The optional input file argument permits to enter non-interactive bulk mode. If this
           option is not present, replica manager specific commands should be issued on the
           command-line. The special filename hyphen (-) can be used to read from pipes.

           Default is to use an interactive interface reading from stdin.

       -i fn, --insert fn
           The optional input file argument permits insertion of entries from the Replica Catalog
           in a bulk mode, wherever supported by the underlying implementation. This is highly,
           useful when interfacing with the Globus RLS as the backend, and one wants to inserts
           millions of entries in it.

           Each line in the file denotes one mapping of the format <lfn> <pfn> [k=v [..]]

       -d fn, --delete fn
           The optional input file argument permits deletion of entries from the Replica Catalog
           in a bulk mode, wherever supported by the underlying implementation. This is highly,
           useful when interfacing with the Globus RLS as the backend, and one wants to delete
           millions of entries from it.

           Each line in the file denotes one mapping of the format: <lfn> <pfn> [k=v [..]]

       -p k=v, --pref k=v
           This option may be specified multiple times. Each specification populates instance
           preferences. Preferences control the extend of log information, or the output format
           string to use in listings.

           The keys format and level are recognized as of this writing.

           There are no defaults.

       cmd [args]
           If not in file-driven mode, a single command can be specified with its arguments.

           Default is to use interactive mode.

       -V, --version
           displays the version of Pegasus you are using.

RETURN VALUE

       Regular and planned program terminations will result in an exit code of 0. Abnormal
       termination will result in a non-zero exit code.

FILES

       $PEGASUS_HOME/etc/properties
           contains the basic properties with all configurable options.

       $HOME/.pegasusrc
           contains the basic properties with all configurable options.

       pegasus.jar
           contains all compiled Java bytecode to run the replica manager.

ENVIRONMENT VARIABLES

       PEGASUS_HOME
           is the suggested base directory of your the execution environment.

       JAVA_HOME
           should be set and point to a valid location to start the intended Java virtual machine
           as $JAVA_HOME/bin/java.

       CLASSPATH
           should be set to contain all necessary files for the execution environment. Please
           make sure that your CLASSPATH includes pointer to the replica implementation required
           jar files.

PROPERTIES

       The complete branch of properties pegasus.catalog.replica including itself are interpreted
       by the prototype. While the pegasus.catalog.replica property itself steers the backend to
       connect to, any meaning of branched keys is dependent on the backend. The same key may
       have different meanings for different backends.

       pegasus.catalog.replica
           determines the name of the implementing class to load at run-time. If the class
           resides in org.griphyn.common.catalog.replica no prefix is required. Otherwise, the
           fully qualified class name must be specified.

       pegasus.catalog.replica.url
           is used by the RLS|LRC implementations. It determines the RLI / LRC url to use.

       pegasus.catalog.replica.file
           is used by the SimpleFile implementation. It specifies the path to the file to use as
           the backend for the catalog.

       pegasus.catalog.replica.db.driver
           is used by a simple rDBMs implementation. The string is the fully-qualified class name
           of the JDBC driver used by the RDBMS implementer.

       pegasus.catalog.replica.db.url
           is the JDBC URL to use to connect to the database.

       pegasus.catalog.replica.db.user
           is used by a simple rDBMS implementation. It constitutes the database user account
           that contains the RC_LFN and RC_ATTR tables.

       pegasus.catalog.replica.db.password
           is used by a simple RDBMS implementation. It constitutes the database user account
           that contains the RC_LFN and RC_ATTR tables.

       pegasus.catalog.replica.chunk.size
           is used by the pegasus-rc-client for the bulk insert and delete operations. The value
           determines the number of lines that are read in at a time, and worked upon at
           together.

COMMANDS

       The command line tool provides a simplified shell-wrappable interface to manage a replica
       catalog backend. The commands can either be specified in a file in bulk mode, in a pipe,
       or as additional arguments to the invocation.

       Note that you must escape special characters from the shell.

       help
           displays a small resume of the commands.

       exit, quit
           should only be used in interactive mode to exit the interactive mode.

       clear
           drops all contents from the backend. Use with special care!

       insert <lfn> <pfn> [k=v [...]]
           inserts a given lfn and pfn, and an optional site string into the backend. If the site
           is not specified, a null value is inserted for the site.

       delete <lfn> <pfn> [k=v [...]]
           removes a triple of lfn, pfn and, optionally, site from the replica backend. If the
           site was not specified, all matches of the lfn pfn pairs will be removed, regardless
           of the site.

       lookup <lfn> [<lfn> [...]]
           retrieves one or more mappings for a given lfn from the replica backend.

       remove <lfn> [<lfn> [...]]
           removes all mappings for each lfn from the replica backend.

       list [lfn <pat>] [pfn <pat>] [<name> <pat>]
           obtains all matches from the replica backend. If no arguments were specified, all
           contents of the replica backend are matched. You must use the word lfn, pfn or <name>
           before specifying a pattern. The pattern is meaningful only to the implementation.
           Thus, a SQL implementation may chose to permit SQL wild-card characters. A
           memory-resident service may chose to interpret the pattern as regular expression.

       set [var [value]]
           sets an internal variable that controls the behavior of the front-end. With no
           arguments, all possible behaviors are displayed. With one argument, just the matching
           behavior is listed. With two arguments, the matching behavior is set to the value.

DATABASE SCHEMA

       The tables are set up as part of the PEGASUS database setup. The files concerned with the
       database have a suffix -rc.sql.
