imqdbmgr

imqdbmgr(1M)						  System Administration Commands					      imqdbmgr(1M)

NAME

       imqdbmgr - manage a plugged-in JDBC-compliant Message Queue data store

SYNOPSIS

       /usr/bin/imqdbmgr subcommand argument [ [option...]]

       /usr/bin/imqdbmgr -h | -help

       /usr/bin/imqdbmgr -v | -version

DESCRIPTION

       The imqdbmgr utility creates and manages a Java DataBase Connectivity (JDBC) compliant database used for Message Queue persistent storage.

       The database can be either embedded or external. To use a JDBC-compliant database (and the imdbmgr utility), you need to first set a number
       of JDBC-related properties in the broker instance configuration file. See the Sun Java System Message Queue Administrator's Guide for addi-
       tional information.

       imqdbmgr supports four management subcommands. These subcommands, and their corresponding arguments and options follow the imqdbmgr command
       on the command line. See USAGE and OPTIONS.

       The following subcommands are supported:

       create

	   Create a Message Queue database schema.

       delete

	   Delete Message Queue database tables in the current data store.

       recreate

	   Delete Message Queue database tables and recreate Message Queue database schema in the curent data store.

       reset

	   Reset the database table lock to allow other processes to access database tables.

       The imqdbmgr subcommands support the following arguments:

       all

	   Indicates the subcommand applies to the data store, as well as the database tables.

       lck

	   Indicates the subcommand applies to the database table lock.

       oldtbl

	   Indicates the subcommand applies to an older version of the database tables.

       tbl

	   Indicates the subcommand applies to the database tables only.

OPTIONS

       The following options are supported:

       -b brokerName	       Specify the broker instance name and corresponding instance configuration properties. If this option is not  speci-
			       fied, the default broker instance is assumed.

			       Use this option with the create, delete, recreate, or reset subcommands.

       -D property=value       Set system property property to value.

			       Use this option with the create, delete, recreate, or reset subcommands.

       -h | -help	       Display usage help. Execute nothing else on the command line.

       -p password	       Specify the database password.

			       Use this option with the create, delete, recreate, or reset subcommands.

       -u userName	       Specify the database user name.

			       Use this option with the create, delete, recreate, or reset subcommands.

       -v | -version	       Display version information. Execute nothing else on the command line.

USAGE

       The following subcommands and associated arguments are supported:

       create all

	   Create a new embedded data store and Message Queue database schema for a specified or default broker instance.

       create tbl [-u userName] [-p password]

	   Create Message Queue database schema in an existing data store for a specified or default broker instance.

       delete tbl [-u userName] [-p password]

	   Delete Message Queue database tables in the current data store for a specified or default broker instance.

       delete oldtbl [-u userName] [-p password]

	   Delete  the	earlier version of Message Queue database tables. Used after the data store has been automatically migrated to the current
	   version of Message Queue.

       recreate tbl [-u userName] [-p password]

	   Delete Message Queue database tables and recreate Message Queue database schema in the current data store for a  specified  or  default
	   broker instance.

       reset lck

	   Reset the database table lock to allow other processes to access database tables.

ENVIRONMENT VARIABLES
