#!/usr/bin/env perl # IBM(c) 2007 EPL license http://www.eclipse.org/legal/epl-v10.html # #----------------------------------------------------------------------------- =head1 db2sqlsetup This script is called after the installation of DB2 on xCAT. It will automate the setup of the DB2 to run xCAT on the IBM DB2 database on AIX and Linux. On AIX ( AIX61J - AIX61 TL5(AIX 6.1.5.0)) or later and Linux. As an option it will also setup the ODBC for C/C++ applications to be able to use the database. It will setup an xcatdb database ,a db2instance id, name xcatdb ( same as database), and instance password to be used in the /etc/xcat/cfgloc file to access the database. It will interact for the password to assign to the xcatdb for the Unix id and DB2 instance id, unless the XCATDB2PW env var is set to the password for the instance id. For Client setup, it will interact for the hostname or ip address of the DB2 Server as known by the Service Node, unless the XCATDB2SERVER environement variable is set. See man db2setup for more information The script will assume the default install paths of /opt/IBM/db2 for AIX and /opt/ibm/db2 for Linux, unless overridden with the XCATDB2INSPATH environment variable. The script will assume /var/lib/db2 for the xcat db2 database directory unless the DATABASELOC environment variable is set or the site.databaseloc attribute is set. The environment variable should match the databaseloc attribute in the site table, but the DATABASELOC environment variable will take precedence. DATABASELOC points to the directory that contains the db2 database directory, so if DATABASELOC=/db2database then the actual location for the db2 database is /db2database/db2. =cut BEGIN { $::XCATROOT = $ENV{'XCATROOT'} ? $ENV{'XCATROOT'} : '/opt/xcat'; $::XCATDIR = $ENV{'XCATDIR'} ? $ENV{'XCATDIR'} : '/etc/xcat'; } # if AIX - make sure we include perl 5.8.2 in INC path. # Needed to find perl dependencies shipped in deps tarball. # TODO: Remove during FVT should not need because DBD is compiled with # 5.8.8 and we require 61J or later which runs with 5.8.8 Perl. if ($^O =~ /^aix/i) { unshift(@INC, qw(/usr/opt/perl5/lib/5.8.2/aix-thread-multi /usr/opt/perl5/lib/5.8.2 /usr/opt/perl5/lib/site_perl/5.8.2/aix-thread-multi /usr/opt/perl5/lib/site_perl/5.8.2)); } use lib "$::XCATROOT/lib/perl"; use DBI; use xCAT::Utils; use xCAT::NetworkUtils; use Getopt::Long; use xCAT::MsgUtils; use xCAT::Table; use Expect; use Socket; use strict; #----------------------------------------------------------------------------- # Main $::progname = "db2sqlsetup"; my $args = join ' ', @ARGV; $::command = "$0 $args"; Getopt::Long::Configure("bundling"); $Getopt::Long::ignorecase = 0; # parse the options if ( !GetOptions( 'i|init' => \$::INIT, 'S|Server' => \$::SERVER, 'C|Client' => \$::CLIENT, 'N|nostart' => \$::NOSTART, 'o|odbc' => \$::SETUPODBC, 'h|help' => \$::HELP, 'v|version' => \$::VERSION, 'V|verbose' => \$::VERBOSE, 'p|passwd' => \$::PASSWD, 'r|rm' => \$::RM, ) ) { &usage; exit(1); } # display the usage if -h or --help is specified if ($::HELP) { &usage; exit(0); } # display the version statement if -v or --version is specified if ($::VERSION) { my $version = xCAT::Utils->Version(); xCAT::MsgUtils->message("I", $version); exit 0; } # # Get OS # if (xCAT::Utils->isAIX()) { $::osname = 'AIX'; } else { $::osname = 'Linux'; # determine whether redhat or sles $::linuxos = xCAT::Utils->osver(); } # overide the default install path with environment variable if ($ENV{'XCATDB2INSPATH'}) # input where DB2 is installed { $::installdb2dir = $ENV{'XCATDB2INSPATH'}; } else { if ($::osname eq 'AIX') { $::installdb2dir = "/opt/IBM/db2/V9.7"; # default } else { # linux $::installdb2dir = "/opt/ibm/db2/V9.7"; # default } } if ($::RM) { #&remove; xCAT::MsgUtils->message("I", "Remove is not currently supported"); exit(0); } if ((!($::INIT)) && (!($::SETUPODBC)) && (!($::PASSWD))) { xCAT::MsgUtils->message("I", "Either -i,-o or -p flag must be chosen"); &usage; exit(1); } if (($::NOSTART) && ($::CLIENT)) { xCAT::MsgUtils->message("I", "-N is not valid with the -C option.
