Perl modules are also required. You can obtain these CPAN modules (DBI and Oracle DBD) from the following Web sites: ¶   For the DBI module, see: http://search.cpan.org/search?module=DBI ¶   For the Oracle DBD module, see: http://search.cpan.org/search?module=DBD::Oracle For more information on the Oracle application, see  Oracle Application” on page 91. Installing the Perl Library The UaTk module must be installed on the endpoint where the custom application is running and be made available to the application. The standard location for this Perl module is the site-perl  directory. To check Perl installation directories, use the following command: perl -V Note the directory listings under  @INC. Examples of typical installation directories are listed below: ¶   On UNIX systems: /usr/local/lib/perl5/site_perl/5.6.0/<interp> ¶   On Windows NT systems using CYGWIN: /lib/perl5/site_perl/5.6.1/cygwin ¶   On Windows NT systems using ActivePerl: D:\Perl\site\lib For related information, see  Installing the Toolkit” on page 5 and Oracle Application” on page 91. Using the Perl Library Once installed, the UaTk module reads and interprets a data stream originating from an Application Management Toolkit server. The data stream consists of commands and data that UaTk reacts to using a Developing Your Application in Perl 55 Tivoli®  SecureWay Application Management Toolkit Guide
