| 3 Connection to an LTPDA Repository is normally carried out as part of other processes. For example, when submitting an | |
| 4 object to the repository using the <tt>submit</tt> command, the user is prompted to login to the chosen repository. | |
| 5 </p> | |
| 6 <p> | |
| 7 It is also possible to connect to a repository using a script interface. The result is a connection object which can | |
| 8 be passed to other methods (for example, <tt>submit</tt>), thus allowing the construction of more automated procedures | |
| 9 for interacting with repositories. | |
| 10 </p> | |
| 11 <p> | |
| 12 To connect to a repository using the script interface, us the command <tt>utils.jmysql.connect</tt>. It takes the following input arguments: | |
| 13 | |
| 14 <table border="1" cellpadding="2" width="30%" bgcolor="#DDDDDD"> | |
| 15 <tr valign="top"> | |
| 16 <td><tt>hostname</tt></td><td>A hostname for the repository</td> | |
| 17 </tr> | |
| 18 <tr valign="top"> | |
| 19 <td><tt>dbname</tt></td><td>A database name to connect to</td> | |
| 20 </tr> | |
| 21 <tr valign="top"> | |
| 22 <td><tt>username</tt></td><td>[optional] A username to connect with</td> | |
| 23 </tr> | |
| 24 <tr valign="top"> | |
| 25 <td><tt>username</tt></td><td>[optional] A password to connect with</td> | |
| 26 </tr> | |
| 27 </table> | |
| 28 | |
| 29 <br> If you don't supply them as input arguments, you will then be prompted for a | |
| 30 valid username and password. | |
| 31 <br> | |
| 32 The result is a <tt>mpipeline.repository.RepositoryConnection</tt> object which can be further used to interact with the repository. | |
| 33 <br> | |
| 34 To disconnect from the server, use the <tt>closeConnection</tt> method of the <tt>mpipeline.repository.RepositoryConnection</tt> class: | |
| 35 | |
| 36 <div class="fragment"><pre> | |
| 37 >> conn.closeConnection | |
| 38 </pre></div> | |
