During opennms installation, a solution with the error "cannot find jrrd. dll" is displayed.

When opennms is installed on Windows 2003 Server (Virtual Machine), the error jrrd. dll cannot be found. I tried to download jrrd-1.0.7.tar.gz from opennms. I found that the DLL file was not compiled by myself and felt that this problem would occur in Linux. So I gave up the Chinese Installation Guide and re-installed it according to the steps on the official website.

1. After installing PostgreSQL, you are prompted to "Create a database in your SQL _root \ data", so you can use "initdb-e UTF-8-u Postgres .. \ data ". The error message is" no permission ". Setting folder permissions can solve this problem.

2. PostgreSQL needs to be started manually and use "pg_ctl start-d" ../Data "to start the database. Then, you can use pgadmin to open the database.

3. Install opennms, And the jrrd. dll error is not prompted. (But there are still problems in the process. I don't know if it will affect it)

4. Using the "opennms. bat start" command, there are still Java errors, but you can see the content published on the Web by logging on to http: // localhost: 8980/opennms.
