Backend server minimal requirements are the same as for WCS, except for disk storage - greater is better, if the database is on the same server.
One of recommended time series DB should be installed to store stream metric values, and SQL DB should be installed to store stream history data (Postgresql is recommended). Database can be on the same server, or on separate servers.
To install backend server:
1. Download current version from this page
wget https://flashphoner.com/downloads/builds/WCS_OAM/5.2/FlashphonerWebCallServerOAM-1.XXX.tar.gz |
2. Unpack archive FlashphonerWebCallServerOAM-1.XXX.tar.gz
tar -xvzf FlashphonerWebCallServerOAM-1.XXX.tar.gz |
3. Go to folder from archive
cd FlashphonerWebCallServerOAM-1.xxx |
4. Start installation script and follow its instructions
./install.sh |
Backed server update should be done the same way.
The following settings should be removed from wcsoam-core.properties file
