Configuring the Host

16.5 Configuring the Host

You must have root or sudo access to tfactl to add hosts to Oracle Trace File Analyzer configuration.

To add, remove, and replace SSL certificates:

To view the list of current hosts in the Oracle Trace File Analyzer configuration:
```
tfactl print hosts
```
To add a host to the Oracle Trace File Analyzer configuration for the first time:
1. If necessary, install and start Oracle Trace File Analyzer on the new host.
2. From the existing host, synchronize authentication certificates for all hosts by running:
```
tfactl syncnodes
```
  If needed, then Oracle Trace File Analyzer displays the current node list it is aware of and prompts you to update this node list.
3. Select Y, and then enter the name of the new host.
  
  Oracle Trace File Analyzer contacts Oracle Trace File Analyzer on the new host to synchronize certificates and add each other to their respective hosts lists.
To remove a host:
```
tfactl host remove host
```
To add a host and the certificates that are already synchronized:
```
tfactl host add host
```
Oracle Trace File Analyzer generates self-signed SSL certificates during installation. Replace those certificates with one of the following:
- Personal self-signed certificate
- CA-signed certificate
