Install RTP Proxy

Install the RTP proxy.

Active Node

Follow these steps to install the RTP Proxy on the primary node.

Download and extract the rtp-proxy-8.3.0.0.0.tar.gz file.
```
tar xvf rtp-proxy-8.3.0.0.0.tar.gz
```
This creates a directory called ORACLE_HOME.
Copy the contents to the ORACLE_HOME directory to your actual Oracle home directory.
```
cp -r ORACLE_HOME/* /scratch/occas/Oracle/Middleware/Oracle_Home/
```

Set the RP_CONFIG_PATH and RP_LOG_PATH variables.

export RP_CONFIG_PATH=/scratch/occas/Oracle/Middleware/Oracle_Home/config
export RP_LOG_PATH=/scratch/occas/Oracle/Middleware/Oracle_Home/log

Create the config.json file, the log4j2.xml file, and the tangosol-coherence-override.xml file.

cd $RP_CONFIG_PATH
mv config.json.sample config.json
mv log4j2.xml.sample log4j2.xml
mv tangosol-coherence-override.xml.sample tangosol-coherence-override.xml

Modify the config.json file to match the details of your environment. Pay attention to the following parameters:
- Controller.main.server – The IP address and port where you are running the RTP Proxy.
- Controller.metrics.server – The IP address and port that will serve up metrics.
- Controller.vips – The virtual IP addresses used by the RTP Proxy
- Controller.tls.enabled – Whether TLS is enabled (true) or disabled (false)
- Datapath.spec.portConfig.ports – Configure port information
- Datapath.spec.domains – Configure domains
- Datapath.spec.vipEndpoints – Set the IP address and port for the virtual IP endpoints

Add the active and standby RTP Proxy IP addresses to the tangosol-coherence-override.xml file.

<member-name system-property="coherence.member">RtpProxy1</member-name>
  <well-known-addresses>
    <address id="1"><ACTIVE_RTP_PROXY_IP></address>
    <address id="2"><STANDBY_RTP_PROXY_IP></address>
    <!-- Add as many WKA addresses as needed for your cluster -->
  </well-known-addresses>
<address system-property="coherence.localhost"><ACTIVE_RTP_PROXY_IP></address>

If your active node has the IP address of 10.1.1.1 and your standby the IP address of 10.2.2.2, your tangosol-coherence-override.xml file would contain the following:

<member-name system-property="coherence.member">RtpProxy1</member-name>
  <well-known-addresses>
    <address id="1">10.1.1.1</address>
    <address id="2">10.2.2.2</address>
    <!-- Add as many WKA addresses as needed for your cluster -->
  </well-known-addresses>
<address system-property="coherence.localhost">10.1.1.1</address>

Install the RTP proxy service.

cd $ORACLE_HOME/systemd
./install-systemd.sh

Start the service.

sudo systemctl enable --now rtp-proxy-datapath
sudo systemctl enable --now rtp-proxy-controller

See the README.md file for comprehensive details.

Standby Node

When installing the RTP proxy service on the standby node, follow the steps for the primary node with these differences:

In the config.json file, set the IP address of the following parameters to the standby IP address:
- Controller.main.server.host
- Controller.metrics.server.host

In the tangosol-coherence-override.xml file, flip the <address> nodes so that the secondary node uses the ID attribute of 1 and the primary of 2. For example, if your active node has the IP address of 10.1.1.1 and your standby the IP address of 10.2.2.2, your tangosol-coherence-override.xml file would contain the following:

<member-name system-property="coherence.member">RtpProxy1</member-name>
  <well-known-addresses>
    <address id="1">10.2.2.2</address>
    <address id="2">10.1.1.1</address>
    <!-- Add as many WKA addresses as needed for your cluster -->
  </well-known-addresses>
<address system-property="coherence.localhost">10.2.2.2</address>
