Installing or upgrading Disconnected Log Collector on Ubuntu Linux

Install IBM Disconnected Log Collector on a computer or virtual machine (VM) that meets all the system requirements. You can install only one instance of Disconnected Log Collector per computer or VM.

About this task

Procedure

Go to https://www.ibm.com/support/pages/java-sdk-downloads-version-80, and download the SDK version of the Linux® on x86 systems 64-bit Archive package.
Verify that the /opt/ibm directory exists on your system by running the following command:
```
ls /opt/ibm
```
If the directory does not exist, run the following command:
```
mkdir /opt/ibm
```
Extract the Java archive by running the following command:
```
tar -zxvf ibm-java-sdk-<version>-linux-x86_64.tgz -C /opt/ibm
```
After you install Java, you must update the PATH variable to include /opt/ibm/ibm-java-x86_64-80/jre/bin. This is required later to run the update-ca-certificates.
```
echo 'export PATH=$PATH:/opt/ibm/ibm-java-x86_64-80/jre/bin' >> ~/.profile
```
```
source ~/.profile
```
Install the ca-certificates-java package by running the following commands:
```
apt update
```
```
apt install ca-certificates-java
```
Copy the dlc-service-install-deb.tgz file to your system and extract the file by running the following command:
```
tar -zxvf dlc-service-install-deb-<version>.tgz
```
Run the Disconnected Log Collector installation script:
```
./install.sh
```
To uninstall your Disconnected Log Collector instance, run the uninstallation script:
```
./uninstall.sh
```

Results

To verify a successful installation process, run the following command:

systemctl status dlc

An active (running) message indicates that the installation was successful and that Disconnected Log Collector is running.
