Identify Licensing Model
- FlexNet: If your setup uses FlexNet Licensing, ensure your license server is properly configured to handle multiple users. This is the default licensing system for ARM DS-5.
- Node-Locked: This model ties a license to a specific machine. Ensure that each machine has its unique license file for access.
Review Licensing Server Configuration
Firewall Settings: The license server should be configured to allow communication through the port specified in lmgrd. Check your firewall and security settings.
Server Host Name and Port: Ensure these are correctly mentioned in the license file. A typical entry in a license file may look like:
```plaintext
SERVER this_host ANY 27000
USE_SERVER
```
License Count: Ensure that the number of available licenses matches the number of expected users.
FlexNet License File Adjustment
License File: Open the license file and ensure that the DAEMON line points to the correct path of the daemon file. It should look something like this:
```plaintext
DAEMON armlmd /path/to/armlmd
```
Debugging Logs: Enable license manager debug logs by editing the license file to include a path for the log file. Example:
```plaintext
DAEMON armlmd /path/to/armlmd log=/path/to/logfile.log
```
Check Server Health
Server Logs: Analyze lmgrd logs and armlmd logs for any errors relating to checkouts. Timeout and connectivity issues often show up here.
Server Status: Use the following command to check the server status:
```bash
lmstat -a
```
Environment Variable Configuration
ARM_HOME: Ensure this environment variable points to the correct installation directory of ARM DS-5.
LM_LICENSE_FILE: Ensure this variable is set across all user environments to point to the license server, typically in this format:
```bash
export LM_LICENSE_FILE=27000@license_server
```
Managing User Sessions
License Timeout: Set a license timeout to automatically release a license if a user has been inactive. This helps in better resource utilization.
```plaintext
TIMEOUT armlmd 1200
```
Session Management: Encourage users to close sessions when not in use, freeing licenses for others.
Script for Automated License Checkout
Use a script to check the availability of licenses and alert users if none are available. Here is a simple Bash script example:
```bash
#!/bin/bash
total_licenses=$(lmstat -c 27000@license_server | grep -c "Users of")
used_licenses=$(lmstat -c 27000@license_server | grep "Users of" | awk '{print $NF}')
if [ $used_licenses -ge $total_licenses ]; then
echo "All licenses are currently in use."
else
echo "License available. You may proceed."
fi
```
Consider Virtual Environment
- Docker or VMs: Use virtual machines or Docker containers with isolated environments. This can simplify sharing and deploying consistent environments among multiple developers.
By following these detailed steps, you can optimize your ARM DS-5 Debugger setup, ensuring smooth and effective multi-user access while minimizing licensing complaints and issues.
