Possible Causes of “Activate Changes” Not Working
1️⃣ Pending or Conflicting Changes
- Uncommitted changes from previous sessions
- Multiple administrators making changes at the same time
2️⃣ WebLogic Configuration Lock Issues
- Configuration changes are stuck due to an active lock on the domain.
3️⃣ Memory or Performance Issues
- The Admin Server is running low on memory, causing UI actions to be unresponsive.
4️⃣ Corrupt Configuration Files
config.xmlor other domain configuration files are corrupt or incorrectly modified.
5️⃣ Admin Console Session Timeout
- If the session expires while making changes, they may not be committed.
How to Fix the “Activate Changes” Issue
🔹 Step 1: Check for Pending Changes
- In the WebLogic Admin Console, navigate to:
Change Center > View Changes and Restarts - If there are pending changes, commit or revert them.
🔹 Step 2: Unlock Configuration Changes
- If another user is holding a lock, unlock it using:
releaseConfiguration() - Restart the Admin Console session and try again.
🔹 Step 3: Restart the Admin Server
- If the issue persists, restart the Admin Server to refresh the configuration state.
🔹 Step 4: Manually Edit and Validate config.xml
- Check for corruption by validating
config.xml:cd $DOMAIN_HOME/config xmllint --noout config.xml - If errors are found, restore a backup version.
🔹 Step 5: Increase Admin Server Memory
- If memory is an issue, increase JVM heap size in
setDomainEnv.shorsetDomainEnv.cmd:-Xms1024m -Xmx2048m - Restart the Admin Server for changes to take effect.
Best Practices to Avoid Future Issues
✔ Always Review Pending Changes Before Activating
✔ Avoid Multiple Admins Making Changes at the Same Time
✔ Take Regular Backups of config.xml Before Modifying It
✔ Monitor Admin Server Memory Usage and Performance
