# Quick Fix

## Applying Quick Fix

A quick fix is a QPPM (Quick PPM) file designed to patch small but important changes. They are applied faster than service pack releases and provide an effective way to quickly address vulnerabilities when a normal upgrade is not feasible.

## How to install the quick fix?

### If you do not use Failover Server:

1. Download the QPM file.
2. Copy the QPM file to the directory `<installed_location>/quickfixer/qppm`.
3. Restart the Central Server service.

### If you use Failover Server:

1. Stop the Central Server service on the secondary server (only stop the service, not the machine).
2. Download the QPM file.
3. Copy the QPM file to the directory `<installed_location>/quickfixer/qppm` located on the primary server.
4. Restart the primary service after applying the fix.
5. Once the primary service is running, start your secondary service.

**Points to Note:**

- On the secondary server, it is important to **stop the Central Server service but keep the machine on** before downloading the QPM file.
- While applying the quick fix on the primary server, ensure the secondary server is **on and reachable** for the changes to be replicated.
- The **service startup may take longer than usual** as the QPM file is deployed.

## How to verify if the quick fix is applied?

1. After the server fully restarts, log into the Central Server console and navigate to the **Support** tab.
2. If the fix is successfully applied, it will be displayed under the **Upgrade Details** tab.
3. If the fix installation has failed, a failure alert will be displayed.

## FAQs

**1. Why should I install QPM instead of PPM?**

**Answer:** QPM patching is quicker and easier compared to a PPM update. QPM is useful when a PPM upgrade is not feasible, and only a small but urgent change is needed. QPM does not require the UpdateManager window and only requires a server restart to apply the fix.

**2. Can I use this quick fix even if it is not applicable to my build?**

**Answer:** A quick fix is generated for a specific build. If your server is not on that build, the fix will not work. In such cases, you must upgrade to the latest build using PPM.
