After you install ALM, you may need to change the heap memory values. For example, you may
want to increase the heap size if there is an increase in the number of active projects in ALM, or an
increase in the number of concurrent user sessions.
**Note:**
- The maximum heap value cannot exceed your maximum memory (RAM) size.
- On a machine running on a 32-bit operating system, the heap memory size should not
exceed 1024 MB.
**To change the heap memory size:**
1) Verify that all users have logged out of ALM projects and stop the ALM Service as follows:
- **Windows.** In the system tray, right click the ALM icon and choose **Stop Application
Lifecycle Management**.
- **Linux/Solaris.** Navigate to the **/var/opt/HP/ALM/wrapper** directory, and run the following
command: **HPALM stop**.
2) In the **ALM deployment path**, open the **wrapper.conf** file.
3) Change the **wrapper.java.maxmemory** value as necessary.
4) Restart the ALM Service as follows:
- **Windows**. In the system tray, right click the ALM icon and choose **Start Application
Lifecycle Management**.
- **Linux/Solaris**. Navigate to the **/var/opt/HP/ALM/wrapper** directory, and run the following
command: **HPALM start**.
