Increasing the amount of memory that is available to the server
If you see "Out of memory" errors or are using the server at high capacity, increase the amount of system memory that is available to the server.

Administering
Learn how to administer settings in HCL DevOps Deploy (Deploy) elements and communication between the elements.
- Backup and recover
  You can back up and recover the contents of your HCL DevOps Deploy (Deploy) installation.
- High availability and failover
  You can configure clustered HCL DevOps Deploy (Deploy) servers, and agents for high availability. You can also configure agents and agent relays for failover.
- Setting up high-availability clusters
  To configure a high-availability cluster, you store shared files on network storage. Then, you configure multiple servers, set each server to access the same files and database, and configure a load balancer to distribute the traffic between the servers.
- Adding cold standby servers
  You can add cold standby servers to serve as a backup server or for disaster recovery. You must start the secondary server or servers when the active server fails, and network traffic is routed to the secondary servers.
- Server settings and configuration
  After you install HCL DevOps Deploy (Deploy), you can modify the server configuration and configure more options.
  - Increasing the amount of memory that is available to the server
    If you see "Out of memory" errors or are using the server at high capacity, increase the amount of system memory that is available to the server.
  - Modifying the context root of the server
    After you install the server, you can modify the context root, if your server configuration requires it.
  - Enabling maintenance mode
    Maintenance mode stops activity on the server so you can run important tasks that require the server to be idle.
  - Changing the database password
    If you change the password for your database, you must update the password on the server.
  - Changing passwords for the server KeyStore
    You can change the Java™ KeyStore password for the server.
  - Changing passwords for the encryption KeyStore
    You can change passwords for the encryption KeyStore.
  - Changing or updating the JRE of servers
    You can change the JRE of active servers by editing their configuration files.
  - Working with Notifications
    HCL DevOps Deploy (Deploy) can send email notifications whenever user-defined trigger events occur on the server.
  - Managing locks
    A lock ensures that processes do not interfere with one another. Normally, locks are released after they are no longer needed. Sometimes, a lock is not released, and its associated process is unable to complete.
  - System settings
    System settings allows you to manage global settings for components, clean up, password requirement, security, mail-server, and much more.
- Setting user preferences
  Each user can specify display options for the server, including the language for the server and how the server shows times and dates.
- Agents and agent relay configuration
  After you install an agent for HCL DevOps Deploy (Deploy), you can modify its configuration or create an agent relay to facilitate communication to remote relays.
- Licensing
  HCL DevOps Deploy (Deploy) provides a 60-day license-free evaluation period. To use all product features after the evaluation period, you must have a license.
- Setting up the wizard for new users
  HCL DevOps Deploy (Deploy) includes a wizard to help users become familiar with the procedures and steps in creating a deployment. Some configuration is required before the wizard can be used.
- Customizing the table views
  Customize a table view in the HCL DevOps Deploy (Deploy) application by hiding or showing, and reordering of the table columns.
- Managing data

Increasing the amount of memory that is available to the server

If you see "Out of memory" errors or are using the server at high capacity, increase the amount of system memory that is available to the server.

About this task

For servers that are running as a service on Windows™, see the following technote: Out of memory errors while running IBM UrbanCode Deploy.

Procedure

To increase the memory for the server on Windows™ for a non-service installation, or on Linux™ or UNIX™ systems, follow these steps:

Stop the server.
In the bin/set_env.cmd file (Windows) or bin/set_env file (Linux and UNIX), increase the memory in the JAVA_OPTS parameter.
For example, the current file might have a line that begins with the following code:
```
JAVA_OPTS="-Xmx2048m
```
To increase the memory, change the parameter that begins with the code -Xmx. For example, to increase the memory to 4 GB, use the following value: -Xmx4096m. Be sure to include the "m" at the end of the parameter.
Save the file and restart the server.
