Administering
Learn how to administer settings in HCL Launch elements and communication between the elements.
- High availability and failover
  You can configure clustered HCL Launch 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.
- Backup and recover
  You can back up and recover the contents of your HCL Launch installation.
- Server settings and configuration
  After you install HCL Launch, 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 Launch 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.
  - Server settings
    These tables list the settings for several system-wide settings for the server.
- 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 Launch, you can modify its configuration or create an agent relay to facilitate communication to remote relays.
- License management
  HCL Launch 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 Launch 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 Launch application by hiding or showing, and reordering of the table columns.
- Managing data

Changing passwords for the encryption KeyStore

You can change passwords for the encryption KeyStore.

About this task

The encryption.keystore password must be identical to the certificate password.

Procedure

Stop the server.
Open a command line window, and go to the app_data/conf directory.
To view the alias of the secret key, run the following command:
```
keytool -keystore encryption.keystore -list -storetype jceks -storepass changeit
```
Make a note of the alias of secret key, it is required in step 6. The keytool application is included in the Java™ developer kit and is not part of HCL Launch.
Back up the encryption.keystore file.
Change the encryption KeyStore password by using the following command:
```
keytool -storepasswd -new newPassword -keystore encryption.keystore -storetype jceks -storepass changeit
```
The default password is changeit. Replace newPassword with your password of choice. The keytool application is included in the Java™ developer kit and is not part of HCL Launch.
Change the secret key password by using the following command:
```
 keytool -keypasswd -alias XXX -keypass changeit -new newpassword -keystore encryption.keystore -storetype jceks -storepass newpassword
```
where alias is the one that you noted in step 3, and the encryption KeyStore password and the secret key password must be the same.
In a text editor, open the server-install\conf\server\secured-installed.properties file. Specify the new encryption.keystore password in the following line of code:
```
 encryption.keystore.password=newPassword
```
Note: The password that you specify here must be the same as the password for the encryption KeyStore password that you specified in step 5 and the secret key password that you specified in step 6.
Start the server.

Results

Starting the server automatically encrypts the encryption.keystore password that you specified in the installed.properties file.
