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.

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

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. The lock management feature helps you to identify and resolve abnormal lock conditions.

About this task

Follow these steps to view and resolve locks.

Procedure

A running process with a lock, like all active processes, is shown on the Dashboard tab with a status of Running. If a locked process takes longer to complete than expected, you can cancel the process from the Dashboard, or investigate it fully with the Settings tab.

Display the Locks pane by clicking the Locks link on the Settings tab (Settings > Locks).

The Locks pane displays the following information:

Table 1. Lock fields
Field	Description
Name	The name identifies the lock. The displayed name is a concatenation of the component or application name (depending on type) + process name + resource name.
Type	Indicates whether the process that created the lock is a component or application type. Locks can be applied only to component or application processes.
Component/Application	Displays the name of the component or application that contains the lock. Clicking an item displays (depending on the type) the Component pane, or Application pane, where you can investigate the lock.
Resource/Environment	Displays the name of the resource or environment that contains the lock. Clicking an item displays (depending on the type) the Resource pane, or Environment pane.
Process	Displays the name of the process that contains the lock. Clicking an item displays the process in the process editor.
Actions	Lists the available actions.

Resolve the lock by selecting an action:

Table 2. Lock actions
Action	Description
View Request	Displays the process log for the process that contains the lock. You can use the Actions field on the displayed pane to see the name of the process step that is causing the lock.
Release	Releases the lock, which enables the associated process to continue processing.

If the HCL Launch server and or agents go down while a locked process is running, HCL Launch automatically restores any interrupted processes along with any locks they might contain after service is restored.
