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.
- 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
  - Migrating Codestation from filesystem repositories to S3 repositories
    You can migrate your Codestation artifacts from filesystem to S3 using the S3 migrator tool.
  - Relocating CodeStation
    You can move the CodeStation artifacts to a different location on the server.
  - Caching artifacts on agent relays
    Agent relays can cache downloaded artifacts. Caching artifacts in this way improves performance because agents retrieve artifacts from agent relays instead of from the server.
  - Releasing VC LOB space
    After you upgrade to HCL Launch 7.0.5 and later, you can compress the amount of large object (LOB) storage space that HCL Launch uses in the vc_persistent_record database table.
    - Releasing LOB space in Oracle databases
      You can release the large object (LOB) storage in the Oracle databases.
    - Releasing LOB space in MySQL or Maria databases
      You can release the large object (LOB) storage in the MySQL or Maria databases.
    - Releasing LOB space in Microsoft SQL Server databases
      You can release the large object (LOB) storage in the Microsoft SQL Server database.
    - Releasing LOB space in DB2 databases
      You can release the large object (LOB) storage in the DB2 database.
  - Scanning and removing orphaned Codestation blob files
    The csorphanscan tool scans for orphaned Codestation blob files and relocates them to an orphan’s directory.
  - Cleaning up targets

Releasing VC LOB space

After you upgrade to HCL Launch 7.0.5 and later, you can compress the amount of large object (LOB) storage space that HCL Launch uses in the vc_persistent_record database table.

Before you begin

Releasing the LOB storage space is optional. If you don't release the space, it is reused when new records are added. You can decide whether you want to release the LOB storage space for the following reasons:

You can reduce storage space by 75%.
Reduce the size of one of the largest tables in HCL Launch where the text data decreases by 50-75%.
- A 2-byte character to an average of 1-byte per UTF-8 character which is up to 50% reduction.
- XML might compress by 87% or more because XML data contains many repeated keywords.

You can achieve up to a 50% reduction in read time.
