# lspool - Maintains Redundant License Manager Pool

lspool is a redundant License Manager administration utility (command-line) for Windows and UNIX. However, if you are running on a Windows computer, you may find using the Windows-interface WlmAdmin program more convenient than using lspool.

lspool Options

The lspool options are:

Option | Description
--- | ---
-h | Displays list of lspool usage options.
-a license-server | Add the License Manager to the redundant License Manager pool. Specify the host name or IP address of the computer on which the License Manager resides. Modifies the redundant license file.
-d license-server | Delete a License Manager from the redundant License Manager pool. Specify the host name or IP address of the computer on which the License Manager resides. Modifies the redundant license file.
-l | Display the host name of the leader redundant License Manager.
-p | Display the list of License Managers in the redundant License Manager pool.
-g feature version | Display the distribution criteria for the specified feature/version. If the version is not specified, it must be replaced with empty quotation marks: " ".
-L | Disable/enable logging for an event. The events you select will be logged into the License Manager trace log file (only if error logging is enabled, see Enable Tracing to learn more about the trace log levels). A list of redundancy-related events is provided here for reference. ### lspool -L Options Events that may be logged using the -L option are:
Event | Description
--- | ---
0 | Log all events.
1 | Log License Manager up. On by default.
2 | Log election of leader License Manager.
3 | Log heart beat.
5 | Log usage information event.
7 | Log license information synchronization event.

Tips on Using lspool

- For those options that modify the redundant license file, you must have write-access to the computer on which one of the redundant License Managers resides.
- You must set the LSFORCEHOST environment variable on your computer to point to the License Manager’s computer before using lspool.
- When making changes to the redundant License Manager pool as a whole (for example, when adding or deleting License Managers to the pool), for best performance we recommend you select the leader License Manager to make the changes to.
