HP OpenVMS License Management Utility Manual
2.3.1 Licenses That can be CombinedWhen a system loads a license, LMF scans the License Database for all combinable licenses and makes a pool of license units available for use. Licenses are combinable if they have matching data in each of the following data fields:
VAX Availability, ALPHA Availability, VAX_ALPHA Availability, User, Activity, and Personal Use licenses are different types of licenses. Therefore, they do not combine. LMF matches any two empty data fields and, in the Availability and Activity fields, also matches the entry CONSTANT=0 with an empty data field. Licenses with the NO_SHARE option can combine, but they must have matching include lists that assign each license to the same node. This is the only time either an include list or an exclude list has an effect on license combination. By default, LMF does not automatically combine otherwise combinable licenses if any one of the following attributes do not match:
If two or more licenses are combinable except for the above attributes, you can force LMF to combine them with the following command:
2.3.2 Include, Exclude, and Reservation ListsIf you register a combinable license without an include or exclude list, any system can load the license with access to the entire pool of combined license units, with the following results:
By default, when combining Activity Licenses, LMF combines those without reservation lists into one license without a reservation list, and those with reservations lists into one license with a reservartion list that combines the separate reservation lists. By default, when combining User Licenses, LMF combines those without reservation lists into one User License without a reservation list, and those with reservations lists into one User License with a reservation list that combines the separate reservation lists.
By default, when combining Personal Use Licenses, LMF combines any
reservation lists associated with each license into one large
reservation list that applies to all the combined licenses.
With the forced combination of multiple licenses, LMF sets the termination date, release date, and version number of the combined license to the earliest dates and version numbers that apply to the individual licenses being combined. The following table shows the combined license that results from the forced combination of two licenses:

The example lists each OE and its contents in a hierarchical fashion so that the products contained in each OE are identified. The display also shows the number of units loaded.
To see the contents of a single OE, for example HA-OE, use the following command:
$ SHOW LICENSE/OE=HAOE/FULL --------- Operating Environment ---------- ------ Units ------ Name Description Type Level Loaded Total HAOE High Availability H 5 4 4 GWLM RTR-SVR VMSCLUSTER VMSCLUSTER-CLIENT AVAIL-MAN RMSJNL VOLSHAD DECRAM OMS OPENVMS-I64 OPENVMS-USER DVNETEND DW-MOTIF UCX TDC X500-ADMIN-FACILITY X500-DIRECTORY-SERVER CIFS |
This example shows all products within the HA-OE without distinguishing between operating environment hierarchies. All products contained in HA-OE and BOE are listed together.
You can upgrade or downgrade your OE without a reboot using LMF. For
example, you may want to change the number of processor cores on a
system, change the OE available on a particular node, or move a license
to another node. Any of these actions may require upgrading or
downgrading your OE. This flexibility allows you to make maximum use of
the products for which you are licensed. To upgrade to a higher OE tier
or to add license units, register and load the new license into the
database using the LICENSE REGISTER and LICENSE LOAD commands. To
downgrade, use the LICENSE UNLOAD command.
3.2 License Types
On OpenVMS Integrity server systems, there are two license types:
The following sections describe these licenses.
3.2.1 Per Core Licenses
An Integrity-specific license type, per core license (PCL), implements the licensing model on OpenVMS Integrity server systems. The PCL model licenses a product based on the number of active processor cores on the system, not the static rating scheme as on Alpha and VAX systems. Each active processor core requires one PCL unit. If you increase or decrease the number of active processor cores on a system, the requirement for PCL licenses changes.
A PCL license is required to run operating environments, OE products purchased separately (like clustering), and many standalone products on OpenVMS Integrity server systems.
PCL licenses offer flexibility as you can purchase licenses in the exact number you need and you can move the licenses to other processors. If you upgrade or reconfigure your system with additional processor cores, you purchase additional PCL licenses.
LMF constantly checks the number of PCL licenses against the number of active processor cores and enforces a soft compliance model described in Section 3.3.2. Any changes to the system are noted and checked for compliance.
If older PAKs are installed, "PPL" may still be displayed; however, the licenses will be managed as if they are the new PCL type. |
HP Integrity server blades (BL860c i2, BL870c i2, and BL890c i2) are
licensed on a per-socket basis for operating environments and layered
products. However, LMF manages the per socket licenses (PSL) identical
to PCL. The quantity of LMF units on a per socket license is equal to
the maximum number of cores available on the licensed socket. Hence,
the per socket licenses are shipped with the PCL option in the
license option field. For example, purchase of a two
socket license for quad core processors results in a quantity of eight
PCL units on the issued license.
3.2.2 Activity Licenses
For layered products such as compilers, activity licenses like those on Alpha and VAX systems are used. The units for these products are expressed in multiples of 1, rather than the 100s as on Alpha and VAX. A sample PAK for C might look like the following:
ISSUER: HP
AUTHORIZATION NUMBER: USA126087
PRODUCT NAME: C
PRODUCER: HP
NUMBER OF UNITS: 3
VERSION:
PRODUCT RELEASE DATE:
KEY TERMINATION DATE: 31-DEC-2004
AVAILABILITY TABLE CODE:
ACTIVITY TABLE CODE: CONSTANT=1
KEY OPTIONS: MOD_UNITS
PRODUCT TOKEN:
HARDWARE I.D.:
CHECKSUM: 1-BGON-IAMA-LEEH-EPEL
|
In this example, up to 3 users are licensed to use the C compiler concurrently. If a fourth user attempts to use the C compiler, that user receives the following message:
-LICENSE-F-EXCEEDED, attempted usage exceeds active license limits |
LMF will not allow the fourth user access to the C compiler. This behavior is identical to that on OpenVMS Alpha and VAX systems.
3.3 Compliance Reporting
On OpenVMS Integrity server systems, LMF checks for two types of
compliance:
The following sections describe each.
3.3.1 Hardware Compliance
To run an operating environment on an Integrity server system, you must have a license appropriate for your system rating based on sockets. A socket is a recepticle into which a processor module can be installed. Each processor module can contain one or more processor cores. Your PAK for an Integrity server system may have an entry in the HARDWARE_ID field (expressed as SOCKETS=n). For example, if your PAK has the entry SOCKETS=4 in the HARDWARE_ID field, you can load that license on a 1, 2, 3 or 4-socket system. If you try to load a license for a 2-socket system on a 4-socket system, the license will not load. In this case, LMF is enforcing a hard compliance check.
You can check the number of sockets on a system by using the following command:
$ SHOW LICENSE/CHARGE_TABLE OpenVMS I64/LMF Charge Information for node ADI26B This is an HP rx2600 (900MHz/1.5MB), with 2 cores active Type: PPL, Units Required: 2 (I64 Per Processor) Type: PCL, Units Required: 2 (I64 Per Core) |
This example shows that node ADI26B has 2 sockets. Also, note that the example displays both the PPL and PCL types, because of the number of licenses sold.
You can buy a license for an unlimited number of sockets. In that case, there is no keyword specified in the HARDWARE_ID field.
To ensure hardware compliance, add an include or excluse list to your
licenses bu using the /INCLUDE or /EXCLUDE parameter to the
/HARDWARE_ID=SOCKET tag. For example, if you are using a common license
database in a cluster with one HP Integrity rx4640 server (4 sockets),
two HP Integrity rx2620 servers (2 sockets), and one HP Integrity
rx8620 server (16 sockets), verify that the units in the 16-socket
license are used only on the rx8620. For a description of adding an
include or exclude list to a license, see Section 5.6 or the
LICENSE_MODIFY command in Appendix A.
3.3.2 Soft Compliance
In addition to having a license appropriate for your system hardware rating, you must also have a per core license (PCL) for each active processor core. The PCL units for Integrity server systems are in units of 1 per processor core.
To assist you in maintaining the terms and conditions of your licensing agreement, HP provides a reporting mechanism that flags noncompliance for per core licenses. For example, if you load a license with only 2 units a system with 4 active processor cores, the license will load but a message indicating that the system is out of compliance is logged to the OPCOM facility and a mail message is sent to the SYSTEM account. You can bring this system back into compliance in two ways: load a license with 2 additional units or deactivate 2 of the 4 processor cores.
This soft compliance mechanism gives you flexibility to alter your system configuration temporarily and reminds you that you need additional per processor licenses to run in a compliant mode. LMF checks for compliance periodically and continues to log messages to the OPCOM facility and send mail to the SYSTEM account at predetermined intervals until sufficient PCL units are loaded on to the system to bring it into compliance.
Vendors who utilize LMF to manage their product licensing may choose to
use a hard compliance model. If a vendor wants to enforce hard
compliance, they can generate a PAK with the keyword HARD_COMPLIANCE in
the OPTIONS field. Under a hard compliance policy, the license will not
load and a user cannot run the application if they do not have a
sufficient number of PCL units for each active processor core.
3.3.3 Sample License Checks
The following examples show how LMF combines checking the hardware rating and the PCL licensing requirements for OpenVMS Integrity server systems.
An rx2600 is a 2-socket system and each socket can accept only a single-processor core module. Hence, the maximum number of processors on an rx2600 is 2. A PAK for for base operation environment on this system might look like the following:
ISSUER: HP
AUTHORIZATION NUMBER: USA126087
PRODUCT NAME: OPENVMS-I64-BOE
PRODUCER: HP
NUMBER OF UNITS: 1
VERSION:
PRODUCT RELEASE DATE:
KEY TERMINATION DATE: 31-DEC-2012
AVAILABILITY TABLE CODE:
ACTIVITY TABLE CODE:
KEY OPTIONS:
PRODUCT TOKEN:
HARDWARE I.D.: SOCKETS=2
CHECKSUM: 2-NFCA-BAPO-FEJF-BDLL
|
The example shows the maximum number of sockets for this system as 2, as specified by the SOCKETS=2 keyword to the HARDWARE_ID field. This license could be loaded on any system with 1 or 2 sockets. The number of processor cores authorized to run the Base Operating Environment (BOE) by this license is 1, as specified in the NUMBER OF UNITS field. If you wanted to add another processor, you would need to purchase an additional PCL license with 1 unit.
An rx4640 system is a 4-socket system and each socket can accept either a single-processor core or a dual-processor-core module. This system may have up to 8 processor cores, depending on how it is configured. A PAK for the base operating environment on this system might look like the following:
ISSUER: HP
AUTHORIZATION NUMBER: USA126088
PRODUCT NAME: OPENVMS-I64-BOE
PRODUCER: HP
NUMBER OF UNITS: 2
VERSION:
PRODUCT RELEASE DATE:
KEY TERMINATION DATE: 31-DEC-2012
AVAILABILITY TABLE CODE:
ACTIVITY TABLE CODE:
KEY OPTIONS:
PRODUCT TOKEN:
HARDWARE I.D.: SOCKETS=4
CHECKSUM: 2-FODI-MDHC-PAIF-CEEG
|
The example shows the maximum number of sockets for this system as 4, as specified by the SOCKETS=4 keyword in the HARDWARE_ID field. This license could be loaded on any system with 1 to 4 sockets. The number of processor cores authorized to run the base operating environment by this license is 2, as specified in the NUMBER OF UNITS field. If you wanted to add more processor cores, you would need to purchase additional PCL units.
