 Press RETURN for more information 
 
    The license checksum is a 17-character verification string created by 
    the PAK issuer for each PAK.  The checksum string is presented in 
    the format n-cccc-cccc-cccc-cccc, where n is an integer and c is a 
    character from A through P.  A PAK presents the checksum string with 
    hyphen (-) characters for readability.  Because the LMF does not count 
    them for authorization, you can leave them out.  Otherwise, you must 
    enter the checksum string exactly as specified on your PAK. 
 
    If a default value is displayed and you wish to use it just press 
    the RETURN key.   To cancel the use of default data without 
    entering new data, enter the backslash (\) character. The 
    license checksum is a required field for the REGISTER and AMEND 
    options. 
 
                      Checksum []: 

You can use VMSLICENSE.COM in batch mode as well as interactively. Instead of entering the PAK data interactively from your terminal or workstation, you can create a VMSLICENSE data file with an editor and enter data obtained from your product PAKs (Example 5-2 shows sample PAK data). You can then invoke VMSLICENSE.COM, specifying the name of the new VMSLICENSE data file as a parameter on the same command line. The procedure displays the license data and performs the requested operation or operations using data only from the VMSLICENSE data file.

You can create a file that registers multiple licenses. VMSLICENSE.COM exits only when it reaches the end of the VMSLICENSE data file.

5.4.4.2 Invoking VMSLICENSE.COM with a VMSLICENSE Data File

To pass a VMSLICENSE data file to VMSLICENSE.COM, use the following format:

$ @VMSLICENSE [license-option] vmslicense-data-file [license-database] 

When you invoke VMSLICENSE with a data file, you must specify REGISTER as the license-option. You cannot use data files with any of the other options that are available when using VMSLICENSE interactively.

You can specify a License Database on the command line or in the data file. Any License Database you specify in the data file overrides a License Database you specify on the command line.

For example, you can pass the data in the sample VMSLICENSE data file, shown in Example 5-2, with the following command line:

$ @VMSLICENSE REGISTER NODES_A_AND_B_VMS_LICENSE.DAT

! 
! License for COBOL on NODEA 
!         
DATABASE_FILE   = SYS$COMMON:[SYSEXE]LMF$LICENSE.LDB 
ISSUER          = DEC 
PRODUCT_NAME    = COBOL 
AUTHORIZATION   = USA00326 
UNITS           = 1200 
VERSION         = 7.3 
AVAILABILITY    = A 
OPTIONS         = MOD_UNITS,NO_SHARE 
CHECKSUM        = 1-DELM-EAHF-ONIH-MBAH 
INCLUDE_NODE    = NODEA           
! 
<NEXT> 
! 
! License for COBOL on NODEB 
! 
AUTHORIZATION   = USA00327 
UNITS           = 800 
CHECKSUM        = 1-PATC-IDOH-EPOF-MOHG 
INCLUDE_NODE    = NODEB 
! 

When you create a VMSLICENSE data file to be processed by VMSLICENSE.COM, you must follow these rules (refer to Example 5-2):

• Specify all PAK data as parameters in the form of DCL assignment statements. Use the following format:

  parameter = parameter-value ! comment

  
  Table 5-1 lists the parameters allowed in the VMSLICENSE data file. You must use the exact parameter names, or VMSLICENSE ignores the line in the VMSLICENSE data file and returns an error message.

• Separate the end of one license registration from the beginning of another with the following special license data separator:

  <NEXT>

• Precede each comment with an exclamation point; VMSLICENSE ignores everything to the right of an exclamation point when processing the line.
• Separate words in the VMSLICENSE data file with any number of spaces or tabs.
• List parameters in any order in the VMSLICENSE data file.

If you do not specify a value for a parameter in a VMSLICENSE data file, VMSLICENSE substitutes default values. The current default values are ISSUER=DEC and PRODUCER=DEC on OpenVMS Alpha and VAX systems and HP on OpenVMS Integrity server systems. All other license parameters have null values until you specify a value.

After you specify a license parameter in the VMSLICENSE data file, the parameter becomes the new default value until the next occurrence of the parameter sets a new default value. To set or reset the value of a parameter to null, use a line of the following form:

For example, if the most recent PAK data set the INCLUDE_NODE parameter to a specific node, reset the parameter to null for the current and subsequent PAKs by entering the following:

INCLUDE_NODE = "" 

Example 5-2 shows how using default data can eliminate typing for the second PAK listed in the VMSLICENSE data file.

5.4.5 Using the LICENSE REGISTER Command

You can directly register (and load) a license with LICENSE commands. For example:

$ LICENSE REGISTER CRYPTICALMENT /ISSUER=DEC -
_$ /AUTHORIZATION=USA126087 /PRODUCER=DEC /UNITS=460 -
_$ /VERSION=7.3 /TERMINATION_DATE=31-DEC-2001 /AVAILABILITY=E -
_$ /OPTIONS=(MOD_UNITS) /CHECKSUM=1-BGON-IAMA-GNOL-AIKO
$ LICENSE LOAD CRYPTICALMENT 
LICENSE-I-LOADED, DEC CRYPTICALMENT was successfully loaded with 460 units 
$ 

After you successfully register a license in the License Database (the default file specification is SYS$COMMON:[SYSEXE]LMF$LICENSE.LDB), you can enter the LICENSE LIST/FULL command to display the data in the database (see Example 5-3).

$  LICENSE LIST /FULL /AUTHORIZATION=USA126087 CRYPTICALMENT 

Use CTRL/Z to exit, PF3-PF4 for Previous-Next Screen and Arrow Keys to scroll.

When a license is successfully loaded with VMSLICENSE.COM or the LICENSE LOAD command, LMF displays an informational message.

5.4.6 Displaying License Information

To display information from the License Database about specific licenses, enter the LICENSE LIST command.

To display information in memory about loaded licenses, enter the SHOW LICENSE command. This command displays licenses loaded on the current node, and displays any reservation list associated with each license.

5.5 Loading a License

To allow users to access a product, you must load each registered license. Loading a license transfers data from the on-disk License Database into system memory. The following table shows the methods of license loading for LMF:

Figure 5-4 illustrates the license loading process for a standalone system. Whether the license manager enters the LICENSE LOAD command or the system automatically loads all registered licenses during startup, the license information is transferred to the system memory of node ART.

Figure 5-4 Loading a License

In an OpenVMS Cluster environment, multiple nodes load licenses from a single common database. LMF provides this capability to let you share licenses as well as control access to a product on a node-by-node basis (provided this is allowed by the terms and conditions of the license).

Typically, any node can load a license registered in the common License Database. For predictability, security, performance, or economic reasons, you can limit which nodes can access a product license intended to be shared among nodes. In an OpenVMS Cluster environment, you control access by modifying the license's include list. Use the LICENSE MODIFY command and either the /INCLUDE or /EXCLUDE qualifier to specify which cluster nodes can load the license. By changing the include list, you can create the effect of moving a product from node to node. Section 5.6.2 describes the process in detail. Note that you cannot share licenses that have the NO_SHARE option. They must be assigned to a single node.

You can also control which users in an OpenVMS Cluster environment can access a product license. Control access by modifying the license's reservation list. Use the LICENSE MODIFY command with the /RESERVE qualifier to specify which users can access the license.

In an OpenVMS Cluster environment, license loading involves transferring, or loading, license information from the on-disk License Database into system memory of the current node. The number and combination of licenses for an OpenVMS Cluster environment can be complex, which in turn makes the loading process complex and sometimes confusing. The general rule is that nodes specified on include lists or not specified on exclude lists of the LICENSE MODIFY command can load a registered license. As each system starts up, it loads any licenses to which it has access. If you need to load a license for all assigned nodes of a running cluster, you can use the OpenVMS System Management utility (SYSMAN), which is described in the HP OpenVMS System Manager's Manual. Figure 5-5 illustrates the loading process in an OpenVMS Cluster environment.

Figure 5-5 Loading a License in an OpenVMS Cluster Environment

See Section 5.6.2 for further details of license loading.

5.6 Managing Licenses After Registration

After you register licenses, you can manage them. While system managers can perform these tasks, managers of cluster environments and large multiple-user systems may also have an interest in managing products and product licenses.

For example, a cluster manager can use LMF to control which nodes can access a database product using important data (see Section 5.6.2). All system managers, however, may want to monitor license data using LICENSE commands.

VMSLICENSE.COM, LICENSE commands, and the DCL command SHOW LICENSE can perform most license management tasks, including:

• Listing registered licenses
• Showing loaded licenses
• Making loaded licenses unavailable --- either permanently or temporarily
• Transferring licenses from one database to another
• Modifying licenses --- such as termination dates or reservation lists

5.6.1 Restricting Product Use

The quickest method to restrict access to products registered in the License Database is to unload the license with a LICENSE UNLOAD command. The product becomes unavailable to new users and unavailable to all users when the last process using the product finishes. The product remains inaccessible until either you or the system reloads the license.

Although LICENSE UNLOAD is fast, it is not permanent. Typically, at system startup, LMF loads all the licenses registered in the License Database. In addition, a license that is loaded remains loaded until either the system is shut down or you intervene.

5.6.1.2 For Inactive Licenses

The following commands control license loading, which restricts product access. However, they do not unload loaded licenses or alter in-memory license data. For loaded licenses, use LICENSE UNLOAD.

• LICENSE DISABLE
  Prevents the specified license from being loaded until you enter a LICENSE ENABLE command.
• LICENSE MODIFY/INCLUDE, LICENSE MODIFY/EXCLUDE
  Makes the named nodes in an OpenVMS Cluster environment available or unavailable for license loading.
• LICENSE MODIFY/UNITS=number
  Limits access when you set the unit number to be less than that required by your processor or cluster.
  Use if your license has the MOD_UNITS option. Not all licenses have a specific number of units. Some licenses provide zero units, which is equivalent to unlimited units.
• LICENSE MODIFY/RESERVE=user-name
  Makes the product available only to the users named in the reservation list. You must use this method if your license has the RESERVE_UNITS option.
• LICENSE COPY
  Automatically disables a license as you reregister it in another License Database.
  This command is similar in effect to LICENSE DISABLE except that it also registers the license in the other database.
• LICENSE ISSUE
  Automatically disables a license so that you can then reregister it in another database.
  This command is similar in effect to LICENSE DISABLE except that it also produces a PAK replica to be registered elsewhere.
