Field Descriptions

Bytes available. The number of bytes of data available to be returned. All available data is returned if enough space is provided.

Bytes returned. The number of bytes of data returned.

Compliance type. The compliance type associated with this license. The compliance type determines the action taken when the value of the usage limit field is exceeded.

The valid values are:

01 The usage limit cannot be exceeded. The user who attempts to use the product or feature after the usage limit has been reached is prevented from accessing it. The product or feature cannot be accessed until the appropriate action is taken to increase the usage limit of it. A message indicating an attempt was made to exceed the usage limit is sent to each of the following:
  • The QSYSOPR message queue
  • The message queues specified on the Change License Information (CHGLICINF) command.
02 The user who attempts to use the product or feature after the usage limit has been reached is allowed access. A warning message indicating the usage limit is exceeded is sent to QSYSOPR and to the message queues specified on the Change License Information (CHGLICINF) command.
03 To use a product or feature with keyed compliance, the license must be installed using one of the following:
  • A valid license key through the Add License Key Information (ADDLICKEY) command.
  • The Add License Key Information (QLZAADDK) API.
This license key is provided by the software provider. The key ties the usage limit to the particular product or feature and to a particular system serial number. To change the usage limit, a user must get a new key from the software vendor. A user can use the product or feature after the usage limit is reached. However, the user is allowed access to the product or feature for only the number of days contained in the product's grace period. Once the grace period has expired, no users over the usage limit are able to use the product or feature until one of the following happens:
  • A new license key is received from the software provider.
  • The number of users fall below the usage limit.
A warning message indicating that the usage limit has been exceeded is sent to each of the following:
  • The QSYSOPR message queue.
  • The message queues specified on the CHGLICINF command.

Date grace period expires. The date that the grace period expires. Once a user has exceeded the usage limit, the date the grace period expires is set using the grace period and the current date. Before the grace period expires, a new license key needs to be obtained from the software vendor. If this is not done, users exceeding the usage limit are not allowed access to the product or feature.

9999999 This value indicates no grace period or that the grace period has expired.
CYYMMDD The date the grace period expires. C is the century, YY is the year, MM is the month, and DD is the day. The date must be numeric as follows:
  • Century, where 0 indicates years 19xx and 1 indicates years 20xx.
  • Month may not be greater than 12.
  • Day may not be greater than 31.

Expiration date. The date the license will expire. The valid values are:

CYYMMDD C is the century, YY is the year, MM is the month, and DD is the day. The date must be numeric as follows:
  • Century, where 0 indicates years 19xx and 1 indicates years 20xx.
  • Month may not be greater than 12.
  • Day may not be greater than 31.
9999999 The license does not have an expiration date.

Feature. The feature of the product. Valid values for the feature are 5001 through 9999.

Grace period. The number of days after a product first exceeds its usage limit that a user has to obtain a new license key. Before the grace period expires, a new license key needs to be obtained from the software vendor. If this is not done, users exceeding the usage limit are not allowed access to the product or feature. The date the grace period expires is calculated by adding the number of days in the grace period to the current date.

Last peak date and time. The date and time when the peak usage of the product or feature last occurred since the peak usage was reset to zero. In the CYYMMDDHHmmSS format as follows:

C Century, where 0 indicates years 19xx and 1 indicates years 20xx.
YY Year
MM Month
DD Day
HH Hour
mm Minute
SS Second

Last update date and time. The date and time when the usage limit was last updated. In the CYYMMDDHHmmSS format as follows:

C Century, where 0 indicates years 19xx and 1 indicates years 20xx.
YY Year
MM Month
DD Day
HH Hour
mm Minute
SS Second

Length of each current license user record. The length of each current license user record. This is the length of the license user plus the length of any additional license user information.

Length of each license user. The length of each license user. This is the same value that is used during the request and release of this product. This may be a value of 1 through 80.

License term. The extent of time the authorized usage limit for a product lasts. Each time a new license term is installed for a product, the authorized usage limit must be set by doing each of the following:

Possible values are:

Vx The authorized usage limit is valid only for the entire version of the product or feature.
VxRy The authorized usage limit is valid only for the entire release of the product or feature.
VxRyMz The authorized usage limit is valid only for the modification level of the product.
Where the x and y can be a number from 0 through 9. Z can be a number 0 through 9 or a letter A through Z.

License user. A user that currently holds one or more uses of the product or feature.

List of current license users. A list of all the current users of the product.

Message queue library name. The library where the message queue resides.

Message queue name. The name of message queue.

Number of current license users. The number of current license users in the list.

Number of message queues. The number of message queues in the list.

Number of uses held. The number of license uses held by this license user.

Offset to current license user list. The offset from the beginning of the receiver variable to the start of the first current license user. This offset is 0 if there are no license users or if the size of the receiver variable is not large enough to hold any license users.

Offset to message queue list. The offset from the beginning of the receiver variable to the start of the first message queue name and library. This offset is 0 if there are no message queues or if the size of the receiver variable is not large enough to hold any message queues.

Peak usage. The maximum number of license users that have accessed the product or feature at one time. The peak usage may be reset using option 10 of the Work License Information (WRKLICINF) command. If the product is using processor usage type, the peak usage value will be rounded up to the next whole number. For instance, an actual peak usage of 2.15 would round up to 3. See the processor peak usage count field for the processor peak usage count in hundreths of a processor.

Processor group. The processor group of this system. A processor group is the grouping of system model numbers by relative processor size.

Processor usage count. The processor usage count is the number of hundreths of processors in the logical partition configured at the time the product was used. This field is set to 0 for products that do not have a processor usage type.

Processor peak usage count. The maximum processor usage count in hundreths of processors. The processor peak usage may be reset using option 10 of the Work License Information (WRKLICINF) command. This field is set to 0 for products that do not have a processor usage type.

Product ID. The product ID of the product or feature whose license information is to be retrieved.

Product license information handle. The product information handle is passed back. It may be used within the application to verify that the product attributes are the same as the original license information created by the software provider. This handle will not be stored and will be generated each time license information is retrieved.

Release level. The version, release, and modification level of the product whose license information was requested. This is returned in the receiver variable parameter. If you specified *ONLY in the release field of the LICP0100 format, the actual release level is returned here.

Reserved. If this field is input, character fields must be set to blanks and binary fields must be set to hexadecimal zeros.

Threshold value. The threshold for this product or feature.

The threshold indicates you want a message sent to the system operator message queue stating that a product or feature is reaching the usage limit.

-1 The threshold value is *NOMAX.
0-999999 The threshold value.

Usage count. The usage count for the product or feature at the time of the retrieve operation. Valid values are 0 through 999999. If the product is using processor usage type, the usage count value will be rounded up to the next whole number. For instance, an actual usage count of 2.15 would round up to 3. See the processor usage count field for the processor usage count in hundreths of a processor.

Usage limit. The usage limit for this license.

-1 Any number of users are allowed to access the product or feature.
0-999999 The number of users allowed to access the product.
