2.2.50 Operands related to a client group

220) pdcltgrp -g client-group-name -u guaranteed-number-of-connected-users-per-group
This operand is specified when the connection frame guarantee facility for a client group is used. For details about the connection frame guarantee facility for a group, see the HiRDB Version 9 System Operation Guide.
-g client-group-name ~<alphabetics>((1-2 characters))
Specifies the name of a client group.

X/Open XA interfaceXA#1Client that accesses HiRDB via the X/Open XA interface. Even if the client is a PC or WS, the client group is XA as long as the X/Open XA interface is used for accessing HiRDB.

#1: To specify this client group, the HiRDB client version must be one of the following:
  • 04-05 (cannot be specified for 05-00 or 05-01)
  • 05-02 or later
#2: To specify this client group, the HiRDB client version must be the following:
  • 04-00 or later
#3: Up to 10 user-defined groups can be specified.
#4: The client group name specified here is specified for the PDCLTGRP operand of the client environment definition. If the values specified for the pdcltgrp and PDCLTGRP operands do not match, the value specified here is ignored.
-u guaranteed-number-of-connected-users-per-group
~<unsigned integer>
  • For a HiRDB single server configuration: ((1-2999))
  • For a HiRDB parallel server configuration: ((1-1999))
Specifies the number of connected users for the client group.
Even when accesses to HiRDB from other client groups or utilities are concentrated, the users (up to the number specified here) from the applicable client group are guaranteed access to HiRDB.
Notes
  • The total number of users specified by the -u option must not exceed the value specified in the pd_max_users operand; otherwise, HiRDB will not start.
  • This facility is applicable only to the database definition utility.
Effects on individual estimation formulas
If the value of the pdcltgrp operand is changed, the following estimation formulas are affected:
