(3) DF/UX Extension distribution definition
(4) Package creation

(1) DF/UX Extension installation

In the case of a HiRDB/Single Server, install DF/UX Extension at the server machine where the single server is defined.

In the case of a HiRDB/Parallel Server, install DF/UX Extension at the server machine where the front-end server is defined.

(2) DF/UX Extension environment definition

The HiRDB-related operand for the DF/UX Extension environment definition is explained below.

maximum_client_users must be set so that the following condition is satisfied:

Formula

Value of pd_process_count (single server definition*)
[Figure]value of maximum_client_users (DF/UX environment definition)
+ value of maximum_server_users (DF/UX environment definition)
+ value of maximum_client_users (DF/UX Extension environment definition)

* In the case of a HiRDB/Parallel Server, use the value in the front-end server definition.

(3) DF/UX Extension distribution definition

The following operand must be specified in the DF/UX Extension distribution definition:

OperandSpecification
rdb_nameMust be the same RD node name specified in the SQL statements.

(4) Package creation

DF/UX Extension's package handling utility is used to create a package used by DF/UX Extension. The following points should be noted.

  1. When DF/UX Extension's package handling utility creates cursor declarations in the package, it uses C00001-C00100 as the cursor names. However, any cursor names can be used in cursor declarations in a UAP. HiRDB converts the cursor names in the UAP to the cursor names in the package.
