System Data Item Descriptions
$ Associated with the response to an AUTO; WRITE command (set by an AUTO; WRITE
command in the OLTP Client)
LENGTH = 8 EDIT = A
GLB.OLTPVALUE
GLB.ORIGIN
This read/write System Data item contains the OLTP application-defined return code:
$ Given in the server, to be returned to the client
$ Received by the client
This value is attached to the response when a server replies to an OLTP-initiated message,
and is made available in GLB.OLTPVALUE following the AUTO; WRITE command in the
OLTP client transaction.
GLB.OLTPVALUE is initialized to zero at the beginning of a transaction in both client and
server, and is set by an AUTO; WRITE command for an OLTP client transaction.
(GLB.OLTPVALUE is not set by a non-OLTP AUTO; WRITE command.)
LENGTH = 9 EDIT = S
GLB.ORIGIN is a read-only System Data item that contains the name of the LINC database
from which an Automatic Entry originated. You can compare it to the System Data item
GLB.SELF in your logic, to detect if an Ispec is receiving an Auto Entry from another LINC
System or not.
GLB.ORIGIN is not implemented in LDA Run Time.
See also the GLB.ORIGINENV and GLB.ORIGINHOST System Data items.
LENGTH = 10 EDIT = A
GLB.ORIGINENV
This read-only System Data item is used only with external Automatic Entries from LINC
Systems in OS 2200 or UNIX environments.
The value of an Automatic Entry from an OS 2200 environment specifies the originating
LINC Environment.
The value of an Automatic Entry from a UNIX environment specifies the ORACLE SID (or
Griffin Universe) of the database for the originating LINC System.
The value of an Automatic Entry from an MCP based LINC System is spaces.
