Resource-information vector list

The resource-information vector list provides information about the application program that opened an ACB at execution time. The ACB's ACBRIVL field points to the list. The application program must search the vector list to find a particular vector.

For the complete layout of the ISTRIVL DSECT, see Resource-information vector list (ISTRIVL).

The resource-information vector list provides the following vectors:

Application-network name vector: This vector contains the network name of the application program LU. This name is specified by the name field of the APPL definition statement. The vector ID is X'02'.
Application-ACB-name vector: This vector contains the ACBNAME of the application program. This is the name specified by the APPLID operand of the ACB statement; if the ACBNAME operand is not present, the network name of the application program LU is used. The vector ID is X'03'.
Network-name vector: This vector contains the name of the network in which the host resides. This name is specified by the NETID start option; if the NETID start option is not specified, this vector contains 8 bytes of blanks. The vector ID is X'06'.
SSCP-name vector: This vector contains the name of the SSCP. This name is specified by the SSCPNAME start option. The name contained in this vector is used to identify the SSCP to the NetView® program. The vector ID is X'07'.
Host-subarea-PU-network-name vector: This vector contains the network name of the host subarea physical unit (PU) contained in this host. This name is specified by the HOSTPU start option; if the HOSTPU start option is not specified, this vector contains the default host subarea PU name, ISTPUS. This name is part of the session awareness data provided to the NetView program or session monitor when a resource is contained within the subarea of the host PU. The vector ID is X'08'.
Host-subarea-PU-network-address vector: This vector contains the network address of the host subarea PU. The vector ID is X'09'.
Maximum-subarea vector: This vector contains the maximum subarea number (in binary) that is valid for this host's domain. This is obtained from the MAXSUBA start option. The vector ID is X'0A'.
LU 6.2-application-definition vector: This vector is present in this list for LU 6.2 application programs. The LU 6.2 application program may use this vector to determine the values coded on the APPL definition statement.
For more information about the APPL definition statement, refer to the z/OS Communications Server: SNA Resource Definition Reference. The vector ID is X'0B'.
Common-application-definition vector: This vector is present in this list for all application programs. The application program may use this vector to determine the values coded on the APPL definition statement.
For more information about the APPL definition statement, refer to the z/OS Communications Server: SNA Resource Definition Reference. The vector ID is X'0C'.
The APPCCMD-vector-area-length vector: This vector is present in this list for LU 6.2 application programs. It contains the absolute minimum length and the recommended minimum length for full use of the APPCCMD vector area. The vector ID is X'11'.
Application-to-VTAM-vector-keys vector: This vector contains a list of all ACB vector keys presented by the application program on the Application-ACB vector. The vector ID is X'12'.
Performance monitor vector: This vector, if present, identifies any fields in the performance data parameter list of the installation-wide performance monitor exit routine (ISTEXCPM) that are no longer supported. The vector points to a table of field entries, each of which contains information needed to locate the position of the unsupported field within the affected vector. Refer to z/OS Communications Server: SNA Customization for more information. The vector ID is X'13'.
