Overview
1.7 SNMP Versions
If you have problems running images linked against an older version of UCX$ESNMP_SHR.EXE, verify that the version in SYS$SHARE is the latest by entering the following DCL command:
$ DIRECTORY/DATE SYS$SHARE:*$ESNMP_SHR.EXE
The creation dates of the files with the prefix TCPIP$ and UCX$ should be within a few seconds of each other, and only one version of each file should exist. Make sure both images include the file protection W:RE.
–You should relink and perhaps recompile images associated with ECOs for Version 4.1 or 4.2 other than those discussed in the previous list item.
Images linked against object library (.OLB) files may not need to be relinked, although you can relink them against the shareable images in this version of the product to decrease the image size. Relinking against the shareable image allows you to take advantage of updated versions of the eSNMP API without the need to relink. Some images linked against the current version of TCP/IP Services may run under Versions 4.1 and 4.2, but this backward compatibility is not supported and may not work in future versions of TCP/IP Services.
If an existing subagent does not execute properly, relink it against this version of TCP/IP Services to produce a working image. Some subagents (such as the OpenVMS Server MIB) require a minimum version of OpenVMS as well as a minimum version of TCP/IP Services.
1.8 For More Information
This manual provides the OpenVMS information required for implementing eSNMP subagents and ensuring their proper operation in that environment.
The eSNMP software for OpenVMS is derived from the Compaq Tru64 UNIX product. For information about the architecture and for details about the eSNMP API, refer to the UNIX documentation at the following URL:

For information about prototypes and definitions for the routines in the eSNMP API, see the TCPIP$SNMP:ESNMP.H file. Table
