Description: Some utilities provided by Communications Server require the use of certain configuration files. You are responsible for providing these files if you expect to use the utilities. IBM® provides default configuration files as samples in the /usr/lpp/tcpip/samples directory. Before the first use of any of these utilities, you should copy these IBM-provided samples to the /etc directory (in most cases). You can further customize these files to include installation-dependent information. An example is setting up the /etc/osnmpd.data file by copying the sample file from /usr/lpp/tcpip/samples/osnmpd.data to /etc/osnmpd.data and then customizing it for the installation.
If you customized any of the configuration files that have changed, then you must incorporate the customization into the new versions of the configuration files.
Element or feature: | Communications Server. |

Timing: | Before the first IPL of z/OS V2R1. |
Is the migration action required? | Yes, if you have customized a configuration file (listed in Table 1) that IBM has changed. |
Target system hardware requirements: | None. |
Target system software requirements: | None. |
Other system (coexistence or fallback) requirements: | None. |
Restrictions: | None. |
System impacts: | None. |
Related IBM Health Checker for z/OS check: | None. |
Steps to take: If you added installation-dependent customization to any of the IBM-provided configuration files listed in Table 1, make the same changes in the new versions of the files by copying the IBM-provided samples to the files shown in the table and then customizing the files.
Utility | IBM-provided sample file | Target location | What changed and when |
---|---|---|---|
SNMP agent | /usr/lpp/tcpip/samples/osnmpd.data | /etc/osnmpd.data | Every release, the value of the sysName MIB object is updated to the current release. |
