If the SNMPD.CONF information is located in an MVS™ data set rather than a z/OS® UNIX file,
special considerations must be made to support dynamic configuration
changes to the SNMP agent's configuration. If dynamic configuration
changes are made, the file is rewritten to reflect the changes. Therefore,
consider the following items when allocating the SNMPD.CONF file to
an MVS data set:
- The record length (LRECL) should be 512 bytes to accommodate the
longest possible entry.
- The use of a member of a partitioned data set is tolerated but
not recommended. Because the file might be rewritten often, frequent
compression of the partitioned data set may become necessary. In addition,
locking on the file is done at the data set level, not at the member
level, so other members of the partitioned data set would not be usable
while the SNMP agent was running (after a dynamic configuration change
had been made).
