z/OS NFS server debug trace capture
The z/OS NFS server records z/OS NFS debug trace diagnostic information to the z/OS component trace buffer. z/OS NFS error and informational messages are also recorded to the z/OS component trace buffer or to the server log data sets. When recording debug trace diagnostic information, IBM recommends that the z/OS component trace buffer be used to minimize the performance impact of collecting these extra diagnostics. To record z/OS NFS server debug trace diagnostic information in the z/OS component trace buffer, see Using z/OS component tracing.
MODIFY mvsnfs,LOG=msgtype
where mvsnfs is the name
of the z/OS NFS procedure in the PROCLIB and msgtype is ERROR, WARN, or INFO.The trace records are buffered in storage. The current buffers must be flushed to disk and then the log data sets must be swapped. After swapping, the desired log data set must be copied to disk before it is overwritten by toggling back to the previous log data set by the automatic toggle mechanism.
MODIFY mvsnfs,FLUSHLOG
where mvsnfs is
the name of the z/OS NFS procedure in the PROCLIB.This command enables a TSO/E user to browse all the log records that have been written by the Network File System.
MODIFY mvsnfs,SWITCHLOG
where
mvsnfs is the name of the z/OS NFS procedure in the PROCLIB.MODIFY mvsnfs,LOG=INFO
where mvsnfs is
the name of the z/OS NFS procedure in the PROCLIB.MODIFY mvsnfs,INITLOG
where mvsnfs is
the name of the NFS procedure in the PROCLIB.
