Some things to consider before changing settings

Some things to take notice

1)-->/usr/lib/errstop (use carefully ,only in special cases)
Stops the error logging daemonn, disables diagnostic and recovery functions. The errorlog should never be stopped during normal operations.

2)The error log daemon must not be running when the errdead command is run

3)The bos.per.tools and perfagent.tools (filesets must be installed on the system to run
the topas.

4)Procmon tool(Graphical)
Must install below fileset
-bos.perf.gtools

5)The error log is never cleared unless it is manually cleared.
[Never use the cp /dev/null command to clear the error log . A zero length error log file
disables the error logging functions of the operating system and must be replaced from a
backup]


6)The command 'traceroute' (it creates load on system so don't use it on production server)


7)Don't run gated & routed at the same time on a host


8)ODM commands
When no option left then only then try odm commands
if used falsely the system might crash. So better wait for IBM SUPPORT.

9)Do not restart TCP/IP daemons, using the command
-->startsrc -g tcpip
It will start all subsystems defined in the ODM for the tcpip group, which includes both
routed & gated.

10)Do not run fsck command on mounted filesystem.
