Nways RMON and JPM Questions(NT, AIX)

Topic thread:
NWAYS CAMPUS MANAGER SUITE FOR AIX
NWAYS CAMPUS MANAGER LAN AIX
I am planning the installation of Nways campus LAN , Remon and Traffic
Monitor on AIX 4.3.2
I have several questions regarding the directory location where these
products and their pre-reqs (i.e. DB2) are installed.
1) Can the default directory where the above Nways components are
installed be specified or changed ? i.e
install all NWAYS components (includind remon and traffic mon. onto
/usr/ntmgmt/nways )
2) It appears DB2 places itself onto /usr/lpp/db2_05_00 . Can this
be changed ?
3) If DB2 is installed somewhere other than default does NWAYS care ?
can NWYS be adjusted for this change of DB2 location ?
A:
The install locations for Nways are not specifiable, i.e., you cannot
tell Nways where to install. However, you can create the directory
"mount points" ahead of the install in a separate filesystem or as
a link to the location in the filesystem you desire and it will appear
in the actual space you specify but Nways will know it as its location
using the link. Example, Nways installs in "/usr/CML/....". You could
create 1) a separate filesystem and mount at "/usr/CML/....", OR,
2) you could create a softlink (ln command) ahead of install that linked
"/usr/CML/..." to /usr/whatever.... and Nways would actually put the
code into the location you desired. This way you would not have to
change any reference environment variables required by Nways.
I don't know about DB2 options. It does install in /usr/lpp/db2_05_00.
You can use the same "tricks" for this and it should work as well. Check
with DB2 support to see if there is an option for its install location.
DB2 uses an AIX UID for the instance owner(nwaysdb2) and an AIX UID
for the DB2 Administration Server. These are normal AIX UIDs and are
located in /home filesystem. The actual location of the DB2 code could
be anywhere as far as Nways is concerned. DB2 has environment variables
that specify where it is located that you set in profiles. Check with
DB2 support if actually moving its code location other than just using
a softlink.

Q:
If I decide to go the softlink (symbolic link??) route, is linking my
destination i.e. /usr/ntmgmt/CML to /usr/CML enough ?
i.e. are there no other directories nways files are located in ?
also should i change the permissions on this newly created directory
/usr/ntmgmt/CML ?
A:
No, there are several directories to consider:
/usr/CML
/usr/CML/OStore/cache (created as separate filesystem by the install)
/usr/rabmv2/cache (if you plan to install RABM...replaced by JPM)
/usr/lpp/ODI (the OBjectStore Db installed/used by Nways)
/usr/lpp/mgtapptran (the Application Transported subsystem installed
and used by Nways)
/tmp/ostore (setup and used by the ObjectStore product)
As you can see, there several places to consider, making the administrat
ion of the system much more difficult. The most important part is
getting these individual filesystems/directories/links established
properly before install.
The permissions should be fine if using UMASK 022. You will otherwise
have to "chmod" them to match the original file & directory values.
I have installed using this method of separate filesystems and it
worked fine. I would guess the links to be successful as well but I
have not done it.

Q:
In liu of multiple links for DB2 and NWAYS which could be quite messy
let's say i install these two apps. in their default locations.
My objective is to collect a treamendus amount of networks statistics
(i.e. MIB data from traffic monitor and remon) in which I beleive
DB2 will store.
1) Am I correct in assuming DB2 stores these data (i.e mib data which
can be graphed) ?
2) Can I direct remon, Traff mon or DB2 to store them not where DB2
or Nways is installed but a different directory on my RS/6K where I
have plenty of spcae ?
A:
The idea to build separate filesystems for the data storage is a good
idea.
For Nways, the Java Performance Monitor(JPM) uses a JDBC-compliant
relational database. DB2 is shipped with the purchase of Nways as this
solution. If DB2 is already in use on the platform, you can create the
instance in the present installation. From a fresh DB2 install, you
would want to "isolate" /home/nwaysdb2 as a filesystem.
TrafficMonitor has its own built-in RDB(Informix) that has a "maximum"
size to be configured. Check the TrafficMon docs...anyway, you could
also "isolate" the database even though its size would be bounded.
For ReMon, consider "isolating" the "Reports" directory under
/usr/LANReMon/rmon/LOGDIR depending on how much your collecting.
See the User's Guide for any additional info.

Q:
Thanks for the detailed answer. i've looked at all the user's guides
avaialble (Remon, Traf. mon, could'nt find one for Nways) and have the
following questions:
1) Appendix C and G of the Trafmon. indicates that the database location
for traffmon. is in /usr/LANRemon/trafficom/tfm.dbs
So I interpret this as the location where all the long term trend
statistics is stored. Is this correct ?
If this is correct it just does not make sense to me why this suite of
applications (nways, remon and trafficmon. spread themselves and
databses all over the filesystem ???¢¢)
2) looking at AIX remon guide it does not mention any data base location
Can this be because traffmon and remon use the same informix database ?
3) If the answer to #2 is negative then what database engine does remon
use?
4) I have experience with he NT version of remon that uses MS acccess
as it's database. It appears to me if the AIX version of remon is
anything similar to the NT version then there will be some redundancy in
long term collection and trending between these two apps. Am I correct
in making this assumption ?
5) In reference to the nways JPM JDBC database it appears that it's
function agian is somewhat redundant if remon and trafmon. are
operational. Is this a correct assumption ?
A:
1)The doc indicates the directory you cite. Also documented is the
ability to specify an alternate location.
2,3)LANReMon does not use the Informix DB. It creates so-called ".csv"
files, i.e., comma-separated-varible files.
4) yes, same results basically, just different user interfaces.
The NT ReMon has reporting capability...not on AIX.
5) somewhat redundant...except, JPM can monitor, graph and report on
ANY MIB variable although "reasonable" MIB variables are pre-described.
ReMon can only monitor RMON variables. Again, the AIX ReMon does not
have the reporting capability of the JPM nor the NT ReMon.
