Managed Component, Concept of Managed Components
The “Managed Component”, MC, is a “Managed Object”, i.e. an entity that is manageable. The MC is a set of one or more processes. One process can not exist in several MCs. The MCs is the smallest logical entity a system administrator has to manage.
MC
Self Management Service The following services are covered by self-management: Start/Stop/Restart Start, Stop and Restart MCs Product Inventory To see what is installed in the O&M system. System Logging Logging of normal system events in the O&M system. Error Handling Logging of abnormal system events in the O&M system. Alarms Generate alarms from errors. SW Trace Start, stop and collect debugging printouts in O&M applications. Self Test Perform self-tests on MCs. Instrumentation Get run time values, e.g. queue length. Configuration Handling of configuration parameters.
Self Management CLI If and when it is impossible to start a graphical user interface you can also control most self management features from a command line interface: #/opt/ericsson/nms_cif_sm/bin/smtool ( Nowdays ’smtool’ is in $PATH ) Using this tool you can for example:
•View status of MCs •Start/Stop/Restart MCs •Display/Set configuration parameters •Start/Stop CIF Trace for MC[s] You might also want to take a look at a similar unofficial tool: #/opt/ericsson/sck/tmp/ssr.sh
Self Management CLI smtool command examples: smtool list smtool list | grep –v started smtool offline sdm smtool online sdm smtool warmrestart eam_handlerMtp smtool coldrestart FM_DistributionServer smtool trace ARNEServer 1-199 arne_trace.log smtool trace stop smtool cancel text in RED are examples of MCs
Lists status off all MCs Lists not started MCs Re-reads MC / process configurations Same as offline + online smtool trace Cancels ongoing start/stop of MCs

What is SMIA ?
Performance Management - SMIA • SMIA – Statistical Initiation and Administration Tool • SMIA is an tool which facilitates Initiation and Administration of statistical measurements towards Network Elements built on the AXE platform • Part of the performance management suite of applications (Network Statistics - NWS) in the OSS RC

Description
Command Daily Tasks # uptime
Check the Server’s uptime on daily basis to verify that whether it has been rebooted without the administrator’s knowledge.
# iostat -E
Verify that all the physical disks or disk arrays are having any Soft Error, Hard Errors or Transport Errors.
# /usr/platform/sun4u/sbin/prtdiag –v
Verify that all the system components, like CPU, Amount of Cache, Cooling FAN, Power Supplies etc., are working properly.
# vmstat
By means of the UNIX command `vmstat' it is possible to identify if a performance problem is caused by a shortage of memory or CPU power.
# prstat
Use the following command to monitor which application/process is using the CPU resource most. It is a real time CPU monitoring sun command.
# tail –1000 /var/adm/messages | more
Logically read the system generated administrative message which gives the information for the successes and failures occurred during operation. Very useful for troubleshooting.
# df –k
To determine the amount of disk space available and used on the file system.
# du –k
Check the amount of disk space in number of 1 Kbytes blocks used by the current directory and subdirectories if you have space problem for file systems.
# vxprint
Check the Status of the Disks Under Veritas Control, all disks must show Okay status.
# vxdisk list
Check the status of mirroring.
# vxprint –p # vxprint –ht # /opt/ericsson/nms_cif_sm/bin/smtool list
Check that all processes are running in CIF Management Console. Open the CIF Management console and observe that all the processes are online.If offline, make them as online.
# /opt/versant/ODBMS/bin/dblist
Check the status of the versant databases whether it is active or not.
# more /var/opt/ericsson/sdm/log/SDM_GRAN_dispatcher.log
Read SDM error reports messages for statistics data missing & other messages.
# cd /var/opt/sybase/sybase/log
Check the Sybase error log
# /ericsson/syb/util/db_check.sh
Check database space.
# isql –Usa – w2000 –Psybase11 1> sp_helpdb 2> go
Check None of the Databases should be Offline.
# df # df # df # df # df # df # df

Check Remaining disk space on sybase filesystem.
# cd /var/opt/ericsson/sgw/outputfiles/apg40files/sts
Observe the latest time stamp of the files coming from APG40.
# isql –Usa –w2000 –Psybase11 1> use bsddb 2> go 1> select max(TIME), NE from CELL_ADM where RES=1 group by NE
Verify that the STS data coming from the nodes are getting loaded properly in the database/Sybase for each of the active nodes
Description
Command
Weekly tasks
# cd /var/opt/ericsson/sybase/sybase/dumplogs/ # ls –la syb_dbdump*
# find / -type f -name core
# find / -type f -size +10000000c -ls.
# df –k /export/dbdumps/
Check the weekly database dump succeeded in directory
Scan & Delete Core Files
Scan filesystem for large files and delete them if not required.
4.2.3 Check the Space Availability for Automatic Database Dumping, Make sure there is enough disk space left for the automatic database dumps.
Delete or archive FMA and EAC logs in log administration
Monthly Tasks
# rm /var/opt/ericsson/cna/log/reports
Remove the CNA printouts, Check that all adjustment and update jobs are completed before removing them.
Clean the RNO Database
Delete the older and unwanted RNO recordings from the RNO GUI for smooth operation of RNO.
# cd /ericsson/dmr/log # ls –lrt db_dump*
Check the backup log files
