14.1 Performing main server and database redundancy switches
In a redundant 5620 SAM system, performing regular main server and database
redundancy tests is important for the following reasons:
• to ensure that 5620 SAM server and database redundancy functions correctly and
responsively
• to identify conditions that may interfere with a 5620 SAM upgrade
14.2 Checking the 5620 SAM platform performance
Use the following procedure to test the 5620 SAM platform performance and to
record base measures. You can compare performance monthly to:
• collect base measure information related to platform performance
• ensure that there is no degradation in performance
If the performance degrades, collect the necessary logs and performance data and
contact Alcatel-Lucent technical support. See the 5620 SAM Troubleshooting Guide
for information about 5620 SAM log collection.
Procedure 14-1 To measure 5620 SAM platform performance
1 Log into the main server, auxiliary server, 5620 SAM database, or auxiliary
database station as the root user.
2 Open a command window.
3 Enter the following to check CPU usage per process:
# top ↵
Depending on your system configuration, approximately the top 20 processes are
displayed.
4 Review the output.
The top 5620 SAM process listed under the CPU column should be the Java process.
However, the Java process should not consume the majority of CPU cycles
compared to previous base measures. Some database processes may also take CPU
time, depending on the system load.
5 Record the data for future performance comparison.
6 Press CTRL-C to stop the command.
Note — Alcatel-Lucent strongly recommends that you perform a
main server activity switch and a database switchover monthly, or at
least quarterly, if a monthly test is not possible. See Chapter 8 for
information about performing a server activity switch or database
switchover. Contact your Alcatel-Lucent technical support
representative for further assistance.
