Note:

This procedure may be performed outside of the maintenance window.

Table 3-7 Procedure 2 PRE-MIGRATION SYSTEM HEALTH CHECK

STEP #	This procedure determines the health of the MPS before and after Migration. Estimated time: 5 minutes
☐1.	MPS A and B: Log in to the server as the user “root”.	Login: root Password: <root_password>
☐2.	MPS A and B: Validate date, time and time zone to ensure accuracy.	# date Thu May 12 05:55:27 EDT 2016
☐3.	MPS A and B: Run the “hastatus” command to verify the HA state of this server.	Run the following command on both LSMS A and B to verify the HA state of mated LSMS pair. # hastatus Verify that the hastatus of one of the servers is Active and the other is Standby. WARNING: If the output from the above command is anything else other than “ACTIVE” and “STANDBY”, do not proceed with this procedure and contact My Oracle Support following the instructions on the Appendix E.
☐4.	LSMS Standby server: Verify that the STANDBY server’s MySQL replication is functioning properly.	Run the following command to verify that MySQL replication is working correctly on the STANDBY LSMS server: # tail /var/TKLC/lsms/logs/dbreplMon.log If MySQL replication is functioning correctly then the following output will be observed, make sure that at least the last line of your output matches the lines below. Thu Dec 07 05:58:12 2017 All tests passed on STANDBY Thu Dec 07 05:59:19 2017 All tests passed on STANDBY Thu Dec 07 06:00:25 2017 All tests passed on STANDBY Thu Dec 07 06:01:32 2017 All tests passed on STANDBY WARNING: If at least the last line of your output does not match the lines above then do not proceed with this migration and contact My Oracle Support following the instructions on the Appendix E.
5.	LSMS Active server: Verify that the ACTIVE server’s MySQL replication is functioning properly.	Run the following command to verify that MySQL replication is working correctly on the ACTIVE LSMS server: # tail /var/TKLC/lsms/logs/dbreplMon.log If MySQL replication is functioning correctly then the following output will be observed, make sure that at least the last line of your output matches the lines below. Thu Dec 07 05:58:12 2017 All tests passed on ACTIVE Thu Dec 07 05:59:19 2017 All tests passed on ACTIVE Thu Dec 07 06:00:25 2017 All tests passed on ACTIVE Thu Dec 07 06:01:32 2017 All tests passed on ACTIVE
		WARNING: If at least the last line of your output does not match the lines above then do not proceed with this migration and contact My Oracle Support following the instructions on the Appendix E.
☐6.	MPS A and B: Run syscheck	# syscheck Running modules in class disk... OK Running modules in class services... OK Running modules in class system... OK Running modules in class lsmshc... OK Running modules in class hardware... OK Running modules in class proc... OK Running modules in class net... OK LOG LOCATION: /var/TKLC/log/syscheck/fail_log
☐7.	LSMS Active server: Capture the output of ‘sentry status’ command	Run the following command on the ACTIVE LSMS server to display the current LSMS sentry status: # sentry status Note: Verify that the output displays a Status of “running” for all processes; the regional processes (npacagents) may or may not be associated in the Comment field. If the output from this command displays any other Status than “running” contact My Oracle Support following the instructions on the Appendix E. Capture the output from this command and make it available to Oracle Technical Services if required.
8.	LSMS Active server: SSH to NAS server and execute syscheck.	# ssh backupserver # syscheck Running modules in class disk... OK Running modules in class services... OK Running modules in class system... OK Running modules in class lsmshc... OK Running modules in class hardware... OK Running modules in class proc... OK Running modules in class net... OK LOG LOCATION: /var/TKLC/log/syscheck/fail_log
☐9.	Note down the Time zone	Note the time zone which will be required to be configured post migration. # su - lsmsmgr Select Server Configuration and press [ENTER]. Select Time Zone and press [ENTER]. The screen shows the current time zone setting.
10.	Repeat on the day of the scheduled Migration	All Health Checks should be repeated the day of the migration. If any problems are encountered, resolve before proceeding further.
This procedure is complete!
