2.7.74 DBOSYNC
Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC 1 800 553-2447.
2.7.74 DBOSYNC
Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Object: NE
The Standby Database Out Of Synchronization alarm occurs when the standby TCC2/TCC2P database
does not synchronize with the active database on the active TCC2/TCC2P.
Caution If you reset the active TCC2/TCC2P while this alarm is raised, you lose current provisioning.
Clear the DBOSYNC Alarm
Step 1 Save a backup copy of the active TCC2/TCC2P database. Refer to the “Maintain the Node” chapter in
the Cisco ONS 15454 Procedure Guide for procedures.
Step 2 Make a minor provisioning change to the active database to see if applying a provisioning change clears
the alarm:
a. In node view, click the Provisioning > General > General tabs.
b. In the Description field, make a small change such as adding a period to the existing entry.
The change causes a database write but does not affect the node state. The write could take up to a
minute.
Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC 1 800 553-2447.
