Handling database inconsistency

20

Question:
When running the dbms-compare or dbms-compare-all command to compare databases of a NE, inconsistency between database drdb, mdb, fdb0, and fdb1 is found.
Answer:
It is normal. The root cause is that the storage unit refresh rates of databases are different. Database mdb is stored in the memory. Database drdb is stored in the NVROM. The storage unit refresh rates of these two databases are fast. However, database fdb1 and fdb0 are stored in the flash, which has a slow refresh rate.
For frequently changed data, storage database and flash database are inconsistent after changes. The ALC database information, such as node output power, variable optical attenuator (VOA) attenuation, reference node wavelengths and power, and especially the output power, is changed frequently.
