叶军, 文英, 蒙丽彬, et al. Research and application of memory database high availability on business operating support system[J]. 2016, 29(4): 12-17. DOI: 10.13992/j.cnki.tetas.2016.04.003.
MDB high availability is realized by adopting MDB mirror data and redo log to recover. It is timeconsuming and possibly losing some data. Therefore
it can’t meet the needs of telecommunication service. Based on current processing procedure in the BOSS
it adds MDB monitor and MDB daemon. And it is implemented by MDB active standby two-machine high availability based on network to process transaction synchronously in real time and switch in abnormity. The data of measure and application shows that it is switched seamlessly to standby MDB when the active MDB is abnormal. It ensures data integrity without drop out and process efficiency without obvious decrease. And it is effective in MDB high availability and service continuity.
