Description
Technical field
The present invention relates to database resource pond management domains, and in particular to a kind of reality in the database resource pond of intelligence manufacture
When synchronous method and device.
Background technique
VM (Visual Manufacturing and workshop management Visual Manufacturing&Shop Floor Management) is claimed
For " nervous system " at Workshop scene, it is provided by more intuitive three-dimensional scenic mode to enterprise customer policymaker true
Task, personnel and device status information, be the management method for being effectively improved enterprise manufacturing process.
By the collection and feedback of creation data in manufacturing process and information, processing tasks can be created, be distributed, with
Track and report completion management.Plan and actual construction time, plan and actual production for task, it is qualified with the essential informations such as scrap
Unified maintenance and management is carried out, it in systems can Real-time Feedback Task Progress.
By software data acquisition interface channel, the data of acquisition are directly stored into type database, realization and third
Square information system is simple and direct rapidly to be integrated, and enterprise is helped to get rid of the management mode of information-based isolated island early.
And resulting information system structure is huge, with information-based development, data volume is also increased sharply therewith, scale
It is continuously increased with complexity, the concurrent data of magnanimity needs processing in real time, and is reliably stored, this deployment and peace to database
Full stabilization proposes new challenge.
For the purpose of calamity standby (Disaster Recovery), 2 (or multiple) data centers generally can be all built, one
A is that primary data center is used to undertake the business of user, one be Backup Data center be used to back up primary data center data,
Configuration, business etc.；Dual-active backup can be used as a kind of means that mass data reliably stores that solve, and dual-active is felt in preliminary data
The heart, which only backups, to be wasted very much, so allow active and standby Liang Ge data center all while undertaking the business of user, at this point, active and standby two number
It is mutually backups, and backs up in realtime according to center；In general, the load of primary data center may be more, for example divide
The business of load 60~70%, standby data center only share 40%~30% business.
Database resource pond based on Oracle12, which can be used as, solves a kind of deployment that the concurrent data of magnanimity is handled in real time
Means, wherein CDB and PDB is the new features that Oracle12C is introduced, in more rent user environments that ORACLE12C database introduces
In (Multitenant Environment), a database container (CDB) is allowed to carry multiple pluggable databases (PDB).
CDB full name is Container Database, and translator of Chinese is database container, and PDB full name is Pluggable Database,
I.e. pluggable database.Before ORACLE12C, example and database are one-to-one or many-to-one relationship (RAC): i.e. a reality
Example can only be associated with a database, and database can be loaded by multiple examples.And example and database are unlikely to be one
To more relationships.After entering ORACLE12C, example and database can be one-to-many relationship.
And how on the basis of guaranteeing the storage of intelligence manufacture data safety, more efficiently become using data-base cluster
One is worth solving the problems, such as.
