The various types of storage in a computer are volatile storage, nonvolatile storage, and stable storage Data in volatile storage, such as in RAM, are lost when the computer crashes Data in nonvolatile storage, such as disk, are not lost when the computer crashes, but may occasionally be lost because of failures such as disk crashes Data in stable storage are never lost Stable storage that must be accessible online is approximated with mirrored disks, or other forms of RAID, which provide redundant data storage Of ine, or archival, stable storage may consist of multiple tape copies of data stored in a physically secure location In case of failure, the state of the database system may no longer be consistent; that is, it may not re ect a state of the world that the database is supposed to capture To preserve consistency, we require that each transaction be atomic It is the responsibility of the recovery scheme to ensure the atomicity and durability property There are basically two different approaches for ensuring atomicity: log-based schemes and shadow paging In log-based schemes, all updates are recorded on a log, which must be kept in stable storage In the deferred-modi cations scheme, during the execution of a transaction, all the write operations are deferred until the transaction partially commits, at which time the system uses the information on the log associated with the transaction in executing the deferred writes In the immediate-modi cations scheme, the system applies all updates directly to the database If a crash occurs, the system uses the information in the log in restoring the state of the system to a previous consistent state To reduce the overhead of searching the log and redoing transactions, we can use the checkpointing technique In shadow paging, two page tables are maintained during the life of a transaction: the current page table and the shadow page table When the transaction starts, both page tables are identical The shadow page table and pages it points to are never changed during the duration of the transaction When the transaction partially commits, the shadow page table is discarded, and the current table becomes the new page table If the transaction aborts, the current page table is simply discarded If multiple transactions are allowed to execute concurrently, then the shadowpaging technique is not applicable, but the log-based technique can be used No transaction can be allowed to update a data item that has already been updated by an incomplete transaction We can use strict two-phase locking to ensure this condition Transaction processing is based on a storage model in which main memory holds a log buffer, a database buffer, and a system buffer The system buffer holds pages of system object code and local work areas of transactions. how to write byte array to pdf in java: Java: convert a file to a byte array, then convert byte array to a file. java write pdf file to response Read and generate pdf in Java- iText Tutorial - HowToDoInJava
