ORACLE locks have the following modes:0: none1: null2: Row-S Row sharing (RS): Share table lock3: Row-X (RX): used for Row Modification4: Share lock (S): blocks other DML operations5: S/Row-X dedicated shared rows (SRX): block other transaction operations6: exclusive dedicated (X): used for independent access The larger the number, the higher the lock level, the more operations affected.Level 1 locks include Select, which sometimes appears in v $ lock

locks-null (N), row share (RS), row exclusive (RX), share lock (s), share row exclusive (SRx ), or exclusive (X ). GRD (Global Resource dictionary)Global Resource Directory, jointly maintained by GCS and GES (can be considered as a memory database), stores the block information in the current cache (data block address, instance of the latest version, mode, role, SCN, pi ). GRD records the location of the latest database, block mode and role. All reso

device number SD indicates that the SCSI disk,a represents the first SCSI device. If there is a second SCSI device, then the corresponding device file is/dev/sdb. x represents the corresponding partition number for the SCSI device. For example,/DEV/SDA1 represents the first partition of the first SCSI device.4. Optical driveIDE CD-ROM the corresponding device file for Linux system is/dev/had, which indicates the IDE CD-ROM of the first IDE port (Master), and the SCSI CD-ROM corresponding device

number SD is the SCSI disk abbreviation, a indicates the first SCSI device, and x represents the corresponding partition number of the SCSI device.The CD-ROM drive has an IDE and SCSI interface, where the IDE CD-ROM corresponds to a device file of/dev/hda, which indicates the first IDE port (Master), and the SCSI optical drive corresponding to the device file/dev/srx,x represents the SCSI ID. Many versions also have a CDROM device file under/dev, in

Any transaction t in a multi-granularity blocking method with intent lock to lock a database object, it must first add an intent lock to its upper node. The application of the blockade should be carried out in a top-down order, and the release of the blockade should be carried out in a bottom-up order; a multi-granularity blocking method with intent lock improves the system concurrency and reduces the overhead of

categories of scientific literature, health, genomics, genetics, proteins and chemicals. Each database has its own minimum publishing unit. For example, the PubMed is an article, whereas in SRA, the smallest unit of release is an experiment (logged in as srx#). The SRA experiment consists of sequence data and how the biological sample is sequenced (meta data). The SRA database interacts with other databasesAll NCBI databases are inter
