the Normal-redundancy Disk group has a PST. The High-redundancy disk group has 5 PST if there are enough failure groups present. However, each defunct group in the High-redundancy Disk group has a PST.PST is a shadow paging used to ensure that the active PST on disk is always consistent, in time PST across multiple blocks. AU 1 satisfies the need to write two parts of PST. One is an active copy, and the other copies are used for PST updates. Once the PST is updated, the previous shadow becomes

judge based on the parameter file category, but based on this keyword. If the initialization parameter file is correct, a keyword error may mislead the database to start the process, resulting in a database startup error. Considerations for modifying Oracle Database initialization parameters If the initialization parameter file is not specified when the command startup is used to start the database (for example, the database is automatically started

First, specify the parameter file when the database is started. In the process of starting a database, you must provide an accurate initialization parameter file, whether it is a text parameter file or a server parameter file. When you start a database by using the startup command, you can specify the server parameter file that it takes. However, there is a need to pay attention to a detail, that is, the use of initialization parameter files, the use of the keyword is different. If you are usin

CHAPTER ASM Persistent Data structuresAs with traditional file systems and volume managers, ASM storage metadata is used to describe and track the contents of a disk group. All metadata describes the composition and content of the ASM disk group stored above, which enables the disk group to be self-describing. ASM Disk groups have two types of metadata: physical metadata and virtual meta data. Physical meta
