asm commands in oracle 11g

I. The following error is reported when 10gRAC uses DBCA to reconstruct asm:The ASM instance configured on the local node is a single-instance ASM. to create a single-instance database using this ASM instance, restart DBCA and select the single-instance database option, to create a RAC database using this ASM instance,

Oracle 11gR2 uses gpnp profile to store the spfile path of ASM Since Oracle 11gR2, GI has integrated ASM, and OCR/VOTEDISK has also been stored in the ASM disk group (which must be stored on bare devices before 11gR2 ), at the same time, the functions of

when one disk is added to the disk group and the other disk is just invalidated.ASM compatibility Specifies the minimum ASM software number for the mounted disk group. Oracle Database 10g Products This field always uses 10.1. When the Compatible.asm property is upgraded to 11.1,asm to save the version number in the PST, update the disk header in the disk group t

If the database uses the ASM file system for management, it may be difficult to download and upload files. Even if the asmcmd tool is used, there is no command similar to CP to copy files, oracle provides FTP to manage a series of ASM files. Using FTP with Oracle ASM filesht

In a production environment, DBAs tend to face dozens of of hundreds of g of data, or even the T-level, file system storage data files in these situations, I/O problems will gradually exposed, so the data storage in the production environment generally use ASM, or bare devices, Oracle 11G does not support raw devices to store data at the beginning, so this talk m

devices will no longer be supported in Oracle12. Oracle strongly recommends using at least 3 voting disks in a different location. When using ASM to manage voting disks, you need to be aware of the redundancy levels of disk groups and failure groups. Note that all copies of voting disk are in one disk group, and you cannot distribute voting disks across multiple disk groups. When using an externally redund

How to Use udev for Oracle ASM in Oracle Linux 6 Original article: http://www.dbform.com/html/2011/1708.html Most of the documents available on the Internet are set up with udev in rhel5 or oel5. udev is most useful for Linux to prevent the disk used as an ASM disk from changing after the operating system is restarted.

data files are stored in this shared store. There are some storage methods such as OCFS, OCFS2, RAW, NFS, ASM, and so on. The OCFS (Oracle Cluster file system) and OCFS2 are just a filesystem, and, like NFS, they provide a shared storage file system in a clustered environment. Raw bare devices are also a way of storage that is supported by RAC in previous versions of oracle11g, and before oralce9i, Ops/rac
