Instance management command: dsget returns discovery diskstringdsset settings discovery diskstringlsct displays the current oracle ASM client, generally refers to the database instance and ASM instance, the data comes from the V$ASM_CLIENT view lsop displays the current disk group or ASM instance operation, the data comes from the V$ASM_OPERATION view lspwusr displays the user orapwusr in the ASM password file increases, deletes Modify ASM password file user shutdown closes ASM instance startup starts ASM instance spbackup backup ASM SPFILE, does not affect GPnP profile Backup files are not recognized as SPFILE and cannot be copied with spcopy. In order to recognize that the backup file is SPFILE, you must use the cp command spcopy to copy ASM SPFILE, and you cannot copy more than one copy on the same disk group. To update GPnP profile, use the-u option or use the spset command spget to return the location of the ASM SPFILE to move the ASM SPFILE from the GPnP profilespmove and automatically update the GPnP profile. Cannot copy between two remote instances. Cp cannot be used for files of OCR and OCR backup types, but spbackup,spcopy,spmove. If it is a remote copy, the connection string style is: user@host [.port _ number] .Sid. Port_ number defaults to 1521du showing the disk space used in the specified directory (including subdirectories) find lookup, pay attention to case-sensitive ls display ASM directory contents lsof display local client opened files mkalias creates an alias for a system-generated file. Aliases and corresponding files must be on the same disk group and each ASM file can have only one alias mkdir create ASM directory pwd displays the path of the current directory rm deletes the specified file or directory, if it is an alias, it deletes the file corresponding to the alias and alias rmalias deletes the specified alias disk group management command chdg modifies the disk group (add disk, delete disk, resize disk Rebalance disk groups, based on XML profile) chkdg check or repair disk groups dropdg delete disk groups iostat displays disk IO statistics, information comes from V$ASM_DISK_IOSTAT view lsattr displays disk group properties, information comes from V$ASM_ATTRIBUTE view lsdg displays mounted disk groups and their information, like ls-ls output results, information comes from V$ASM_DISKGROUP_STAT view If-- discovery is specified, the query V$ASM_DISKGROUPlsdsk displays the ASM disk, with information from the V$ASM_DISK_STAT view Connection mode queries V$ASM_DISK_STAT and V$ASM_DISK return information; non-connection mode scans disk heads to return information lsod displays open devices md_backup creates mounted disk group metadata backup md_restore recovery disk group metadata backup mkdg creates disk groups based on XML configuration files.
