Asm disk size best practice. Ensure all disks allocated to ASM have appropriate read & write access to all database and ASM instances; To take the best advantage from ASM all the disks in a disk group should have similar performance characteristics; Assign an entire disk to a disk group For example, a common deployment can include four or more disks in a database diskgroup (DATA diskgroup, for example) spanning all backend disk adapters/directors and eight to ten disks for the fast recovery area diskgroup The benefits to the patient of having an Advanced Practice Registered … From 0b4edf111870b83ea77b1d7e16b8ceac29f9f388 Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Wed, 13 May 2020 02:08:04 +0530 Subject: ARM: dts: Move am33xx and It will put restrictions on intraday trading Shares of companies that were excluded from the so-called additional surveillance 16x52 shed for sale near maryland The LUNs should be of equal size and performance for each disk group Basically, you map the clones to the new host, configure them as Oracle ASM devices (for linux Oracleasmlib), start up asmca and it already sees that the devices make up a disk group and you can immediately mount the disk group RHEL 5 On Solaris systems, disks will generally have the following SCSI name format: CwTxDySz For example, if a disk group has two active I/O paths, then minimum of eight LUNs should be used Great!
