Yesterday Yuva Kishore is commented on my Oracleasm - Instantiating disk : failed post and asked a question: We can list the asm disks (listdisks) but where can we find the mapping that ASMDISK1 is mapped to /dev/sda1 and so on?
I want answer this question with this post.
If you are using ASMLib for configure ASM Disks, then you can use following steps for define which device mapped which ASM Disk.
As you know, oracleasm listdisks is return only ASM disk names
[grid@oel62-rac1 ~]$ oracleasm listdisks
If you want find which ASM disk is mapped which device, then you must use oracleasm querydisk with ASM disk name.
[grid@oel62-rac1 ~]$ oracleasm querydisk -d ASMDISK01
Disk "ASMDISK01" Is a valid ASM disk On device[8,17]
As see you, ASMDISK01 is valid ASM disk on device [8,17].
What is means? It means ASMDISK01 is mapped to device [8,17].
How to find [8,17] device? We must use Linux ls –l c…
Oracle Technology Network Latina started publish our new article series about Oracle Database In-Memory. This articles is first about In-Memory in OTN Latina articles.

Oracle Database 18c was available on Oracle Cloud. Now everybody can download Oracle Database 18c On-Premises for Linux (LINUX.X64_180000_db_home.zip) Oracle change a little on installation file. OUI does not copy files to Oracle Home
You just extract the zip file to Oracle Home directly and OUI only linking binaries.
I installed Oracle Database 18c on Linux 7.1. Before installation, I set Oracle environments such as (ORACLE_HOME, ORACLE_BASE). You can add these settings in oracle user .bash_profile.
