By Mouhamadou Diaw<\/strong><\/p>\n

In this blog we are going to install an Oracle Restart 19c with ASM Filter Driver (AFD). I am using following configuration
\n-Oracle 19c
\n-Oracle Linux Server 7.6
\n-Kernel 4.14.35-1902.2.0.el7uek.x86_64<\/p>\n

Once the Oracle Restart installed, I will create an ACFS filesystem<\/p>\n

We will have to configure following disks for AFD
\n-\/dev\/sdc
\n-\/dev\/sdd<\/p>\n

The Oracle downloaded software was unzipped to the GRID_HOME<\/p>\n

[oracle@oraadserver u01]$ unzip -d <\/code>\/u01\/app\/19<\/code>.0.0.0<\/code>\/grid<\/code> LINUX.X64_193000_grid_home.zip<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

After setting the variables ORACLE_HOME and ORACLE_BASE, we then use with user root the command asmcmd afd_label to provision disk devices for use with Oracle ASM Filter Driver.<\/p>\n

We can verify the status of the disks with the command afd_lslbl<\/p>\n

In my case with the kernel 4.14.35-1902.2.0.el7uek.x86_64, I had to apply the following

Now using asmca, let\u2019s configure an ACFS filesystem . Basically we
\n-Create a CRS diskgroup
\n-In CRS diskgroup we create a volume
\n-In this volume we create an ACFS filesystem and mount it<\/p>\n

It was strange to manually mount the ACFS filesystem at system reboot but it is mentioned in Oracle documentation
\nStarting with Oracle Database 12c, Oracle Restart configurations do not support the Oracle ACFS registry.<\/em>
\nThis means that the Oracle ACFS file system resource is supported only for Oracle Grid Infrastructure cluster configurations; it is not supported for Oracle Restart configurations. When using ACFS on Oracle Restart, we have to mount the filesystem manually mount and umount the ACFS filesystem<\/p>\n

Conclusion<\/h3>\n

When using ACFS with Oracle Restart, we have to manually mount and umount the ACFS filesystem when the system stops or starts. This can be done by some customized scripts.<\/p>\n","protected":false},"excerpt":{"rendered":"
