Introducing Oracle AFD Before Oracle grid infrastructure 12c, the only method to access ASM disks was ASLIB. With the start of GI 12c (12.1.0.2), Oracle Introduced Oracle AFD (ASM Filter Driver). Oracle AFD has been come to cover weaknesses of the ASMLIB. You could find some of the benefits using AFD (ASM Filter Driver) as below: Rejection of non-Oracle I/Os. Oracle Automatic Storage Management Filter Driver (Oracle AFD) rejects write I/O requests that are not issued by Oracle software. This filter …
Two of the best key features of the multitenant container databases are unplugging PDB from CDB and plugging PDB to the same or another CDB respectively. Let me explain how the unplugging actually works: There are two methods for unplugging PDB from CDB. The first and the older method which has been introduced in Oracle database 12.1 is unplugging PDB from the XML description file and the newer method that has been introduced in Oracle database 12.2 is unplugging PDB …
