Overview
- CRS mamnaged ACFS is designed for creating a shared ORACLE_HOME file systems
- You cannot store Oracle database files amd Grid Infrastructure Home files in ACFS
- Registery Managed ACFS can used to store following datatypes: BFILE, exports , ADR , .

Thanks for sharing such rich information on ACFS

Thank you so much for a great article. I need to set up ACFS replication on a single node for DR purposes. I read it can be done on a 1-node cluster. Would I use the RAC ONE NODE software for this or the Grid Infrastructure software. I understand Oracle Restart is not supported and I cannot get the cluster install to complete with just one NIC. Your direction would be greatly appreciated. Thank you
