About the Storage Volumes Attached to the WebLogic Server Nodes

You can connect using ssh to all the compute nodes of an instance and access the attached storage volumes. To ensure that the instance remains manageable, you must treat some volumes as read-only disks.

The following table maps the volumes that are attached to a WebLogic Server node and the corresponding mount points:

Mount Point	Content	Volume
/ and /boot	Operating system binaries	boot
/dev/shm	Swap space	boot
/u01/data/backup	Backups, if configured (writable by the oracle user; the opc user has read-only access)	backup
/u01/data/domains	WebLogic Server domain data (DOMAIN_HOME) Deployed applications and configuration files (APPLICATION_HOME)	domain
/u01/app/oracle/middleware	Oracle WebLogic Server binaries and Oracle Traffic Director binaries (MW_HOME) (treat as read-only)	common
/u01/app/oracle/tools Caution: Don’t modify any scripts in this directory.	Binaries and related metadata required for service management (JCS_RESERVED) (treat as read-only)	common
/u01/jdk	JDK binaries (JDK_HOME) (treat as read-only)	common
