Directory/Executable/File Purpose

/opt/oracle.cellos/iso Contains kernel ISO images

/opt/oracle.cellos/make_cellboot_usb.sh Creates a USB rescue image

/opt/oracle.cellos/MegaCli64 MegaCLI —also in /opt/MegaRAID/MegaCli

/opt/oracle.cellos/patch Directory for staged patches

/opt/oracle.cellos/restore_cellboot.sh

Restores from USB rescue image

/opt/oracle.cellos/validations_cell Directory containing output from cell server validations

/opt/oracle.cellos/vldconfig Configures cell validation

/opt/oracle.cellos/vldrun Runs cell validation scripts and logs to /opt/oracle.cellos/

validations_cellw

/opt/oracle/cell Symlink to /opt/oracle.cell[VERSION]

/opt/oracle/cell[VERSION] Directory containing current cell software. For example,

/opt/oracle/cell11.2.2.4.2_LINUX.X64_111221

/opt/oracle/cell[VERSION]/cellsrv Directory containing cellsrv software

/opt/oracle/cell[VERSION]/cellsrv/deploy/
config

Configuration deployment files for active cell image

/opt/oracle/cell[VERSION]/cellsrv/deploy/
config/cellinit.ora

Cell initialization parameter file

/var/log/oracle Directory containing cell server log files, alerts, and trace files

/var/log/oracle/cellos Directory containing log and trace files for Cell Services

utilities, validation framework, and cell server startup/
shutdown events

/var/log/oracle/diag/asm Directory containing log and trace files for cell

storage-related events in your cell

How It Works
Each Exadata storage cell is installed with its Cell Services software, configuration files, diagnostics utilities, and
log/trace file directories in the same locations. At a high level:

• Cell Services software and diagnostics utilities are installed in /opt/oracle.cellos;

/opt/oracle/cell[VERSION] , where VERSION is

• Cell Services configuration files are located in

the current image version of your cell;

• Cell server log files, trace files, and alerts are stored in assorted directories under

/var/log/oracle .
