Which three statements are true about an Oracle Database RAC software installation? (Choose three.)
A.
The software must be installed into a cluster file system.
B.
The software must be installed into a local file system on each node.
C.
RAC installations require Oracle Enterprise Edition.
D.
Fix-up scripts generated during the installation must be run as root on UNIX platforms.
E.
The software can be installed into an ACFS file system.
F.
The software must be installed on all nodes in the cluster.
G.
SSH user equivalence for the Oracle user can be set up before the software installation.
Correct: D, E, G
Wrong A – software CAN be installed into CFS
Wrong B – Oracle Database on Hub Nodes for Oracle Database 11g Release 2 (11.2) and later CAN be installed at CFS
Wrong C – Oracle “baby rac” works at SE2
Wrong F (e.g. application node in CRS)
D – documentation says, that fixup scripts from GI must be run from root user. Nothing about fixscripts in RDBMS instalation (During installation, for certain prerequisite check failures, you can click Fix & Check Again to generate a fixup script (runfixup.sh). You are then prompted by OUI to run the fixup script as the root user in a separate session. You must run the script on all the nodes specified by OUI)
BUT The Fixup script does the following tasks:
Shared memory parameters.
Open file descriptor and UDP send/receive parameters.
Creates and sets permissions on the Oracle Inventory (central inventory) directory.
Creates or reconfigures primary and secondary group memberships for the installation owner, if necessary, for the Oracle Inventory directory and the operating system privileges groups.
Sets shell limits if necessary to required values.
All of these tasks needs root
E – Oracle Database on Hub Nodes for Oracle Database 11g Release 2 (11.2) and later CAN be installed at CFS, except at leaf nodes
Agree D,E,G
and about the “baby rac” haha was fun
