問題4: Your customer wants you to partition the database and storage grids in his X3-2 fiull rack,
creating database clusters and two storage grids.
One cluster will be used fior production and should consist ofi 6 databases servers and 11 cells firom
the first storage grid.
The other cluster will be used fior test and development, and should consist ofi 2 database servers
and 3 cells firom the second storage grid.
The storage must be partitioned so that the cells are visible only to the appropriate database servers
based on the description above.
What must be done to achieve this?
A. Configure Exadata realms using Oracle ASM scoped security mode.
B. Configure Exadata realms using Database scoped security mode.
C. Edit the CELLIP.ORA file on each database server to contain IP addresses ofi cells in the storage grid
associated with cluster to which that database server belongs.
D. Edit the CELLINIT.ORA file on each database server to contain IP addresses ofi cells in the storage
grid associated with the cluster to which that database server belongs.
E. Edit the CELLIP.ORA file on each database server to contain IP addresses ofi database servers which
are allowed access to specific cells in the same storage grid.
F. Edit the CELLIP.ORA file on each cell to contain IP addresses ofi database servers in the database
server grid that are associated with the storage grid to which that cell belongs.
正解: C
Explanation:
cellip.ora
The cellip.ora is the configuration file, on every compute node, that tells ASM instances which cells
are available to
this cluster.
Here is a content ofi a typical cellip.ora file fior a quarter rack system:
$ cat /etc/oracle/cell/network-config/cellip.ora
cell="192.168.10.3"
cell="192.168.10.4"
cell="192.168.10.5"
Now that we see what is in the cellip.ora, the grid disk path, in the examples above, should make
more sense.
Note:
* cellinit.ora decides which network takes storage traffic.
* cellip.ora - list ofi cells, new cells can be added dynamically without shutdown
