2.1.2.6 Validating Expansion of Oracle Exadata Database Machine
After expansion, validate the new configuration.
Note:
This procedure applies only to the original storage servers in the following Oracle Exadata Database Machine Eighth Rack models: X4-2, X5-2, X6-2 with Extreme Flash (EF) storage servers.
This procedure does not apply where hardware resources are expanded by adding more servers.
-
Log in as the
root
user on the first database server. -
Check the database server core count using the following command:
# dcli -g db_group -l root 'dbmcli -e list dbserver attributes coreCount'
-
Review the database server configuration using the following command.
# dcli -g db_group -l root 'dbmcli -e list dbserver attributes eighthrack'
The output should show
FALSE
. -
Review the storage server configuration using the following command.
# dcli -g cell_group -l celladmin 'cellcli -e list cell attributes eighthrack'
The output should show
FALSE
. -
Review the appliance mode for each disk group using the following commands:
SQL> set lines 100 SQL> column attribute format a20 SQL> column value format a20 SQL> column diskgroup format a20 SQL> SELECT att.name attribute, upper(att.value) value, dg.name diskgroup \ FROM V$ASM_ATTRIBUTE att, V$ASM_DISKGROUP DG \ WHERE DG.group_number = att.group_number AND \ att.name LIKE '%appliance.mode%' ORDER BY DG.group_number;
-
Validate the number of Oracle ASM disks using the following command:
SQL> SELECT g.name,d.failgroup,d.mode_status,count(*) \ FROM v$asm_diskgroup g, v$asm_disk d \ WHERE d.group_number=g.group_number \ GROUP BY g.name,d.failgroup,d.mode_status; NAME FAILGROUP MODE_ST COUNT(*) ------------------------- ----------------------------- ------- ---------- DATAC1 EXA01CELADM01 ONLINE 12 DATAC1 EXA01CELADM02 ONLINE 12 DATAC1 EXA01CELADM03 ONLINE 12 RECOC1 EXA01CELADM01 ONLINE 12 RECOC1 EXA01CELADM02 ONLINE 12 RECOC1 EXA01CELADM03 ONLINE 12 RECOC2 EXA01CELADM01 ONLINE 12 RECOC2 EXA01CELADM02 ONLINE 12 RECOC2 EXA01CELADM03 ONLINE 12 DBFS_DG EXA01CELADM01 ONLINE 10 DBFS_DG EXA01CELADM02 ONLINE 10 DBFS_DG EXA01CELADM03 ONLINE 10
Each High Capacity (HC) storage server (non-Eighth Rack) contains 12 disks.
