Oracle Database Appliance (ODA) is an entry level Engineered System. ODA is a pre-configured, highly available Oracle Database Engineered system. ODA system consists of hardware, software, storage and networking. The hardware configuration is designed to provide redundancy and protection against single points of failures in the system.

ODA consists of two physical servers (Node 0 and Node 1), a storage shelf and optionally an additional storage shelf. The two independent physical servers are interconnected and direct attached to SAS and SSD storage.

ODA is basically a 2-node RAC cluster database system running Oracle Linux operating (OEL), Oracle Database Enterprise Edition, Oracle Grid Infrastructure (Clusterware and ASM). All these together provides the Oracle Database high availability running on ODA.

ODA consists of several hardware components such as Mother Board, Processor, Memory, Power Supply, FAN, Network cards and so on. You can monitor the hardware status of these components using OAKCLI command for both Bare Metal and Virtualized platform.

Note: ODACLI is used for Hardware monitoring and administrative tasks on the Oracle Database Appliance on X6-2 S/M/L & X7-2 S/M.


In this article we will demonstrate how to monitor different hardware component status on ODA nodes.

Using OAKCLI command to Get Hardware Status

Using ILOM GUI to Get the Hardware Status




Conclusion

In this article we have learned how to monitor various hardware components status on ODA nodes using oakcli and ILOM. ODA server comes with different hardware components and monitoring them is key for ODA availability.

When Oracle ACS build Exadata Database Machine, they use the OEDA file that you sent them over for Exadata Install. The Exadata is built with default ASM Disk Group name DATAC1, RECOC1 & DBFS_DG. If you want to rename the DATAC1 and RECOC1 to something different to match your Organization standards you can do that by using the Oracle renamedg utility. The number Database version required to rename an ASM Disk Group is 11.2.

In this article we will demonstrate how to rename ASM Disk Group on Exadata Database Machine running Oracle Database 11.2

Here we want to change the following ASM Disk Group Names:
DATAC1 to DATA
RECOC1 to RECO

Steps to rename ASM Disk Group


  • Get the Database version

ORACLE_SID = [+ASM1] ? dbm011
The Oracle base remains unchanged with value /u01/app/oracle

  • Check the database status

[oracle@dm01db01 ~]$ srvctl status database -d dbm01

Instance dbm012 is running on node dm01db02
Instance dbm013 is running on node dm01db03
Instance dbm014 is running on node dm01db04

  • Make a note of the control files, Datafiles, Redo logfiles before stopping the database.

SQL> select name from v$controlfile;
SQL> select name from v$datafile;
SQL> select member from v$logfile;
SQL> select * from v$block_change_tracking;

  • Stop database database

[oracle@dm01db01 ~]$ srvctl stop database -d dbm01

[oracle@dm01db01 ~]$ srvctl status database -d dbm01

  • Umount the ASM disk group(s) that you want to rename. Connect to ASM command prompt and umount the disk group. umount the disk group from all nodes.

Conclusion

In this article we have learned how to rename an ASM Disk group on Exadata running Oracle Database 11.2. Starting with Oracle Database 11.2 you can use the renamedg command to rename an ASM Disk Group. renamedg utility cannot rename the associated ASM/Grid disk disk name. Also renamedg cannot rename/update the control files, datafiles, redo log files and any other files that reference ASM DG for all databases. You must update database files manually after renaming ASM disk groups.
