Red Hat 6 and Oracle, status of certification

Red Hat 6 has been there a while, so what about certification with Oracle and when? Nothing yet on the Oracle support site, no press releases (maybe I missed one..). But Red Hat had a blog-post about it a while ago (august 2011):

We’re pleased to announce that on Tuesday, August 9, we formally submitted to Oracle full certification test results of the Oracle 11gR2 database (Single Instance and RAC (including ASM) for x86 and x86-64) on Red Hat Enterprise Linux 6. Oracle database certification is a self-certification program whereby operating system vendors perform extensive testing and submit the results to Oracle for audit and approval.

Errors in alert log [NI cryptographic checksum mismatch] TNS-12599

Using rdbms 11.2 as the repository for our Grid Control environmont, noticed a lot of the same errors in the alert file of the repository or/and the target database:

NI cryptographic checksum mismatch error: 12599.
VERSION INFORMATION:
TNS for Linux: Version 11.2.0.2.0 – Production
Oracle Bequeath NT Protocol Adapter for Linux: Version 11.2.0.2.0 – Production
TCP/IP NT Protocol Adapter for Linux: Version 11.2.0.2.0 – Production
Time: 24-MAR-2011 11:58:31
Tracing not turned on.
Tns error struct:
ns main err code: 12599

TNS-12599: TNS:cryptographic checksum mismatch
ns secondary err code: 2526
nt main err code: 0
nt secondary err code: 0
nt OS err code: 0

Note: 1150874.1 gives the cause, workaround and solution:

Restoring OCR on 11.2.0.2-cluster

As the documentation about restoring an OCR did not work as it should be, the following has been succesfully tested…

Log on as “root”
# . oraenv +ASM1
# ./ocrconfig -showbackup
# ./ocrconfig -showbackup manual

Stop the cluster on all nodes

# crsctl stop crs

My RAC project with Openfiler, part II – grid infrastructure and database

This is the second post of my little project of building my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) :

  • 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database.
  • 1 VM as my own SAN, based on Openfiler 2.3 (free), for ASM.

My goal: just a little bit hands-on experience with Openfiler, and do some testing with RAC 11gr2, and especially 11.2.0.2. Maybe it’s helpful for somebody else, so I’ll post my experiences. Steps I’m gonna perform.

-          The first post handled the following:

1.       Planning my installation
2.       Create a VM with OpenFiler
3.       Configure Openfiler

-          The second post (this post):

4.       Create a VM as node rac1 and configure ASM
5.       Create a VM as node rac2
6.       Install Oracle RAC Infrastructure
7.       Install Oracle RAC software

8.       Install Oracle RAC database

My RAC project with Openfiler, part I – Openfiler

My current job doesn’t offer me at the moment the opportunity to play with RAC or other stuff, so I decided to build my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) :

  • 2 VM’s (VMware, not OracleVM!) for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra and database.
  • 1 VM as my own storage, based on Openfiler 2.3 (free) and ASM as storage manager.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Powered by rPath Linux, Openfiler is a free browser-based network storage management utility that delivers file-based Network Attached Storage (NAS) and block-based Storage Area Networking (SAN) in a single framework. Openfiler supports CIFS, NFS, HTTP/DAV, FTP, however, we will only be making use of its iSCSI capabilities to implement an inexpensive SAN for the shared storage components required by Oracle RAC 11g. A 500GB internal hard drive will be connected to the network storage server (sometimes referred to in this article as the Openfiler server) through an internal embedded SATA II controller. The Openfiler server will be configured to use this disk for iSCSI based storage and will be used in our Oracle RAC 11g configuration to store the shared files required by Oracle Clusterware as well as all Oracle ASM volumes.
