java.lang nullpointerexception While Installing 12.1.0.2 RAC Database Software

Mon, 2016-04-18 03:41

RSS content

I have an Oracle  12.1.0.2c cluster having following 5 nodes :

  • Hub Nodes : host01, host02, host03
  • Leaf nodes: host04 and host05

I wanted to install RAC database software on the 3 hub nodes i.e. host01, host02 and host03.

I invoked the OUI as oracle user (Owner of Database Home)

[oracle@host01 database_12_1_0_2]$ ./runInstaller

and chose the option to install RAC database software only on the 3 hub nodes.

After all the pre-requisite checks were successful , I clicked the Install button.
I got the error: java.lang nullpointerexception

On clicking OK, the OUI aborted.

To troubleshoot, I ran the OUI in debug mode as :

[oracle@host01 database_12_1_0_2]$ ./runInstaller -debug -J-DTRACING.ENABLED=true -J-DTRACING.LEVEL=2 -J-DSRVM_TRACE_LEVEL=2 -J-DFULLTRACE

The trace file showed that the leaf node host05 was not responding:

[setup.flowWorker] [ 2016-04-18 14:33:22.771 IST ]
[CRSCTLUtil.getClusterNodeConfigRoles:1198] outputs[4] = CRS-4404: The following nodes did not reply within the allotted time:
[setup.flowWorker] [ 2016-04-18 14:33:22.772 IST ]
[CRSCTLUtil.getClusterNodeConfigRoles:1200] values length = 2
[setup.flowWorker] [ 2016-04-18 14:33:22.772 IST ]
[CRSCTLUtil.getClusterNodeConfigRoles:1198] outputs[5] = host05
[setup.flowWorker] [ 2016-04-18 14:33:22.772 IST ]
[CRSCTLUtil.getClusterNodeConfigRoles:1200] values length = 1

I realized that although I wanted to install database software on 3 nodes only, all the nodes
needed to be up and running whereas in my case, the node host05 was down at that time.

When I started the node host05 and reinvoked OUI, the database software was installed
successfully.

It gives me immense pleasure to share the news that I have been honored with the prestigious  Oracle ACE award. I am grateful to Oracle ACE Program for accepting my nomination. I would like to thank to Murali Vallath Sir who nominated me for this award. I am also thankful to my family members without whose support and motivation, this would not have been possible.  Thanks a lot to all the readers of my blog whose comments and suggestions helped me to learn and share whatever little knowledge I have.

I will do my best to participate in the Oracle ACE program.

I Am Speaking at OTN Yathra 2016

The Oracle ACE directors and Oracle Volunteers  in the region are organizing their third evangelist event called ‘OTNYathra 2016’ from 23rd  April 2016 to 1st May 2016.  This yathra or tour will a series of 6 conferences across 6 major cities (Chennai, Bangalore, Hyderabad,  Pune, Mumbai and Delhi) managed by ACE directors and Oracle Volunteers of the region.

I will be speaking at this year’s OTNYathra  about Oracle Database 12c new feature : Highly Available NFS (HANFS) over ACFS.

HANFS over ACFS enables highly available NFS servers to be configured using Oracle ACFS clusters. The NFS exports are exposed through Highly Available VIPs (HAVIPs), and this allows Oracle’s Clusterware agents to ensure that HAVIPs and NFS exports are always available. If the node hosting the export(s) fails, the corresponding HAVIP and hence its corresponding NFS export(s) will automatically fail over to one of the surviving nodes so that the NFS client continues to receive uninterrupted service of NFS exported paths.

My session will be held on Sunday 1st May, 2016   from 3:00pm to 3:50pm in
Room 1, BirlaSoft, H–9, Sector 63, NOIDA – 201306, NCR Delhi
Hope to meet you there!!

One Million Page Views

Fri, 2016-02-26 02:06

RSS content

Yesterday page views of  my blog touched the magical figure of 1 Million.  I had started blogging in November 2012 with the aim of saving whatever I learn, on the web in a language simple enough to be understood by even a beginner. Well, I myself was a beginner then and even now I am a beginner.  I think I am a bit skeptical – not easily convinced until I get a proof. So, in most of my posts , I try to verify the facts mentioned in oracle documentation and I presume that’s what has clicked with the readers of my blog.

I would like to thank all the readers of my blog  who spent their precious time in going through my posts and giving their valuable feedback.

Keep visiting my blog…
