12.1.0 Grid Installation on Solaris 11.3 fails with ASM failed to start


Issue Description

 We faced one issue, while installing the GI 12.1.0.1.0 on Solaris 11.3 


ASM failed to start. Check /u01/app/grid/cfgtoollogs/asmca/asmca-201202PM061908.log for details.


2020/12/02 18:19:17 CLSRSC-184: Configuration of ASM failed


2020/12/02 18:19:17 CLSRSC-258: Failed to configure and start ASM


Died at /u01/app/12.1.0/grid_1/crs/install/crsinstall.pm line 1976.

The command '/u01/app/12.1.0/grid_1/perl/bin/perl -I/u01/app/12.1.0/grid_1/perl/lib -I/u01/app/12.1.0/grid_1/crs/install /u01/app/12.1.0/grid_1/crs/install/rootcrs.pl ' execution failed

==================================================


Cause of the Error:

This is due to the known bug on 12.1.0 as per the Oracle Note. 2118379.1

The issue is addressed in unpublished
Bug 22500861 - CONSOLIDATE TXN FOR LARGE PAGESIZE SUPPORT OSM

The bug is fixed in 12.1.0.2.

As per bug report, the database start up failure was due to OSM (Optimized Shared Memory) segment. There were some transactions missing in 12.1.0.1 with respect to Solaris OS which leads to this failure. It will affect Solaris 11 latest updates.


SOLUTION

To solve the issue, use any of below alternatives:

  • Apply patch set 12.1.0.2

    - OR -

  • Apply interim patch 22500861, if available for your platform and Oracle version.

Cancel the GI installer, then apply the patch on both nodes
after the patches are successfully installed, perform the below steps to clean up and restart the configuration


1. cd $GI_HOME/crs/install/

./rootcrs.pl -deconfig -force 

Run this clean up on both nodes

2. Re-run the Configuration from vnc

cd /u01/app/12.1.0/grid_1/crs/config

./config.sh 


This will successfully complete the GI Installation
