This document provides a procedure to configure/reconfigure the ( High Availability Service ) HAS and CSS resource on Oracle Grid Infrastructure for nonRAC setup
Solution
1） When you install grid infrastructure for single instance, at the end we run root.sh, that directs you to run the following script from root login:
<GridHome>/perl/bin/perl -I<GridHome>/perl/lib -I<GridHome>/crs/install <GridHome>/crs/install/roothas.pl
This script configures the ohasd daemon ( inittab and rc.d entries ) and start the followings:
# ps -ef|grep ohas root 17162 1 0 17:05 ? 00:00:00 /bin/sh /etc/init.d/init.ohasd run grid 17186 1 0 17:05 ? 00:00:00 /oracle/grid/bin/ohasd.bin reboot
If there is a need to reconfigure HAS then, we can run the following scripts from root login:
<GridHome>/perl/bin/perl -I<GridHome>/perl/lib -I<GridHome>/crs/install <GridHome>/crs/install/roothas.pl -delete <GridHome>/perl/bin/perl -I<GridHome>/perl/lib -I<GridHome>/crs/install <GridHome>/crs/install/roothas.pl
Note that the "roothas.pl -delete" will stop the cssd and diskmon resources ( and their dependent resources like ASM, Diskgroup, RDBMS ) and then will deconfigure HAS.

If there is a malformed crs installation and CRS is not runing, one need to run rootcrs.pl and roothas.pl -deconfig with force options as follows:
<GridHome>/perl/bin/perl -I<GridHome>/perl/lib -I<GridHome>/crs/install <GridHome>/crs/install/roothas.pl -deconfig -force
<GridHome>/perl/bin/perl -I<GridHome>/perl/lib -I<GridHome>/crs/install <GridHome>/crs/install/roothas.pl -delete -force
<GridHome>/perl/bin/perl -I<GridHome>/perl/lib -I<GridHome>/crs/install <GridHome>/crs/install/roothas.pl
We can also stop/start, disable_auto_start/enable the HAS we use the following commands:
# cd <Grid Home>/bin # ./crsctl stop has # ./crsctl start has # ./crsctl disable has # ./crsctl enable has
Here also the ora.cssd and ora.diskmon dependency on HAS is maintained. You can also use -d option with the perl script run, in case you wish to debug the script ( perl expertise is needed ).
2） Unlike 10.2 / 11.1, CSS and Diskmon processes are resources in the OCR now.
$ crsctl status resource -t -------------------------------------------------------------- NAME TARGET STATE SERVER STATE_DETAILS -------------------------------------------------------------- Cluster Resources ------------------ ora.cssd 1 ONLINE ONLINE db112 ora.diskmon 1 ONLINE ONLINE db112
Daemons no more run from ../init.d scripts:
grid 26182 1 0 20:11 ? 00:00:00 /oracle/grid/bin/diskmon.bin -d -f grid 26091 1 0 20:09 ? 00:00:00 /oracle/grid/bin/cssdagent grid 26126 1 0 20:09 ? 00:00:00 /oracle/grid/bin/ocssd.bin
The following commands should NOT be used to remove/add the CSS resource from OCR
#./crsctl delete resource ora.cssd #./crsctl add resource ora.cssd -type
Instead use the delete and add commands of HAS to delete/add CSS/Diskmon.
