PRKH-1010 : Unable to Communicate With CRS Services During Listener Configuration 

After installing the Oracle Binaries for stand alone server when I tried to manually create the listener after Net configuration assistant failed during installation, I hit following error. 
Though it was surprising that it was showing error of CRS on stand alone server!!!

This was due to the bug with 11201 binaries which was causing this issue. 
[oracle@oem ~]$ cd /u01/app/oracle/product/11.0/db_1/bin/
[oracle@oem bin]$ ./netca
oracle.ops.mgmt.cluster.ClusterException: PRKH-1010 : Unable to communicate with CRS services.

Fix - 
This was due to ocr.loc file pointing to Shared device or ASM which is not hosted locally. 
so the ideas is to modify this behavior with local_only parameter set to TRUE.

[root@oem ~]# vi /etc/oracle/ocr.loc

ocrconfig_loc=+DATA

#local_only=FALSE
local_only=TRUE

Once this done, when you invoke the configuration assistance this time around it works fine...

[oracle@oem bin]$ ./netca
