I try to make state online wiht below commands:

/bin/crsctl start res ora.eons << didnt work
srvctl start nodeapps  << didnt work

# ps -ef|grep eons  << doesnt return anything

I rised SR and here is the suggestion from Support:

Found bug 10139319 which suggests the problem could be due to shell limits not set high enough.

Ensure the shell limits are set correctly:

–> 2.10.5 Configuring Shell Limits

I checked and there is no issue with Sheel limit

Oracle support suggest below:

So we do have a few open bugs on showing java.io.EOFException, but no solution yet.
Also be aware that EONS no longer exists in so in case of an upgrade this problem will not be seen anymore.

I solved issue as reebot server. After reebot state has been changed.
