And did you attempt to put those errors into Google, or look them up in Oracle's knowledgebase? It's telling you very plainly that the file doesn't exist. So...either create it, modify the location, or restore it from backup:

yes,i googled it,the file was there and directory have permissions and selinux was also disabled,but some folders were missing in ORACLE_BASE and i created them,that solved my issue.Thank you so much for your reply......much appreciated.
