Hi,
We recently had a site failure post which we faced oracle database issues in most of our systems. There was a storage failure also. We have recovered our ECC Prd system using tape backup and are now working on dev and qas systems.
We are facing a common error in two three systems in which we are unable to even mount a database. Lisyener is running sucessfully.
When we give a startup command we get the following error :
SQL> startup
ORA-24324: service handle not initialized
ORA-01041: internal error. hostdef extension doesn't exist
SQL>
Also we get an error as below if we give a startup command :
SQL> startup mount
ORACLE instance started.

There is no update in alert log and well as user trace.
May kindly suggest some way to troubleshoot please.
