• Article Type: General
• Product: Aleph
• Product Version: 18.01

Problem Symptoms:
In ALEPH logs there are the

ORA-00376: file dd cannot be read at this time

and

ORA-01110: data file dd: '/Exlibris /oradata/alephxx/alephxx_tsxx_0x.dbf'

error message.

Cause:
The Oracle data file is corrupted.

Resolution:
1. Login into Oracle like ALEPH_ADMIN
2. Execute the query: SELECT * FROM dba_data_files WHERE file_id =dd;
(dd is the file number listed in the Oracle error messages)
3. If the value of column ONLINE_STATUS is not ONLINE (probably it?ll be RECOVER) contact an Oracle DBA to try the data file recover.
