ORA-00372: file cannot be modified at this time

You notice that you have following errors in SAP R/3, Database Alert.log file, or BR*Tools log:

ORA-00372: file cannot be modified at this time

Short dump: ABAP runtime error DBIF_RSQL_SQL_ERROR
                     SQL error 372 occurred in statement

ORA-00372: file xx cannot be modified at this time
ORA-01110: data file xx: <data file full path>
BR0324W Insertion of database log header failed

Firstly please check and follow note 328785 – ORA-00376: File cannot be read at this time.

If after you executed the calls in steps 2, 4, and 6 of note 328785, they do not return any lines. But you still have the problem. This is caused by tablespace is with status READ ONLY. In this mode, you can not modify the data files under this tablespace.

Please carry out following steps:

1. Start SQLPLUS:
sqlplus “/as sysdba”

2. Check whether tablespaces are set READ ONLY (now the database is in OPEN state):

3. If tablespaces are returned, reset them to ONLINE:

4. If the call in step 2 does not return lines anymore, the problem is corrected.

      Hi Ginny Guo,
      your entry was very helpful.
      Unfortunately note 328785 – ORA-00376: File cannot be read at this time
      wasn't complete to solve the problem.

      I've got the errorORA-00372: file 17 cannot be modified at this time
      after DBUA - Oracle Upgrade from 11g to 12c. So I guess DBUA didn't work correct. The tool set the tablespaces as suggested in mode "read only" but (in only one case ) not back to "read write".
      SAP started but Login wasn't possible. The message "SQL error in the database when accessing a" was all I've got.
      Thanks very much for solving this problem.
      Many Regards,
