Comment on Cannot log via SQL plus on server : ORA 03113 by mrsmwiti

True its a Windows machine but that account is the one we log in to the server with. I have altered SQLNET.ORA and it worked. I am able to log in now. Just wonder if this problem signifies another underlying issue…

Thanks for your question.
1. I believe it is windows machine and it could happen because the user account you logged in is not the one you have used earlier.
2. Check SQLNET.ORA and TNSNAMES.ORA of working and not working work stations.

Comment on ORA-01122: database file xxx failed verification check by mudhalvan

The above explained syntax went well and database is opened. I have used the NORESETLOGS but when using shutdown immediate i am getting following error.

SQL> shutdown immediate
ORA-00607: Internal error occurred while making a change to a data block
ORA-00600: internal error code, arguments: [4193], [6179], [6757], [], [], [],
[], []

and database process get killed automatically.

After check the document I understand it is because of inconsistent backup method so i should have went with RESETLOGS option.

Comment on How to execute a shell script from an Oracle trigger by mudhalvan

Hi Sai,
Step 6 is required to exeute the script from any location because ORALCE_HOME/bin is already added in the PATH environment variable. If you would like to go the folder and execute everytime then you can ignore step6.

Hi there, is step 6 necessary? In other words, can I keep the script in a separate location and ensure I give the full path to the script in step 4?
Thanks

Nanjunder
it is very good trick will help most DBAs to avoid rebuilding or spending time on restoring log and searching for missed log with Backup Team.

Comment on RMAN -Recovery from missing or corrupted control file by Tallarico

Wow! Thanks for the great site! You’ve earned a faithful reader. Keep up the great work!

Question for you:
If I’m doing a full database restore on a different server from where the RMAN backups were taken how do I tell to what point-in-time (or sequence number) that I can do a restore and recover to?

The scenario is that my backup administrator retrieved a full backup (.arc, .bak, and backup control files). I’ve cataloged them successfully and eventually was able to restore the database. However it was very difficult!

Some of the datafiles’ backups in the fileset had expired whereas others were good up until a different point-in-time. Finding a common point-in-time for which all datafiles could be restored to from the backup set provided me was very difficult.

Do you have any suggestions?

Thanks again for a wonderful site!
