ORA-03113: end-of-file on communication channel after long inactivity in ASP.Net app

Question

I\'ve got a load-balanced (not using Session state) ASP.Net 2.0 app on IIS5 running back to a single Oracle 10g server, using version 10.1.0.301 of the ODAC/ODP.Net drivers.

Answer 1

end-of-file on communication channel:

One of the course of this error is due to database fail to write the log when its in the stage of opening;

Solution check the database if its running in ARCHIVELOG or NOARCHIVELOG

to check use

select log_mode from v$database;

if its on ARCHIVELOG try to change into NOARCHIVELOG

by using sqlplus

• startup mount
• alter database noarchivelog;
• alter database open;

if it works for this

Then you can adjust your flashrecovery area its possibly that your flashrecovery area is full -> then after confirm that your flashrecovery area has the space you can alter your database into the ARCHIVELOG
