cannot logon to SAP system after changing parameter

Hi,

I cannot login to SAP system after changing and reverting parameter COMPATIBLE.

History of events:

1. I checked DB16 and the COMPATIBLE parameter was on error:

Value: 10.2.0.3.0 (<> 10.2.0) # Database compatibility mode

2. I tried to change the parameter to the recommended value on SAP note 830576:

ALTER SYSTEM SET COMPATIBLE = '10.2.0' SCOPE=SPFILE;

3. When trying to restart the database I had an error message

so I reverted the parameter to the previous setting with:

ALTER SYSTEM SET COMPATIBLE = '10.2.0.3.0' SCOPE=SPFILE;

4. SAP was started and everything is green:

5. But, when trying to logon, I get an error message when trying to open the logon screen

Please let me know how to solve this.

thanks

Antonio

    Hi Antonio,

    Please share the output result for command R3trans -d and share trans.log file for analysis.Additionally share dev_w0 log file as well.

    Hi Antonio,

    If possible share alert_<SID>.log file also,as there may be chances of corruption of control file as well.
