Nice bug

Today I was trying to enable automatic patch update in 11g.
I opened a configuration page and typed my email and password, when I pressed Apply
button I saw a nice information in red:

Invalid Data - Error: apply failed ORA-12899: value too large for column
"SYSMAN"."MGMT_ARU_CREDENTIALS"."ARU_USERNAME" (actual: 80, maximum: 64)
ORA-06512: at "SYSMAN.MGMT_CREDENTIAL", line 1482 ORA-06512: at line 1

On Metalink your account is your email, so all DBA's with long first or surnames have a problem ;)
I have make a manual research and I have found a solution - use shorter account name.

BTW this is solved in 11.1.0.7
From Metalink note 470696.1

The next Release of DB Control (11.1.0.7) will include the fix. The maximum length of the Metalink Username will be 255 characters (as Metalink username can have up to 255 characters).

I will try that.

update:
Even in 11.1.0.7 on Linux I cound not use my metalink account.
