SYS password not recognized on WebDB reinstall

[hhawhee]

I installed WebDB on an NT server, then uninstalled it. During the de-installation, it asked me for the SYS password. When I used the one that always has worked before (change_on_install), it told me that the password is invalid.<br>
<br>
When I try to reinstall, I have the same problem.<br>
<br>
possibly related issue: I can log into SQL*Plus as Scott/Tiger. However, when I try SYS/change_on_install, I get the message ORA-01925: maximum of 20 enabled roles exceeded.<br>
<br>
Any thoughts?<br>

The help text for this error message states:<br>
<br>
ORA-01925: maximum of num enabled roles exceeded <br>
<br>
Cause: The specified number of enabled roles exceeds the value specified in the initialization parameter MAX_ENABLED_ROLES. <br>
<br>
Action: Increase MAX_ENABLED_ROLES and restart the instance. <br>
<br>
So I'd say shutdown the instance, edit init.ora, and startup the instance again.<br>
