I am working on SAP Java Portal upgrade from NW 7.3 to 7.4. While SUM enter in execution phase, security team changed the credentials of “Administrator”. due to this upgrade got stuck & i am not able to change password back to same in Portal.
I performed the same through telnet by following below method. before performing this i change UME parameter in config tool & restart the cluster.
Change minimum length of password – 4
Keep password history – 3
telnet localhost 50008
Enter user name
enter current password
Type – add user
enter current password — click Enter
enter user – Administrator
enter new password
confirm new password
Now you can set same password what you have given during Configuration Phase in SUM & continue to upgrade.
Let me know if this works for you.
