The mxmc_rt (or <database prefix_rt user ) users' password is changed at database level. Afterwards the Dispatcher fails to connect to the Idm database
The password of the runtime user is updated in the IdM application through the .MMC console in the Database tab of the Identity center top node. Here there are two connection strings 1. Windows RT conn string and 2. Java RT JDBC URL. For the update of the password to succeed it must be entered in both connection strings (even if you do not have a windows dispatcher configured). Afterwards then the dispatcher scripts must be regenerated.
