FAQ

Such and error may occur in 2 cases: A. the username and password used to access the Global InfoBase are not correct and/or B. the Muse communication with Global InfoBase is not successful. A. The u/p used to access the Global InfoBase are set for each admin user via Designer console or Muse Console for Applications Administration. Using Muse Console for Applications Administration (starting with Muse 2300), the Global InfoBase u/p can be changed as following: – log in Muse Console for Applications Administration, – go to “Users”, – select a user and click “Edit Properties”, – in the window that opens, set the “Global InfoBase User Name” and “Global InfoBase User Password”. Using Designer Admin console (before Muse 2300), the Global InfoBase u/p can be changed as following: – log in Designer console, – go to “Users”, – click “Muse Admin Bridge” , – click “Properties” of the admin user that must be checked, – in the window that opens, set the “Global InfoBase User Name” and “Global InfoBase User Password”. B. Unsuccessful communication between Muse and Global InfoBase can be caused by a transparent HTTP proxy between the two. The communication with Global InfoBase is based on XML requests and responses over TCP sockets. Many HTTP proxies cannot handle such XML requests and responses because the communication is not over the HTTP protocol and thus a HTTP proxy cannot handle it, because it tries to understand HTTP headers. Because of that, the message presented to the user is (Global InfoBase error: … Wrong user name or password.) since Muse does not get back a message confirming the successful authentication to Global InfoBase. The best solution for this case is to give full Internet access to the Muse server or at least to factory.museglobal.com:80. If this is not possible due to special security policies, we recommend the following workarounds:

• if the outgoing communication to port 8005 is not passed through the transparent proxy (and if there is no firewall blocking such requests on client side), change the port in the $MUSE_HOME/factory/SourceFactory.xml from 80 to 8005 (e.g. enter 8005 as value in the "" field).
• switch the communication of the Muse server with SourceFactory on SSL. Even if the traffic passes through proxy, being on SSL, the proxy will not interfere and the communication will stand. To do this, change the port in the $MUSE_HOME/factory/SourceFactory.xml from 80 to 443 (e.g. enter 443 as value in the "" field) and also set field to "yes". Please note that this option is only available fro Muse versions 2.3.1.1 and above.

Note: After such a port change, Muse HTTP server/Apache Tomcat must be restarted.

This is explained in the “Adding a new slave machine to the environment” chapter from the “Muse Advanced Configuration.pdf” manual.

In a shared Muse environment all files are shared, including the $ICE_HOME/serial.properties file containing licensing information and necessary for the ICE to start.

When adding new servers to a Muse cluster one cannot just run the Registration process to register the new machine because of the following reason: Muse was not installed on the new machine using the Muse setup kit, hence the InstallShield files necessary for running the Registration do not exist.
In the shared Muse environment the Muse files are loaded/mounted from the master machine.

Below are the steps to be performed when a new slave machine is added into the Muse environment after the initial setup an it needs to be registered:

1. An “Extension Request” procedure for the Serial Number is performed to add all IPv4 and IPv6
IPs of the new machine to the Serial Number in use. In case the Serial Number already contains the IPs of the new machine then there is no need to run the “Extension Request” and the Muse servers can be started on the new machine (step 4).
2. After the extension request is processed by MuseGlobal, the Muse Registration Setup must be run on the master machine.
3 A synchronization of the slave machines with the master must be performed in order for the new serial.properties file to get on the new machine.
4 The Muse servers can now be started on the new machine.
