Q1.01 |
If you install PPM under Windows Vista, Windows Server 2008, or Windows 7 the installation is incomplete. Cloud Agent cannot be set up as a Windows system service. Why? |
|
The above Windows operating systems have stricter security policies. Run the installation program as an administrator (pop-up menu item Run as administrator). Other user accounts do not work, even if they were assigned administrator privileges. |
|
|
Q1.02 |
Which network resources does a PPM system require? |
|
For detailed information, refer to the PPM system architecture documentation (PPM network/Network protocols chapter). |
|
|
Q1.03 |
How can the PPM installation be protected against unauthorized access? |
|
To protect your PPM installation against unauthorized access, you can use the operating system's file access privileges. Note that the operating system user whose ID is used to start system services (the Windows default is the SYSTEM user) has full access privileges for the directory structure. |
|
|
Q1.04 |
Does PPM support NAT (NetworkAddressTranslation)? |
|
The http or https protocol used by the PPM user interface supports NAT. Therefore, running PPM in a public cloud environment is possible provided the system is only to be accessed externally using the PPM interface. The Java RMI protocol used by PPM for the command line programs does not support NAT. Therefore, running PPM in a public cloud environment is impossible if the system is to be accessed externally using the command line programs. |
|
|
Q1.05 |
Can https be used to access PPM? |
|
Yes. The load balancer supports https since PPM 9.0 by default. However, you need to note that a self-signed certificate generated during installation is used. This leads to error messages in most browsers. See also chapter https support |
|
|
Q1.06 |
How can data transfer between PPM server and user interface be encrypted (SSL encryption)? |
|
See Safe communication channels chapter. |
|
|
Q1.07 |
What is the "server" mode on a PPM server? |
|
The server option is configured during installation of a client. If the option is enabled, the PPM server uses the Java VM version optimized for server applications. To use this option, you must use a Java SDK version for the PPM server. |
|
|
Q1.08 |
How do I change the Java Runtime Environment used by the PPM server? |
|
It is impossible to change the Java Runtime Environment. From PPM 9, only the one supplied can be used. |
|
|
Q1.09 |
When using PPM with MS Internet Information Server (IIS), I cannot access PPM. Why? |
|
From PPM 9.0, IIS is no longer supported. |
|
|
Q1.10 |
It is impossible to connect to a PPM client server. The extended information in the login dialog states that the computer name of the PPM client server is unknown. What is the reason for this? |
|
Possible causes:
|
|
|
Q1.11 |
The connection to the PPM server fails. Example message in log output: Client "umg_en" does not exist. Error connecting to server. Trying to connect PPM server //pcppm:16300/ppm_rmi_server_umg_en ppm_rmi_server_umg_en java.rmi.NotBoundException: ppm_rmi_server_umg_en |
|
The required client server may not have been started or the specified client name is not correct. If the client server is running, it is also possible that the PPM RMI registry has been restarted, for example, due to an unexpected system incident. In this case, restart the client server. |
|
|
Q1.12 |
Does PPM support the use of a cross-company directory service? |
|
The LDAP interface integrated into central user management allows particular users to be transferred. The users transferred from the LDAP system are authenticated synchronously against the corresponding LDAP system. |
|
|
Q1.13 |
What is important about environment variables? |
|
Since PPM 9.0, environment variables have no longer been supported. |
|
|
Q1.14 |
What is a client-specific configuration file? |
|
For each PPM client installed, a directory of the same name exists in the subdirectory <installation directory>\ppm\server\bin\work\data_ppm\config. This directory contains the component-specific configuration files for the client server and analysis server. These text-based configuration files have the extension _settings.properties. |
|
|
Q1.15 |
What is a system-wide configuration file? |
|
The system-wide configuration files specify global settings for the entire PPM system and are saved under <installation directory>\ppm\server\bin\work\data_ppm\config. |
|
|
Q1.16 |
How do I change the TCP/IP ports of the PPM services? |
|
You change the TCP/IP ports using Cloud Controller. Further information on the individual commands is available in the help of the Cloud Controller command line. You can view the help by entering the command help in the command line.
|
|
|
Q1.17 |
What does the key CorbaServerActivationPort mean in the configuration file Registry_settings.properties? |
|
The Corba registry server uses this socket for control at runtime. This feature cannot be disabled. |
|
|
Q1.18 |
Since the update to Chrome Web browser version 45.x and higher, the PPM front-end cannot be loaded as an applet any more. What is the reason for this, and is there a solution? |
|
For Google Chrome Version 45 or later, the Java applet is no longer supported. There is no direct solution for executing the applet under Google Chrome. As an alternative to the applet, PPM Version 9.10 onwards supports Web Start. To download and run the PPM GUI on the client, you only have to download the new PPM Web Start file from the Web server. To do this, enter the following URL after installing and launching the infrastructure in the browser: http://<hostname>:<port>/ppm/html/ppm.jnlp. |
|
|
Q1.19 |
When installing PPM, errors occur when the required Visual C++ Redistributable packages are installed. What can be done? |
|
There are two possible causes.
