When configuring cassandra.yaml, take note of the following:

  • There is a space before each IP address for parameters listen_address and broadcast_rpc_address. The space is required for Cassandra to start.
  • When entering the parameters to configure cassandra.yaml, be sure that there is no '#' (pound sign) or 'space' before the parameter name. If there is a #, for example, #broadcast_rpc_address: 10.1.1.123, this value will become a comment. If there is a space before the parameter name, for example, <space>#broadcast_rpc_address: 10.1.1.123, you will get an error after starting Cassandra.

Frequently Asked Questions

I cannot log in with the default Administrator user via

TWCloud

Teamwork Cloud Admin UI. What could be the cause of the problem?

There are several causes of Administrator's login failure such as:

  • Cassandra is not started so TWCloud Teamwork Cloud cannot connect to it.
  • Cassandra is started but TWCloud Teamwork Cloud cannot connect to it due to Cassandra and/or network configuration problem.

To find out what the cause of the problem is, you need to look at the log file and check the status of Cassandra. See Troubleshooting section for more information.

Where can I find the

TWCloud log

Teamwork Cloud log file?

The default log file location is <user home folder>/.twcloud/<version number>.

  • The log file of TWCloud Teamwork Cloud is called called server.log.

How do I check

the

Cassandra status?

Cassandra provides a nodetool utility, which is a command-line interface for managing a cluster. You can use it for checking the cluster status.

  • On Linux, type: 

    Code Block
    languagebash
    themeDJango
    linenumberstrue
    $ nodetool status
  • On Windows, type: 

    Code Block
    languagebash
    themeDJango
    linenumberstrue
    C:\> "%CASSANDRA_HOME%"\bin\nodetool status

The following is an example output from running the nodetool status. 

Code Block
Starting NodeTool

========================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address     Load       Tokens   Owns    Host ID                               Rack

UN means that the status is up and normal.

How do I check if

TWCloud

Teamwork Cloud has a problem connecting to Cassandra?

You can check it from the log file of TWCloud. If TWCloud Teamwork Cloud. If Teamwork Cloud cannot connect to Cassandra during the TWCloud startup Teamwork Cloud startup process, a log message similar to the following will appear and the server will shut itself down. 

Code Block
INFO  2016-01-04 11:12:32.131 Connecting to Cassandra [CoreManagerComponent, Component Resolve Thread]
ERROR 2016-01-04 11:12:50.351 Connection to Cassandra failed due to timeout [CoreManagerComponent, Component Resolve Thread]

You may also find yourself in a situation where TWCloud Teamwork Cloud has been started successfully but the problem connecting to Cassandra occurs later. If this happens, a log message similar to the following will appear. 

Code Block
WARN  2016-01-04 13:57:26.034 There was a problem with the connection between the TWCLOUD server and Cassandra

What should I see in the

TWCloud

Teamwork Cloud log file, which indicates that

TWCloud

Teamwork Cloud has been successfully started?

If TWCloud Teamwork Cloud has been successfully started, you will see a log message similar to the following in the log file. 

Code Block

How can I use the netstat command to see if the ports are bound?

  • On Linux, type 

    Code Block
    languagebash
    themeDJango
    linenumberstrue
         netstat –an | grep :8111 and netstat –an | grep :8555
  • On Windows, type 

    Code Block
    languagebash
    themeDJango
    linenumberstrue
    Netstat –ano | find “:8111” and Netstat –ano | find “:8555”

I cannot see the project history or branch or perform any operations related to the project history from MagicDraw. What could be the cause of the problem and how to solve it?

You need to check if it is a known issue by looking at the server.log file. If you see the following ERROR message, it is a known issue.

Code Block
languagetext
com.esotericsoftware.kryo.KryoException: Buffer overflow

You can solve this issue by adding the following code line at the end of the configuration file, <TWC <Teamwork Cloud install folder>/configuration/application.conf.

Code Block
languagetext
esi.serializer.max-buffersize = -1

After updating the configuration, you will need to restart TeamworkCloud.

Troubleshooting

The

TWCloud installer

Teamwork Cloud installer is not started on Windows

If you run the installer file and the installer UI does not show up or receive the message: "Windows error 2", try the following workaround.

  1. Start the command prompt by selecting "Run as administrator".
  2. Start the installer from the command line and use the option LAX_VM followed by the location of java.exe. For example: 
    C:\> twcloud_190_beta_installer_win64.exe LAX_VM "C:\Program Files\java\jdk1.8.0_152\bin\java.exe"

I cannot uninstall

TWCloud using

Teamwork Cloud using uninstall.exe

If you run uninstall.exe and the uninstall UI does not show up or receive the message "Windows errors", try the following workaround.

  1. Start the command prompt by selecting "Run as administrator".
  2. Start uninstall.exe from the command line and use the option LAX_VM followed by the location of java.exe. For example: 
    C:\> uninstall.exe LAX_VM "C:\Program Files\java\jdk1.8.0_152\bin\java.exe
TWCloud cannot

Teamwork Cloud cannot connect to Cassandra

If the TWCloud server Teamwork Cloud server log shows the following message: 

Code Block
INFO  2016-01-04 11:12:32.131 Connecting to Cassandra [CoreManagerComponent, Component Resolve Thread]
ERROR 2016-01-04 11:12:50.351 Connection to Cassandra failed due to timeout [CoreManagerComponent, Component Resolve Thread]


It means that TWCloud cannot Teamwork Cloud cannot connect to Cassandra and this is usually caused by the following reasons:

  • Cassandra is not started.
  • Cassandra is started but it is not properly configured for cloud. You need to make sure that you follow the Cassandra configuration instruction and that you restart Cassandra after updating the configuration. You can find the configuration instruction from the following links:
TWCloud fails

Teamwork Cloud fails to start, and a message about AssociationError appears in the log file

If the TWCloud server Teamwork Cloud server fails to start and an error message similar to the following appears in the log file: 

Code Block
ERROR 2016-01-04 13:12:58.104 AssociationError [akka.tcp://twcloud@127.0.0.1:2552] -> [akka.tcp://twcloud@10.1.1.123:2552]: 
Error [Association failed with [akka.tcp://twcloud@10.1.1.123:2552]] [akka.remote.EndpointAssociationException: 
Association failed with [akka.tcp://twcloud@10.1.1.123:2552]

You need to check if the hostname can be resolved to the IP that you specified while installing TWCloud Teamwork Cloud

From the log message given in the example above, you will see two IP addresses in the message 127.0.0.1 and 10.1.1.123. They mean that you have specified the IP address 10.1.1.123 during TWCloud installation during Teamwork Cloud installation, however, your hostname is resolved to loopback IP 127.0.0.1.


You can configure how your machine resolves the hostname from the hosts file. The location of the hosts file:

  • On Linux: /etc/hosts
  • On Windows: %SystemRoot%\system32\drivers\etc\hosts


You can check what IP address is resolved from the hostname by using the following steps:

  • On Linux:

Execute the following command 

Code Block
languagebash
themeDJango
linenumberstrue
$ resolveip -s $(hostname)
  • On Windows

Step 1: Find hostname of the machine. 

Code Block
languagebash
themeDJango
linenumberstrue
C:\> hostname

Step 2: Use the ping command followed by the hostname you got from Step 1. For example, if your hostname is my-machine, use the command. 

Code Block
languagebash
themeDJango
linenumberstrue
C:\> ping my-machine
