❖Share File Deployment
During the startup of each node, two jar packages product-swf.jar and product.jar will be used. If the update of these two packages need to be done on all nodes, the update can be done in Dashboard.
Click "upload" link, as shown in the image below,
The page "importing resource" pops up, click "browser" to choose files, and click "OK" then the upload is complete.
After the successful uploading, check the uploading progress to each node of file from "File Upload Result" at the table below.
The file can be added to the two directories bihome/ and PRODUCT_HOME/Yonghong/ and the corresponding sub-directory.
As the image blow, input the name of file to be added, choose a directory, or input the name of sub-directory, click the button "add", then the name of newly added file will appear under the "shared file" at the table below, then click the "upload" link following the name of new file, the file to be added shall be uploaded.
❖MPP Parameter
This dashboard is used for revising the global parameter of MPP mart, i.e., the parameter in global_bi.properties.
•Click the cell global parameter value to revise the content of parameter
•Right click delete row on the menu to delete certain parameter
•Add certain parameter by right clicking insert row
After completing the revision, click "Commit" button to complete the revision.
After the successful revision, we can view the synchronization of the parameters on each node from "Parameter Modification Result" at the table below.
In the current cluster configuration, one global_bi.properties configuration file is available for each node, and the file global_bi.properties of all nodes in the same cluster are consistent by default. However, under certain circumstances, if the user manually revises global_bi.properties of one node or multiple nodes, the configuration file global_bi.properties of node in the cluster might be inconsistent or incorrect, which might result in the abnormality of node that without the correct configuration, and the user cannot sense whether the parameter configuration of each node in the cluster is consistent.
Therefore the function of testing global_bi.properties configuration is added in mart console part, which can enable the user to sense the inconsistent parameter configuration of each node, then the global_bi.properties configuration can be revised uniformly.
If the global parameter configuration is inconsistent, "inconsistent" shall be displayed in the cell of global parameter value, the user can define the configuration value on the different nodes of this parameter according to the detailed parameter value, then the global parameter on all nodes can be revised to the consistent parameter value by revising the parameter functions.
❖MPP State
This dashboard is used to view the status of each node in the mart, and to start,stop,restart the node.
By choosing the status of node or the type of node, filter the node that needs to be checked, we can startup, stop or reboot the node.
One node in MPP mart system corresponds one console. When the console on the node is started, the working status of each node will be monitored. When the node is down, console can automatically start the node in certain time interval, and the default time is 30s. The time interval can be set through the attribute node.start.delay=30.
