Description and Workaround or Solution
|
|
|
|
|
When creating a custom metric for a process group, if you attempt to create another custom metric without an intervening page refresh, the list of process groups is not populated.
Refresh the page before trying to create another custom metric.
|
|
|
|
|
When toggling a chart’s Show Title preference from on to off, and then back to on again, the title does not appear until the page is refreshed. The Show Title preference value is saved correctly however.
Refresh the page after toggling the Show Title option on or off.
|
|
|
|
|
When pausing a chart on the Monitoring page, the text “Pause” appears in the chart title and is replicated while the chart is paused.
|
|
|
|
|
Upon selecting a chart on the Monitoring page, the chart is given visual focus with a blue border. However, the only way to remove that focus is to choose another chart, leave the page and come back, or set preferences for the chart, which also clears it. The chart having focus only affects preferences currently being read and/or set on the chart.
|
|
|
|
|
When using the Coherence Smart Pack sum metric ( ClusterNodeMBean.MemoryAvailableMB), the metric value is not plotted in the graph on the Monitoring page.
Try to construct a comparable custom metric or monitor values individually for each endpoint.
|
|
|
|
|
When importing service metadata from a WebLogic domain configuration, the Administration Console does not validate that the path and file entered are valid from a file-system perspective, which results in an error.
Verify that the entered path and filename are correct before attempting to re-import the service metadata again.
|
|
|
|
|
On the Process Group page, when clicking the Remove Process Group button without first selecting a process group, no message is printed indicating a choice must be made; therefore, the operation is a NOOP.
|
|
|
|
|
If you click Run Action on the Actions page or Run Pipeline on the Pipelines page without first selecting an action or pipeline, you are presented with the appropriate dialog, but the action or pipeline name is blank. This is because the user is not first prompted to select an action or pipeline.
Cancel out of the dialog and select an action or pipeline to run.
|
|
|
|
|
If you select Unassign Policy on the Active Policies page without first selecting a policy, a subsequent attempt will fail even if you select a policy.
Refresh the Active Policies page before trying to unassign a policy again.
|
|
|
|
|
While browsing the Interactive topology view, the focus of the node users are attempting to click on may not be clear, which can cause incorrect expansion of selected node.
|
|
|
|
|
When a CRON process constraint is used to stop multiple instances, the Administration Console’s count of running processes for that service may not be updated.
|
|
|
|
|
When performing approval actions using the Approvals table, no confirmation message appears at the top of the page. A message should appear in the Event Viewer indicating whether the approval was approved or denied.
|
|
|
|
|
When performing actions using the Service Detail page, a warning message may appear indicating further action is required, such as “Please select a process group”. After selecting a process group and finishing the action, the message may still appear.
Manually refresh the page to remove the message.
|
|
|
|
|
In some cases, the visual state of a running process may not change without a manual refresh of the page.
|
|
|
|
|
When creating a new Agent binding you cannot set its initial state.
Use the Agents table to change the Agent state.
|
|
|
|
|
When cloning a process group from the service details page, if you click Cancel, and then try to re-enter the clone process again, you may experience an exception.
Try navigating to the service details page again or simply refresh the page.
|
|
|
|
|
When defining new JVMs for a service, you can create variables, but you cannot specify the variable in the Port field during the same assistant/wizard flow.
You can later go into the JVM definition and specify the Port variable name to use.
|
|
|
|
|
In Firefox browsers, the chart resize icon may appear misaligned with the lower-right corner of the chart that it resides in.
|
|
|
|
|
While creating a new action, if you use the Back button to return the first page, the previously selected action type is not persisted.
While creating a new action, if you back up to the first page, you will need to explicitly reselect the action type that you want to create.
|
|
|
|
|
In certain scenarios, a session may time out while using the Administration Console. For example, you may click a button or link and be prompted to authenticate before continuing. Upon re-authenticating, you may be directed to the last resource you clicked on, but without the full context or decoration of the console application window.
Re-enter the main Administration Console URL again.
|
|
|
|
|
Depending on the complexity of the user’s inventory, the Interactive topology view (Tree) diagram in the Inventory pane may overlap nodes, making them difficult to read.
Collapse nodes to reduce the complexity of the diagram and minimize overlap.
|
|
|
|
|
When viewing the interactive view of the Inventory pane, if a JVM or service life cycle change occurs (for example, the service gets undeployed) the topology diagram does not dynamically update to reflect the life cycle change.
|
|
|
|
|
If you attempt to log in to the WLOC Administration Console using a user account that is not assigned to any roles and subsequently receive a 403 error, you must open a new browser before attempting to log in again.
|
|
|
|
|
When an Agent is restarted, the WLOC Administration Console may show the state of JVMs managed by that Agent as unreachable even after the Agent is fully running. In addition, when the Controller is restarted, the JVMs that it manages may not show up in the Inventory pane.
Refresh the browser window.
|
|
|
|
|
You may experience problems viewing configuration information in the following situations:
- When a JVM is added to the Inventory pane initially, the full association of the JVM instance to its service and process group may not be known. Consequently, when you click the name of the JVM instance, the complete details of the JVM instance may not display on the JVM instance page.
Workaround or solution:
Refresh the browser page.
- If one or more spaces are used in the service, process group, or JVM instance name, the complete details of the JVM instance may not display on the JVM instance page.
Workaround or solution:
Delete and recreate the service, process group, or JVM instance without using spaces in the name.
|
|
|
|
|
If you manually start a JVM instance using the Run Action method, the JVM instance may not appear dynamically or its performance chart may not appear correctly in the WLOC Administration Console.
|
|
|
|
|
WLOC does not support nested groups. If you use nested groups, you may encounter the following issues:
- Users that are members of a nested group do not get the permissions that they should.
- Deleting a group that is a member of a second group does not remove the group name from the second group.
Oracle recommends that you do not create nested groups in WLOC 1.0.
|
|
|
|
|
When viewing a chart with a large Y-axis values, the values may overlap with the Y-axis label.
Position the mouse pointer over a data point to view the current value. You can hide the axis labels using the chart preferences, if necessary.
|
|
|
|
|
While viewing the Inventory pane, in certain circumstances a node labeled loc may appear. This node represents internal state that the WLOC Administration Console uses to contain inventory nodes and can be ignored.
|
|
|
|
|
When defining a process group, if you are importing from another service, running WebLogic domain, or WebLogic domain configuration, if you select the following flags:
- Allow me to choose instances to import
- Show me a summary of uncollectable metadata from config.xml
and then click the Back button, you are returned to the Service Properties page (the first page of the service assistant).
|
|
|
|
|
When viewing the Inventory pane, entries do not appear in alphabetical order.
|
|
|
|
|
When viewing the interactive view of the Inventory pane, when a service life cycle change occurs, for example, a service gets added or deleted, the change may not be reflected in the currently viewed diagram.
|
|
|
|
|
Deleting the JVM file copy operations from the File Management page using the WLOC Administration Console has no effect. The entries are not removed.
Delete the file copy operations directly from the metadata-config.xml file located in the config directory of the Controller installation.
|
|
|
|
|
In some high availability circumstances, the performance graphs for a service may not reflect a problem condition. For example, when the chart is plotting a negative value (-1). Under normal circumstances, the message Problem Detected would be displayed next to the data series in the chart legend.
Check the Tasks and Event viewer, Events tab, or log files for potential error conditions.
|
|
|
|
|
When creating a file copy operation for an ISO constraint, the Copy Type drop-down list includes the At Shutdown option. This option is not valid for an ISO constraint file copy operation.
Do not select this option for an ISO constraint file copy operation.
|
|
|
|
|
If you do not have the appropriate permissions to view the Agent configuration (for example, if your user account is assigned to the ServiceAdmin role only), you will not be able to view the configured software when you click the Available Software tab for the associated resource pool. The Available Software table will appear empty even if there is software configured for the Agent.
|
|
|
|
|
When creating a new constraint, after you select a type and click Next, if you go back to the initial screen using the Back button, the Type value returns to the default value.
Reselect the type and proceed.
|
|
|
|
|
When importing service metadata from a running WebLogic domain, the host parameter may include the DNS and IP address form of the host address. This may occur when connecting to the Administration server in some environments.
Edit the address, as required.
|
|
|
|
|
In some circumstances, you may receive a Javascript error in Microsoft Internet Explorer 6.0 when attempting to save a JVM instance configuration.
Try the operation using the Mozilla Firefox (or another) browser.
|
|
|
|
|
When using Mozilla Firefox 1.5 or above, you may experience repaint problems on smaller or laptop monitors when scrolling pages with tab controls at the top.
Resize the browser window by dragging its edges or maximizing it.
|
|
|
|
|
When deleting connection or connection factory entries, the Connections page may refresh too quickly causing the entries to reappear as if they were not deleted.
Refresh the browser window.
|
|
|
|
|
When you configure a console notification to add an icon to an element in the user interface (for example, the Services table), upon subsequent visits to the Service table, Monitoring tab, or Inventory pane, the icon is not present.
The icon should appear the next time the constraint is triggered and the console notification is executed.
|
|
|
|
|
When viewing a constraint in the Constraints table that was configured with an event status of succeeded, the configured status appears as failed.
Clicking on the rule definition shows the correct status.
|
|
|
|
|
When navigating a table with more than 10 entries, the to value (shown below) in the table page navigation located above the table may reflect an incorrect value.
|
|
|
|
|
The Tasks and Events viewer displays the most current entries at the top of the viewer by default. If you refresh the browser window the order is reversed and the most current entries are displayed at the bottom.
|
|
|
|
|
When adding a process group to a service, if you select Import from another service, you may experience an error on the service selection screen.
Try importing from a different service or from another source, such as a running WebLogic domain, creating the process group from scratch, or cloning another process group or JVM instance from the Service page.
|
|
|
|
|
You may encounter an error when importing a process group from a service if you rename the process group during the import process.
Try importing the process group from a service without changing its name.
|
|
|
|
|
When adding two process groups or JVM instances to a service back-to-back (without refresh), both items may not be registered as being added.
Refresh the page between each add operation to ensure all process groups and JVM instances are added.
|
|
|
|
|
In some cases, following a Controller restart the Inventory pane may appear empty on initial display because of problems reading the user inventory.
Refresh the browser window.
|
|
|
|
|
When creating a policy, if you select the “Based on the value of an attribute or function” option, click Define Custom to define a custom metric, and you modify the instance portion of the generated metric prior to clicking the Finish button to create the policy, the change is not recognized.
|
|
|
|
|
If you attempt to log in to the WLOC Administration Console using a user account that is not assigned to any roles, you will see entries in the Inventory pane including resource pools and JVMs representing runtime data. However, when you click on the entries, you will not see any data because you are not authorized.
|
|
|
|
|
If you save a blank password when configuring a JVM instance, when viewing the configuration you may see a string with the value of null in the JVM password field.
Clear the password field and save the JVM configuration.
|
|
|
|
|
The Filter tool that appears at the top of some pages in the WLOC Administration Console only sorts information on the current page.
|
|
|
|
|
If you attempt to delete a monitoring view that has charts associated with it, you may encounter an error.
Delete all charts associated with the view before deleting it.
|
|
|
|
|
Use of multi-byte character sets for the display and update of data may cause problems with the WLOC Administration Console.
Whenever possible, use English Locale when using the WLOC Administration Console.
