Galaxy Note 4 Battery Life After Updating to Lollipop 5.01

My Samsung Galaxy Note 4 recently received the update to Lollipop 5.01, and as a result, suffered significant degradation in battery life. Samsung supported provided me with the following remediation steps that have thus far corrected the problem.

1. Power the device off.
2. Hold (do not press)
1. Volume down
2. Home
3. Power
3. A warning screen will appear.
1. A custom OS can cause critical problems in phone and installed applications. If you want to download a custom OS, press the up key. Otherwise, press the volume down key to cancel.
4. Press volume down to cancel.
5. When the device boots up and displays the lock screen, power the device off again.
6. Hold (do not press)
1. Volume up
2. Home
3. Power
7. The Android image will appear with a message below indicating, 'Installing system update.."
8. The Android System Recovery menu will appear.
9. Use the volume button to select "wipe cache partition"
10. Press the power button to invoke the operation.
11. Select "reboot system now" that should be selected by default
12. Press the power button to invoke the operation.

Get Selected Row of ADF Tree

I needed to get some information contained in the selected row of an ADF Tree component.

/* START PRESERVE DEFAULT ADF SELECT BEHAVIOR 
 * Courtesy of Frank Nimphius - https://blogs.oracle.com/jdevotnharvest/entry/how_to_read_data_from */

FacesContext fctx = FacesContext.getCurrentInstance();
Application application = fctx.getApplication();
ELContext elCtx = fctx.getELContext();
ExpressionFactory exprFactory = application.getExpressionFactory();

MethodExpression me = null;
me = exprFactory.createMethodExpression(elCtx, adfSelectionListener, Object.class, new Class[] {SelectionEvent.class}); 
me.invoke(elCtx, new Object[] { selectionEvent });  
/* END PRESERVE DEFAULT ADF SELECT BEHAVIOR */

RichTree tree = (RichTree)selectionEvent.getSource();
TreeModel model = (TreeModel)tree.getValue();

// get selected nodes
RowKeySet rowKeySet = selectionEvent.getAddedSet();
Iterator rksIterator = rowKeySet.iterator();

while (rksIterator.hasNext()) {
   List key = (List)rksIterator.next();
   JUCtrlHierBinding treeBinding = null;
   CollectionModel collectionModel = (CollectionModel)tree.getValue();
   treeBinding = (JUCtrlHierBinding)collectionModel.getWrappedData();
   JUCtrlHierNodeBinding nodeBinding = null;
   nodeBinding = treeBinding.findNodeByKeyPath(key);
   Row row = nodeBinding.getRow();
   // Get the LexisAccountNumber and enable the delete image link
   String value = row.getAttribute("someAttribute").toString();
}

Invoke ADF Data Control Operation via Bindings Layer

Assumptions:

• You have created a data control.
• You have created a methodAction binding for the respective operation on a page.

package com.bjwallen.examples;

import oracle.binding.AttributeBinding; 
import oracle.binding.BindingContainer;
import oracle.binding.OperationBinding;
import oracle.adf.model.BindingContext;

public class BindingsExample{

  public BindingsExample(){
    super();
  }

  public void invokeOperation() {
    // get a handle on the bindingContainerBindingContainer
    bindingContainer = BindingContext.getCurrent().getCurrentBindingsEntry();
    
    // get a handle on the operation you want to invoke
    OperationBinding operationBinding = bindingContainer.getOperationBinding("yourOperation");
    
    // get a handle on an attribute that is bound to some component on a page
    AttributeBinding yourAttr = (AttributeBinding)bindingContainer.getControlBinding("yourComponentBinding");
    
    // put the value of the attribute in an operationBinding map
    operationBinding.getParamsMap().put("yourKey", yourAttr.getInputValue().toString();
    
    // invoke your operation
    operationBinding.execute();
    
    // check for any exceptions
    if (!operationBinding.getErrors().isEmpty()) {
      // handle exceptions accordingly
    }
  }
}


If you're dealing with complex types in the WSDL, you can update the request using the DCBindingIterator.

// cast your bindingContainer to a DCBindingContainer
DCBindingContainer dcBindingContainer = (DCBindingContainer)bindingContainer;

// get the data control iterator
DCIteratorBinding dcIteratorBinding = dcBindingContainer.findIteratorBinding("yourIterator");

// update the row with the value of an attribute bound to a page
Row row = dcIteratorBinding.getCurrentRow();
String value = yourAttr.getInputValue().toString();
row.setAttribute("DateTime", value);

JDeveloper Cannot Establish Connection or Local Host Not Known When Connecting to Application Server

I updated to OS X Yosemite recently. After which, I experienced some issues with JDeveloper when trying to create a connection to an Application Server. I observed the following exceptions:

Testing JSR-160 Runtime ... failed.
Cannot establish connection.
Testing JSR-160 DomainRuntime ... skipped.
Testing JSR-88 ... skipped.
Testing JSR-88-LOCAL ... skipped.
Testing JNDI ... skipped.
Testing JSR-160 Edit ... skipped.
Testing HTTP ... success.
Testing Server MBeans Model ... skipped.
Testing HTTP Authentication ... success.

and

Testing JSR-160 Runtime ... failed.
Local host not known?!
Testing JSR-160 DomainRuntime ... skipped.
Testing JSR-88 ... skipped.
Testing JSR-88-LOCAL ... skipped.
Testing JNDI ... skipped.
Testing JSR-160 Edit ... skipped.
Testing HTTP ... success.
Testing Server MBeans Model ... skipped.
Testing HTTP Authentication ... success.

I went into OS X System Preferences and set my Computer Name to something other than MacBook Pro. I also clicked the Edit button there and set my Local Hostname: to the same value.

Also, check your /etc/hosts file for the proper alias, e.g. hostname.local

I had no more issue with JDeveloper connecting to an Application Server.

RCU-6016:The specified prefix already exists

I was running RCU via command line as part of a silent installation, and the script threw an exception while doing it's thing. I reran RCU via command line to drop the repository; however, it too threw an exception. So, I connected to the DB and removed the schemas manually. When RCU was executed again to create the schemas, another exception was thrown:

RCU-6016:The specified prefix already exists.
RCU-6091:Component name/schema prefix validation failed.

I reconnected to the database and manually created the schemas that RCU creates automatically. I was then able to successfully run RCU to drop and recreate the schemas.

As a side note, some RCU components create additional schemas that are not advertised. Case in point, the IAU component creates the following schemas:

${prefix}_IAU
${prefix}_IAU_APPEND
${prefix}_IAU_VIEWER

Linux sed Replace with Environment Variable Containing Path

I had a use case to construct a bash script to search a configuration file and replace a string with a path. This path was stored as an environment variable.

PATH=/some/path
export PATH

My original sed command looked like this:

sed -i "s/findThis/$PATH/g" someFile.cfg

Execution of the script kept throwing the following exception:

sed: -e expression #1, char 33: unknown option to `s'

After some trial and error, I discovered that the issue was related to the file separators (/) in the value of PATH. Instead of using a '/' as the separator for sed, use a pipe '|'.

sed -i "s|findThis|$PATH|g" someFile.cfg
