DB2 FOR LUW / DB2FORLUW / 950 - DB2

JCC driver throws the exception if fails to convert character. 
A typical scenario is some application using 
"ResultSet.getString" method to retrieve character strings from 
database and there are invalid characters in the string. 
 
By default, JCC driver uses "sun.io.*" methods to manipulate 
character strings. According to the standards for ""sun.io", it 
should throw the exception when fails to convert character 
strings (e.g. invalid characters that can not be converted). 
 
In the fix of the APAR, JCC driver introduces a global property 
named "db2.jcc.charsetDecoderEncoder" of type integer which 
could be set as follows: 
=========================================== 
1: 
   This is the default. 
   "sun.io.ByteToCharConverter" and/or 
"sun.io.CharToByteConverter" will be used if following classes 
could be loaded successfully: 
   -- sun.io.ByteToCharConverter 
   -- sun.io.CharToByteConverter 
   -- sun.io.MalformedInputException 
   -- sun.io.ConversionBufferFullException 
   -- sun.io.UnknownCharacterException 
   "java.nio.charset.CharsetDecoder" and/or 
"java.nio.charset.CharsetEncoder" will be used with 
"java.nio.charset.CodingErrorAction.REPORT" otherwise. 
 
2: 
   "java.nio.charset.CharsetDecoder" and/or 
"java.nio.charset.CharsetEncoder" will be used with 
"java.nio.charset.CodingErrorAction.REPORT". 
 
3: 
   "java.nio.charset.CharsetDecoder" and/or 
"java.nio.charset.CharsetEncoder" will be used with 
"java.nio.charset.CodingErrorAction.REPLACE". 
 
not defined or any other values: 
   The default value will be used. 
=========================================== 
 
To avoid the exception, you need to specify value 3 for the 
global property "db2.jcc.charsetDecoderEncoder". By this way, 
JCC converts invalid characters to NULL instead of throwing 
exceptions, using "java.nio.charset.CodingErrorAction.REPLACE" 
in case of error. 
 
You can add following line into your Java property file if you 
already have one: 
    db2.jcc.charsetDecoderEncoder=3 
or 
    specify "-Ddb2.jcc.charsetDecoderEncoder=3" on Java command 
line.

Fixed in DB2 V9.5 Fix Pack 8 JDBC driver.

Remove invalid characters from the string stored in database.

Upgrade the JDBC drivers to DB2 V9.5 Fix Pack 8 or above.
