No data found exception using oracle olapi

i started experimenting with oracle olap api 'olapi', but i'm having some issues while running their examples package.
when i run MakingQueriesExamples.java in source package i get this error:

i'm using oracle database 11.2.0.1.0 with OLAP option enabled and oracle analytical workplace manager 11.2.0.4B
i've started by installing the 'global' schema as instructed here:
https://www.oracle.com/technetwork/database/options/olap/global-11g-readme-082667.html
i verified everything in AWM (cubes, dimensions and mesures), and the data in sqldevelopper.
i've noticed that some of the hierarchies' names have changed so i updated them on the java code
any help would be appreciated !
thanks in advance

Data truncation error while setting INOUT parameter in Stored Procedure

I'm calling a stored procedure which has INOUT parameters. Database is AS400 DB2. Type is CHARACTER. I'm getting Data Truncation error while registering and setting the variable. If I set the string directly to the column, it does not have an issue. If I set the same string in a variable and use it to set the column, it throws Data truncation error. Could you please let me know where I'm going wrong and how I can set the value of the column using a variable without causing exception? Please see the end of error stack trace for more information.
try{
String cstmt_str = "CALL " + storedProcName + "(?)";
String status="REJ";
cstmt = conn.prepareCall(cstmt_str);
cstmt.registerOutParameter("5506STS", Types.CHAR);
//cstmt.setString("5506STS","REJ"); does not give a problem
cstmt.setString("5506STS",status); //Data truncation Exception occurs here.
cstmt.execute();
}catch (DataTruncation de) {
logger.error("DatatruncationException error:", de );
displayError(de);
de.printStackTrace();
}
public static void displayError(DataTruncation dataTruncation) {
logger.info("Data truncation error: ");
logger.info("dataTruncation.getDataSize():"+dataTruncation.getDataSize() + " number of bytes of data that should have been transferred.");
if (!dataTruncation.getRead())
logger.info("dataTruncation.getRead() is False. Its Written (Error:). ");
logger.info("dataTruncation.getTransferSize():"+dataTruncation.getTransferSize()
+ " number of bytes of data actually transferred.");
}
Stored Procedure Signature:
Number Mode Name DataType Length
1 INOUT 5506STS CHARACTER 3
I tried to find out the length of the string status:
int len = status.getBytes().length; // Output: 5
I'm out of options. Please let me know how to successfully set the value in the variable "status" into "5506STS".

Well, I found it out myself. The "status" that was passed to the function had a single quote surrounding it.('APP') this made the length 5 instead of 3. Now I removed the single quotes.Its working fine.

Reduce memory usage in java

I have a web service Java program which reads 13,000,000 dates like '08-23-2016 12:54:44' as strings from database. My developing environment is Java 8, MySQL 5.7 and tomcat 8. I have declare a string array String[] data to store it. I use Guice to inject the initial values of data array to empty. However, the memory usage is still huge. This is my code:
String[] data;//size is 1,000,000
void generateDataWrapper(String params) {
//read over 13000000 dates string
ResultSet rs = mySQLCon.readData(params);
clearData(data);//set to empty string
int index = 0;
while(rs.next()) {
data[index++] = rs.getString("date");
if (index == (size - 1)) {//calculate every 1,000,000 total 13 times
//calculate statistics
...
//reset all to empty string
clearData(data);
index = 0;
}
}
}
//mySQLCon. readData function
ResultSet readData(String params) {
try {
String query = generateQuery(params);
Statement postStmt = connection.createStatement();
ResultSet rs = postStmt.executeQuery(query);
return rs;
} catch (Exception e) {
}
return null;
}
If I call this function once, the memory is reached 12G, If I call it again, the memory goes to 20G, on the third time the memory will goes to 25G and throw a 'java.lang.OutOfMemoryError: GC overhead limit exceeded' error in com.mysql.jdbc.MysqlIO.nextRowFast(MysqlIO.java:2174)
This is part of the error message:

I have changed the garbage collection algorithms to:
-XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode
But it's not helping.
I have tried change the data to static variables, still will have this problem.
Currently the JVM heap is 8g, the tomcat memory is 24g, however, I don't think increase the memory will solve the problem.
I don't understand why my memory is still increasing every time I call this function, Could someone give me some suggestion?

Used resources like a ResultSet have to be closed to release the underlying system-resources. This can be done automatically declaring the resources in a try-block like try (ResultSet resultSet =...).
You can try to fetch only a limited number of rows from database when they are requested from ResultSet and not all of them immediately.
Objects get eligible for garbage collection when they are not referenced any more. So, your array-object keeps in memory with it's whole size as long as it is referenced. If it's not referenced any more and the VM is running out of memory it will be able to dispose the array-object possibly avoiding an OutOfMemoryError.
Unexpectedly high memory usage can be analyzed by creating a heap dump and exploring it in the tool jvisualvm of the JDK.

Additionally you can change your string array to an long array since strings consume a huge amount of memory. In your case the size of a date string is 38 bytes ( 19 char * 2 bytes ) whereas a long only takes 8 bytes of memory.
long[] data;//size is 1,000,000
void generateDataWrapper(String params) {
//read over 13000000 dates string
ResultSet rs = mySQLCon.readData(params);
clearData(data);//set to empty string
int index = 0;
SimpleDateFormat formater = new SimpleDateFormat("MM-dd-YYYY HH:mm:ss");
while(rs.next()) {
try{
Date date = formater.parse(rs.getString("date"));
data[index++] = date.getTime();
}catch(ParseException pe) {
pe.printStackTrace();
}
if (index == (size - 1)) {//calculate every 1,000,000 total 13 times
//calculate statistics
...
//reset all to empty string
clearData(data);
index = 0;
}
}
}
Wherever you need your string you can just parse it back with the following
SimpleDateFormat formater = new SimpleDateFormat("MM-dd-YYYY HH:mm:ss");
Date date = new Date(data[i]);
String dateString = formater.format(date);

First, thanks for all your suggestions. I have figured this out by reading from mm759 and realized that I forgot to close the ResultSet after I have done reading. After I add rs.close(), every time it takes the same time to finish, although the memory will reach the maximum memory I set.

Out of memory Error when using scala to process some xml

I have broken wiki xml dump into many small parts of 1M and tried to clean it (after cleaning it with another program by somebody else)
I get an out of memory error which I don't know how to solve. Can anyone enlighten me?
I get the following error message:

Where line 234 is as follows:
writer.addDocument(document)
It is adding some documents to Lucene
and where line 224 is as follows:
for (doc <- target_xml \\ "doc") yield {
It is the first line of a for loop for adding various elements as fields in the index.
Is it a code problem, setting problem or hardware problem?
EDIT
Hi, this is my for loop:
for (knowledgeFile <- knowledgeFiles) yield {
System.err.println(s"processing file: ${knowledgeFile}")
val target_xml=XML.loadString(" <file>"+cleanFile(knowledgeFile).mkString+"</file>")
for (doc <- target_xml \\ "doc") yield {
val id = (doc \ "#id").text
val title = (doc \ "#title").text
val text = doc.text
val document = new Document()
document.add(new StringField("id", id, Store.YES))
document.add(new TextField("text", new StringReader(title + text)))
writer.addDocument(document)
val xml_doc = <page><title>{ title }</title><text>{ text }</text></page>
id -> xml_doc
}
}).flatten.toArray`
The inner loop just loops thru every doc element. The outer loop loops thru every file. Is the nested for the source of the problem?
Below is the cleanFile function for reference:
def cleanFile(fileName:String):Array[String] = {
val tagRe = """<\/?doc.*?>""".r
val lines = Source.fromFile(fileName).getLines.toArray
val outLines = new Array[String](lines.length)
for ((line,lineNo) <- lines.zipWithIndex) yield {
if (tagRe.findFirstIn(line)!=None)
{
outLines(lineNo) = line
}
else
{
outLines(lineNo) = StringEscapeUtils.escapeXml11(line)
}
}
outLines
}
Thanks again

Looks like you would like to try increasing the heap size by having -xmx jvm argument?

Storing an ordered List with JPA/Hibernate

On a Device a user can select the languages of preference in which the content is going to be showed. I have used this for a long time, but updated the system that this list is ordered:
#Required
#OrderColumn(name="preferenceOrder")
#ManyToMany(fetch= FetchType.LAZY)
public List<Language> languages;
But when I try to update the list with the following code:
try{
// Get the codes of the Device
Device device = Device.findById(deviceId);
device.languages.clear();
for(String langCode : languageCodes){
Language lang = Language.findByCode(langCode);
device.languages.add(lang);
}
device.save();
return true;
} catch (Exception e) {
Logger.error(e, "Problem with updating the languages for device: " + e.getLocalizedMessage());
return false;
}
I get the following error:

What is the reason for this?
I find 5 records, which is right is this case, but expects 1?
Is it because I first clear the whole list, and should I use another way? This is just the easiest for me to add them in the order they are given me.
