Inserting a decimal which has no decimal into the table with a decimal point

Tom Kyte - Fri, 2016-07-22 14:46
Hi Tom, I want to insert a decimal number which has no decimal point into a table with a decimal point. Is there a predefined function or a way to do this? Ex: (46926831654) should be inserted as (469268.31654) I dont want to use the string...

APEX IDE for Shakespeare Programming Language (SPL)

Tony Andrews - Fri, 2016-07-22 08:04
Recently I came across an esoteric programming language called The Shakespeare Programming Language (SPL) and become rather fascinated by it.  It's big, and it's clever, but it's not terribly useful or practical.  But this year is the 400th anniversary of Shakespeare's death, which adds some relevance I suppose. Here is an example of an SPL program taken from the SPL docs.  All it does is Tony Andrewshttp://www.blogger.com/profile/16750945985361011515noreply@blogger.com0http://tonyandrews.blogspot.com/2016/07/apex-ide-for-shakespeare-programming.html

VirtualBox 5.1.2

Tim Hall - Fri, 2016-07-22 07:31

You know a major new release is going to be rapidly followed by a bunch of fixes, so about 9 days after the release of VirtualBox 5.1 we now have VirtualBox 5.1.2.

I have got it running on my Windows 7 desktop and work and it seems fine. I’ll try OSX El Crapitan and Oracle Linux 6 hosts when I get home.

Cheers

Tim…

Update: Works fine on Mac (El Craptian) and Oracle Linux 6 hosts too.

VirtualBox 5.1.2 was first posted on July 22, 2016 at 1:31 pm.

Dynamic Java in PeopleCode

Jim Marion - Fri, 2016-07-22 04:06

The PeopleCode language has a lot of features and functions. But sometimes, it seems there are tasks we need to accomplish that are just out of reach of the PeopleCode language. It is at these times that I reach for Java. I have written a lot about Java, so I'm sure many of you already know how to mix Java with PeopleCode. While certainly a rational solution, one of the pain points of a Java solution is managing custom Java on the app and process scheduler servers. Each time you update your compiled class (or jar) files, you have to restart the server. That might be OK in a stable production environment, where you don't intend to change code often, but in development, it is a real pain! Likewise, maintaining custom Java class and jar files through upgrades can be a little sketchy. Specifically, if you redeploy PeopleTools or rewrite psconfig, then it is possible you may miss some of your custom Java code. PeopleBooks tells us how to setup psconfig for custom Java classes, but again, that is just one more thing to manage through upgrades. Now, imagine being able to update your custom Java code with a Data Mover script. Further, imagine being able to run custom Java without making any changes to your application server. Imagine what it would be like to run Java without having to beg (or bribe) your admin for a "no customization" exception. It is possible today. The answer: Use JavaScript to interface between PeopleCode and the delivered Java Runtime Environment. Through the embedded Mozilla Rhino JavaScript script engine of Java, we have full, dynamic access to the JRE. When and how would you use this? Let's review some examples.

Custom HTTP Connections

For various reasons, some customers choose not to implement Integration Broker. These customers find themselves requiring integration, but without IB's networking features. An alternative to %IntBroker.ConnectorRequestURL is to use Java's HttpURLConnection.I strongly discourage this approach, but the question arises. The JRE is there, well integrated with PeopleCode, and ready for use. From PeopleCode, it is possible to create a Java URLConnection using CreateJavaObject("java.net.URL", "http...").openConnection(). A problem arises when we try to invoke methods of a HttpURLConnection, the real return value of URL.openConnection. Unfortunately, PeopleCode doesn't see it that way, which leads down the reflection path (we don't want to go there). This is where JavaScript can help us. JavaScript doesn't mind that URL.openConnection returned an HttpURLConnection even though it said it would just return a URLConnection. Here is an example:


var result = (function() {
// declare pointers to Java methods to make it easier to invoke the methods
// by name later
var URL = Packages.java.net.URL;
var InputStreamReader = Packages.java.io.InputStreamReader;
var BufferedReader = Packages.java.io.BufferedReader;
var StringBuilder = Packages.java.lang.StringBuilder;

var serverAddress = new URL(
"http://hcm.oraclecloud.com/hcmCoreApi/atomservlet/employee/newhire"
);


// Creates an HttpURLConnection, but returns URLConnection. If I was using
// PeopleCode, PeopleCode would see this as a URLConnection. To invoke
// HttpURLConnection methods, I would need to resort to reflection. This is
// the power of JavaScript in this scenario...
var connection = serverAddress.openConnection();

// ... for example, setRequestMethod is NOT a method of URLConnection. It is
// a method of HttpURLConnection. PeopleCode would throw an error, but
// JavaScript recognizes this is an HttpURLConnection and allows the method
// invocation
connection.setRequestMethod("GET");

// Timeout in milliseconds
connection.setReadTimeout(10*1000);

// Finally, make the connection
connection.connect();

// Read the response
var reader = new BufferedReader(
new InputStreamReader(connection.getInputStream()));
var sb = new StringBuilder();
var line;

while ((line = reader.readLine()) !== null) {
sb.append(line + '\n');
}

// Return the response to PeopleCode. In this case, the response is an XML
// string
return sb;
}());

Excel Spreadsheets

PeopleTools 8.55+ has a PeopleCode API for Excel, which means this solution is now irrelevant. I'm listing it because not everyone is up to PeopleTools 8.55 (yet). If you use this idea to build a solution for 8.54 and later upgrade, Oracle recommends that you switch to the PeopleCode Excel API. The solution will still work with 8.55+, but just isn't recommended post 8.54.

This solution uses the Apache POI library that is distributed with PeopleTools 8.54+ to read and write binary Microsoft Excel files. As with the networking solution above, it is possible to use POI directly from PeopleCode, but a little difficult because POI uses method overloading in a manner that PeopleCode can't resolve. Furthermore, POI uses methods that return superclasses and interfaces that PeopleCode can't cast to subclasses, leading to awful reflection code. Here is an example that reads a spreadsheet row by row, inserting each row into a staging table for later processing.


// endsWith polyfill
if (!String.prototype.endsWith) {
String.prototype.endsWith = function(searchString, position) {
var subjectString = this.toString();
if (typeof position !== 'number' || !isFinite(position) ||
Math.floor(position) !== position ||
position > subjectString.length) {
position = subjectString.length;
}
position -= searchString.length;
var lastIndex = subjectString.indexOf(searchString, position);
return lastIndex !== -1 && lastIndex === position;
};
}

// open a workbook, iterate over rows/cells, and then insert them into a
// staging table
var result = (function() {
// declare pointers to Java methods to make it easier to invoke the methods
// by name
var FileInputStream = Packages.java.io.FileInputStream;

var HSSFWorkbook = Packages.org.apache.poi.hssf.usermodel.HSSFWorkbook;
var Workbook = Packages.org.apache.poi.ss.usermodel.Workbook;
var XSSFWorkbook = Packages.org.apache.poi.xssf.usermodel.XSSFWorkbook;

// declare a PeopleCode function
var SQLExec = Packages.PeopleSoft.PeopleCode.Func.SQLExec;

// internal "helper" function that will identify rows inserted into
var guid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g,
function(c) {
var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8);
return v.toString(16);
}
);

// open a binary Microsoft Excel file
var fis = new FileInputStream(fileName);

var workbook;

if(fileName.toLowerCase().endsWith("xlsx")) {
workbook = new XSSFWorkbook(fis);
} else if(fileName.toLowerCase().endsWith("xls")) {
workbook = new HSSFWorkbook(fis);
}

var sheet = workbook.getSheetAt(0);
var rowIterator = sheet.iterator();
var roleName,
descr,
row;

// iterate over each row, inserting those rows into a staging table
while (rowIterator.hasNext()) {
row = rowIterator.next();
roleName = row.getCell(0).getStringCellValue();
descr = row.getCell(1).getStringCellValue();

// TODO: turn this into a stored SQL definition, not hard coded SQL
SQLExec("INSERT INTO PS_JM_XLROLE_STAGE VALUES(:1, :2, :3, SYSTIMESTAMP)",
// notice that the SQLExec parameters are wrapped in an array
[guid, roleName, descr]
);
}

// return the unique identifier that can later be used to select the rows
// inserted by this process
return guid;

}());

Here is an example of writing/creating a Microsoft Excel spreadsheet:


var result = (function() {
// import statements
var XSSFWorkbook = Packages.org.apache.poi.xssf.usermodel.XSSFWorkbook;
var FileOutputStream = Packages.java.io.FileOutputStream;

// variable declarations
var workbook = new XSSFWorkbook();
var sheet = workbook.createSheet("Countries");
var fileName = "c:/temp/countries.xlsx";

var row = sheet.createRow(0);
var cell = row.createCell(0);

cell.setCellValue("United States of America");
cell = row.createCell(1);
cell.setCellValue("USA");

row = sheet.createRow(1);
cell = row.createCell(0);
cell.setCellValue("India");
cell = row.createCell(1);
cell.setCellValue("IND");

row = sheet.createRow(1);
cell = row.createCell(0);
cell.setCellValue("Denmark");
cell = row.createCell(1);
cell.setCellValue("DNK");

var fos = new FileOutputStream(fileName);
workbook.write(fos);
fos.close();

return "Created workbook " + fileName;

}());

JSON Parsing

If your goal is to convert a JSON string into SQL insert statements, then this is a very painless alternative:


/* Sample JSON data that will be selected from a record definition
[
{"emplid": "KU0001", "oprid": "HCRUSA_KU0001"},
{"emplid": "KU0002", "oprid": "HCRUSA_KU0002"},
{"emplid": "KU0003", "oprid": "HCRUSA_KU0003"}
];*/

var result = (function() {
var CreateRecord = Packages.PeopleSoft.PeopleCode.Func.CreateRecord;
var Name = Packages.PeopleSoft.PeopleCode.Name;
var SQLExec = Packages.PeopleSoft.PeopleCode.Func.SQLExec;

// example of how to reference a PeopleCode record definition from
// JavaScript. Later we will select JSON_DATA from this table
var rec = CreateRecord(new Name('RECORD', 'NAA_SCRIPT_TBL'));

var count = 0;
var json_string;
var json;

var guid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8);
return v.toString(16);
});

// Select JSON string from a table. Normally this would come from a variable,
// a service, etc. Here it makes a great example of how to select rows from
// a record definition
rec.GetField(new Name('FIELD', 'PM_SCRIPT_NAME')).setValue('JSON_TEST_DATA');
rec.SelectByKey();
json_string = rec.GetField(new Name('FIELD', 'HTMLAREA')).getValue();

// now convert that received string into an object.
json = JSON.parse(json_string);

// Iterate over json data and...
json.forEach(function(item, idx) {
// ... insert into a staging table
SQLExec("INSERT INTO PS_NAA_TEST_TBL VALUES(:1, :2, :3, SYSTIMESTAMP)",
// notice the array wrapper around SQLExec bind values
[guid, item.emplid, item.oprid]
);
count += 1;
});

return "Inserted " + count + " rows";

}());

I could go on and on with examples of creating zip files, encrypting information, base64 encoding binary data, manipulating graphics using Java 2D, etc, but I think you get the idea.

GoldenGate 12.2 TROUBLESHOOTING USING GETENV

Michael Dinh - Thu, 2016-07-21 21:14

I was faced with a very strange situation.

When using SETENV (ORACLE_SID = db01), replicat ABEND with  OGG-00664  OCI Error beginning session (status = 1034-ORA-01034: ORACLE not available

When using SETENV (ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/dbhome_1), replicat starts without any issues.

I know what you are thinking, why not set both ORACLE_SID and ORACLE_HOME and you are correct since this is best practices.

The client already knows this and wanted to troubleshoot why it was failing?

Any ideas? I scoured the internet and MOS and finally found that using get_env was the key to troubleshooting.

Tried tracing the replicat and did not work since replicat abended.

NOTE:  Environment variables are all set correctly from the OS.

BAD:
REPLICAT R_2D2
SETENV (ORACLE_SID = db01)

getenv (ORACLE_HOME)
ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/dbhome_1

getenv (ORACLE_SID)
ORACLE_SID = b01
USERIDALIAS ggadmin

2016-07-21 18:33:46 ERROR OGG-00664 OCI Error beginning session (status = 1034-ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory).
GOOD:
REPLICAT R_2D2

SETENV (ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/dbhome_1)

getenv (ORACLE_HOME)
ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1

getenv (ORACLE_SID)
ORACLE_SID = db01
USERIDALIAS ggadmin

Notice, there are 2 different ORACLE_HOMEs being used.

Bad one is ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/dbhome_1 since the HOME does not exists.

Wait a minute, how is it possible the HOME does not exists and where did Goldengate get this information ???

Let’s find the installation log.
/u01/app/oraInventory/logs> grep "MANAGER_PORT" installActions2016*.log|uniq

There it is, Goldengate is using ORACLE_HOME defined from the installation.

DATABASE_LOCATION is not required, so why set it?

Admittedly, I have have been setting DATABASE_LOCATION but will not be doing so any more.

#-------------------------------------------------------------------------------
# Specify the location of the Oracle Database.
# Required only if START_MANAGER is true.
#-------------------------------------------------------------------------------
DATABASE_LOCATION=

Lastly, I have not attempted to reproduce the error. Too lazy. May be you can help?
