batch-processing

I have come across a big problem while testing my code. And this problem is the annoying message ... "Maximum recursion depth exceeded". Look how it works: @echo off REM ---------- MAIN MENU ---------- :Main echo 1.Supermarket echo 2.Exit Batch setlocal for /f %%A in ('"prompt $H & echo on & for %%B in (1) do rem"') do set "BS=%%A" set /p Menu=%BS% Type in your option {1,2} followed by ENTER: if not '%Menu%'=='' set Menu=%Menu:~0,1% if %Menu% EQU 1 ENDLOCAL & goto Super if %Menu% EQU 2 goto EOF REM ---------- SECONDARY MENU ---------- :Super echo 1.Supermarket echo a.Apple echo b.Banana

I have a large amount of csv files that I need in .xls format. Is it possible to run a batch conversion with a macro or best done with another language? I have used this code http://www.ozgrid.com/forum/showthread.php?t=71409&p=369573#post369573 to reference my directory but I'm not sure of the command to open each file and save them. Here's what I have: Sub batchconvertcsvxls() Dim wb As Workbook Dim CSVCount As Integer Dim myVar As String myVar = FileList("C:\Documents and Settings\alistairw\My Documents\csvxlstest") For i = LBound(myVar) To UBound(myVar) With wb Application.Workbooks

I am starting to learn HBase to write data streams. I use HTableInterface and having problem in performance. It took much times to insert only 500 rows, almost 500,000ms per batch List that I inserted. Any example or suggestion for batch write into HTable with HTableInterface ? I am using HBase 0.94 Thanks They're essentially the same: batch(List<? extends Row> actions, Object[] results) allows not only puts but also gets, deletes, increments... put(List<Put> puts) just do a batch of puts (it also validates them client-side). You can also perform batches by disabling table.setAutoFlush(false)

I have a java 1.6 application which use batch insert for inserting records in Oracle db using jdbc driver. As you know on Statement object there is a method called executeBatch() which we use for batch updates. It has a return type of int array which has result of execution for each record in it. But it also throws BatchUpdateException in case of error and we can get result int array from that too. My question is in what error situations I should expect BatchUpdateException and when I should expect there is no exception thrown but for some records I get failure. Note: Question is spesifically

I would like to use doctrine batch insert processing in order to optimize insert of a big amount of entities. The problem is with Clear method. It says that this method detach all entities that are managed by EntityManager. So what should I do in a situation where I have a parent Entity, which has many child, and each child has their childs, like this: riseSession track points So I have 1 rideSession, 3 tracks and each track has for isntance 2 000 points. I could use batch processing in last loop which is responsible for saving points. But if I use clear method, then how to set parents for

Programmatically configuring fault tolerance for a chunk works kind of as follows: stepBuilders.get("step") .<Partner,Partner>chunk(1) .reader(reader()) .processor(processor()) .writer(writer()) .listener(logProcessListener()) .faultTolerant() .skipLimit(10) .skip(UnknownGenderException.class) .listener(logSkipListener()) .build(); The trick is, that with adding "chunk", the chain switches to a SimpleStepBuilder which offers the "faultTolerant" method. My question is how to do that if you just have a tasklet (no reader, processor, writer)? Defining a tasklet works as follows: stepBuilders.get(
