Splitting and Concatenating a 1-D Array

Hello,
I have a 1-D array of numbers and I am trying to split the 1-D array and then contanenate into a new 1-D array.
I am taking three sets of data from the original 1-D array and then forming the new concatenated array with what should be a space in between.
What I am finding is that the final concatenated 1-D array is empty.
Also I think I am using the incorrect spacer between the three data sets. I'm usinga 1-D array of noughts and really what I what I want is to create 1 column of noughts.
The .vi is attached.
Thanks for helping.

Thanks, your right. It can concatanate inputs. And yes, I should read the descriptions!!!
So what I have now is the three data sets concatanated but there is no space between them.
I have tried to make a zero data point as you can see from the .vi but non appears beacause it is an empty number.
I've tried to pull a zero onto the constant but it reverts back to shaded meaning it cannot be entered. Is there a way around this?
Addendum. Thinking is too complicated. I just used a zero numeric constant and that has solved it!!!

StringTokenizer vs. split and empty strings -- some clarification please?

Hi everybody,
I posted a question that was sort of similar to this once, asking if it was best to convert any StringTokenizers to calls to split when parsing strings, but this one is a little different. I rarely use split, because if there are consecutive delimiters, it gives empty strings in the array it returns, which I don't want. On the other hand, I know StringTokenizer is slower, but it doesn't give empty strings with consecutive delimiters. I would use split much more often if there was a way to use it and not have to check every array element to make sure it isn't the empty string. I think I may have misunderstood the javadoc to some extent--could anyone explain to me why split causes empty strings and StringTokenizer doesn't?
Thanks,
Jezzica85

Because they are different?
Tokenizers are designed to return tokens, whereas split is simply splitting the String up into bits. They have different purposes
and uses to be honest. I believe the results of previous discussions of this have indicated that Tokenizers are slightly (very
slightly and not really meaningfully) faster and tokenizers do have the option of return delimiters as well which can be useful
and is a functionality not present in just a straight split.
However. split and regex in general are newer additions to the Java platform and they do have some advantages. The most
obvious being that you cannot use a tokenizer to split up values where the delimiter is multiple characters and you can with
split.
So in general the advice given to you was good, because split gives you more flexibility down the road. If you don't want
the empty strings then yes just read them and throw them away.

Can we split and fetch the records in Database Adapter

Hi,
I designed a Database Adapter to fetch the records from oracle Database. Some time, the Database Adapter need to fetch around 5000, or 10,000 records in single shot. In that case my BPEL process is choking and getting error as
java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100)
Could someone help me to resolve this?
In Database Adapter can we split and fetch the records, if number of records more then 1000.
ex. First 100 rec as one set and next 100 as 2nd set like this.
Thank you.

You can send the records as batches useing the debatching feature of db adapter. Refer documentation for implementation details.

Splitting and grouping of data from incoming string

Hello,
I have a package of data coming from the serial port and read out as a string.
The package has the following format, to be short.
1. opening characters
2. 2 bytes for Group ID(identify the device# the data comes from).
3. Sensors data belongs to device# (1 byte each)
-data of sensor #1
-data of sensor #2
-data of sensor #3
-data of sensor #4
and loop back to sensor 1,2,3,4 for 20 bytes total.
I have eliminated the opening characters with the replace substring with empty string. For the Group ID, I used a case structure to identify which device it is. For the sensor data, I need to split them up and group all the data of the sensors together. I tried using substring for each sensor in a for loop that loop 5 times to group the data of each sensor together but it only give me the very last values.
My goal is to be able to extract and group the 5 bytes of each sensor together everytime the serial package comes in and then save them to a separte files for each sensor. I also want to be able to plot the data of each sensor as they come in with respect to time.
Any idea on how I can accomplish the grouping of data described above? I really appreciate your prompt response. Thanks,

Since you already know how to separate the sting containing the sensors data, you just have to use a string to byte function and to decimate the resulting array, as shown in the attached vi.

A subscript must be 1 and the size of the array

Hi Experts,
When I'm trying to run the report I'm getting the error, "a subscript must be 1 and the size of the array". Below is the formula.
Split({@newproj},",")[1]
Can anyone help me in identifying what went wrong???
Thanks in Advance,
Samrat Muddasani

Hi Samrat,
Looks like the formula : {@newproj}, is blank.
Try this:
If {@newproj} = "" then
else
Split({@newproj},",")[1]

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Unicode export:Table-splitting and package splitting

Hi SAP experts,
I know there are lot of forums related to this topic, but I have some new questions and hence posting a new thread.
We are in the process of doing unicode conversion in our landscape(CRM 7.0 system based on NW 7.01) and we are running on AIX 6.1 and DB2 9.5. The database size is around 1.5 TB and hence, we want to go in for optimization for export and import in order to reduce the downtime.As a part of the process, we have tried to do table-splitting and parallel export-import to reduce the downtime.
However, we are having some doubts whether this table-splitting has actually worked in our scenario,as the export has exeucted for nearly 28 hours.
The steps followed by us :
1.) Doing the export preparation using SAPINST
2.) Doing table splitting preparation, by creating a table input file having entries in the format <tablename>%<No.of splits>.Also, we have used the latest R3ta file and the dbdb6slib.o(belonging to version 7.20 even though our system is on 7.01) using SAPINST.
3.) Starting with the export using SAPINST.
some observations and questions:
1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
2.) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th split. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
3.) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
4.) Also, what exactly is the difference between table-splitting and package-splitting? Are they both effective together?
If you have any questions and or need any clarifications and further inputs, please let me know.
It would be great, if we could get any insights on this whole procedure, as we know a lot of things are taken care by SAPINST itself in the background, but we just want to be certain that we have done the right thing and this is the way it should work.
Regards,
Santosh Bhat

Hi,
First of all please ignore my very first response ... i have accidentally posted a response to some other thread...sorry for that
Now coming you your questions...
> 1.) Can package splitting and table-splitting be used together? If yes or no, what exactly is the procedure to be followed. As I observed that, the packages also have entries of the tables that we decided to split. So, does package splitting or table-splitting override the other, and only one of the two can be effective at a time?
Package splitting and table splitting works together, because both serve a different purpose
My way of doing is ...
When i do package split i choose packageLimit 1000 and also split out the tables (which i selected for table split) into seperate package (one package per table). I do it because that helps me to track those table.
Once the above is done i follow it up with the R3ta and wheresplitter for those tables.
Followed by manual migration monitor to do export/import , as mentioned in the previous reply above you need to ensure you sequenced you package properly ... large tables are exported first , use sections in the package list file , etc
> 2.) If you are well versed with table splitting procedure, could you describe maybe in brief the exact procedure?
Well i would say run R3ta (it will create multiple select queries) followed by wheresplitter (which will just split each of the select into multiple WHR files) ...
Best would go thought some document on table spliting and let me know if you have specific query. Dont miss the role of hints file.
> 3.) Also, I have mentioned about the version of R3ta and library file in my original post. Is this likely to be an issue?Also, is there a thumb rule to decide on the no.of splits for a table.
Rule is use executable of the kernel version supported by your system version. I am not well versed with 7.01 and 7.2 support ... to give you an example i should not use 700 R3ta on 640 system , although it works.
>1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
If you ask for 10 split .... you will get 10 splits or in some case 11 also, the reason might be the field it is using to split the table (the where clause). But not 100% sure about it.
> 2) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record.

Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
Not sure why you got 29 split when you asked for 36, one reason might be the field (key) used for split didn't have more than 28 unique records. I dont know how is PRCD_CLUST split , you need to check the hints file for "key". One example can be suppose my table is split using company code, i have 10 company codes so even if i ask for 20 splits i will get only 10 splits (WHR's).
Yes the 29th file will always have less records, if you open the 29th WHR you will see that it has the "greater than clause". The 1st and the last WHR file has the "less than" and "greater than" clause , kind of a safety which allows you to prepare for the split even before you have downtime has started. This 2 WHR's ensures that no record gets missed, though you might have prepared your WHR files week before the actual migration.
> 3) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
Not aware any thumb rule. First iteration you might choose something like 10 for 50 GB , 20 for 100 GB. If any of the tables overshoots the window. They you can give a try by increase or decrease the number of splits for the table. For me couple of times the total export/import time have improved by reducing the splits of some tables (i suppose i was oversplitting those tables).

Neel

1:n Message split and Abap Proxies??

Hello,
Can I not use Message split and Abap Proxy together? My scenario is MDM->File ->XI->Proxy->BI.
I am getting a single file syndicated from MDM and in XI If I use message mapping to do 1:n split in the message mapping, can I use it with Abap Proxies? As per the link below, XI adapter is not present in the list..We are on PI 7.0 SP14. Thank you..
http://help.sap.com/saphelp_nw04/helpdata/en/42/ed364cf8593eebe10000000a1553f7/frameset.htm
Thank you for any suggestion..

Hi Thanujja,
If you see the message from Raj, I dont think we can split the messages for the proxy. This is beacause the splitting of messages take place at the Adapter Level only for the adapters on the Java stack.
As suggested by Guru, you can try splitting the messages in the inbound proxy instead of using a BPM, in that way you can acheive good performance.
Thanks,
Srini

BPM Split and Merge

Hi...
I want to do scenario like file split and merge using BPM.
for that i have used,
1.Receive
2.Transformation(1:N)
3.Block(ForEach)
4.Control
5.EndBlock
6.Transformation(N:1)
7.Send.
while executing the scenario, the message is going to the queue. In that it is showing the status as "Running".
can you please tell if i did wrong in my scenario?

> 1.Receive
> 2.Transformation(1:N)
> 3.Block(ForEach)
> 4.Control
> 5.EndBlock
> 6.Transformation(N:1)
> 7.Send.
U are using an empty infinite block and hence it is in running state always. You dont need a block at all. after 1:n transformation, use the n:1 transformation and send. I know you must be doing a sample scenario. In reality you will have a send step usually for sending to another system line by line. That when you will need a block.

How to read a string character by character and pass it into an array

Hi,
I have a requirement to write a function.The thing is,i need to read string,replace space with a NULL,return in the form of an arrayy.
for this what i thought is,if the character is not a space,i need to put that into array,if its space,put a NULL for that.
the string is of type varchar2.
ex:XX XX XX
i need some suggestions for this.
thanks

Well, you can just use a loop that runs for the length of the string.
Then for each iteration of the loop, take the next character of the string (substr or similar) and add it to the array. If it's a space, then add a NULL to the array (if that's what you want).
Easy :)

Splitting and Collecting Messages

Hi,
I have a scenario in which I get a message from SAP. In this message their are multiple item structures and 1 header structure. Now I have to sent these items to a WS seperately and collect the messages from the WS response in one message with a header.
Something like:
Receive Message -> split message (message mapping) -> send all to WS / receive response for everyone -> collect messages from response in a new message -> send the new message to another WS
How can I do this in BPM?

Hi Chris,
Your design should be like this:
Start --> Receive --> Transform1 (Do the split and multimapping) --> Send Step1 (Synchronous) --> Send 2 (Send Response from send1 to the output) --> Stop.
