Thanks Jon. What I am doing now is loading a varchar field (rtndata) with the XML as it is being created using the %trim and then at LR time loading the courtcase parm with the contents of the varchar field (rtndata). This has greatly increased the throughput and won't include the length bytes in the parm. I am just overwhelmed as to how much faster the program runs by loading the varchar field instead of a fixed length field.
Thanks,

Change to varying length - IWS output will ignore the length bytes (which will be 4 by the way for a field of this length.
Just make sure that you build the field by trimming data into it when needed.
In other words:
courtcase += %Trimr(newData);

Here is the parameter list that is being interpreted incorrectly. The reason for not using the varchar is that a byte appears at the beginning of the field that I assume is the length of the varchar field in hex or binary and it becomes part of the output parameter which in my case the end-user does not want.

D WSCASEINQ PI
D CASE# 13A
D courtcase_LENGTH...
D 10i 0

This simple program accepts the CASE# parm and simply creates XML in the courtcase parameter. But since I don't know how large the XML will be at any given time I want to make the courtcase parameter large enough to store all XML that will be created.

Jon, you could use length fields for character fields. Some applications have character fields with large lengths, and IWS trims trailing blanks, and thus for these types of fields it could degrade performance.
However, I do agree that varchar would be much cleaner.

If you are not using an array how can the parameter vary in length?
If it is a character field and you want to restrict the output length
why not use a varying length field?

Have you enable "detect field lengths" option? Do you have
varchar would also work in this case as well.
FYI, the article was written prior to varchar[1] support.

Hi All,
We have found an article that addresses speeding up the SOAP web
service when large character fields are used to return data to the
consumer (titled: Integrated web services server for IBM i updates
website: https://www.ibm.com/developerworks/ibmi/library/i-
integrated-web-services-server/index.html ).
Below is an excerpt from the article:
Enable improved processing of very large output character fields
Length field support has been extended to character fields. Output
character fields that are very large (I am talking about 1000s of
bytes) take time to process because the determination of the size
of
sizethe string to return is done by traversing the field a byte at a
time, from right to left, looking for the first non-blank character.
To improve the processing of these large character fields, you can
specify an integer (int) field length that immediately precedes
the character field with the same name as the character field
appended with _LENGTH (similar to what is done when processing
output arrays with field lengths). If the field length exists and
Detect length fields is selected, the traversing of the field to
determine the
approachclient response.is not performed, improving performance. In addition, the length
field is hidden from the client and is not returned in the
My question to the group is - Has anyone tried using this approach?
I have coded my SOAP web service (I am the provider) using this
approach only to find that it does not work as outlined in the
article. I am running this on a v7.2 machine and it is written in
RPGLE as a program (not a service program).
When I perform the redeploy of the service all 3 parameters are
displayed (including the _LENGTH parm), but I was expecting only 2
parameters to appear (excluding the _LENGTH parm).
Here is the RPGLE code from my program:
D WSCASEINQ PR ExtPgm('WSCASEINQ')
D CASE# 13A
D courtcase_LENGTH...
D 10i 0
D courtcase 500000a
D WSCASEINQ PI
D CASE# 13A
D courtcase_LENGTH...
D 10i 0
D courtcase 500000a
The whole idea is to not return the _LENGTH parm to the consumer.
There is no example in the article, it just states that this
u=https-3A__lists.midrange.com_mailman_listinfo_web400&d=DwICAg&c=jf_iworks like the approach used for the array.66
Does anyone know what I am doing wrong to not be able to take
advantage of this approach? Any assistance is greatly appreciated.
