How does a global variable affect the runtime of optimisation-function fminsearch?

Hi,
my function "fmintest" needs 254s ~ 4min to finish calculation in Mathscript, while Matlab needs
3s!!! I need the sorfware for data processing in a real time measuring system, where the calculation have to be done within 5 seconds.
In the Mathscript-help I found the following (global -> details):
If you call this function from a MathScript Node, LabVIEW operates with slower
run-time performance for the MathScript Node. To optimize the performance of the
MathScript Node, remove this function from scripts.
How can I remove needed global variables in the fminsearch function handle? Is the system faster if I would/can remove the global variables?
How can I avoid Mathscript-breakdown after saving changes to m-files and restarting them again?
regards

Hi,
can you provid a VI and not only your m-files? It will be easier to help you!
Can the customer provide a VI that demonstrates this behavior, rather than just providing the m files?
Also, the Help file says fminsearch is not supported by the
LabVIEW Run Time engine, so please take that in mind. If you want to build an application you cant use this function.

How to change Global variable in the query

Hi,
I have 6 reports which is using 0PDT as a global variable and has single option as a property. Now I want to change this property and have multiple selection but I am not able to change its property.
I am able to see all the filter variables from the query property and from there I am getting edit option to change but the "single selection" option is grey/disable which is preventing me to make change in this variable. Is there any way that I delete this variable and create a local variable which has date range option.
This is affecting all my reports and all the report needs date ranges instead of single select option.
Thanks,
Shivani

Shivani,
You can change the restrictions with new variable(right click on required infoobject and choose restrict -->> choose variables -->> move existing variable from right to left and move new variable. Then you can see only one variable.
You can not delete any variable if is using in some queries.
how to restrict:

How does a corrupted file affect the vault update?

If I would have updated the vault after the files got corrupted, wouldn't the corruption get updated as well? Wouldn't that defeat the purpose?

I believe it's meant to only copy files that it knows have changed.
I.e. old masters wouldn't get re-copied, but version updates, metadata changes, new imported masters would.
Of course, many people here reported having a lot of problems with the Vault mechanism in version 1, but others seem to have no problem at all (suggesting a subtle system configuration difference.)

Webdynpro - how to add global variables and common proj to existing proj

How to add global variable in either ViewController or CustomController. We realise that codes must be added within the begin and end exction. Codes outside that will be deleted when saved.
How can we add a common WDP project to an existing project? We have actually added a common wdp project at the project references screen. But during runtime, we encouter error. The error is classNotFoundException. The class is the class created in the common project.

Step1.
Open propety of ProjectA.
Step2.
Select WebDynproRefrences
Step3.
Select Sharing references
Step4.
Choose add button.

If your projectA named "testapp" and you are not using

I hope that it work!!!.

ABAP Program global variable print at runtime

Hi,
I have an abap program with more than 1000 global variables. I want to run the program and at a specific point show a report with names and runtime values of all the global variables in the program. Is there some system table which stores all the global variable names and source code? Kindly help.
Satya

Hello Satya,
You can store all your global variables in one internal table.
let's say your Itab contains 1000 fields. Now, if you want to retrive the name of the itab, you can use the system call.
DATA: IT_COMP LIKE RSTRUCINFO OCCURS 0 WITH HEADER LINE.
*-- Getting fields of internal table
CALL 'AB_STRUC_INFO'
    ID 'PROGRAM'   FIELD SY-CPROG
    ID 'STRUCNAME' FIELD P_ITAB
    ID 'STRUCINFO' FIELD IT_COMP-SYS.
After getting all your fields in it_comp table you can use field symbol to get the values of your fields.

ExportPDF is based on a newer conversion engine than the one found in Acrobat 9.0. They're similar in some respects, but ExportPDF is more advanced.

How to declare global variables using another global variable in ODI

I am declaring a gloabal variable using another global variable.
say for example:
I have a global variable empid.
I am decalaring another global variable empname in refreshing tab of global variables and the select statment is
select empname from emp where empno = #GLOBAL.empid -------if i write like this i am getting error as invalid character.
select empname from emp where empno = '#GLOBAL.empid'-------if i write like this i am getting error as invalid number.
I have kept the datatype as numeric and action as non persistent
Please help
Thank you in advance.

Hi,
You cant test/refresh empname standalone.
You need to create a new package drag and drop both variables and make them as refresh variable and execute that package and test.
Flow,
empid----> empname

I am not upset or unappreciative of your feedback, quite the opposite, I can't believe anyone actually monitors peoples frustrations.
I just want to make sure I don't allow information about me that is not necessary. I just want to listen to music and have a phone and have an ipad.

[Solved] How does one go about changing the hostname in arch nowadays?

Everything I've seen on the subject references /etc/rc.conf, which I believe is no longer used.
I've updated /etc/hostname, but when hostname -f does not return the expected.
