MAX_VARIABLE_SIZE

[Eoin Collins]

I've run into issue where a REST WebService job returns a very large payload. I want to store this in an XML Vara but I get the following error:

U00020821 Runtime error in object '***', line '00000': Value of paramter '3' too long. Allowed length is '1048576' because of system setting MAX_VARIABLE_SIZE.

I wasnt able to find the setting MAX_VARIABLE_SIZE so I tried adding it too UC_SYSTEM_SETTINGS and increasing it, but it doesnt seem to have made a difference. Job is still failing with the same error, with

Allowed length is '1048576'

Has anyone come across this, and know if this setting can be changed, and if so, how?

[Pete Wirfs]

I used Agent Ransack to look for this setting, hoping to find it in a CONFIG or INI file.  All it found was 4 references inside of UCSJ.DLL, and this message which occurs frequently in our WP log files;

20170217/160017.391 - U00011847 'MAX_VARIABLE_SIZE' set to '001048576'.

So I don't see that this value can be modified?

The max value for MAX_VARIABLE_SIZE is 1 MB and cannot be increased.
Can you limit the output by either using:

• XPath
• XQuery
• JSONPath
• JSON to XML and XQuery

Or Groovy?

Thank you both. It seems my best option is to filter the response at the WebService level, so I do not run into this constraint in Automic

Message U00020821 mentions MAX_VARIABLE_SIZE:

U00020821

Runtime error in object '&01', line '&02': Value of paramter '&04' too long. Allowed length is '&05' because of system setting MAX_VARIABLE_SIZE.

No explanation of MAX_VARIABLE_SIZE appears in the documentation.

[Michael A. Lowry]

Broadcom Support provided additional details. MAX_VARIABLE_SIZE will be documented in a future update to the documentation.

MAX_VARIABLE_SIZE

Determines the maximum size of script variables in bytes.

Allowed values: 1024 to 1048576

Default value: 1048576

Restart required: No

I confirmed the lower and upper limits by setting MAX_VARIABLE_SIZE in UC_SYSTEM_SETTINGS to different values.

U00011831 Value: '1048577' for 'UC_SYSTEM_SETTINGS' / 'MAX_VARIABLE_SIZE' exceeds maximum. Maximum value: '0001048576' will be used.
U00011832 Value: '200' for 'UC_SYSTEM_SETTINGS' / 'MAX_VARIABLE_SIZE' is below the minimum value. Minimum value: '0000001024' will be used. 

I updated my AE Limits thread.
