Ice.MessageSizeMax

PeteH

Our C++ server includes Ice interfaces (Ice 3.2) with methods which could potentially return large strings to a ruby client. A typical interface might look like this:

interface Shipment
{
  ...
  idempotent string PDFReportSummary();
	...
};

Here, PDFReportSummary returns a base64 encoded PDF report which can exceed the 1024KB and if it does, the call fails.

According to the bible, the Ice.MessageSizeMax is set to 1024KB by default. I therefore thought all I needed to do was to set this property to a larger value in both, the C++ and the ruby Ice communicator.

In C++ I have this inside the startup code:

Ice::PropertiesPtr pProps = Ice::Application::communicator()->getProperties();
pProps->setProperty("Ice.MessageSizeMax", "65536");

In Ruby I do:

props = Ice.createProperties(ARGV)
props.setProperty("Ice.MessageSizeMax", "65536");

However, this does not appear to be making any difference as the method still fails if the size of the string exceeds 1MB.

What am I missing?

Hi Peter,

In C++ I have this inside the startup code:

Code:

Ice::PropertiesPtr pProps = Ice::Application::communicator()->getProperties();
pProps->setProperty("Ice.MessageSizeMax", "65536");

You should set this property before the communicator is initialized, setting the property after the communicator was initialized does nothing.

Cheers,

Hi Jose,

Since my startup code was based on Ice::Application I had little control over when and how the communicator was constructed.

Once I removed Ice::Application things started working fine.

Thanks for your help
