Tuxedo JSH Process High Memory Use Occurs When Receiving FML Buffer Containing A Zero Length CARRAY Field (Doc ID 2174359.1)

Last updated on JUNE 28, 2017

Applies to:

Oracle Tuxedo Jolt - Version 11.1.1.2.0 and later
Information in this document applies to any platform.

Symptoms

 Tuxedo JSH (a JOLT server handler) process high memory usage occurs when processing a Tuxedo FML/FML32 buffer which contain a zero length CARRAY field(that is to say, zero bytes defined).

An example of JOLT client code causing the excessive memory use is shown by the following:

String str = "";
dataset.setValue("binary_data",str.getBytes());
sessionPool.call("TOUPPER", dataset, null);

If the "str" object above has any characters/data assigned the memory problem does not happen when the Tuxedo TOUPPER service is called.
