FIX: Transaction Integrator slow with large arrays of untranslated bytes in Host Integration Server

You define a parameter in a Transaction Integrator (TI) object as a byte array of untranslated bytes in Host Integration Server. If the byte array is very large (for example, more than 10,000 bytes), the call takes longer than when a similar call is made by using Host Integration Server 2010.

In Host Integration Server, there are added checks included for packing and unpacking data to allow for better error reporting. In the byte array, each byte is checked. When it is a large array, performance is decreased.

Because this is an untranslated byte array, there is no translation. Therefore, the additional error checking is not necessary. Transaction Integrator was changed to skip error checking for untranslated byte arrays.

The fix that resolves this problem is included in the following cumulative updates for Host Integration Server:

Cumulative Update 2 for Host Integration Server 2016

Cumulative Update 4 for Host Integration Server 2013
