Large bulk data transfers fail

(CR 471636) Bulk data transfers greater than 512 bytes fail when issued from versions of client applications 15.0 and later. Client applications version 15.0 and later use an increased packet size of 2048, which is currently not supported by the Sybase SNA network software. The transfer fails with this error:

VENDORLIB] Vendor Library Error: DB2 Access Module GWLib error (TDYNAMIC returned -80) <DB2>.

Workaround: Use client versions earlier than 15.0 to issue the bulk transfer command, or use a TCP/IP connection to Mainframe Connect.
