Error description
Problem between a JMS client and a queue manager, when using ISDN/DSL. During a MQGET the client gets: MQJMS2002: failed to get message from MQ queue Reason code RC 2009, MQRC_CONNECTION_BROKEN. . Conclusion: . When an InterruptedIOException is caught and handled, MQ assumes that a socket timeout has occurred and will initiate a retry and read the data again. In cases where part of the data has already been read the data received is ignored and will be overwritten. .
Local fix
Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of the WebSphere MQ Version 6.0.2 classes for Java and classes for Java Message Service (JMS). Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java **************************************************************** PROBLEM SUMMARY: The readFully() method, used internally by the WebSphere MQ classes for Java and classes for JMS to read data from a socket, did not have the ability to record the number of bytes which had been transferred prior to an InterruptedIOException being thrown. The InterruptedIOException itself has a field called bytesTransferred but this does not work either due to a Java bug.
Problem conclusion
The readFully() call has been replaced with an iterative call to readByte() so that the number of bytes that have been read can be recorded, and any subsequent attempts to read bytes following a connection error can resume from the correct position. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v6.0 Platform Fix Pack 6.0.2.9 -------- -------------------- Windows U200313 AIX U828012 HP-UX (PA-RISC) U827381 HP-UX (Itanium) U827383 Solaris (SPARC) U827693 Solaris (x86-64) U828055 iSeries tbc_p600_0_2_9 Linux (x86) U827380 Linux (x86-64) U827694 Linux (zSeries) U827590 Linux (Power) U827382 Linux (s390x) U827695 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available, information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
