This readme file contains a list of known issues, workarounds, and updates for the IBM® IMS™ Enterprise Suite Version 2.2 Connect API for Java™, for both z/OS® and distributed platforms.
This document contains the latest information about known issues, workarounds, changed product behavior, and updates for IBM IMS Enterprise Suite Version 2.2 Connect API for Java™. This document supplements the IBM Information management Software for z/OS Solutions Information Center, which is located at http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp.
Note: The Connect API for Java ZIP file for Windows™ is available in two versions:
- A ZIP file that includes only the API library (JAR file), the sample applications library, and the readme and legal notices text files. This ZIP file is named IMSES_ConnectAPIJava_V2.2.0.x.zip. Download this version if you already have Java 6 or later.
- An IBM Installation Manager repository ZIP file. IBM Installation Manager 1.5.3 or later is required. The Installation Manager repository contains all of the previously listed files as well as the installer for the IBM SDK Java Technology Edition, Version 6. This ZIP file is named IMSES_ConnectAPIJava_V2.2.0.x_WithJVM.zip. Download this version if you need Java.
See Installing the Connect API for Java on Windows ( http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/topic/com.ibm.ims.iconapij22.doc/ies2_install_dist.htm) in the IBM Information Management for z/OS Solutions Information Center for more information.

Updates and service
March, 2013: Version 184.108.40.206 is available for the Windows platform. This fix contains additional logging functions for client applications. See the Documentation section below for more information. To obtain the fix, visit the IMS Enterprise Suite download website:
February, 2013: Version 220.127.116.11 is available for the z/OS and Windows platforms. PTF UK91746 for APAR PM81423 contains this service. This fix contains additional logging functions for client applications and updates the log file to display synchronous callout correlation tokens in hexadecimal instead of EBCDIC encoding for readability. See the Documentation section below for more information about the new logging controls. Get more information about the APAR and obtain the fix:
For Windows, visit the IMS Enterprise Suite download website to obtain the fix: https://www14.software.ibm.com/webapp/iwm/web/preLogin.do?source=swg-imsentersuite
February, 2013: Version 18.104.22.168 is available for the z/OS platform. PTF UK91004 for APAR PM77947 contains this service. Get more information about the APAR and obtain the fix:
January, 2013: Version 22.214.171.124 is available for the Windows platform. This service corrects a problem with the value of the retrieved MfsModName property in certain scenarios. This service is a complete replacement for the API library.
November, 2012: A fix for APAR PM75838 is now available for the z/OS platform. This service includes fixes for several minor issues. The base 2.2.0 version for Windows includes these fixes.

Problem: When the Connect API for Java sends a Send-Only-With-Ack error response (with NAK reason code) to an IMS synchronous callout request, IMS Connect returns a NAK response even if the error response and reason code were successfully received by OTMA. However, the IMS application that initiated the synchronous callout request receives the NAK reason code from the API client application normally.
Workaround: If the NAK response from IMS Connect has return code 16 and an OTMA sense code equal to the NAK reason code sent by the client, you can treat the NAK response as if it were an ACK response.
Problem: The API does not correctly process 2-dimensional byte arrays used as the source data for a response message to an IMS synchronous callout request. If multiple rows are specified, the API can enter a loop condition.
Workaround: Use a 1-dimensional byte array or specify all of the response data in the first row of a 2-dimensional byte array (A).
Problem: The Connect API for Java client application receives an HWS0001E error message with a null pointer exception while executing the type-2 command QUERY TRAN NAME or UPDATE TRAN NAME, or when retrieving information from a Type2CmdResponse object, if the entered QUERY was not in the right format.
Workaround: Use only well-formed type-2 command queries.
Fix: Included in PTF UK83045.
Problem: The Connect API for Java client application receives an HWS0018E error message after submitting an invalid IMSPlex name in a QUERY IMSPLEX type-2 command.
Workaround: If your application receives an HWS0018E message, check that the IMSPlex name is correct.
Fix: Included in PTF UK83405.
Problem: The Connect API for Java client application receives a HWS0018E error message when a type-2 command response contains an RSM.
Workaround: No workaround is available for this issue.
Fix: Included in PTF UK83405.
New API logging functions for version 126.96.36.199: These methods are available in the ApiLoggingConfiguration class. Set these logging configuration properties before calling configureApiLogging. You can use these controls in combination with the controls added in version 188.8.131.52.
Sets the maximum number of bytes that can be written to an API log file through the Connect API logging file handler.
public void setLoggerFileLimit( int aLimitValue)
Gets the maximum number of bytes that can be written to an API logging file.
public int getLoggerFileLimit()
Sets the number of sequential log files files that the API log file handler will create before overwriting the first file.
public void setLoggerFileCount( int aCountValue)
Gets the API logging file handler's count for the number of files to use of the Connect API logging file handler when one file has reached its Limit.
public int getLoggerFileCount()
New API logging functions for version 184.108.40.206: These methods are available in the ApiLoggingConfiguration class. Set these logging configuration properties before calling configureApiLogging.
Sets the API logger to either append to the existing log file (true) or overwrite it (false).
public void setLoggerToAppendMode( boolean aBooleanAppendValue)
Gets the current logger append mode.
public boolean isLoggerAppendModeEnabled()
Gets an API log file handler.
public Handler getLoggerFileHandler()
Restriction: IMS Connect support for Unicode character encoding cannot be enabled with the Connect API for Java. You can manually enable Unicode for input messages by setting the IRM_F1 X'20' flag bit on behalf of the input message with the IMS Connect User Message Exit. To use Unicode trancodes as well, you must include the trancode at the start of the input message data and set the IRM_F1 X'10' flag bit with the exit. In either case, indicate UTF-8 encoding with the IRM_ES X'01' flag bit.
