Closed as program error.
Error description
When using the mqrc command to convert an MQ error file into JSON format, corrupt message text is output. This occurs for languages other than English. For example, running the command: cat AMQERR01.LOG | mqrc -i text -o json -d ja_JP - results in output similar to the following: { "ibm_messageId" : "AMQ8004I", "ibm_arithInsert1" : 0, "ibm_arithInsert2" : 0, "ibm_commentInsert3" : "QM1", "ibm_datetime" : "2019-01-22T19:41:52.415Z", "ibm_serverName" : "MY_QMGR", "type" : "mq_log", "host" : "localhost.localdomain", "loglevel" : "INFO", "module" : "amqzxma0.c:1947", "ibm_sequence" : "1551828271_599749890", "ibm_processId" : "16961", "ibm_threadId" : "1¼¸£¼ 'MY_QMGR' µº¾ "}, "ibm_userName" : "user1", "ibm_installationName" : "Installation1", "message" : "AMQ8004I: IBM MQ ¥¼» }
Local fix
Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of the mqrc command when using the JSON output format in languages other than English. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: JSON data must be encoded in UTF-8 which is not always how the IBM MQ message catalogues for different languages are encoded. The mqrc command therefore attempted to convert character data from the retrieved from message catalogues and written to the JSON output, such as for the "message" field. However, if the system locale was already running in UTF-8 and inherited by the mqrc command, then the message catalogue data would have already been converted into UTF-8 before being passed to the mqrc JSON output processing. As a result, an incorrect attempt at an additional conversion was made. This additional conversion assumed that each character in the data to convert was encoded using a single-byte, which resulted in a corruption of the already valid UTF-8 bytes.
Problem conclusion
The mqrc command has been updated to ensure that message catalogue data is already converted into UTF-8 before being passed to the JSON output processing. As such, no further conversion is required or attempted. This APAR applies to all platforms except IBM i. Please see APAR SE71857 for the corresponding change on IBM i. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD 9.1.5 v9.1 LTS 9.1.0.4 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 ---------------------------------------------------------------
