Hello,

I need to move MQHRF2 messages from one QMGR to another, but when I try to load messages from the file, I get

MQPUT(Q1) failed RC(2334) RFH Error

Is there any way to perform this task?

Thank you.

Does it fail if you don't run it through dos2unix first?

Edit: The -P option of dmpmqmsg may be of interest to you.

Yes, I run dos2unix first, because otherwise it just fails on the structure of the file.

-P as I see for CCSID conversion ... It's 1208 on both qmgrs.

You have Windows set to 1208 (UTF-8 equivalent), rather than its native code page?

Have you dumped out the messages in ASCII format, using the -dA switch of dmpmqmsg, to see whether the message content is correct?

Last gasp suggestion is to use dmpmqmsg in client mode (-c) from the Linux box and pull the messages directly from the Windows box.

Also, you state that "...it just fails on the structure of the file." - can you post the actual failure message from dmpmqmsg?

Dumped it with -dt, I didn't see anything special

I will look into -c, thanks.

It fails on the structure of the file, if I don't run "dos2unix", makes sense.

What was the reasoning behind this please?

The Knowledge Centre states for the -dt switch: This format is not code page safe. Loading a file written in this format, while running in a new code page does not guarantee to produce the same message., hence why I suggested using the -dA switch to check.

Perhaps it's failing because you are dumping it non-thread-safe?

Would you please post the exact command you are using, and the exact error message you are seeing in regard to the file structure, thank you.

"exact" means complete error message with message-id (AMQnnnn), message text, environment variables you set, command(s) you issued.

The 1208 code page is what customer has for years in the older environment ... It's just a given fact

Command on MQ8 Windows used to extract:

dmpmqmsg -iQL.APP1 -mQM.APP -fdump.msg

Command used on MQ9 Linux to load:

MQ_DATA_PATH="/var/mqm"
MQ_ENV_MODE="64"
MQ_INSTALLATION_NAME="Installation1"
MQ_INSTALLATION_PATH="/opt/mqm"
MQ_JAVA_DATA_PATH="/var/mqm"
MQ_JAVA_INSTALL_PATH="/opt/mqm/java"
MQ_JAVA_LIB_PATH="/opt/mqm/java/lib64"
MQ_JRE_PATH="/opt/mqm/java/jre64/jre"

dos2unix dump.msg
dmpmqmsg -oAPP.Q4 -mJMSQM -fdump.msg

5724-H72 (C) Copyright IBM Corp. 1994, 2022.
IBM MQ Queue Load/Unload Utility
MQPUT(APP.Q4) failed RC(2334) RFH Error
Read - Files: 1 Messages:1 Bytes:909
Written - Files: 0 Messages:0 Bytes:0


File dump.msg has 3 message.


I also tried to extract the messages to file directly from Linux server, using -c, so I won't have to run "dos2unix". But it throws the same error about RFH, when loading.

Queues that don't have messages in MQRFH2 format, are extracted and loaded correctly.

What does the content of the file look like before running dos2unix, and what does the content of the file look like after running dos2unix?

Don't use dos2unix, ftp the file as text to Unix. Load there with dmpmqmsg.
