Yes.
On Z/OS you can also index the queue by MSGID for a performance gain. |

But remember, the msg id is a bit stream and not in human readable format.

Hi,
I have an ILE RPG PROGRAM that reads the Message (Basicaaly the MEssage ID ) and Store it in the Data base, Another ILE program will pick up the data (Message ID) and look for the MEssahe in the Queue for the Specific Message Id.
Wat r the steps needed to be done.
In Windows When i am browsing Message using MQExplorer the following is shown as the MEssage ID
AMQ QA.TEST.D{¶LD
414D512051412E534B414E4449412E447BB64C4420000F01
which one is the MessageID |

Hi,
both, the first one is the MessageID translated to readable ASCII characters (some at least).
The second one is the original hex string which is stored within the MQMD.

41 => A
4D => M

Hi fschofer

414D512051412E534B414E4449412E447BB64C4420000F01
Message id to store in the database and using this value can i retrive the MEssage from the Queue with the Same Message id

No. Before you retrieve the message you need to transform this String into a byte array with the values as specified by the hex string:
1st byte value 0x41
.....
3rd last byte value 0x00 (c string terminator)...
2nd last byte value 0x0F
last byte value 0x01
Enjoy

nik_iway, I have a similar requirement. Are you getting the MessageId in HexString using the method suggested by Leigh Kendall? How are you converting the HexString back to Byte array while retrieving the response?
Thank you,
Manesh |
