  • 1.  Creating MQ Queue Managers on NFS file system on Windows

    Posted Thu October 04, 2018 04:16 AM
    Hi

    We have an NFS share attached to Windows 2012 R2 server. We are trying to create a multi-instance queue manager by running the following command:
    C:\Users\svc_ibm_mq>crtmqm -sa -u SYSTEM.DEAD.LETTER.QUEUE -md "\\10.117.120.205\export\ssvsmqqashc1and2_d\wmq\data" -ld "\\10.117.120.205\export\ssvsmqqashc1and2_d\wmq\logs" QMGR111
    AMQ8101S: IBM MQ error (893) has occurred.

    see below error log details

    Hi Sandile,

    unfortunately, NFS v4 is not supported for queue managers running on Windows.

    Although the information is tricky to find, the only supported file system for running MIQM on a network filesystem on Windows is CIFS.

    On page:  https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_9.0.0/com.ibm.mq.con.doc/q018150_.html 
    the statement is item 6:
    The shared log and data directories cannot be stored on a FAT, or an NFSv3 file system. For multi-instance queue managers on Windows, the networked storage must be accessed by the Common Internet File System (CIFS) protocol used by Windows networks.

    Regards.

    Neil

    Hi,

    I don't know if you can mount to NFSv3 on a Windows server, but I don't think so like Neil comments, default Windows is SMBv3.

    CIFS is a dialect of SMBv3, you can ask your Windows system admin or  CIFS is part of your file system.
    Microsoft SMB Protocol and CIFS Protocol Overview
    Microsoft remove preview
    Microsoft SMB Protocol and CIFS Protocol Overview
    The Server Message Block (SMB) Protocol is a network file sharing protocol, and as implemented in Microsoft Windows is known as Microsoft SMB Protocol. The set of message packets that defines a particular version of the protocol is called a dialect. The Common Internet File System (CIFS) Protocol is a dialect of SMB.
    View this on Microsoft >
    .

    Advice:
    Its very important to have the same Windows version's including fixpacks on both MQ machines AND you're fileserver. We run MQ v8 Multi instance for serveral years on Windows 2012 R2 on VMWare and we had lot of problems with it. If you use VMWare don't use Vmotion, its killing the MQ proces. Create a huge SWAP drive, we have it at 50 GB with 8GB of RAM per machine. Create the SWAP on a seperate share.
    If I might advice you switch to Linux OS if that is possible !
    Kind Regards.

    When using the crtmqm command you must supply the -sax rather than -sa parameter to create a multi-instance queue manager.

    We were able to get a multi-instance QMGR working on Win2012 with NFSv4 a few years ago, so I might be a bit rusty, but make sure your mqm user has full access to the mounted drives, we had to run a command similar to
    icacls G: /grant mqm:F
    for each of the file systems.
