A backup/recovery solution for WebSphere MQ for z/OS using a volu me flash copy

[Middleware Group Mailbox]

Hello,   I am working on a backup/recovery solution for WebSphere MQ for z/OS. At our shop we are already doing a volume (DASD) flash copy backup. The DB2 system programmers use the SUSPEND, RESUME commands before and after the flash copy to allow in-flight transactions to commit and to block any new transaction to access DB2. Are there similar commands for MQ, which will suspend any I/O operation to the PAGESETS or to MQ as a whole until the flash copy is ended?   I know there is the ARCHIVE LOG command, but this command seems to deal only the MQ active log data sets.   Thanks,...
