Hi,
For introducing a delay while processing a message in a message flow I had used the timer node in version 6 but in Broker 7, there is a Sleep ESQL function. Is this the recommended way to introduce a delay in a message flow now as I could not find an equivalent Broker java API for it (not Thread.sleep() but something like getMessageFlow().sleep()) |

I thought you'd come across
| Code: |
long mysleep = 1000l; //in ms
Thread.currentThread().sleep(mysleep); |
Sleep has been available in Java forever... however it needs a catch block and can be interrupted...

yes i do agree, but some time i feel like the thread [Message flow] is taking time to get paused. and i guess that is desired too.
internally i dont know how the ESQL SLEEP works, will it pause it the instance when we call it, or it will take time to pause [say for complete the transaction and pause it]

Sorry for the delay in replying, I missed this append before. The ESQL SLEEP will sleep immediately it is called for the specified duration. It is automatically interrupted if the flow is reconfigured...

| Does it terminate if the broker or EG is stopped? |

Hi,
I am trying to use the sleep function in WMB 7.0 'SLEEP(1000);'. It is showing error. Do we need to install any adapter to get this function availabale in WMB 7.0?.
Thanks,
Veera |

According to the documentation,
Sleep is a FUNCTION that returns a BOOLEAN.
Are you calling it as a Function or a Procedure?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

I am calling it as a esql function in compute node. I tried to search it in help WMB 7.0. I did not find that. Finally i got this infocenter link from this thread. thats why I am suspecting that this may require a adaptor for using sleep function. Please help me out to make use of sleep().
Thanks,
Veera |

DECLARE bRes BOOLEAN;
SET bRes = SLEEP(1000);

Hmmm. That seems to be fine for me, at least as far as compiling the ESQL goes.
What have you tried? What are your exact errors?

What version of the toolkit do you have?
Can you post the exact error that you are seeing? |

Hi,
I have used the same code. But it is showing error on 'SET bRes = SLEEP(1000);' statement.
I am using WMB 7.0 version. |

Well SLEEP was added in 7.0.0.1 so you need to upgrade to use it...
Kind regards,
