Hi
We had the following error in our FDC logs (hrcE_MQLO_SHAR) but cannot find anything about on the web as to its meaning.
Can any one help, or advise me where to look. i have copied the FDC header below. I know it has something to do with logging, but not sure what. The Qmanager that generated this is using circular logging.
Thank you in Advance

Under what circumstances? Starting the queue manager? Closing the queue manager? Queue manager under heavy load? Coffee machine dispensing tea instead of coffee?
A brief squint indicates a file system error of some kind. Make sure Windoze is patched to the latest, and upgrade to WMQv6.0.2.5 if you're using MCSC.

Hi
Thanks for that
The QManager was processing a single file as per normal, which contains over 100K rows. This kind of processing has been going on successfully for quite a long time, and its the first time weve seen an error like this.
may i ask how you came to thinking its a filesystem error? |

I asked Mr Google. There was a similar problem in an earlier version which is apparently fixed in the v6.0.2.3 that you're using, and another similar issue using MCSC which is fixed in v6.0.2.5 hence my comment.
All the issues for that FDC seem to revolve round the file system the log is on throwing (correctly or incorrectly) errors.
I'm confused by your comment that the queue manager "was processing a single file with 100,000 rows". Queue managers process messages not files, and messages don't have rows. It does indicate that you have quite a large UOW going, so this adds weight to the log file running out of space / thinking it's running out of space / thinking it's corrupt / thinking it's a tree / deciding it's Windoze so will spontaniously break / running out of file index / etc / etc.
Try it with a smaller file. If that works, increase until it breaks and this will give a clue.
If you've no time for that, raise a PMR.

Sorry Vitor for the confusion what i meant was
a single file picked up by our FTMM (File To Multi Message) adapter which contains 100K rows, each of which is processed as a single message.
Thank you again for your help. I will ask out server administrators if they noticed any errors on the server, as i couldnt see anything in the event logs. also one more thing what is MCSC? |

It's MSCS when you're not looking/thinking carefully about what you're typing!
