Hi
mqsiver: 6.0.2.8
aix: 6.1.0.0
Does someone knows how to rotate logs of TraceNodes without a restart of the execution group (EG) under AIX?
The problem is that the open file handle still hangs on the inode after renaming the file. Only by restarting the EG the handle is closed and a new file will be created.
copy and "cat /dev/null" to the original somtimes seems not to be the best option.
Thank you.
BR,
H.M. |

Are you using the Trace nodes to routinely log flow activity? That's not a good idea, for reasons you seem to have discovered. Trace nodes are intended as a debugging tool.

I know. But I can not influence this situation. |

There are some standard Unix mechanisms for dealing with files that need to be managed when the outputting program does not release the file handle - i.e. Unix shell scripting.
You should be planning or in the middle of a migration to Broker v7 or at least v6.1, as v6.0 goes out of support early next year. |

Thank you.
The migration is still planed.

Not very helpfull. I read about a logrotate package but the app that holds the filehandle has to support the SIG to release it.
But...you are rigtht. If the EG not support this i have to search the solution only with OS "tools". |
