Deleting Archive from Target

MikeyH

Hi All,

Sorry if this has been asked before, I have searched and didn't find anything.

How do you delete archived (from TRND) data from the target device? Can it be deleted when you load a new configuration?

Cheers

Mike

Hi Mike,

thanks for your question.
There is only one way how to delete the archived data - just delete the files/folders on the target device.
Following line will delete all the archived data:

sudo rm -rf /rex/arc/

Hope it helps.

Regards,
Tomas

Perfect, thank you Tomas. Can the command be run via a block?

Sure Have a look at function block called EPC - https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/EPC.html#x265-26400015

For details on how to use the EPC function block, head to example on MP3 Playback: https://www.rexygen.com/example-projects/0304_External_Programs/0304-02_MP3_Playback/0304-02_MP3_Playback.html

Thank you Tomas,

If I use the block to run the command to delete the archive. Can this be done while the process is running, will REX create a new file straight away? Or should I reboot once the file is deleted?

Cheers

Update! I have tried this and it seems you can run the command while the execution is running. But for a new archive file to be created you need to reboot.

Hi Mike,

thanks for update on this. The reboot isn't necessary. The file should be created also when:

new write of archived items is performed to the disk with specified period
swapping executives
when AFLUSH is triggered - see: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/AFLUSH.html

Let me know if it work for you.

Cheers,

Hi Tomas,

Thank you for the reply

Rebooting, swapping executive and AFLUSH work fine, new data being written to the disk in time period does not work though.

Cheers
