About prepare phase syncronization

Dear Erman,

We are on R12.2.5 with delta 7.Could you please let us know how prepare phase with sync_mode=delta is different from prepare phase without sync_mode=delta

Thank you

It is the fastest way for synchronizing..

Here is the official definition of that;

synchronization method uses your choice of third-party utility to synchronize the file systems by copying files as applicable from the source directory to the destination directory, optionally ignoring any files and directories you may decide to specify in an exclusion file. Specify the parameter sync_mode=delta to use this synchronization method.

Thanks for the update erman.

Pls correct me if my understanding is wrong

prepare phase with sync_mode=delta uses rsync
Prepare phase without sync_mode does not use rsync

Thank you

As I said, "sync_mode=delta" uses "your choice of third-party utility" to synchronize the file systems by copying files as applicable from the source directory to the destination directory.
So it can be rsync or any other tool.
you specify it in delta_sync_drv.txt
In delta_sync_drv.txt you will find examples as well. These examples are based on the rsync style synchronization, but as I said; you can use "your choice of third-party utility".
Rsync is not a must.
