Log shipping and shrinkfile are compatible. Shrinking the log file does not break log shipping, unless you specify to truncate the log. Truncating the log DOES break log shipping as you are breaking the tlog chain. A regular shrink file is fine though.
How often are you running tlog backups through the log shipping plan?
If I understood you correctly, that is not what shrinking does. It releases free space within the log file (and so the file size will change), but it will not logically change anything in the active portion of the log. How much free space do you have? Run this to see
Thank you everyone. I will leave the file for now. Just had some time and was thinking about the log file size. A while ago it had grown to half the total drive space (100G) and I had to shrink the file and restart log shipping. This is not the only database log file on the drive.
But if I can remember this thread I will not try to do something not nessasary.
