Re: ontape and large delays reaching first 10% complete

John: We have experienced this while we were using 7.x version due to the Informix bug. Informix had a following fix for that, we continued same setting on 9.3 UC3 also (just in case) Add "CCFLAGS 0x400000 " in the $ONCONFIG file and recycle informix server and try backup to see whether that helps.

I still see that behavior on 9.x systems. From last night: Informix Dynamic Server Version 9.30.UC2 -- On-Line -- Up 11 days 09:22:27 -- 169292 Kbytes Please mount tape 1 on /var/opt/informix/inst10/backups/level0.pipe and press Return to continue ... 10 percent done. 20 percent done. 30 percent done. 40 percent done. 50 percent done. 60 percent done. 70 percent done. 100 percent done. Is there any way to speed the scan up?

I would be very cautious about implementing this particular setting without consulting tech support.
