SAP Note 26420 - brbackup runtimes longer after OS upgrade

Symptom:

brbackup runtimes are longer after the OS upgrade from DEC UNIX 2.x to 3.2x.

Cause and prerequisites

This is caused by a new cpio.

Solution
The cpio installed in the system under OSF 3.2 has a different saving structure. If you look at the cpio in /usr/bin or /sbin, you can see that the cpio, tar and pax have the same inode. This is a single program which internally processes the 3 different tools, distributed in 2 directories (once with libraries and once without).
The "old" cpio which is installed on the system or which must be installed can help here.
To do this, you have to install the following subset (all the following commands are performed as the user root). # setld -i |grep OBSOLETE
OSFOBSOLETE3n0 installed Obsolete Commands and Utilities (System
If this subset is installed , you can find the "old" cpio in /usr/opt/sterling/usr/bin or /usr/opt/sterling/sbin.
The "old" tar can also be found here.
Now move the "new" cpio and tar for security. # mv /usr/bin/tar /usr/bin/tar.newer
# mv /usr/bin/cpio /usr/bin/cpio.newer
(pax can stay where it is).
Now copy the "old" cpio and tar into here # cd /usr/opt/sterling/usr/bin
# cp tar cpio /usr/bin
# cd /usr/opt/sterling/sbin
# cp tar cpio /sbin
Afterwards, the brbackup should run with the same time as before.
PS:
If the subset specified above is not installed, you can install it at any time. For this, you need the DEC UNIX CD for your current operating system (here 3.2n).
Mount the CD as follows. # mount -dr /dev/rz4c /mountpoint_cd (rz4c stands for the CD device)
These subsets can be found in the directory /mountpoint_cd/ALPHA/BASE.
Install the required subset as follows. # setld -l /mountpoint_cd/ALPHA/BASE OSFOBSOLETE3n0
