Hello friends.
We face a problem on two SAP-Systems. While doing a Full-Backup with BRBACKUP the SAP-System hangs up and isnt accessible.
After the finish it goes on as if nothing happened. Trying to access a transaction could take a long time or even doesnt work.
Same problem on a ecc6.0 and a NW7.3. Statistics are actual.
Here are some informations:
Solaris 10 with Zones ( Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC )
Zone-Config of one system NW7.3 example:
capped-memory:
physical: 30G
ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
open files (-n) 8192
pipe size (512 bytes, -p) 10
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 29995
virtual memory (kbytes, -v) unlimited
swap -s
total: 28656272k bytes allocated + 0k reserved = 28656272k used, 34258288k available

Another thing is that the SSD32 counts up to 100% utilization while doing a backup on this system.

I hope you can help us. Thank you very much in advance.
