Segmentation fault (Core dumped)
I'm trying to import my yesterday's production DB on another machine for some testing purpose. I created a clone of my production DB, but with a block size of 4KB unlike as production 8KB. My OS is Linux 7.2 and oracle 126.96.36.199.0 . Import process is starting and at after creating 4 tables, its kicking out saying
"Segmentation fault (core dumped)". I set all the Shared memory parameters and all. here are my shared memory parameter values..
[root@cmsprod3 kernel]# cat sem
250 32000 32 128
Please help me in solving this problem.
Thanks in advance.
Imp w/ analyze=n
That's a bug that was supposed to be fixed in 9.0.1
You mean to say, import with analyze=n??
or, you could re-export with statistics=n
ken, Getting the same error again even after using analyze=N option.

Type "ulimit -a" and post the results.
[oracle@cmsprod3 oracle]$ ulimit -a
core file size (blocks) 1000000
data seg size (kbytes) unlimited
file size (blocks) unlimited
max locked memory (kbytes) unlimited
max memory size (kbytes) unlimited
open files 1024
pipe size (512 bytes) 8
stack size (kbytes) 8192

max user processes 81919

That looks good.
Are the NLS_LANG's the same?
Is this something you do routinely and it just failed today?
I think the max user processes are very less, bcoz the same value for this in my prod DB is ..
max user processes 196608
Will this effect? if yes, how can i change this value to the required one?
No, its of some thing like one time job, but when i imported the same DB on some other 2 more machines, with same OS , every thing same, it went fine, but not on this Box. Can you please throw some light on this. B'coz, i need to prepare this today and make it ready for my developers.
Many Thanks in advance
