Non so se in relazione a queste restrizioni succede che il db2, in fase di connessione ad uno o più db risponda:\\
Shared memory segments cannot be allocated. SQLSTATE=57019\\
\\
Nel log del db2 dice:\\
MESSAGE : ZRC=0x850F0005=-2062614523=SQLO_NOSEG
"No Storage Available for allocation"
DIA8305C Memory allocation failure occurred.
DATA #1 : <preformatted>
Unable to attach 10 segments totalling 2521759744 bytes starting at address
0x00000000. One possible cause may be an improper setting for the
shmmax Linux kernel tuneable.
\\ \\
Leggendo su internet ho provato a cambiare la shmmax (per ubuntu)
%%prettyif
{{{
#così vedi la shmmax allocata dal sistema operativo
vi /proc/sys/kernel/shmmax
#provare a modificare tale impostazione in questo modo
vi /etc/sysctl.conf
#e aggiungere in fondo
kernel.shmmax = 4153352000
#Per applicare la modifica senza fare il reboot della macchina
sysctl -p /etc/sysctl.conf
#riverificare se è cambiato il valore shmmax rieseguendo il primo comando
}}}
NOTA:\\
Il valore da impostare per shmmax è da stabilire...metà della ram disponibile???\\
Dopo tale modifica non so per quanto il tutto possa funzionare\\
