Global swap space is nearly full

[Dennis Handly]

>maybe oracle not correctly configured?

It seems you have too much SGA space configured.

You need to get Oracle to release those shared memory segments.

Thank you Dennis Handly.

It seems that, as is.

Thank you very much/

I shutdown all oracle db and restart the hp-ux , but

> shmmax 137256417362

I would say that's way too much, more than your memory.

[0rb1t0]

i calculate this by formula:

127,83*1024*1024*1024=137256417362

sorry I dont understand, right value

>I calculate this by formula:

I would cut it in half, since you can't really get a segment that big, without swapping.
