hardlimit and swap space - pre requiste for oracle

Hi

 

I am installing oracle 11 g in hp ux 11 i v3.

 

While Installing oracle,it got failed due to pre-requiste was not met.

 

 

i am getting failure at swap space and hardlimit.

 

1.How can i change the hard limit  ?

2.How can I change the swap space size.

Re: hardlimit and swap space - pre requiste for oracle

I understand that I can't extend the primary swap until I re ignite the os. Is it possible to create secondary swap in vgoo in the same disk ??

Which?  maxdsize_64bit?  You can use kctune(1m) to do that.

You don't need more swapspace, you need more memory.  Otherwise you'll be very slow.

How do you say that I need more memory. Can you explain ?

If Oracle says you need more swap, that's too slow if it wants to use it for the SGA.

Why don't you increase maxdsize_64bit and then see what Oracle says about how much swap you need.

You already have about 15 GB.
