SWAP SIZE Recomonded during instalation.

[Former Member]

Dear All

When installing Dialogue Instance, it shows an error as below :

Code:

Condition : Swap Size

Result Code : Condition not met

Severity : MEDIUM

Message : For the selected services at least 74228 MB swap space are recommended. Current value: 65536 MB. (Updated 2005-06-24)

Before it's size is of 40128MB, i extended it up to above value 65536MB.

But from that, i cant extended it as per the requirement mentioned above.

If i try to extend it shows as :

Code:

1. extendlv hd6 1G

0516-787 extendlv: Maximum allocation for logical volume hd6

is 512.

Please suggest me, How to proceed further, or is there any other way.

Waiting for your replies,

Thanks in advance,

Regards

Hi Vamsi,

1. extendlv hd6 1G

0516-787 extendlv: Maximum allocation for logical volume hd6

is 512.

try this, find your rootvg pp size

#lsvg rootvg | grep "PP SIZE"

VG STATE: active PP SIZE: 64 megabyte(s)

Need to calculate how many new PPs are needed in the hd6

size x 1024 /PP Size

1x1024/64 = 16

extraPPs+current=New

16+512=528

extend the LV

#chlv -x 528 hd6

Hello,

probably you can ignore this error. The requirement is very large, if the system would take this amount of SWAP the performance will go down probably extremely.

I agree with Christian, if this is just sapinst prerequisite warning then you can continue by 'cancel' option and ignore the swap space recommendation at the moment.

Later if you really need to change the swap (either less or more), value can be modified.

Thanks

Hi,

Ideally Swap size should be 3 Times that of physical RAM. If your physical RAM is on higher end you can continue to have SWAP around 20 GB ( Unix) or minimal 2 times of RAM.

For your setup you can press cancel button and go ahead and complete the installation.

So what did you do to resolve the problem and go ahead with the Installation ?

If you can share the solution with us.

Hello,

This is Unix error, you should contact your Unix team to resolve this one. They have to extend a limit for something like PP etc.

Thanks
