ITOB - Modify RBUF_MAX

[Former Member]

Hi,

I have a note and I have to do this modifications. But i dont know where I can modify the RBUF_MAX...in the database parametrization?

Thanks

<i>You can use a modification to further increase the values as appropriate:

• Using Transaction SE11, you must go into type group ITOB in change mode.

• Now change the value of RBUF_MAX from 7500 to a higher value, such as 20000.

• Now change the value of RBUF_MAX_U from 5000 to a higher value, such as 20000.</i>

Hi Mpm,

You go to SE11 transaction.

Under the radio buttons like Database tables, ... do you see an option called "Type Groups".

a, If you do choose, this option and enter ITOB, press change.

b, if you cant see the type group option, goto utilities menu in SE11. Press Other Dictionary objects in the menu.

Now do what is mentioned in step a.

You will now see the type groups definitions.

Search for RBUF_MAX definition, and replace 7500 with 20000.

Similarly repeat for RBUF_MAX_U.

I guess the problem for you would have been the option b (not able to see type groups in the radio buttons).

This surely shd solve your problem, if it does, pls reward points.

Hi,

I think your note is a manual note.

Get the access for the type group ITOB from Basis guy and change the same according and create a request for the same.

The ITOB is RBUF_MAX with value

• size of read buffer which leads to unconditional refresh of buffer

RBUF_MAX TYPE I VALUE 7500,

• size of read buffer which leads to refresh of buffer in case of

• unsuccesful read request from read buffer

RBUF_MAX_U TYPE I VALUE 5000,

Thanks
