Using the following parameters, you can limit the maximum use of the process-specific memory. This in turn limits the maximum use of temporary memory by an R/3 application server.

Consider the following parameters:

Parameters for Controlling the Use of Temporary Memory:

Parameter

Limitation:

ztta/roll_area

Roll area per internal mode

ztta/roll_extension

Extended memory limit per user context

rdisp/PG_SHM

Paging memory per application server

rdisp/PG_MAXFS

Paging memory per application server

abap/heap_area_dia

Heap limit for a dialog work process

abap/heap_area_nondia

Heap limit for a non-dialog work process

abap/heap_area_total

Heap limit for the entire R/3 application server

For more information about the function parameters, see Allocating Memory for User Contexts.

Temporary memory almost completely covers the memory requirements of R/3. The main consumers are:

  • Internal buffers with a fixed share (PXA, table buffer, paging buffer)
  • R/3 memory management (roll memory, Extended Memory, private memory) with a variable share depending on the number of users logged on and the application type (direct memory requirements)

In the following cases, it could be necessary to use a temporary license to bridge the time until the SAP license has arrived by fax:

  • If the hardware configuration of the host on which the message server is running changes, the customer key of the host can also change.
  • If the message server is moved to another host.
  • If the license has expired. The expiry date can be extended by 3 weeks with the temporary license.

Procedure

  1. Log on to the host on which the central SAP instance is running as user
    2.  adm (UNIX and NT) or OFR (AS/400) at operating system level.
  2. Enter saplicense -temp (AS/400: saplicense '-temp').

Enter the SAP System ID when it is requested.

The following message shows that the program has terminated successfully:

saplicense: Temporary license successfully installed

Rejection of a Temporary License

SAPLICENSE rejects installation of a temporary license in certain cases:

  • A temporary license can only be installed if a valid license existed and has been used recently (within the last 3 weeks).

The following message tells you that a temporary license cannot be granted because the date of the last successful license check was more than 3 weeks ago:

saplicense: Temporary license NOT installed, *** Old license older than 3 weeks
  • If the R/3 System is set up from a copy of an existing R/3 System, it is not possible to install a temporary license for the first time.

Apply for a license before you want to work with an R/3 System that has been copied.
