Hi Mao,

For parameter, em/reserve_mapping_window it is be defaul on with kernel release > 6.20. Refer to SAP Note 373326 for details.

For parameters,

rdisp/PG_SHM = 8192

rdisp/PG_MAXFS = 65536

rdisp/ROLL_SHM = 16384

Its not mandatory to delete these parameters in ZAMM. If you delete these parameters they will take the system default values at startup.

Hence you may leave the setting as it is.

Hope it helps.

Hi Mao,

Point 6 (a,b) of the note 88416 recommends setting PHYS_MEMSIZE in case of CI+ DB on same host.

Point 6(c) recommends deleting PHYS_MEMSIZE since it talks about application server with one instance.

In your case CI is acting as a pure application server and hence PHYS_MEMSIZE could be deleted if this has only one dialog instance.

Hi Rupali,

Great!! now i understand what you mean.

just calify again. beside i removed the memory parameter PHYS_MEMSIZE, also do i need remove the following parameter?

em/reserve_mapping_window = on

rdisp/PG_SHM = 8192

rdisp/PG_MAXFS = 65536

rdisp/ROLL_SHM = 16384

our system setting in profile is as follow i think.

#----

---

PHYS_MEMSIZE = 3072

#----

em/reserve_mapping_window = on

rdisp/PG_SHM = 8192

rdisp/PG_MAXFS = 65536

rdisp/ROLL_SHM = 16384

thanks a lot.

Hi Mao,

Since its a 32 Bit system, is 3GB option activated in your system. Refer to SAP Note 110172.

Do you have DB on the CI server? What i understand from the above answer that DB is standalone. If yes, then you may delete the parameter PHYS_MEMSIZE, please refer to SAP Note 88416 for Zero Administration Memory Management settings.

Hi Rupali

yes, it's 32 Bit system and 3GB option activated aleady.

on CI server only is CI. DB is standalone. i don't think need to delete parameter PHYS_MEMSIZE, Please check carefully for SAP Note 88416 for Zero Administration Memory Management settings.

any one can help me modify the paramete which i have posted and then post here again? that would be much apperiated.

Hi Manoj,

see my answer below:

Is this a 32-bit windows system?

Mao: Yes.

How much physical memory u have?

Mao: physical memory = 4GB

What DB and how much memory allocated for that?

Mao: oracle 10.2.0.2. but the database server is separated with SAP application server.

see the memory allocation for db server.

shared_pool_size = 603979776

db_block_buffers = 120000

btw: I have implemented the zero memory management on sap server. but i still got some part

of users entered into PRIV mode.

Is this a 32-bit windows system? How much physical memory u have? What DB and how much memory allocated for that?

Hi,

Because he consumes too much memory.

You have to analyse what he is doing and if it is possible for him to consume less memory, for example, by reducing the quantity of data processed.

Some times it is not possible.

On our R/3 production system we had to restrict the maximum number of processes in private mode...
