Memory parameters , server need to restart ?

[Former Member]

Hi,

We are loading Bussines partners into R/3 . But we are unable to load some of the bp's , it throws dump with below values need to set

following profile parameters:

o ztta/roll_area (1.000.000 - 15.000.000)

Classic roll area per user and internal mode

usual amount of roll area per user and internal mode

o ztta/roll_extension (10.000.000 - 500.000.000)

Amount of memory per user in extended memory (EM)

o abap/heap_area_total (100.000.000 - 1.500.000.000)

Amount of memory (malloc) for all users of an application

server. If several background processes are running on

one server, temporary bottlenecks may occur.

Of course, the amount of memory (in bytes) must also be

available on the machine (main memory or file system swap).

Caution:

The operating system must be set up so that there is also

enough memory for each process. Usually, the maximum address

space is too small.

Ask your hardware manufacturer or your competence center

about this.

In this case, consult your hardware vendor

abap/heap_area_dia: (10.000.000 - 1.000.000.000)

Restriction of memory allocated to the heap with malloc

for each dialog process.

Parameters for background processes:

abap/heap_area_nondia: (10.000.000 - 1.000.000.000)

Restriction of memory allocated to the heap with malloc

for each background process.

Other memory-relevant parameters are:

em/initial_size_MB: (35-1200)

Extended memory area from which all users of an

application server can satisfy their memory requirement.

my OS is HP-UX ,SAP 4.72 kernel 640 unicode , oracle 9.2

Now my concern is is i change the memory parametres , how to activate with out restarting the instance. As i know that if i change any parametres in instance profile neeed to restart.

Now i can not down my production server , i need to activate it with out restarting.

Any idea.

Thanks

Hi Lisa,

I have answered your same request under Forums » Application Server » NetWeaver AS, General (). If the instance is installed under HP-UX where the dump occurs rather than a Windows application server, then this forum 'SAP on Windows' is not the correct location to investigate further.

If the dumps do happen on a Windows instance, then the following questions would be helpful also to determine what advice is valid in regards to possible memory changes:

- Is it a 32-bit or 64-bit SAP Windows instance?

- Are all recommendations of note #88416 in place?

- What is the dump type and memory used at time of termination listed in ST22?

Regards, Mark

HI Lisa,

GO To RZ11 enter the parameter name which value you want to change. check wheather Dynamically Switchable is selected or not if it is selected then you can change the parameter value there you need not to start your server but wheever your server will restart the original value will be store.

Hope it helps

RZ10 will allow you to make the change permanent, so do both RZ11 and RZ10.
