Performance tuning ABAP Production system

$

0

Greetings, we have been advise to increase our SAP buffer area on all our servers by 20% (abap/buffersize) ensuring we have enough physical memory available on the server. I want to make sure I am doing this correctly. We are currently following the SAP Note 88416 - Zero adminstration memory management for ABAP servers. Since we are going to kernel 7.2, what suggestion do you have regarding the physcial memory and/or buffersize?

 

Please note the following:

SAP ECC EHP4

Window 2008 64 bit

Oracle 10.2.0.4

Kernel 7.2

 

System Parameters:

abap/buffersize = 400000 (increase 20% to 480,000)

abap/heap_area_dia = 2,000,000,000

abap/heap_area_nondia = 0

abap/heap_area_total = 17,176,723,456

abap/heaplimit  = 40,000,000

PHYS_MEMSIZE - 16,381

em/initial_size_MB: 16,381

em/max_size_MB 100000

 

ST04

Data buffer: 1,015,808

Logical read: 92,335,673,525

Quality: 96.7%

Physical read: 3,060,128,257

Size default pool (KB): 1,015,808

Physical write: 64,098,659

Buffer busy waits: 18,007,873

 

Shared pool:

Size (kb): 655,360

 

Buffer wait time: 54,244

 

We had a big performance issue ... we usually restart SAP to clear out the buffers but want to make tuning our permit solution...

 

Thank you in advance.

HI guys

 

after i finish benchrun, it takes about 2 hours.

 

i check st02 everything is good expect initial records.

 

it's hitratio  is 70%-85%, abap system is overloaded.

SAP ENQ process

Hi all

 

We are running occasionally into deadlocks in our ECC 6.0 System.

 

As per the SAP cursor cache we barely use all DIA Wps across all 4x instances that we consist of.

 

We already considered the number range buffering but due to legal requirements we cannot fully implement this.

 

We are running on an SAP EC 6.0 SPS11 System on HP-UX with 4 instances consisting of 3x APP Server and 1x DB (CI) based on Oracle 10.2 with around 5000 global users.

 

On our CI we do have 2x ENQ processes.

 

I just recently heard that having >1 ENQ (in our case 2x ENQ) could be a cause of deadlocks

 

The question I would have to the community is how many ENQ processes do you have in your SAP Systems?

 

I would be eager to hear of large SAP installations that consist of many ENQ WPs

 

I appreciate all feedback on this topic

Hi All,

            I am getting the dump TSV_TNEW_PAGE_ALLOC_FAILED in program SAPLCOM_PARTNER_OB in LCOM_PARTNER_OB in line 165.

 

Short text

    No more storage space available for extending an internal table.

 

What happened

 

You attempted to extend an internal table, but the required space was not available.

 

The error is occuring in line

 

  INSERT GS_CURRENT_PARTNERSET INTO TABLE GT_PARTNERSETS.

  CT_PARTNER[] = GS_CURRENT_PARTNERSET-PARTNER[]. "#EC ENHOK

 

ENDIF.

 

   The amount of storage space (in bytes) filled at termination time was:

 

   Roll area...................... 6221152

   Extended memory (EM)........... 3909511400

   Assigned memory (HEAP)......... 2000692032

   Short area..................... " "

   Paging area.................... 417792

   Maximum address space.......... 18446697117078316543

 

The dump is occuring in the standard program. Is there any note for this.

 

Kindly help.

Hello All,

 

One of customer background job running for long time more than 11 hours, but usually this jobs get completed within 4 hrs.

 

I have checked in WP trace file, it shows "WP has reached abap/heaplimit=40000000".

 

This is the Value I can see in RZ11. Now it is not possible to change the value.

 

Frequently facing this problem, please guide me to solve this issue.

SAP ENQ process

Hi all

 

We are running occasionally into deadlocks in our ECC 6.0 System.

 

As per the SAP cursor cache we barely use all DIA Wps across all 4x instances that we consist of.

 

We already considered the number range buffering but due to legal requirements we cannot fully implement this.

 

We are running on an SAP EC 6.0 SPS11 System on HP-UX with 4 instances consisting of 3x APP Server and 1x DB (CI) based on Oracle 10.2 with around 5000 global users.

 

On our CI we do have 2x ENQ processes.

 

I just recently heard that having >1 ENQ (in our case 2x ENQ) could be a cause of deadlocks

 

The question I would have to the community is how many ENQ processes do you have in your SAP Systems?

 

I would be eager to hear of large SAP installations that consist of many ENQ WPs

 

I appreciate all feedback on this topic

 

best regards
