Al02 vs st04

hi to all gurus,
can anybody tell me the difference between the t-codes al02 and st04 although both are used for checking the performance of the database.

hello,
AL02 is used as SAP Alert Monitor. You can setup alerts to monitor your system.
But now a days we are not using AL02. We are using RZ20 to set up CCMS monitor alerts.
ST02 gives you Tune summary. There you can find out all details about Memory parameters & all buffers. It highlights swaps in your system. You can also switch to other transactions also like Database performance, OS06 etc.
So ST02 is really very helpful monitoring transaction. Generally used to monitor system swaps & other buffer parameters
Hope you can get idea..

SSAA - System Administration Assistant

Hello ,
Can any one give some information on T-Code SSAA. We want to do a quick monitoring of our process chains, i know that RSPCM will do he job but we also want to know the start time and the end time of each and every process chain, at the same time we dont want to waste or put more time on this alone.
Also if any one can explain about the T-Code RZ20 as well,
points assured for all relevant answers.
Thanks in advance for all your help.

Hello Lalitha,
SAP Processing Monitorization Checklist
Administrative personnel proactively monitor the system to identify processing errors and/or issues.
Understand the procedures in place and tools used to proactively monitor the system to identify processing errors and/or issues (i.e. BMC-Patrol, home-grown systems, Control/M, etc.) Ensure that the scheduled daily tasks checklist includes the following:
-Run transaction SM51 and check that all servers are up
-Run transaction RZ20 and check the CCMS alert monitor for alerts
-Run transaction SM50 and ensure that all work processes have a running or waiting status
-Run transaction SM13 and look for any failed updates. Check for lines with Err.
-Run transaction SM21 and check the system log. Check for: errors, warnings, security messages, abends, database problems, and any other different events.
-Run transaction SM12 and check for old locks. Check for entries from prior days.
-Run transactions SM04 and AL08 and review for any unknown or different user IDs and terminals.
-Run transaction ST22 and review and resolve dumps. Look for excessive numbers of dumps and look for dumps of an usual number.
-Run transaction ST03 and review workload statistics.
-Run transaction ST02 and review buffer statistics. Look for swaps.
-Run transactions AL02 and ST04 and review error log for problems.
Alternatively, administrators may execute transaction code SSAA (R/3 Administrative Activities), rather than executing all of the above transaction codes individually.
If CCMS is not used, determine the tools used to proactively monitor the system. Ensure that the tool is used effectively and that the tasks outlined above are monitored.
RZ20 or CCMS is a Central Monitor tool for monitoring the entire system landscape. We can create Alert to monitor specific devation of the system behaviour.

Purpose of ST02, ST03, ST04

hi,
Whats the Purpose of ST02, ST03, ST04. and what exactly we can do witg these T-codes
Regards
Ganesh

Hi Ganesh,
This transactions are statistic transactions, ST02 show you the memory utilization and buffers, ST03/ST03N show you the performance of the processes, ST04 is the SQL Server Database Monitor.
Hope this help!

Error while execting Tcodes ST04,ST03,DB12,DB02

Hi Experts,
I had installed QAS & DEV instances successfully on one windows host.Below are the syste details.
OS :- Windows 2003 64 bit Standard Edition

I am facing problem while executing transactions related to database i.e st04,st03,db12,db02.
After executing this transactions I received followng dumps.

2) Runtime Errors RAISE_EXCEPTION
Exception condition "DB_RELEASE_UNKNOWN" raised
Error analysis
A RAISE statement in the program "SAPLSORA" raised the exception
condition "DB_RELEASE_UNKNOWN".
Since the exception was not intercepted by a superior program
in the hierarchy, processing was terminated.
3)Runtime Errors BCD_ZERODIVIDE
Exception CX_SY_ZERODIVIDE
An exception occurred. This exception is dealt with in more detail below

Since the caller of the procedure could not have expected this exception
to occur, the running program was terminated.
The reason for the exception is:
In the current program "SAPLSKOM", an arithmetic operation ('DIVIDE',

Hi Markus,
I have seen the note#741119, it asks to apply pack SAPKB64004, but its says its valid for Release 640 only. My release is 640 currently:
Software Component Name     SAP_BASIS
Software Component Release     620
Support Package Level     0041
Highest Imported Support Package     SAPKB62041
Short Description of Software Component     SAP Basis Component
Support Package type     Basis Support Pkg.
My question is, can i apply the pack directly on release 620? The prequisite to this pack says, the release should be 640. This forum helped me a lot, hoping you guys will solve my this issue as well.
Regards.

SAP is running on Varitas cluster on two different nodes. One node is having SAP services and the another one Oracle services on it. Since the last week when we shifted the Oracle services from one node to another for monthly maintenace work, we are facing this problem.
Our system details are:
SAP 46C (kernel 46D_EXT) 32 bit
SuSe Linux 2.6.5-7 64 bit
Oracle 9.2.0.6.0
Can someone please help me on it.

Error message in ST04

Hi All,
I am getting following error message in st04 when the offilene database backup is run.
ORA-1109 signalled during: ALTER DATABASE CLOSE NORMAL...
System : R/3 4.7
DB : Oracle 9.2.0.6.0
Can anybody please tell me what exactly does it mean, and what can be the remedy for this?
Thanks.

perhaps your database was ALREADY down when you tried to shut it down.
this looks like a non-issue.

Data buffer(st04) is lower and lower

recently, i find such an information in our sap system using ST04. Following is message:

the quality value is lower an lower.
why? what should i do?
please help me ! thanks a lot

Hello,
it moght be due to u have set the data bufer size is too small so that more in and out is there ...this is the basic and primary reason for u r problem...

Retrieving historical data from new ST04

In the old ST04, you could get a nice, 3 month daily overview of key measures just by hitting "Previous Days". I use that in my performance analyses. With the new ST04, I have no idea how that's done. From my understanding, the new ST04 should give you historical data if you give an initial snapshot date that's far enough back. But I see no way to define the initial date as anything but "Database Start". SAP_COLLECTOR_FOR_PERFMONITOR has been running consistently for months. Programs RSORAHCL and RSORAVSH are scheduled to run hourly every day. So the history should still be there, and should be accessible. However, the documentation on the new DBACOCKPIT is very sketchy, as far as I've seen.
Can anyone either point me to some good documentation on this topic, or provide some hints. I'd very much appreciate it.
Thanks very much.
                                                   Gordon

Stefan,
The system I'm looking at, L6P, is on Basis 7.00 SP 13. For troubleshooting, I compared L6P to our G8P system , which is on Basis 7.00 SP 15.
One thing I found is that I can select some dates under the "Database Start" and "Up To Now" buttons on G8P, but not on L6P. I further found that in table TCOLL, RSORAHCL has all 7 days marked in G8P, but no days marked in L6P. That would explain why I see the dates in G8P, but not in L6P -- I need to flag the days for RSORAHCL in TCOLL.
So now, I know what I need to do to pick dates going back as far as what's in AWR, according to dba_hist_snapshot. I also see how I can change the snapshot interval and retention periods:
begin
   dbms_workload_repository.modify_snapshot_settings (
      interval => 20,
      retention => 22460
end;
for example. The data's in minutes, so I'd want interval = 1440 and retention = 902460 for 3 months of daily snapshot data.
However, I still don't see how I can actually see the history. I go into Statistical Information --> System Summary Metrics, select Metrics Datasource dba-view, and put in the dates I want. I get a lot of metrics, but I don't see a way to limit them to the sepcific ones I want (for data buffer hit rate, I think I'll need to get the physical and logical reads). How can I clean this up to show only what I need?
Thanks very much.
                                                                Gordon

Getting a Dump in ST04 DYNPRO_FIELD_CONVERSION

Hi All,
We have an ECC 6.0 running on Oracle 10.2.0.2 and os is SUN - OS
When i go to ST04 i get a dump in the system
DYNPRO_FIELD_CONVERSION
Screen name.............. "SAPLS_ORA_COCKPIT_2"
Screen number............ 0001
Screen field............. "ST04N_DATA-DBUFF_BUSYWAITS"
Error text............... "FX015: Sign lost."
I have applied the note 1227629 manually
i.e In Structure ST04N_DATA i saw the following data elements were having length as 12. and it was increased to 16.
DBUFF_LOGREADS
DBUFF_PHYSREADS
DBUFF_PHYSWRITES
DBUFF_BUSYWAITS
DBUFF_WAITTIME
and after that in SE80 selected function group S_ORA_COCKPIT_2 under the screen 0001 changed the length from 15 10 16 for fields DBUFF_LOGREADS
DBUFF_PHYSREADS
DBUFF_PHYSWRITES
DBUFF_BUSYWAITS
DBUFF_WAITTIME
however we still have the error. Any pointers would be helpful

Hello Rohith,
Thanks for the reply . I checked the note 1227629 its applicable from Basis Support pack 14onwards
and we are currently on 13 and the other notes 1137886, 1136458 tells us to increase the length to 16
and thats been done, The last note 1246251 shows a different Screen field

Hi,
Buffer: The first column shows the names of the buffers:
Four ABAP repository buffers.
The program, CUA, screen, and calendar buffers.
The table buffers.
Hit Ratio:
          A hit is when an object (such as a table, screen, or program) in the buffer is accessed. If the object has to be read from the database, the buffer access fails.
Allocated Size:
        The allocated size is measured in KB. It is different from the available buffer size because a part of the size is used for buffer management.
Freespace :
        Freespace is important for analyzing the buffer size. The space remaining in the buffer is displayed in KB and percentage of the available buffer size.
Number of Directories:
             Even though there is freespace in the buffer, objects may not always be loaded into the buffer because there are no more free directories. The Buffers Monitor displays the number of directories available for the buffer, and the number and percentage free. The buffer directories point to the location of the objects that are located in the buffer.
Swapping:
                When a buffer has insufficient freespace or free directories, it has to swap objects out of the buffer in order to load a new object. The column Swap shows how many objects have been swapped out since system startup.
Database Accesses
                      When an object cannot be read from the buffer, the database has to be accessed. The number ofdatabase accesses is displayed in the last column of this screen.

Running DBMON for ST04 Statistics?

Is everyone running DBMON for ST04 statistics? At one time it slowed down general database activity because it was so busy collecting statistics. We are checking to see if that is still true.
The main reason for the question is whether it could be slowing down our CRM 7.0 database accesses.
Thanks much,

Hi Margie,
there is good and bad news ...
The good news is, that the system will no longer hang with the new setup - it needs a few ressources, but not really a lot.
The bad news is, that part of the data is not really reliable as the "1ms" SQLs are typically faster than that ...
Therefore, I prefer to directly use the OpsNav Plan Cache and then deactivate this within SAP.
That is really a great feature !!!
