BR1049W Not enough free space in /oracle/sid/sapdata5/sr3_63
for total maximum size of all database files of tablespace PSAPSR3
located on this disk volume, missing at least 272.222 MB
-------------------------------



"Knowledge is power, but it is only useful if it is shared!"


A sample backup schedule might look like:
1. Hourly - brarchive backup of archive logs
2. Daily - brbackup backup of full database
3. Monthly - file system backup of /sapmnt/, including SAP executables and profile data, and /oracle/SID/_/dbs & network ---making sure you get Oracle/SAP init files and network files (tnsnames.ora, listener.ora,\nnames.ora, etc., though you might have relocated these files elsewhere), & /usr/sap/trans directory.
4. Quarterly - Oracle export performed to tape.

This schedule is good enough for a small system landscape with an orgnanization. If the landscape is huge, then you need to re-think about how backup is done. An integration with Oracle RMAN is good for running incremental backup. This will reduce the number of media needed for running daily full online backup - storage optimization

-----------------------------------
SAP gives you standard Basis role :

SAP_BC_BASIS_ADMIN
SAP_BC_DB_ADMIN or SAP_BC_DB_ADMIN_ORA if you are using Oracle
SAP_BC_CLIENTCOPY
SAP_BC_BATCH_ADMIN
SAP_BC_TRANSPORT_ADMINISTRATOR
SAP_BC_SPOOL_ADMIN

copy that to ZSAP_BC_BASIS_ADMIN, ZSAP_BC_DB_ADMIN, ZSAP_BC_DB_ADMIN_ORA, etc. then modify that Zrole if you need to add or remove tcode and/or authorization objects. and finally assign to your consultant username.

but you have to monitor your consultant for what they did on your production server using STAD.

Setting Your Shell Prompt

http://hell.org.ua/Docs/oreilly/unix/upt/ch07_01.htm

Basics of Setting the Prompt

The prompt displayed by your shell is contained in a shell variable (6.8) called prompt in the C shell and PS1 in the Bourne shell. As such, it can be set like any other shell variable. [bash and tcsh have plenty of extra features for those two variables. There are examples in later articles. -JP]

So, for example, if I wanted to change my C shell prompt to include my login name, I might put the following command into my .cshrc file:

set prompt="tim % "

(It's helpful to leave the % at the end so that it remains obvious that this is a C shell. The space after the % makes the command you type stand out from the rest of the prompt.)

Or if I wanted to put in the name of the system I was currently logged in on, I might say:

`...` uname -n



set prompt="`uname -n` % "

If I wanted to include the history number for each command, (11.1) I'd say:

set prompt="\! % "

Or if I wanted all three things:

set prompt="tim@`uname -n` \!% "

This will give me a prompt like this:

tim@isla 43%

AİX SİSTEMLERDE DİSK BOYUTUNUN ARTTIRILMASI

Aix sistemlerde df -g komutu ile disk durumlarını görebiliyoruz. Kontrollerimizde disk alanı yetersizliği tespit edersek disklere boş alan eklenmesi ihtiyacı doğmuş demektir (%100, %99, %98 ...vb).

Disk büyütme işlemlerinde öncelikle yapılması gereken ilgili Aix sisteme Ssh ile bağlanılması gerekmektedir. Bağlantı yapıldıktan sonra df -g komutu ile disklerin durumlarını kontrol ederiz.

Görüleceği üzere bir partitionın durumu %98 lere gelmiş. İlerleyen tarihlerde dolduğunda performans ve başka sorunlarla karşılaşılabilir. Bu nedenle bu alana boş alan eklemeliyiz.

Öncelikle boş alanımızın olup olmadığına bakıyoruz. Bu işlemden önce volume groupun karakteriksel özellikleri listelemememiz gerekiyor.. Bu sayade volume groupta boş alan varmı bakacağız. Lsvg komutunu veriyoruz.

Görüleceği üzere rootvg partition unda 92416 Mb, sapvg partitionunda ise 45824 Mb lık boş yerimiz var. 2000Mb eklemeye karar veriyoruz ve disk alanı ekleme komutumuzu veriyoruz.

root@asprod:/> chfs -a size=+2000M /sapmnt/ASP

Bu komut ile 2000Mb alanı /sapmnt/ASP alanına ekliyoruz. Eğer çıkartmak istiyorsak komutta yapacağımız değişiklik size=-2000M dir. Yani artı yı eksi yapıyoruz. Daha sonra disk alanlarını df –g komutu ile incelediğimizde /sapmnt/ASP alanının 2000 Mb arttığını görebiliriz.

AİX SİSTEMLERDE PERFORMANS KONTROLÜ

Aix sistemlerde belirli zamanlarda performans kontrolü yapılması gerekebilir. Sistemde oalbilecek yavaşlıklarda yada bir darboğaz ile karşılaşıldığında system performansının control edilmesi problemin tespit edilmesinde önemli derecede yardımcı olabilir.

Aix sistemlerde de Linux sistemlerdeki top komutunun bir benzeri olan topas komutu kullanılmatadır. Aix sisteme telnet bağlantısı yapıldıktan sonar komut satırında topas komutu çalıştırılır ve aşağıda göreceğiniz ekran karşınıza gelir.

Bu ekranda sol alt köşede çalışan processlerin PID numaraları, Cpu kullanımları ve procesi kullanan user gibi bilgiler yer almaktadır.

Ortadaki ekranda diskler hakkında bilgiler, en üst soldaki ekranda sistemin durumu, idle gibi bilgiler yer almaktadır.

Eğer sistemde bir yavaşlık varsa ve topas komutu ile system performansı test edildiğinde Cpu kullanım alanına bakılmalıdır. Cpu yu aşırı kullanan bir process varsa bunun ne olduğu üzerine araştırmalar yapılabilir.

SAP Sistem sapsys kullanıcısı Lock administrator No. 032 process inde “Lock table overflow” hatası.

SAP Sistem sapsys kullanıcısı Lock administrator No. 032 process inde “Lock table overflow” hatası.

Çözüm;
Lock table enqueue sunucu üzerinde bellekte bulunmaktadır. Enque/table_size büyüklüğü il bu değer KB cinsinden değiştirilebilir.

Raporlu olanlar dikkat

506 sayılı Kanunun 37 inci maddesi hükmü gereğince istirahatlı bırakılan sigortalılarımıza istirahatın başladığı üçüncü günden itibaren geçici iş göremezlik ödeneği ödenmekte olup,506 sayılı Sosyal Sigortalar Kanununda geçici iş göremezlik ödeneği ödenmeyen 2 gün için işverence ödeme yapılıp yapılmayacağına ilişkin bir hüküm bulunmamaktadır.

SAP lock table overflow

lock table overflow hatası çok almaya başladıysanız ilk yapacağınız iş
sm12->extrac->statistics
Lock Owner Table, Size alanın dolu mu?
eğer doluysa rz10 ile gidip enque ile ilgili parametreleri kontrol etmeniz gerekir.
ilk olarak enque/table_size alanını değiştirmelisiniz
max değeri 102400 eğer max değerini yazdığınızda hata alıyorsanız;
enque/process_location = REMOTESA parametresini değiştirmelisiniz.
bu değişiklikleri yapmadan önce uygulamacı arkdaşlar ile konuşup uygulamada problem olup olmadığını çek ederseniz uygun olur.

eğer Lock Owner Table, Size dolmuyorsa table lock lı olduğundan hatayı veriyordur. bunda yapılacak bir şey yok.

OTOMATİK KİLİTLEME
Bazı veri tabanı yönetim sistemleri, tablonun değişimine sebebiyet verecek herhangi bir komut (INSERT;UPDATE;DELETE) uygulandığı zaman, o tablo üzerinde otomatik olarak EXCLUSIVE kilitleme oluşturur. Bu kilitleme herhangi bir COMMIT yada ROLLBACK komutu ile ortadan kalkacaktır.
Örnek : LOCK TABLE X IN SHARE MODE;
X tablosu SHARE MODE’da kilitleniyor. Diğer kullanıcılar sadece okuma yapabilir.
Örnek : LOCK TABLE Y IN EXCLUSIVE MODE;
Y tablosu EXCULUSIVE MODE’da kilitleniyor. Diğer kullanıcılar sadece okuma yapabilir. Ve Y tablosu üzerinde kilitleme yapılamaz
----------------------------------
Locking a Table: Example

The following statement locks the employees table in exclusive mode but does not wait if another user already has locked the table:

LOCK TABLE employees
IN EXCLUSIVE MODE
NOWAIT;


The following statement locks the remote employees table that is accessible through the database link remote:

LOCK TABLE employees@remote
IN SHARE MODE;

TemSe

TemSe is basically a data store that is used for storing temporary sequential data/objects.
Such data/objects are not required to be held permanently in the system. A few TemSe objects/data among others are stated below:

Spool Data
Job Logs
Objects from HR, Fin, etc. applications

Storage Location for TemSe:

Each TemSe object has a header entry in table TST01 and the actual object, which can be stored on the file system (OS Level-performance advantage) or table TST03 (DB Level- backup by default for being a part of DB).

Let’s look how the different objects are preferred to be stored generally.

Spool Data: By default stored in TST03, along with entries in TSP01 (for Spool Requests) and TSP02 (for Output Requests). However, we do have an option of selecting the storage of these objects that can be defined through the profile parameter: rspo/store_location (db value: stored in table TST03, G value: stored in global dictionary in OS)
Job Logs: Stored in File system on OS Level.
HR Objects, etc.: Stored in TST03

Managing TemSe Objects:

TemSe is not an archiving system.

And so we need to always make sure that the number of objects and memory allocation do not increase in the system. We need to delete objects that are no longer required. Deletion can be done as follows:

i. Deleting spool requests either by SPAD (if less in number) or else running report RSPO0041
ii. Deleting job logs through report RSBTCDEL. (Deleting job logs directly might lead to inconsistencies. Instead, it is better to delete the batch jobs responsible for the same)
iii. If we are very sure about the TemSe objects that need to be deleted, we can run the report RSTS0022. However, this can lead to inconsistencies while deleting spool objects as this report clears entries only in table TST01 and not the corresponding entries in TSP01/TSP02. Hence, after using this report, best practice is to perform consistency checks on Spooler and TemSe.

In case of spool requests, print list archiving is possible though.

Also, TemSe objects have a retention period. We need to check if any objects have unlimited retention period. This Expiry Time can be checked as below:

SP12 t-code, then from the menu bar selects Gotoà TemSe Contents.

This screen will get us to all the matching objects. Thereafter, double clicking any row i.e. particular object name gives us all the details about the object (e.g. Object Name, Creator, Creation Date, Last Changed on, Expiry Date, Where the object is stored, its record type, size, client, etc.)

TemSe cannot manage objects that require more than 2 GB storage space: This is irrespective of the storage location used i.e. DB or OS. Also, the total number of objects in TemSe varies from 30k to 40k generally.

We can check the memory allocation for TemSe through SP12 T-Code.
From the menu bar, we need to select TemSe Data StorageàMemory allocation.

This gives us an overview of Storage space available in Database and file system for each client. It has further sections, detailing the TemSe object name and the amount of space used across DB/ file.

OS07/ST06: System monitor
The CPU utilization (CPU Utilization user) should not constantly range above 60
to 70% per CPU.
it is recommended that not more than 20% of the physical main memory should be
swapped per hour.
Thus, in a system with 4 GB of memory, swap rates of up to 200
KB/second are acceptable. But in general you can say the smaller the swap rate, the better

The utilization of the slowest hard disk (Disk with highest response time value in the
Response time group) should range below 50%. If that is not the case, the hard disk may be
overloaded.

LAN Errors in/s and LAN Errors out/s
should be 0

LAN Collisions greater than 0

SAP Oracel Parametreleri Uyarıları

-QUERY_REWRITE_ENABLED parametresi true olursa ana tablonun materialized view i varsa sorguda mv e bakıyor. false olursa sorgu yaparken mv in belirtilmesi gerekir. eğer güncel veriler istiyorsanız materialized view yerine ana tabloyu sorgulamanız daha doğru olur. mv in avantajı sorgularda performans sağlayacaktır.

-REPLICATION_DEPENDENCY_TRACKING parametresi replike çalışan sunucularınız varsa true yapmanız gerekecektir. aksi takdirde false olması daha doğru olur.

-STATISTICS_LEVEL parametresin 10 g ile birlikte default değeri typical geliyor. sadece tablo gözlemleme amaçlı düşünmeyelim. AWR, ASSM, ADDM gibi onemli raporlama alanlarının takibi ile de sorumlu. metalink 252597.1

-STAR_TRANSFORMATION_ENABLED parametresi CSO sorguya dönüştürülmesine karar veriyor. SQL kalıpların alt sorgulara bölünerek Bitmap indexlerden yararlanılmasını sağlar. perfomans için true olmalıdır.

-SHARED_POOL_SIZE parametresi default değeri “0” da bırakılmışsa bu demektedir ki sga target ile belirlediğimiz alanı içerisinden shared pool alanına MMAN arka planda karar veriyor. eğer default değerini değiştirirsek default değerinin altına inmez.

-PARALLEL_EXECUTION_MESSAGE_SIZE parametresi default değeri 2kb dir. Slave process ile coordinator arasındaki buffer miktarını belirler. Eğer mesajlar büyükse parçalanır. Bu azda olsa performans kaybına neden olur. 8kb yapılabilir.

-OPTIMIZER_FEATURES_ENABLE parametresi ile db nin hangi release sahip olduğu belirtilir.

-LOG_BUFFER parametresi Redo log alanın büyüklüğünü belirler. Büyük olması i/o maliyetini düşürür.

-CRITICAL_TABLESPACE tablespace alanlarınıda kritik seviyede bulunan varsa uyarı verir.
