Pentru un backup complet al sistemului:

rsync –aAv –-exclude={"/bkp/*","/mnt/*","/media/*","/tmp/*"} / /bkp

Se va copia tot folderul /, mai putin folderele care au fost specificate pentru excludere, in folderul destinatie /bkp.

Pentru copierea parolei utilizatorului GEORGE.S din clientul 300 peste acelasi utilizator din clientul 200 se poate utiliza urmatorul sql query:

UPDATE
    T200
SET
    T200.BCODE = T300.BCODE,
    T200.PASSCODE = T300.PASSCODE
FROM
    lid.USR02 AS T200
    INNER JOIN lid.USR02 AS T300 ON (T200.BNAME = T300.BNAME AND T300.MANDT = '300')
WHERE
    T200.MANDT = '200' AND T200.BNAME = 'GEORGE.S';

Pot fi vizualizate/sterse mai multe mesaje simultan: -d123 -v456 -d567

Daca se constata ca pe server-ul de email ajung o serie de emailuri bounce ciudate ca raspuns la unele mesaje care nu au putut fi livrate catre destinatar, este foarte posibil ca un cont de email sa fie compromis. Acelasi motiv poate sa fie si la baza faptului ca server-ul de email este listat intr-o baza de date antispam (ex: www.barracudacentral.org).

1. Se verifica daca este instalat Java

lorand@ubuntu:~$ java -version

2. Se adauga repository-ul pentru instalarea Java si apoi se instaleaza Java:

lorand@ubuntu:~$ sudo add-apt-repository ppa:webupd8team/java
lorand@ubuntu:~$ sudo apt-get update
lorand@ubuntu:~$ sudo apt-get install oracle-java8-installer

4. Se instaleaza SAPGUI (poate fi descarcat de aici:  7.40 sau 7.50):

lorand@ubuntu:~$ sudo java -jar /home/lorand/Desktop/PlatinGUI740Linux_4.JAR

5. Se ruleaza SAPGUI

lorand@ubuntu:~$ cd /opt/SAPClients/SAPGUI7.40rev4/bin
lorand@ubuntu:~$ ./guilogon

6. Se configureaza conexiunea la server (tab-ul Advanced)

conn=/H/xxx.xxx.xxx.xxx/S/3200

7. Pentru dezinstalare se foloseste comanda

java -jar /home/lorand/Desktop/PlatinumGUI740Linux_4.JAR uninstall

tsconfig -> Restrict each user to a single session (trebuie debifat)

In ultimele zile au aparut cateva probleme la printarea din SAP, in special la colegii care listeaza mai multe tipuri de documente pe imprimante diferite. De asemenea, problemele au aparut si la colegii care utilizeaza Windows 10. Pentru a rezolva problema au fost facute cateva teste si configurari la imprimantele din SAP.

Din Local Group Policy se poate restrictiona un utilizator sa se logheze local.

Se porneste editorul Local Group Policy din linie de comanda: gpedit.msc

Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment. Aici se gaseste politica Deny log on locally. Grupurile sau utilizatorii adaugati in aceasta politica nu se vor putea autentifica local si nu vor apare in ecranul de login.

Dupa instalarea unor update-uri in Windows 7, pe unele calculatoare nu au mai rulat anumite fisiere executabile. Eroarea afisata era:

The application was unable to start correctly (0x0000005)

Solutia a fost dezinstalarea ultimelor update-uri, doar ca nici Installed updates nu putea fi accesat. In schimb, Update history afisa lista de update-uri instalate impreuna cu data instalarii fiecaruia. In felul acesta au fost identificate ultimele update-uri instalate.

Fiecare update a fost dezinstalat folosind comanda:

wusa /uninstall /kb:3127220

In scriptul JS:

$('#upload').uploadify({
	'scriptData': { 'session': '<?php echo session_id(); ?>' }
});

In scriptul PHP:

if (array_key_exists('session_id', $_REQUEST))
	session_id($_REQUEST['session_id']);

• se alege sectiunea Drivers & Downloads
• se alege Fujitsu Server PRIMERGY
• se alege PRIMERGY RXxxx
• se alege PRIMERGY RX300 S6
• se alege sistemul de operare dorit (in cazul meu Windows Server 2008 x64)

Fujitsu ServerView RAID Manager poate fi descarcat de la adresa http://support.ts.fujitsu.com/, unde se alege versiunea sistemului de operare, apoi se alege SAS RAID, apoi tipul de controller RAID (in cazul meu D2616) si se descarca ServerView RAID Manager.

Dupa instalarea programului, acesta poate fi accesat printr-o interfata web la adresa https://server-addr:3173. Pentru accesarea ServerView RAID Manager este necesara instalarea Java, minim versiunea 7. De asemenea, in firewall trebuie deschis portul 3173.

Daca browser-ul afiseaza mesaje de avertizare cu privire la lipsa unui certificat, se urmeaza instructiunile din documentatia programului, la adresa https://server-addr:3173/public/help/en/index.htm

Pasul 1

• Control Panel -> Windows Update -> Installed updates -> KB3035583 (uninstall)
• Control Panel -> Windows Update -> Hide KB3035583

1. Autentificare in sistemul in care se doreste copierea datelor (sistemul destinatie)
2. Se ruleaza tranzactia SCC9 (Copie client)
3. Se completeaza informatiile necesare:
   • Profil: SAP_ALL
   • Client sursa: LIPCLNT500
4. Se completeaza parametrii pentru Parallel Processes
   • Goto -> Parallel Processes
   • Maximum number of processes: 12 (se recomanda cate 2 procese pentru fiecare procesor al bazei de date, iar pentru copia de client remote se pot utiliza cate 3 procese)
   • Logon/Server Group: parallel_generators
5. Programare executare copie in background
6. Jurnalul de activitati poate fi consultat in tranzactia SCC3

Important: la momentul inceperii copiei de client, joburile programate de pe clientul sursa vor fi oprite/suspendate automat. Acestea pot fi oprite si manual folosind tranzactia SE38 si ruland programul BTCTRNS1. Dupa efectuarea copiei de client aceste joburi trebuie repornite/reactivate manual ruland programul BTCTRNS2 in tranzactia SE38.
