sql server: restore many transactionlogs

example of restoring sql server transaction logs to a full backup: beispiel einiger Befehlszielen um transaktionslogs wiederherzustellen:
RESTORE LOG [CrmBak] FROM DISK = N'E:\SqlServerBackup\CRM\CRM_backup_2014_01_01_230431_6398282.trn' WITH FILE = 1, NORECOVERY, NOUNLOAD, STATS = 10
RESTORE LOG [CrmBak] FROM DISK = N'E:\SqlServerBackup\CRM\CRM_backup_2014_01_02_230438_1759387.trn' WITH FILE = 1, NORECOVERY, NOUNLOAD, STATS = 10
RESTORE LOG [CrmBak] FROM DISK = N'E:\SqlServerBackup\CRM\CRM_backup_2014_01_03_230429_5963993.trn' WITH FILE = 1, NORECOVERY, NOUNLOAD, STATS = 10
to generate the restore command lines I used commandline: dir >dir.txt then with notepad++ I removed the date /time columns by pressing alt+marking with mouse, then used edit/Column editor to insert restore.... before the filename and ' WITH FILE=1 ... after the filename
um die Restore Befehle zu erzeugen, verwendetete ich den DOS BEfehel DIR: dir> dir.txt dann mit notepadd++ mit gedrückter alt taste mit der maus die unerwünschten spalten markeiren und löschen, dann mit edit / Column editor fügte ich vor dem dateinamen restore ... und nach dem DAteinamen 'WITH FILE=1 ... hinzu

wenn ein transaktionslog fehlt oder das zugrundeliegende full backup nicht in den Zeitraum des transaktionslogs fällt erhält man: Meldung 4305, Ebene 16, Status 1, Zeile 1 Das Protokoll in diesem Sicherungssatz beginnt bei LSN 29111000000034100001. Diese liegt für eine Anwendung auf die Datenbank nicht weit genug zurück. Eine frühere Protokollsicherung, die LSN 29015000000200600001 einschließt, kann wiederhergestellt werden. Meldung 3013, Ebene 16, Status 1, Zeile 1 RESTORE LOG wird fehlerbedingt beendet.

Common linux commands you need to use in single-user modes are located under this directory.
Commands used by all the users of the system are located here.
For example: ps, ls, ping, grep, cp.
3. /sbin – System Binaries

Just like /bin, /sbin also contains binary executables.
But, the linux commands located under this directory are used typically by system aministrator, for system maintenance purpose.
For example: iptables, reboot, fdisk, ifconfig, swapon
4. /etc – Configuration Files

Contains configuration files required by all programs.
This also contains startup and shutdown shell scripts used to start/stop individual programs.
For example: /etc/resolv.conf, /etc/logrotate.conf
5. /dev – Device Files

Contains device files.
These include terminal devices, usb, or any device attached to the system.
For example: /dev/tty1, /dev/usbmon0
6. /proc – Process Information

Contains information about system process.
This is a pseudo filesystem contains information about running process. For example: /proc/{pid} directory contains information about the process with that particular pid.
This is a virtual filesystem with text information about system resources. For example: /proc/uptime
7. /var – Variable Files

var stands for variable files.
Content of the files that are expected to grow can be found under this directory.
This includes — system log files (/var/log); packages and database files (/var/lib); emails (/var/mail); print queues (/var/spool); lock files (/var/lock); temp files needed across reboots (/var/tmp);
8. /tmp – Temporary Files

Directory that contains temporary files created by system and users.
Files under this directory are deleted when system is rebooted.
9. /usr – User Programs

Contains binaries, libraries, documentation, and source-code for second level programs.
/usr/bin contains binary files for user programs. If you can’t find a user binary under /bin, look under /usr/bin. For example: at, awk, cc, less, scp
/usr/sbin contains binary files for system administrators. If you can’t find a system binary under /sbin, look under /usr/sbin. For example: atd, cron, sshd, useradd, userdel
/usr/lib contains libraries for /usr/bin and /usr/sbin
/usr/local contains users programs that you install from source. For example, when you install apache from source, it goes under /usr/local/apache2
10. /home – Home Directories

Home directories for all users to store their personal files.
For example: /home/john, /home/nikita
11. /boot – Boot Loader Files

Contains boot loader related files.
Kernel initrd, vmlinux, grub files are located under /boot
For example: initrd.img-2.6.32-24-generic, vmlinuz-2.6.32-24-generic

opt stands for optional.
Contains add-on applications from individual vendors.
add-on applications should be installed under either /opt/ or /opt/ sub-directory.
14. /mnt – Mount Directory

Temporary mount directory where sysadmins can mount filesystems.
15. /media – Removable Media Devices

Temporary mount directory for removable devices.
For examples, /media/cdrom for CD-ROM; /media/floppy for floppy drives; /media/cdrecorder for CD writer
16. /srv – Service Data

srv stands for service.

access auf ODBC Backend umstellen - move from Access to ODBC Backend

Beim Umstellen eines reinen Access Backends auf ein ODBC Backend (z.b. Oracle over ODBC) gibt es folgendes zu beachten:
1) recordset Find Operationen sind extrem langsam, da zuerst die ganze Tabelle in den Access Speicher geladen wird und dort dann gesucht wird. Besser das Recordset gleich mit der richtigen WHERE Bedingung aufmachen:
    Set rs= New ADODB.Recordset
    rs.Open "select * from mytable where ID='" & 923 & "'", connection, adOpenKeyset, adLockReadOnly
    statt:
    rs.Find "ID= '" & 923 & "'", , adSearchForward, adBookmarkFirst

2) wenn man Sätze mit rs.AddNew / rs.Update hinzufügt, so werden diese zwar im Backend hinzugefügt aber nicht im Recordset = nochmal nachladen

Entity Framework liest statt unterscheidlicher Datensätze mehrfach den gleichen aus

Wenn bei einer view der Primary Key fehlt, so liefert das Entity Framework eventuell immer den gleichen Datensatz.
Man muß dann einen künstlichen Primary Key scahffen, z.b. mittels
IsNUll(ROW_NUMBER() OVER(ORDER BY Lastname, FirstName),-1) AS 'ID'
 und andere Spalten, die als Primary Key herangezogen werden mit NullIf(keyKandidat,-1) als Kandidat für den Primary Key aussschließen. Dann die View im Model löschen und neu hinzufügen.
