Was ist der SEP sesam-Tageswechsel?

Der SEP sesam Tageswechsel (Newday) ist ein vordefinierter SEP sesam Tageswechsel-Termin, der den Sicherungsterminkalender zurücksetzt und vom SEPuler verwaltet wird. Der Tageswechsel wird von SEP sesam verwendet, um seine Datenbank neu zu ordnen und eine ununterbrochene Aktivität der SEP sesam Prozesse zu ermöglichen. Daher darf er niemals vollständig deaktiviert werden, da es sonst dazu führt, dass SEP sesam nicht mehr richtig funktioniert. Der SEP sesam Tageswechsel gibt Systemadministratoren die Flexibilität, Sicherungsroutinen auf die Zeit nach Mitternacht auszudehnen und das Sicherungsdatum des Vortages beizubehalten. Dies ist sehr nützlich, wenn die Computer, die Sicherungen benötigen, die Zeitspanne zwischen Tagesende und Mitternacht überschreiten. Details finden Sie unter Tageswechseltermin (Newday).

Gibt es eine Übersicht aller SEP sesam-Dienste?

Es gibt verschiedene Dienste, je nachdem ob es sich um einen SEP sesam Server, einen SEP sesam Client oder einen SEP sesam Remote Device Server handelt.

Diese Dienste können im SEP sesam Installationsverzeichnis <SESAM_ROOT>/bin/sesam gefunden werden. Um den Status der Dienste zu überprüfen, verwenden Sie die folgenden Befehle:

Linux/UNIX

./sm_main status

Windows

sm_main status

SEP sesam Server services

sm_qm_main   SEP sesam main processes, provides also the qm service
sepuler      SEP sesam event calendar to control all tasks
db           SEP sesam database services
qm           Queue manager, administers backups, restores and devices
rmi          server part of the graphical user interface (GUI)
sms          read/write of SEP sesam media
stpd         linking protocol from the SEP sesam Client to the SEP sesam Server
passd        security administration for SEP sesam
ctrl         linking protocol from the SEP sesam Server to the SEP sesam Client
sshd         secure linking protocol from the SEP sesam Server to the SEP sesam Client

SEP sesam Client services

sm_qm_main    SEP sesam main processes
ctrl          linking protocol from the SEP sesam Server to the SEP sesam Client
sshd          secure linking protocol from the SEP sesam Server to the SEP sesam Client

SEP sesam Remote Device Server services

sm_qm_main  SEP sesam main processes
ctrl        linking protocol from the SEP sesam Server to the SEP sesam Client
sms         read/write of SEP sesam media
stpd        linking protocol from the SEP sesam Client to the SEP sesam Server
passd       security administration for SEP sesam
sshd        secure linking protocol from the SEP sesam Server to the SEP sesam Client

In Backups by state, what do the flags in the column Level mean?

The first letter shows the backup level/type:

F/D/I/C:  Backup level (full, differential, incremental, copy)
N:        SEP sesam NEWDAY
S:        SEP sesam startup
X:        SEP sesam command event

The second letter is used when a database backup is performed. It has no significance for the regular Path backups.

H:  Hot - online backup of a database
C:  Cold - offline backup of a database

What happens when I set a profile?

By setting a profile:

  • the <SESAM_ROOT>/bin and <SESAM_ROOT>/var/db/ directories (and their subdirectories) are added to the "$PATH" environment variable so that SEP sesam commands can be executed globally,
  • you do not need to be in the actual run directory.

To set a profile, depending on your operating system, proceed as follows:

On Linux/UNIX

Go to the directory <SESAM_VAR>/var/ini and call:

. sesam2000.profile

Do not forget the dot and the space!

Alternatively, use:

source sesam2000.profile
Information sign.png Anmerkung
This sets the profile only for the current session. To set it permanently under Linux, see How do I configure SEP sesam profile to run automatically during login?

On Windows

Open a command window, then go to the directory <SESAM_ROOT>\var\ini and call:

sm_prof.bat

Alternatively, use the link <SESAM_ROOT>\var\ini\sm_prof.bat.lnk.

Why does the SEP sesam GUI create so many Java processes under Linux?

On some Linux Systems, the threads created by the SEP sesam GUI are shown in the process table. These are not real processes but only threads. There is a large number of processes because Java creates threads for all objects with Listener functionality.

Why does SEP sesam Server use so much disk space on the local hard disk?

One of the essential advantages of SEP sesam is that not all information is filed in a database but, instead, in simple text files. The largest files are usually the *.lis files which contain information about the backup's unique files and are used by the restore wizard to select and restore unique files. *.lis files are stored in the following directories:

Linux/UNIX

/<SESAM_ROOT>/var/lis

Windows

C:\<SESAM_ROOT>\var\lis

You can compress the files as follows:

  1. Set the SEP sesam profile.
  2. On Linux/UNIX: source /var/opt/sesam/var/ini/sesam2000.profile On Windows: C:\<SESAM_ROOT>\var\ini\sm_prof.bat
  3. Use the sm_newday command to run file compression immediately. The files will be compressed directly by the NEWDAY schedule. As predefined in the command, *.lis files are not compressed immediately but three days after they are created. This is because most restores are triggered within three days after a backup.

All *.lis files are converted into a compressed file format and are uncompressed by SEP sesam automatically whenever necessary.
