5 1 0:Directory Layout

Overview

SEP sesam always creates two directory structures during installation – one for static data and one for variable data. Both structures can be either in the same main directory or in two different directories. On Unix, the installation directories are represented in the file /etc/sesam2000.ini.

SEP sesam directory aliases

Directory aliases are used to refer to the specified paths in the default SEP sesam directory structure.

<SESAM_BIN>

Refers to the part of the directory structure of a Linux package installation in which the unchangeable files (e.g., binaries) are stored. Path /opt/sesam can not be selected during installation.

<SESAM_VAR>

Refers to the part of the directory structure of a Linux package installation in which the variable files (e.g., configuration and log files) are stored. Path /var/opt/sesam/var is not arbitrary during installation.

<SESAM_ROOT>

Refers to the install location of the SEP sesam file structure for a Linux tarball or a Windows installation. This means that both tarball and Windows installations show <SESAM_BIN> and <SESAM_VAR> on the same location in the file system (referred to as <SESAM_ROOT> here). The install directory must be specified during a tarball installation (default path is /opt/sesam) and also during Windows installation (default path is C:\Program Files\SEPsesam).

SESAM_BIN directory

This directory contains all unchanged files, such as programs, templates, etc. The following directory structure is created during SEP sesam installation:

What	Where
Database components	SESAM_BIN/bin/db
GUI components	SESAM_BIN/bin/gui
Dedupe components	SESAM_BIN/bin/sds
Server components	SESAM_BIN/bin/sesam
Communication components	SESAM_BIN/bin/sms
Templates incl. raw versions for first installation	SESAM_BIN/skel
Templates for programmable interfaces	SESAM_BIN/skel/templates

SESAM_VAR directory

This directory contains all changeable data, such as SEP sesam database, protocols and log files. The following directory structure is created during setup:

What	Where
Database	SESAM_VAR/db[_pg]
SEP sesam database backup	SESAM_VAR/db[_pg]/backup
Configuration files	SESAM_VAR/ini
SSH keys for control communication	SESAM_VAR/ini/sm_ssh
SSL certificates for data transfer	SESAM_VAR/ini/ssl
Notification and metadata logs	SESAM_VAR/lis
Main directory for log files	SESAM_VAR/log
Logs of the Pre- and Post- jobs	SESAM_VAR/prepost
Status and daily logs	SESAM_VAR/prot
Media action logs	SESAM_VAR/prot/media
SEP sesam interface logs	SESAM_VAR/prot/notification
Restore logs	SESAM_VAR/prot/restore
Temporary files for transient storage	SESAM_VAR/tmp
Temporary files for longer storage	SESAM_VAR/work
Mountpoint for VMware and other single item restore tasks	SESAM_VAR/work/mnt

Example

 C:\Program Files\SEPsesam

	Note
	As of SEP sesam version 5.1.0 Apollon, LIS files in SESAM_VAR/lis directory are organized into date-based subdirectories. A sub-directory is created for every (SEP sesam) day, where files for that day are stored.

Sample directory structure

The following is common SEP sesam directory layout after an RPM or DEB installation on Linux. The programs are located in /opt/sesam, the files are in /var/opt/sesam:

 barometrix:~ # find /opt/sesam/ /var/opt/sesam/ -type d
 /opt/sesam/
 /opt/sesam/bin
 /opt/sesam/bin/db
 /opt/sesam/bin/gui
 /opt/sesam/bin/gui/html
 /opt/sesam/bin/sesam
 /opt/sesam/bin/sms
 /opt/sesam/skel
 /opt/sesam/skel/db
 /opt/sesam/skel/templates
 ###
 /var/opt/sesam/
 /var/opt/sesam/var
 /var/opt/sesam/var/ini
 /var/opt/sesam/var/ini/root
 /var/opt/sesam/var/log
 /var/opt/sesam/var/log/db
 /var/opt/sesam/var/log/lgc
 /var/opt/sesam/var/log/sms
 /var/opt/sesam/var/tmp
 /var/opt/sesam/var/work
 /var/opt/sesam/var/work/smslis
 /var/opt/sesam/var/work/info
 /var/opt/sesam/var/work/ctl
 /var/opt/sesam/var/work/sem
 /var/opt/sesam/var/times
 /var/opt/sesam/var/lis
 /var/opt/sesam/var/not
 /var/opt/sesam/var/qm
 /var/opt/sesam/var/glbv
 /var/opt/sesam/var/prepost
 /var/opt/sesam/var/prot
 /var/opt/sesam/var/sel
 /var/opt/sesam/var/db
 barometrix:~ #                      

 /opt/sesam/bin
 /var/opt/sesam

The /var/ini directory contains the following initialization files:

sm.ini
sm_java.policy
sms.ini
odbc.ini
debug.ini
sm_lic.ini
stpd.ini
