For MAXDB and liveCache Version 7.5 (or higher) the SAP_DBTech.ini file does not contain sections [Installations] , [Databases] and [Runtime]. These sections are stored in separate files Installations.ini, Databases.ini and Runtimes.ini in the IndepData path /sapdb/data/config.

A sample SAP_DBTech.ini, Installations.ini, Databases.ini and Runtimes.ini for a host with a liveCache 7.5 (LC2) and an APO 4.1 using a MAXDB 7.5 (AP2):from /var/spool/sql/ini/SAP_DBTech.ini:

[Globals]

IndepData=/sapdb/data

IndepPrograms=/sapdb/programs

from /sapdb/data/config/Installations.ini: [Installations] /sapdb/LC2/db=7.5.0.15,/sapdb/LC2/db /sapdb/AP2/db=7.5.0.21,/sapdb/AP2/db from /sapdb/data/config/Databases.ini: [Databases]

LC2=/sapdb/LC2/db.

M750021=/sapdb/AP2/db

from /sapdb/data/config/Runtimes.ini: [Runtime] /sapdb/programs/runtime/7500=7.5.0.0

NOTE: The[Globals] section is commonly shared between LC1/LC2 and AP1/AP2. This prevents setups that keep the directories of LC1 and AP1 completely separated.

The following directories are of special interest:

•/sapdb/programs: this can be seen as a central directory with all MAXDB executables. The directory is shared between all MAXDB instances that reside on the same host. It is also possible to share the directory across hosts. But it is not possible to use different executable directories for two MAXDB instances on the same host. Furthermore, it might happen that different SAPDB versions get installed on the same host. The files in /sapdb/programs have to be of the newest version that any MAXDB on the cluster nodes has. Files in /sapdb/programs are downwards compatible. For liveCache 7.4 and APO 3.1 using SAPDB 7.3 this means that within /sapdb/programsthere have to be the SAPDB 7.4 version executables installed. It is important to realize, that also any SAPDB based SAP application server instance will use this path to access the database client files.

•/sapdb/data/config: This directory is also shared between instances, though you can find lots of files that are Instance specific in here, e.g. /sapdb/data/config/<DBSID>.* According to SAP this path setting is static.

•/sapdb/data/wrk: The working directory of the main MAXDB processes is also a subdirectory of the IndepData path for non-HA setups. If a SAPDB restarts after a crash, it copies important files from
