NOTE For liveCache starting with version 7.6 these limitations do not exist any
more. The working directory is utilized by all instances (IndepData/wrk)
and can be globally shared.
/var/spool/sql: This directory hosts local runtime data of all locally
running liveCache/MaxDB Instances. Most of the data in this directory
becomes meaningless in the context of a different host after failover. The
only critical portion that still has to be accessible after failover is the
initialization data in /var/spool/sql/ini. This directory is almost
always very small (< 1MB).
