# LDM for AWIPS and GEMPAK
|
|
|
|
It is possible to have two LDM installs (since AWIPS LDM installs to `/awips2/ldm` and is owned and run by user **awips:awips**. But two LDM clients doubles your bandwidth and uncessary. This document explains how the LDM keeps its EDEX processing separate from other processing (GEMPAK decoders, TDS, etc.).
|
|
|
|
### /awips2/ldm/etc/ldmd.conf
|
|
|
|
The defailt AWIPS LDM config file executes a single **pqact** process with the **-e** flag (for EDEX). The **edexBridge** server name is defined (typically the local machine name):
|
|
|
|
EXEC "pqact -e /awips2/ldm/etc/pqact.conf"
|
|
EXEC "edexBridge -s $HOSTNAME"
|
|
|
|
A separate **EXEC** line should be added for GEMPAK decoders, *without* the **-e** flag:
|
|
|
|
EXEC "pqact -f IDS-DDPLUS /awips2/ldm/etc/pqact.gempak_decoders"
|
|
|
|
yum install apr-devel apr-util-devel "libdb-4.7.so()(64bit)"
