Chapter 4: Loading TAQ Data

Load process directories

You need to create certain directories for the load process on the UNIX machine where you installed the repository and cache databases.

The following is an example directory structure for the automated load process:

/work3/LoadProcess
    data
        ase_in
            active
            log
        iq_in
            active
            log
        archive
        rap_in
        .status
    iq_load_scripts

In this example, the values of the environment variables defined in the set_rap_env_pl.sh script are:

Variable name	Value
$RAP_HOME	/work3/LoadProcess
$RAP_DATA	/work3/LoadProcess/data/ase_in
$IQ_DIR	/work3/LoadProcess/data/iq_in
$RAP_ARCH	/work3/LoadProcess/data/archive
$RAP_IN	/work3/LoadProcess/data/rap_in
$RAP_STAT	/work3/LoadProcess/data/.status
$LOAD_IQ_SCRIPT_DIR	/work3/LoadProcess/iq_load_scripts

The two directories active and log must be created under both $RAP_DATA and $IQ_DIR.
