This topic lists environment variables that relate to configuring the file and dataset handling.
Specifies the directory or directories that the run-time system is to search for data files. Provides you with the facility to map data files globally, thus enabling you to put working data files in a directory whose name is not known until run time.
Syntax
COBDATA=pathname[:pathname]... export COBDATA
Comments
COBDATA affects the compiler and other utilities. During compilation, for example, program source is regarded as a data file by the compiler. If you intend to use any COBOL development system utilities, we recommend that the COBDATA value starts with a colon (:).
COBDATA is considered set if there is an environment variable of this name in your environment space, and its value is non-empty.
The full mapping order for files is:
For multiple directory paths specified either in the COBDATA environment variable or a dd_ environment variable, the system searches the first directory specified followed by a slash (/) as a prefix to the user name.
If the filename is not found, or is not readable, the search continues with the next directory until the final directory has been searched. If no file is found, the first directory is used if a file is to be created.
Any dd_ and COBDATA mappings are ignored for any filename that starts with a hyphen () or a slash (/). In addition, it is illegal to have a hyphen in an environment variable name.
When using this facility, you should not use a filename that starts with "COB... "(these are reserved for the COBOL system).
You can use the COBDATA environment variable for files open in any mode (including OUTPUT) and for fixed or variable length files. If you are using indexed files, both the data and index files must be in the same directory.
The COBDATA environment variable affects file deletes, using the rules given here, as well as file opens.
If you intend to use COBOL development system programs, we recommend that you first unset COBDATA, as many of these programs open data files and are thus affected by the value of COBDATA. If you have to set COBDATA, you should include the paths :$COBDIR/dynload/helptbox.lbr and :$COBDIR/dynload/check.lbr at the beginning of the COBDATA value. If you want to see the Animator Help pages, also include COBDIR/dynload/advanim.lbr.
Example
COBDATA=:demo:/home/data:progs export COBDATA
causes COBDATA to be set to instruct the run-time system to search for data files in the current directory, then in the directory ./demo, then in the directory /home/data and finally in ./progs.
Values
Enables or disables database file handler support. This is required if your data files are stored in a datastore, or your enterprise server region stores some of its resources in a database; see Micro Focus Native Database File Handling and Enterprise Server Region Database Management for more information.
Syntax
ES_DB_FH=value export ES_DB_FH
Values
Default
Database file handler support is disabled.
Specify the name of the database server to be used for region database operations.
There also needs to be a corresponding <server> entry for the database server within the configuration file specified by the MFDBFH_CONFIG environment variable. <dsn> entries for the region, cross-region and master databases must also be specified in the configuration file to enable use of region database operations.
Syntax
ES_DB_SERVER=server-instance export ES_DB_SERVER
Values
server-instance is the name of a valid database server instance. For example, set ES_DB_SERVER=(local)\SQLEXPRESS.
Default
Not set.
Using the example above, you would be required to have something similar to that below in your database configuration file:
<?xml version="1.0" encoding="utf-8"?>
<datastores usevault="false">
<server name="(local)\SQLEXPRESS" type="sqlserver" access="odbc">
<dsn name="SS.MYMASTER" type="database" dbname="master"/>
<dsn name="SS.CAS.ESDEMO" type="region.cas" region="ESDEMO" feature="all"/>
<dsn name="SS.CAS.CROSSREGION" type="crossregion.cas"/>
</server>
</datastores>
Specifies the region database that is to process resource locking (step- and system-scoped ENQs) for an enterprise server within a cluster, where resources (such as spool queues and catalogs) are deployed to a database.
Syntax
ES_LOCKDB=region-db export ES_LOCKDB
Parameters
Syntax
ES_RLS_FILE_SUPPORT=value export ES_RLS_FILE_SUPPORT
Values
Default
RLS file support is off.
Syntax
EXTFH=filename.cfg export EXTFH
Parameters
filename.cfg The name of the configuration file.
Example
EXTFH=/home/mydir/myconfig.cfg export EXTFH
Syntax
FHREDIR=filename.cfg export FHREDIR
Parameters
filename.cfg The name of the configuration file.
Example
FHREDIR=/home/mydir/myconfig.cfg export FHREDIR
Specifies a configuration file to be used by the Fileshare Server.
Syntax
FS=filename.cfg export FS
Parameters
filename.cfg The name of the configuration file.
Example
FS=myconfig.cfg export FS
Syntax
FSCOMMS="\$local" export FSCOMMS
Parameters
"\$local" Run the Fileshare System in single user mode.
Syntax
Parameters
pathname The directory that the DB2 ECM is to use to store bind files.
Example
SET HCOBND=/mydir/binds export HCOBND
Comments
The DB2 ECM uses the specified directory until the variable is unset or reset to a different directory. The DB2 Compiler directive option BIND overrides this environment variable.
For EBCDIC datasets, translates from EBCDIC to ASCII using a PUT, and ASCII to EBCDIC using a GET.
Syntax
MFFTP_ASCII_CMD_XLATE={Y|N}
Comments
When set to Y, must be used with TYPE A or ASCII sub command.
MF_LEX_API={1|2|D}|1D|2D
MF_LEX_API=1
Specifies the location and the name of the configuration file that defines the database server instances and associated databases.
Syntax
MFDBFH_CONFIG=value export MFDBFH_CONFIG
Values
value represents the full path and filename of your database configuration file.
Default
Not set.
Specifies the type of record locking that it is to be used when the database file handler is in effect.
Syntax
MFDBFH_RECORD_LOCKING=table|database export MFDBFH_RECORD_LOCKING
Parameters
Default
Specifies the location of the scripts and stored procedures required when the database file handler is in effect.
Syntax
MFDBFH_SCRIPT_DIR=value export MFDBFH_SCRIPT_DIR
Values
value represents a path to the directory containing the required resources.
Default
value defaults to the \etc\mfdbfh\scripts sub directory of your product installation directory.

Syntax
MFDBFH_VAULT=value export MFDBFH_VAULT
Values
value represents the name of a vault.
Default
Not set.
Syntax:
strictvsam=ON|OFF
