Database File Handling Environment Variables

Lists environment variables related to the configuration of the database file handler, which enables you to store your data files for Enterprise Server applications within a supported database.
Parent topic: Environment Variables by Groups

ES_DB_FH

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 Database File Handler and Enterprise Server Region Database Management for more information.
Syntax 
ES_DB_FH={[Y|true]|[N|false]}
Parameters
Y|true
Use the Micro Focus Database File Handler (MFDBFH) to direct file handling.
N|false
Disable database file handling.
Default 
ES_DB_FH=N
Comments
Micro Focus recommends that you use the Advanced Region Properties page in the Enterprise Server Common Web Administration (ESCWA) interface to configure this environment variable. See Advanced Region Properties for more information.

ES_DB_SERVER

Specify the name of the database server to be used for region database operations.
Important: The configuration file specified by the MFDBFH_CONFIG environment variable must contain a corresponding <server> entry for the database server. <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
Parameter
server-instance
The name of a valid database server instance.
Default
Not set.
Comments
Micro Focus recommends that you use the Advanced Region Properties page in the Enterprise Server Common Web Administration (ESCWA) interface to configure this environment variable. See Advanced Region Properties for more information.
Example 
ES_DB_SERVER=MYSERVER

In this example, your database configuration file would need to contain something similar to the following: 

<datastores usevault="false">
   <server name="MYSERVER" 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>

ES_LOCKDB

Specifies the region database that is to process resource locking (step- and system-scoped ENQs) for an enterprise server region within a cluster, where resources such as catalogs are deployed to a database.
Syntax 
ES_LOCKDB=region-db
Parameter
region-db
The name of the region database responsible for processing step- and system-scoped ENQs.
Default
Not set.
Comments
This variable must be used in conjunction with ES_SERVER, in which ES_SERVER is set to the database server that houses the region database; see Resource Locking for more information.

MFDBFH_CONFIG

Specifies the location and the name of the configuration file that defines the database server instances and associated databases.
Syntax 
Windows:
MFDBFH_CONFIG=path-name\file-name
UNIX:
MFDBFH_CONFIG=path-name/file-name
Parameters
path-name
The full path to the location of the configuration file.
file-name
The file name of the configuration file.
Default
Not set. Uses the mfdbfh.cfg file found in the current working directory.
Comments
You can also set MFDBFH_CONFIG as a system environment variable.

MFDBFH_GRANT_USER_PERMISSIONS

Grants execute privileges to specific users or roles, for types and procedures that are created when configuring an Oracle database for MFDBFH access.
Syntax 
MFDBFH_GRANT_USER_PERMISSIONS={user|role}[{user|role}[...]]
Parameters
user
A user granted execute privileges for types and procedures created by MFDBFH.
role
A role granted execute privileges for types and procedures created by MFDBFH.
Default
Not set. Oracle default permissions are applied, which are to grant execute permissions to the schema owner of that type/procedure only.
Comments
This variable has no effect on permissions for any other database provider used with MFDBFH.

MFDBFH_RECORD_LOCKING

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}
Parameters
table
A file's record locks are held in a seperate lock table. (When using this locking mode, the behavior of record locking COBOL file operations closely follows the same behavior when using Fileshare.)
database
The native record locking mechanism of the database engine is used to establish and test locks on the data file records. This method improves performance, but at the cost of the locking behavior not exactly matching that of traditional COBOL record locking; see Record Locking Strategies for more information.
Default 
MFDBFH_RECORD_LOCKING=table

MFDBFH_SCRIPT_DIR

Specifies the location of the scripts and stored procedures required when the database file handler is in effect.
Syntax 
MFDBFH_SCRIPT_DIR=path-name
Parameter
path-name
The full path to the directory containing the required resources.
Defaults 
Windows:
MFDBFH_SCRIPT_DIR=%ProgramFiles(x86)%\Micro Focus\Enterprise Developer\etc\mfdbfh\scripts
UNIX:
MFDBFH_SCRIPT_DIR=$COBDIR/etc/mfdbfh/scripts

MFDBFH_VAULT

Specifies the name of a secrets vault.
Syntax 
MFDBFH_VAULT=vault-name
Parameter
vault-name
The name of a vault that is defined in the product's secrets.cfg file.
Default
Not set. Uses the default vault as defined in secrets.cfg.
Comments
For more information on secrets vaults, see Vault Facility.
