This chapter details how you can start and configure
ESCWA, including enabling it to operate using Transport Layer Security (TLS).
Note:
Enterprise Server Security is enabled by default. See
Default Enterprise Server Security Configuration for more information.
On UNIX, to start
ESCWA as default:
- From a command prompt, execute
cobsetenv to set the environment:
. <product-install-dir>/bin/cobsetenv
Note: The product install directory is typically located at
/opt/microfocus/VisualCOBOL/bin.
- Change to a new directory to store the
ESCWA standard output, in this case, in a file called
escwa.out and avoid blocking unmounting the current file system:
cd working-directory
- To execute
ESCWA in the background, type:
nohup escwa < /dev/null > escwa.out 2>&1 & disown
In addition,
ESCWA can only initially be contacted using the loopback address (localhost 127.0.0.1). You can access the application by using
the following URL in your Web browser:
http://localhost:10086.
Note: On the first occasion you access the Web interface, the following warning message is displayed:
- The ESCWA server is not TLS-enabled. Communications across the network will not be encrypted. Micro Focus recommends that
you enable TLS settings as soon as possible.
To restrict access to
ESCWA you need to enable a security manager. See
Specifying an External Security Manager for more information.
You can access
ESCWA from a Web browser on a remote host by turning off the loopback mode.
Note: Micro Focus recommends that you restrict access and enable TLS before turning off loopback mode.
You can turn off loopback mode using one of the following three methods:
- Modify the
ESCWA application configuration file:
- Edit the
commonwebadmin.json file, and change the value of the
MfRequestedEndpoint property to
tcp:*:10086.
The application configuration file is located in
$COBDIR/etc.
Note: The
commonwebadmin.json file is not overwritten when installing a new version of
Visual COBOL. Previous versions of
ESCWA used port 10004, therefore, you might need to modify the configuration file.
- Add a parameter to the service before starting it.
On UNIX:
- From a command prompt, execute
cobsetenv to set the environment:
. <product-install-dir>/cobsetenv
Note: The product install directory is typically located at
/opt/microfocus/VisualCOBOL/bin.
- Change directory to
$COBDIR/bin and type:
nohup escwa --BasicConfig.MfRequestedEndpoint="tcp:*:10086" --write=true < /dev/null > escwa.out 2>&1 &
- Modify the requested endpoint from within
ESCWA:
- In a browser, type the following into the search bar
localhost:10086.
- Click
.
This opens the
Enterprise Server Administration Configuration dialog box.
- Click
Server Settings to expand the available configuration options.
- In the
Hostname or IP Address field, type
*
- In the
Port field, type
10086
Note: You must restart the
ESCWA service if you modify these fields.
- Click
Apply.
Note: You can substitute the IP and port values of
tcp:*:10086 (protocol:ip_or_domain:port) with the IP or domain and port you require. The
--write=true parameter enables configuration changes to be written to the config file.
