To Start ESCWA

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/opt/microfocus/EnterpriseServer/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:
1. 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:
1. 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.
2. 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:
1. In a browser, type the following into the search bar localhost:10086.
2. Click .
  This opens the Enterprise Server Administration Configuration dialog box.
3. Click Server Settings to expand the available configuration options.
4. In the Hostname or IP Address field, type *
5. In the Port field, type 10086
  Note: You must restart the ESCWA service if you modify these fields.
6. 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.
