Run a Test Program to Verify Replication

Once you have verified that the high availability group is configured correctly, run the following COBOL program to demonstrate that the replication process is working correctly within the group. This program creates a data file, the name of which was added to the dbase.ref file in an earlier step. When the program has finished, the data file (file.dat) should have been created on the primary server (RED), then replicated to the standby servers (GREEN and BLUE).

In a separate directory to any of the system directories (for example, c:\HA on Windows platforms), create a new file called runner.cbl, then paste the following code into it and save the file:

      $set callfh"FHREDIR"
       environment division.
       configuration section.
       input-output section.
       file-control.

           select optional idxfile
               assign to disk "file.dat"
               organization is indexed
               access is dynamic
               lock mode is automatic
               record key is idxfile-primary-key
               file status is file-status.

       data division.
       file section.

       fd  idxfile.
       01  idxfile-rec.
           03  idxfile-primary-key pic 999999999.
       
       working-storage section.
           01 file-status.
                05 status-key-1     pic x.
                05 status-key-2     pic x.
                05 binary-status redefines status-key-2  pic 99 comp-x.
           
       Procedure Division.
           open output idxfile
           move 0 to idxfile-primary-key
           perform 100 times
              perform 20 times
              add 1 to idxfile-primary-key
                  write idxfile-rec
              end-perform
              commit
           end-perform
           close idxfile
           stop run.

From an Enterprise Developer command or shell prompt, type:
Windows:
```
cobol runner.cbl int();
```
UNIX:
```
cob runner.cbl;
```
The COBOL file is compiled to an .int file.
In the same directory, create the fhredir.cfg file that is specified in the COBOL program, then paste the following options into it and save the file.
```
/s FS1
/um
/ra 5
/rd 5000
/cm ccitcp
```
See Fileshare Client Configuration Options for details on each option.
Run the program by typing the following:
Windows:
```
run runner.int
```
UNIX:
```
cobrun runner.int
```
Tip: While the program is running, on the Enterprise Server Administration home page, for the primary server, click Details > ES Monitor & Control > iFSView > files get to show the open file within Fileshare.
When the program has completed, check the system directory for each server: they should each contain file.dat. This verifies that replication is working correctly within the group.
