How to define "Remote process" for Tomcat connection in Firebird

I am writing a web service project with Eclipse, connecting to Firebird database using Tomcat 8 server. Problem is in IBExpert tool, connections from Tomcat show null value in "Remote Process" column, so I don't know which connection comes from Tomcat.

Is there anyway to naming the connections of Tomcat in there? Maybe show path of Tomcat exe file or simply give it a text?

Here the code I use to create connection with HirakiCP library.

public class DBConnection {
    private static final int READ_ONLY = 0;
    private static final int READ_WRITE = 1;
    private static final int CREATE_NEW = 2;

    private static HikariConfig config;
    private static HikariDataSource datasource;

    public static DataSource getDataSource(String dbIP, String dbName,
            String dbUsername, String dbPassword) {
        if (datasource == null) {
            config = new HikariConfig();

            config.setDriverClassName(Constants.DB_DRIVER);
            config.setJdbcUrl(Constants.DB_URL + dbIP + "/" + dbName
                    + "?dialect=3&lc_ctype=UNICODE_FSS");
            config.setUsername(dbUsername);
            config.setPassword(Utility.dbDecrypt(dbPassword));

            config.addDataSourceProperty("cachePrepStmts", "true");
            config.addDataSourceProperty("prepStmtCacheSize", "250");
            config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
            config.setMaximumPoolSize(5);
            config.setMinimumIdle(2);
            config.setConnectionTimeout(TimeUnit.SECONDS.toMillis(30));
            config.setLeakDetectionThreshold(TimeUnit.SECONDS.toMillis(10));

            datasource = new HikariDataSource(config);
        }
        return datasource;
    }

    /*
     * Method to create DB connection
     * 
     * @param dbIP
     * 
     * @param dbName
     * 
     * @param dbUsername
     * 
     * @param dbPassword
     * 
     * @return connection
     */

    @SuppressWarnings("finally")
    public static Connection createConnection(String dbIP, String dbName,
            String dbUsername, String dbPassword, int conType) {
        Connection con = null;

        if (datasource == null) {

            // Create new datasource
            datasource = (HikariDataSource) getDataSource(dbIP, dbName,
                    dbUsername, dbPassword);
        }

        try {

            // Use existing datasource
            con = datasource.getConnection();

            if (conType == READ_ONLY) {
                con.setReadOnly(true);
            } else {
                con.setReadOnly(false);
            }
        } finally {
            return con;
        }
    }
}

This is not specific to IB Expert (which is also why I removed that tag from your question). This is information reported by the MON$ATTACHMENTS table of Firebird.

When using Jaybird (the Firebird JDBC driver) you have a number of options to set the process name:

1. Set system property org.firebirdsql.jdbc.processName. For example, by:
   • Setting -Dorg.firebirdsql.jdbc.processName=Tomcat in the startup script of Tomcat
   • Using System.setProperty("org.firebirdsql.jdbc.processName", "Tomcat") before initializing the connection pool.
2. Specify connection property processName. For example, by:
   • Adding processName=Tomcat in the JDBC URL
   • Specifically for HikariCP, configuring it with config.addDataSourceProperty("processName", "Tomcat")

See also Process information in the Jaybird JDBC Driver Java Programmer's Manual.

Disclosure: I maintain the Jaybird driver, and wrote parts of the documentation I linked.
