A. NETWORK INFORMATION
----------------------
Informix JDBC Driver supports only the TCP/IP protocol, which means
you can connect to SE database servers only through the "setlitcp" or
"sesoctcp" network protocols. Some platforms, such as Solaris, only
support "setlitcp"; other platforms only support "sesoctcp." Check
your SE database server machine notes to verify the network protocol
supported by your platform.
To use the TCP/IP protocol, you must bring up an SE daemon. First
define an SE database server name in the SQLHOSTS file, specifying
either "setlitcp" or "sesoctcp," as shown in the following example:
myserver_tli setlitcp myhost sqlexec
Assume that in the example, "sqlexec" has a port number of 1525. This
information will be used in a later example.
To bring up the SE tlitcp daemon, execute the following command as
the "root" user:
$INFORMIXDIR/lib/sqlexecd myserver_tli -l /tmp/selog_tli
Use the UNIX "ps" command to check whether the SE daemon has been
successfully started.
B. DATABASE DIRECTORIES
-----------------------
INFORMIX-SE database servers can only read from or write to the
local directories on the computer where the SE daemon was started.
This means, for example, that you cannot create a database on an
NFS-mounted directory on the computer where the SE daemon was started.
By default, when you create a database through Informix JDBC Driver,
the driver asks the SE database server to create the database in your
home directory. This means that your home directory cannot be an NFS-
mounted directory.
If you do not want the database to be created in your home directory,
you can specify another directory by using the following syntax
after connecting to the SE database server:
CREATE DATABASE '//server-name/path/database_name';
For example, the following statement creates the database called
MYDB in the directory "/tmp/mydb.dbs" using the SE database server
"myserver_tli":
CREATE DATABASE '//myserver_tli/tmp/mydb';
You can specify this database in a database URL in your Java program,
as shown in the following example:
url = "jdbc:informix-
sqli://myhost:1525//tmp/mydb:informixserver=myserver_tli;user=rdtest;passw ord=test";
