If I understand, you want to create metacode that generates a .ctl on the fly. There have been discussions at various levels about this idea at www.orafaq.com
There are several examples - search for dynamic control file
To answer your question - you have to use a scripting facility (perl, ksh, etc.), I assume you are. Then you can use patternmatching or regex to find your database name.
A list of all the Oracle sids must live in the tnsnames.ora in the $ORACLE_HOME/network/admin tree. First, you have to parse that file for db names. You have to validate the names anyway, bad name=load failure. Then use the array of names to search for '@' prefixed on all of your possible dbnames.
Our tnanames files all have the sid on a single line by itself, so this works
Code:
#!/bin/ksh
let cnt=0
set -A sidlist
tr -s '[:upper:]' '[:lower:]' < $ORACLE_HOME/network/admin/tnsnames.ora |\
grep 'sid =' | awk '{print $3}' \
while read sid
do
sidlist[cnt]=$sid
let cnt=$cnt+1
done

oci_new_connect
OCI_NEW_CONNECT(3)OCI_NEW_CONNECT(3)oci_new_connect - Connect to the Oracle server using a unique connectionSYNOPSIS
resource oci_new_connect (string $username, string $password, [string $connection_string], [string $character_set], [int $ses-
sion_mode])
DESCRIPTION
Establishes a new connection to an Oracle server and logs on.
Unlike oci_connect(3) and oci_pconnect(3), oci_new_connect(3) does not cache connections and will always return a brand-new freshly opened
connection handle. This is useful if your application needs transactional isolation between two sets of queries.
PARAMETERS
o $username
- The Oracle user name.
o $password
- The password for $username.
o $connection_string
-Contains the Oracle instance to connect to. It can be an Easy Connect string, or a Connect Name from the tnsnames.ora file, or
the name of a local Oracle instance. If not specified, PHP uses environment variables such as TWO_TASK (on Linux) or LOCAL (on
Windows) and ORACLE_SID to determine the Oracle instance to connect to. To use the Easy Connect naming method, PHP must be linked
with Oracle 10 g or greater Client libraries. The Easy Connect string for Oracle 10 g is of the form: [//]host_name[:port][/ser-
vice_name]. From Oracle 11 g, the syntax is: [//]host_name[:port][/service_name][:server_type][/instance_name]. Service names can
be found by running the Oracle utility lsnrctl status on the database server machine. The tnsnames.ora file can be in the Oracle
Net search path, which includes $ORACLE_HOME/network/admin and /etc. Alternatively set TNS_ADMIN so that $TNS_ADMIN/tnsnames.ora
is read. Make sure the web daemon has read access to the file.
o $character_set
-Determines the character set used by the Oracle Client libraries. The character set does not need to match the character set used
by the database. If it doesn't match, Oracle will do its best to convert data to and from the database character set. Depending on
the character sets this may not give usable results. Conversion also adds some time overhead. If not specified, the Oracle Client
libraries determine a character set from the NLS_LANG environment variable. Passing this parameter can reduce the time taken to
connect.
o $session_mode
-This parameter is available since version PHP 5 (PECL OCI8 1.1) and accepts the following values: OCI_DEFAULT, OCI_SYSOPER and
OCI_SYSDBA. If either OCI_SYSOPER or OCI_SYSDBA were specified, this function will try to establish privileged connection using
external credentials. Privileged connections are disabled by default. To enable them you need to set oci8.privileged_connect to
On. PHP 5.3 (PECL OCI8 1.3.4) introduced the OCI_CRED_EXT mode value. This tells Oracle to use External or OS authentication,
which must be configured in the database. The OCI_CRED_EXT flag can only be used with username of "/" and a empty password.
oci8.privileged_connect may be On or Off. OCI_CRED_EXT may be combined with the OCI_SYSOPER or OCI_SYSDBA modes. OCI_CRED_EXT is
not supported on Windows for security reasons.
RETURN VALUES
Returns a connection identifier or FALSE on error.
EXAMPLES
The following demonstrates how you can separate connections.
Example #1
oci_new_connect(3) example
<?php
// create table mytab (mycol number);
function query($name, $c)
{
echo "Querying $name
";
$s = oci_parse($c, "select * from mytab");
oci_execute($s, OCI_NO_AUTO_COMMIT);
$row = oci_fetch_array($s, OCI_ASSOC);
if (!$row) {
echo "No rows
";
} else {
do {
foreach ($row as $item)
echo $item . " ";
echo "
";
} while (($row = oci_fetch_array($s, OCI_ASSOC)) != false);
}
}
$c1 = oci_connect("hr", "welcome", "localhost/orcl");
$c2 = oci_new_connect("hr", "welcome", "localhost/orcl");
$s = oci_parse($c1, "insert into mytab values(1234)");
oci_execute($s, OCI_NO_AUTO_COMMIT);
query("basic connection", $c1);
query("new connection", $c2);
oci_commit($c1);
query("new connection after commit", $c2);
// Output is:
// Querying basic connection
// 1234
// Querying new connection
// No rows
// Querying new connection after commit
// 1234
?>
