This is a module which provides Oracle connectivity for OpenSER.
It implements the DB API defined in OpenSER.
Dependencies

The following modules must be loaded before this module:
No dependencies on other &ser; modules.
External Libraries or Applications
The following libraries or applications must be installed before running
&ser; with this module loaded:

Exported Parameters
timeout (fixedpoint)
Timeout value for any operation with BD.
Possible values is from 0.1 to 10.0 seconds.
Default value is 3.0 (3 second).
If value of timeout parameter set to 0, module use synchronous
mode (without timeout).
Set timeout parameter
...
modparam("db_oracle", "timeout", 1.5)
...
Disable asynchronous mode
...
modparam("db_oracle", "timeout", 0)
...
reconnect (fixedpoint)
Timeout value for connect (create session) operation.
Possible values is from 0.1 to 10.0 seconds.
Default value is 0.2 (200 milliseconds).
Set reconnect parameter

Installation
Because it dependes on an external library, the oracle module is not
compiled and installed by default. You can use one of the next options.
- edit the "Makefile" and remove "db_oracle" from "excluded_modules"
list. Then follow the standard procedure to install &ser;:
"make all; make install".
- from command line use: 'make all include_modules="db_oracle";
make install include_modules="db_oracle"'.
Utility openser_orasel
For working with openserctl script, should be able to print the 'query'
results to the terminal in a user-readable form. The standard command-line
Oracle client (sqlplus) is not quite suitable for this, as it cannot align
row width to real (received) data's (it always prints a cell width as
described in the db scheme). This problem has been solved by inclusion the
utility openser_orasel, which formats printing approximately in the same
way as the 'mysql' client utility. In addition, this utility known about
the "agreements and types" in DB that are used in OpenSER for the work
with Oracle and formats printing taking these into account.
