Overview This is a module which provides Oracle connectivity for OpenSER. It implements the DB API defined in OpenSER.
Dependencies
&ser; Modules 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: instantclient-sdk-10.2.0.3 - the development headers and libraries of OCI.
Exported Parameters
<varname>timeout</varname> (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 <varname>timeout</varname> parameter ... modparam("db_oracle", "timeout", 1.5) ... Disable asynchronous mode ... modparam("db_oracle", "timeout", 0) ...
<varname>reconnect</varname> (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 <varname>reconnect</varname> parameter ... modparam("db_oracle", "reconnect", 0.5) ...
Exported Functions No function exported to be used from configuration file.
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.
