Overview

Package common provides general utilities.

Some utility function(s) for oracle connection strings.

Helpers for communicating with Database Daemon. Both *nix domain socket and TCP/IP communication with the Database Daemon are supported with domain sockets being the default mechanism.

Functions

func DatabaseDaemonDialLocalhost

func DatabaseDaemonDialLocalhost(ctx context.Context, port int, opts ...grpc.DialOption) (*grpc.ClientConn, error)

DatabaseDaemonDialLocalhost connects to a local Database Daemon via gRPC.

func DatabaseDaemonDialService

func DatabaseDaemonDialService(ctx context.Context, serviceAndPort string, opts ...grpc.DialOption) (*grpc.ClientConn, error)

DatabaseDaemonDialService connects to Database Service via gRPC.

func DatabaseDaemonDialSocket

func DatabaseDaemonDialSocket(ctx context.Context, socket string, opts ...grpc.DialOption) (*grpc.ClientConn, error)

DatabaseDaemonDialSocket connects to Database Daemon via gRPC.

func EZ

func EZ(user, pass, host, port, svc string, asSysDba bool) string

EZ returns EZConnect string compatible with oracle tooling. All parameters except host are optional, refer to documentation. See https://docs.oracle.com/database/121/NETAG/naming.htm#NETAG1112.
