Oracle parameters tips

Oracle Database Tips by Donald BurlesonFebruary 10, 2015

I understand that Oracle is governed by parameters, but I need to know the location of the Oracle parameters and the details on the parameters that determine the configuration of Oracle.


Answer:  There are hundreds of Oracle parameters that govern the Oracle instance, and data dictionary, Oracle objects (table and index parameters) storage parameters and parameter for the listener the SQL*Net files.

Oracle*Net connections between servers can be tuned using several parameters. Keep in mind, though, that network tuning is outside the scope of Oracle, and a qualified network administrator should be consulted for tuning the network. The frequency and size of packet shipping across the network can be affected by using settings contained in the following parameter files:

  • protocol.ora file—tcp.nodelay
  • sqlnet.ora server file—automatic_ipc
  • sqlnet.ora client file—break_poll_skip
  • tnsnames.ora file—SDU, TDU
  • listener.ora file—SDU, TDU, and queuesize


Oracle initialization parameter file

When the Oracle database is started, one of the first things it needs to do is read the database initialization parameter file. The parameter file (init.ora or spfile) is created by the DBA and defines the overall instance configuration, such as how much memory should be allocated to the instance, the file locations, and internal optimization parameters.

OS parameters for Oracle

There are many OS kernel parameter that are set for the OS environment for Oracle.

Oracle network parameters


There are dozens of SQL*Net parameters that manage the communications between Oracle and the external environment (disks, network, TCP/IP, &c).  Also see the listener.ora parameters for managing connections to Oracle.
