An instance is defined by the parameters used to build it in memory Many, though not all parameters, can be changed after startup Some are fixed at startup time and can only be changed by shutting down the instance and starting again The parameters used to build the instance initially come either from the parameter file (which may be a static pfile or a dynamic spfile) or from defaults Every parameter has a default value, except for the DB_NAME parameter; this must always be specified In total there are close to three hundred parameters (the exact number will vary between releases and platforms) that it is acceptable for the DBA to set There are in fact about another fifteen hundred parameters, known as hidden parameters, that the DBA is not supposed to set; these are not usually visible and should only be set on the advice of Oracle Support The (approximately) three hundred parameters are divided into basic and advanced The idea is that most database instances will run well with default values for the advanced parameters Only about thirty-three (the exact number may vary between versions) are basic So setting parameters is not an enormous task But it is enormously important

open(DATA, "+>>filetxt");

The list of tricks for opening files does not end there Let s imagine a situation in which you need to read the contents of a compressed file within a script The normal method would be to use a function to call an external program that uncompresses the file so that you can read it, before recompressing the file once you finish But this is very time consuming, and on systems that have limited resources (CPU and disk space), it is extremely wasteful With Perl, you can open a filehandle that is associated with the output of an external command The gzcat function decompresses Gzipped files on the fly, sending the output to the commands stdout without actually decompressing the file to its full size You can use Perl to read in this information directly by using a pipe at the end of the EXPR:

free code 39 font for word, birt ean 128, word data matrix code, birt upc-a, free ean 13 barcode font word, barcode word 2007 freeware

To view the parameters and their current values, you may query the V$PARAMETER view:

open(GZDATA, "gzcat filegz|");

select name,value from v$parameter order by name;

You can now use one of the many functions that read from a filehandle to process the data being decompressed on the fly You haven t created a temporary file, nor will you have to recompress the data once you ve finished reading it The opposite is also true So you could, for example, send an email message by using the mail program and opening a filehandle to which you can write the email message:

open(EMAIL, "|mail mc@mcwordscom");

select name,value from v$spparameter order by name;

public short ToShort() { return((short) this); } public override string ToString() { return((string) this); } private short value; } The ToString() function is an override because it overrides the ToString() version in object.

The only limitation to this is that you cannot open an external program for both reading and writing; the pipes work only one way read when at the end, write when at the start You can also open STDIN and STDOUT directly by specifying and > , respectively The next forms allow you to duplicate a filehandle This is again similar to the shell tradition of being able to redirect information not to just one file, but to multiple files The duplication can be specified by the existing filehandle name:

The difference is the view from which the parameter names and values are taken V$PARAMETER shows the parameter values currently in effect in the running instance V$SPPARAMETER shows the values stored in the spfile on disk Usually, these will be the same But not always Some parameters can be changed while the instance is running; others, known as static parameters, are fixed at instance startup time A change made to the changeable parameters will have an immediate effect on your running instance and can optionally be written out to the spfile If this is done, then the change will be permanent: the next time the instance is stopped and started, the new value will be read from the spfile If the change is not saved to the spfile, then the change will only persist until the instance is stopped To change a static parameter, the change must be written to the spfile, but it will only come into effect at the next startup If the output of the two preceding queries differs, this will typically be because the DBA has done some tuning work but not yet made it permanent, or has found it necessary to adjust a static parameter and hasn t yet restarted the instance The other columns in V$PARAMETER and V$SPPARAMETER are self-explanatory They show information such as whether the parameter can be changed (for a session or for the whole instance), whether it has been changed, and whether it has been specified at all or is on default
