Need help with a sh script to spool directory and modify the output (Oracle cnt file)
Hi,
I'm creating a shell script to dynamically create a recreate controlfile for an Oracle database. I need to read a cold backup file system, and make some changes to these files.
Let's say for argument sake the directory name is /ebsprod_c/oradata and it looks like this:
/ebsprod_c/oradata/ctxd01.dbf
/ebsprod_c/oradata/discoverer01.dbf
/ebsprod_c/oradata/log01.dbf
/ebsprod_c/oradata/log02.dbf
/ebsprod_c/oradata/undo01.dbf
/ebsprod_c/oradata/undo02.dbf
/ebsprod_c/oradata/undo03.dbf
/ebsprod_c/oradata/undo04.dbf
/ebsprod_c/oradata/undo05.dbf
What I need is to:
a. exclude the log0* files
b. Add a apostrophe and a comma to each line, except the last line which should only have a apostrophe to make it look something like this:
'/ebsprod_c/oradata/ctxd01.dbf',
'/ebsprod_c/oradata/discoverer01.dbf',
'/ebsprod_c/oradata/undo01.dbf',
'/ebsprod_c/oradata/undo02.dbf',
'/ebsprod_c/oradata/undo03.dbf',
'/ebsprod_c/oradata/undo04.dbf',
'/ebsprod_c/oradata/undo05.dbf'
I figured out how to spool the files and add the apostrophe and comma:
for dirname in $(ls /ebsprod_c/oradata/*.dbf)
do
filename=$(echo $dirname)
echo "'$filename'," >> datafiles.tmp
done
But I can't figure out how to remove/exclude the comma from the last line and how to exclude the log0* files.
Any help would be appreciated!
Thanks!
Mark

LEARN ABOUT PHP
oci_set_module_name
OCI_SET_MODULE_NAME(3) OCI_SET_MODULE_NAME(3)
oci_set_module_name - Sets the module name
SYNOPSIS
bool oci_set_module_name (resource $connection, string $module_name)
DESCRIPTION
Sets the module name for Oracle tracing.
The module name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement
is executed.
The name can subsequently be queried from database administration views such as V$SESSION. It can be used for tracing and monitoring such
as with V$SQLAREA and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.
The value may be retained across persistent connections.
PARAMETERS
o $connection
-An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
o $module_name
- User chosen string up to 48 bytes long.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
NOTES
Note
Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards.
Tip
Performance
With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack-
age. This is less efficient than using oci_set_client_info(3).
Caution
Roundtrip Gotcha
Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is
enabled.
EXAMPLES
Example #1
Setting the module name
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the module
oci_set_module_name($c, 'Home Page');
// Code that causes a roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the
// modules in use:
sqlplus system/welcome
SQL> select module from v$session;
