Readers are kindly requested to share the different ways to achieve this task if they know!

select  s.sid sid,
s.serial# sh,
s.process pid,
decode (s.status, ‘INACTIVE’, ‘N’, ‘Y’) ia,
decode (sw.wait_time, 0, ‘Y’, ‘N’) iw,
decode (sw.wait_time, 0, sw.seconds_in_wait, sw.seconds_in_wait-sw.wait_time/100) secs,
sw.event event,
decode (sq.sql_text, null, ‘ – Not Available -’, sq.sql_text) sql
from    v$session_wait sw,
v$session s,
v$sql sq
where   s.sid = sw.sid and
s.sql_hash_value = sq.hash_value(+) and
s.program like ‘%&program%’
and upper(sq.sql_text) not like ‘%CONFIGURATION%’;

And to kill a particular session, use following query:

alter system kill session ‘<Serial#>,<PID>’;

Hope this helps.

psrinfo – displays information about processors.
prtconf - print system configuration.
dmesg - collect system diagnostic messages to form error log.

Ex:

(My machine is having 4 physical processors which are divided into 8 Virtual processors)

$> psrinfo -p
4

$> psrinfo -pv
The UltraSPARC-IV physical processor has 2 virtual processors (0, 16)
The UltraSPARC-IV physical processor has 2 virtual processors (1, 17)
The UltraSPARC-IV physical processor has 2 virtual processors (2, 18)
The UltraSPARC-IV physical processor has 2 virtual processors (3, 19)

Refer the man pages for more information on the above commands.

Usually, when we make some script file to Clearcase elements, its permission will still be maintained. But when we check-in the same file, it’ll be having Read-Only permissions.

So, how to retain the permissions of a file after check in also? Use ‘protect’ option.

ct protect -r -chmod 555 <directory-or-file-name>

Note:  ‘-r’ option is valid only for Directories.

What does it do exactly? A lot:

* Set a parameter as an integer by using -i option so as to fasten the arithmetic operations on that variable.

* Convert to lower case using -l

* Mark a variable as Read-only using -r

etc…

Converting into upper case? Yes, you guessed it right, use -u option.

How to use it? You can use it before assignment or after assignment, does not make much difference.

Whats more? You can even give more that one variable to this typeset command.

For more information on typeset, use man typeset.

Well, renaming a Clearcase View requires the renaming of both the storage and the tag. Here are the basic steps for the same but you are recomended to refer the Product Documentation if it doesn’t work:

1. Stop the view
PROMPT> cleartool endview <view-tag>

2. Remove the view tag to untag the view
PROMPT> cleartool rmtag -view <view-tag>

3. Remove the Clearcase registry entry to unregister the view object
PROMPT> cleartool unregister -view <vie-storage-path-name>.vps

4. Rename the view storage directory
PROMPT> mv <old-view-storage>.vps <new-view-storage>.vps

5. Register the new name fo the view storage
PROMPT> cleartool register -view <new-view-storage-path-name>.vps

6. Create a new tag for the view
PROMPT> cleartool mktag -view -tag <new-view-tag> <new-view-storage-path-name>.vps

As it is on Solaris machine, no need to start the view explicitly. You can directly start working by setting the new view.

Note: These steps are just for rename operation. If you wish to move, not rename, the snapshot view directory which contains special files, you need to take some additional steps.

Then the prompt changes and you can install the DBI using the following command:

Install DBI

In the same way, you can install other packages also.

But If one needs more granular output, say in HH:MM:SS format, here is a way out, use “echo %TIME%” which expands to current time using same format as TIME command.

There are so many other things which can be echoed. For example, try any of the following variables:

%CD% – expands to the current directory string.

%DATE% – expands to current date using same format as DATE command.

%RANDOM% – expands to a random decimal number between 0 and 32767.

%ERRORLEVEL% – expands to the current ERRORLEVEL value

%CMDEXTVERSION% – expands to the current Command Processor Extensions version number.

%CMDCMDLINE% – expands to the original command line that invoked the Command Processor.

%PATH% – expands the current PATH variable.

etc….

Following code snippet can give you can idea how an expect script may look like. The “cmdFile” may contain some commands to achieve some functionality like changing the current directory and putting some files in it.

#!/usr/local/bin/expect

spawn  sftp -b cmdFile ganga_k@172.16.2.21

expect “password:”

send “password\n”;

interact

#!/usr/local/bin/sh –x

This is going to print the steps the compiler goes through.
