MAXQUERYLEN : Identifies the length of the longest query (in seconds) executed in the instance during the period.
You can use this statistic to estimate the proper setting of the UNDO_RETENTION initialization parameter.
The length of a query is measured from the cursor open time to the last fetch/execute time of the cursor.
Only the length of those cursors that have been fetched/executed during the period are reflected in the view.
Query which orders the MAXQUERYLEN column of v$undostat data in descending order .
select *
from v$undostat us , v$sql s
where us.MAXQUERYID = s.sql_id
order by UNDOBLKS desc;
We can use maxqueryid column present in v$undostat to join with v$sql view in order to get sql query which is using undo space.
How do you get the undo usage ?
UNDOBLKS column present in the v$undostat gives the number of undo blocks are being used currently. you have to multiply with size of block to get the usage.
how total undo size is calculated.
Content column present in dba_tablespaces provides information regarding whether tablespace is a temporary tablespace , permanent tablespace or undo tablespaces.
there you can retrive all undo tablespaces. sometimes tablespace may be offline . so filter only online undo tablespace using status column of dba_tablespaces
now I need all the datafiles associated to these undo tablespaces to get bytes or size of datafiles. this we can get from v$datafile but concern is v$datafile doesn't contain
any undotablespace name or any tablespace name . it contain tablespace number hence I need to combine tablespace_name of dba_tablespaces to name column of v$tablespace
which contain tablespace name with it id. so here I am getting id of tablespace with I need to combine with v$datafile to get total bytes used for undo tablespace.
SQL> select sum(d.bytes) "undo"
2 from v$datafile d,
3 v$tablespace t,
4 dba_tablespaces s
5 where s.contents = 'UNDO'
6 and s.status = 'ONLINE'
7 and t.name = s.tablespace_name
8 and d.ts# = t.ts#;

HOw do you check whether FTP is configured and running or not ?
I found that I have several services running related to ftp
cat /etc/services | grep ftp
ftp-data 20/tcp
ftp 21/tcp
tftp 69/udp
sftp 115/tcp
ftps-data 989/tcp # FTP over SSL (data)
ftps 990/tcp
venus-se 2431/udp # udp sftp side effect
codasrv-se 2433/udp # udp sftp side effect
frox 2121/tcp # frox: caching ftp proxy
zope-ftp 8021/tcp # zope management by ftp
The /etc/services file is used to tell what ports are standard for a given service. It does not mean that they are installed. If you look at the file, you can see that ftp data is transferred on port 21 using TCP and that port 21 is the standard ftp port and also uses TCP. It is a tool that client and servers can use to determine what ports to open for a connection. It is also a reference for administration purposes to know what service goes w/ what ports.

Peoplesoft
Components of a PeopleSoft System
PeopleSoft is a chain of linked technologies that stretch between the user and the database.
The database is fundamental to the entire structure, but the technology stack stretches out through the BEA Tuxedo Application Server and the Java servlet to the user's browser
How do you memorise Peoplesoft Diagram ?
1) Peoplesoft schema it contains peoplesoft tables and application tables
of course who will monitor application tables.
Peoplesoft tools Application server
there will be webserver it is java enabled web browser between the Internet browser and Peoplesoft tool application
How people soft applications connect webserver . it is through Jolt and how webserver will connect to internet browser it is through HTTP.
what ever I have explained above is Application execution part .
There are actually 2 parts
1) application Execution part.
2) application Development part.
Application development part also contains people soft application server that server host application development tools. it is through Tuxedo
