How to Install rpm package on linux

rpm -ivh <package_name.rpm> // extension rpm is required at the last of package name

How to uninstall rpm packge on linux

rpm -ev <package_name> // no rpm extension is required at the last of package name

Update statement taking time to complete

Scenario :-- I executed update statement and it ran giving 1 row updated . Then putty session timed out

I reconnected to putty session and executed the select query to check whether rows has been updated or not .

It showed me rows not updated

I was worried as if happened

I reran the update query to update the rows then it hang for long time

I did following analysis

1) Checked the filesystem usage :-- Its was ok
2) Check the tablespace usage :-- It was ok
3) Check the oracle alert log it was ok
4) Then i checked the locks in the database and i found that there is lock in the table which needs to be updated
5) I killed the Inactive session to release the lock

The update query which was hung completed by saying 0 rows updated

I ran again the select query and this time i can see the values are updated

Friday, October 3, 2014

Select statement modifies blocks in two situations: first when the option for update is specified,and second when deferred block cleanout occurs

to store fewer rows per block ,either a higher pctfree or a smaller block size can be used

the goal of freelist is to spread concurrent insert statements over several blocks

To have data compression at the table level . Following condition must be full fulled

1) The table cannot have more than 255 columns
2) The table cannot be created with parameter rowdependencies

Free space in the compressed block caused by delete statements is never used

Data compression should be used for read-only table

Data Marts and Completely refreshed materialzed views are good candidate for data compression

Upgrading Oracle database 11.2.0.2 to 11.2.0.4

1) Patch Set to 11.2.0.3 has been suspended by oracle it means we need to go to 11.2.0.4

Step 1) Download and Install the 11.2.0.4 software binaries
Step 2) Run the pre-upgarde tool . From the existing oracle instance
$ORACLE_HOME/rdbms/admin/utlu112i.sql

If pre-upgrade tool is not run then error is obtained at the time of upgrade

Step 3) Run dbupgdiag.sql script from the below My Oracle Support article to verify that all the components in dba_registry are valid and no invalid data dictionary objects exist in dba_objects

Metalink id :-- Note 556610.1 ( For downloading the script for step 3)

Step 4)

If the dbupgdiag.sql script reports any invalid objects, run $ORACLE_HOME/rdbms/admin/utlrp.sql (multiple times) to validate the invalid objects in the database, until there is no change in the number of invalid objects.

Step 5) After validating the invalid objects, re-run dbupgdiag.sql in the database once again and make sure that everything is fine.

Step 6) Take the backup of the database before upgrade

rman target /
run
{
backup database plus archivelog ;
}

Step 7) Shutdown the database

Step 8) Copy the pfile,passwordfile to new dbs directory from old dbs directory

Step 9) Copy the listener.ora,tnsnames.ora and sqlnet.ora from old $ORACLE_HOME/network/admin to new $ORACLE_HOME/network/admin

Step 10) Set ORACLE_HOME to new binary location

Step 11) sqlplus / as sysdba
sql > startup upgrade
sql > @$ORACLE_HOME/rdbms/admin/catupgrd.sql;
sql > shutdown immediate
Step 12) Restart the database in normal mode

Step 13) @$ORACLE_HOME/rdbms/admin/catuppst.sql

Step 14) @$ORACLE_HOME/rdbms/admin/utlrp.sql;

Step 15) Run Script from step 3

Step 16) Upgrade the time zone to latest version using DBMS_DST

Parallel Processing

Parallel Processing should be used under this two conditions

1) When plenty of free resource is available . The aim of PX is to reduce the respnose time by distributing the work done by single process

2) It can used for SQL statements that take more than a dozen seconds to execute serially

If PX is commonly used for many SQL statements,the degree of parallelism should be set at the table or index level.

If it is used only for specific batches or reports . It is better to enable it at the session level or through hints

Insert statements with values clause cannot be parallelized

DML --> Insert,update,delete & merge can be executed in parallel when

1) Table has a trigger
2) A table has either a foreign key constraint refering itself
3) an object column is modified
4) a clustered or temporary table is modified

An actual distribution for a SQL statement , you can use the dynamic performance view v$pq_tqstat.

Information provided for current session and last SQL statements

Direct path insert gives better performance as it generates minimum undo . In fact undo is generated for only space management operation . For Ex :-- To increase the high watermark and to add new extent to the segment and not for the rows contained in the blocks that are inserted by direct-path .

The purpose of minimal logging is t
\'o minimize the redo generation

You can set minimual logging by setting parameter nologging at the table or partition level

Mimimial loggging is supported for direct path loads and some DDL Statements

Fetching numerous row at a time is called row prefetching

Row prefetching is enabled by JDBC drive by default

STATSPACK REPORT - P2

Load Profile Section

This is used for comparing two reports to see if the Load characteristics from the two report periods are similar

Sample Load Profile Section Report

Definition

a) Redo Size :-- Amount of Redo generated . If increase in the value more DML happening (INSERT,UPDATE & DELETE) than before

b) Logical Reads :-- Reading from memory and diskc
c) Block changes :-- The number of blocks modified during sample interval . If it is more ,more DML statements are taking place (INSERT,UPDATE & DELETE)
d) Physical Reads :-- The number of call that caused physical I/O
e) Physical Writes :-- The number of physical writes issued
f) User calls :-- The number of queries generated
g) Parses :-- Total of both parse hard and soft
h) Hard Parse :-- This is condition when sql statements is parsed .If it is 100% .This is bad .A hard parse is usually accompained by latch contention on the shared pool and library cache latches.
I) soft parse :-- This is obtained by subtracting hard parses from parse
j) Executes :-- How many statements we are executing per second/transaction
k) Transaction :-- How many transactions per second we process

Buffer Nowait Ration :-- This is the percentage of time that the instance made a call to get a buffer . Buffer was made available immediately meaning it did not had to wait for buffer.

Buffer Hit Ratio :-- Also know as buffer-cache hit ratio . It shows % of time a particular block was found in buffer cache instead of performing a physical I/O

Library Hit Ratio :-- give the percentage of pin requests that result in pin hits.A pin hit occurs when the sql or pl/sql code to be executed is already in the library cache and is valid to execute .If “Library Hit ratio” is low . It could mean low shared pool

Execute to Parse.:-- If value is negative, it means that the number of parses is larger than the number of executions. Another cause for a negative execute to parse ratio is if the shared pool is too small and queries are aging out of the shared pool and need to be reparsed.

Parse CPU to Parse Elapsd % :-- Generally this is measure of how available CPU cycles were for SQL parsing. If this is low you may see “latch free” as one of your top wait events.

Redo Nowait Ratio :-- This indicates the amount of redo entries generated for which there was space available in the redo log.

In Memory Sort Ratio :-- This give percentage sorts that were performed in memory.

Soft Parse Ratio :-- This ratio gives the % of parses that were soft,as opposed to hard.

Latch Hit Ratio :-- This is the ratio of total number of latch misses to the number of latch gets for all latches.
