VMware webconsole is not starting

vmware remote console
troubleshooting
issue: ipaddress/localhost:port/64 0r 48 or16 etc and not able to start the console
symptoms: this error comes when already console is open
this erros comes when ip address is not set
this error is related to dns server address also
solutions: use proper ip address related to subnet
give proper dns address and gateway
if u r on a standlone pc and wanna start console
then setup loop back adapter and set it a proper ip address gateway and dns address can be same as ip address
do ipconfig/ifconfig
thats it vmware webconsole will work without any issue this is related to IP or DNS only

Encryption example for solaris Servers

Logic used to safe transfer of files to storageserver1 for D92
Step 1
$ cat key.kxt
owtytninDgnikcufrofyekterceSasitI
Step 2
echo aravind11dec | encrypt -a arcfour -k key.kxt > datas.txt
Step 3
ftp -inv 3.58.48.105 << !
user storageserver1/myid `cat datas.txt | decrypt -a arcfour -k key.kxt`
ls
!
Step 4
cat ftptest.sh | encrypt -a arcfour -k key.kxt > data.txt

So we have two encrypted files
data.txt
datas.txt
key.kxt

How the script will run
cat data.txt | decrypt -a arcfour -k key.kxt|sh


It is a Secret Key
yekterceSasitI
for fucking D ninty two
owtytninDgnikcufrof
total key is
owtytninDgnikcufrofyekterceSasitI

rename all the files
as echo datas.txt | encrypt -a arcfour -k key.kxt > file1.fxt - filename for datas.txt
echo data.txt | encrypt -a arcfour -k key.kxt > file2.fxt - filename for data.txt
echo key.txt | encrypt -a arcfour -k key.kxt > file3.txt - filename for key.txt
refer file* in the script which use using decrypt

Final Logic

Step1:  Create encrypted username and password using key file
echo IT_FTP_BU | encrypt -a arcfour -k key.kxt > Data.un
echo Ptc784ccl | encrypt -a arcfour -k key.kxt > Data.p
echo Data.un | encrypt -a arcfour -k key.kxt > Un.Data
echo Data.p | encrypt -a arcfour -k key.kxt > p.Data
Step2: Create actual script
cd /dbf2/disk05/BACKUP/ICEF_D92
UnData=`cat /dta/release1/release2/D92tostorageserver1/Un.Data | decrypt -a arcfour -k /dta/release1/release2/D92tostorageserver1/key.kxt`
pData=`cat /dta/release1/release2/D92tostorageserver1/p.Data | decrypt -a arcfour -k /dta/release1/release2/D92tostorageserver1/key.kxt`
ftp -inv 3.58.48.105 << !
user `cat /dta/release1/release2/D92tostorageserver1/$UnData | decrypt -a arcfour -k /dta/release1/release2/D92tostorageserver1/key.kxt` `cat /dta/release1/release2/D92tostorageserver1/$pData | decrypt -a arcfour -k /dta/release1/release2/D92tostorageserver1/key.kxt`
ls
cd /Archives/basefiles/D92/
mkdir `date +%Y-%m-%d`
cd `date +%Y-%m-%d`
bin
prompt
mput *.Z
!
Step3:
cat ftptest.sh | encrypt -a arcfour -k key.kxt > Data.C
echo Data.C | encrypt -a arcfour -k key.kxt > C.Data

Db question set with answers Part 2

Steps to create Database Manually?
1. set ORACLE_SID=<sid> windows
export ORACLE_SID=<sid> UNIX
2. additionally create service in windows
oradim -new -sid <sid> -srvc OracleServicesid -startmode auto/mannual -srvcstart system -pfile <spfile path> -syspwd <password for / as sysdba>
for windows
edit oratab file in /var/opt/oracle with
<DBNAME>:<home directory>:Y/N
this file is read by dbstart
for solaris
to make startmode auto give Y at the end
to make srvcstart system attach the dbstart with rc<n>.d
3. Create parameter file
4. sqlplus / as sysdba
startup nomount
run create database command
5. create additional tablespace
6. create data dictionary views and some additional scripts
7. convert pfile to spfile
8. shutdown and startup
Steps to upgrade Mannually from 9i  to 10g
1. copy parameter,password file to new 10g home location
2. run utlu101i.sql by spooling it to a file
3. do the respective changes according to spool file
change the parameter compatibility to 10.0
keep minimum sizes to memory parameters
shared_pool_size 96MB etc
4. shutdown immediate
5. change the size of redo if less then 4M
increase the size of system file where data dictionaries stored
create sysaux tablespace
6.Point env variables to new location of 10g
ORACLE_HOME
NLS_LANG

3. take backup of oracle home binaries and DBs
4. opatch napply <patch_location>
or opatch apply <patchid>
Steps to clone the Database
1. create environment variables on new system
2. Copy all the files expect controlfile and redo log file to new system
3. change init file parameters as per new systems settings
4. Create controlfile to trace and modify the locations as per new system
5. on new system export oracle_sid
6. sqlplus nomount
7. run modified controlfile of trace on new system
8. recover database until given time
9. alter database open resetlogs
Steps to duplicate db using RMAN on same Server
1. create a passwordfile for duplicate database named as DUP
2. create listener and tns entry for Database DUP
3. copy init file of target and rename it as initdup and edit controlfile location, dbname
4. db_file_name_convert=(target path,dup db path)
lof_file_name_convert=(target path,dup db path)
5. export ORACLE_SID=dup sqlplus / as sysdba startup nomount
6. create spfile from pfile
7. using RMAN for duplicating db
export ORACLE_SID=dup
rman target uname/pass@targetdb catalog uname/pass@catalogdb auxiliary /
duplicate target database to dup;
or duplicate target database to dup until time 'sysdate-4'

DR Setup using RMAN

Configuring the DR Databases
TNSNAMES.ORA File on the primary server PRSERVER:
TEST.DBSUPPORTSERVICES.CO.UK =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = PRSERVER)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TEST)
    )
  )

STTEST.DBSUPPORTSERVICES.CO.UK =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = STSERVER)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TEST)
    )
  )
TNSNAMES.ORA File on the standby server STSERVER:
TEST.DBSUPPORTSERVICES.CO.UK =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = STSERVER)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TEST)
    )
  )
STTEST.DBSUPPORTSERVICES.CO.UK =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = PRSERVER)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TEST)
    )
  )
Relevant Initialisation Parameters on both Production and DR Servers:
*.log_archive_dest_1='LOCATION=M:\Oracle-Databases\TEST\archive'
*.log_archive_dest_2='SERVICE=STTEST.DBSUPPORTSERVICES.CO.UK REOPEN=60'
*.log_archive_dest_state_2='ENABLE'
*.standby_archive_dest='P:\Oracle-Databases\TEST\archive'
*.standby_file_management='AUTO'
*.fal_client='TEST.DBSUPPORTSERVICES.CO.UK'
*.fal_server='STTEST.DBSUPPORTSERVICES.CO.UK'
*.archive_lag_target=900
Configuring the environments as above will allow log replication to continue after a clean switchover so that it is easy to switch back and forth between servers.  For example PRSERVER can become a standby database while STSERVER is primary and vice Aversa.
Creating a Standby Database from the Primary via RMAN On production server:
1.       Launch RMAN to connect to the TEST database and check the current RMAN configuration:
C:\ >set ORACLE_SID=TEST
C:\ >rman target /
Recovery Manager: Release 9.2.0.6.0 - Production
Copyright (c) 1995, 2002, Oracle Corporation.  All rights reserved.
connected to target database: TEST (DBID=1949209861)
RMAN> show all;
using target database controlfile instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'I:\Oracle_Backups\%d_%F.rman';
CONFIGURE DEVICE TYPE DISK PARALLELISM 1;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'I:\Oracle_Backups\%d_%s_%p.rman';
CONFIGURE MAXSETSIZE TO UNLIMITED;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'E:\ORACLE\ORA92\DATABASE\SNCFTEST.ORA';
2.       Backup the current production database to create a standby database:
RMAN> backup database include current controlfile for standby plus archivelog;
3.       Manually copy the backup sets from I:\Oracle_Backups on the production server to I:\Oracle_Backups on the DR Server (location of backups must match on both production and DR).
4.       On the DR Server start up the TEST database in nomount mode:
C:\> set ORACLE_SID=TEST
C:\> sqlplus /nolog
SQL> connect / as sysdba
SQL> startup nomount
SQL> exit
5.       Create the standby database using RMAN (This assumes the database file structures will be identical on both servers):
C:\> RMAN target ‘sys/fluffy@STTEST’ auxiliary /
RMAN> duplicate target database for standby nofilenamecheck dorecover;
6.       Once the DR database is created; you will need to manually add a tempfile:
SQL> alter database open read only;
SQL> alter tablespace temp add tempfile ‘F:\Oracle-Databases\TEST\TEMP01.DBF’ size 500M;
7.       Put the DR database into managed standby mode:
SQL> shutdown immediate
SQL> startup nomount
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect;
8.       On the production database switch logs to initiate replication:
SQL> alter system switch logfile;
The configuration of Dataguard is now complete.
Invoking a DR Standby Database
Overview
There are different methods you can use to invoke a standby database depending on the typical DR scenario you are facing.
Method
 Description
 Scenario for usage.

Database Switchover
 Using this method you can switch backwards and forwards between the primary and DR servers (e.g. so that the primary can become DR and DR can become primary) without having to rebuild either environment. 
 This scenario can be used if both the Primary and Standby Servers are available so that you can connect to both environments simultaneously and perform a clean switchover.

Activating a Standby Database
 This method will activate the Standby Database as the primary database recovering up to the point of the last log shipment.  After activating a standby database as the primary the original primary server becomes obsolete and will need to be rebuilt as a standby database (e.g. you can not just switch the servers back to act as a primary or standby database and will need to rebuild the data-guard environments).
 This scenario can be used if the primary server is not available and you need to force the standby database to become the primary.

Opening the standby Database in Read-Only Mode
 This method involves stopping data-guard replication and opening the standby database in read-only mode for querying.  The database can then be shutdown and reopened in standby mode so that data-guard replication can resume (assuming all required archive logs are still available)
 This scenario can be used if you want to open the standby database temporarily for querying data and then wish to put the database back into standby mode.
The following section describes how to perform each of the above methods of invoking a standby database:
Database Switchover
Using this method you can switch backwards and forwards between the primary and DR servers (e.g. so that the primary can become DR and DR can become primary) without having to rebuild either environment:
On Primary Server:
SQL> alter database commit to switchover to standby;
This may cause the following error to be generated:
ERROR at line 1:
ORA-01093: ALTER DATABASE CLOSE only permitted with no sessions connected
If this does occur then restart the database, as below, before retrying the above command:
SQL> shutdown immediate
SQL> startup
SQL> shutdown immediate
SQL> startup nomount
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect;
The primary server is now configured as a DR standby database.
On DR Server:
SQL> alter database recover managed standby database cancel;
SQL> alter database commit to switchover to primary;
SQL> shutdown immediate
SQL> startup
The DR server is now configured as the primary database.
To switch back you just need to repeat the above process but the other way around (e.g. convert the DR database back to a standby and the primary database back to primary).
Activating a Standby Database
If the primary database is not available the standby database can be converted into the primary database as follows:
SQL> alter database recover managed standby database cancel;
SQL> alter database activate standby database;
SQL> shutdown immediate
SQL> startup
The original primary database is now obsolete and can be rebuilt as a standby database once it is available again.
Opening the Standby Database in Read Only Mode
The standby database can be opened in read only mode for querying and then converted back into a standby database without affecting the primary.
On standby server:
SQL> alter database recover managed standby database cancel;
SQL> alter database open read only;
The standby database is now open and available for querying in read only mode.
To put the standby database back into standby mode:
SQL> shutdown immediate
SQL> startup nomount
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect;
How to check whether the Standby Database is in Sync
On the primary server:
SQL> SELECT max(sequence#) AS "PRIMARY" FROM v$log_history;
On the standby server:
SQL> SELECT max(sequence#) AS "STANDBY", applied
         FROM v$archived_log GROUP BY applied;

The standby database is in sync with the primary database if the above PRIMARY value matches the above STANDBY value where applied = 'YES'

Steps to convert Normal table to partition table

-- Step 01:
Check Whether table ocdw.DEPOSIT_ACCT_INDICATOR_B can be redefined online.
SQL> exec dbms_redefinition.can_redef_table('OCDW', 'DEPOSIT_ACCT_INDICATOR_B');
PL/SQL procedure successfully completed.
-- Step 02:
Create an interim table ocdw.DEPOSIT_ACCT_INDICATOR_B_ which holds the same structure as the original table except constraints, indexes, triggers but add the partitioning attribute.
SQL>@DEPOSIT_ACCT_INDICATOR_B.sql
Later this table can be dropped.
The DDL at table level should also not contain NOT NULL or any constraints. The NOT NULL contraints at table level if defined in the original table then it will be enforced as constraints after completion of all the steps not at table level.
-- Step 03:
Initiates the redefinition process by calling dbms_redefinition.start_redef_table procedure.
SQL> exec dbms_redefinition.start_redef_table('OCDW', 'DEPOSIT_ACCT_INDICATOR_B', 'DEPOSIT_ACCT_INDICATOR_B_');
PL/SQL procedure successfully completed.
If any error encountered while running this process then abort the redifinition process first using below statements:
SQL> exec dbms_redefinition.abort_redef_table('OCDW', 'DEPOSIT_ACCT_INDICATOR_B', 'DEPOSIT_ACCT_INDICATOR_B_');
Resolve the error and restart the redefinition process.
-- Step 04:
Copies the dependent objects of the original table onto the interim table. The COPY_TABLE_DEPENDENTS Procedure clones the dependent objects of the table being redefined onto the interim table and registers the dependent objects. But this procedure does not clone the already registered dependent objects.
In fact COPY_TABLE_DEPENDENTS Procedure is used to clone the dependent objects like grants, triggers, constraints and privileges from the table being redefined to the interim table which in fact represents the post-redefinition table.
SQL>@copy_table_dependents.sql
The content of this sql file is as below:
DECLARE
  error_count PLS_INTEGER := 0;
  BEGIN
  dbms_redefinition.copy_table_dependents('OCDW', 'DEPOSIT_ACCT_INDICATOR_B', 'DEPOSIT_ACCT_INDICATOR_B_',1, TRUE, TRUE, TRUE, FALSE,error_count);
  DBMS_OUTPUT.PUT_LINE('errors := ' || TO_CHAR(error_count));
  END;
/
If any constraints are created on interim table (even NOT NULL), the above PL/SQL will fail.
-- Step 05:
Completes the redefinition process by calling FINISH_REDEF_TABLE Procedure.
SQL> exec dbms_redefinition.finish_redef_table('OCDW', 'DEPOSIT_ACCT_INDICATOR_B', 'DEPOSIT_ACCT_INDICATOR_B_');
-- Step 06:
Check the partitioning validation by:
SQL> Select partition_name, high_value from user_tab_partitions where table_name='DEPOSIT_ACCT_INDICATOR_B';
-- Step 07:
Check index status by
SQL> select index_name , status from user_indexes where table_name='DEPOSIT_ACCT_INDICATOR_B';
-- Step 08:
Check the constraints
SELECT owner,constraint_name,constraint_type,serach_condition,status
FROM dba_constraints WHERE table_name='DEPOSIT_ACCT_INDICATOR_B';
Check for the NOT NULL constraints. Any constraint defined at table level on original table is now enforced by system generated constraints.
-- Step 09:
Drop the interim table DEPOSIT_ACCT_INDICATOR_B_.
SQL> drop table ocdw.DEPOSIT_ACCT_INDICATOR_B_;
