WhatsApp Messenger: Android

davidaank — Tue, 18 Oct 2011 04:06:23 +0000

Hey, I just downloaded WhatsApp Messenger on my Android. It is a Smartphone Messenger which replaces SMS. This app even lets me send pictures, video and other multi-media! WhatsApp Messenger is available for Android, iPhone, Nokia and BlackBerry and there is no PIN or username to remember – it works just like SMS and uses your internet data plan. Get it now from http://www.whatsapp.com/download/ and say good-bye to SMS.

C:\Program Files\IBM\SQLLIB\BIN>db2

Command Line Processor for DB2 ADCL 9.1.0

You can issue database manager commands and SQL statements from the command
prompt. For example:
db2 => connect to sample
db2 => bind sample.bnd

For general help, type: ?.
For command help, type: ? command, where command can be
the first few keywords of a database manager command. For example:
? CATALOG DATABASE for help on the CATALOG DATABASE command
? CATALOG for help on all of the CATALOG commands.

To exit db2 interactive mode, type QUIT at the command prompt. Outside
interactive mode, all commands must be prefixed with ‘db2′.
To list the current command option settings, type LIST COMMAND OPTIONS.

For more detailed help, refer to the Online Reference Manual.

Data Filtering current_date -7 days

davidaank — Wed, 30 Jun 2010 12:54:06 +0000

I run query REFRESH TABLE DEV.MQT_AAA_APN_D_H7 on the sql tools such as toad is running well but i get errors when refresh table on db2 console.

This query MQ tables (MQT_AAA_APN_D_H7):
select DAY_ID, PRODUCT_ID, HIT, sum(sendkbytes) as SENDKBYTES, sum(receivekbytes) as RECEIVEKBYTES from DEV.aaa_apn_d_t WHERE day_id > cast(replace(char(current_date - 7 days),'-','') as integer) group by DAY_ID,PRODUCT_ID;

bash-3.2$ db2 connect to mydb user myuaix using P@ssW0rd Database Connection Information Database server = DB2/AIX64 9.5.1 SQL authorization ID = MYUAIX Local database alias = MYDB

bash-3.2$ db2 "REFRESH TABLE DEV.MQT_AAA_APN_D_H7" DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned: SQL0420N Invalid character found in a character string argument of the function "INTEGER". SQLSTATE=22018

The problem is the following expression: char(current_date – 7 days)
It will be interpreted differently on different environments

Code:
values (char(current_date - 7 days))

1 ---------- 04/20/2010

You need to standardize it so it will always return the same value: char(current_date – 7 days,ISO)

Code:
values (char(current_date - 7 days,ISO))

Limit the number of rows in DB

davidaank — Wed, 30 Jun 2010 10:24:16 +0000

How can I limit the number of rows in DB2, MySQL, Oracle, SQL Server

in Oracle:
SELECT * FROM Table_Name where rownum <= 5

in DB2:
SELECT * FROM Table_Name fetch first 5 rows only

in MySQL:
SELECT * FROM Table_Name limit 5

in SQL Server:
SELECT TOP 5 * from Table_Name

hopefully useful…

How to create a self-signed SSL Certificate

davidaank — Fri, 18 Jun 2010 11:55:20 +0000

The following command steps I did to generate SSL Certificates on AIX Version 5.3!

Step 1: Generate a Private Key
openssl genrsa -des3 -out server.key 1024

Step 2: Generate a CSR (Certificate Signing Request)
openssl req -new -key server.key -out server.csr

Step 3: Remove Passphrase from Key
cp server.key server.key.org openssl rsa -in server.key.org -out server.key

Step 4: Generating a Self-Signed Certificate
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Step 5: Installing the Private Key and Certificate
cp server.crt /etc/opt/freeware/apache/conf/ssl.crt cp server.key /etc/opt/freeware/apache/conf/ssl.key

Step 6: Configuring SSL Enabled Virtual Hosts
SSLEngine on SSLCertificateFile /etc/opt/freeware/apache/conf/ssl.crt/server.crt SSLCertificateKeyFile /etc/opt/freeware/apache/conf/ssl.key/server.key

Step 7: Restart Apache and Test
apachectl stop apachectl startssl

SQL0668N Operation not allowed for reason code “x” on table

davidaank — Tue, 15 Jun 2010 11:41:34 +0000

When you loading all database with db2move command, propably most of the tables being loaded are in pending state. To check which ones, execute SQL statement:

SELECT tabname,status,const_checked FROM syscat.tables WHERE status=’C’
This command will list all tables in pending state

Reson code:

* “1″ – table is in pending state – to fix this execute
SET INTEGRITY FOR table_name IMMEDIATE CHECKED

* “3″ – previous load operation on this table failed. You have to terminate or restart previous load command
