After some rumors, Sun announces an agreement to acquire MySql and Oracle announced that it has entered into an agreement to acquire BEA Systems, Inc.

DB2 Backup Script

A database is very usefull but it’s always important to backup very often your data. To do this IBM/DB2 gives you a graphic interface quite simple to use “Control-Center”, but if you want you include this backup in a batch script you must write a backup script without GUI.

In this new I explain how to write a windows script procedure (.bat or .cmd) to backup your DB2 database.

In this sample I considered that you must close your database before backup ( It’s possible to do this in “ONLINE” mode but it’s more complexe — include log file, rollforward…–) and I use a database SAMPLE (it is his name) for this test .

the goal of this scripts is to :

• Quiesce database (close)
• Backup your data
• UnQuiesce database (open)
• Zip backup file
• Clean/Delete old backup rows in DB2 catalogue
• Delete old backup files

Description

A few days ago I had a little problem when I tried to deploy in WAS 6.0 (Websphere Application Serveur 6) an application including a PDF signature.
During the execution of the servlet’s signature, I had the following problem :

java.lang.Exception: java.lang.Exception: java.io.IOException:
Error in loading the keystore: Private key decryption error:
(java.lang.SecurityException: Unsupported keysize or algorithm parameters)

Resolution

This error is caused by the JCE libraries used by the virtual java’s machine executing WAS. This JVM is the standard version and it had a limited support of cryptographie’s algorithme. To correct this you just have to substitute two jar files in teh configuration of the JVM IBM (local_policy.jar et US_export_policy.jar).
This files are in the index $JAVA_HOME/jre/lib/security (for exemple /usr/lib/jvm/jre-ibm/lib/security or /opt/IBM/WebSphere/AppServer/java/jre/lib/security).
You can download this non limited librairies http://www-128.ibm.com/developerworks/java/jdk/security/142/ (file unrestrict142.zip)

When the file is download you had to:

• Decompress the downloaded file
• Verify that this file contains local_policy.jar et US_export_policy.jar
• Stop Websphere
• Save the old files
• Substitute the two files
• Take off again WAS
