Why do customers like iSeries?• Because there’s real value in integration
• Because reliability is a feature, not an option
• Because it supports mixed workloads on a single server, with stability, at high levels of system utilization
• Because it practically manages itself
• Because it’s more secure by design, providing natural defenses against viruses and the vulnerabilities which they attempt to exploit
• Because it’s technology independent, allowing new technologies to be introduced with minimal disruption

Fang Brothers Knitting• Background
– Global textile and apparel manufacturer with headquarters in Hong Kong– Manufacturer for Gap, Ann Taylor, Tommy Hilfiger, and more
• Objectives– Provide more capacity to support company expansion– Improve customer relationship management
• Solution– Two eServer i5 520s
1. i5/OS with RPG-based Garment application to support Hong Kong users and migration from Exchange to Domino mail.
2. One i5/OS partition with Garment application for China and AIX 5L partition to run CRM application from e-Jing -- built with WebSphere and Oracle
Fang Brothers selected the eServer i5 for is scalability, stability, and its ability to consolidate application on one server. eServer i5 delivered the lowest TCO.

Sequence Object
• Another DB2 construct that supports the automatic generation of column values
• Viewed as a superset of V5R2 identity columns• Generated values easily shared across tables• Can create constant sequence to be used as Global DB2 variables• Example:
CREATE SEQUENCE order_seqSTART WITH 1 INCREMENT BY 1 NO MAX VALUE
INSERT INTO orders(ordnum,custnum) VALUES (NEXT VALUE FOR order_seq, 123)
VALUES NEXT VALUE FOR order_seq INTO :hostvar
UPDATE orders SET ordnum = :hostvarWHERE custnum = 123

Column Level Encryption
• Requires the IBM Cryptographic Access Provider 128-bit product• Column Requirements:• Data Type Requirements: BINARY/VARBINARY, CHAR/VARCHAR FOR BIT DATA,
BLOB, and DDS CHAR/VARCHAR with CCSID(65535)• Length Requirements: • Extra 8 bytes & total length must be rounded to 8-byte boundary
(replace 8 with 16, if BLOB or double-byte CCSID)• 32-byte hint can optionally be stored with encrypted value• Example: 6-byte employee id with no hint needs to be stored in a VARBINARY(16)
CREATE TABLE emp(id VARCHAR(16) FOR BIT DATA,name VARCHAR(50))
SET ENCRYPTION PASSWORD = 'protect'
INSERT INTO emp VALUES(ENCRYPT('112233'), 'BOB SANDERS' )
SELECT DECRYPT_CHAR(id), name FROM emp• Native program access:
– Encryption: Use Before triggers to intercept write requests and then have the trigger execute the Encrypt function against sensitive columns
– Decryption: Define SQL View containing decrypt and then open SQL View as a logical file to read unencrypted data
