This presentation, given at the Cornell Commonspot SIG meeting on March 22, 2006, addresses issues we discovered in moving sites from a test to production server. Content is stored in a per-site Oracle schema, while user identifiers are defined in a per-server schema. When migrating, it's necessary to update user identifiers in the site database. Peter Hoyt and Paul Houle developed a Perl script that examines the database structure, identifies fields that contain user identifiers, and maps them from the old to new server.

8. Stages
1.
Find missing users in production system
2.
Add missing users to production system
3.
Create mapping of test -> production user ids
4.
Get database schema dump
5.
Extract list of user id fields
6.
Update user ids

9. Schema Dump
CREATE TABLE "PSA_SITE"."APPROVAL"
(
"PAGEID" NUMBER(12,0) NOT NULL ENABLE,
"CONTROLID" NUMBER(12,0) NOT NULL ENABLE,
"ITEMID" NUMBER(12,0) DEFAULT 0,
"USERGROUPID" NUMBER(12,0) NOT NULL ENABLE,
"APPROVALTABLELIST" NVARCHAR2(255) NOT NULL ENABLE,
"STATUS" NUMBER(12,0) DEFAULT 0,
"APPROVALDATE" VARCHAR2(20),
"APPROVALLEVEL" NUMBER(3,0) DEFAULT 0,
"APPROVEDBY" NUMBER(12,0) DEFAULT 0,

11. Heuristics II
• Group ids start with 1,000,000
• Look at values to see if a column contains user id’s
• Is it numeric?
• Do the numbers match users and groups?
• LIST columns, ex. *.ITEMUSERGROUPLIST
• Format: “7,12,55”
