MIGRATION | From Oracle to Microsoft SQL Server

15
Migrate to ICM 7.10 on Oracle Database
Move over to ICM 7.10 on Microsoft SQL Server / Azure SQL Database
1. Remove Oracle Specifics from Java Code
2. Convert Functions into Procedures
3. Extract Queries into Query Files
4. Implement Dialect
5. Use JUnit Query Test Framework to write query tests!
MIGRATION STEPS | From Oracle to Microsoft SQL Server

16
Remove Oracle specifics
'nvl(' | 'trunc(' | 'asc nulls' | 'desc nulls' | 'to_date(' | 'bitand('
ProductVariationMappingRule.java UPDATE statement:
…"SET p.typecode=BITAND(p.typecode, -1 -32) …
…"SET p.typecode="+JDBCUtils.sqlFunction("bitand","p.typecode","(-1 -32)")+"
MIGRATION STEPS | Remove Oracle Specifics from Java Code

17
Convert all functions into procedures which changes DDL or DML
MS SQL functions can’t change DDL or DML
Convert all PL/SQL packages into functions
MS SQL doesn’t support PL/SQL packages
MIGRATION STEPS | Convert Functions into Procedures

18
Iterator<ProductPO> pIterator = pH.getObjectsBySQLWhere("sku=? and domainID=?
and rownum=1", new String[] { sku, aDomain.getUUID() }).iterator();
Iterator<ProductPO> pIterator = null;
try
{
Map<String, Object> params = new HashMap<>();
params.put("SKU", sku);
params.put("DomainUUID", aDomain.getUUID());
productsIterator =
appProvider.get().getQueryExecutor().executePageableQuery("product/GetProductBySKUSimple"
, params);
if (productsIterator.hasNext())
{
ProductPO p = productsIterator.next();
aProduct = productViewProvider.create(p.getUUID(), aDomain.getUUID());
}
} …
MIGRATION STEPS | Extract Queries into Query Files

19
Remove Oracle specifics by using ANSI SQL or implement Microsoft dialect
<?xml version="1.0" encoding="UTF-8"?>
<query>
<processor name="JDBC“/>
<template sqlDialect="Oracle">
…
</template>
<template sqlDialect="Microsoft">
…
</template>
</query>
MIGRATION STEPS | Convert Query Files
SELECT
<sql-dialect name="Oracle">
sysdate FROM DUAL
</sql-dialect>
<sql-dialect name="Microsoft">
GETDATE()
</sql-dialect>

20
Use JUnit Query Test Framework to write query tests!
MIGRATION STEPS | Write Query Tests

21
Data Definition (DDL)
>750 tables
16 views
>2100 indexes
Data Manipulation (DML)
>150 stored procedures
~100 functions
<10 PL/SQL packages
(transformed into MS SQL functions)
Data Query (DQL)
750+ queries
65 of them are
Oracle/Microsoft
specific
