SyteLine Database Optimization and SQL Tuning
The SQL Server database is the performance foundation of every SyteLine environment. Database optimization for SyteLine requires understanding both SQL Server internals and SyteLine's specific query patterns. Generic SQL Server tuning advice often misses SyteLine-specific considerations like the Mongoose connection pooling model, the IDO query generation patterns, and the impact of SyteLine's extensive use of SQL views. This guide provides SyteLine-specific database optimization techniques.
SQL Server Configuration for SyteLine
SyteLine's SQL Server instance should be configured specifically for its workload characteristics: mixed OLTP and reporting queries, heavy use of views and joins, and burst activity during batch processing. Key settings include maximum memory allocation (leave 4-8 GB for the OS and Mongoose), maximum degree of parallelism (set MAXDOP to match SyteLine's recommendation for your version), and tempdb configuration for the heavy temp table usage SyteLine generates.
- Set SQL Server max memory to total RAM minus 4-8 GB reserved for OS and application server
- Configure MAXDOP per Infor's recommendation—typically 4 for most SyteLine workloads
- Create multiple tempdb data files equal to the number of CPU cores (up to 8) for reduced contention
- Enable query store to track query plan regressions that cause sudden performance degradation
Index Maintenance and Optimization
SyteLine databases with heavy transaction volumes develop index fragmentation rapidly. Fragmented indexes cause increased I/O for every query. Implement an index maintenance strategy that rebuilds heavily fragmented indexes (>30% fragmentation) and reorganizes moderately fragmented indexes (10-30%) during maintenance windows. Use Ola Hallengren's maintenance solution or a similar proven framework rather than building custom maintenance scripts.
- Implement automated index maintenance running nightly for transaction tables with high insert/update volume
- Rebuild indexes above 30% fragmentation and reorganize between 10-30% using adaptive thresholds
- Update statistics on all tables weekly—SyteLine's dynamic query patterns need current cardinality estimates
- Monitor index usage statistics to identify unused indexes that slow writes without benefiting reads
Query Tuning for SyteLine Patterns
SyteLine-specific query tuning targets the patterns generated by the IDO layer: dynamically constructed WHERE clauses, multi-table view joins, and aggregation queries from reporting. Use the Query Store or Plan Cache to identify the most expensive queries by total CPU or total duration. For each expensive query, examine the execution plan for table scans, hash joins on large tables, and excessive sort operations that indicate optimization opportunities.
- Use Query Store Top Resource Consuming Queries report to identify optimization targets systematically
- Address table scans by adding indexes on the filter columns used in the IDO-generated WHERE clauses
- Investigate parameter sniffing issues when the same form performs differently for different users or filters
- Consider indexed views for complex joins that power high-frequency forms and reports
