5. www.regoconsulting.comPhone: 1-888-813-0444 5 Items driving performance are typically resolved by adjustments to the application configuration, application server, and database environment. Key levers we can use to improve performance Functional & Technical Hardware InvestmentProcess Changes App Configuration Job timing Job conflicts Page layout Security model Slice settings Period settings Code optimization Inactivate resources Purge investments DB Environment Memory Cores Shared usage Storage speed Query performance Long sessions Maintenance jobs Parameters Reporting demand App Server Memory Cores JVM Architecture JVM Memory JVM GC Settings Maintennance

6. www.regoconsulting.comPhone: 1-888-813-0444 6 Application configuration issues typically require a mix of both functional and technical changes. The changes are often caused by suboptimal configurations. ● Job timing ○ Leverage evening downtime window but coordinate with DBA ○ Run database and system maintenance jobs after Clarity jobs complete ○ Avoid large data changes (e.g. post timesheets regularly) ● Job conflicts ○ Avoid conflicts between slicing, posting, etc. ● Security model ○ Use global rights if possible ○ Minimize the use of instance rights ● Page layout ○ Browsers and the application have ‘real limits’ to what they can digest ● Slice settings ○ Minimize slice time ranges ● Period settings ○ Close time and fiscal periods. ● Code optimization ○ Suboptimal SQL and Gel is the number one issue we see! Application configuration tends to force functional settings

7. www.regoconsulting.comPhone: 1-888-813-0444 7 Application server issues typically an increase in the capacity of the application servers. Key indicators of an application server issue are high application cpu and heap dumps. ● Memory ○ 6 GB for the app JVM is great – but 7 GB is worse ○ Never less than 2 GB for the BG – typically 2.25 GB is good ● Cores ○ 1 Core per JVM or BG ○ 1 Core for the OS ○ 1 Core for GC ● JVM Architecture ○ 1 or 2 BGs ○ 50 to 150 concurrent users per JVM ○ Leverage a XOG / Admin / Scheduler JVM ● JVM GC Settings ○ Parallel garbage collection if more than 1 core ● Maintenance ○ Weekly restarts may be necessary, but can typically be avoided if architecture sized correctly. Application server issues are hardware related

8. www.regoconsulting.comPhone: 1-888-813-0444 8 Database issues are often a mix of hardware, customization, and maintenance. ● Memory ○ Most common problem. Clarity LOVES memory! ● Cores ○ Uncommon problem – start with tuning and memory ● Shared usage ○ Applications need to ‘play nice’ ● Storage speed ○ Clarity demands a high speed SAN. Memory compensates for IOPs…. ● Query performance & Long running session ○ Second most common problem! Efficient SQL is critical. ○ Sessions persist after there are not visible on the application! ● Maintenance jobs ○ Do not run standard Oracle database stats job ● Parameters ○ Contact Rego for environment specific database parameters ● Reporting demand ○ Monitor and plan for Crystal and Webi reporting Database server issues are typically tuning related

9. www.regoconsulting.comPhone: 1-888-813-0444 9 There are a variety of sources providing key information on performance. Rego Exchange has portlets that help monitor jobs, processes, and database (Oracle) performance. Performance data exists in a variety of data sources Log & Config Files App Logs BG Logs App Access Logs Process engine Database Reports Oracle advantages Deadlocks Waits Physical IO Cache Memory Long sessions Top SQL by CPU Top SQL by IO Table fragmentation Table configuration Infrastructure Diagrams Confirm Cores Confirm Memory Confirm IO Confirm Network GC Performance

10. www.regoconsulting.comPhone: 1-888-813-0444 10 Addressing performance issues is an iterative process!!! Start with the low hanging fruit. Issues often ‘mask’ the more systemic issues.

12. www.regoconsulting.comPhone: 1-888-813-0444 12 Symptom ● Application heap dumps, out of memory warnings, and periodic slowness ● Database appears to be healthy Clues ● Clarity 13 requires additional capacity (memory & cores) ● JVMs heaps were 1.5 GB or the app and 1.0 GB for the BG ● Application JVMs spending significant time garbage collecting ● Symptoms appear during peak usage time ● Database is healthy Resolution ● Increase memory for JVMs to 6 GB for the apps and 2 GB for the BB ● Increase cores to 1 core per BG, 1 core per APP, 1 core for OS, and 1 core for GC. ● Add JVM for XOGs / Admin / Scheduler Result ● Stable Dev environment ● Pushing to production ● If cores are limited, try memory increase first and watch GC performance Real-world Case: Application Sizing

13. www.regoconsulting.comPhone: 1-888-813-0444 13 Symptom ● Frequent & persistent application slowness ● Database CPU and application CPU are inconsistent Clues ● Long running sessions on the database (more than a few minutes) ● Blocking sessions ● High physical I/O Resolution ● Moved to the Clarity stats job (Oracle) nightly & disabled the Oracle cron job ● Increased the size of the database cache (PGA and SGA) ● Rebuilt indexes associated with long running SQ Result ● Stable and consistent production environment ● Exposed additional queries that needed to be tuned ● Exposed need to establish tuning and maintenance process Real-world Case: Database I/O and Tuning

14. www.regoconsulting.comPhone: 1-888-813-0444 14 Symptom ● Select users long waits with select portlets and pages ● Periodic system slowness ● Oddly high database CPU Clues ● Long running sessions on the database (more than a few minutes) ● Top SQL includes portlet queries with poor SQL Resolution ● Tuned the queries causing the issue ● Changed the page configurations to render on filter only ● Set default filter for the portlets Result ● Improved portlet speed ● Eliminated long running sessions (led to system issues) ● This can also apply to WebI and reports Real-world Case: User Portlets and Configuration

16. www.regoconsulting.comPhone: 1-888-813-0444 16 ● Event Based ○ This type of Interface is triggered by event in the system. (Either something got created or updated or deleted) ● Batch ○ This type of interface is scheduled and triggered at a set time (nightly or at certain interval, etc.). Since, batch interfaces will handle multiple instances, you want to address transaction managements (what happens when a record fails – one fail, all fail?) ● Manual ○ This type of Interface is manually started by the user when they are ready for data transmittal. Integration Basics – Triggers

17. www.regoconsulting.comPhone: 1-888-813-0444 17 ● Flat File ○ A.CSV file ftp'd onto a server can be pulled into Clarity. The file can be processed by custom GEL script that can be scheduled or started manually. (This is CA’s preferred method of integration for the On-Demand Clients) ● Web Services ○ XML based messaging that makes a call via URLs, or over HTTP to request data from or push data into clarity. This method could leverage GEL scripts, Java classes, or Stored Procedures in the DB ○ This is the most common approach used by any industry for Integrating different systems. Most of the big software vendors like SAP, Oracle, HP, CA have web service API’s developed for bi-directional data exchange with their systems. ● Database Links ○ Establish a link from the Clarity DB to another system database and just pull data from one system to another using a stored procedure or SQL statement. Best practice in this form is to create a “view” in the source system vs. the core tables. (This is not an option for the On Demand Clients) ● Third Party Tools ○ Leverage a third party integration tool like ITROI, etc. to build integrations. ○ Leverage an integration service – Pervasive or Task Top Integration Basics – Methods

Upon approval in your Financial System, Clarity needs to be updated so that the Project Plan is sent over to your Timekeeping system. How would you implement this? Quiz

20. www.regoconsulting.comPhone: 1-888-813-0444 20 ● Simpler is Better ○ With integrations, the more complex the interface is the more difficult it will be to build and maintain. One Direction vs. Bi-Direction is simpler. ● Get it Right the First Time ○ We love agile and iterative development, but not when building an interface. Interfaces are best done with solid waterfall requirements and signoffs. ● Integrations are recurring jobs. ○ Integration are not for performing one time data loads. Integrations are for exchanging data between two systems on a regular basis. ● Data Ownership is Key ○ You must determine which system is the “master” vs. the “slave” of the data. One source must be the owner of the data in case there is a conflict. Do not make the mistake to think Clarity will be the “source” of everything. Leverage other systems to pull summarized data vs. all detail. Keys to Success

21. www.regoconsulting.comPhone: 1-888-813-0444 21 ● Error Handling / Transaction Management ○ Errors are inevitable when two different systems are being integrated. Therefore plan to developing an error handing mechanism to handle data errors, connectivity errors, and system outages. ○ Equally important is transaction management and performance considerations ● Trial First to Avoid Errors ○ Before you build the complete interface – try a semi-automated load to ensure the “process” you have defined is correct. ○ Have a Testing Environment. It is really important to have test environments that mirror the productions as much as possible and that the data is representative of actual production data. Keys to Success
