  • 1. New England Data Camp v1.0It is all about the data! Denny Lee, Senior Program Manager SQL Customer Advisory Team - Microsoft Corporation
  • 2.  Learn how to ensure a predictable Reporting Services deployment in your environment Learn about the following as relates to Reporting Services  Backup/restore  Security/authorization  Scale/performance/high availability  Upgrade Approach  Provide the technical knowledge needed to make sound decisions  Provide lessons learned from Real Customers Thanks to Lukasz Pawlowski - SSRS
  • 3.  Works on the largest, most complex SQL Server projects worldwide  US: NASDAQ, Progressive, Premier Bankcard, Hilton Hotels  Europe: Barclays Capital, Danske Bank, McLaren, Bwin  Asia/Pacific: Korea Telecom, GMarket, Japan Railways East, China Mobile  LATAM: Banco Itau, Oi  Strategic ISVs: SAP, Siebel, JDE, PeopleSoft, GE Healthcare, SunGard, Siemens, Dynamics and more Drives product requirements back into SQL Server from our customers and ISVs Shares deep technical content with SQL Server community  SQLCAT.com  http://blogs.msdn.com/sqlcat  http://blogs.msdn.com/mssqlisv  http://technet.microsoft.com/en-us/sqlserver/bb331794.aspx
  • 4.  IT Pros who are new to Reporting Services  Examples of how to use Reporting Services  Understanding architecture & deployments  Provide the knowledge building blocks needed to understand Reporting Services IT Pros with existing deployment of Reporting Services  Make SSRS more efficient and predictable  Learn from others  Validate your work  Fill in any gaps in your knowledge of how SSRS works Slide deck that is a valuable reference tool  Contains many tips & tricks Detailed understanding of SSRS = sleep better at night
  • 5. • Reporting Services 101• Backup/Restore• Security• Monitoring and Planning• Deployment Topology• Upgrade• Tribal Knowledge
  • 6.  People lack understanding of BI solutions  Need to understand key requirements of the user base ▪ E.g. ‘…they replaced pivots with SSRS, and then stumbled during deployment…’ Business Intelligence quick guide  Managed & Ad-hoc Reports = Reporting Services  Dashboards = Windows SharePoint Services ▪ Use SSRS, Excel Services, PPS to provide content  Scorecards = Performance Point Server (PPS)  Analysts = Pivots = Excel Services
  • 7. SharePoint Report SSMS Viewer Report Viewer Web Part Web Service Proxy Data Sources Web Services & URL Access Security Services Report Server Report EngineOutput Formats Data Processing Security Delivery Targets (E-mail, SharePoint, Custom Rendering Scheduling & Delivery Custom Custom Report Item RDCEVisualization Customized RDL SQL Server Catalog

  • 10. Client Application Report Server Report Catalog “Get & Run Report” RSDB Report Compiled Definition Metadata Session Word/Excel/ Execution HTML/PDF RSTempDB Snapshot Report Data Session Report Data
  • 11. WMI Report Server Report Catalog Setup SSRS WMI Provider SSRSConfiguration Manager Config Files IIS/HTTP.SYS
  • 12. Client Application Report Server Report Catalog Symmetric Key (SK) RSDB PubK1(SK)UserNamePassword SecretConnection String SK(Secret) Service Credentials (C1) Public Key, Private Key (PubK1) (PriK1)
  • 13. Importance Items to BackupCritical • Report Server Databases • Symmetric Key • SharePoint Databases • Custom ExtensionsImportant • Configuration Files • RSTempDB • IIS Settings for RS 2005Nice to Have • RDLs • SSL Certificates Standard backup/restore SQL database techniques Don’t forget to backup your SharePoint databases as well!
  • 14.  Configuration files Rsreportserver.config Rssvrpolicy.config Rswebapplication.config Rsmgrpolicy.config Reportingservicesservice.exe.config Machine.config Web.config (for RS & RM)  Recover by COPYING settings into default .config files  Use RS Configuration Tool or WMI to recover: ▪ RSDB connection information (stored encrypted) ▪ URL & SSL Settings (stored also in HTTP.SYS) Symmetric Key  Encrypts report data source settings  Use Report Services Configuration Tool or rskeymgmt.exe to backup/restore  Keep backup in secure place and do not forget the password!
  • 15.  Start with focusing on data security  Do not expose sensitive data in data centers  Expose the minimum set of data required  Audit data access Report data sources  Be careful which credentials are stored in report data sources ▪ Use read-only accounts! ▪ We wary of unnecessary use of Windows Integrated ▪ Review credentials options to ensure report authors are not abusing user’s credentials  Use Shared Data Sources ▪ Control connection strings & credentials ▪ Minimize management overhead Data level security  Use Kerberos delegation if you need end to end data security  Use User!UserId in reports to identify the user within a report  Parameters are not a security mechanism!
  • 16.  Use SSL  Protects report contents & credentials  Performance is not an issue Limit which machines can access your server  Consider IPSec  Block undesired IP address ranges Do not use Anonymous  Identify the abusive users and prevent future abuse  Minimally have one user id for each network entry point Proxies and Authentication Persistence do not mix  Disable authentication persistence if using proxies Watch out for common cross server authentication issues  http://support.microsoft.com/kb/871179  http://support.microsoft.com/kb/896861 (Detailed blog post)
  • 17.  User authentication  Kerberos is better than NTLM  Kerberos requires setting SPNs and is harder to configure Authentication is extensible  ASP.NET Forms authentication sample  Any custom authentication scheme is available  Consider infrastructure solutions like Forefront or IAG ▪ Implement various authentication protocols (e.g. SSO) Authorization  Use Active Directory groups to minimize churn as users  SSRS Security Roles are customizable - make them relevant to your user base  Authorization is extensible Credentials – Lowest Privilege Possible  Service Account should be a low privilege domain account  Set the Unattended Execution Account Allow users only the minimal permissions they need  Don’t manage reports from the SSRS server box…
  • 18.  Auditing Report Access  Use the Execution Log Table (ELT)  Copy information from ELT to your own databases  Stores the user, report & parameter combination as well as success/failure Auditing all operations  Use SSRS Trace Logs with Verbose setting  Data Access use data source auditing Save off Log Files to secure location  LogFile location is configurable is SSRS  Use a write only location  Archive log files so they are not automatically deleted
  • 19.  Keep configuration settings in synch  Tools like IIS Manager or Service Control Manager easily get settings out of synch  Use SSRS Configuration Manager or WMI Provider instead  Keep a meticulous backup of IIS & ASP.NET settings that work Extensions & Custom Assemblies  Deploying extensions is tricky – back up config files  Trust authors; do security reviews Moving reports between servers  RS Scripter is widely used Log Files ▪ Execution Log, Trace Log, HTTP Log, Application Event Logs
  • 20.  Understand your scenarios and reports  Scenarios are defined by user personas & usage patterns  Reports are either test reports or actual reports  Tests should isolate Report Server from other systems Reports can overload underlying data source  Determine which reports are most impactful  Optimize these reports – retrieve only required data Execute Performance Tests – before production!  Using Visual Studio 2005 to Perform Load Testing on a SQL Server 2005 Reporting Services Report Server  Database tools (SQL Profiler, sqlcmd scripts, SQL Scaler, etc.)  Synthetic test tools (e.g. VSTS, Precise Insight, etc.) Use appropriate execution options for reports  Reports run “live” by default  Enable caching for frequently run reports  Execution Snapshots are often overlooked ▪ Can be scheduled to run in off peak hours
  • 21.  Monitoring Report Server Performance Task Manager, Event Viewer, Performance console Record performance numbers for later follow up Common Analysis ▪ Report by user type – e.g. is the CEO’s report running quickly? ▪ Rate of failed reports and aggregate # of failures ▪ Low usage reports should be retired ▪ Poor performing reports should be optimized ▪ Aborted or internal errors Windows Performance Counters  CPU, Memory, disk space Performance Counters ▪ CPU (total & service usage) ▪ I/O (page faults, read/write on disk) ▪ Memory utilization (total & service) ▪ Network I/O (read/write, send/receive, bandwidth) RS Performance Objects  MSRS 2008 Web Service: monitors RS performance  MSRS 2008 Windows Service: monitors scheduled operations and report delivery  ReportServer:Service: monitor HTTP-related events and memory management (new)  SharePoint Integrated Mode: monitor RS events in SharePoint integrated mode System Center Operations Manager
  • 22.  Report Catalog (RSDB) contains ExecutionLog and ExecutionLog2  Which reports are long running?  Subscriptions/Interactive?  Live Data or Snapshots?  Balanced?  Patterns for a report  Health of Reports Server Management Report Samples  Populates separate tables / database  Provides SSIS package to extract and populate data  Follow instructions to setup schema and create job  Provides three reports for you to view report activity
  • 23.  Most common deployment is One-Box  SSRS and SQL Server Relational Engine  Great for developing and building something quick (and budget!) ▪ Good performance & scale if not mission critical  But not so good when it comes to production deployments Test environment should be as close to production as possible  Replicate security, configuration, hardware, software, network  Clustering / High availability scenarios Emphasize the need for performance testing  Identify bottlenecks (e.g. Report Catalog, large drop downs, large reports, etc.)  Do Massive Data volume testing  Using Visual Studio 2005 to Perform Load Testing on a SQL Server 2005 Reporting Services Report Server Protect your underlying data sources!  Reports can cause significant load on report data sources  Planning for reporting load up front will save you time

  • 30.  Scalability  Remote Report Catalog  SSRS 2008 can scale up significantly before needing to scale out ▪ Scale up SSRS 2008 to 16 cores; Scale up SSRS 2005 to 4 cores  Scale-out SSRS 2008 or 2005 to increase throughput ▪ Virtualization works well on larger hardware  Scaling Up Reporting Services 2008 vs. Reporting Services 2005: Lessons Learned High Availability  Scale-out Report Server  Failover Cluster Report Catalog Disaster Recovery  Scale-out Report Servers to include a DR site ▪ Stop/disable the Report Server services to prevent them doing work  Mirror/Log Ship Report Catalog data to the DR site ▪ Will need to manually fail over to this database server ▪ Database Mirroring and Log Shipping Working Together
  • 31.  Great for overall portal and collaboration experience  Information Workers access reports like any Office document ▪ Reports, data sources, report models are stored in document libraries ▪ Shared security model ▪ Features Supported by Reporting Services in SharePoint Integrated Mode  Supports Windows SharePoint Services 3.0 or Office SharePoint Server 2007 Report Metadata is stored in WSS Content DB Configuration can be a challenge  Read the White Paper: SQL Server Reporting Services integration with SharePoint Products and Technologies  Read the documentation: Configuring Reporting Services Use Trusted Account mode  Allows Windows users to access SharePoint  DOES NOT require Kerberos delegation for the deployment  No loss of functionality if using stored credentials in data sources

  • 33. Custom Application• Firewalls throughout environment toprotect data• Point of entry: custom application• Point of entry: enforce access rights•Internet users can query read-onlydata replicated and cleansed fromoriginal data source•Good reference: Planning forExtranet or Internet Deployment
  • 34.  Pre-Upgrade Check list  Upgrade Advisor  Backup/Restore encryption keys  Backup configuration files  Move databases  Backup customizations (especially extensions) SSRS 2008 does not use IIS  Upgrade automatically ports IIS settings All published reports continue to run after an upgrade RS Catalogs  Upgrading SSRS usually means DB schema changes ▪ Before upgrading, plan for roll back ▪ Upgrading a Reporting Server Database ▪ In a scale-out all servers must be at same patch level Considerations for Upgrading Reporting Services
  • 35.  Custom extensions  Not all are supported  Need to re-write custom rendering extensions using new Rendering Object Model  Security and Rendering extensions block upgrade ▪ Unconfigure the extension, upgrade, then reconfigure extension ▪ Blocking behavior prevents broken servers after upgrade and unexpected development costs due to upgrade Inventory & test extensions before upgrade  Save configuration settings for extensions  Ensure reports using extensions are actually working  Find problems with extension configuration quickly Move extensions & assemblies after upgrade  Major Version upgrade creates a new installation folder  Extensions and assemblies are not moved by upgrade
  • 36. Tips for Saving You Time
  • 37.  Tips & Tricks  Blogs & Resources  First steps after install  Scripting  Report Design  Report Parameters  Managing Subscriptions
  • 38.  CodePlex – Samples!  http://www.codeplex.com/ Blogs  http://blogs.msdn.com/sqlrsteamblog/  http://blogs.msdn.com/lukaszp/ www.sqlcat.com MSDN documentation  http://msdn.microsoft.com/en-us/library/bb545450.aspx Forums  http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=82& SiteID=1 Connect feedback  http://connect.microsoft.com/ SSRS White Papers  http://www.microsoft.com/sql/technologies/reporting/whitepapers.mspx
  • 39.  Verify configuration  Use SSRS Configuration Manager to view settings Provision users  Explicitly grant security roles to users on folders  Grant Content Manager and System Admin roles ▪ Required on Vista & Windows Server 2008 Ensure browsers are configured correctly on local box  Add RS & RM URLs to IE Trusted Sites on SSRS computer ▪ Required for Vista & Windows Server 2008  Add NTLM auto send enabled in FireFox & Safari Verify SSRS is working  View Report Server & Report Manager  Create a shared data source  Run a report  Login as a low privilege user Execute your backup strategy  Symmetric key back up is essential
  • 40.  Rs.exe is the scripting utility for SSRS Executes VB.Net scripts  No need to compile Exposes the SSRS Web Service endpoints Allows for automating repetitive tasks  Eg. Moving reports from one server to another Samples  http://www.codeplex.com/MSFTRSProdSamples
  • 41.  Before starting to build reports:  Ensure you have the targeted report export formats identified ▪ The design of each report will change how ell it exports to various render formats  Plan your report logic ▪ Build Functions or Custom Assemblies to standardize report logic ▪ Allow you to be operationally efficient  Use parameters and filtering ▪ Few generic reports = easier maintenance  Page breaks on hidden items are ignored
  • 42.  Parameter values queries can cause significant load on report data sources  Design materialized views that reduce query load  Optimize data sets used for parameter values  Parameter values queries execute many more times than report queries Use hidden and internal parameters to validate user input  Design a report with parameters A & B; B is hidden/internal  Let parameter A be set by the user  In the report have all expressions use parameter B  Set the value of parameter B based on the value of parameter A Report Server manages parameter values  After a report is deployed, the server stores a copy of parameters and their values  Changing parameter values in Report Designer and re-deploying DOES NOT update server parameter values
  • 43.  Use the subscription management reports  http://blogs.msdn.com/lukaszp/archive/2007/08/01/monitoring- subcription-status-new-reports.aspx Users will all pick different times to run their subscriptions  Ensure your system can handle this load  May want to deploy dedicated subscription processing servers Sometimes need custom scheduler  GenerateEvent API can trigger a subscription ▪ Call the method from an SSIS package ▪ Build a process to monitor a file location  Build a custom scheduling engine Delivery failures are in the trace logs
  • 44.  In the words of our Customers:  ‘SSRS is easy to deploy and out of the box’  ‘SSRS 2008 makes deployment easier’  ‘Web service provides interoperability’  “If you want to do things not in the box, there are a lot of ways to extend SSRS.”  “Generally, there is a way to accomplish goals”
