Hyperion FDM Architecture Analysis Guide
OverviewYou can use the test results described in this document to assist in designing and optimizing your Hyperion System
9 Financial Data Quality Management hardware architecture.
Additional Architecture ConsiderationsHyperion FDM can be deployed over multiple architectural environments. The most common architecture consistsof one web server, one database server, and one or more application servers. The optimal architecture dependson the types of processing conducted in your Hyperion FDM application. As different types of processing are doneon each system component, it is necessary to determine what types of processing will be used most extensivelyin your system to determine the optimal conguration. For example, you may need more web servers if you have
a large volume of users viewing data, or you may need to upgrade your database server if you use extensivewild cards in your mapping tables. Below are the major Hyperion FDM processes you will need to consider whendesigning your system architecture.
Types of System Processes in Hyperion FDM:
Database Server Intensive Tasks Deleting previously imported Hyperion FDM data prior to a load,executing bulk inserts during a load, mapping calculations after a load, report querying
Application Server Intensive Tasks Parsing and reading source les during the load (import text
process), serving Hyperion FDM reports.
Hyperion FDM Web Server Intensive Tasks Serving web pages
Test Lab EnvironmentThe test environment architecture consists of a single web server, three application servers, and one data server.
All servers are dual processor machines with a minimum of 2 GB of RAM.

Data Viewing Concurrency Test (Test #1)
Methodology
1. This testing method is focused on web server processing for an increasing numbers of concurrent users.
2. The test demonstrates the Web Servers ability to interpret and send a high volume of requests and theApplication/Data Servers ability to respond to these requests.
3. The Browser Requests for this test focus on data viewing/retrieval and not on data updating/inserting.
4. The Hyperion FDM Concurrency test comprises the following operations:
a. Log into application
b. Select Maps link
c. Remain logged onto the application
ResultsTest #1 Concurrent Data Viewing Open 500 data consumer connections simultaneously.
This test produced 500 connections during the entire test run. The rst login occurred at 4:21:20 PM and the last
login occurred at 4:25:08 PM. The entire test took 5 minutes and 52 seconds to complete.

Interpreting the Results
Although the test is meant to represent 500 concurrent users, not all of the users are beginning the loginprocess at the same instant. A delay of approximately .5 - 2 seconds was randomly inserted between requestssent to the Hyperion FDM application. This is meant to more accurately simulate real world concurrency. Thesingle web server was the bottleneck in this testing scenario. The Web Server processor averaged 90%utilization during the test runs. The addition of another web server would have improved overall performance.
Performance could also be improved by deploying a more powerful web server.

Data Loading by Database Type Test (Test #2)
Test Methodology
1. This testing method focuses on application and data server update/insert processing for increasing lesize loads.
2. This test demonstrates the performance of each of the databases supported as le sizes increase.
3. The Hyperion FDM Import Workow task comprises the following operations:
a. Login to application
b. Delete existing data records
c. Delete existing data archive records and les
d. Read and parses the specied import text le
e. Write the cleansed import le to database
f. Add new le to Hyperion FDM data archive
g. Execute Bulk Load
h. Execute Hyperion FDM Mapping Rules
i. Update Workow Status
j. Logoff application
4. This test process is repeated using SQL 200, SQL 2005, Oracle 9i & Oracle 10g.
Test ResultsData Loading by Database Type Files ranging from 5000 records to 2 million records were loaded into eachof the supported databases. Load time for the 1 million record loads were as follows: SQL 2005 6.18 minutes,SQL 2000 6.90 minutes, Oracle 10g 11.15 minutes, Oracle 9i 13.43 minutes.

2000K 808 909 1693 3122
The rst graph (next page) shows database import times as le sizes grow. For le sizes 200,000 records
and above both SQL databases perform signicantly better than the Oracle databases. As the le sizes grow
the performance differences become more evident. For le sizes below 200,000 records the performance
differences between all database types was minimal.
The second graph depicts the breakdown of the individual steps of the import process. Although most of theindividual steps have comparable times for Oracle & SQL, Oracle mapping takes signicantly longer than
the same mapping process for SQL. This is primarily due to the fact that Oracle does not support updates onjoined tables. This action requires Oracle to perform cursor updates which take signicantly longer.

Interpreting the Results
SQL databases run signicantly faster than Oracle for high-volume les. Hyperion FDM has been tuned to
optimize performance for data loading, this results in data scanning during loads for Oracle. Performance
testing has resulted in this being the optimal method for Oracle as indexing the required tables resulted in
decreased performance especially as the Oracle database grows in size.

Data Load Performance over Time (Test #3)
Test Methodology
1. This testing method focuses on overall processing time and database size for a typical high-volumemonth-end scenario with a small number of users loading a high volume of data.
2. The test was run 12 times (simulating 12 months) to show the database sizing as well as any possible
performance degradation as database size increases.
3. The Hyperion FDM Import Workow task comprises the following operations:
a. Log into application
b. Read and parses the specied Import text le
c. Write the cleansed import le to database
d. Add new le to Hyperion FDM data archive
e. Execute Bulk Load
f. Execute Hyperion FDM Mapping Rulesg. Update Workow Status
h. Logoff application
4. The test was run once for SQL 2005 and once for Oracle 10g.
Test ResultsData Load Performance over Time Loading one million records each month for 12 months. This test wasrun for both SQL 2005 & Oracle 10g. To enhance performance, separate hard drives on the data base serverwere used to store the mdf/log les for SQL and the table spaces for Oracle.

Data Loading Concurrency Test (Test #4)
Test Methodology
1. This testing method focuses on application and data server update/insert processing for an increasingnumbers of concurrent users.
2. This test demonstrates the products scalability from a data architecture perspective by executing anincreasing number of simultaneous Import workow tasks.
3. The Hyperion FDM Import Workow task comprises the following operations:
a. Login to application
b. Delete existing data records
c. Delete existing data archive records and les
d. Read and parses the specied import text le
e. Write the cleansed import le to database
f. Add new le to Hyperion FDM data archive
g. Execute Bulk Load
h. Execute Hyperion FDM Mapping Rules
i. Update Workow Status
j. Logoff application
Test ResultsData Load Concurrency Test Concurrent data loading (100, 200, 300 users, loading 6,000 records). Timeto complete the 100 concurrent user load process using three application servers was 1:40 minutes for 100users, 3:16 minutes for 200 users, and 4:43 minutes for 300 users.
The les that were loaded during this test run were 600KB. The load requests were sent with an average delay
of 2 seconds between users to more realistically represent a normal monthly process.
The graph on the next page represents average duration for the main import process tasks. By running the testmultiple times for increasing number of users, we can see the linear increase in duration for the import text task.The time to import the text into the Hyperion FDM database becomes larger as more users are simultaneously
attempting to write records to the database.

Interpreting the Results
During this test, the database server was the bottleneck. As can be seen from the graph above, as moreusers were added the items that are database-intensive (Mapping, Deleting, and Indexing) increase linearly.This is due to the database server being overwhelmed with requests to write to the database. This shows thenecessity of ensuring that the database server is properly sized. Adding database processors in this scenario
would not necessarily improve performance as much as using faster hard drives for the database server.
This test was performed on SQL 2005 with the database log and indexing/worktables each set up on separatehard disk drives. In this instance, the recommended database server conguration would be to spread the
database tasks (data storage, logging, and indexing) over multiple data server hard disk drives to improvethe overall database server performance.

System Recommendations
Database Server
Recommended Hardware
Quad P4 processor
1 GB RAM per 75 concurrent users (2 GB Minimum)
Multiple HDD to spread the processing (especially important with Oracle).
Selecting the appropriate data server hardware is critical for optimal performance for the HyperionFDM application. As can be seen from the Concurrent Data Loading Test, the database server canbecome a bottleneck if not properly sized. Even though you can always add more application servers
and improve performance for selected tasks, doing so can quickly overpower the database server.
Database Sizing
Average total disk space per location = .526 GB per month of storage (based on average le size of
95MB & use of 3 custom dimensions). Each additional dimension increases this on average by .025GB. Note: Average disk size recommendations should be adjusted based on estimated average lesize to be loaded, number of custom dimensions in use, and the number of attribute dimensions in
use.
The database le and log le should be on separate physical drives for SQL. For Oracle each
tablespace (Work, Index, Map Seg, and Data Seg) should be on a separate drive.
For improved performance always use the fastest HDD available.
Document attachments will affect total disk space. All attached documents are archived in theapplication le structure and will occupy the same amount of disk space as the original le.
Exported archive les will also affect total disk space. All exported archives reside in the Archive
Restore directory and will occupy the same amount of disk space as the original archive.

Memory Recycling
By default UpStream WebLink version 8.0.6 and beyond (including Hyperion FDM 9.0.2 andHyperion FDM 9.2.0) use IIS memory recycling to force the Microsoft.Net process to recycle memory

when the process reached 250MB (Windows 2003) or 25% of Web Server memory (Windows 2000).These values are based on a Web Server running 2 GB of RAM. For servers running 4 Gig of RAMthese settings should be adjusted to 150 - 200MB (Windows 2003) and 15% of memory (Windows2000). The default memory limit is extremely important to adjust when your server has 4 GB or more
of RAM.By default version UpStream WebLink 8.0.6 and beyond (including Hyperion FDM 9.0.2 andHyperion FDM 9.2.0) use aspnet_state service to store session values while running the IIS memoryrecycling process. This service must be running on the Web Server for Hyperion FDM to operatecorrectly.
Please refer to the Hardware and Software Requirements document for detailed information on hardwareand software.
Application Settings
Data Segments
Prior to creating the Hyperion FDM locations, it is possible to update Hyperion FDM data segments in the
Hyperion FDM Conguration options. This represents the number of data tables within the Hyperion FDMapplication. These data tables are shared by the data load locations. To avoid data locking, this should beset to 5-8 concurrent data loaders per segment (e.g., 600 concurrent data loaders in one Hyperion FDMapplication would result in data segments of 75-120). Note: This setting applies for each Hyperion FDMapplication.
File Sharing PortsA working folder is dened for each application created in Hyperion FDM. All Hyperion FDM application servers
and the data server share this folder. Because of this, le sharing must be enabled between all Hyperion FDM
application servers and the data server. The ports required are listed below. The account that the data serverservice runs under must be able to read from this share. In the case of SQL Server the account running the
MSSQLSERVER service must be able to read from this share.
For File sharing enable ports:
Application protocol Protocol Ports
NetBIOS Datagram Service UDP 138
NetBIOS Name Resolution UDP 137
NetBIOS Session Service TCP 139
If NET BIOS is turned off then use:
Application protocol Protocol Ports
SMB TCP 445
Note: The le sharing ports need to be opened on all the application servers and the data server. These
ports do not have to be opened on the Web server.

Firewall / DCOM Settings
Port 135 must be open on all application servers and web servers to allow for two-way DCOMcommunication.
Unlike most Internet applications which have xed TCP and/or UDP ports, DCOM dynamicallyassignsat run timeone TCP port and one UDP port to each executable process serving DCOMobjects on a computer. Because DCOM (by default) is free to use any port between 1024 and 65535when it dynamically selects a port for an application. Conguring your rewall to leave such a wide
range of ports open would present a potential security hole. Open DCOM port range may be restrictedby changing the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet
Details on restricting DCOM ports can be found in the Microsoft knowledge base article:
http://support.microsoft.com/kb/154596
Details on other issues that may arise when going through a rewall can be found in the Microsoft knowledge
base article:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndcom/html/msdn_dcomrewall.asp
TCP Keep Alive SettingsDetermines how often TCP sends keep-alive transmissions. TCP sends keep-alive transmissions to verify thatan idle connection is still active. Hyperion recommends that this setting be reduced to hour. Details onupdating the KeepAlive settings can be found in the Microsoft knowledge base article:
