All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 2 Objectives -The main objective is to determine the Maximum number of MDB connections that can accomplished in a Distributed Deployment. This is particularly important when large number of Distributed State Machines (dsm) are to be deployed -In addition, the test is also geared to determine the limit of maximum number Ingres Sessions based on memory constraints

All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 3 Out-of-Box -Ingres has been configured for 500 Maximum connections -For Local MDB, Ingres Client is configured with InBound=500 and OutBound=500 -For Ingres Client only setup, In Bound and Out Bound limits are configured as 64.

10 Test 1 -Distributed DSM

11 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 11 Objective -The main objective is to determine in a distributed deployment, the number of distributed DSMs (agent technology) with key components installed, can connect to a Central MDB. -The test is performed with out-of-box Ingres Configuration.

16 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 16 Ingres Client Session Breakdown -There are 8 permanent sessions from the Ingres Client. Application Number of Sessions aws_wvgate2 Continues Discovery Manager2 aws_dsm2 ca-notify1 Worldview Agent1 Total Sessions at Start8

17 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 17 Client Connections -If the continuous discovery manager is not installed, this will reduce the number of connections by 2, bringing the permanent connections to 6. -Allow for 4 additional dynamic connections. This will bring the average number of connections to 10. These dynamic connections may be classic 2dmap gui, worldview command line utilities, etc -MDB internally takes up 22 connections. In additional local MDB application takes up 32. The bulk of these are taken up by SevPropCom and Enterprise Management (JMO) -In a typical setup, after 475 connections, out-of-memory condition may be experienced on the local MDB. So the architecture should be designed around 475 max connections

19 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 19 Conclusion -Without any Ingres configuration customization, approximately 42 Agent Technology DSMs can connect to one MDB. -If more than 42 dsms need to be deployed then federated MDB concept should be reviewed

20 Test 2

21 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 21 Objectives -Analyze the impact if the inbound or outbound limit is exhausted -Out-of-box, the Inbound and Outbound limits are set to 64. If this limit is exhausted, it will not be able to connect to the MDB until some connections are released

22 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 22 Test 2 -Connect to Highly Available remote MDB from Ingres Client setup -Setup a Loop to connect remote CORE (mdb) until it fails to connect -Review Ingres Connections -Out-of-box Inbound an Out bound limit set to 64.It cannot exceed this limit

30 Test 3 -Out-of-Memory Test

31 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 31 Objectives -The main objective is to exhaust the Ingres Connections until out-of-memory condition is experienced. Then ascertain the maximum number of active connections.

33 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 33 Out-of-Memory -Attempt to launch SQL from local MDB server fails due to out-of-memory condition

34 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 34 Ingres Sessions Review on Local MDB -Stop awservices to release 4 sessions. -This shows Ingres Sessions after stopping awservices Confirms failure due to out-of- memory

35 © 2005 Computer Associates International, Inc. (CA). All trademarks, trade names, services marks and logos referenced herein belong to their respective companies. 35 Conclusions -After connection of approximately 475 sessions, no more connections will be possible to the MDB due to out of memory condition.

36 Test 4 -DSM Session Breakdown
