SAP WAS Transactions Test

This test monitors the transactions to the SAP web application server, and reports key statistics pertaining to the transactions.

Target of the test : A SAP Netweaver Application Server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each of the Dispatchers and each of the configured server processes of the SAP Web AS.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed

Host

Specify the server for which the test is to be configured.

Port

The port number at which the specified server listens.

UserName

This test connects to a specific SAP web application server instance, and extracts critical metrics from it. Therefore, in the UserName text box, provide a valid j2ee admin user name which the test should use for connecting to the server instance.

Password

Provide the Password that corresponds to the specified UserName.

Confirm Password

Confirm the OS Password by retyping it here.

InstanceName

Provide the name of the application server instance to which the test should connect. For example, if you specify tpp here, then the test will use the login credentials (UserName and Password) provided here to connect to an instance named TPP. To know the available server instances, use the instructions provided in Determining the Name of the SAP Web AS Instance.

ConnectorPort

This test uses the P4 protocol for connecting to the SAP web application server. Therefore, the port at which the P4 protocol listens needs to be specified as the ConnectorPort. To know how to determine the P4 port, use the procedure detailed in Determining the P4 Port.

DispatcherID

This test reports a set of metrics for the Java dispatcher that receives client requests. By default, the cluster ID  of the dispatcher is auto-discovered by the eG Enterprise. Therefore, default option is specified against this parameter. Alternately, if you wish to monitor a specific cluster ID, then you can mention that cluster ID against this parameter. To know the cluster ID of the dispatcher, follow the steps discussed in Determining the Name of the SAP Web AS Instance and P4 Protocol Port .

ServerIDs

Typically, the Java dispatcher or the ICM distributes the client requests it receives to the server processes executing on the Java component of the SAP Web AS for processing.  By default, the ServerIDs are auto-discovered by the eG Enterprise. To monitor specific server processes, specify a comma-separated list of the cluster IDs of these server processes in the ServerIDs text box. To know the cluster IDs of the server processes, follow the procedure detailed in Determining the Name of the SAP Web AS Instance and P4 Protocol Port.

Providing a comma-separated list of server process cluster IDs will ensure that these cluster IDs alone appear as the descriptors of the test. If need be, you can have server process name-cluster ID pairs appear as the test descriptors. To achieve this, the specification in the ServerIDs text box should be of the following format: Server process name:Cluster ID of the server process. For example, if the cluster ID of a server process named Server0 is 12621850, then you can specify the ServerID in the format: Server0:12621850.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Active transactions

Indicates the number of transactions that are currently active.

Number

 

Commit transactions

Indicates the number of transactions that have been committed since the last measurement period.

Number

 

Rollback transactions

Indicates the number of transactions that have been rolled back since the last measurement period.

Number

Ideally, there should be fewer rollbacks happening, as rollbacks are costly operations on the database.

Suspend transactions

Indicates the number of suspended transactions since the last measurement period.

Number

 

Timedout transactions

Indicates the number of transactions that have timed out since the last measurement period.

Number

If the value of this measure is very high, then consider resetting the Timeout period for transactions.
