How and where do we monitor JAVA stack

[Former Member]

Hello All,

A small query and this is an interview question.

1>For monitoring ABAP systems we have the option of RZ20(CCMS) and the system logs .

In the same way where do we monitor JAVA stack and its errors (not the java based logs i am talking about (server<n>/log/defaulttrace<n>.trc) ..

Any one has any idea

Rakesh,

You can monitor the Java stack of XI using Visual Administrator.

The SAP J2EE Engine 6.20 Visual Administrator is a graphical user interface (GUI) that

enables the administration of the whole cluster, of the cluster nodes, and all modules

running on them. The Visual Administrator is written in the Java programming language

and can be run in any environment where a Java Virtual Machine is available. It enables

remote monitoring and management of the cluster, and for each cluster element, and

enables the system administrator to monitor all managers and services working on each

node in a single GUI. The current limitation, in terms of size, for a cluster which can be

administered with the Visual Administrator is eight nodes. When you have more, use the

Telnet as an alternative. The Visual Administrator includes functions for:

u2022 Obtaining general information about a service or manager (for example, its name,

group, and so on)

u2022 Administering and changing the properties either specific or common for each

service or manager

u2022 Runtime administration and control

u2022 Deployment of applications on all cluster elements

u2022 Log viewing

There are lot of other documents available on sdn on this.

Hi,

Java stack monitoring can be done in Runtime Work Bench.

In RWB, you can have Message Monitoring and Component Monitoring.

In Message Monitoring, we can find the the message with status and in "Audit Log" we can have a complete log of processing done for that message. And in Compnent Monitoring, you can find the statuses of all components in Integration Server.

hi,

For all the components monitoring, we have RWB.

Here you have all the info regarding that.

Hi,

the XI runs on an Application Server with double stack (JAVA/ABAP).

Some components of XI runs on JAVA and some on ABAP:

JAVA:

Integration Builder

SLD

Adapter Engine

Runtime Workbench

ABAP:

BPE

Integration Engine

Abap stack

Integration engine(IE) and Business Process Engine(BPE)

Java Stack

Adapter Engine(AE)

SLD,IR,ID,RWB

Abap stack is monitored using sxmb_moni / sxmb_moni_bpe

Java stack is monitored by using Message monitoring, End-End monitoring, Component Monitoring, Performance monitoring from RWB.

Hi rakesh,

If you are satisfied..please close the thread and award points.

Hello All,

Thanks to all for updating the message .

1>I am satisfied with the answers given , but which are completely describing about XI system .

Monitoring ABAP from SXMB_MONI & JAVA from tools of it (RWB,IR& ID) ..

2>But my actual question is relating to general monitoring concerning with NW04s systems in case of non XI systems which has both ABAP & JAVA stack .

Normally for ABAP side we have RZ20 to check the status of all MTE objects and SM21 to check the system logs ....the same way where to check the java side monitoring for NW04s systems .

The actual Inteview question is

1>How do you monitor java stack if it is two tier systems(Dual stack -->ABAP+JAVA (NW04s) systems) .?

Best Regards

Rakesh
