SAP update system using Software Update Manager 1.0

When the SAP system was large simple when there was only part of the ABAP 
system, and the words "Java" and "SAP" and no one thought to pronounce
together, the administrator updates the system gradually, slowly, savoring
each step:

1. First, updated utility SPAM/SAINT. This transaction is used for SPAM.
2. Then updated the kernel- SAP Kernel. 
3. If you need to install/update the Add-ons (add-on) then used transaction
   SAINT.
4. Well, in the end, using transaction SPAM queue drew out for packs of one
   or the other system
5. components, and produced imports.

When in the ABAP system has become more of a component, SAP began to
produce (1-2 times in half a year) or packs stacks Support Package Stack (SPS).
This is a set of packages support or rather, recommendations on updating
of all components of the system with the recommended level of the SAP Kernel.
This mechanism has facilitated the downloading, installation and package
tracking support for all components of the system while providing a guarantee
operation of the system after the upgrade.

When JAVA appeared part of the system, update it just fell on the shoulders
of the administrator. 
Originally, it was used for this purpose utility JSPM.

This example updates the systems based on SAP NetWeaver 7.0 (ABAP + JAVA) 

At the moment there is utility Software Update Manager SAP or just SUM.

One of the purposes of SUM is updated ABAP and JAVA stack system.
And if the ABAP system can be updated-the old fashioned way, through
transaction SPAM/SAINT update, JAVA stack system using JSPM already is
strongly discouraged. Only The SUM.

To download the SUM utility 1.0 , you must log on to the SAP Support Portal
at the link http://service.sap.com/sltoolsetthere to link the Software Logistics
Toolset 1.0 "and" General
Information "section to download the latest version (fig. 1).

Figure. 1. Software Update utility Download Manager.

The documentation for the utility is available in the section "Documentation
→ System → Maintenance Updating SAP Systems Using Software Update
Manager 1.0 SP14. When downloading, you must select the desired platform
(operating system and database) (fig. 2).

Figure. 2. Download the documentation for the Software Update Manager.

Download utilities, as usual, via the SAP Download Manager.

To install or update (if an older version of) utility Software Update Manager
.0, you must unzip the downloaded archive into a directory of
SAR \usr\sap\ <SAPSID> \SUM, running the command type
(example, MS Windows):

> SAPCAR-xvf <SUM_archive>. SAR-R \usr\sap\ <SAPSID>

Note the big utility and decompression time decent. :)

The launch takes place on the server side and client side The backend is 
activated through the launch of under User Administrator (for MS Windows)
executable file "\usr\sap\ <SAPSID> \SUM\STARTUP. BAT ' 
 (fig. 3).

Figure. 3. start the server side of the SUM utility 1.0.

The client part is a Java application (fig. 4) that runs through your browser,
the URL resembles the following:

http://<server_host>: 4329

Figure. 4. screen Sample SUM utility 1.0.

Basic requirements: because Software Update Manager uses SAP for Host Agent,
you must manually update. Details can be found here all part of the SAP system
must be running.

Useful SAP notes utility: 
SAP note # 2084104-Central Note-Software Update Manager 1.0 SP14,
SAP note # 2115547-Oracle: Add. Information-Software Update Manager1.0

My feelings from using conflicting utility. I like old soldiers, not knowing
the words love, love to oversee all stages of the process. As for here, indeed,
the work of the utility is going the same as and when on-step update.
The only innovation: creating clone a tablespace with programs (PSAPSR3XXX)
and import updates in it, and then switch to it as primary.
Thus, reduced downtime (down-time) system, but grow requirements
on your hard disk.

JAVA Monitoring

Contents :

1.  Checking the java stack/portal accessibility

2. User load analysis

3. Java Reports – Navigation and usability

4.  Memory consumption and Threads report

5.  Session Monitoring

6.  Logs and Traces (Default trace, Server log etc)

7.  Accessing Management Console

8.  Checking System availability using Management Console(SDM, Msg server,

     Enqueue server, Java nodes etc)

9. Check various logs(work directory logs, jcontrol, default trace, application log etc)

Java Monitoring :

Place the link of the respective java application in the browser and check whether the java application is opening:

For example:

http://baaka888prd.company.com:50000/irj/portal

If java is up and running, a screen similar to below will open.

If the page did not open,

i)  Check  whether there are network issues

ii) Check tablespaces occupancy levels at Oslevel and make sure sufficient 

    space is there and  if any tablespace is  100% full, action the same

iii) Check the default trace for any critical errors

iv) Check application log to determine any memory related issues

v)  Check server node status at oslevel or through management console and 

     action and bring up the java again.

To estimate the user load and to check the number of users logged onto the java portal :

Navigate to User Administration ->  Activity Reports

i)   Check “Number of users in the last 3 hours” report

   ii)   To figure out most active users, check the 10Most active users report

Java Reports :

Java Memory Consumption report and Threads Reports :

These reports includes a chart of the memory usage of a cluster node and a chart related to the system and application thread pool.

To check this report login to nwa of the respective java stack 

Then  navigate to Monitoring -> Java System Reports :

Here following reports can be taken by selecting the respective report from the drop down

provided:

ü  Capacity Planning : This report includes a chart representing the requests sent to

 J2EE Engine, a chart for the number of http and security sessions, and a chart of the

 communication between J2EE nodes

ü  Resource Consumption : This report includes a chart of the memory usage of a cluster 

node, and a chart related to the system and application thread pool

ü  Error Statistics:  This report includes a chart representing a collection of counters

 useful for investigating problems. There are also charts that give an overview of

 timeouts and the size of log files

ü  Application Activities : This report includes a chart that represents the history of the

 activities of deployed applications

•        Slowest requests in detail
•        Slowest requests
•        Slowest components
•        User activities
•        Current activities
•        Monitor Browser

However from monitoring perspective, resource consumption report is most important to 

analyse the memory consumption.

Select resource consumption from the dropdown to view the memory statistics as below:

Click on Go to Detailed Chart link of the respective report to view detailed chart as below

Click Hint on charts link to analyse the report better.

Select the respective Instance, Cluster node and Time period from the provided drop down boxes to

 view the reports belonging to the same

Table view for Threads report:

There are 2 types of views: Chart view and Table view. You can change the view by selecting the respective radio button.

Please find below table view for Memory Consumption report

Session Monitoring:

To monitor sessions, navigate to Monitoring -> Session Monitoring
