System Administration Assistant

This section introduces other general system monitoring tools, mainly from the Basis point of view. These tools come bundled in an SAP function called System Administration Assistant, which is accessible via transaction SSAA. SSAA contains SAP-recommended daily, weekly, monthly, nonscheduled, and occasional system monitoring tasks. The following procedure demonstrates the use of this function.

Work Instructions

Step 1. Run transaction SSAA. Click graphics/question1.gif to get basic ideas about what this tool is and how it works.

Step 2. The opened Application help file indicates that SSAA is System Administration Assistant, an administration concept implemented by SAP for system administrators.

Result

We can now start the SAP-recommended daily, weekly, monthly, nonscheduled, and occasional system monitoring tasks.

We can also perform these tasks directly by running their corresponding transaction codes and UNIX commands (see Table 13.2).

Note

CCMS stands for Computer Center Management System. As shown in Screen 13.22, CCMS itself collects together many monitoring tasks.

Each monitoring task in Screen 13.21 has three icons. Table 13.3 describes how to use these icons.

Table 13.3. FUNCTION ICONS IN SCREEN 13.21

Name Icon Meaning
Documentation graphics/documentation.gif Click this icon to open a help file about this monitoring task.
Execute graphics/clock.gif Click this icon to start the monitoring task.
Status graphics/status.gif The task has not been started. This icon will change to graphics/newicon.gif after you click graphics/clock.gif, even though the task has not finished yet.

For example, if we click graphics/clock.gif next to SAP: CCMS System Monitoring (General Monitoring Functions) in Screen 13.21, we get another SAP session (Screen 13.23).

From this screen, we can monitor the following items:

  • Background Processing, which includes background work processes and background jobs.
  • Buffers, which include memory buffers for SAP objects, such as programs, table definitions, and table entries.
  • Change and Transport System, which includes the object export/import and transport environment.
  • Communications, which include gateway services, ALE (Application Link Enabling), and transactional RFC (Remote Function Call). BEx requires gateway services to communicate with an SAP application server. BW requires ALE and transactional RFC to communicate with its R/3 source systems.
  • Data Archiving, which was introduced in BW 3.0A and is not available in 2.0B.
  • Database, which includes space, performance, and backup/restore operations.
  • Dialog Overview, which includes dialog response time and network time.
  • Entire System, which duplicates other functions listed here.
  • Operating System, which includes the file systems, CPU, paging, swap space, and LAN.
  • Security, which includes security checks and audit logs of CPI-C (Common Programming Interface – Communications) and RFC logons.
  • Spool System, which includes spool work processes and the spool queue length.
  • System Log.

Now that we know how to monitor a BW system and measure its performance, we can examine techniques to improve query performance and load performance.
