Transcript

  • 1. Logon Load Balancing (SMLG) - SAP....Go to transaction code SMLG and create Logon Group and do assignments of theinstances as required by you...Users workstation services file requires an entry defining the serviceport ofthe new logon group. (ex. sapmsSID 3602)where SID is your system ID. Port # can change, I believe the default is 3600.User uses groups button on SAP GUI to create new logon pad entry.Enter SIDand message server hostname.Click generate list and thelogon group you defined should appear in the whitebox below. Choosethe correct group and click button add and logon. Usuallyno AProuter string is required (depending on your network setup).Logon groups appear with a different icon (in the SAP Logon Pad list)than singleserver logons. Single servers show a little orange manbeside an SAP logo, logongroups show 3 boxes (supposed to representservers I guess) close together.If you create multiple logon groups to segregate users by user group(ex. FIusers in FI_GROUP and SD users in SD_GROUP), then you adjust thedesktopsettings (as above) accordingly.==========================Check in DEFAULT profile rdisp/mshostYou need enter this servers I.P address in the group selection --> messageserver i.pYou need to add the service port sapmsSID 3600/tcp in services file..(you may need to give an additional ENTER after this entry else it doesnt workat times :) )
  • 2. If it still doesnt work, create a file sapmsg.ini inc:windows or c:winnt for the presentation machine and add the followingentry[Message Server]SID= I.P address of message server======================You need to define the sapms in the windows services files locatedunder "C:WindowsSystem32" or "C:WindowsSystem32driversetc" (WinXP)Add the line at the end of the filesapmsSID port number of the message server/tcpExamplesapmsPRD 3602/tcpConfiguring Logon GroupsUseIn SAP Logon, you can create and delete group entries, remove instances from groups, and delete entirelogon groups. When you call transaction SMLG, the CCMS: Maintain Logon Groups screen shows a table with entries for logon groups and the associated instances. An entry in this table, which is characterized by an instance and a logon group, is known as as assignment. A logon group to which multiple instances belong therefore consists of multiple assignments in this table, where an assignment contains one instance in each case.ProcedureCreating a Logon Group or Adding an Instance to a Logon Group... 1. Choose CCMS Configuration Logon Groups, or call transaction SMLG.
  • 3. 2. Choose (Create Assignment), and specify the desired name of the logon group in the Logon Group input field. Enter the name of the desired Instance that is to belong to the logon group. The logon group SPACE is reserved for SAP; therefore, do not use this name. 3. Repeat the last step until you have entered all instances that are to belong to the logon group. 4. Save your changes.Deleting a Logon Group or Removing an Instance from a Logon Group... 1. Choose CCMS Configuration Logon Groups, or call transaction SMLG. 2. Select any assignment for the logon group that you want to delete or from which you want to remove an instance. 3. To remove an instance from the selected logon group, choose Remove Instance, enter the desired instance on the next screen, and confirm your choice by choosing (Delete). 4. To delete the desired logon group, choose Delete Group and confirm your choice by choosing (Delete) on the next screen. 5. Save your changes.Changing Properties of an Assignment, a Logon Group, or an Instance... 1. Choose CCMS Configuration Logon Groups, or call transaction SMLG. 2. To change the properties of an assignment, double-click the assignment, and switch to the Properties tab page. 3. You can change the following properties: ○ IP address of the application server Only enter a value in this field if the application server associated with the instance needs to be addressed by the front end with a different IP address to the one used for application server-internal communication. This value applies only for the selected assignment. ○ Settings for external RFC call You can use this indicator to determine whether logon using an external RFC connection is to be permitted. This value applies to the selected logon group. ○ Threshold values for dialog response time and number of users logged on If you log on using a logon group, the logon is automatically performed using the instance of the group that currently has the best dialog quality. This quality is a key figure that is calculated from the number of users logged on and the average dialog response time. To allow the different prerequisites of different instance to be taken into account in this calculation, you can set threshold values for the dialog response time and the number of users yourself. The larger the actual values for response time and the number of users are in comparison to the threshold values set, the lower the quality. These figures apply for the selected instance. The values for Response Time and Users are not absolute limits, but rather thresholds. Even if the current value for response time or number of users is higher than this threshold value, it is possible to log on to another instance. The threshold values only influence the calculation of the current logon server of the logon groups.
  • 4. You can use a preview to see how the settings of the threshold values can affect the quality calculation, based on the current performance data. Choose Test to do this. In a logon group, the instance with the highest quality key figure is always selected for the logon.4. Choose Copy, and save your changes.
