SAP Profile Parameters List

Below we have the SAP Profile Parameters list with default values and short description. The SAP parameters plays an important role starts with post installation activities, system configuration, memory management, logon security rules, internet security, port numbers configuration etc.

The SAP profile parameters can be configured in RZ10 transaction via profiles and some of the parameters in RZ11 transaction.

Note:

• Only the dynamic SAP parameters can be configured in RZ11 transaction, this will take effective with out system restart.
• All the static SAP parameters needs system restart to take effective.
• We can check whether the parameter is dynamic or static in RZ11 transaction by displaying the parameter, if the parameter have change option in RZ11 then we can consider it as dynamic parameter, if no change option then it is static.

Example: the Profile parameter rdisp/max_wprun_time is dynamic parameter.

Parameter Properties

You can use transaction RZ11 to display properties of profile parameters and to dynamically change the values of profile parameters. The properties of the profile parameter act as the basis for checking the default profiles and instance profiles in the system (transaction RZ10).

Metadata of Profile Parameters

Name: Name of Profile Parameter.

Parameter Type: Assignment of a profile parameter to a type. For each parameter type, there is a standard check. This check is always executed if there is no separate check function for the parameter.

The following types are currently defined:

1. Integer: This is an integral value. You can also specify a maximum and/or a minimum value.

Example:

rdisp/TRACE

Error situations:
a. Non-numerical values -> error
b. Larger than the maximum -> error
c. Smaller than the minimum -> error

2. Double: This is a floating point number. You can also specify a maximum and/or a minimum value.

Error situations:
a. Non-numerical values -> error
b. Larger than the maximum -> error
c. Smaller than the minimum -> error

3. Boolean: This is a switch with two statuses. Only the following values are permitted. All other values are interpreted as errors.

Example:

gw/keep_process

Permitted values: TRUE, FALSE, 0, 1, ON, OFF, YES, NO. The comparison is not case-sensitive.

4. Character String: This is any character string. No check is made.

Example:

abap/locale_ctype

5. Enumerations: These are enumerations. The parameter can only contain certain values.

Example:

rdisp/bufrefmode

Restrictions: The parameter type can be restricted further:

• Parameter type Integer to a range with a minimum value and a maximum value.
• Parameter type Double to a range with a minimum value and a maximum value.
• Parameter type Character String to a fixed number of parameter values that can be chosen. For example, “DIA BTC UPD UP2 SPO ENQ”.

Unit: A parameter value can have a unit. The following units are available:

• Bytes
• Kilobytes
• Megabytes
• Gigabytes
• Milliseconds
• Seconds
• Minutes
• Hours
• Days
• Percent

Parameter Group: The parameter group describes the application area in which the parameter is used. The following values are defined:

• System
• Dispatcher
• Internet Communication Manager (ICM)
• Enqueue
• Message Server
• ABAP
• Background Processing
• Perf
• Syslog
• Spool
• Database
• Alert
• J2EE Engine
• GUI

Parameter Description: Short description of the parameter. Is always written in English, since this text is not translated.

System-Wide Parameter: If the parameter has this property, the value of the parameter is fetched on each server during the check and the system checks whether the values are the same. The value must be the same on all servers.

Dynamic Parameter: If the parameter has this property, the value of the parameter can be changed dynamically, that is, during running operation. In this case, a “Change Value” button is automatically displayed in RZ11. If the user chooses the button, a dialog box appears, in which he or she can enter the new value for the parameter. In the dialog box, the user can check the “Switch on All Servers” field. This means that the value is changed on all servers of the system.

Changes are recorded both in the syslog as well as in the change history. The change history contains the last 10 changes and is deleted with every restart of the server.

In addition to the metadata, rz11 also displays information as to the source of the current parameter value. If the value has been changed manually, the source is displayed as “dynamic switch”, together with a link for calling the change history.

In some cases, the current value can deviate from the profile value, although it has not been changed manually. These cases are also viewed as dynamic changes. However, since there is no change history here, the comment “(kernel)” is displayed instead of a link to the change history. One example of a parameter where this effect can occur is rsdb/max_blocking_factor. If the profile value is -1, the parameter value will be changed by the kernel to the default value of the database interface (see SAP Note 1296224).

Vector Parameter: If the parameter has this property, the parameter can be set more than once in a vector. Example: icm/server_port can be configured as icm/server_port_0, icm/server_port_1, and so on.

Has Subparameters: If the parameter has this property, the parameter value consists of subparameters. Example: icm/ssl_config has the subparameters CRED, CACHESIZE, LIFETIME, VCLIENT, and CIPHERS.

Display the Current Values

• Kernel Default: Default value of the parameter, as defined in the SAP kernel.
• Default Profile: Default value of the parameter, as defined in the default profile DEFAULT.PFL.
• Instance Profile: Value of the parameter, as defined in the instance profile. If the parameter is not defined in the instance profile, the default value is used.
• Current Value: The value of the parameter as it is currently used in the system.
