System value parameters

You can set or view system values in IBM® Navigator for i. However, if you want to code a program to set or retrieve a system value, you need to use the character-based system value name and its associated special parameters.

The character-based system value name corresponds to a system value field in IBM Navigator for i and the character-based special parameter corresponds to a possible value in IBM Navigator for i.

The following table provides a complete list of system values (using the character-based names) and their associated special parameters. The table provides a summary of information that you might need to work with the system value in the character-based interface. The types and lengths specified in this table apply to CL commands. This differs from the Retrieve System Values (QWCRSVAL) API, which uses binary types rather than decimal types. For example, the Retrieve System Value (RTVSYSVAL) command expects decimal types while the Retrieve System Values (QWCRSVAL) API returns binary types.

If you are familiar with the IBM Navigator for i name (also referred to as a field on the IBM Navigator for i interface) and cannot find the character-based system value name in the following table, use the System value finder to display a category of system values. Each category identifies the IBM Navigator for i system value names and the character-based names.

Note: For optimal printing of the list of system values in this topic, you need to print it from a Web browser. To print this topic from a Web browser, select File > Print. Ensure that the paper orientation is landscape.

The following table identifies all of the system values using their character-based names and the character-based parameter values (Possible values column) for each system value.

Notes: 1 In IBM Navigator for i, this system value is grouped with other character-based system values. Therefore, the topic specific to this system value discusses all of the system values associated with it in IBM Navigator for i. For example, the QTIME system value is called Time of day in IBM Navigator for i and it uses QTIME, QDATETIME, QHOUR, QMINUTE, and QSECOND. 2 The operating system no longer uses this system value. 3 In IBM Navigator for i, the Maximum system disk pool usage (QSTGLOWLMT) system value is the maximum percentage of used storage allowed. In the character-based interface, this system value specifies the disk pool lower limit versus the maximum allowed.
