Licensed Internal Code (LIC) Log and VLOG Primer

Troubleshooting


Problem

This document provides basic information about LIC log and VLOG.

Resolving The Problem

This document describes how to display Licensed Internal Code (LIC) logs and how to identify the common components of VLOGs. LIC logs are also known as VLOGs. Not all LIC Logs indicate an error or a problem; however, they can describe an informational condition.

LIC Logs are usually described as a combination of their Major and Minor codes, for example, major code 1000 and minor code DDDD. However, searching for APARs and PMRs requires a LIC Log prefix of VL. For example, the documentation for this major/minor code is: VL1000DDDD.

Viewing LIC Logs

To view the LIC logs, do the following:

1.On the operating system command line, type the following:

STRSST

Press the Enter key.
2.Sign on SST with the QSECOFR or 22222222 profile and the corresponding password.
3.From the SST main menu, select Option 1, Start a Service Tool.
4.Select Option 5, Licensed Internal Code log.
5.Select Option 1, Select entries from the Licensed Internal Code (LIC) log.
6.At the screen titled Specify Licensed Internal Code Log Selection Values, pressing the Enter key will display the most recent VLOG entries. However, VLOGs can also be displayed by date range, type, or entry ID.

Identifying Components

Each VLOG will have the same identifying components:

Entry ID:
Each VLOG has a unique eight character entry identifier, which ranges from 00000000 to FFFFFFFF. By searching on 00000000 for the ID, the oldest VLOGs will be displayed. The default of FFFFFFFF will display the most recent VLOGs. Some QSYSOPR messages will mention an eight character log ID, which is different from the eight character Major and Minor code combination.

Major Description:
Every Major Description corresponds with a Major Code. In the above example, every Major Description of 'IPL' is a Major Code of 0500. Conversely, every 0500 VLOG is an IPL VLOG.

Major Code:
A four character identifier for each type of VLOG. In the above example, every 0200 Major Code VLOG is a Function Check VLOG. Searching on just the Major Code will display only those types of VLOGs.

Minor Code:
A four character value that corresponds to its Major Code. Not every Major Code will have a variety of Minor Codes. For example, 0600 Database VLOGs tend to have several different Minor Codes. However, 0500 IPL VLOGs can have just a few possible Minor Codes. If searching by Minor Code, a valid Major Code must also be specified.

Date and Time:
There will be times that no VLOGs are written, depending upon what the system is doing. At other times, a lot of VLOGs can be logged. VLOGs can be searched by their date and time, especially if the Major Code or Entry ID are not known.
