Message descriptions
For each message that is described in this section, the following items of information are described:
Note: When a message variable is to be replaced with text, such as
the name of a column in a Db2® table
that is not in U.S. English, it may not always be possible to display
the variable text. This is likely the case when messages are routed
to the system console or a spool data set, such as CHCPRINT or CHCAUDIT,
which generally can only display single-byte EBCDIC characters. In
these cases, the variable text will be translated to EBCDIC for display.
If the variable text contains untranslatable characters, then the
untranslatable characters will be replaced with a placeholder ('*')
in the message as it appears on the console or in the sysprint data
set. For logged messages, the full untranslated text is recorded in
the Product Administration Log, and can normally be viewed with Management Console.
- Message Identifier and Text—The first item of information that is provided is the actual message identifier and text that appears in the system or product administration logs. In some messages, brace brackets in the text identify a finite set of terms (terms are separated by vertical bars). Only one of the terms that are listed actually appears in the message text. If the list of possible terms is long, the message text contains a numeric reference to a list of the terms presented below the message text.
- Explanation—Explains the message in more detail and describes the possible causes that led to the message being generated.
- Message Variable—Identifies and describes each variable that is part of the message text. Variables are presented in italic text in the message. They are used to focus attention on specific items (for example, a specific table or subscription that needs to be identified). As a result, a variable can have an unlimited number of values (names, numbers, and so on). Note that some messages do not contain variables.
- Message Destination—Identifies
where the message is logged. Most messages are routed to either the
system or product administration log.
- System log (SYSLOG)— A z/OS® log that InfoSphere® CDC uses to convey information about product operations to the console operator. Note that system log messages may or may not be directed to the operator console.
- Product administration log— An InfoSphere CDC log (in the CHCPRINT spool data set) containing messages that you can read in Management Console.
Some messages may only be displayed interactively, in a message box, in Management Console and not placed in the product administration log. InfoSphere CDC also maintains a log (in the CHCAUDIT spool data set) that is intended for diagnostic purposes. Some messages are just placed in this log. The destination for these messages is identified as the audit log.
- System Action—If applicable, the action that is performed or not performed by the system in situations that led to the message being generated.
- Operator Response—If applicable, the actions that should be taken by the console operator in response to the message. When the console operator is required to act, it is usually in response to a message that is placed in the system log.
- Client Administrator Response—If applicable, the actions that should be taken by the client administrator in response to the message. In this section, the client administrator refers to the person responsible for configuring replication in Management Console. When the client administrator is required to act, it is usually in response to a message that is placed in the product administration log.
