The structure of message numbers
Message numbers have fourfold structure that consists of prefix, subcomponent identifier, number, and severity code.
- Prefix
- A three-character prefix that identifies the product or major component that issues a
message.
- BPO
- The Buffer Pool Analyzer program prefix.
- DGO
- Prefix that identifies workstation client messages.
- FPE
- The OMEGAMON for Db2 PE program prefix (components from former IBM® Db2 Performance Expert product).
- KDP
- The Tivoli® Enterprise Monitoring Agent (TEMA) for Db2 program prefix
- KO2
- The OMEGAMON for Db2 PE program prefix (components from the former OMEGAMON II product).
- Subcomponent identifier
- A one-character subcomponent identifier that identifies the subcomponent within a product
or major component. For example, in message FPEA1242I, the A identifies the Accounting
subcomponent in OMEGAMON for Db2
PE.
BPO messages use a single subcomponent identifier K, which means that all Buffer Pool Analyzer messages start with BPOK.
DGO messages use a single subcomponent identifier K, which means that all workstation client messages start with DGOK.
FPE messages use the following subcomponent identifiers:- A
- Accounting
- B
- User-Tailored Reporting (part of Batch feature)
- C
- Background control
- E
- Exception processing
- F
- Interactive Report Facility (part of Batch feature)
- I
- I/O activity
- J
- Installation and customization
- L
- Locking
- M
- Online Monitor
- R
- SQL activity
- S
- Statistics
- T
- Utility activity
- U
- Utility services
- V
- Data Server
- W
- System Parameters report set
- X
- Audit
- Y
- Explain
- Z
- Migrate/Convert function
KDP messages do not have explicit subcomponent identifiers.
KO2 messages use the following subcomponent identifiers:- A
- Reserved for Application Trace Facility (ATF)
- C
- Reserved for Interface, Cross-Memory, Display Module
- D
- Reserved for Data Analysis Module
- E
- Object Analysis
- H
- Near-Term History Data Collector
- I
- Reserved for D5API Framework
- M
- ISPF
- O
- VTAM® Display Logic
- P
- Reserved for D5API Collectors
- R
- Capture Server
- S
- Storage Manager
- T
- Reserved
- U
- Reserved for Utility I/O and Data Conversion Routines
- X
- Cross-Memory Module
- Z
- OMPE Subsystem
- Message number
- A unique number within the range of messages from a subcomponent.
- Severity
- An appending single-letter code that indicates the severity of the message.
- I
- Informational message that does not require any user action.
- W
- Warning message that should be analyzed to determine whether the condition can effect the results. Usually, a warning message does not prevent the system from execution.
- E
- Error message that can be corrected by an appropriate user action (for example, by correcting a command syntax error).
- S
- Severe error message that results from an abnormal condition and in the abandonment of processing for a command. Other commands in a job stream may still be executed.
- U
- Unrecoverable error message that results from an abnormal condition and in the abandonment of processing for the entire job. Most internal errors fall into this category.
