CMSG_OC_MSGNO is an encoded field consisting of 4 bytes:
Byte 1 (the high-order byte) represents the Client-Library layer that is reporting the error. This byte is normally only used by Sybase Technical Support.
Byte 2 represents the message’s origin and is used internally by Sybase.
Byte 3 denotes the severity of the error. The following table describes the possible values.
Value |
Meaning |
|---|---|
CS_SV_INFORM (0) |
No error. The message is informational. |
CS_SV_API_FAIL (1) |
A Client-Library routine generated an error. This error is typically caused by a bad parameter or calling sequence. The server connection is probably salvageable. |
CS_SV_RETRY_FAIL (2) |
An operation failed, but it can be retried. |
CS_SV_RESOURCE_FAIL (3) |
Resource error. This error is typically caused by an allocation error, a lack of file descriptors, or a timeout error. The server connection is probably not salvageable. |
CS_SV_CONFIG_FAIL (4) |
Configuration error. |
CS_SV_COMM_FAIL (5) |
Unrecoverable error in the server communication channel. The server connection is not salvageable. |
CS_SV_INTERNAL_FAIL (6) |
Internal Client-Library error. |
CS_SV_FATAL (7) |
Serious error. All server connections are unusable. |
Byte 4 (the low-order byte) denotes the specific error detected by Client-Library.
