SQL error states
When the JDBC driver that you are using does not indicate a valid SQL error state for an error, the gateway will make the best effort it can to recover.
In cases where the gateway cannot recover from such an error, data will be discarded and lost. The following is an example of an error that is logged when the gateway cannot determine a valid SQL error state:
11/26/10 14:28:20: Error: E-GJA-000-000: [ngjava]: G_JDBC:
pool-1-thread-2: SQL State is null
