Oracle Error Information Utility oerr

You can look up the explanation of Oracle error code on the database server itself using oerr utility on UNIX OS. Here is an example explanation of ORA-1555 error.

sapadm> oerr ora 1555
01555, 00000, "snapshot too old: rollback segment number %s with name \"%s\" too small"
// *Cause: rollback records needed by a reader for consistent read are
//         overwritten by other writers
// *Action: If in Automatic Undo Management mode, increase undo_retention
//          setting. Otherwise, use larger rollback segments

Pretty handy if you are working for a third-class company that blocks google search.
