We can display the cause of an error that we received and troubleshooting suggestions, with the OERR Utility.<\/p>\n

It is located under the $ORACLE_HOME\/bin directory. We can use the OERR utility after setting the variables.<\/p>\n

If you are not familiar with the error, OERR can quickly provide information on identifying the problem.<\/p>\n

-bash-4.3$ . oraenv\nORACLE_SID = [oracle] ? TESTDB1\nThe Oracle base remains unchanged with value \/u01\/app\/oracle\n-bash-4.3$ oerr\nUsage: oerr facility error\n\nFacility is identified by the prefix string in the error message.\nFor example, if you get ORA-7300, \"ora\" is the facility and \"7300\"\nis the error. So you should type \"oerr ora 7300\".\n\nIf you get LCD-111, type \"oerr lcd 111\", and so on.<\/pre>\n
The use is as follows:<\/h3>\n
For ORA-03113 error;<\/strong><\/p>\n
-bash-4.3$ oerr ora 3113\n03113, 00000, \"end-of-file on communication channel\"\n\/\/ *Cause: The connection between Client and Server process was broken.\n\/\/ *Action: There was a communication error that requires further investigation.\n\/\/ First, check for network problems and review the SQL*Net setup. \n\/\/ Also, look in the alert.log file for any errors. Finally, test to \n\/\/ see whether the server process is dead and whether a trace file\n\/\/ was generated at failure time.<\/pre>\n
For ORA-01555 error;<\/strong><\/p>\n
-bash-4.3$ oerr ora 1555\n01555, 00000, \"snapshot too old: rollback segment number %s with name \\\"%s\\\" too small\"\n\/\/ *Cause: rollback records needed by a reader for consistent read are\n\/\/ overwritten by other writers\n\/\/ *Action: If in Automatic Undo Management mode, increase undo_retention\n\/\/ setting. Otherwise, use larger rollback segments<\/pre>\n
For RMAN-01009 error;<\/strong><\/p>\n
-bash-4.3$ oerr rman 01009\n1009, 1, \"syntax error: found \\\"%s\\\": expecting one of: \\\"%s\\\"\"\n\/\/ *Cause: A syntax error was signaled during parsing.\n\/\/ *Action: Correct the input.<\/pre>\n
For CRS-00215 error;<\/strong><\/p>\n
-bash-4.3$ oerr crs 215 \n215, 1, \"Could not start resource '%s'.\"\n\/\/ *Cause: There was an internal error while starting the resource.\n\/\/ *Action: Check the CRS daemon log file.<\/pre>\n\n
