Oracle ORA00058 Error Analysis and Solutions（oracle00058）

Oracle ORA-00058 Error is a generic error code which means “too many ORACLE error has occurred”. It usually happens when too many connections are made at the same time or when too many users try to perform queries on the system. This error usually occurs in the subclient resources within an Oracle database.

The analysis of this error can be done with simple debugging techniques, like checking the log file to find out which query or user caused the problem. It should be noted that if the query is complex, it might cause the Oracle server to experience a heavy workload, leading to the ORA-00058 error.

The main reason for the ORA-00058 error is either excessive memory usage or too many open database connections. To analyze the root cause and solve the problem, the first step is to identify how many database connections exist. This can be done using the “show database connections” command.

Next, any connections that are idle need to be closed. This can be done using the “Kill connection” command or the “ALTER SYSTEM” command to terminate the connection and close it. If the ORA-00058 error still persists, the user should look into their database configuration. They may need to increase the database size, or if the database is already large enough, they may need to change the number of connections allowed.

Finally, if the ORA-00058 error still persists, then the user should check the database’s log files to identify if any queries or users are causing the problem. Once the cause is identified, the user can take necessary steps to fix it and should no longer experience the ORA-00058 error.

To summarize, Oracle ORA-00058 error can be caused by either excessive memory usage or too many open database connections occurring at the same time. To analyze and solve the problem, the user should first identify how many database connections exist and close any idle connections. If the error persists, the user should then look into their database configuration and check its log files for any queries or users causing the problem. By following these steps, the user should be able to solve the ORA-00058 error and prevent it from occurring in the future.
