Using the Logs Generated by the TimesTen Daemon

The TimesTen daemon and its subdaemons and agents generate error, warning, and informational messages. These messages may be useful for TimesTen system administration and for debugging applications.

By default, informational messages are stored in:

  • A user error log that contains information you may need to be aware of, including actions you may need to take.

  • A support log containing everything in the user error log plus information for use by TimesTen Customer Support.

See Error, Warning, and Informational Messages in the Oracle TimesTen In-Memory Database Operations Guide for information about configuring the logs, including their location and size.

All message categories are enabled by default, but you can also disable or explicitly enable the following categories of user error log messages for all databases or specified databases through options of the ttDaemonLog utility:

  • ALL (default): For all messages

  • CACHE: For messages from the cache agent, designated by CAC

  • DAEMON: For messages from the main daemon and subdaemons

  • DAEMONDBG: For additional information from the main daemon and subdaemons.

  • REPLICATION: For messages from the replication agent, designated by REP

  • SERVER: For messages from TimesTen Server.

See ttDaemonLog in Oracle TimesTen In-Memory Database Reference for information about ttDaemonLog options.

This message is caused by the failure of the system call chdir. Ensure that you have installed TimesTen properly and the directory exists. Consult your system documentation to determine the cause of this error.

10

Server is exiting. Could not connect to TimesTen daemon. Check to make sure that the TimesTen daemon/service is running

The TimesTen server communicates with TimesTen Data Manager daemon. Ensure that TimesTen Data Manager daemon/service is running.

11

Main Server cleaned up all child processes and exiting.

ServerProc thread of the TimesTen server accepts all connection requests from a TimesTen client. A log entry with EventID=99 just prior to this may contain additional information. Consult your system documentation to determine the cause of this error.

12

Server is exiting. Failed to create shared memory segment for IPC. Error_message

This message is caused by the failure to create a shared memory segment for IPC. A log entry with EventID=99 just prior to this may contain additional information. Consult your system documentation to determine the cause of this error. This message is generated only for a connection that uses a shared memory segment as the IPC mechanism.

13

Server is exiting. Failed to attach to shared memory segment for IPC. Error_message

This message is caused by the failure to attach to a shared memory segment for IPC. A log entry with EventID=99 just prior to this may contain additional information. Consult your system documentation to determine the cause of this error. This message is generated only for a connection that uses a shared memory segment as the IPC mechanism.

14

Server is exiting. Failed to create semaphore for IPC. Error_message

This message is caused by the failure of a semaphore creation. A log entry with EventID=99 just prior to this may contain additional information. Consult your system documentation to determine the cause of this error. This message is generated only when the TimesTen server is configured to allow shared memory segment as IPC.

15

Client application terminated. Terminating corresponding TimesTen child server process

This message implies that the TimesTen server has lost a TCP/IP socket connection to the TimesTen client ODBC driver (and hence the application) before the application closed the ODBC connection properly. This can happen only if the client application (or the thread that had the ODBC connection) exited without closing the ODBC connection. This message is generated only for a connection that uses a shared memory segment as the IPC mechanism.

16

Connect succeeded from client: client_host_name(client_domain_name); IP Address: client_IP; Client PID: client_PID; DSN: server_DSN; UID: client_UID

This message is informational only. Could be used to match the connects and disconnects by a TimesTen client application to/from a TimesTen server.

17

Connect failed for client: client_host_name(client_domain_name); IP Address: client_IP; Client PID: client_PID; DSN: server_DSN; UID: client_UID; SQL State: SQL_state; Error: error_message

This error is generated if SQLDriverConnect fails. The runtime error returned by the driver may indicate the cause of the error. The corrective action depends on the runtime error. For details, refer to the Microsoft ODBC API Reference at https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/odbc-api-reference.

18

Server is exiting. Failed to create REQUEST semaphore for IPC. Error_message

TimesTen uses a pair of semaphores called REQUEST and RESPONSE to implement shared memory segment as IPC. This message is caused by the failure of a REQUEST semaphore creation.

This message is generated only when the TimesTen server is configured to allow shared memory segment as IPC.

19

Server is exiting. Failed to create RESPONSE semaphore for IPC. Error_message

TimesTen uses a pair of semaphores called REQUEST and RESPONSE to implement shared memory segment as IPC. This message is caused by the failure of a RESPONSE semaphore creation. A log entry with EventID=99 just prior to this may contain additional information. Consult your system documentation to determine the cause of this error. This message is generated only when the TimesTen server is configured to allow shared memory segment as IPC.

20

Shared memory segment for IPC exhausted the configured maximum. File: source_file_name; line: line_number; size: requested_size

There is not enough space left in the configured shared memory segment for IPC. This message generated only for a connection that uses a shared memory segment as the IPC mechanism.

21

Server is exiting. Failed to open shared memory segment for IPC. Error_message

This message is caused by the failure to create a shared memory segment for IPC. A log entry with EventID=99 just prior to this may contain additional information.
