Configure E-mail For Oracle Enterprise manager DB 11gR2

Posted on by Osama Mustafa in Application
Sometimes you will be not be able to check the database out of the office, sick ….

Regarding to oracle documentation :-

The notification system allows you to notify Enterprise Manager administrators of alerts, policy violations, and the status changes of job executions. In addition to notifying administrators, the notification system can perform actions such as executing operating system commands (including scripts) and PL/SQL procedures when an alert is triggered.

Before Enterprise Manager can send e-mail notifications, you must first specify the Outgoing Mail (SMTP) servers to be used by the notification system. Once set, you can then define e-mail notifications for yourself or, if you have Super Administrator privileges, you can also define notifications for other Enterprise Manager administrators.

For More about E-Mail Notification Read here.

If everything is ready please follow the screen shot :-

TT6003: Lock request denied because of time-out

Posted on by Osama Mustafa in Database
Trying to create cache group lead to the below error :-

java.sql.SQLException: [TimesTen][TimesTen 11.2.1.4.0 ODBC Driver][TimesTen]TT6003: Lock request denied because of time-out
Details: Tran 143.23106 (pid 19946) wants Sn lock on rowid BMUFVUAAAAxogAALDp, table SUBSCRIBER. But tran 144.67398 (pid 19946) has it in Xn (request was Xn). Holder SQL (select ID,identifierType,identifiervalue,subscriberId,groupName,siid from subscriptionidentifie…) — file “tindex.c”, lineno 4277, procedure “sbTixNext()”

After check the Timesten parameter found the issue was with LockWait

Lockwait :- Allows an application to configure the lock wait interval for the connection.

LockWait may be set to any value between 0 and 1,000,000 inclusive to a precision of
tenths of a second. The default is 10 seconds.

Actual lock wait response time is imprecise and may be exceeded by up to one tenth of
a second, due to the scheduling of the agent that detects timeouts. This imprecision
does not apply to zero second timeouts, which are always reported immediately.

Cheers
