1. need to write a Pro*C multithreading daemon process
2. Username,pwd,sid, no.of threads values should read from a file.
3. multiple database connections will be opened based on the no.of threads.
4. No.of records should be shared across threads
5. Handling thread synchronization.
6. Need to select the data (name column) from emp table where status = 0
7. Need to implement the below mentioned if condition
If the name = “xxx” update the status = 1 in that table

evmd - Event Manager daemon SYNOPSIS
DESCRIPTION
The Event Manager (EVM) daemon, receives events from posting clients and distributes them to subscribing clients that have indicated that they are interested in receiving the events. The daemon is a critical system facility that is started automatically when the system tran- sitions to run level 2, and which should not be terminated. The daemon in turn starts the event logger, and the channel manager, On startup, the daemon reads its configuration file, the authorization file, and the event template files stored under the directory. If these files are modified while the daemon is running, the command must be used or a signal must be sent to instruct the daemon to reconfig- ure itself. The system administrator can control access to events by modifying the EVM authorization file, As a daemon, does not have a standard output. Any error messages are written to the file The EVM daemon is monitored by the Essential Services Monitor daemon, which automatically restarts if it terminates unexpectedly. See esmd(1M) for more information. RETURN VALUES
The following exit values are returned: Successful completion. An error occurred. WARNINGS
The daemon rejects any attempt by a posting client to post an event that has one or more of the following problems: o The event is not registered. o The event contains invalid item values. o The posting client is not authorized to post such an event. FILES
Default directory for event template files Default location for event filter files. Filter files must have the suffix Error log file for UNIX domain socket established for connection between the EVM daemon and the local clients Daemon process id saved by Lock file established to prevent multiple invocations of the daemon Default location of the EVM daemon configuration file Default location of the EVM daemon authorization file SEE ALSO
