Hello,
I am new to this forum and this is my first post here...
I have never worked on either Pro*C or Multithreading..Now, i have to write a Pro*C, Multithreading daemon process.. I dont know where to start.. Can anybody help me with examples?
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
Else
Update the status = 2 in that table
Commit;

cgrulesengd
CGRULESENGD(8) libcgroup Manual CGRULESENGD(8) NAME
cgrulesengd - control group rules daemon SYNOPSIS
cgrulesengd [options] DESCRIPTION
cgrulesengd is a daemon, which distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group. The list of rules is read during the daemon startup is are cached in the daemon's memory. The daemon reloads the list of rules when it receives SIGUSR2 signal. The daemon opens a standard unix socket to receive 'sticky' requests from cgexec. OPTIONS
-h|--help Display help. -f <path>|--logfile=<path> Write log messages to the given log file. When '-' is used as <path>, log messages are written to the standard output. If '-f' and '-s' are used together, the logs are sent to both destinations. -s[facility]|--syslog=[facility] Write log messages to syslog. The default facility is DAEMON. If '-f' and '-s' are used together, the logs are sent to both destina- tions. -n|--nodaemon Don't fork the daemon, stay in the foreground. -v|--verbose Display more log messages. This option can be used twice to enable more verbose log messages. -q|--quiet Display less log messages. This option can be used twice to enable even less log messages and to only log errors. -Q|--nolog Disable logging. -d|--debug Equivalent to '-nvvf -', i.e. don't fork the daemon, display all log messages and write them to the standard output. -u <user>|--socket-user=<user> -g <group>|--socket-group=<group> Set the owner of cgrulesengd socket. Assumes that cgexec runs with proper suid permissions so it can write to the socket when cgexec --sticky is used. FILES
