I'm running a weblogic server on solarix x86 - 64bit with the command line: -Xrs -Xms4096m -Xmx4096m -XX:MaxPermSize=256m -da ... so the max heap size should be 4G, however after a night, it crashed and generated a 39G core: -bash-3.00$ ls -l core -rw------- 1 user group 39017429722 Sep 27 19:47 core I used pmap to dump the c...
At work we have several Solaris servers. Each server runs apache which we compiled a few years ago. It's been fine so far. Now we want to build one apache, using the latest version, and have it include LDAP authentication modules (for AD integration), NTML authentication and mod_perl. I can't find a guide for building apache like this ...

Every now and then I use the mdb debugger to examine core dumps on Solaris. One nice article that I looked at to get up to speed on the possibilities with mdb is http://blogs.sun.com/ace/entry/mdb_an_introduction_drilling_sigsegv where the author performs a step-by-step examination of a SIGSEGV crash. In the article the author uses "walk...

How can we debug Solaris 10 (Sparc) device drivers like we debug user processes using gdb? ...
On my Solaris 10 update 9 system the following command yields: #isainfo -b 64 But if I create the following program in C with limits.h is included I get: #include <stdio.h> #include <limits.h> int main(void) { printf("Maximum integer value on this system is = %d\n", INT_MAX); } gcc on64.c -o on64 ./on64 Maximum integer va...
I wrote a test program like this: #include <sys/socket.h> int main( void ) { int sock = socket(AF_INET, SOCK_DGRAM, 0); return 0; } And tried to compile it: $ /tool/sunstudio/bin/cc test.c Undefined first referenced symbol in file socket test.o l...

Whenever we set one of them...
Hello! I have oracle database on the Solaris 9 box Oracle datafiles stored on the ufs filesystem mounted with forcedirectio . So I'm using now only Oracle Buffer Cache question: is it good idea to remove forcedirectio option to improve IO performance? ...
Hello all! I'm migrating a multi threaded application from HP-UX to Solaris and so far, everything is OK except for one thing! The application has a thread that is handling the signals and, when some of them are received, it runs some cleaning (logging, kill child processes and so on). I've reduced the code as much as it was possible t...
I have to make a ioctl call to the 64 bit driver code from a 32 bit application. I have send a structure as an argument to ioctl call. I see lot of alignment and padding issues because of difference in architecture of user and driver code. Is there any way to solve this structure and padding created due to difference in architecture of u...

Is there any way to the get the name of the opened device file in driver's open call. or Is there any way to get the name of the devic...
I want a similar function similar to the VC++ GetThreadTimes function to work on solaris. I need a monitoring tool to monitor thread and monitor execution time from another thread. Is there a direct way of doing this? I have found that getrusage() can do this only to get the value of times() for the calling thread. But I what I want to...
In my program, I create 100 threads, then wait for all of them to join and then repeat this operation again. In each of the threads, I create some memory and free it. I am fairly sure, all the memory which I am creating in those threads are getting freed. But, the SIZE output and RSS output of prstat are continously increasing. They ar...
