MQSeries.net :: View topic - Cleaning IPC resources for a specific Queue Manager

jpiette

We are running MQSeries 5.1 in a Compaq Tru64 environment ( Compaq Tru64 UNIX V5.1A ). I'm looking for something that will allow me to clean up IPC resources for a specific queue manager. At time we have been forced to kill a runaway queue manager, but because we are running multiple queue managers it make it impossible to clean up the IPC resources properly. I was given a piece of code that performs this function in an AIX environment, but I have not been able to get it to work in the Tru64 environment. The code is as follows:

main(int argc, char *argv[])
{
key_t Key;
FILE *fp;
char buf[101];

if (argc < 2)
{
printf("%s: Please specify filename\n",argv[0]);
exit(1);
}

if ((fp = fopen(argv[1],"r")) == (FILE *)NULL)
{
printf("Cannot open %s!\n",argv[1]);
exit(2);
}

memset ( buf , NULL , sizeof ( buf ) ) ;
while (fgets(buf,100,fp) != NULL)
{
buf[strlen(buf)-1] = '\0';
Key = ftok(buf,'S');
if ( errno > 0 )
{
printf ("Error returned from FTOK was %s - file %s\n", strerror(errno) , buf ) ;
}
else
{
printf("file %s S key 0x%08x\n",buf,Key);
}
Key = ftok(buf,'M');
if ( errno > 0 )
{
printf ("Error returned from FTOK was %s - file %s\n", strerror(errno) , buf ) ;
}
else
{
printf("file %s M key 0x%08x\n",buf,Key);
}
memset ( buf , NULL , sizeof ( buf ) ) ;
}

fclose(fp);

exit(0);
}

What is being passed into the function is a file containing a complete list of all files under the /var/mqm directory. The KEY generated by the code does not match the KEY for the mq IPC resources.

Any one have anything that might help?? Thanks.
