>Description:
When Linux Informix-SE, any attempt to create a database will fail
with a Invalid argument error. Running truss(1) on the sqlexec process
reveals the following:
[...]
linux_open("a.dbs/syscolumns.idx",32770,00) = 4 (0x4)
linux_fcntl64(0x4,0x2,0x1) = 0 (0x0)
linux_open("a.dbs/syscolumns.dat",32770,00) = 5 (0x5)
linux_fcntl64(0x5,0x2,0x1) = 0 (0x0)
linux_fcntl64(0x4,0xe,0x8193a88) ERR#22 'Invalid argument'
write(1,0x81a4500,22) = 22 (0x16)
[...]
A quick look at a Linux system's /usr/include/bits/fcntl.h shows:
[...]
/* Values for the second argument to `fcntl'. */
#define F_DUPFD 0 /* Duplicate file descriptor. */
#define F_GETFD 1 /* Get file descriptor flags. */
#define F_SETFD 2 /* Set file descriptor flags. */
#define F_GETFL 3 /* Get file status flags. */
#define F_SETFL 4 /* Set file status flags. */
#ifndef __USE_FILE_OFFSET64
# define F_GETLK 5 /* Get record locking info. */
# define F_SETLK 6 /* Set record locking info (non-blocking). */
# define F_SETLKW 7 /* Set record locking info (blocking). */
#else
# define F_GETLK F_GETLK64 /* Get record locking info. */
# define F_SETLK F_SETLK64 /* Set record locking info (non-blocking).*/
# define F_SETLKW F_SETLKW64 /* Set record locking info (blocking). */
#endif
#define F_GETLK64 12 /* Get record locking info. */
#define F_SETLK64 13 /* Set record locking info (non-blocking). */
#define F_SETLKW64 14 /* Set record locking info (blocking). */
[...]
I'm assuming that the '0xe' in the invalid call above refers to
F_SETLKW64 on the Linux side. Any tips to fix this appreciated.
