[Linux-abi-devel] Interactive Unix 3.2 Oracle 6 under Linux-ABI hangs.

[Olaf K. <ok...@ad...>]

Hello, 

I have the need to run a very old Oracle 6 for Interactive Unix 3.2 under
Linux. I compiled the 2.4.18 patches and am able to run all the Interactive
Unix commands. But when i try to start the oracle db within "sqldba" with
"startup", the command hangs. I already inserted some printk() and got some
weirdness with semaphores: 

oracle creates a semaphore:
Sep  4 15:49:36 n24 kernel: [oracle:439]: semsys(1, 0, 40, 0x3a0)
Sep  4 15:49:36 n24 kernel: svr4_semsys: 0, 40, 928
Sep  4 15:49:36 n24 kernel: [oracle:439]: semget(0, 40, 1640)
Sep  4 15:49:36 n24 kernel: [oracle:439]: semsys returns 163840 (edx:95) 

the pmon tries to get the semaphore:
Sep  4 15:49:36 n24 kernel: [oracle:440]: semsys(2, 163840, -1073745302, 
0x1)
Sep  4 15:49:36 n24 kernel: svr4_semsys: 163840, -1073745302, 1
Sep  4 15:49:36 n24 kernel: svr1_semop - Args: 163840, (1, -1, 0), 1
Sep  4 15:49:36 n24 kernel: svr1_semop - semval: 0
Sep  4 15:49:36 n24 kernel: [oracle:440]: semop(1, -1, 00) 

after that the processes hang. The semop() manpage describes excatly
this behavour - but I dont know why the process does this semop()
call all the time - I even wrote a little program to set the semval,
and after setting it to 10000, the oracle process called the semop()
function until semval was 0 again. 

Any hints or tried someone this before me? 

Bye, Olaf
