Re: instance shutdown problem ? (please help)
John, Well, system does not do a shutdown abort. Oracle finds a problem and then instance aborts. A few things you can do here. (1) See if a trace file is generated around that time in user_dump_dest or background_dump_dest that might provide clues. If you see a core fiel in any directory named core_* in the core_dump_dest, it has cored dumped. (2) Start the database from command line. From NT services panel, make the services OracleServiceXXX manual, from automatic. Then reboot the box. Start the service manually and then see what happens in the process. (3) Start the instance and service in a command prompt window using oradim comamnd. I am not sure of the options; but the oradim command gives a help. At some point you would hit a problem that is decipherable. Please let us know what came out of it.

RE: 1M STRIPE SIZE BEST?
Jared, If an I/O call size is bigger than the Striping Unit (the size of one chunk), then a single I/O call can motivate participation of 2+ disks in an array. Even if the I/O call size is exactly the same as the striping unit, it can still motivate activity on 2 disks under normal operating conditions. See Hank Tullis's explanation at www.hotsos.com/catalog. Of course, under partial outage conditions, any read to the failed disk and any write to any disk in the array will engage participation from all the living disks in the array.

Re: Do user processes apply against shmmax limit?
Tim, Unless shared servers (MTS) are in use, in which case either the UGA or PGA is in the SGA. To be honest, I can't recall which, and I'm too lazy to go look it up right now. But MTS will consume memory on a per user basis, though the poster didn't mention it. And I'm quite sure you know this, but thought I would mention for the benefit of those on the list that don't know that. Let one of them look it up. :) Also, the vmstat stats show PI/PO at very low rates, and the SR ( scan rate ) is mostly zero. Jay, Ask your SA "Where's the memory problem?"

Re: 1M STRIPE SIZE BEST?
Maybe I've forgotten something fundamental about the way RAID 5 works, I dunno. But I'm having a hard time understanding how stripe size is going to determine the number of heads used in an IO. RAID 5 distributes the data across all spindles, with 1 or more of the spindles for any IO being used for the parity data. Someone care to enlighten me?

Re: Storing of number datatype in table
There is a file called glogin.sql under $ORACLE_HOME/sqlplus/admin where you
can place the line set numwidth 13, or whatever else. This file is read by
every session when they connect through sql*plus in that machine. Caution :
sessions sonncting through sqlplus only on that machine read this, not from
other cleint machines.

Do user processes apply against shmmax limit?
Hi everyone, I was always under the impression that the only concern with shmmax was that it be large enough for the SGA to fit into it. One of my System Administrators has just told me that the individual user processes (i.e., the PGA since we're not using multi-threaded server) get added to the SGA and if that SGA + user processes > shmmax the system will start swapping. I haven't found anything to specifically address this issue on Metalink so I though I'd throw it open. We've started experiencing system slowdown and he says that increasing shmmax could resolve it. I'm skeptical (he also suggested increasing SGA to decrease swapping which I told him in no uncertain terms was nonsense). If anyone has a link to a note or white paper I'd appreciate that too. I've appended his email at the bottom. This slowdown seems to occur even when there's virtually on oracle activity so I'm suspecting some other cause. Thanks, Jay Miller nycsun1 and njsun7 has 6 GB of memory and only 2 GB of share memory. This morning nycsun1 was very slow and I noticed that there was lots of swaping. see vmstst and iostat below in red: procs memorypagedisk faults cpu r b w swap free re mf pi po fr de sr s2 s4 s4 sd in sy cs us sy id 0 0 23 4366736 97528 1 2186 16 12 12 95520 0 0 0 0 0 1104 3330 974 11 8 81 0 0 23 4365992 96056 1 451 16 24 52 85968 3 0 0 0 0 935 847 416 3 1 96 0 0 23 4364712 95512 2 310 36 24 492 85968 68 0 0 0 0 1036 2183 670 13 4 84 0 0 23 4361568 95488 9 2264 0 76 964 95520 136 0 0 0 0 979 4065 607 12 6 82 0 0 23 4362384 96080 1 6 4 8 8 77376 0 0 0 0 0 975 465 457 2 1 97 0 0 23 4361944 95712 4 730 92 48 532 95520 64 0 0 0 0 1040 1859 734 8 3 89 0 0 23 4360424 95480 4 41 36 40 100 77376 7 0 0 0 0 986 1250 542 6 0 94 0 0 23 4361304 96096 3 264 76 36 88 88496 7 0 0 0 0 1037 942 665 5 3 92 0 0 23 4359680 95784 2 449 4 28 84 95520 8 0 0 0 0 922 1047 374 4 1 95 0 0 23 4359936 95464 2 544 4 20 332 95520 44 0 0 0 0 931 1095 384 2 2 96 /s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 0.00.00.0 0.0 0.00.00.0 0 0 c2t6d0 0.0 34.50.0 270.0 0.2 13.86.7 399.5 6 44 c5t12d0 -- swap disk 0.0 34.50.0 270.0 0.5 10.7 15.5 309.4 18 39 c5t13d0 -- swap disk This shows that the system is not effectively using memory.

RE: 1M STRIPE SIZE BEST?
Ethan, EMC is recommending a 2-cylinder stripe depth now (960KB) which is pretty close to the 1MB that Oracle's SAME (Stripe and Mirror Everything) configuration recommended in the Optimal Storage Configuration Made Easy paper. Other recommendations: - use at least 4-member or 8-member striped metavolumes to distribute load across multiple disk adapters on the back end; don't go above 8 though or you're likely to run into disk queue depth issues - use powerpath to do load balancing on the front end - put redo logs on the first hyper of the physical disk (outer hyper) Rich > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Post, Ethan > Sent: Wednesday, November 20, 2002 5:54 PM > To: Multiple recipients of list ORACLE-L > Subject: 1M STRIPE SIZE BEST? > > A number of papers recommend a stripe size of 1 M (even for EMC) for > volumes > containing data files.

The number is more than the numwidth specified. Try this
SQL> set numwidth 13
SQL> select trn_id from trnid;
Your numwidth is perhpas defined as 9; so anything of more precision is
displayed as exponetial notation; internally all numbers are stored the
same.
