Re: [OT] Oracle memory leak debugging
Well, we normally do this through an SR, as it generally requires the use of some internal technology which needs a support contract underpinning it. If you don't have a support contract/My Oracle Support account, contact me off list and I'll discuss what we can do. If you do, open an SR and let me know the SR number. The trace you have is a SQL*NET trace, which traces the interactions over the network. It's as much use as a chocolate teapot for what you're looking for :-) Cheers Damian -Original Message- From: Neale Ferguson [mailto:ne...@sinenomine.net] Sent: 29 May 2013 01:37 To: LINUX-390@vm.marist.edu Subject: [OT] Oracle memory leak debugging I am trying to determine why an Oracle app is using a lot of storage (and growing and growing). I am not sure if it¹s application related or not. Initially I saw lots of OCIParamGet() calls with no corresponding OCIDescriptorFree() calls. However, after correcting this there was no respite from memory consumption. Looking at the memory contents as the app runs to see what's in the new areas allocated I see lots of Alloc statemen eye-catchers. Statement handles are being created OCIHandleAlloc() and freed via OCIHandleFree() without error. This is Oracle 10g. Creating .sqlnet.ora with the following provides a lot of data but sheds no light: trace_level_client=16 trace_file_client=cli trace_directory_client=/tmp/oci trace_unique_client=true trace_timestamp_client=ON I'd really like to find out why Oracle believes the area cannot be freed. A similar app runs on Windows without a problem so I'd like some way of tracing all the OCI calls being made in both environments and compare them to see what magic incantation may be missing.

Only 3 (THREE) business days left to Register for the VM Workshop to get a polo shirt, dorm room, and parking pass.
Cross-posted to the IBMVM, Linux-390, and IBM-MAIN discussion lists. The registration deadline is set hard and fast as the end of day May 31, 2013 due to Indiana University - Purdue University Indianapolis (IUPUI) deadlines. For all registrations made before June 1: * dorm room reservation requests, and parking passes will be processed, * attendees will receive a 2013 VM Workshop polo shirt at the Registration table, * attendees will receive a $65 JagTag Debit Card for food purchases in the Campus Center food court at the Registration table. Online attendee registrations will be accepted after May 31, but not for dorm room reservations, parking passes, nor 2013 VM Workshop Polo shirts. Onsite attendee registrations will be accepted by credit card, check, and cash, but again not for dorm room reservations, parking passes, nor 2013 VM Workshop Polo shirts. Additionally, availability of $65 JagTag food court debit cards for onsite registrees will be delayed until those can be purchased and distributed manually. Don't delay! Besides, the two 2-part Hands-on Labs are expected to reach their maximum capacity of 30 each rather quickly. Why attend? Well... * the 2013 VM Workshop registration fee is still only $100, and * BRAND NEW double occupancy dorm rooms (pics at: http://www.vmworkshop.org/2013/housing) can be reserved before June 1 as a 3-night package for $150 (additional nights at $50 each), and * reduced rate Parking passes may be purchased for $20 before June 1, and * a 2013 VM Workshop polo shirt is included for registrations made before June 1, and * a lavish Thursday evening reception and dinner is included, and * a $65 IUPUI debit card for meals in the Campus Center is included, and * excellent technical sessions, and the same IBM-provided Hands-on Labs as presented at the 'bigger' conferences, and * the famous VM Workshop Ugly Hawaiian Shirt Contest is included (BYOUHS), and * famous and infamous speakers delivering up-to-date technical sessions on z/VM and Linux on System z topics all centrally located on the IUPUI campus in downtown Indianapolis, Indiana. All session slots are now 100% full. There have been rumors of a few late sessions, so some of those below might be replaced by newer sessions of more general appeal, and/or... session times adjusted. You may view each speaker's full session descriptions by visiting the current session agenda and schedule at: http://www.vmworkshop.org/2013/agenda To learn more about the 2013 VM Workshop, visit: http://www.vmworkshop.org/2013 You can review all public information at that URL, but to register you'll first need to request a VM Workshop ID (used only to minimize spambot attacks on the web site). Once you have been manually granted an ID by an admin, you may register for, and pay for (via Paypal) your purchases. Note: There are only 15 IBM-provided Hands-on lab laptops at each of the non-concurrent 'z/VM Install Config', and 'Linux on System z Install Config' labs. Once you have received a workshop ID, you may reserve a seat at one and/or the other labs (maximum attendee reservations for each lab = 30).

Re: Setting kernel parms for RHEL6
Hello, Bobby. kernel parameters can be specified on the parmeter= line in the /etc/zipl.conf file. Here's an example of an entry from my zipl.conf where I specify that a dcss should be loaded at boot time: [test] target = /boot image = /boot/vmlinuz ramdisk = /boot/initrd.img parameters = root=/dev/disk/by-path/ccw-0.0.0150-part2 dcssblk.segments=SWAPPING Note that the parameter line is just one long line and not split in two as shown here in this e-mail; there's a space between root= and dcssblk.segments= strings.

Re: Setting kernel parms for RHEL6
It's zipl.conf that you want. The 'zipl' command will read that config file, build a parm line and other static data, and stamp the IPL text onto the boot disk. Unlike some other bootstraps (eg: GRUB), here you need to re-stamp the IPL text when changing the parms. (That used to be the norm for all flavors of Linux.) About the terminal server (and this is new to me), you may need to add a second console= parameter so that the 3215/HMC driver continues to see traffic. Also, the console driver is just one of your options. There is an on-demand IUCV terminal service using the 'iucvtty' program. Might be helpful especially since it does not require a reboot. (You can test 'iucvconn' against it without having to do the ZIPL magic.) -- R; On Wed, May 29, 2013 at 2:51 PM, Bauer, Bobby (NIH/CIT) [E] baue...@mail.nih.gov wrote: Looked all through the Device Drivers.

Re: Setting kernel parms for RHEL6
You will need two pieces for using the hvc console... 1. The additional kernel parameters in zipl.conf. As Rick suggested, if you want to keep your 3270 console add another 'console=' statement. The 2nd console statement will be the primary console, fyi. In our case, we have the hvc console as primary, so our additions look like this on the parameters section of zipl: hvc_iucv=2 console=ttyS0 console=hvc0 2. An upstart job to maintain the tty's on those terminals. I choose to have an upstart for each hvc console. An example to maintain the tty on the first console: start on stopped rc RUNLEVEL=[2345] stop on runlevel [S016] respawn exec /sbin/agetty -L 9600 hvc0 xterm This is assuming you are wanting to use this console in case of a failed boot, etc. To then connect from another guest to the first hvc console you could issue: iucvconn guest lnxhvc0 I think that's about it.
