Remote Debugging Attachment to a WebLogic Server

Don’t believe everything you’ll find online. If you work in a moderately complex environment (meaning, you’re running a managed server instance via an admin server instance on WebLogic), you’re sure to be led astray by the dozens of articles offering guidance into this elusive technique. You don’t have to emulate Ray Milland, if you follow this advice:

If you Google “Remote debugging WebLogic” you’ll find a host of discussions about modifying the startWebLogic.cmd or startWLS.cmd files. Ignore them all (assuming you’re using WebLogic 8.1 or later)! (Also remember, never verb a noun.)

Let me review the scenario that I am actually addressing here:

  • You will be remote-attaching to a running WebLogic instance, rather than launching the instance from within your IDE. (I use Eclipse, because I’m cheap—and because version 3.1.1 really works great, unlike its predecessors—but these instructions apply to just about anything.)
  • You run your WebLogic application as an instance under a WebLogic managed server, and start/stop it using the Remote Start options in the WebLogic console.
  • You’ve tried desperately to get your debugger to attach, or your breakpoints to be hit, to no avail.
  • You have deadlines looming, and if you don’t get this one problem solved, you can never see your family again.

Okay, perhaps I went a bit overboard on the scenario, but if you’re reading this, I expect, like me, BEA’s WebLogic isn’t a platform you use every day, but one that you need to work on occasionally.

The key is that most of the documentation presumes you won’t be running your application from the WebLogic Server Console, and gives no indication that the JVM arguments, in such a case, go in a completely different place. Here’s how to prove to the world that you weren’t going insane:

  1. Log on to the WebLogic console, via http://{servername}:9999/console. YMMV as far as the port number (after {servername}) is concerned.
  2. Using the navigation tree, click on the domain on which your application resides, open the Servers branch beneath it, and click on your application’s name.
  3. With the Configuration tab in the top row selected, click on the Remote Start tab in the second row. (Be sure you don’t have Control selected in the top row, otherwise you’ll think I am just as batty as the authors of the previous 743 help documents you’ve read.)
  4. Scroll down to the Arguments: field, and add your debug settings to the JVM arguments in that field. In my case, I added -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n, which (among other things that are too cool for me to share) allows the debugger to attach to port 8787 (address=8787), and the server to start without waiting for a debugger to attach (suspend=n).

  5. Click on Apply.
  6. Then click on Control in the first row of tabs, and be sure Start/Stop is selected in the second row of tabs.
  7. Finally, you’ll need to either gracefully or forcefully shut down the server by using the links provided, and then restart the server. (You’re actually only restarting your application; the ambiguous language surrounding server is another problem.)
  8. Attach Eclipse to the server by Configuring a new Remote Java Application under Debug … Feed it parameters of the server name and 8787 (or whatever port you provided in the JVM arguments).

  9. Debug your problem.
  10. For goodness’ sake, go home and see your family!

Drop me an e-mail using the link in the sidebar, or leave a comment, if I’ve goofed anywhere. I never claimed to be perfect. Sheesh.

Mostly Mummies: Our MFA Trip

Never visit the Museum of Fine Arts in Boston without being accompanied by Debi Costine. Back on February 27, we got to do just that.

Nichelle spent the three days before the trip in “intense rest,” hoping to be well enough to go with us. (I hadn’t seen her so determined to do anything major since singing in the Christmas program in mid-December.) Thankfully, she was able to go, although by the end I wished I insisted she use a wheelchair for at least part of it. (In the weeks since, her condition has gotten worse, and I don’t think we’d even try such a trip now.)

We also weren’t sure we could convince David to come. He seemed fascinated, several years earlier, by the mummy at the Museum of Science in Boston, but in the interim years, that fascinating had turned to fear. I spent three weeks trying to psych him up, but it was Debi who spoke to David the night before and convinced him that he would be fine. By the end of her call he was eagerly anticipating the trip.

Above: Debi Costine provides an introduction to ancient Egypt.

What a wonderful trip! The kids loved it, John especially favored this museum over the science-centered ones that I typically drag him to.

Outside the Egyptian wing, Debi sat us down, gave us handouts, and introduced us to things to look for in the Egyptian artifacts. Among them was a cartouche—generally an ellipse with a line on one side, that would be marked with one or two sets of hieroglyphs. This would indicate the name of a god or a king. We also learned about the burial and afterlife beliefs of the ancient Egyptians, including the false door that the spirits would use to retrieve food offered to them.

One of the things Debi stressed was the grain of truth that many cultures preserved after the Flood in their understanding of spiritual things. It was very interesting to see how a proper understanding of death and eternity became corrupted over the years.

Above: Pointing out the hieroglyphs adjacent to a cartouche, indicating the name of a god. (Note Debi’s red hair.)

One of the ideas I found fascinating was that the existence of one’s name carved in stone allowed the existence in the afterlife to be perpetuated. In some cases, pharaohs or other leaders who fell out of favor were “eliminated” after death by having the names chiseled out of their places, as well as statues destroyed. One pharaoh ordered his name hieroglyphs to be carved especially deep. I wonder if it occurred to them to carve it someplace and then hide it.

Above: Barley (along with a crude mortar and pestal) dating from up to 6,000 years ago.

When Nichelle and I attended the MFA last year, we were awestruck by the Egyptian artifacts. They project such a feeling of age. It is truly amazing to walk among them. The barley shown above is a small thing, but it’s astounding to find it preserved for five or six millenia.

Above: King Menkaure (Mycerinus) and queen (possibly Khamerernebty II).

I absolutely love this statue of King Menkaure and his queen. This couple is elegantly and lovingly rendered, and it impresses me that the artists were able to perfectly recreate the effects of sheer cloth in a stone statue. Note that they are actually clothed, at least in the custom of the time. The statue is unfinished. (There is no name on it; the king’s kilt pleats are not carved, and the base is unfinished.) There are more photos, a write-up, and an audio piece here at the MFA site. Note the folded napkins in Menkaure’s hands. These were authority symbols. Some later statues had rectangular napkins that look more like blocks of wood.

Above: The Egyptian kings would place these stories about their conquests on the borders of their lands. Debi was able to explain the story carved here in much more detail than the museum plaque next to it.

Above: Check out the cartouches on the base of this statue. These have the hieroglyph pairs we were hunting: a sun with a bird, and a bee with a sedge plant. David just told me, “I was the first one who found that one!”

Above: All the geeks in ancient Egypt used these these snazzy pocket protectors. Seriously, it’s a scribal palette, belonging to “The royal draftsmen of the Lord of the Two Lands, Amenemwia.”

Above: The center of the Egyptian funerary room. That’s a bolt of linen in the left foreground that is over 4,000 years old. Amazing!

The funerary room was astounding. It offered much more than the few things we think of as stereotypical Egyptian art surrounding the funeral rituals. Interestingly, the Egyptians were quite reluctant to change the formulae of their rituals, even over the centurals. So, even when the custom of removing the organs and storing them in jars had changed, faux jars were still placed in the burial chamber.

Above: These ceremonial eyes were painted on the sides of coffins to allow the body entombed within to see out.

Above: Debi noticed something about this mummy mask that she had never seen before: It has a beard. This mask (dating from the time around Joseph’s life) may show the result of a Hebrew influence, as the Egyptians didn’t wear real beards, perhaps as a result of Joseph’s revelation of his origin and rise to power.

Above: You’ve read the Old Testament many times, but always wondered what Baal looked like. Now you know! (This one is missing his weapon or thunderbolt. Maybe it was a child’s action figure. It’s about the same size. “Hey, kids! Collect all the Canaanite deities!”)

Above: This Hittite stamp-cylinder seal was impressive, as were the other seals and commercial artifacts, including a set of balance weights and numerous cuneform tablets.

Outside of the Egyptian area, was one of the things we were all really looking forward to seeing: A fragment of a plate (probably smashed by the forces of Alexander the Great) from one of Xerxes four palaces. Debi likes to encourage her students to imagine that Queen Esther herself may have touched it.

Above: Fragment of a Royal Plate
Southwest Iran (probably from Perseopolis, Palace of Xerxes), 485–464 B.C. Diorite. Queen Esther just might have used it. (My photo is blurry, so I’ve linked the image to a better one at the MFA.)

By the time we got to the few more modern things we looked at (much of the 1st century A.D. art, especially from Corinth, is, shall we say, inappropriate for children), they just couldn’t compare to the marvel of the ancient Eyptyian work. They all seemed so … recent.

Above: This painting contains owls hidden within it. I was terrible at finding them, but the kids did well, and really enjoyed the task. This photo isn’t perfect, but I couldn’t find the painting this evening when I searched the online MFA database—even though I found it a few weeks ago.

I’ll also include what is one of my absolute favorite paintings in the MFA. When I first saw it, during my company’s “Winter Thaw” event, I was struck by how beautiful it was. The color is amazing, and it seems photographic in its realism. It really stands out.

Above: Portrait of a Young Woman, possibly Countess Worontzoff, by Marie Louise Elisabeth Vigée‑Le Brun. French, 1755–1842.

And David, the little weasel, announced that his favorite part had been the mummies.

Another Dead End: Endocrinologist II

Nichelle heard back from the most recent endocrinologist’s office. Here are his notes:

  • No further assessment
  • Fasting plasma glucose at some point in the future, not running any more tests.
  • Maybe another fasting glucose—talk to the PCP about that
  • Can find nothing from an endocrine standpoint

However, the office is checking on a referral to an endocrinologist in Boston.

This is really, really frustrating. Hypothyroidism on top of fibromyalgia explains nearly all of Nichelle’s symptoms. Every doctor except the endocrinologists Nichelle has seen seems to think this exhibits as a clearly endocrinological problem.

I’m going for a walk.

Later news:

Nichelle has been referred to a specialist in Boston. The endocrinologist did agree to the referral, and will be following up on the results. This is some progress.

Another Appointment … Rheumatologist II

Today I had my appointment with the new rheumatologist. He’s requesting all records from three different doctors. I was given a new pain med and taken off one that I was recently given by the ER doctor (although I’ve only taken it once). I will have a follow-up appointment in four weeks.

He has no explanation for several of my symptoms, but states the other problems that I’m having is fibromyalgia. Here’s a great site to find out more about fibromyalgia: http://www.fibromyalgia-symptoms.org.

The doctor today, too, agrees that the other problems that I’m having are endocrine. I am also waiting to hear back from the new endocrinologist. He wanted to go over my tests results from the first endocrinologist, who claimed that I didn’t have an endocrine problem!

I have been checking my temperature for several days now and the highest it’s been is 98.0 and the lowest was 96.3. The typical range in 97.2 to 97.7.

Next week I have an appointment at the pain management clinic.

Waiting, praying, hurting, and crying, but through it all we know God is ultimately in control and already knows the outcome. Thank you for your continued encouragement and prayers.

Endocrinologist II: Not Much to Tell (Yet)

Nichelle was very impressed with the endocrinologist she visited today. She described him “as thorough as Dr. Rescigno,” which is a huge compliment.

Dr. Bhaghayath took an interest in everything Nichelle brought in (unlike the last two doctors she has seen), including things that seemed “off-topic,” such as the bone scan results. He was amazed by the photos showing the water retention. He reviewed our symptom list, and commented that Nichelle had “a lot of things going on.” He wanted to know if Nichelle had a family history of thyroid problems. (Getting a family medical history for either one of us is a rather amusing undertaking.)

Nichelle did ask him to confirm any connection between the vitamin D deficiency and the serious symptoms she is now experiencing. As we expected, he said they were “totally separate,” but Nichelle wanted a second opinion.

Unfortunately, some critical records were not sent over, despite the fact that Nichelle checked on them this morning. His concern is that (just as Beth has suggested), critical endocrinology tests were missed, and only the cursory levels were measured, especially for thyroid function.

He’s going to examine the records, after Nichelle kicks some butt to get them sent over, and call Nichelle back. (This appears to be a failure in the medical records department, rather than the doctor’s office, for a change.)

Millions and Millions? (Answers in Genesis – MVBC Conference)

Note: Ken Ham, and indeed all of Answers in Genesis and similar organizations, is, I can no longer conclude otherwise, simply a liar. I’ve experienced it in person. Anyone who suggests that young earth creationism can be supported scientifically is

I’m going to leave this link from the excellent BioLogos organization to illustrate a common problem: AiG consistently and constantly misrepresents reality. https://biologos.org/articles/soft-tissue-in-dinosaur-bones-what-does-the-evidence-really-say . I choose this because I’ve heard Ken Ham, in person, completely misrepresent the work of paleontologist Mary Schweitzer. Enough!

The previous parts of this post were were written when I was ignorant.

—–

Yesterday evening the boys and I attended the Answers in Genesis conference hosted by Merrimack Valley Baptist Church, featuring Dr. Ken Ham. (See event details, including driving directions here.)

There are two more sessions this evening. I highly recommend attending. Dr. Ham is an excellent presenter, and teaches in ways that are both fascinating and amusing.

I’ve now attended three different Creation Science conferences: Dr. Ham’s presentations are on par with the excellent work of the Institute for Creation Research. (There is a third, very well-known Creation Science presenter I’ve seen whose seemed to go off-topic at times, and who left me feeling he was a bit loopy when he did so.) [No, ICR and AiG are not excellent. The other guy mentioned was and is racist and vile. I was very, very ignorant.]

There were a few things which were of particular interest to me, although everything was interesting:

  • Not a single point mutation ever studied has resulted in an increase of genetic information: They have all (all that we have studied so far, at least) removed information. It turns out that the things we dread, like bacterial resistance to antibiotics, are due to genetic information being lost from the strains. (In one specific example, mutation removed the ability to produce an enzyme that converted the antibiotic to poison within the bacterium, making a particular antibiotic ineffective.) [No, this is not remotely true.]
  • The explanations of how specific breeds of dogs show subsamples of a more genetically diverse gene pool were excellent. He referred to his wife’s expensive-to-care-for hypoallergenic poodle-type dog as, “my wife’s degenerate, mutant dog.” I have always been fascinated by genetics, and enjoyed this part of the presentations immensely. [No, this is not remotely true, and is an entirely nonparallel comparison.]
  • During an explanation of 14C (Carbon 14) dating versus K-AR (Potassium-Argon) dating, Dr. Ham presented a find from a mine in Australia, where samples of fossil trees (not petrified) were found embedded in the bottom of a basalt layer. The layer was K-AR dated at 36 to 45 million years old, while the wood was radiocarbon dated to about 45,000 years old. They can’t both be correct, especially as 14C isn’t supposed to persist in measurable quantities for more then 100,000 years. [No, this is not remotely true; the single sample so found was mishandled and contaminated.]

Dr. Ham has blogged about this conference himself here.

Enjoy.

Big News: Doug Bakes … from Scratch

Last night, Doug mentioned that he wanted to make banana bread. Now this is major.

So, after dinner, he and Naomi headed out to the neighbors to get 1/2 cup of shortening. He tried a few homes before getting some. The only thing I had to do was put out the ingredients, and he and Naomi did the rest.

The finished product looked great and tasted great. I was very impressed. I told him, “This is just the beginning, just think of all of the things you can start making.” He wasn’t all that keen on that idea, but this morning he mentioned to Naomi that they can make more this weekend.

Doug’s teaching techniques are quite unique, too. I found him telling Naomi, “You have to let go your aggression on the bananas … feel the hate,” when they needed to be mashed. Waaaaay too much Star Wars influence here. She had a lot of fun, and Doug commented that it was fun working with her, too. Naomi also likes to help me cook, so she now gets the teaching from both of us. Which is of course helpful for her to be well rounded.

Paging Dr. House …

This is the kind of doctor we need.

Nichelle asked me to post some notes from today’s somewhat discouraging doctor’s visit. This was an apointment with a new doctor, who, we hoped, based on recommendations and screening, would listen carefully to the symptoms and be determined to find a solution. Instead, we are being asked to visit specialists in fields we have already visited, and have little to be encouraged about.

Here’s what was observed at the appointment:

  • Nichelle is now 5′ 6″ tall—two inches taller than the last time she was measured (some years ago; one doesn’t expect to get taller after the age of 25 or so). (Note: We don’t have a good benchmark for when this growth occurred; we’re trying to find out.)
  • Today she had a 101.2° fever, and was unaware of it. (When’s the last time you ran a slight fever and felt no different than any other time?)
  • Her blood pressure was slightly elevated.
  • Her weight has reached a new high.

Her new doctor wants her to see another rheumatologist, and another endocrinologist, and work with a pain management center (Southern New Hampshire Medical Center has one).

He believes the hair loss is an endocrinological problem. (Our endocrinologist who is treating Nichelle for vitamin D deficiency had no explanation for this particular symptom.)

The new doctor concluded that successful pain management would allow exercise, and that would lead to weight loss, despite the fact that the onset of these latest, ever-worsening symptoms that struck last fall occurred—contrary to typical fibromyalgia—during a long period of significant daily exercise combined with careful diet, which, incidentally, did not produce any weight loss.

Nichelle really feels like yet another doctor is not truly listening to her. I’m not completely convinced that’s the case, because he did immediately recommend two specialists and the pain clinic, so it’s not like he’s saying nothing’s wrong—it’s just that we can already discount one of his conclusions and he’s not really willing to listen to that (yet). The biggest problem is we have a neurologist who has a marvelous doctor-patient manner, and just projects a vast amount of caring, even when he is hearing about symptoms he can’t correct in his speciality. Nichelle called him yesterday, because he wanted to be kept informed of her overall medical issues—that’s not very common in a specialist. So, just about every doctor we’ve ever had seems inadequate in comparison.

I wanted to quote Job 10:2–3, 8 for this post, but Nichelle wouldn’t let me, so I’ll go with some verses from Psalm 30 instead, although when I heard these this morning (especially verse 2) they made me cry:

1I will extol Thee, O LORD; for Thou hast lifted me up, and hast not made my foes to rejoice over me. 2O LORD my God, I cried unto Thee, and Thou hast healed me.

10Hear, O LORD, and have mercy upon me: LORD, be Thou my helper. 11Thou hast turned for me my mourning into dancing: Thou hast put off my sackcloth, and girded me with gladness; 12To the end that my glory may sing praise to Thee, and not be silent. O LORD my God, I will give thanks unto Thee for ever.

Psalm 30:1–2, 10–12

A Friday Night Date with My Wife: E.R. Live!

Friday night Nichelle and I determined we hadn’t been out together in a while, so when I got back from the Museum of Science with the Quinlans, we decided to go someplace somewhat exclusive and very fancy, that we’d never tried before.

We were impressed with the curbside service—a staff member actually came out to the door and showed us in, which is a level of service far above that to which we are accustomed.

Once inside, we disocovered there would be quite a wait—this place is popular—so we settled down to wait a bit in the lounge. We were impressed by the obvious expense that had gone into the venue. Millions of dollars had been spent on making this place stand out from its competition, and everything looked beautiful, even though some parts were still being renovated.

We were at the renovated (but still expanding) Southern New Hampshire Medical Center‘s emergency department.

Nichelle had been in severe pain from Thursday afternoon on, and by Friday evening it had gotten unmanageable.

After a brief wait (only about 4 hours)—next time Nichelle will need to be either bleeding profusely or pregnant to ensure rapid attention—they got Nichelle checked in, and administered a couple of different drugs by IV, the second of which actually helped. She was still having severe, stabbing pain in her ribs every 5 to 10 minutes, but most of the other pain was significantly reduced.

At 5:00 a.m., she’d been released, and we took a trip through our favorite drive-through: Brook’s Pharmacy, and watched the sky brighten with dawn. How romantic!

This morning Nichelle is feeling much better. The grip of the pain seems to have lessened, and she’s able to move around again without difficulty. She even made me a breakfast sandwich (when I finally got out of bed around 11:30), and played a few rounds of Burnout 3: Takedown with Isaac, David, and I, which she hasn’t done in months!

This brings me to an interesting, if merely anecdotal, observation about the pain she constantly suffers, which varies in severity. It would seem, based on how much better she was this morning, that the medication delivered by IV interfered with a feedback loop that was keeping the pain severe and inceasing it in severity. In short, stopping the pain temporarily led to stopping the pain for a much longer period. Fascinating.
