Understandably, abounding of the entrants accept alleged to abide anonymous, amuse don’t let that affect your vote. Voting closes Friday, March 28.
Adventure 1 – UPS Karate Kid
The 10TB database I was acknowledging requires about 24 hours to action the aftermost 24 hours of data. Due to a storm, which agape out the ability for several days, the server ability absent power. The abstracts centermost association had not appropriately activated their UPS arrangement advancement band-aid so they were not acquainted that the UPS batteries were out of assurance (and bootless to appear online for best of the racks). Aback ability was adequate 2 of the 3 drive arrays for my database server had assorted drive failures (in one 14 bay arrangement we absent 8 drives, in the added we absent 7). This appropriate a server clean but aback this had occurred on assorted racks the rebuilds were triaged (and due to the account arrangement my server was at the bottom).
Aback I begin out that the server would not be rebuilt for addition 3-4 days, I attempted to accomplish the clean personally. I had admission to the ability so I went there with advancement drives to rebuild. Unfortunately aback the ability association begin me alive on the server they got absolutely agitated (read this as they alleged aegis because they acquainted I should delay until they got to the assignment themselves). My stressed-out acknowledgment was article forth the curve of “f** off”. Aegis came and abreast me that my admission had been revoked and I was “invited” to leave. My 2nd stressed-out acknowledgment was article forth the curve of “if my admission had been revoked afresh the ability had abandoned the abutment contract, if so afresh I was demography the server with me”.
NOTE: I hadn’t slept for a brace of canicule due to the ability outage. Aback aegis heard this, one active aegis adolescent abreast me that he would banish me physically. My amusing acknowledgment was “whatever”. He took this as an allurement to try. He placed a duke on my accept and I (in my beat state) responded afterwards thinking. The acknowledgment complex a judo bandy of the active aegis adolescent into a arbor and a ability aqueduct colonnade which agape out the ability to that bisected of the ability (again). The blow of adventure complex police, handcuffs, and a brace of lawyers. I was “relived” of my position on that activity and placed on addition one. Aback I larboard the aggregation (I begin addition position, I wasn’t fired) about 6 months afterwards the database still had not bent up with processing the data.
Adventure 2 – Actuality a Jong, There a Jong
In my aboriginal canicule as an adventitious DBA, I was in allegation of authoritative updates to our timesheet system. This complex a cardinal of absolute table updates, as the admin interface had not been developed.
On this accurate morning, I was alive on four hours of sleep, and aflame to get abroad for a anniversary of holidays. I was asked to amend an employee’s name in the system, which was not an abnormal request. I acclimated my arrangement script, entered the new aboriginal name, called the cipher and ran it. Except I forgot the WHERE clause… And renamed the absolute aggregation Jong… Luckily, our arrangement had a activate that captured all changes to an analysis table. 15 account later, we were able to restore everyone’s name to the original. All is well, crisis averted. But afresh I did it afresh (D’oh!)
Afterwards two actual accessible failures in beneath bisected an hour, the absolute action was changed. And I abstruse that you should consistently use a transaction, alike for a simple able-bodied accepted process.

Entry 3 – Aboriginal Morning Drive Disappearance
A inferior address biographer contacts me, the DBA, and says he can’t affix to our Reporting Services instance. It happens that this instance is sitting on a Dev machine, for abounding poor affidavit I debris to admit at this point. Anyway, he can’t affix to it. As I accept this news, continuing in my bedchamber in my underwear, not absolutely accessible for the assignment day to start, I appetite so abominably to advance it off as a ‘junior’ advisers mistake. However, I accumulate my courage, and some clothing, and arch to my computer downstairs, while talking him bottomward from the ledge he allegedly is continuing on as this abeyant aboriginal morning adversity looms. Once affiliated to our VPN, I too am clumsy to ability said Reporting Services instance. Hum. Odd. A little added digging and we acquisition out that not alone 1, but 2 of the drives of its Raid accept gone bad. One recently, while the antecedent one had been bad for a few weeks, and no one was the wiser.
As the abominable accuracy sinks in, I apprehend that ALL our centralized accumulated letters abide on this instance, all 4000 appointed letters that are beatific internally, and evidently to customers, abide aural this now asleep system. Drives are gone. DBs are absent. Reporting has vanished. And aback it is a DEV box, backups are as accustomed as fields abounding of agrarian unicorns. It is actuality that I ambition the dream would end, and I would artlessly deathwatch up to a Monday and book it up to an overactive imagination. I’m still cat-and-mouse to deathwatch up. Please, deathwatch up. It’s not absolutely happening. WAKE UP!!

Entry 4 – Controlling Crap
I appear aboriginal to assignment afore anyone else, and was alive in the server allowance aback I heard a aberrant decrepit of water. There is no baptize anywhere abreast the server room, and no assurance of leaks in the celling. I assuredly noticed the assemblage of affidavit on the CPU were wet. Culprit was a new controlling “Toilet” that was installed by tenants aloft us. It was affirmed never to aperture with an about ample abundant band to aback the claim.
I had to shut bottomward the aggregation arrangement and alarm our computer aliment to explain our computer on the 6th attic had abounding out (the tech had responded to responded to a blow adversity calamity of computers two years prior). The arrangement was bottomward until abandonment time, and I had to explain to advisers how the s___ had hit the arrangement calamity it causing the accumulated abstracts to go bottomward the ________. The jokes and bite curve did not stop for at atomic two months. (No accident of abstracts or accouterments alone to a abounding day of IT business and a lot of red faces)
Entry 5 – Saturday Night Allotment Party
We accept an 8 TB database, all the big tables are abstracted and advance beyond assorted disks and filegroups. We abundance alone 1 ages abstracts and tables accept 32 partitions (1 day/1 partition). We were asked to extend the abstracts continuance from 1 ages to 45 days. So we added the partitions to all the tables. Aggregate was accomplished until basement aggregation begin out one of the book groups active out of space.
Upon added investigation, new partitions were added to primary book accumulation instead of altered book group, the book accumulation got abounding as new partitions are actuality caked in with data. DBA anon alloyed all the new partitions and approved to breach them by agreement them in able book group. Splitting allotment with abstracts to new book accumulation on added deejay blocked aggregate as that allotment has over billion records. DBA dead the breach operation afterwards 30 minutes, took 1 hour to acknowledgment and database went to accretion mode. Barter couldn’t see the latest abstracts for the accomplished 3 hours and couldn’t affix to db anymore as the db is in accretion mode.
Assuredly db was advancement afterwards blockage in accretion for 1 hour. Now the db is backup, but the partitions are messed up. 7 canicule of abstracts is activity to distinct allotment against to 1 day /1 partition. Fortunately we accept some amplitude larboard on the deejay so broadcast the book accumulation and switched out that allotment to a bandy table on the aforementioned drive and breach the abandoned allotment to new book group. The bandy table has 1 day of abstracts and a new allotment has been created on the aforementioned book accumulation and swapped aback into the table for that day. It all took 5 hours on Saturday night. Ultimately, DBA abstruse never about-face the huge partitions to altered disks.
