Splitter 1×4

[Yamila Comejo]

Iam trying to use the tag history splitter with two different databases, and a primary and standby gateway. Each gateway shares the same hardware as the DB. I am trying to achieve redundant history storage.

However, when I shut down the primary, and restart it, the history is not there for the duration the primary was down. My understanding from the manual is that the store and forward system should be storing the history for the DB that is down, and when it comes back up, the store and forward should be restored.

I killed the process for the gateway and the database to simulate a machine shutdown, but I needed the computer still up so I could VNC into it, otherwise I have no connection after it goes down as I am working remote. (This machine has two NICs, so its the only PC I can access on the network. I can't access the secondary without this connection. During the time the processes were down (half an hour) no data was able to be retrieved when it came back up.

Yes, I agree, I thought this might be the case, but I didn't understand why it is listed there at all then under store and forward status if it is not relavent, so I had my doubts about my understanding.

I wish I could do this, but I am using postgres on windows 10 and there are no reasonable solutions which will manage failover, despite it being able to support replication. I could attempt to roll my own, but it would be highly risky.

So I was hoping to rely on store and forward. The requirements aren't super strict, I can handle a little data loss, but it just doesn't seem to capture anything at all when the primary machine goes down. Well it probably does on the backup server, but when my primary server is up, I can't see this data.

I'm not familiar with postgres replication, but if it can do master-master replication then just set a single database connection to localhost as the IP address and postgres should do the rest of the work to ensure the databases stay in sync.

Also, is your backup running in the cold mode or warm mode? If it is running in the warm mode, that would mean that Ignition would be writing tag values to both databases at the same time which would cause double the amount of values to be written in the master-master replication.

EnterpriseDB, the commercial sponsor of PostgreSQL, has extended the base to provide multi-master replication, with some support for non-PostgreSQL participants. The EnterpriseDB solution appears to be the path most users choose.

Wow, looks good, I had no idea this was out there. My only concern is around licensing, is this free to use in a scada application? I can't see where it says anything about it, unless you are using their cloud services.

Splitters are often referred to as "split-finger fastballs," but because of their break and lower velocity, they don't hold much in common with a typical fastball. As such, Statcast classifies splitters as an offspeed pitch.

A splitter is thrown with the effort of a fastball, but it will drop sharply as it nears home plate. Splitters are generally thrown in the same situations that would see a pitcher throw his breaking and off-speed pitches. They're generally only slightly faster than a changeup, and sometimes a pitcher's offspeed pitch will be a combination between the two, called a "split-change."

Splitters are a relatively uncommon offspeed pitch, but they are still used with some prevalence. The splitter is a much more common pitch in Japan's Nippon Professional Baseball, and Japanese pitchers who come to the Major Leagues often bring a splitter with them.

A pitcher throws a splitter by gripping the ball with his two fingers split in a "V" shape on opposite sides of the ball -- often even on the outside of the seams. With its deceptively slower velocity and sharp drop, a splitter is designed to get the hitter's bat ahead of the pitch and induce weak contact.

The splitter evolved from the forkball. The two pitches are gripped in almost the same way, except a splitter is generally held with more ease and placed toward the top of the fingers. Splitters are also thrown with the same minimal wrist action as a fastball, unlike the wrist-snap used for a forkball. The splitter received a great deal of recognition thanks to Hall of Fame reliever Bruce Sutter, who threw the pitch with regularity, and the pitch is now popular thanks to stars like Shohei Ohtani.

I'm working on a roundabout design in Civil3D 2018 and I'm having trouble with the outer offsets for the splitter islands. Whenever I try to set them to 3 and 1, they reset back to zero. Does anyone know how I can get these offsets to stick?

A split-finger fastball or splitter is an off-speed pitch in baseball that initially looks to the batter like a fastball but then seems to drop suddenly. Derived from the forkball, it is so named because the pitcher puts the index and middle finger on different sides of the ball.[1]

The splitter grew out of a much older pitch, the forkball, which was first used in the major leagues in the 1920s.[2] The modern splitter is often credited to baseball coach Fred Martin, who threw the pitch in the minor leagues as a changeup of sorts. When a young Bruce Sutter returned from surgery to find his fastball had lost velocity, Martin taught Sutter the pitch.[3] Sutter's success as a closer helped popularize the pitch.

Another early proponent of the splitter was Roger Craig, a pitcher-turned-manager, in the 1980s. He taught it to a number of pitchers on the teams he coached, the Detroit Tigers and San Francisco Giants.[2] Longtime player and manager Mike Scioscia called the splitter "the pitch of the '80s."[1]

The splitter eventually lost popularity in MLB after concerns arose that extensive use of the pitch could rob pitchers of fastball speed[4] and increase injury risk[5] Several major league teams discourage pitching prospects from throwing or learning the pitch.[1] In 2011, only 15 starting pitchers used it as part of their regular repertoire.[6] Splitter usage has begun to see a resurgence in the 2020s, with little research indicating support for the increased injury risk, and the MLB success of Japanese splitter-throwers from NPB, where the splitter has long been a primary pitch, as key factors.[5]

The split-finger grip is similar to the forkball grip; however, the forkball is held farther back and wider between the fingers and is usually thrown with a wrist flip that makes it slower than the splitter.[7] The split-finger is often recommended as an alternative to breaking pitches to young players because of its simplicity and the significantly reduced risk of injury.

An off-speed pitch, the splitter is generally thrown slower than that pitcher's fastball. According to PITCHf/x, the average four-seam fastball from a right-handed pitcher in 2010 was 92 mph, whereas the average splitter was 85 mph and the average changeup 83 mph.[8]

The motion of a split-finger pitch is similar to the outlawed spitball and at one time the pitch was known as the "dry spitter". When thrown, the pitcher must emphasize the downward pull of the pitch at the end of his motion. Thrusting the hand and forearm downward causes reduced backspin relative to a fastball, thus giving the appearance of "drop off the table" movement from the pitch. When thrown correctly, the split-finger's apparent last-second drop causes many batters to hit the top half of the baseball, thereby inducing a ground ball. The split-finger fastball is a very effective pitch with runners on base; a common tactic is using the split-finger to cause the batter to hit into a double play.

Bruce Sutter, a Hall of Fame inductee, was a dominant closer in the 1970s and '80s and made heavy use of the split-finger pitch. He won the 1979 Cy Young and became the only National League pitcher to lead the league in saves 5 times.

David Cone was famous for his splitter, used most often in the middle and later part of his career. A major strikeout pitch for him, Cone would throw it harder like a fastball to get swinging strikes. He also was very effective in throwing it slower, using it as a changeup to throw off hitters' timing. Jack Morris learned the pitch from Roger Craig in 1980, and it became an effective "out" pitch for the Tigers' hurler. Mike Scott also learned the pitch from Craig after the 1984 season, and it turned his career around. He won the 1986 NL Cy Young award and posted a league-leading 306 strikeouts.

The Clearfield WaveSmart Ruggedized Splitter is the standard splitter component in its line of FieldSmart FSC OSP Cabinets. The splitter addresses environmental and human handling issues that other standard splitters in the industry cannot combat. It provides improved fiber protection, management and maintenance in OSP FTTx deployments.

I am trying to import oracle table to HDFS directory, but getting the error "Generating splits for a textual index column allowed only in case of "-Dorg.apache.sqoop.splitter.allow_text_splitter=true" property passed as a parameter"

I fixed the import issue by giving "-Dorg.apache.sqoop.splitter.allow_text_splitter=true" in sqoop import. But why do we need to set this property? I imported other tables without setting this property. When should we set this property?
