The mission of the District is to provide safe and reliable operation, maintenance and enhancement of the Golden Gate Bridge and to provide transportation services, as resources allow, for customers within the U.

Highway Golden Gate Corridor. Skip to Main Content. In coordinated mode, Replicat is threaded. One coordinator thread spawns and coordinates one or more threads that execute replicated SQL operations in parallel.

A coordinated Replicat uses one parameter file and is monitored and managed as one unit. See Section Integrated mode is supported for Oracle versions In integrated mode, Replicat leverages the apply processing functionality that is available within the Oracle database.

Within a single Replicat configuration, multiple inbound server child processes known as apply servers apply transactions in parallel while preserving the original transaction atomicity.

You can delay Replicat so that it waits a specific amount of time before applying the replicated operations to the target database.

A delay may be desirable, for example, to prevent the propagation of errant SQL, to control data arrival across different time zones, or to allow time for other planned events to occur.

Various parameters control the way that Replicat converts source transactions to target transactions. To support the continuous extraction and replication of database changes, Oracle GoldenGate stores records of the captured changes temporarily on disk in a series of files called a trail.

A trail can exist on the source system, an intermediary system, the target system, or any combination of those systems, depending on how you configure Oracle GoldenGate.

On the local system it is known as an extract trail or local trail. On a remote system it is known as a remote trail. By using a trail for storage, Oracle GoldenGate supports data accuracy and fault tolerance see Section 1.

The use of a trail also allows extraction and replication activities to occur independently of each other. With these processes separated, you have more choices for how data is processed and delivered.

For example, instead of extracting and replicating changes continuously, you could extract changes continuously but store them in the trail for replication to the target later, whenever the target application needs them.

The primary Extract and the data-pump Extract write to a trail. Every online Extract process must be linked to a trail.

Only one primary Extract process can write to a given local trail. All local trails must have different names. Multiple data pump Extract processes can each write to a trail of the same name, but the physical trails themselves must reside on different remote systems, such as in a data-distribution topology.

For example, a data pump named 1pump and a data pump named 2pump can both reside on sys01 and write to a remote trail named aa.

Data pump 1pump can write to trail aa on sys02 , while data pump 2pump can write to trail aa on sys Data-pump Extract: Extracts DML and DDL operations from a local trail that is linked to a previous Extract typically the primary Extract , performs further processing if needed, and transfers the data to a trail that is read by the next Oracle GoldenGate process downstream typically Replicat, but could be another data pump if required.

By default, trails are stored in the dirdat sub-directory of the Oracle GoldenGate directory. Trail files are aged automatically to allow processing to continue without interruption for file maintenance.

When the sequence number reaches , the numbering starts over at , and previous trail files are overwritten. You can create more than one trail to separate the data from different objects or applications.

Transactional order is preserved. In some configurations, Oracle GoldenGate stores extracted data in an extract file instead of a trail.

The extract file can be a single file, or it can be configured to roll over into multiple files in anticipation of limitations on file size that are imposed by the operating system.

In this sense, it is similar to a trail, except that checkpoints are not recorded. The file or files are created automatically during the run.

The same versioning features that apply to trails also apply to extract files. Checkpoints store the current read and write positions of a process to disk for recovery purposes.

Checkpoints ensure that data changes that are marked for synchronization actually are captured by Extract and applied to the target by Replicat, and they prevent redundant processing.

They provide fault tolerance by preventing the loss of data should the system, the network, or an Oracle GoldenGate process need to be restarted.

For complex synchronization configurations, checkpoints enable multiple Extract or Replicat processes to read from the same set of trails.

Checkpoints work with inter-process acknowledgments to prevent messages from being lost in the network. Oracle GoldenGate has a proprietary guaranteed-message delivery technology.

Extract creates checkpoints for its positions in the data source and in the trail. Because Extract only captures committed transactions, it keeps track of the operations in all open transactions, in the event that any of them are committed.

This requires Extract to record a checkpoint where it is currently reading in a transaction log, plus the position of the start of the oldest open transaction, which can be in the current or any preceding log.

To control the amount of transaction log that must be re-processed after an outage in an Oracle database, Extract also persists the current state and data of processing to disk at specific intervals, including the state and data if any of long-running transactions.

If Extract stops after one of these intervals, it can recover from a position within the previous interval or at the last checkpoint, instead of having to return to the log position where the oldest open long-running transaction first appeared.

Replicat creates checkpoints for its position in the trail. Replicat stores these checkpoints in a table, known as the checkpoint table , in the target database and also in a checkpoint file on disk.

The checkpoint table is stored with a user-specified name and location. The checkpoint file is stored in the dirchk sub-directory of the Oracle GoldenGate directory.

At the completion of each transaction, Replicat writes information about that transaction to a row in the checkpoint table, linking the transaction with a unique position in a specific trail file.

Replicat also writes a checkpoint to the checkpoint file when it completes a transaction. At regular intervals, Replicat also writes its current read position to the checkpoint file.

These positions are typically not at a transaction boundary, but at some point within a transaction. Because the checkpoint table is part of the database, and benefits from the database recovery system, it provides a more efficient recovery point for Replicat.

O'Shaughnessy , city engineer of San Francisco, and Strauss. The name became official with the passage of the Golden Gate Bridge and Highway District Act by the state legislature in , creating a special district to design, build and finance the bridge.

Strauss was chief engineer in charge of overall design and construction of the bridge project. Strauss's initial design proposal two double cantilever spans linked by a central suspension segment was unacceptable from a visual standpoint.

The final graceful suspension design was conceived and championed by Leon Moisseiff , the engineer of the Manhattan Bridge in New York City. Irving Morrow , a relatively unknown residential architect, designed the overall shape of the bridge towers, the lighting scheme, and Art Deco elements, such as the tower decorations, streetlights, railing, and walkways.

The famous International Orange color was Morrow's personal selection, winning out over other possibilities, including the US Navy's suggestion that it be painted with black and yellow stripes to ensure visibility by passing ships.

Senior engineer Charles Alton Ellis , collaborating remotely with Moisseiff, was the principal engineer of the project.

He penned a graceful steel arch spanning the fort and carrying the roadway to the bridge's southern anchorage.

Ellis was a Greek scholar and mathematician who at one time was a University of Illinois professor of engineering despite having no engineering degree.

He eventually earned a degree in civil engineering from the University of Illinois prior to designing the Golden Gate Bridge and spent the last twelve years of his career as a professor at Purdue University.

He became an expert in structural design, writing the standard textbook of the time. In November , Strauss fired Ellis and replaced him with a former subordinate, Clifford Paine, ostensibly for wasting too much money sending telegrams back and forth to Moisseiff.

With an eye toward self-promotion and posterity, Strauss downplayed the contributions of his collaborators who, despite receiving little recognition or compensation, [23] are largely responsible for the final form of the bridge.

He succeeded in having himself credited as the person most responsible for the design and vision of the bridge. The Golden Gate Bridge and Highway District, authorized by an act of the California Legislature , was incorporated in as the official entity to design, construct, and finance the Golden Gate Bridge.

The bonds were approved in November , [18] by votes in the counties affected by the bridge. However, the District was unable to sell the bonds until , when Amadeo Giannini , the founder of San Francisco—based Bank of America , agreed on behalf of his bank to buy the entire issue in order to help the local economy.

Construction began on January 5, McClintic and Charles D. Marshall, both of Lehigh University. Strauss remained head of the project, overseeing day-to-day construction and making some groundbreaking contributions.

A graduate of the University of Cincinnati , he placed a brick from his alma mater's demolished McMicken Hall in the south anchorage before the concrete was poured.

He innovated the use of movable safety netting beneath the construction site, which saved the lives of many otherwise-unprotected ironworkers.

Of eleven men killed from falls during construction, ten were killed on February 17, , when the bridge was near completion and the net failed under the stress of a scaffold that had fallen.

The platform fell into the safety net, but was too heavy and the net gave way. Nineteen others who were saved by the net over the course of construction became members of the Half Way to Hell Club.

The project was finished and opened May 27, The Bridge Round House diner was then included in the southeastern end of the Golden Gate Bridge, adjacent to the tourist plaza which was renovated in During the bridge work, the Assistant Civil Engineer of California Alfred Finnila had overseen the entire iron work of the bridge as well as half of the bridge's road work.

In and , the bridge was retrofitted with lateral and diagonal bracing that connected the lower chords of the two side trusses.

This bracing stiffened the bridge deck in torsion so that it would better resist the types of twisting that had destroyed the Tacoma Narrows Bridge in The bridge-opening celebration began on May 27, , and lasted for one week.

The day before vehicle traffic was allowed, , people crossed either on foot or on roller skates. Roosevelt pushed a button in Washington, D.

As the celebration got out of hand there was a small riot in the uptown Polk Gulch area. Weeks of civil and cultural activities called "the Fiesta" followed.

A statue of Strauss was moved in to a site near the bridge. In May , as part of the 50th anniversary celebration, the Golden Gate Bridge district again closed the bridge to automobile traffic and allowed pedestrians to cross the bridge.

However, this celebration attracted , to 1,, people, and ineffective crowd control meant the bridge became congested with roughly , people, causing the center span of the bridge to flatten out under the weight.

Official invitation to the opening of the bridge. This copy was sent to the City of Seattle. Since its main span length has been surpassed by fifteen bridges; it now has the second-longest main span in the United States, after the Verrazzano-Narrows Bridge in New York City.

The weight of the roadway is hung from pairs of vertical suspender ropes, which are attached to two main cables.

The main cables pass over the two main towers and are fixed in concrete at each end. Each cable is made of 27, strands of wire. In the s, when the Bay Area Rapid Transit system BART was being planned, the engineering community had conflicting opinions about the feasibility of running train tracks north to Marin County over the bridge.

The review board's report, released in April , concluded that running BART on the bridge was not advisable. Aesthetics was the foremost reason why the first design of Joseph Strauss was rejected.

Upon re-submission of his bridge construction plan, he added details, such as lighting, to outline the bridge's cables and towers. The color of the bridge is officially an orange vermilion called international orange.

The bridge was originally painted with red lead primer and a lead-based topcoat, which was touched up as required.

In the mids, a program was started to improve corrosion protection by stripping the original paint and repainting the bridge with zinc silicate primer and vinyl topcoats.

The program was completed in and it is now maintained by 38 painters who touch up the paintwork where it becomes seriously corroded.

Most maps and signage mark the bridge as part of the concurrency between U. Route and California State Route 1. The Golden Gate Bridge, Highway and Transportation District has jurisdiction over the segment of highway that crosses the bridge instead of the California Department of Transportation Caltrans.

The movable median barrier between the lanes is moved several times daily to conform to traffic patterns. On weekday mornings, traffic flows mostly southbound into the city, so four of the six lanes run southbound.

Conversely, on weekday afternoons, four lanes run northbound. During off-peak periods and weekends, traffic is split with three lanes in each direction.

From to , opposing traffic was separated by small, plastic pylons ; during that time, there were 16 fatalities resulting from head-on collisions.

The bridge is popular with pedestrians and bicyclists, and was built with walkways on either side of the six vehicle traffic lanes.

Initially, they were separated from the traffic lanes by only a metal curb, but railings between the walkways and the traffic lanes were added in , primarily as a measure to prevent bicyclists from falling into the roadway.

The bridge carries about , vehicles per day according to the Golden Gate Bridge Highway and Transportation District.

The western walkway is open only for bicyclists and only during the hours when they are not allowed on the eastern walkway.

Bus service across the bridge is provided by two public transportation agencies: San Francisco Muni and Golden Gate Transit. It opened in , in time for the bridge's 75th anniversary celebration.

A cafe, outdoor exhibits, and restroom facilities are located nearby. Lands and waters under and around the bridge are homes to varieties of wildlife such as bobcats and sea lions.

The District promised that the proposal, which it called a "partnership program", would not include changing the name of the bridge or placing advertising on the bridge itself.

In October , the Board unanimously voted to discontinue the proposal and seek additional revenue through other means, most likely a toll increase.

In addition to FasTrak, the Golden Gate District implemented the use of license plate tolling branded as "Pay-by-Plate" , and also a one time payment system for drivers to pay before or after their trip on the bridge.

Twenty-eight positions were eliminated as part of this plan. Bicycle, pedestrian, and northbound motor vehicle traffic remain toll free.

In March , the Golden Gate Bridge District board approved a resolution to start congestion pricing at the Golden Gate Bridge, charging higher tolls during the peak hours, but rising and falling depending on traffic levels.

In August , transportation officials ended the congestion pricing program in favor of varying rates for metered parking along the route to the bridge including on Lombard Street and Van Ness Avenue.

Most die from impact trauma. After years of debate and an estimated more than 1, deaths, suicide barriers, consisting of a stainless steel net extending 20 feet from the bridge and supported by structural steel 20 feet under the walkway, began to be installed in April As of December , the completion date for the Golden Gate Bridge net was set for Another anemometer was placed on one of the towers.

Starting in June , reports were received of a loud hum, heard across San Francisco and Marin County, produced by the new railing slats when a strong west wind was blowing.

Modern knowledge of the effect of earthquakes on structures led to a program to retrofit the Golden Gate to better resist seismic events. The proximity of the bridge to the San Andreas Fault places it at risk for a significant earthquake.

Once thought to have been able to withstand any magnitude of foreseeable earthquake, the bridge was actually vulnerable to complete structural failure i.

A custom-built electro-hydraulic synchronous lift system for construction of temporary support towers and a series of intricate lifts, transferring the loads from the existing bridge onto the temporary supports, were completed with engineers from Balfour Beatty and Enerpac , without disrupting day-to-day commuter traffic.

Doyle, the president of the Exchange Bank in Santa Rosa and son of the bank's founder, was the man who, more than any other person, made it possible to build the Golden Gate Bridge.

From Wikipedia, the free encyclopedia. Suspension bridge on the San Francisco Bay. California Historical Landmark. Pass-through mode increases the throughput of the data pump, because all of the functionality that looks up object definitions is bypassed.

In most business cases, you should use a data pump. Some reasons for using a data pump include the following:. Protection against network and target failures: In a basic Oracle GoldenGate configuration, with only a trail on the target system, there is nowhere on the source system to store the data operations that Extract continuously extracts into memory.

If the network or the target system becomes unavailable, Extract could run out of memory and abend. However, with a trail and data pump on the source system, captured data can be moved to disk, preventing the abend of the primary Extract.

When connectivity is restored, the data pump captures the data from the source trail and sends it to the target system s. You are implementing several phases of data filtering or transformation.

When using complex filtering or data transformation configurations, you can configure a data pump to perform the first transformation either on the source system or on the target system, or even on an intermediary system, and then use another data pump or the Replicat group to perform the second transformation.

Consolidating data from many sources to a central target. When synchronizing multiple source databases with a central target database, you can store extracted data operations on each source system and use data pumps on each of those systems to send the data to a trail on the target system.

Dividing the storage load between the source and target systems reduces the need for massive amounts of space on the target system to accommodate data arriving from multiple sources.

Synchronizing one source with multiple targets. When sending data to multiple target systems, you can configure data pumps on the source system for each target.

If network connectivity to any of the targets fails, data can still be sent to the other targets. The Replicat process runs on the target system, reads the trail on that system, and then reconstructs the DML or DDL operations and applies them to the target database.

Replicat uses dynamic SQL to compile a SQL statement once, and then execute it many times with different bind variables.

Initial loads: For initial data loads, Replicat can apply a static data copy to target objects or route it to a high-speed bulk-load utility.

Change synchronization: When configured for change synchronization, Replicat applies the replicated source operations to the target objects using a native database interface or ODBC, depending on the database type.

You can use multiple Replicat processes with one or more Extract processes and data pumps in parallel to increase throughput.

To preserve data integrity, each set of processes handles a different set of objects. To differentiate among Replicat processes, you assign each one a group name see Section 1.

Rather than use multiple Replicat processes, you can configure one Replicat in coordinated or integrated mode. Coordinated mode is supported on all databases that Oracle GoldenGate supports.

In coordinated mode, Replicat is threaded. One coordinator thread spawns and coordinates one or more threads that execute replicated SQL operations in parallel.

A coordinated Replicat uses one parameter file and is monitored and managed as one unit. See Section Integrated mode is supported for Oracle versions In integrated mode, Replicat leverages the apply processing functionality that is available within the Oracle database.

Within a single Replicat configuration, multiple inbound server child processes known as apply servers apply transactions in parallel while preserving the original transaction atomicity.
