During a direct path load, the existing index is copied when it is merged with the new index keys. If the existing index is very large and the number of new keys is very small, then the index copy time can offset the time saved by a direct path load.
Also, You should use a direct path load in the following situations: You have a large amount of data to load quickly. A direct path can quickly load and index large amounts of data. It can also load data into either an empty or non-empty table. You want to load data in PARALLEL for maximum performance. Likewise, These include: 1. Use Direct Path Loads- The conventional path loader essentially loads the data by using standard insert statements. The direct path loader (direct=true) loads directly into the Oracle data files and creates blocks in Oracle database block format. Next, To prepare the database for direct path loads, the script $ORACLE_HOME/rdbms/admin/catldr.sql.sql must be executed. - Disable Indexes and Constraints. For conventional data loads only, the disabling of indexes and constraints can greatly enhance the performance of SQL*Loader. In this manner, For example, you can perform a direct path load from a release 9.0.1 database into a release 9.2 database. However, you cannot use direct path load to load data from a release 10.0.0 database into a release 9.2 database. Tables to be loaded in direct path mode do not have VPD policies active on INSERT.

How is a direct path load different from a conventional load?
A direct path load calls on Oracle to lock tables and indexes at the start of the load and releases them when the load is finished. A conventional path load calls Oracle once for each array of rows to process a SQL INSERT statement. A direct path load uses multi-block asynchronous I/O for writes to the database files.
How can i convert windows path to posix path using node path?
This will convert your path to POSIX format irrespective of whether you're already on POSIX platforms, or on win32, while requiring zero dependencies. There is node package called upath will convert windows path into unix. A one-liner mimicking slash and upath (see the multi-liner version for proof of validity)
Which is path to poe-path to path of exile?

What is imposed load, service load, factored load?
IMPOSED LOAD,SERVICE LOAD, FACTORED LOAD. All external loads acting on the member to be designed are called imposed or superimposed loads. It include live load, wind load, earthquake load, etc. Part of dead load may also act as imposed load. The maximum intensity of load expected during the life span of the structure is known as service load.
Which is faster direct path or conventional path?
A direct path load is faster than the conventional path for the following reasons: Partial blocks are not used, so no reads are needed to find them, and fewer writes are performed. SQL*Loader need not execute any SQL INSERT statements; therefore, the processing load on the Oracle database is reduced.
Which is faster, direct path load or bulk copy?
Using direct path load is faster than conventional loading (using conventional SQL INSERT statements). Conventional loading formats Oracle data blocks and writes the data blocks directly to the data files. Bulk Copy eliminates considerable processing overhead.
When to use direct path load in exec?
When you see in the exec plan something like "INSERT into TABLE CONVENTIONAL" then the hint is ignored. If you see "INSERT as SELECT" then you are using direct path load. insert typically looks for the first empty space in your table to add the new record. While this conserves space, it may sometime slow down the operation.
Do you need dml lock for direct path load?
Although a direct path load minimizes database processing, several calls to the Oracle server are required at the beginning and end of the load to initialize and finish the load, respectively. Also, certain DML locks are required during load initialization, and are released when the load completes.
Which is better a direct load or a conventional load?
A direct load does not compete with other users for database resources, so it can usually load data at near disk speed. Considerations inherent to direct path loads, such as restrictions, security, and backup implications, are discussed in this chapter. The tables to be loaded must already exist in the database.
Which is harder the longest path problem or the shortest path problem?
In contrast to the shortest path problem, which can be solved in polynomial time in graphs without negative-weight cycles, the longest path problem is NP-hard and the decision version of the problem, which asks whether a path exists of at least some given length, is NP-complete.
Why is the eightfold path called the noble path?
The eightfold path is the fourth noble truth, the way to awakening. The Buddha is often described as a great physician or healer, and the eightfold path (also called the noble eightfold path, “noble” because following it can make us better people, like the Buddha) can be viewed as his prescription for relief.
When to use path mask and path mask in wincp?
When a mask selects files and it makes sense to select them based on directory, you can extend the mask with a path mask. You should separate the path mask from the filename mask by a slash. For example mask /home/martinp/*.txt matches all text files within the directory.
Why do i need to check if a path exists within a path?
Typically the reason for checking if a path exists within PATH is because you want to append the path if it isn't there. This is normally done simply by using something like path %path%;%newPath%.
How to add path to path in centos?
You can set environment variables in a.rc file; for bash shells (I believe the most common, and default in CentOS) each user has a file called.bashrc in his home directory. Add the command PATH=/usr/lib/ruby-enterprise/bin:$PATH to this file to set it for any one particular user.
When to specify a run path search path?
Specify a run path search path when linking your application. This gives the linker a list of paths to use to resolve any @rpath variables that it encounters in any load commands. If you're copying the libraries to MyApp.app/Contents/Frameworks you'll want to specify a run path search path of @loader_path/../Frameworks.
When to use absolute path or absolute path in devserver?
This is only necessary if you want to serve static files. devServer.publicPath will be used to determine where the bundles should be served from, and takes precedence. It is recommended to use an absolute path. By default, it will use your current working directory to serve content. To disable contentBase set it to false.
When was the critical path institute ( c-path ) launched?
Launched on May 19, 2015, INC is C-Path’s ninth consortium – a global collaboration formed to forge a predictable regulatory path for evaluating the safety and effectiveness of therapies for neonates. Launched in December, 2012, MSOAC is another dynamic partnership formed to promote consensus science.
What's the difference between django.urls.path and re _ path?
So what's the difference between the django.urls.path and django.urls.re_path methods ? The former is used to match simple url patterns, while the latter is used to match more complex url patterns. In addition to this difference, there's also a historical Django perspective for why there are two ways to declare url patterns.
