If set, the timestamps of the listed readings will not be changed if event-on-change-reading is also set and it would not create an event for this reading.
The precedence of event-on-update-reading and event-on-change-reading is as follows: See below for alternative way to specify the username and password. It defines a set of methods, variables, and conventions that provide a consistent database interface, independent of the actual database being used.
There are many wifi dongles and most of them are very bad poor signal quality. When running under DBI:: Connectivity Of course, the first thing you need is proper connectivity, especially if you have your RPi on a remote location. You may use regular expressions for reading. Test Modules Core tests: If both attributes are not set, any update of any reading of the device creates an event.
I can also update the article to include more info. When using regexps in the usr part with wildcards, the fw part must be filled with the exact same keys to enable a correct display in the FHEMWEB set dropdown list in the detail view. It supports a few options, one in particular: The DBI provides a standard interface and framework for the drivers to operate within.
GnuCOBOL is poised to change that historic trend, and allow for the long overdue sharing of wisdom that legions of COBOL developers have accumulated over 50 years of success and failure.
After the black-out period has expired, the reading is updated with a value that is calculated from the values and timestamps of the previously ignored updates within the black-out period as follows: Select OutFile Assign to "C: You can reduce network traffic by using a dataset that caches updates locally and applies them all later in a single transaction.
Instructions for use of the NIST suite is included in the build archive under: So why move away from the BDE? This can cause problems, especially with the AutoCommit attribute. Now run your apt-get etc stuff, modify what you need. Proxy documentation for more details.
It is up to the driver implementors to decide how they wish to handle such binary data. It provides a simplified framework for data access based on OLE DB, the real power horse behind the scene.
Be careful not to overwrite additional global attributes previously defined by yourself or a device. This is used to further group devices together. Unlike the BDE, dbExpress returns only unidirectional cursors and therefore does no caching. The Execute method is very convenient for executing simple SQL statements that do not return any records.
This determines whether changes are automatically committed to the database when executed, or need to be explicitly committed later.
The above will output: This application requires high reliability and it was a pretty long journey until all the issues were solved. I made my own script for this purpose, though.
I have been using 5 RPis as a camera with motion detection and post-processing. I can also update the article to include more info. But first… even if you have your FS read-only, a cheap SD card can destroy the data on the card itself. DHCP lease is the major problem. After the black-out period has expired, the reading is updated with a value that is calculated from the values and timestamps of the previously ignored updates within the black-out period as follows: For information on the advantages of using client datasets to cache updates, see Using a client dataset to cache updates Client datasets can apply edits directly to a database server when the dataset is read-only.
You can reduce network traffic by using a dataset that caches updates locally and applies them all later in a single transaction. However, the everyday use of these environment variables is not recommended for security reasons.
The attribute takes a comma-separated list of readings. What to do next Enjoy your reliable RPi. By default, other types of datasets post edits directly to the database server. In other words, if you have no user interface, you probably do not need a DataSource.Library¶.
bpo Fix regression in number of arguments compileall accepts when ‘-d’ is specified. The check on the number of arguments has been dropped completely as it. Please note that Tim Bunce does not maintain the mailing lists or the web page (generous volunteers do that).
So please don't send mail directly to him; he just doesn't have the time to answer questions personally.

Yes, that is one possible cause. Where is your working copy located (local disk, network share, etc.)? Are you running an on-access virus scanner and if so, which one? Analyses 🔬 Spike Demand Pool Comparison. Analysis of HikariCP v, in comparison to other pools, in relation to a unique "spike demand" load.
The customer's environment imposed a high cost of new connection acquisition, and a requirement for a dynamically-sized pool, but yet a need for responsiveness to request spikes.Download
