Persistent notifications are notifications that stay visible on your device even after you’ve interacted with them, rather than disappearing as soon as you clear them. They typically appear as small icons in a notification bar or an area at the top of your screen.
They’re typically used to remind you of something or to provide ongoing updates about a particular service or activity. For instance, many music streaming apps will feature a persistent notification when the app is actively playing music.
Other common uses for persistent notifications include alerts for low battery or data usage thresholds, alarms, and incoming messages and emails. They can also be used to keep you up to date with tasks, like a to-do list or a recurring reminder.
Persistent notifications are generally easier to view and interact with than regular notifications which can easily be missed, so they can be a great way to help stay organized and alert.
What is difference between persistent and non persistent?
The main difference between persistent and non-persistent connections is that persistent connections are established and maintained while non-persistent connections are opened and closed with each request and response.
Persistent connections are used to create a long-term, open connection between a client and a server, allowing multiple requests to be made on the same connection. Non-persistent connections, on the other hand, use a separate connection for each request, which is then closed after the response is returned.
Persistent connections are more efficient as they allow for improved performance and less network overhead. This is advantageous in applications, like web browsing, that require a high rate of data exchange.
As persistent connections use the same connection for multiple requests and responses, there is less need for time-consuming tasks, like the establishment of new connections, which would typically be done for non-persistent connections.
Non-persistent connections, however, are typically more secure. As each connection is established and then closed, it is less likely to be successfully attacked by malicious actors. It is also useful if the server has limited resources, as each connection is established and removed as needed.
In summary, persistent connections are used to create a long-term, open connection between a client and a server, allowing multiple requests to be made on the same connection, reducing network overhead and improving performance, while non-persistent connections are established and closed with each request and response, providing more security in the face of malicious actors.
Should banner style be temporary or persistent?
When it comes to banner style, it can depend on the specific context and preferences of the user. Generally, when it comes to web design, a banner should have a persistent style in order to maintain a consistent user experience.
This means that the banner should stay the same throughout the navigation and user flow, so that there is a sense of coherence in the design. At the same time, there may be moments when a temporary style may be beneficial, such as when you want to notify users of specific functions or updates.
In this case, a temporary style announcement can be used to draw attention and build awareness without disrupting the current design. Ultimately, it is important to consider the context and user expectations for the website when it comes to deciding between a temporary or persistent style for the banner.
What is a temporary banner on iPhone?
A temporary banner on iPhone is an alert or notification that appears at the top of your screen while you are using your iPhone. It is usually used to provide information to the user, such as an alert about an incoming call, a reminder to schedule an event, or to let you know that an update has been downloaded.
The banner appears briefly and then disappears. You can tap the banner to open and take action on the notification. With multiple notifications, banners stack and can be swiped left or right to view all of them.
Temporary banners are a mechanism to inform and remind the user about important information or activities related to their apps and devices.
Do cheaters silence notifications?
Yes, cheaters can and often do silence notifications in an attempt to avoid detection. They may do this from their partner’s device, though it’s more common to happen from the cheater’s own device. Cheaters who are using a dating app or website, for instance, can easily turn off notifications so that they are not alerted when they receive messages.
If a person is engaging in inappropriate conversations with someone else, it is unlikely they will want to be alerted when someone is trying to get ahold of them. By silencing notifications, the cheater can keep their activities private and can avoid detection.
Cheaters may also silence notifications on their partner’s device to avoid being caught. As with their own device, a person who is cheating can easily go into their partner’s device settings and turn off notifications that alert them of incoming messages or emails.
This would stop suspicions from arising from their partner seeing notifications from an unknown person.
While silencing notifications is an effective way for a cheater to avoid detection, this is not foolproof. Smart partners can often tell when notifications have been silenced and this can create even more suspicion.
Additionally, many people analyzing their partner’s online activity will take note of whether notifications have been silenced and this can be a huge red flag.
What does it mean when someone has notifications silenced on iPhone?
When someone has notifications silenced on their iPhone, it means that they have chosen to mute the notifications for certain apps or contacts. This means that when they receive notifications from these apps or contacts, they will not receive any sound alerts from their phone.
However, the notifications will still appear in the notification center. Silencing notifications can be a useful way for someone to be able to focus and concentrate without their phone constantly going off with alerts.
Are message queues persistent?
Message queues are generally persistent, meaning that the messages placed onto the queue are not lost when the system restarts. This is useful for a variety of applications, as it allows the system to remain robust and better able to handle transient errors.
For example, if the system encounters a fault and shuts down, the message queue will be able to provide the necessary information to restart it. This can improve recovery times, leading to greater efficiencies and improved system performance over the long-term.
Additionally, persistent message queues also offer better fault-tolerance as any messages placed on the queue will be recovered when the system restarts. In some cases, messages may also be stored on an external drive or backup device to further improve data recovery.
Which type of messages survives when a queue manager stops responding?
When a queue manager stops responding, messages that are stored in the queue and have not been processed yet will survive the outage. These messages are commonly referred to as “in-flight” or “in-transit” messages.
These messages will not be affected by the outage and will remain in the queue until the queue manager is able to resume operations. Once the queue manager is restarted, the in-flight messages will be processed as normal.
It’s important to note, however, that any messages that had not yet been sent to the queue prior to the outage will be lost, as they were not stored in the queue at the time of the outage.
What is the maximum queue depth in MQ?
The maximum queue depth in IBM MQ is determined by the queue depth attribute, which specifies the number of messages that can be stored in the queue before the system stops accepting new messages. The maximum queue depth attribute is set either by the system administrator or by an application program.
The specific value is determined by the system and can be changed as needed. Generally, the maximum queue depth is set to the highest value that will allow the queue to perform efficiently without consuming excessive system resources.
In modern versions of MQ, the default queue depth is defined as 5,000 messages. However, the maximum queue depth is configurable and can be set as high as millions of messages. It is important to remember that increasing the queue depth can adversely affect performance due to increased memory usage.
Therefore, the system administrator should consider the specific requirements of the applications that are using the queue when configuring the queue depth.
What happens when MQ queue is full?
When an MQ queue is full, messages cannot be put on the queue until the process that is consuming messages processes them or the queue is emptied. Depending on the type of queue and the queue manager configuration, this can mean that new incoming messages must wait in a different queue or they can be discarded without being processed.
Additionally, when the number of messages exceeds the defined limit of the queue, the queue manager may send an alert or perform an automatic action on the queue, such as stopping the queue, automaticly deleting messages, or sending an alert notification.
What is a good queue depth?
A good queue depth is the number of I/O operations that can be queued up in a storage system before being processed. The optimal length for a storage system queue will vary depending on the type and size of the system and the types of tasks that it is being used for.
Generally speaking, a good queue depth is one that is large enough to handle the highest load that the system is expected to experience while reducing latency. If the queue depth is too large, it may lead to too much idle time and wasted resources on the storage system, while a queue depth that is too small may lead to bottlenecks and slowdowns during periods of peak usage.
Queue depth should be adjusted according to the workloads and system performance benchmarks to ensure the optimal usage of resources.
How do I check my MQ queue depth?
To check your message queue depth, you need to use the MQSC command DISPLAY QSTATUS.
The command syntax is DISPLAY QSTATUS(QName) where ‘QName’ should be replaced with the actual name of the queue that you want to check.
Once you have entered the command, the results will include the current queue depth. For example, for queue ‘Q1’, you would enter: DISPLAY QSTATUS (Q1)
The result would look something like this:
AMQ8409: Display Queue Status details.
QUEUE(Q1) TYPE(QLOCAL)
CURDEPTH(2)
In this example, the depth of the queue is 2.
If you want to check the depth of all queues on your system, you can use the wildcard DISPLAY QSTATUS(*) which will display the depth of all queues.
