How to reproduce “resource busy and acquire with NOWAIT specified or timeout expired ” error on local machine in oracle

I am running oracle database and I am getting error as "resource busy and acquire with NOWAIT specified or timeout expired " and because of this error i am getting some other exceptions. on my local machine I am not getting this "resource busy …" error. basically I want to reproduce this error on my local machine . is there any way to reproduce this error manually on my local machine?

How can I get LOAD DATA LOCAL INFILE to work for MySQL 8.0.21 on a Windows machine?

I’ve created a file: 'C:\fff.txt' which contains data for my database table. Then I’m trying to load data from that file like this:


but I get the following error all the time:

ERROR 2 <HY000>: File 'C:\fff.txt' not found (OS errno 2 - No such file or directory) 

I’ve added local_infile=1 to [mysql] and [mysqld] sections of my.ini file. When I type: SHOW GLOBAL VARIABLES LIKE 'local_infile'; I can see that it’s set to 'ON'. Is there a way to solve this problem?

How important is initial state for local search optimisation?

I have been enjoying Pascal van Hentenryck’s Discrete Optimisation course and we’re in Week 4 on the wonders of Local Search algorithms for combinatorial optimisation.

I’m wondering how important the initial configuration is to the quality of solution achievable in a fixed time or, somewhat equivalently, how quickly a solution of a given quality can be reached.

So if I have a good heuristic or intuition for how to arrange things in the first place, is it helpful to devote some processing time to setting that up or is it all dominated by the effect of the local search process?

For example, in the Cartesian Travelling Salesman Problem (where we’re working in a 2D plane and the cost of a journy is simply the straight-line distance) I might "feel" that a good route could roughly follow a clockwise sweep from the centre of the space. So I could use this to set my initial tour (i.e. order the nodes by their angle from the mean of all points). This intuition might be rubbish for certain instances and great for others, I was hoping to see a study where (let’s say random TSP) instances had been solved by following a heuristic first state as opposed to a completely random (but legal) first state.

/wp-admin not accessible after migrating to local host (no plugin issue)

I migrated my local WordPress site to my WPEngine account and it’s been working without any problem!

After adding some content, I decided to export the database from the live version and import it to my local version so that they are synced. I adjusted the two siteurl and home fields in the database and the home page (https://localhost:8888) comes up well but the /wp-admin page is forced to https and responds with ERR_SSL_PROTOCOL_ERROR error.

All the other pages of the website cannot be loaded and return this error: Not Found The requested URL /news was not found on this server.

It seems like a "permalinks" reset problem for inner pages!

All these problems would go away if I switch the database back to the one I was using for local version so I’m pretty sure it’s a database issue!


Getting the hostname of devices in the local lan

I’m trying to get the hostnames of devices on my LAN.

This network is not a Windows network.

Up until now I was able to sniff DHCP requests and extract the hostname from there, but it looks like Android devices starting from Android 10 stopped filling out that particular field.

(I’ve also tried sending a netbios query)

Is there another way to coerce devices to tell me their hostnames?

Problems with using a non-reserved top-level domain for local DNS resolution

A network administrator at my organization (let’s call him "Bill") wants to configure an internal DNS with the live top-level domain (TLD) .int for internal IP address resolution (for Active Directory, internal websites, etc.). For example, the domain would resolve to the some internal site that isn’t visible to the public. Our organization has not registered these domain names with a registrar. Now I know that this is bad practice, but Bill remains unconvinced that this shouldn’t be done.

What are the problems with using a live top-level domain for internal name resolution? Specifically, what are the security implications? In addition, does this somehow conflict with some fundamental way on how DNS and name resolution is supposed to work?

Note: I originally asked this question on Network Engineering SE and was kindly referred over to this site as a better place for this question.

Metasploit unable to get local issuer certificate

I got the following versions: Framework: 5.0.86-dev Console: 5.0.86-dev

The os that metasploit is installed are windows 10.

I get a meterpreter session with an android device (genymotion virtual machine) device and desktop are on the same network and also device has enabled gps with pre-defined lat & long and when I enter the following command in meterpreter:

run post/multi/gather/wlan_geolocate APIKEY=my google map API key (clean, without quotes or anything else) GEOLOCATE=true

I get the result in the photo with the error as I describe in the title, does anyone know if its a version SSL problem or something? how and where to search to fix this problem?
