PLSQL Startup Error: Initialization error [How to Solve]

preface

After the computer reinstalls vs2022, start PLSQL, and an error is reported, indicating that initialization failed

1. Solution

I installed client 12.2. I found that it requires Microsoft Visual Studio 2013 Redistributable on the official website. After vs2022 upgrade, this toolkit is lost.

Solution:
after downloading Microsoft Visual Studio 2013 redistributable, install it. (you need to uninstall the higher version first)
download address:
64 bit: vcredist_ X64
32-bit: vcredist_ x86

[Solved] vivado Install Error: Xilinx Design Tool Display in Red

Vivado installation error: Xilinx design tool, already exists for 2019.2, specify a different program program group entry

Reason for error: vivado has been installed, and Xilinx Design Tools folder already exists

Solution: find the “Xilinx Design Tools” folder and delete it
Xilinx Design Tools folder path: C:\USER\USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs

 

[Solved] Linux C++ Compile Error: c++: internal compiler error: Killed (program cc1plus)

Compilation error:

make[2]: *** [src/CMakeFiles/goya-rpc.dir/rpc_server_impl.cc.o] Error 4
make[1]: *** [src/CMakeFiles/goya-rpc.dir/all] Error 2
make: *** [all] Error 2

The reason for the error is that the compiling machine is running out of memory, and a large number of template extensions need enough memory.

1.ps aux --sort -rss
2.free -m
3.top  Press [shift + M keys] to arrange them in reverse order

Solution:

You can solve this problem by temporarily using swap partitions:

=[step 1: operate as follows]=========================================

Sudo DD if=/dev/zero of=/swapfile bs=64m count=16
\count is the size of the increased swap space. 64M is the block size, so the space size is bs*count=1024mb
sudo mkswap /swapfile \

=[step 2: close release] ==================================================================================

Sudo swapoff /swapfile
sudo RM /swapfile
then continue to perform your relevant operations…

Note: if you still prompt “g++: internal compiler error: killed (program cc1plus)” after creating the temporary space, it may be because the allocated space is not large enough. You can continue to allocate more space.

How to Solve Azkaban error (Reasons & Solutions)

Error 1: azkaban job Preparing
Solution:
modify the configuration of web-server conf/azkaban.properties
# execute host filter configuration, remove MinimumFreeMemory
# MinimumFreeMemory filter will check if the executor host will have more than 6G of free memory, if less than 6G, the web-server will not send the task to that host
azkaban.executorselector.filters=StaticRemainingFlowSize,CpuStatus

Error 2: When the job is running，azkaban web Error: Free memory amount minus Xmx (2836204 – 0 kb) is less than low mem threshold (3145728 kb), memory request declined

Solution:
[root@qphone02 executor]# vi ./plugins/jobtypes/commonprivate.properties
# set execute-as-user
execute.as.user=false
memCheck.enabled=false  # add memory check is off, otherwise it will report error: less than 3G

[antdv: DatePicker] `value` provides invalidate moment time. If you want set empty value, use `null` 

[antdv: DatePicker] `value` provides invalidate moment time. If you want set empty value，use `null`

Always encounter this problem

Normal use:

html：
 <a-month-picker v-model="monthValue"  :allowClear="false" type="month" placeholder="选择月"></a-month-picker>
data:
monthValue：moment().format('YYYY-MM')

Reason:
ant design vue datepicker needs the format of moment by default, so an error will be reported.

Solution: use following method to define the data:

 monthValue: moment(new Date(), 'YYYY-MM')

Sophus Library Issues (Reasons & Solutions)

This blog records the errors encountered in the process of using sophus.

1. Cannot find header file fatal error: sophus/SO3 HPP: no such file or directory

1.1 problem description

fatal error: sophus/so3.hpp: no such file or directory

Reason:
GitHub is now a new version of sophus, which is based on the template class, and its corresponding header file is .h, while the header file corresponding to sophus based on non-template class is .hpp, so an error will be reported.

1.2 solutions

Put in the code

#include "sophus/so3.hpp"
#include "sophus/se3.hpp"

sophus::sophus SO3d;
sophus::sophus SE3d;

Change all to

#include "sophus/so3.h"
#include "sophus/se3.h"

sophus::sophus SO3;
sophus::sophus SE3;

2. /usr/bin/LD: not found - lsophus:: sophus

2.1 error reporting prompt

Compilation error

/usr/bin/ld: Could not find -lSophus::Sophus
/usr/bin/ld: Could not find -lSophus::Sophus
collect2: error: ld returned 1 exit status

2.2 solutions

My original cmake:

list(APPEND ALL_TARGET_LIBRARIES ${Sophus_LIBRARIES} Sophus::Sophus)
target_link_libraries( useSophus ${Sophus_LIBRARIES} Sophus::Sophus)

Modify to

list(APPEND ALL_TARGET_LIBRARIES ${Sophus_LIBRARIES})
target_link_libraries( useSophus ${Sophus_LIBRARIES})
