The notebook is WIN764-bit. I have encountered several problems when installing ORCAL. I believe all the people who have installed it will know about it. But remember it and check it later. Problem 1: After Oracle10g is installed and em is executed, the interface is displayed, but an error is reported: java. lang. Exception: ExceptioninsendingRequest: null is not applicable to many functions.

Problem 1: After installing Oracle 10 GB and then running em, the interface is displayed, but an error is reported:
Java. lang. Exception: Exception in sending Request: null
Many functions are not available, prompting you to log on again
Solution: Find the following file
$ ORACLE_HOME \ db_1 \ $ HOSTNAME \ sysman \ config \ emd. properties
$ ORACLE_HOME \ db_1 \ sysman \ config \ emd. properties
Note: The two paths are different. The agentTZRegion field can be found from the above paths.
For example, my computer is c: \ oracle \ product \ 10.2.0 \ db_1 \ zy_1_l \ sysman \ config
The default value of agentTZRegion is GMT, which can be changed to your time zone. For example:
AgentTZRegion = Asia/Shanghai
For a list of time zones, see 10.2.0 \ db_1 \ sysman \ admin \ supportedtzs. lst.
When modifying a file, stop the following services, copy the file, modify the file, and overwrite the file.
About services
Then stop dbconsole to make the time zone settings take effect and restart OracleDBConsole:
The order is as follows:
Stop dbconsole
Emctl resetTZ agent
Emctl config agent getTZ
Start dbconsole
Question 2:
PLSQL Installation Problems
64-bit win7 installation of oracle reported "ORA-12154: TNS: unable to resolve the specified connection identifier"
The following is a description by a netizen:
Oracle 10g is installed in 64-bit win7, and everything is normal after testing. But after installing PL/SQL Developer 8, enter the missing user name and password, but reported "ORA-12154:
TNS: the specified connection identifier cannot be resolved ". Check that the configuration files tnsnames. ora and listener. ora are correct. I checked the reason on the Internet and said, "It's because of environment changes.
PL/SQL does not find the configuration file, so environment variables are configured, but an error is reported. The other is the problem with the configuration file. I began to go astray and conduct the configuration file
All kinds of modifications, but it still does not work. Why is it so strange? It should be said that there is no problem ~ I installed a lower-green PL/SQL version. The connection is successful. Strange ~ Not installed before
Found this problem! Go online and check again. I found an article with the same problem in the "chewinggum's column". I carefully checked his solution and followed it. Set
The PL/SQL Installation File is uninstalled, re-installed, and installed in the specified directory without selecting the default "Program Files (x86)". After the installation is successful, connect,
OK ~ Very helpless! Originally, 64-bit win7 installed 32-bit applications under the Program Files (x86) directory by default, and these two parentheses may cause conflicts.
It's really killing people ~ You must install the software that needs to connect to oracle later. The problem is finally solved. Thanks to chewinggum, Hu Ge, and Xiao Chen.
I have to unload the CR and reinstall it again. Be sure to choose a comfortable place to rest it, or it will have to make trouble with me.
I tried all the above methods, and then used the reinstallation to solve the problem by changing the file name.
PS: I have always wanted to learn OrCL. I met this project and simply installed it to build a real environment, BLESS!
