ERROR: The provided repository type was not detected in the current directory.

When creating diff using 'rbt post' for review board with perforce client, reported issue occurs as below. This can be solved by verifying the client root in p4client and the path from where the rbt post command issued must be the same.

• When I try to launch the Internet Explorer 11 via Selenium RC server, faced with the below pop.
• After surfing found attachEvent is a deprecated function used in older versions of Internet Explorer and modern browsers use addEventListener instead.
• So if you are using earlier version of Selenium server try using the latest selenium standalone server. Which will solve the reported pop up issue.

couldn't open app window; is the pop-up blocker enabled

When I try to launch the Internet Explorer 11 via Selenium RC server, faced with the below pop.

After marking the pop up blocking to be turned off and disabling the “Enable protected mode settings” under security tab, the reported issues got resolved. Please find the helpful screen shots.

Unexpected error in launching a slave. This is probably a bug in Jenkins

Launching a slave agent in Jenkins could result in the below error. This occurs when adding a Linux machine as slave node in Jenkins. Here ssh connection to the Linux server fails.

One instance where this could be corrected is to enable the publickey authentication in the linux server.

Few steps to do so are as below,

• Edit the sshd_config file under /etc/ssh to modify the parameters, here we enable the publickey authentication and authorisedKeys.

• After modifying the file to take effect restart sshd service

• Then relaunch the slave agent which should be successful.

Password field value entered twice on using selenium webdriver

While running webdriver script to login to webpage by provide the username and password credentials, you may notice that the password field is actually entered twice once you enter the username and then entering the password.

The reason is when you have logged in before via manually/script and if the auto save feature of user name and passwords are enabled and saved this may occur.

If Auto save feature is enabled for username and password, after entering the username via script and tabbing out to enter the password itself put the saved password.

Here the password is 7 characters, but 14 characters has been updated.

Password typed twice

Solution:

1. Remove the auto save of user name and password feature at browser level
2. Or do a clear on the fields before entering the values.
 

The method sendKeys(CharSequence[]) in the type WebElement is not applicable for the arguments (String)

When using sendKeys on an web element using selenium, the reported exception may be thrown as below.

This can be corrected by changing the java compilation level tot he latest availabe verison in eclipse.
Project propeties > Build Path > configure Build Path > Java compiler > compiler compilation level (Change to latest available version).

The protected mode setting in internet explorer must be enabled for all zones listed under the security tab on Internet Options menu.
Correcting it to have the setting enables would solve the above reported issue.

ORA-01119: error in creating database file

After dropping tablespace with including contents, may end up with "ORA-01119: error in creating database file".

Reasons could be
1. Not deleting the datafile with "INCLUDING CONTENTS AND DATAFILES"
2. Provided directory path does not exist
3. Error accessing the directory (read/write permission or misspelling of directory names)
4. Datafile already existing in the current directory

Here is the case with not deleting datafile with drop tablespace,

Tablespace dropped.

Exception in thread "main" java.lang.IllegalStateException

When executing a selenium script written in java to use IE/Chrome driver, an exception would have been thrown to check System.setProperty. The code below seems to be exactly right but 'webdriver' is coded as 'Webdriver' in the first argument, and there stands the exception.

File file = new File("G:\\Data\\git\\Test\\lib\\IEDriverServer.exe");
System.setProperty("Webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();

This can be corrected by having the pull path of the url as below


Change:
WebDriver driver = new FirefoxDriver();
driver.get("www.gmail.com");

To:
WebDriver driver = new FirefoxDriver();
driver.get("http://www.gmail.com");

Insert string with apostrophe(') in sql

when using Insert statement to inset string type fields and the values has an apostrophe('), how

the inset statements can be handled in such cases.


SQL> insert into donuts values('jelly's,9);
insert into donuts values('jelly's,9)
                                   *
ERROR at line 1:
ORA-00917: missing comma


SQL> insert into donuts values('jelly''s,9);
ERROR:
ORA-01756: quoted string not properly terminated

The Error displayed here is due to string data types that are delimited by the single quotation mark and the apostrophe(') is considered as the end of the string  delimiter.

The possible way is to escape single apostrophe (') with an extra apostrophe as below.


SQL> insert into donuts values('jelly''s',9);

1 row created.

Now the string with apostrophe is inserted into the table.

SQL> select * from donuts;

NAME	PRICE
----------	----------
jelly	9
jell's	9

This should be solved on using the latest java versions.
