Demantra setup.exe does nothing on Windows 7

Last evening, Mukhtiar called me to assist in Demantra installation on Windows. By the time we got on screen share, he had already downloaded patch 2195481 and installed JDK 1.8.0_77. However, when he clicked setup.exe, nothing happened.  We tried these :

We are currently upgrading one of our ERP instances from to R12.2.5.  One of the pre-upgrade steps is to execute the data fix script ap_wrg_11i_chrg_alloc_fix.sql.  However, this script has been running very very slow.

sftp failure due to newline character difference between windows and unix.

Recently I spent almost a full day struggling to make out, why an sftp connection would not work without password, after setting up ssh equivalence.  The keys were correct, the permissions on the directories were correct.  The authorized_keys file looked ok.  I copied the authorized_keys file of another account that was working fine.  When I replaced the authorized_keys after taking backup of original authorized_keys, it started working.  So then I proceeded to check the contents (more...)

Copycat blog

While doing a google search today I noticed that there is another blog that has copied all content from my blog and posted it as their own content and even kept a similar sounding name: .  I have made a DMCA complaint to google about this.  I will update this article about how it goes.

Server refused public-key signature despite accepting key!

A new SFTP connection was not working, even though everything looked fine:

chmod 700 $HOME/.ssh
chmod 600 $HOME/.ssh/authorized_keys
chmod 600 $HOME/.ssh/id_rsa
chmod 644 $HOME/.ssh/
chmod 644 $HOME/.ssh/known_hosts

2. Keys were correctly placed

However, it still asked for password, whenever SFTP connection was done:

Using username "sftpuser".
