Today i receive a disk full alarm from my portal server. As usual i delete some logs and files left behind, but for this time this does not solve the issue.

Search for big files or what folder is bigger on linux is hard using du. Googling i found a nice toll and what i found was a big surprise.

I setup NCDU (NCurses Disk Usage) is a curses-based version of the well-known “du”, and provides a fast way to see what directories are using your disk space.

The setup is easy:

1 - yum install ncurses-devel ncurses

2 – download ncdu

3 – untar the file

4- ./configure –prefix=/usr

5 – make && make install

To run just type ncdu at / and the tool will scan your entire server.

Navigating on the toll i found a big folder inside of the connections portlets called “logs” full of files 5GB. The path on my server is :

/opt/IBM/WebSphere/wp_profile/installedApps/portalCell/PA_icWEFPtlts.ear/snor.pf.portlets.war/WEB-INF/logs

I check my server and no tarces are on.

Why these logs are there? I don’t know yet.  I just clean my server.

NCDU did the trick !  Thanks.

Yesterday i was installing a TSM Server for our company. The db2 installer complain about the /tmp size.

The installer need 2,5GB and my /tmp has only 2 GB.

I create a “disk” using dd command with 4GB on a partition with lots of space.

dd if=/dev/zero of=/usr/tmpDSK bs=1024k count=4096
mkfs -t ext3 /usr/tmpDSK
file /usr/tmpDSK
umount /tmp

mount -o loop,exec,nosuid,rw /usr/tmpDSK /tmp

After the db2 installation i umount the /tmp and mount it back using fstab -a

Some administration features that are available in an on-premises Lotus Domino environment are unavailable, are implemented differently, or have limitations within the SmartCloud Notes service.

It is very important to know this differences.

Today i can’t open the TDI Configuration Editon on one of my servers.

One dialog box appears with the error ” Review the .metadata\.log for details.”

To solve the problem:

Go to the <workspace>/.metadata/.plugins/org.eclipse.core.resources/ directory.

If there is a .snap file, then delete or move to different location.

Setup SSO with Windows Desktop is not so hard. But when things is not well documented you can get a big headake.  A customer ask to implement this SSO. The environment was a WebSphere Portal V.8.0 cluster and the user repository was AD 2012.

I setup the system following several documents from IBM and other blogs.  The SSO just not work.

Searching a log for one  solution i found the following:

DES Encryption and Kerberos Authentication:
Starting with Windows Server 2008 R2, domain controllers (and domain members) will no longer allow DES encryption for Kerberos tickets. DES encryption was cracked last millennium, so it’s time to move on to better encryption mechanisms like AES.

http://blogs.technet.com/b/askpfeplat/archive/2013/06/03/upgrade-active-directory-to-windows-server-2012-phase-1-assessment.aspx

The solution was simple:

Before AD 2008  the keytab generation was:

ktpass –out appserver1.keytab –princ HTTP/[email protected] –mapuser wastest –pass password -ptype KRB5_NT_PRINCIPAL

For AD 2012 the keytab command line must include the encryption type other than DES and one supported by WebSphere V8.0.x.

I use the following:

ktpass –out appserver1.keytab –princ HTTP/[email protected] –mapuser wastest –pass password -ptype KRB5_NT_PRINCIPAL -crypto RC4-HMAC-NT

The RC4-HMAC-NT did the trick.

This document show the step by step i follow.
