Suse Update by using YAST

Yazar: enes koc Kategori: Unix/Linux
  • Start the Online-Update module (YOU) from the YaST control center.
  • Press ‘Accept’ to apply updates with ‘package management’ flag set. Among others, this will install a libzypp maintenance stack update (Patch ‘slesp2-libzypp’ / ‘sledp2-libzypp’). After installing those, YOU will restart itself.
  • Press ‘Accept’ to apply all available updates that are available for SP2. This may also install a new kernel, so you should reboot the system after applying this one.
  • Start the Online-Update module from the YaST control center again.
  • Select the optional “Update to SUSE Linux Enterprise Server/Desktop Service Pack 3” (‘move-to-sles10-sp3’ / ‘move-to-sled10-sp3’) patch. Do not select any other patch at the same time – except for for additional migration patches for add-on products. If an add-on product (e.g. the SDK) is installed, the respective migration patch will be selected automatically. The migration of the add-on product should be done at the same time as the base product, otherwise there would be rpm dependency conflicts.
  • After the patch is installed, YOU will close.
  • Start the Online-Update module from the YaST control center again.
  • Amongst others patches, ‘slesp3o-sp3_online’ and ‘product-sles10-sp3’ (or ‘sledp3o-sp3_online’ and ‘product-sled10-sp3’ accordingly) are preselected. Apply these patches to bring the system to SP3 level.
  • Reboot the system.

Search folder in jar file example:
find folder -name ‘*.jar’ -o -name ‘*.war’ -o -name ‘*.ear’ -type f | xargs -i bash -c “java path -tvf {}| tr / . | grep searched data && echo {}”

find /opt/WebSphere60/PortalServer/ -name ‘*.jar’ -o -name ‘*.war’ -o -name ‘*.ear’ -type f | xargs -i bash -c “/opt/WebSphere60/AppServer/java/bin/jar -tvf {}| tr / . | grep EDataObjectHbtrImpl$EDataObjectExternalizable && echo {}”

Search a word in gzip files without extract example :
zcat compressed folder | grep -i searched data | wc -l
zcat SystemOut.log.gz | grep -i Enes | wc -l

Firstly you should add secondly disc .The secondary disk is 1GB in this example. 

Run YAST on SUSE  (YAST>system>partitioner):

Create primary partition :

Add new device  in used volume group using add volume

Certificate Management:

SSL Certificates expiration monitoring for WebSphere or any java based application server using java keystore
If you are a WebSphere Administrator or any Application Server (WebLogic, Tomcat) administrator you might already know that managing the ssl certificates in a large complex environments becomes hectic and troublesome because of the different expiration dates of the certificates that websphere uses and also the ssl certificates of the external systems (like SAP , Siebel) that websphere applicaton server might connect to using a secure connection, multiple administrators in an organization renewing it and not keeping tracking of the expiration dates. The problem is , SSL certificate might expire resulting in servers will not initialize and your running servers will stop operating, becomes unresposive if not properly renewed on time. Hence this article will explain how you can monitor the expiration of the ssl certificates using a simple command and proactively monitor the expiration dates, setup your calendar and renew it on time to prevent any downtimes.

1) find text in the matching files and show the filename with the pattern. The below example shows the list of filenames and the location of the hostname in those files, which will be helpful when changing hostnames for your websphere installation.

find . -name ‘*.xml’ -print | xargs grep ‘hostName’ /dev/null

bash-2.05b# find /usr/IBM/WebSphere/AppServer/profiles/AppSrv01/config/ -name ‘server*.xml’ -print | xargs grep ‘hostName’ /dev/null | more
