Glance on UNIX

I have used the "glance" utility on HP-UX and Linux systems for quite a while now to get visibility of system resources utilisation. But it's only recently on a quieter-than-normal Friday that I learnt a little more about how to use it.

Type "?" and you get a great menu and then there are all sorts of ways of digging down.

Standard Page Up/Down buttons help you in most screens.

Generally it's simple to navigate and can help you view hardware utilisation and, importantly for me, identify bottlenecks during IT projects.

Hope this is of help to someone else as well - just type "?" in glance and get a little better acquainted with a good tool.

ORACLE: finding tables with LOBSEGMENTS in them

I'm prepping to migration a SAP system on an ORACLE database
As part of this I find that some of the biggest segments in the database are LOBSEGMENTs
How do you find what table they are part of?

select table_name from dba_lobs where SEGMENT_NAME=’’;

Hope that comes in handy...

SAP SCN Blogging running in parallel

Just a quick first 2013 post to mention that I am now utilising SAP SCN blogging in order to be more closely tied into the SAP professional community - I will post more general thoughts on here and link together for any few who may stumble across my blogs.

Moving from SM36/37 to an external job scheduler

Recently I'm pre-occupied by using external job schedulers to control SAP batch jobs in a IT landscape with multiple SAP systems.

My current thoughts turn to security between business functions and to a new way of managing jobs.

First Security - by introducing a central point of control you also introduce a new aspect to Security. If all your jobs are controlled from a central system then you need to be able to group and secure them so that you comply with industry rules for segregation of roles. In many tools this is possible but it can get complicated - keeping an eye on how to architect this for best fine-control and trying to keep as much logical simplicity implicit in the design is a real thinker...... Have you come across the same?

Secondly job management.... with integration with SAP Solution Manager you can start using "Job Documentation" in SolMan - this is a great way to control job management, but now you have the possibility of jobs starting in QA and being controlled in promotion through to Production. This is a massive paradigm shift from the old ways, where unless you built a method for control externally, essentially many people just manage jobs independantly in every system. Is this new overhead entirely worthwhile? Is the cost of administration worth the reduced cost in identifiying the nature of a job? In the end it probably is in most medium to large businesses, but it's something that's hard to quantify.


Expect more ruminations in this areas.....
