New features in SAP Sybase ASE 15.7 ESD#2

August 23rd, 2012 No comments

Really very Good and useful new features in Sybase ASE 15.7 ESD#2, Checked Out in Rob’s Blog :

 

A few weeks ago (early August 2012), ASE 15.7 ESD2 was released. Despite being an ESD, this ASE release actually contains a truckload of great new features as well. You should really check these out since some of these are just so useful… Let me just highlight a selected few that I like particularly (I hope to come back to some of these topics in the time ahead).

* larger database size – First, the maximum size of an ASE database has been doubled as of 15.7 ESD2. This means that with a 2KB or 16KB page size, the maximum size of a single ASE database is now 8TB or 64TB, respectively (and you can still have thousands of such databases in a single ASE server).
* async database creation
* split/merge partition
* non-blocking table rebuild
* faster update statistics
* faster index creation
* query performance
* Materialized Views
* security & permission

dbcc checkdb vs dbcc checkstorage

June 25th, 2012 No comments

Checkstorage will detect allocation errors, it is a reasonable substitute for dbcc checkalloc (checkstorage will report a fair number of issues that checkalloc will not, many of them trivial things, and checkalloc may be able to detect a few odd conditions
checkstorage does not.

What checkstorage won’t catch are issues with index tree (keys out of order, index entries that point to missing rows, rows
that are not indexed).  So checkstorage is not a good substitute for checkdb.

Performance Issue

June 24th, 2012 No comments

Few days back I have faced performance issue in one of our prod data server. I would like to share here.

User was running batch for pushing 90000 rows in a database and batch was not moved from last 1.5 hrs.

On login in the server I found response of the server was not good, it was taking more time to execute a simple query as usual. In first glance, it was looking like user job is hogging the resources, as user job spid was in syslogshold and not moved from long time.

We do some analysis and finally found the cpu usage for server was 100%. ( I used sp_monitor). I concluded that this high cpu usage is slowing down the server performance.

The next task was finding the query which was taking more cpu time. As server was on 15 version, I ran the below sql querry for mon tables for getting the high cpu usage.

select top 10  s.SPID, s.CpuTime, t.LineNumber, t.SQLText from master..monProcessStatement s, master..monProcessSQLText t where s.SPID = t.SPID order by s.CpuTime DESC

http://sybaseblog.com/sybasewiki/index.php?title=Query_-_Which_currently_executing_queries_are_consuming_the_most_CPU_%3F

We asked application team to check the reported spid and if possible, please abort the tran. There was select queries which were  taking maximum cpu . As they requested us to kill, we aborted/killed from data server.

After few seconds, data server cpu started fluctuating from 50 to 100% and finally it was below 50%.

Application batch of 10K inserts moved very quickly and finally issue resolved.

Thanks.

Sybase ASE Database: Cost Considerations and Advantages

June 22nd, 2012 No comments

Recently SAP contracted with IDC to conduct a study of relational database management (RDBMS) users to determine the cost factors encountered by those users in running a relational database, and the extent to which (if any) Sybase ASE could save users money in running their systems. IDC recruited 12 organizations that were willing to let us examine deeply their costs in running both Sybase ASE and other RDBMS products.

IDC asked a number of detailed questions regarding the organizations’ use of database software, their staffing costs, their hardware costs, and their software license and maintenance costs. IDC then analyzed the data using a well-established five-year model for calculating total cost of ownership (TCO), and came to some compelling conclusions.
