ASE 15 Performance and Tuning Guides
Does anyone know when the updated ASE 15 versions of
"Performance and Tuning Guides" will be released?
The guides on sybooks are for ASE12.5.1
Thanks in advance.

I *think* that they were supposed to be released sometime
later this year, but I don't have any clear information.
I'm not aware of when these will be released. I'm guessing some time after the
Ho...Check List for ASE 11.9.2 Performance Tuning
We need to troubleshoot the performance issue in an ASE 11.9.2 server.
During the system in a slow response time state, about 20 Sh_page locks (Non
Cursor Lock) found on the syslogins when I execute the sp_lock.
Can anyone give me some advise on which areas I should check first (may be a
check list) ?

I'm using ASE 11.9. Does anyone know which is the most efficient whay to
speed up the ASE server ? I have a stored procedure carries out following
things using a CURSOR:
- Read record from table_a
- Do some data manipulation to the record read
- Insert record to table_b if record is not exist in table_b
- Update record to table_b if record is exist in table_b
table_a contains around 40,000 records and table_b contains around 300,000
Originally, my coding in the stored procedure is as follow:
SELECT .... FROM table_b WHERE ...
IF @@rowcount > 0

I have a pb application running on sybase db.
It is very slow.
We used PFC for developing the application.
I would like to know what is the best to way to tune the performance of the
Any ideas are greatly appreciated .
Thanks in advance..
From my experience, performance problem mostly due to inefficient SQL
statement. Check which SQL statement caused the problem and then tune that
Hope this can help.

Could it be possible to take scripts from ASA and load them in an ASE
Any information is welcome
ASA supports a fairly large sub-set of Transact-SQL, so if you write your
stored procedures and triggers in ASA using T-SQL, you should be able to
create scripts that will run against both ASE and ASA. If you're planning
to do this though, I would suggest developing your database schema against
ASA, since everything you write in T-SQL in ASA will be supported on ASE,
but the reverse is not true.
Check out the section in the ASA documentation entitled "Tra...Performance tuning

This sounds like some JDBC Call might be happening in your application -
offheand I don't
know exactly what, but something like Connection.getCatalog()
I don't think jConnect caches this sort of thing - so it might be the
application code makes the call for each command execution.

I setup 2 ASE servers (same hw) in other sites, but one of ASE is runnig so
slow. Users take more than 5 minutes to load a report while other users take
less than 5 seconds to load same report on another "fast" ASE. Why? Attached
my sysmon report, pls comments on this server and advise solutions. Thanks.

Is anyone out there doing ASE to ASE replication using SQL remote? If
you are have created your own version of the SSEXTRACT utility to set up
a replicant database in ASE rather than ASA? Or does anyone know if
SYBASE has created a version SSEXTRACT for use with ASE to ASE
Thanks in advance
I thought the SQL Remote Replication support in ASE11.5 was meant for a
consolidate-database only (by design)! At least that was what Sybase
said when they announced support for SQL Remote technology support in

Is there a way to create and analyze some kind of trace files with SQL
I have a program that issues "generated" SQL statements. I'd like to
quickly look for those that create full table scans in any of the used
tables to see if I can optimize data access.

I wrote something like this a couple months back. It interrogates the
trace file that PowerBuilder produces. It's rather proprietary since
it's one of the tools that I use when I do Performance & Tuning
Hi there, ask a rather beginner question here.
we have this ASE12.0 on Solaris 7. it's a enterprise 3000
machine, with 1G RAM, 2 CPUs both 168MHz. via /etc/system
assigned 800M to ASE. All other settings in the configure
file are mostly DEFAULT.
we donot have many concurrent users on system most of the
time, and the workload/ transaction is not very high. (most
time, just 50 to 60 users online).
however, lately users complains performance problem. esp
just only one user was running a little big large report.
and when I check sp_lock, actually very few locks, and just

We intalled a Sybase IQ 12.5 on a HP-UX, we have a IQ
database of 255 GB, some of the querys are very slow,
please, what are the main aspects that we have to look for
to get a better performance ??.
main things (imho):
indexes, optimization of memory usage, iqtc 60% of memory.
The rest need to see more info about your tables, indexes, query plan, type
of querys, HW etc

I run select * statement from a view on both ASE11.5 and ASE12. The speeds
for returning the value are very different. On ASE11.5, it only takes 1min
while on ASE12, it takes 30min.
ASE12 has bigger data caches for the database and tempdb than what the
ASE11.5 has. Both of them have the same indexes. After I run sp_sysmon on
ASE12, in the report of data cache management, ASE12 has high cache hit
ratio (that is good) and high pool turnover (no good). Does that mean I
need to increase the data cache for ASE12? I also noticed that in OS, ASE12
has very tight free mem...ASE performance
I'm new to Sybase, so excuse me if this is a stupid
question, and I guess I might not supply enough information
to make an informed judgement ...
We've got ASE 12.0 running on a Sun Sparc server with 2 x
450Mhz processsors and 2 gig RAM + RAID. We run a script
which updates a join table - i.e. a table with two integer
columns with keys in them. The sql script inserts a total of
1.8 million rows into the table and the entire operation
takes around 18 minutes to complete.
Does this sound like reasonable performance - it feels slow
to me, but I don't have any comp...
