Official support and engineering policy for running IQ in virtual machines

$
0
0

What exactly is the official policy for both support and engineering for running IQ in a virtual machine?  If it is supported, which virtual machine systems are supported (also versions if possible)? 

 

  • (RedHat/SuSE) Linux KVM
  • (RedHat/SuSE) Linux containers
  • VMware ESX
  • Microsoft Hyper-V
  • Oracle VirtualBox
  • et cetera

 

Which "Cloud" environments are supported?   Amazon?  Microsoft Azure?  et cetera

 

What, if any, restrictions are imposed on such environments from a Sybase policy perspective?


IQ 16: What is IMB AIX?

What SAN make/model are using for your IQ installation/What's the average write response per i/o?

Hello,

 

If anyone is willing to share, I'm looking for information on what SAN make/model and disk type you're using for your IQ installation and the average write response per i/o from your physical storage you're receiving.

 

Thanks in advance!

Now, I have a sybase IQ 12.7 database running on IBM AIX 5.3, I want to know how to monitor Sybase IQ performance summary.

For example, how many SQL statement  running in 24 hours?  How much time elapsed for every SQL statement ,etc.

IQ DB Auditing

Hi All,

 

 

 

 

I did some readings  on IQ auditing  , I followed below steps :

 

 

 

1.SET OPTION PUBLIC.AUDITING = 'ON'
2.sa_enable_auditing_type('DDL')
3.dbtran -g mydb.log mydb.sql

 

 

I am able to view the  Audit details in mydb.sql  But all the time I need to run the step 3 ,  is this  a  right approach for Sybase IQ auding , Or is there any log file  when I can get details   like we have for HANA .

 

Thanks,

Razal

Where is Sybase Central for IQ?

$

0

In the past it was located in the PC client bundle IIRC.  On subscribenet, I'm only seeing the network client for win32, which doesn't include sybase central. 

 

Please, I'm not talking about Sybase Control Center and am not interested in that until it is rewritten.

How is the -gm parameter effecting query runtime in detail?

$
0
0

During test I found out, that the parameter -gm seems to have some dramatic impact onto runtime of queries. In Detail I found a something like factor 0.5 to 0.6 inside my tests for a smaller system:

-iqtc 12000

-iqmc 12000

-iqlm 1000

-gm 100

-m

-iqrlvmem 6000

 

When setting -gm 1001, runtimes for a single query goes up from about 10 to about 40s.

 

So how is the -gm parameter effecting IQ in detail?


Sybase IQ Monitoring

Hi Team,

 

 

I an doing a Sybase Monitoring setup now  in our new Landscape  , I am bit confused with Results from Stored Procedure ,

 

For Example I used below Query for Memory :

sp_iqsysmon '00:00:1', 'memory' ;

 

'STATS-NAME               ','VALUE                    ','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemAllocated             ','31697086712      (30954186 KB)','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemAllocatedMax          ','32079760856      (31327891 KB)','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemAllocatedEver         ','36008            (     35 KB)','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemNAllocated            ','535547          ','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemNAllocatedEver        ','61              ','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemNTimesLocked          ','0               ','','','','','','','','','','','','','','','','','','','','','','','','','',''

'MemNTimesWaited          ','0       (   0.0 %)','

 

 

What does this value means , Is there a place i can get current Memory and CPU usage of the System .
Is there a system view for this , Or one among the printed status is answer for My question

 

At OS level , I didn't see any matching value for the status here .

 

 

Is there some System views or SP's that can help in monitoring setup .

 

Thanks,

Raza

How Cartesian products affects Sybase IQ performance?

In my IQ message log, I have the following message:

 

I. 04/21 08:28:22. 0001847919 Exception Thrown from dfo_Root.cxx:822, Err# 0, tid 8 origtid 8

I don´t know if

this situation may affect the overall performance

 

Thank you

Backing up Sybase IQ DB

$

I am a backup admin trying to establish a strategy to backup Sybase IQ.

Currently we use Data Domain appliances for most of our backups. My understanding is that the Sybase IQ backup utility does some compression. Wondering if anyone is using DD either as a primary backup target for the DB backups (ie., via a DD NFS mount on the DB server), or as a secondary backup target (ie., backup to local disk, and have backup app sweep the filesystem and backup to DD).? And if so, are you seeing any reasonable dedupe on the Data Domain appliance?

 

Thank you.

Slow HG index creation

$

I am a very new user of IQ 16 (eval version), so please pardon what may be a dumb question.
   
I have a table of 60 billion rows with 26 columns containing non-exotic data (ints and varchars). When I try to create a HG index on one of the varchar columns, the process runs very slowly (won't know how slowly until it finishes but hours certainly), consumes massive amounts of CPU and memory. Is this expected or do experienced users suspect I may be doing something horribly wrong.
   
Thanks for any advice.

Why are some system procedures hidden and others not?

$

I'm rather perplexed as to why certain IQ system stored procedures are hidden (pseudo-encrypted) and others not.  Is this simply a matter of IQ engineers submitting code to hide the stored procedure on personal preferences or is there a valid reason to hide the system procedures? 

 

With how buggy IQ is, largely due to the fact that the user base of IQ is rather small, I would expect that all the stored procedures with possibly the exception of sp_iqpassword be unhidden.

 

For example, the sql for sp_iqstatus is visible (v16.0 sp3):

 

ALTER PROCEDURE "dbo"."sp_iqstatus"()

result(

  "Name" varchar(255),

  "Value" varchar(128) )

sql security definer

begin

  declare local temporary table "iq_status_temp"(

    "Name" varchar(255) null,

    "Value" varchar(128) null,

    ) in "SYSTEM" on commit preserve rows;

  execute immediate with quotes on

    'iq utilities main into iq_status_temp status';

  select "Name","Value" from "iq_status_temp";

  drop table "iq_status_temp"

end

 

where as sp_iqtable is not:

SAP IQ 16 remote procedure to MsSQL 2005 error.

$
0
0

Hi all,

    I've in IQ a remote procedure that call via RPC an old MsSQL 2005 stored procedure.

 

In my old installation with IQ 12.7 ESD 4 all works well and I don't report any issues.

Actually with the new IQ 16.0 SP08 I've the following strange behaviours.

 

ERROR 1) When I call the remote procedure from IQ using SAP Interactive SQL all works well if I run the client from a remote host. I mean from an host which is not the server where IQ engine is running. If I execute the same call (always from SAP Interactive SQL) on the IQ engine server the following error is reported:

 

There was an error reading the results of the SQL statement.

The displayed results may be incorrect or incomplete.

 

Cursor not in a valid state

SQLCODE=-853, ODBC 3 State="24000"

Cursor not in a valid state

SQLCODE=-853, ODBC 3 State="24000"

 

Server 'SVR_PRODOTTI': [Microsoft][ODBC SQL Server Driver]Function

sequence error

SQLCODE=-660, ODBC 3 State="HY000"

 

ERROR 2) I've the following scenario:

 

     a.     I call a remote procedure (always the MsSQL 2005 remote procedure described above) inside a standard IQ stored procedure

     b.     the remote procedure fill a remote table with some data

     c.     in IQ after that the remote procedure is executed I want to get the produced data in IQ via proxy table

 

Looking at MsSQL side I note that step (a) and (b) are executed, but when step (c) start running it remains blocked by the session that had run step (a and b) even if they are already finished. Look at the following extraction of session state by MsSQL side.

Environment details:

IQ -> SAP IQ 16.0 SP08 on Win 2012 R2 server (64 bit)

MSSQL -> MsSQL 2005 SP 2 32 bit Enterprise on Win 2003 server (32 bit)

 

Do you have any suggestions about this strange behaviours?

 

Best regards,

Stefano

Does IQ support huge pages on Linux x86-64?

I ask because I don't see any references to huge memory pages in the IQ manuals or white papers.  I know ASE supports it.  If not, why not?

In big IQ installation you also will pay for partitioning ,  each node in MultiPlex, and ability to use BLOB and CLOB fields.

Are you ready to pay for this?

 

SAP HANA licensed  by  data volumes. Partitioning, nodes, BLOBs, CLOBs - all include in licenses.

 

What do you think about?

 

 

 

 

Product Editions

SAP Sybase IQ is available in several product editions.

EditionDescription

Enterprise Edition

Supports all options and features.

Optional features require additional licenses that are purchased separately.

Small Business Edition

Supports most of the functionality available in the Enterprise Edition, but does not support multiplex or any optional features.

Single Application Server

Provides the same functionality as the Small Business Edition, but is restricted to use in a one- or two-machine environment.

Evaluation Edition

Supports all options and features available in the Enterprise Edition for a 30-day evaluation period.

Express Edition

Supports all options and features available in the Evaluation Edition.

Unlike the Evaluation Edition, the Express Edition does not expire, but does restrict the size of all IQ main dbspaces, permit other incremental license options, and cannot be deployed in a production environment.

Hi all,

       on 17/01/2014 I installed SAP IQ 16 in Express Edition mode. 

I understood that Express Edition is not time limited (like 30 days trial edition), but it is limited in datatstore size (5 GB for datatstore).

Now, 30 days later, the following error is reported in log files during startup.

 

..

  1. I. 02/17 11:18:54. Transaction log: iqdemo.log
  2. I. 02/17 11:18:54. Starting checkpoint of "iqdemo" (iqdemo.db) at Mon Feb 17 2014 11:18
  3. I. 02/17 11:18:54. Finished checkpoint of "iqdemo" (iqdemo.db) at Mon Feb 17 2014 11:18
  4. E. 02/17 11:18:54. Error: No SYSAM License Available

 

  1. E. 02/17 11:18:54. No SYSAM License Available
  2. I. 02/17 11:18:54. Database server shutdown due to startup error

...

 

 

Just to give you a complete problem vision, hereafter I report the screenshots used to install the SAP IQ Express Edition.

Are there something wrong in the installation process described above?

Do I need to request a specific "Express license" to use IQ Express Edition? How can I do that?

 

 

Thank you and best regards,

Stefano
