Hi all,

We are monitoring an Sybase IQ 15.4 Server (simplex configuration) with performance Monitor of Sybase Central

When we see on section of CPU Usage, we can see "CPU user usage" with values over 600%, what does it mean?

Thank you for your support

Time is a key dimension of data, and integral to its meaning and importance.  Any data that changes has a temporal quality – taking on different values at  different times.  It is often necessary to be able to look at a snapshot of what the world looked like at some point in the past, and take action based on that state.  Consider these kinds of scenarios:

• An internal audit requires a company to report on changes made to financial data during the past five years.
• A pending lawsuit prompts a hospital to review a patient's medical data just before a new treatment was ordered.
• A client challenges an insurance agency's resolution of a claim involving a car accident. The agency needs to determine the policy's terms in effect when the accident occurred.
• A retailer needs to ensure that no more than one discount is offered for a given product during any period of time.
• A customer inquiry reveals a data entry error involving a three-month introductory interest rate on a credit card. The bank needs to retroactively correct the error.

These are critical questions, and require the ability to reach back in time and query data as it existed in the past.   How do you easily maintain snapshots of data in SAP IQ, so that you can answer questions based on date and time?  SAP’s own Mark Mumy from our Global Center of Excellence, recently shared the following approach that he has used in real world implementations.

Suppose you want to find out the state of data at a particular point in time.  For database tables that store changing data, do the following:

Imagine that you have this data for table “insurance_policy”:

So let’s say you are investigating a policy claim made in 2005, and want to know what the associated insurance policy terms were at that time.  You would issue the following query:

SELECT policy_details

FROM insurance_policy

WHERE policy_id = ‘11111’ and ‘2005-01-01’ between effective_date and end_date

This would pull the fourth row of data, because 2005-01-01 is between the effective_date and end date of this row.  This gives you the details of the insurance policy as of January 1, 2005.

So that’s it – a simple and low overhead way to represent and query temporal data in SAP IQ.

Hello All,

I am a student and just want to try my hands on SAP IQ. So i downloaded SAP for linux. I set up a Virtual machine on my windows and loaded the linux image onto the virtual machine. So far i have been successfully able to install SAP IQ, create database and so on. But I have only got as far as authenticating the agent after registering it. When i authenticate the agent it gives me the below error and obviously the authentication fails

"com.sybase.scc.jmx.ManagedObjectGateway.err_invoke_op SCC agent db2v105:9999 does not know Sybase IQ version string. Something is wrong with the IQ Agent plug-in."

So i searched on internet and followed the process mentioned in SAP info center under change request number 723112 however I am still unable to get it working. I would be really grateful if someone could help me ASAP. Thanks in advance

Hi Team,

Could you please explain me the difference between Multiplex server and single server.

I also read that we can register only one database to IQ server.

Initially, post installation I have created a demo database and registered it to IQ server. So does this mean that I will not be able to to create a new database in SCC and subsequent database objects under it.

Thanks & Regards,

Vijay

HI,

Please Can anyone tell me the steps to take virtual backup in Sybase IQ 15.4

Thanks in Advance.

1. Problem

[Environment]

    - SAP IQ16 (MPX)

A User failed to drop multiplex server due to below error.

DBA) drop multiplex server Writer1;

[Error]

SQL Anywhere Error -198: Primary key for row in table 'ISYSIQMPXSERVER'

  is referenced by foreign key 'ISYSIQMPXSERVER' in table 'ISYSIQMPXSERVERAGENT'

2. Cause

ISYSIQMPXSERVERAGENT table stores agent connection definitions for the specified multiplex server.

  Constraints :

  - Primary key(server_id)

  - Foreign key(server_id) references SYS.SYSIQMPXSERVER

Primary key(server_id) for row in table 'ISYSIQMPXSERVER' is referenced by foreign key 'ISYSIQMPXSERVER' in table 'ISYSIQMPXSERVERAGENT'.

3. Solution

If agent exists, Need to drop the agent before drop the multiplex server.

DBA) select * from SYSIQMPXSERVERAGENT.

  DROP AGENT Statement

  : Deletes an SAP Sybase IQ agent for SAP Control Center.

[syntax]

  DROP AGENT FOR MULTIPLEX SERVER server-name;

  Ex) Drop agent for multiplex server Writer1;

Thanks

I recently activated the Cockpit Server and Agent (4 SP08 PL1) to monitor a single SAP IQ server 16.0 SP8 LP3.  I also set the alert to send me email using the default alert threshold.

After a few hours I started receiving alert from cockpit indicating that the main cache in use exceeded the thresholds.  As the main cache was getting filled up, the alerts were changing from LOW to HIGH priority. At the end, I was flooded with alerts for the main cache and disabled the monitor for the main cache.

As per SAP IQ documentation:

“Number of buffers in use. Normally this is 100% because the buffer manager leaves buffers in memory until they are needed for some other data. In general, the buffers used and buffers locked numbers are meaningless, because SAP IQ uses buffers as aggressively and efficiently as it can.

This value grows to the maximum number of buffers that fit in the main buffer cache. The number increments whenever a buffer is allocated, but decrements only when a buffer is destroyed, not when it is unlocked or flushed. Objects in the temporary cache release their buffers when they are finished, but in the main buffer cache, SAP IQ may or may not destroy the buffers because as long as a buffer is unlocked, it is available for reuse, whether it is empty, contains data, or contains destroyed data.”  SAP IQ SP08, Administration: Database; Table 27: IQ Main Store Blocks Message; Page 320

It seem to me that having a Main Cache 100% should not raise an alert, but the alert should be raise if the number of disk I/O is high indicating that there is excessive trashing for the main cache.

1. Do I’m missing something?
2. What is the use of having and alert to monitor the main cache used?
3. Is there a method to flush the main cache while the database is online?

Thanks a lot,

Uvernes.

Hi all

Does IQ as start-up check the assigned or used space to determine if the current vldb licenses are valid?

Hi all,

We’re facing issue with SAP IQ on AIX. Interestingly, we’re unable to execute procedure. Sample of error screen is shown below. although we can create database, can start database.

Any advice on the above?

Many thanks

Toute l'actualité SAP ASE 16 et SAP IQ lors des #SAPExperienceDays, le 15 octobre matin. Agenda sur http://bit.ly/1s4BYCO

We would like to create proxy table in IQ 15.4 latest patches applied, real table being in ASE, we use aseodbc connection. At the creation of  the proxy table we are faced with the following error:

Could not execute statement.

  SQL Anywhere Error -656: Unable to connect to server 'ASE_SERVER_NAME':

  [Sybase][ODBC Driver Manager] Data source not found and no default

  driver specified

  Sybase error code=11206, SQLState="WO001"

  Line 1, column 1

  create existing table TOTO at 'ASE_SERVER_NAME.myDB.dbo.TOTO_ON_ASE'

we have tried to put the columns description in teh create statement it doe snot chnage anything at all.

Unfortunately our dbas do not know much about IQ. One of them has opened a case with SAP.sybase; no reaction from them as yet after 10 days

Please help us advance with our work.

All you help and suggestions are gratefully appreciated.

Hi,

We are facing this issue.

If we copy 10GB of data from Table A to Table B, Table B supposed to have 10GB size however it is allocating almost 1.6 times of parent table(so Table B is having 18GB).

We tried below solution :

Before table creation & load, we set the parameter ‘set option public.minimize_storage = ON.

Direct load instead table creation and then load ‘select * into Table B from Table A’.

Rebuild the system index on individual table (sp_iqrebuildindex ‘gateway.Table B’, ‘index index_name’)

Can anyone help us.

Regards,

Santosh Negalur

sp_iqsysmon system stored procedure monitors multiple components of SAP IQ, including the management of Buffer allocations, Buffer manager, Buffer pool, Catalog statistics, CPU utilization , Free list management, Memory management,  Prefetch management, IQ RLV-Memory Store statistics , Large Memory Allocator(LMA) statistics,  Server context statistics, Thread management and Transaction management.

Large Memory Allocator has been added in SAP IQ 16 and is responsible for enforcing large memory allocation.  Large memory is used by load and query engine.

Example:  Starts sp_iqmonitor in the file mode and write statistics for Large Memory Allocator(LMA) to the log file

sp_iqsysmon start_monitor,'filemode' , '-section lma'

sp_iqsysmon stop_monitor

Large Memory Allocator (Statistics)

Large Memory Space 8421m

Large Memory Max Flexible  2105mb

Large Memory Num Flex Allocations  0

Large Memory Flexible %     50%

Large Memory Flexible used 0 mb

Large Memory Inflexible %  90%

Large Memory Inflexible used  0 MB

Large Memory Anti-Starvation %  50%

Large Memory Num Connections 0

Large Memory Space” – Maximum Large Memory configured size (-iqlm value from params.cfg)

“Large Memory Max Flexible” -  Maximum memory granted for flexible  operators. (e.g Load Engine(hash sort merge for hash/has-range partitioned table and hash sort merge cursor)).

“Large Memory Num Flex Allocations” – This is the count of memory chunks allocated as flex memory.

“Large Memory Flexible %” – percentage of large memory used for flexible operators.

“Large Memory Flexible used” –   This is the total amount of memory allocated to flex users.

“Large Memory Inflexible %” –  Percentage of large memory used for inflexible operators(N-bit metadata structures, data buffer of column vector in load ).

“Large Memory Inflexible used” – Large memory used  by inflexible operators

“Large Memory Anti-Starvation %” – This only applies to flexible operators.

“Large Memory Num Connections” – This only applies to flexible operators and is the number of clients using lma.  Internal concept only – has nothing to do with DB connections or users.  There could be unregistered users too so this is not an accurate count of users.

After several days IQ Cockpit froze, it was stopped normally and now it fails to start with the messages below. Also in the same installation SCC is not running, it only starts the agent, not the web app. Any ideas?

During upgrading to IQ 16 we fould that the load commands containing the "block size" and "block factor" clauses fail. This is documented int hdiscontinued features of IQ 16 (SyBooks Online)

However the customer uses Informatica as ETL platform which adds these cluases by default in the load command. Is there any way to allow this syntax in IQ 16, or we should rewrite all the files containig the load commands? Any other suggestion?

A user sometimes needs to change port number in mpx environment.

Environment

SAP IQ15.x, IQ16.x all (MPX)

If user wants to change the port number of coordinator, Here are steps to change the port number.

1. ALTER MULTIPLEX SERVER iq154MPX_C HOST '10.34.193.108' PORT 2649; --> new port number (2649)

2. Coordinator is shutdowned because of configuration change.

              I. 10/07 16:34:26. 0000000188 Warning : Multiplex server changed configuration: 'Connection Info' which needs Shutdown.

              I. 10/07 16:34:26. 0000000188 Warning : Multiplex server iq154MPX_C is shutting down because of configuration change.

3. change the port number from old to new port number in cfg file.

4. restart coordinator

5. check the consistency using sp_iqmpxvalidate

[Cautions]

         ** I recommend to shutdown all secondary nodes because DDL/DML is not working before change the port number.

[Files to be changed]

1. odbc file
2. cfg file
3. interfaces file
...

Hello ,

Could you please let me know  Is there a way to export performance data from IQ in text file ?

We would like to  perform trend analysis of the performance data.

I guess   sp_iqsysmon can be used in file mode to monitor perforrmance.

Is there any good script in limux to perform this monitoring.

What are the thresholds in sp_iqsysmon report that needs to  be  monitored.

Regards,

AK
