How to do Application Tracing in ASE

January 20, 2016, 4:50 pm
$

If ASE server was been disable MDA monitoring, you hit a query issue frequently and hard to identify the exact query being run by the user at the point in time. You want to capture submitted SQL using application tracing.  

Following is steps of Application Tracing:

  1. Use sp_who to find the spid of the slow query in application.
  2. set tracefile 'pathname' for spid
  3. Enable desired options
    dbcc traceon(3604)
    set show_sqltext on
    set statistics time, io on
    ...
  4. Check tracing (sp_helpapptrace)
  5. (run test in application)
  6. set tracefile off for spid

       For example, during the slow query being run:

      -------------------------

      isql -Usa -P<pwd> -S<servername>

      1> sp_who                                   --find spid of the slow uery, e.g. spid 12

      2> go

      1> set tracefile '/tmp/spid12_20150825.out' for 12

      2> go

      1> dbcc traceon(3604)

      2> go

      1> set show_sqltext on                 --'set' commands apply to session 12 from now on

      2> go

      1> set statistics time, io on

      2> go

          <Waiting for the query (session:12) to finish>

      1> set tracefile off                      -- disable tracing

      2> go

      1> set tracefile off for 12

      2> go

      You could find trace output in tracefile: '/tmp/spid12_20150825.out'.
      -------------------------

Application Tracing in ASE 15.0.2 and above:

  • Capture executing SQL in another session
  • Capture diagnostics output from that another session into a file
  • Set options in another session than yourself 
          set showplan, set statistics...
  • All fully transparent to the session being traced

Please note:

  • set tracefile {'pathname' | off } [for spid]
    1. Saves all SQL text to a flat file until turned off
    2. Session tracing is enabled for the spid/session being traced.
        It is not the perspective that the sa session is tracing a spid, but rather that a spid is being traced
    3. You can also trace yourself -- for example from a login trigger
       
    Restrictions
    1. You cannot save the SQL text for system tasks (housekeeper, checkpoint process, etc.).
    2. You must have the sa or sso roles, or be granted set tracing permission
    3. set tracefile is not allowed to open an existing file as a tracefile.
    4. During an SA or SSO session, if you enable set tracfile for a specific spid, all subsequent tracing commands executed take effect on that spid, not the SA or SSO spid.
    5. You cannot trace more than one session at a time from a single sa or sso session.
    6. You cannot trace the same session from multiple sa or sso sessions.

           Notes
           1. The file storing the trace output is closed when the session being traced quits or when you disable tracing.
           2. Before you allocate resources for tracing, keep in mind that each tracing requires one file descriptor per engine.

  • sp_helpapptrace
    System proc reporting sessions being traced, and those doing the tracing.
      
  • Set options that affect tracing
    set show_sqltext [on | off]   (requires trace flag 3604 to be on)
    set showplan [on | off]
    set statistics io [on | off]
    set statistics time [on | off]
    set statistics plancost [on | off]
    set option show [normal | brief | long | on | off]
    set option show_ …. (etc)  
      

  • Tracing a session

    Once you have enabled tracing for a session, any further set commands associated with QP debugging take effect for the session being traced vs. the session issuing the commands.

Sybase log

Dear Team,

 

We are new to Sybase database, while installing SAP ECC system we have created 2 logs as saplog_1 and saplog_2 each of 40gb

in dbacockpit we can find database details options set as Truncate log on checkpoint = Yes

 

But when we check transaction log usage the log used is mostly 0 MB attached file for reference

 

But system is a development and continuously used by development/Functional team and logs are not generated

 

Usually comparing to oracle archive logs fills up timely many a time but not seeing such actions in sybase

is there a configuration issue or Sybase works like this kindly advice

 

Thanks and Regards,

Praveen

Hi experts,

 

I have installed a distributed configuration of BO BI 4.1 SP5 on Linux RH 6.5 with Sybase ASE 15.7 SP 131 :

 

SAP ASE 15.7 SP131 on one server & CMS on an other server.

 

Everything works well.


Now, I would like to activate "net password encryption reqd" on my Sybase server.

 

But when this parameter is activated, CMS server doesn't start anymore :

Can I ignore this messages? ... it is a box with NetWeaver 7.02 (BW usage) on ASE 15.7.136 on Windows but I see same situazion on a ECC 6.05 on ASE 15.7.131

 

Number of network task should be one on Windows... and optmization goal shoould be allrows_mix... is it true?

ASE 16K Page Size

January 29, 2016, 11:48 am

Hi

 

Building a new ASE 15.7 server to migrate from 2K to 16K page size. Few questions, would like advise on.

 

1) The configuration required removing all buffer pools lower than 16K as it was throwing error on log otherwise. Is this as expected?

2) The create database command appears to create the log size differently to that specified. For instance 'create database test on dev01='60M' log on devlog01=15' creates the database as 72Mb (60Mb data, 12Mb log). Is this as expected.

3) How should cache pools be defined in caches for 16K?

4) Are there known real case issues with use of 16K page migrations?

 

Thanks

Jay

IDES EHP7 Installation error SAP SYBSQL_SID service can not be started code 1067 & 1053

Hi,

 

 

I am trying to install SAP IDES EHP7 system using Windows 2012 & ASE Sybase 16.

 

Currently I am stuck at installation phase "Configure Database Components" where SAP has attempted to restart Sybase DB service but it has failed and until DB service will be up installation can not be progress further.

 

Following are my observations w.r.t SAP SYBSQL_ID1 service

 

Installation is trying to restart Sybase DB service

service is stopped & not getting started

trying to start it manually

service failed with error 1067 : The process terminated unexpectedly (When service has local user credentials i.e. ".\sybid1" )

In the Windows Event log, I am getting below messages

After that I used one domain A/c to start the service i.e. "domainXYZ\sybid1"

then I am getting error 1053: Service did not respond to the start or control request in a timely. fashion.

 

In the event log I am getting time out error, I tried to increase time out value to 24 hrs.(https://support.microsoft.com/en-us/kb/884495) but its still failing & running for only 30-40 seconds, however event log shows new value of time out i.e. 86400000 so changes are reflected but service is not getting started.

 

 

As this is Windows service issue, I am not getting any logs anywhere else (not in sapinst_instdir as well).

 

Kindly suggest is there anyway to forcefully start Sybase database or Is it possible to recreate service as stated in link Error 1053: The service did not respond plz

 

If I am going for recreation of service manually then will there be any impact on installation which is halted now w.r.t. any registry changes.

 

Thanks for your response.

 

Best Regards,

Kiraang.

SAP Distributed Installation (Database server with several DB instances with Sybase ASE DB)

Hello,

 

I´m with some doubts regarding the installation of Sybase ASE database in a SAP distributed installation. I have to servers, one server for the SAP application instances (ASCS/SCS and PAS instances) and other server for all databases instances (two database instances). This database host should have two database instances, for two SAP systems, to the future Solution Manager (SolMan) and Process Integration (PI) systems.

 

In past I already installed a SAP system on a Sybase ASE database, but it was in a standard installation, this is, all the instances (SAP instances and database instance) were installed in the same server. But now, in a distributed installation, which I want to install two database instances on a Sybase ASE database, what I have to do?... I mean... howshould I installthe Sybase ASE database? In a standard installation the installation of Sybase ASE database is performing during the SAP installation (using the SWPM). In this specific case, using the distributed installation option, the binaries of Sybase ASE DB are installedfirst/before or this is part of the SAP installation...!?


Can you clarify me please?... because in SAP installation guide, in section "Distributed System Installation" I don´t see anything about this...!



Thank you,
