SAP Sybase IQ Operations Known Issues from Previous Versions

Descriptions of known issues and workarounds for SAP Sybase IQ operations from previous versions.

dbisql Reports Java Stack Trace Error [CR #624363]

On rare occasions, the Interactive SQL utility (dbisql) may encounter a Java stack trace error when you highlight text:
Index Array Out of Bounds

This is due to a problem in the Java Runtime Environment. See Bug ID 6921603 in the Java Bug Database on the Oracle Sun Developer Network (SDN).

sp_iqstatus Returns Error on Chinese and Japanese Locale Installations [CR #622928]

On SAP Sybase IQ servers that are set up for Chinese and Japanese locales, running sp_iqstatus returns an error similar to:
Could not execute statement.
Syntax error near '2010' on line 1
SQLCODE=-131, ODBC 3 State="42000"
Line 1, column 1
Workaround:
  1. Stop the server.

  2. For Chinese locales, remove dblgzh_iq11.dll from %IQDIR16%\bin64.

    For Japanese locales, remove dblgja_iq11.dll from %IQDIR16%\bin64.

  3. Restart the server.

After this procedure, certain strings in the .iqmsg files and the output of sp_iqmpxinfo, sp_iqstatistics, and sp_iqstatus are in English, instead of Chinese or Japanese.

ASE Connections to SAP Sybase IQ with BIGDATETIME [CR #622007]

When a version 15.5 GA Adaptive Server Enterprise server uses Component Integration Services (CIS) to connect to an SAP Sybase IQ server version that has BIGDATETIME and BIGTIME capability, any chronological data type sent to the Adaptive Server server using CIS results in the error:
Msg 7225, Level 16, State 4:
Line 1:
Unknown datatype token 188 'BIGDATETIME NULL'
encountered.
Exited passthru mode from server 'QA_IQ16_ASECIS'.

SAP Sybase IQ sends the data as BIGDATETIME and relies on Adaptive Server to convert appropriately. The BIGDATETIME data type was implemented in CIS in Adaptive Server Enterprise version 15.5 ESD #1, so this error occurs with Adaptive Server Enterprise 15.5 before any ESDs have been applied.

Workaround:

SET TEMPORARY OPTION RETURN_DATE_TIME_AS_STRING='ON' in SAP Sybase IQ for each session. The SAP Sybase IQ server sends all chronological data as strings and Adaptive Server completes the conversion. This workaround is for Adaptive Server Enterprise 15.5 GA connecting to SAP Sybase IQ in passthrough mode.

You can also use this workaround in the definition of a remote stored procedure, but it is not a solution for proxy tables created on Adaptive Server returning chronological data types from SAP Sybase IQ.

RSA Certificate Creation Fails [CR #557702]

RSA certificate creation fails with the error createcert command not found because the createcert utility is missing. The utility is currently available only on the AIX64, LinuxAMD64, Sun64, Win32, and Win64 platforms. Please contact Technical Support if you need this utility.

FORWARD TO from SAP Sybase IQ to ASE Fails [CR #539484]

Execution of a FORWARD TO command from SAP Sybase IQ to Adaptive Server Enterprise using the ASEODBC driver fails with ASA Error -660 “The identifier that starts with ‘<identifier>’ is too long. Maximum length is 28.”

Workaround:

To avoid this problem, do one of the following after creating a remote Adaptive Server Enterprise server using either server class aseodbc or server class asejdbc and before executing a SQL statement that contains a string with double quotes against the remote server using the FORWARD TO statement:
  1. Change the double quotes to single quotes.

  2. Include the database option SET QUOTED_IDENTIFIER OFF before the SQL statement to be executed:
    FORWARD TO <remote server name> {
    SET QUOTED_IDENTIFIER OFF
    <SQL statement>
    } 
  3. Set the QUOTED_IDENTIFIER database option to OFF using a separate FORWARD TO statement:
    FORWARD TO <remote server name> { 
    SET QUOTED_IDENTIFIER OFF }

Creating Very Large Databases

Attempting to create extremely large SAP Sybase IQ databases on certain Windows configurations may fail with an exception occurring in the module hos_bion.cxx at or near line 182.

If you require a database that exceeds 100GB, try creating a database of that size to see if your system configuration exhibits the problem. If you create a smaller database and later try to add dbspaces, correcting the problem at that time may be more difficult and time consuming.

This problem is intermittent but tends to occur if you have approximately 180GB of open files. Changing the setting of the OS_File_Cache_Buffering database option could trigger the problem. In some cases, you might see an INSUFFICIENT_RESOURCES Windows error message.

The best way to avoid this problem is to create on a raw device any databases that may become larger than 180GB.

If you create a very large database on a file system, and either the CREATE DATABASE statement fails as described above, or you see the INSUFFICIENT_RESOURCES message, apply Microsoft corrections. The problem is caused by a bug in the Windows kernel. More information is available on the Microsoft support Web site:
