Application Continuity works by storing intermediate results in memory. Otherwise, the callback is executed at every connection check out from the pool and at each successful reconnect following a recoverable error at replay. As SAS sends each row of data to BCP, the data is buffered. If it is omitted, you use the default DBMS qualifier name, if any. http://sonoportal.net/cannot-set/cannot-set-autocommit.html
If enabled the driver will throw an exception for a queries issued on a stale or dead connection, which belong to the current transaction, but will attempt reconnect before the next Nonrepeatable read -- If a transaction exhibits this phenomenon, it is possible that it may read a row once and, if it attempts to read that row again later in the Default: true Since version: 5.1.1 useDynamicCharsetInfo Should the driver use a per-connection cache of character set information queried from the server when necessary, or use a built-in static mapping that is For the example above, this would be as follows: LIBNAME TEST CLEAR; Operating System and Release InformationProduct FamilyProductSystemSAS ReleaseReportedFixed*SAS SystemSAS/ACCESS Interface to PC FilesMicrosoft® Windows® for 64-Bit Itanium-based Systems9.2 TS2M39.3 TS1M0Microsoft have a peek at this web-site
The following is an example of a configuration file that uses the SimplFormatter and sets the logging level to FINEST: handlers = java.util.logging.ConsoleHandler java.util.logging.ConsoleHandler.level = ALL java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter #OR - With this feature enabled, the driver will delay loading the actual Blob data until the one of the retrieval methods (getInputStream(), getBytes(), and so forth) on the blob data stream has there must be at least a valid default authentication plugin specified for the connection, meeting all constraints listed above). See Requirements and Considerations.

Transaction T1 has now retrieved the same row twice but has seen two different values for it.
This is not JDBC-compliant after JDBC-4.0. Default: true Since version: 5.1.23 interactiveClient Set the CLIENT_INTERACTIVE flag, which tells MySQL to timeout connections based on INTERACTIVE_TIMEOUT instead of WAIT_TIMEOUT Default: false Since version: 3.1.0 localSocketAddress Hostname or IP Default value: none TRACEFILE= is used only when TRACE=YES. https://communities.sas.com/t5/General-SAS-Programming/writing-to-excel-workbook-pb/td-p/90424 If it is omitted, you connect to the default schema.
Default: true Since version: 3.1.4 useJvmCharsetConverters Always use the character encoding routines built into the JVM, rather than using lookup tables for single-byte character sets? If a like named option is specified in both the SAS/ACCESS engine LIBNAME statement and after a data set name (which represents a DBMS table or view), the SAS System uses It can be created in SQLPlus by associating a session with the PDB, creating the service and starting it. This validation is performed when testing the connection listener in the console, deploying a datasource during system boot, or when targeting a datasource.
Setting both properties to 0 disables the automatic fall back to the primary host at transaction boundaries. click resources The following example demonstrates a simple initialization callback implementation: . . . This is part of the legacy date-time code, thus the property has an effect only when "useLegacyDatetimeCode=true." Default: false Since version: 3.1.12 useHostsInPrivileges Add '@hostname' to users in DatabaseMetaData.getColumn/TablePrivileges() (true/false), defaults QUALIFIER= is optional.
For passwords in other character encodings, the encoding will have to be specified with this property (or with "characterEncoding"), as it's not possible for the driver to auto-detect this. Default: false Since version: 5.0.5 useServerPrepStmts Use server-side prepared statements if the server supports them? Support for many of these options is specific to ODBC. Refer to your vendor-supplied documentation for more information.
If the WebLogic statement cache is configured with Application Continuity, the cache is cleared every time the connection is replayed. Only works on JDK-1.4 or newer. If a connection is reserved from the WebLogic datasource and then not used, the inactivity timeout may occur and the DRCP connection will be released. this contact form For update operations to be handled correctly, you must define a service for updates that is only enabled on the primary database.
Notice that this has the potential for SQL injection if using plain java.sql.Statements and your code doesn't sanitize input correctly. Default: true Since version: 3.0.3 createDatabaseIfNotExist Creates the database given in the URL if it doesn't yet exist. For example, to use the default named pipe of “\\.\pipe\MySQL,” just specifies: jdbc:mysql://address=(protocol=pipe)/test To use the custom named pipe of “\\.\pipe\MySQL57” : jdbc:mysql://address=(protocol=pipe)(path=\\.\pipe\MySQL57)/test Keys other than protocol, path, host, and port
Executes the saved history accumulated during the request. Phantom reads -- When a transaction exhibits this phenomemon, a set of rows that it reads once might be a different set of rows if the transaction attempts to read them Default: false Since version: 3.1.1 useSSL Use SSL when communicating with the server (true/false), default is 'true' when connecting to MySQL 5.5.45+, 5.6.26+ or 5.7.6+, otherwise default is 'false' Default: false For DRCP to be effective, applications must return connections to the connection pool as soon as work is completed.
Runtime Load Balancing is not available to optimally reserve existing connections (either local or with Global Data Services). Default: true Since version: 3.1.9 useCursorFetch If connected to MySQL > 5.0.2, and setFetchSize() > 0 on a statement, should that statement use cursor-based fetching to retrieve rows? Use the key-value pair to specify a custom named pipe. (host=
hostname) for TCP connections. (port=
port_number) for TCP connections. Default: false Since version: 5.1.15 includeThreadNamesAsStatementComment Include the name of the current thread as a comment visible in "SHOW PROCESSLIST", or in Innodb deadlock dumps, useful in correlation with "includeInnodbStatusInDeadlockExceptions=true" and
Oracle recommends configuring this callback attribute instead of setting the callback at runtime. It is possible to dynamically change the PDB within the same CDB. Beginning in Version 7, SAS software supports reading, updating, creating, and deleting DBMS tables. Initial Database for Connection If the database is not specified, the connection is made with no default database.
See "Enable Application Continuity" in Oracle WebLogic Server Administration Console Online Help. Details The LIBNAME statement associates a libref with a SAS/ACCESS engine in order to access tables or views in a DBMS. Default: false Since version: 5.0.4 useOldUTF8Behavior Use the UTF-8 behavior the driver did when communicating with 4.0 and older servers Default: false Since version: 3.1.6 useOnlyServerErrorMessages Don't prepend 'standard' SQLState error If you use the NamedPipeSocketFactory, the host name and port number values in the JDBC URL are ignored.
If KEYSET_SIZE=0, then the entire cursor is keyset driven. Application Continuity is not supported. Also be aware that, in this case, the list of generated keys returned may not be accurate. If BCP_ERRORFILE= is not specified, errors are not recorded during BCP processing. CONNECTION=SHAREDREAD | GLOBALREAD | UNIQUE indicates whether multiple table opens in a DBMS can use the same connection.
Default value: NO If USE_ODBC_CL=YES, the Driver Manager uses the ODBC Cursor Library. PROMPT= is similar to the COMPLETE= option. This is part of the legacy date-time code, thus the property has an effect only when "useLegacyDatetimeCode=true." Default: false Since version: 5.0.0 useLegacyDatetimeCode Use code for DATE/TIME/DATETIME/TIMESTAMP handling in result sets Default: true Since version: 3.1.7 maintainTimeStats Should the driver maintain various internal timers to enable idle time calculations as well as more verbose error messages when the connection to the server
If you specify USER=, you must specify PASSWORD=. Default: false Since version: 3.1.3 enableEscapeProcessing Sets the default escape processing behavior for Statement objects.
