SQL Server : Non-standard ports

When you connect to a server using a default instance configuration (e.g. "myserver"), the SQL client calls the server on the standard port: 1433. When you call a server using a named instance but lacking a port (e.g. "myserver\instancename"), the SQL client calls SQL Server's management service on port 1434. The management service replies with a dynamically assigned port (chosen at sql engine service startup) for the instance and the client connection proceeds using that new port. If the network firewall doesn't have either the management service port nor the dynamic port(s) open the connections fail. Using dynamic ports for SQL instances means that the instance names are like a SQL DNS system. They are simply there to help the server resolve a dynamic port. Once the port is resolved, the name is superfluous. You can use additional, and thus non-standard, ports for the additional SQL instances so as to know the ports so the firewall could be configured to allow them. Once you have a predefined port assigned to a named instance you no longer need the actual instance name for the connection but can simply connect using the server name (or IP) and port number, for example: "myserver,1432". Also you no longer need to run the SQL browser service on the server that provides the instance name lookup.

Oracle : 11GR2 - IGNORE_ROW_ON_DUPKEY_INDEX Hint

Silently ignore new rows that violate a single unique index.  The IGNORE_ROW_ON_DUPKEY_INDEX hint applies only to single-table INSERT operations. It is not supported for UPDATE, DELETE, MERGE, or multitable insert operations. IGNORE_ROW_ON_DUPKEY_INDEX causes the statement to ignore a unique key violation for a specified set of columns or for a SINGLE specified index. When a unique key violation is encountered, a row-level rollback occurs and execution resumes with the next input row. As with all hints, a syntax error in the hint causes it to be silently ignored. The result will be that ORA-00001 will be caused, just as if no hint were used. Ref Bulk operations? Multiple rows with same UK being inserted - which get in - arbitrary ?

Oracle : 11GR2 - Selected new features

Drawn from the 11GR2 New features doc Definitely Interesting 1.2.2.4 IGNORE_ROW_ON_DUPKEY_INDEX Hint for INSERT Statement 1.3.1.1 Analytic Functions 2.0 1.3.1.2 Recursive WITH Clause 1.3.2.2 Preprocessing Data for ORACLE_LOADER Access Driver in External Tables 1.5.2.1 E-mail Notification 1.5.2.2 File Watcher 1.5.2.4 Remote Database Jobs 1.5.3.1 Data Pump Legacy Mode Possibly Interesting 1.2.3.2 Configurable Real-Time Query Apply Lag Limit 1.9.2.3 Automatic Patching of Time Stamp With Time Zone Data 1.3.4.2 Minimal Effort Parallel Execution - Auto Degree of Parallelism (DOP) and Queuing 1.9.2.10 Enable Sampling for Active Data Guard 1.9.2.12 Global Oracle RAC ASH Report + ADDM Backwards Compatibility RAC - Possibly Interesting 1.4.1.6 Grid Plug and Play (GPnP) 1.4.1.7 Oracle Restart 1.4.1.10 Role-Separated Management 1.4.1.13 Enterprise Manager-Based Clusterware Resource Management 1.4.1.14 Enterprise Manager Provisioning for Oracle Clusterware and Oracle Real Application Clusters 1.4.1.17 Configuration Assistant Support for Removing Oracle RAC Installations 1.4.1.18 Oracle Universal Installer Support for Removing Oracle RAC Installations 1.4.1.22 Out-of-Place Oracle Clusterware Upgrade 1.4.1.26 SRVCTL Support for Single-Instance Database in a Cluster Definitely Interesting 1.2.2.4 IGNORE_ROW_ON_DUPKEY_INDEX Hint for INSERT Statement With INSERT INTO TARGET...SELECT...FROM SOURCE, a unique key for some to-be-inserted rows may collide with existing rows. The IGNORE_ROW_ON_DUPKEY_INDEX allows the collisions to be silently ignored and the non-colliding rows to be inserted. A PL/SQL program could achieve the same effect by first selecting the source rows and by then inserting them one-by-one into the target in a block that has a null handler for the DUP_VAL_ON_INDEX exception. However, the PL/SQL approach would take effort to program and is much slower than the single SQL statement that this hint allows. This hint improves performance and ease-of-programming when implementing an online application upgrade script using edition-based redefinition. 1.3.1.1 Analytic Functions 2.0 New and enhanced analytical functions are introduced in this release. A new ordered aggregate, LISTAGG, concatenates the values of the measure column. The new analytic window function NTH_VALUE (a generalization of existing FIRST_VALUE and LAST_VALUE functions) gives users the functionality of retrieving an arbitrary (or nth) record in a window. The LAG and LEAD functions are enhanced with the IGNORE NULLS option. The new and enhanced SQL analytical functions allow more complex analysis in the database, using (simpler) SQL specification and providing better performance. See Also: Oracle Database Data Warehousing Guide for details 1.3.1.2 Recursive WITH Clause The SQL WITH clause has been extended to enable formulation of recursive queries. Recursive WITH clause complies with the American National Standards Institute (ANSI) standard. This makes Oracle ANSI-compatible for recursive queries. See Also: Oracle Database SQL Language Reference for details 1.3.2.2 Preprocessing Data for ORACLE_LOADER Access Driver in External Tables The syntax for the ORACLE_LOADER access driver is extended in this release to allow specification of a program to preprocess the data files that are read for the external table. The access parameters can specify the name of a directory object and the name of an executable file in that directory object. When the access driver needs to read data from a file, it creates a process that runs the specified program, passing in the name of the data file. The output from the program is passed into the access driver which parses the data into records and columns. The initial use of this feature is by a customer who needs to load data that is stored in compressed files. The user specifies the name of the program used to decompress the file as part of the access parameters. The access driver reads the output of the decompression program. Large customers want to load data from compressed files which requires less disk space and uses the I/O bandwidth between the disk and memory more efficiently. 1.5.2.1 E-mail Notification Oracle Database 11g Release 2 (11.2) users can now get e-mail notifications on any job activity. This feature improves efficiency by enabling users to be notified of any job activity that is of interest to them without having to constantly monitor the job. 1.5.2.2 File Watcher File watcher enables jobs to be triggered when a file arrives on a given machine. This feature improves efficiency and ease-of-use. Jobs with file dependencies are automatically triggered when the specified file is received instead of constantly monitoring for the file. 1.5.2.4 Remote Database Jobs This feature enables users to run PL/SQL blocks or stored procedures that reside in a remote database as a job. This is a key feature for Enterprise Manager scheduling. It improves efficiency and ease-of-use by enabling job scheduling in a distributed environment to be managed centrally. 1.5.3.1 Data Pump Legacy Mode Data Pump Legacy Mode provides backward compatibility for scripts and parameter files used for original Export and Import scripts. This feature enables users to continue using original Export and Import scripts with Data Pump Export and Import. Development time is reduced as new scripts do not have to be created. Possibly Interesting 1.2.3.2 Configurable Real-Time Query Apply Lag Limit A physical standby database can be open for read-only access while redo apply is active only if the Oracle Active Data Guard option is enabled. This capability is known as real-time query. The new STANDBY_MAX_DATA_DELAY session parameter can be used to specify a session-specific apply lag tolerance, measured in seconds, for queries issued by non-administrative users to a physical standby database that is in real-time query mode. This capability allows queries to be safely offloaded from the primary database to a physical standby database, because it is possible to detect if the standby database has become unacceptably stale. 1.9.2.3 Automatic Patching of Time Stamp With Time Zone Data Time stamp with time zone data could become stale in the database tables when the time zone version file is updated. Today, users have to manually fix the affected data. This feature updates the system and user data transparently with minimal downtime and provides automatic and transparent patching of time stamp with time zone data whenever a time zone file is updated. Also, when a server time zone version is patched, all of the clients that communicate with the server need to be patched as well. With this feature, OCI, JDBC, Pro*C, and SQL*Plus clients can now continue to work with the server without having to update their client-side files. This new feature provides automatic and transparent patching of time stamp with time zone data whenever a time zone file is updated. 1.3.4.2 Minimal Effort Parallel Execution - Auto Degree of Parallelism (DOP) and Queuing When activated, Oracle determines the optimal degree of parallelism (DOP) for any given SQL operation based on the size of the objects, the complexity of a statement, and the existing hardware resources. 1.9.2.10 Enable Sampling for Active Data Guard Active Session History (ASH) is now available on standby systems. Having ASH data available on standby systems for Data Guard environments allows customers to troubleshoot performance problems specific to their standby environments. 1.9.2.12 Global Oracle RAC ASH Report + ADDM Backwards Compatibility The Active Session History (ASH) report now includes cluster-wide information, greatly enhancing it's utility in identifying and troubleshooting performance issues that span nodes for a cluster database. RAC - Possibly Interesting 1.4.1.6 Grid Plug and Play (GPnP) Grid Plug and Play (GPnP) eliminates per-node configuration data and the need for explicit add and delete nodes steps. This allows a system administrator to take a template system image and run it on a new node with no further configuration. This removes many manual operations, reduces the opportunity for errors, and encourages configurations that can be changed easily. Removal of the per-node configuration makes the nodes easier to replace, because they do not need to contain individually-managed state. Grid Plug and Play reduces the cost of installing, configuring, and managing database nodes by making their per-node state disposable. It allows nodes to be easily replaced with regenerated state. 1.4.1.7 Oracle Restart Oracle Restart improves the availability of your single-instance Oracle database. Oracle Restart automatically restarts the database instance, the Automatic Storage Management (ASM) instance, the listener, and other components after a hardware or software failure or whenever your database host computer restarts. Server Control (SRVCTL) is the command line interface to manage Oracle processes that are managed by Oracle Restart on a standalone server. This feature provides improved reliability and automated management of a single-instance Oracle database and the management of any process or application running on the database server. 1.4.1.10 Role-Separated Management Role-separated management for Oracle Clusterware allows certain administrative tasks to be delegated to different people, representing different roles in the company. It is based on the idea of a clusterware administrator. The administrator may grant administrative tasks on a per resource basis. For example, if two databases are placed into the same cluster, the clusterware administrator can manage both databases in the cluster. But, the clusterware administrator may decide to grant different administrative privileges to each DBA responsible for one of those databases. Role-separated management allows multiple applications and databases to share the same cluster and hardware resources, but ensures that different administration groups do not interfere with each other 1.4.1.13 Enterprise Manager-Based Clusterware Resource Management New in this release is an Enterprise Manager graphical user interface (GUI) to manage various Oracle Clusterware resources with full lifecycle support. In addition to allowing the creation and configuration of resources within Oracle Clusterware, it also helps to monitor and manage resources once deployed in the cluster. Using Oracle Enterprise Manager as a GUI to monitor and manage various Oracle Clusterware resources eases the daily management in high availability environments. 1.4.1.14 Enterprise Manager Provisioning for Oracle Clusterware and Oracle Real Application Clusters Enterprise Manager provisioning introduces procedures to easily scale up or scale down Oracle Clusterware and Oracle Real Application Clusters. Ease-of-implementation and management for a clustered database environment can be achieved through utilizing the terprise Manager provisioning framework. 1.4.1.17 Configuration Assistant Support for Removing Oracle RAC Installations Database Configuration Assistant (DBCA), Database Upgrade Assistant (DBUA), and Net Configuration Assistant (NETCA) have been updated to support the complete deinstallation and deconfiguration of Oracle RAC databases and listeners. This support improves the manageability of an Oracle RAC environment through automation of deinstallation and deconfiguration of Oracle RAC databases. 1.4.1.18 Oracle Universal Installer Support for Removing Oracle RAC Installations The installer can clean up a failed Oracle Clusterware installation or upgrade of an environment prior to reattempting the operation. This ensures that the reattempted operation is done over a clean environment, thereby eliminating the chances of errors related to environmental inconsistencies. Easily cleaning up an environment provides improved Oracle RAC manageability and deployment. 1.4.1.22 Out-of-Place Oracle Clusterware Upgrade A new version of Oracle Clusterware is now installed into a separate home from the current installation. This reduces the downtime required to upgrade a node in the cluster and facilitate the provisioning of clusters within an enterprise. The benefit is a reduction in planned outage time required for cluster upgrades which assists in meeting availability service levels. This also makes it easier to provide a standard installation across the enterprise. 1.4.1.26 SRVCTL Support for Single-Instance Database in a Cluster Using SRVCTL, you can register a single-instance database to be managed by Oracle Clusterware. Once registered, Oracle Clusterware starts, stops, monitors, and restarts the database instance. This feature provides an improved management interface which makes it easy to provide higher availability for single-instance databases that are running on a server that is part of a cluster. Fini

Oracle: DBCA template reverse engineering problem solved

Silent create template dbca -createTemplateFromDB -sourceDB lontestdb02:1521:NEWDEV4 -templateName ZPFL1 -sysDBAUserName sys -sysDBAPassword password -maintainFileLocations false -silent Problem When using the DBCA to create a RAC database when selecting next on the node selection screen are receiving the following error: java.security.AccessControlException: access denied (java.sql.SQLPermission setLog) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:270) at java.security.AccessController.checkPermission(AccessController.java:401) at java.lang.SecurityManager.checkPermission(SecurityManager.java:542) at java.sql.DriverManager.setLogStream(DriverManager.java:392) Cause The problem is that the user (oracle user) which use the DBCA does not have the permission to use the java packages for the RAC environment across the nodes. To create a file which set the permissions it will be checked and used to perform the action needed to be able to create the instances across the nodes Fix Create the file: .java.policy on each node in the Oracle Users Home directory. containing the following code. grant { permission java.security.AllPermission; }; When done, changed the permission to 770 for the .java.policy file for the files/nodes Start the DBCA again.

Oracle 10.2 RAC reboottime tweakables

http://mengmark.spaces.live.com/blog/cns!9BA8E9209B123692!179.entry Oracle Database 10g Release 2 CSS (Cluster Synchronization Service) parameters:   With different patch-sets of Oracle Database 10g Release 2; there exist different timeout parameters which are used by CSS while accessing storage data. In this document we will cover following Oracle Database 10g Release 2 patch-set versions: 1. Oracle Database 10.2.0.1 2. Oracle Database 10.2.0.1 + Patch for Bug 4896338 3. Oracle Database 10.2.0.2 4. Oracle Database 10.2.0.3   1. Oracle Database 10.2.0.1   There is only one CSS parameter available in this version of Oracle and it is called misscount which represents the maximum time in seconds that, a heartbeat can be missed before entering into cluster reconfiguration to evict the node, and the maximum time allowed for a voting file I/O to complete. The default value for misscount is 60 seconds.   2. Oracle Database 10.2.0.1 + Patch 4896338 and Oracle Database 10.2.0.2 There is bug 4896338 with Oracle Database 10.2.0.1 which is a placeholder bug for PCW 10.2.0.1 merge for very low brownout. Please refer www.metalink.oracle.com for more details. Oracle Database 10.2.0.2 has a fix for this bug. There are three CSS parameters available in 10.2.0.2 and 10.2.0.1 + patch for bug 4896338; they are as follows:   a) misscount - It represents maximum time in seconds that, a heartbeat can be missed before entering into a cluster reconfiguration to evict the node.   b) disktimeout - It is the maximum amount of time allowed for a voting file I/O to complete; if this time is exceeded the voting disk will be marked as offline.   c) reboottime - It is the amount of time allowed for a node to complete a reboot after the CSS daemon has been evicted.   Default values for these parameters are as follows: misscount = 60 seconds disktimeout = 200 seconds reboottime = 3 seconds Using "crsctl get css disktimeout / reboottime" will not show parameter value unless you modify it explicitly. You can check the parameter's values using ocssd.log under $CRS_HOME directory. 8 CRS internally calculates two parameters namely diskshorttimeout and disklongtimeout (can be checked in ocssd.log), where   a) diskshorttimeout = misscount - reboottime : This value is used during reconfiguration and initial cluster formation as a timeout for voting file I/O to complete.   b) disklongtimeout = disktimeout : This value is used during normal operation of RAC as a timeout for voting file I/O to complete.   3. Oracle Database 10.2.0.3   This version also has same parameters as that of Oracle Database 10.2.0.2; also the default values are same as Oracle Database 10.2.0.2. There is slight difference in the internal calculation of there parameter values; If disktimeout is less than the misscount value then during cluster formation and throughout cluster operation misscount - reboottime is considered as disktimeout and the modified parameter disktimeout is ignored. That is in Oracle Database 10.2.0.3 diskshorttimeout = disklongtimeout if css disktimeout parameter is less than css misscount.   4. Recommendations for Oracle Database 10g Release 2 CSS parameter values to be used with NetApp storage:   As diskshorttimeout = misscount - reboottime; and if misscount & reboottime are kept as default values i.e. 60 seconds & 3 seconds respectively; the time for accessing voting file will be considered as 57 seconds by CSS, so If the reconfiguration happens during the NetApp Storage takeover or giveback process there are chances of CRS reboot taking place; hence following are the recommended values for CSS timeout parameters for Oracle Database 10g Release 2 RAC to work smoothly during NetApp Storage takeover and giveback process. 1. Oracle Database 10.2.0.1 misscount = 120 seconds (default is 60 seconds) 2. Oracle Database 10.2.0.1 + Patch for Bug 4896338 misscount = 120 seconds (default is 60 seconds) disktimeout = 200 seconds (default) reboottime = 3 seconds (default) 3. Oracle Database 10.2.0.2 misscount = 120 seconds (default is 60 seconds) disktimeout = 200 seconds (default) reboottime = 3 seconds (default) 4. Oracle Database 10.2.0.3 misscount = 120 seconds (default is 60 seconds) disktimeout = 200 seconds (default) reboottime = 3 seconds (default) All the above recommendations are for Linux Operating system. Note: The stock version of Oracle database 10g Release 2 lower than 10.2.0.2 do not provide all the configurable CSS parameters; hence it is advisable to upgrade Oracle Database to 10.2.0.2 or higher.   Appendix Commands to check / modify CSS parameters: 1. crsctl get css misscount ---------- to check misscount value 2. crsctl get css disktimeout --------- to check disktimeout value 3. crsctl get css reboottime ---------- to check reboottime value 4. crsctl set css misscount 120 --------- to set misscount to 120 seconds 5. crsctl set css disktimeout 200 ------- to set disktimeout to 200 seconds 6. crsctl set css reboottime 3 ----------- to set reboottime to 3 seconds  http://el-caro.blogspot.com/2006/10/case-study-on-how-to-diagnose-node.html There have been a couple of additional CSS related parameters introduced in the 10.2.0.2 patchset to address long I/O requirements of storage vendors such as EMC and NetApp. • reboottime: (default 3 seconds) The amount of time allowed for a node to complete a reboot after the CSS daemon has been evicted. This parameter can be set via the command crsctl set css reboottime R [-force] (R is seconds) • disktimeout (default 200 seconds) The maximum amount of time allowed for a voting file I/O to complete; if this time is exceeded the voting disk will be marked as unavailable This parameter can be set via the command crsctl set css disktimeout D [-force] (D is seconds) These commands must be run as root on a node where the CRSD is up, unless '-force' is specified, in which case the the CRS stack should not be up on any other node. After the commands are run all CSS daemons must be restarted for the settings to take effect on all nodes asap. You can verify the settings by doing an ocrdump and checking the values in the OCRDUMPFILE

Office : Outlook Rule limits
