The SGATARGET initialization parameter reflects the total size of the SGA. Table 2 3 lists the SGA components for which SGATARGET includes memorythe automatically sized SGA componentsand the initialization parameters corresponding to those components. Table 2 3 Automatically Sized SGA Components and Corresponding Parameters. SGA Component. Initialization Parameter. Fixed SGA and other internal allocations needed by the Oracle Database instance. NAThe shared pool. SHAREDPOOLSIZEThe large pool. LARGEPOOLSIZEThe Java pool. JAVAPOOLSIZEThe buffer cache. DBCACHESIZEThe Streams pool. STREAMSPOOLSIZEThe parameters listed in Table 2 4, if they are set, take their memory from SGATARGET, leaving what is available for the components listed in Table 2 3. Table 2 4 Manually Sized SGA Components that Use SGATARGET Space. SGA Component. Initialization Parameter. The log buffer. LOGBUFFERThe keep and recycle buffer caches. DBKEEPCACHESIZEDBRECYCLECACHESIZENonstandard block size buffer caches. DBn. KCACHESIZEIn addition to setting SGATARGET to a non zero value, you must set the value of all automatically sized SGA components to zero to enable full automatic tuning of these components. Alternatively, you can set one or more of the automatically sized SGA components to a non zero value, which is then used as the minimum setting for that component during SGA tuning. This is discussed in detail later in this section. Note. An easier way to enable automatic shared memory management is to use Oracle Enterprise Manager EM. When you enable automatic shared memory management and set the Total SGA Size, EM automatically generates the ALTER SYSTEM statements to set SGATARGET to the specified size and to set all automatically sized SGA components to zero. If you use SQLPlus to set SGATARGET, you must then set the automatically sized SGA components to zero or to a minimum value. The VSGATARGETADVICE view provides information that helps you decide on a value for SGATARGET. For more information, see Oracle Database Performance Tuning Guide. Enabling Automatic Shared Memory Management. To enable automatic shared memory management If you are migrating from a manual management scheme, execute the following query on the instance running in manual mode to get a value for SGATARGET. SELECT SUMvalue FROM VSGA. SELECT CURRENTSIZE FROM VSGADYNAMICFREEMEMORY. SGATARGET. Set the value of SGATARGET, either by editing the text initialization parameter file and restarting the database, or by issuing the following statement. ALTER SYSTEM SET SGATARGETvalue SCOPESPFILEMEMORYBOTH. SGA component sizes and SGAMAXSIZE. For more information on the SCOPE clause, see Using ALTER SYSTEM to Change Initialization Parameter Values. Do one of the following For more complete automatic tuning, set the values of the automatically sized SGA components listed in Table 2 3 to zero. Do this by editing the text initialization parameter file, or by issuing ALTER SYSTEM statements similar to the one in step 2. To control the minimum size of one or more automatically sized SGA components, set those component sizes to the desired value. See the next section for details. Set the values of the other automatically sized SGA components to zero. Do this by editing the text initialization parameter file, or by issuing ALTER SYSTEM statements similar to the one in step 2. For example, suppose you currently have the following configuration of parameters on a manual mode instance with SGAMAXSIZE set to 1. M SHAREDPOOLSIZE 2. MDBCACHESIZE 5. MLARGEPOOLSIZE2. MAlso assume that the result of the queries is as follows. SELECT SUMvalue FROM VSGA 1. M. SELECT CURRENTSIZE FROM VSGADYNAMICFREEMEMORY 2. M. You can take advantage of automatic shared memory management by setting Total SGA Size to 9. M in Oracle Enterprise Manager, or by issuing the following statements. ALTER SYSTEM SET SGATARGET 9. M. ALTER SYSTEM SET SHAREDPOOLSIZE 0. ALTER SYSTEM SET LARGEPOOLSIZE 0. ALTER SYSTEM SET JAVAPOOLSIZE 0. ALTER SYSTEM SET DBCACHESIZE 0. ALTER SYSTEM SET STREAMSPOOLSIZE 0. M 1. 20. 0M minus 2. Oracle Forms Reports 1. R2 Installation Overview and Key Points. This post covers high level overview of Forms Reports 1. R2 installation. Installation Document of 1. R2 1. 1. 1. 2. 0 Forms Reports is available here. Oracle Forms Reports consists of. Oracle Formsa Forms Builder required for development and compilation of formsb Forms Server run time server used to deploy forms application and execution of forms. Oracle Reportsa Reports Builder required for development and compilation of reportsb Reports Server run time server used to deploy reports application and execution of reports. Latest release as of April 2. Oracle Forms Reports is 1. R2 1. 1. 1. 23. Installation Type You can install Forms Reports in two type. Install Configure You can install and configure forms reports at same time using installer. Install Software Do Not Configure You can install just forms reports software and do not configure them via installer. You later configure forms reports by running ORACLEHOMEbinconfig. Configuration Type You can configure forms reports in two ways. Configure for Deployment In this option you configure Forms Reports and also configure Oracle HTTP Server OHS including Enterprise Manager. In this configuration you also get option to integrate Forms Reports with Identity Management Components OID, OAM 1. Use this option for Production Type installation. Configure for Development In this option you configure Forms Reports but without OHS and Enterprise Manager. You also dont get an option to integrate Forms Reports with Identity Management Components OID, OAM 1. Use this option for Development Type installation. Integrating Forms Reports with IDM You can integrate Forms Reports with OID 1. LDAP types and version check Certification Matrix . OAM or OSSO can be used to integrate Forms Reports for Single Sign On. More on OAM 1. 1g in my book at Amazon. Forms Reports in deployment mode will createa Web. Logic Domain with Admin Sever and two managed servers WLSFORMS WLSREPORTS more on Web. Logic domain hereb Oracle Instance managed by OPMN with Forms, Reports, EM, and OHS7. You will need to install Web. Logic Software 1. Middleware Home More on MWHOME, ORACLEHOME, ORACLEINSTANCE or DOMAINHOME here 8. You must install Forms Reports Software under Middleware Home MWHOME created during Web. Logic Installation. This step will create ORACLEHOME for forms reports. Use run. Installer for Unix and setup. Disk. 1 of software. You can integrate Oracle Identity Management components OID OAM at configuration stage select configuration type Deployment, select OHS and select Application Identity Store Access ControlNote You can integrate Forms Reports with Oracle IDM OID OAM later as well using steps mentioned here. OAM can be configured in OPEN, SIMPLE or CERT mode more in my book here then you must register OAM Agents manually from Forms Reports node. To check Forms use http host portformsfrmservlet and for Report http host portreportsrwservletwhere port isa For deployment mode port os OHS listen port or Web. Logic Managed server listen port of respective serversb For development mode port is Web. Logic Admin Server port. Here is little quiz for readers Is it possible to install Forms on one server and reports on different server.
