Default Architecture of Apps11i
Implementation Methodology– With the widespread use of the Oracle Applications
for DOTCOMS and other small to midsize organizations, the physical disk availability (and usage) becomes a key factor.
– This article will discuss about how multiple databases like DVLP, CRP1, CRP2, CRP3, TEST, TRNG, PTCH can share common APPL_TOP’s and common ORACLE_HOME between them.
Implementation with 11i•Most of the implementation follows the following pattern
– Install the database and this requires 25 GB (for a small sized co.) with little room to breathe in R11i.
– Other install group (DEV, CRP1, CRP2, CRP3, PATCH, TRAINING ) presents the empty database install with its set of Technology stack and APPL_TOP. This requires approximately 22 GB.
– DEV instance starts with functional people gathering business requirements and showing the end users how what do they can be done using R11i
– Now we have CRP1, setup environment is shaped now with the help of consulting function members, by the client functional people
– CRP2 only client team do the setups and customization is invoked at this point
– CRP3 ( Pre production setups ) this goes to production. – PATCH instance is required for testing patches– TRAINING is required for training the end user community– Some other dev1, test1 environments
Hardware and Software Space Requirements•In Oracle Applications R11i, the robust size per installation set is close to 25 GB. Every APPL_TOP
management requires maintaining 14 set of scripts, almost 10 environment scripts, 3 ORACLE_HOME.ORACLE_HOME requirements
– As per 11.5.1 installation base have almost 3.5 GB space requirements for 8.1.6 , 8.0.6 , WEBDB home combined together.– Application Files Each application files , also called APPL_TOP requires almost 8 GB per install– Database Files Each install default database files are almost 8Gb
•Hardware and Software Space Requirements– By oracle default installation methodology it needs 2 UNIX logins per install and total of almost 20 GB. If there exists 5 to 7
environments for the implementation then the total of 120 to 150 GB space pre production is required.
Benefits– Can save lot of disk space (atleast 15 GB for sharing
two appl_tops and Oracle Homes)– Easy for the DBAs to maintain and monitor.– Time saving - since no need to run the patches in so
many instances in so many places.
METHODOLOGY•Each install has 3 oracle homes
– 8.1.6 is required for database– 8.0.6 is required for APPL_TOP files– webdb is required for webdb listener 2.5
Oracle HOME environment files – ORACLE.env
– Present under 8.0.6, 8.1.6 and webdb (2.5) home – <SID>.env file present under each home which calls
ORACLE.env as base setup file
WEBDB 2.2 listener – $ pwd
• /u01/apps/oracle/visora/8.0.6/listener
– Create a new directory for each oracle database attached to this oracle home • cfg cfg_<sid> log log_<sid>
– $ pwd • /u01/apps/oracle/visora/8.0.6/listener/cfg_<sid>
– wdbsvr.app , wdbsvr.cfg
– Modify DAD information and connect string in wdbsvr.app file
– wdbsvr.cfg file contents to point to our APPL_TOP
WEBDB oracle home, 2.5, listener files
– $ pwd• /u01/apps/oracle/visora/webdb/listener
– $ ls• cfg cfg_<SID> images images_<SID> log
log_<SID>
– $ pwd • /u01/apps/oracle/visora/webdb/listener/cfg_<sid>
– wdbsvr.app , wdbsvr.cfg
– Modify DAD information and connect string in wdbsvr.app file – Point wdbsvr.cfg file contents to point to our APPL_TOP
ENV files under APPL_TOP– $ pwd
• /u02/apps/11i/visappl
– $ ls *.env • create files called <SID>.env , APPLSYS_<SID>.env ,
APPSORA_<SID>.env
– Modify the APPLSYS_<sid>.env • FORMS60_WEB_CONFIG_FILE• FORMS60_MAPPING
– and APPSORA_<sid>.env file – APPL_TOP, OAD_TOP/html/bin– $ pwd
• /u02/apps/11i/viscomn/html/bin– $ ls– FNDWRR.exe appsweb.cfg.tmp pasta.cfg– appsweb.cfg appsweb_<SID>.cfg
Oracle Scripts Modifications
– start oracle scripts and then applmgr scripts– stop applmgr scripts and then oracle scripts– webdb 2.5 script file modification , adwdbctl.sh
• WV_GATEWAY_CFG• WDBLOG
– webdb 2.2 listener , adwlnctl.sh • FORMS60_WEB_CONFIG_FILE
