June 13th, 2020, posted in Oracle
Share

 

Features on this R12 INST_TOP

-All the logs files have been moved from APPL_TOP,ORACLE_HOME to this to top

  • All configuration files have been moved to INST_TOP
    like
    DBc file
    All the http related config files
    appsweb.cfg
    All the start or stop scripts
    all the OC4J related config files

-we can now share the Apps and technology stack among multiple nodes and even instances (Dev,Test, Production) as all the log and config are located in this top.We will have INST_TOP for each context.

-Configuration and log files are co-located

-Easier collection of instance state
-Minimize disk usage and maximize performance

Filesystem look

/inst/apps/ ($INST_TOP)
• /admin
• /scripts ($ADMIN_SCRIPTS_HOME) All the start and stop are here
• /appl ($APPL_CONFIG_HOME) All the apps env are here
• /fnd/12.0.0/secure ($FND_SECURE) dbc file lis located here
• /certs
• /logs ($LOG_HOME) all the logs are located
• /ora ($ORA_CONFIG_HOME)
/10.1.2
/10.1.3 ($ORACLE_CONFIG_HOME) all the techstack(oacore,forms) related config files
• /pids
• /portal
• /rgf

Some more changes to variable

OA_HTML =$COMMON_TOP/webapps/oacore/html
JAVA_TOP=$COMMON_TOP/java/classes
AF_JLIB=$COMMON_TOP/java/lib
JAVA_BASE=$COMMON_TOP/java/

Advantage  of INST_TOP

-Clear distinction between the shared file system and the file system unique to an instance
-Ability to share code (Apps, technology stack) among multiple  nodes and even instances (Development ,Test, Production)
-Enables split ownership of applications and technology stack file systems
-Improves code safety by making shared file system read-only while not patching
-Configuration and log files are co-located
-Easier collection of instance state
-Ability to use network or local storage for various file system portions
-Minimize disk usage and maximize performance

R12.2 Changes

-R12.2 contains the Fusion Middleware 11g tech-stack. The logfile and configuration files is located in that Oracle Home

–Concurrent Manager log/out files have been moved in Non editioned File system

Where to Put INST_TOP in shared file system

It is recommended to put INST_TOP on local filesystem  in shared APPL_TOP filesystem  architecture. This is because of the Apache mutex problem.Apache performance is highly sensitive to mutex file access latency, and at higher loads is also sensitive to I/Os per second. In case you have INST_TOP on shared filesystem, it is suggested to point these context variable to local file-system

s_lock_pid_dir
s_pids_dir
s_web_pid_file

 

 

Conclusion

Hope you like the post on R12 INST_TOP, all the advantages and R12.2 changes.  Please do provide the feedback.

Difference Between Bitmap and Character Mode Report

April 12th, 2020, posted in Oracle Queries
Share

Here is an example to help explain how Oracle Reports are designed and printed in both the bitmap and character-mode environments.Difference Between Bitmap and Character Mode Report, Occurred In Oracle Reports,Oracle Reports,Oracle,Reports,Difference Between Bitmap and Character Mode Assume you wish to print “Cc” where “C” is a different font and a larger point size than “c” and is in boldface type (where “c” is not). In Oracle Reports Designer, bitmap mode, you can make “C” bold and in a different font and point size than “c”.

This is because you are generating postscript output. Postscript is a universal printer language and any postscript printer is able to interpret your different design instructions. In Oracle Reports Designer, character mode, the APPLICATIONS STANDARDS REQUIRE the report to be designed in ONE FONT/ ONE CHARACTER SIZE. Character mode reports generate ASCII output.

In ASCII you cannot dynamically change the font and character size. The standard is in effect so a report prints as identically as possible from both conventional and postscript printers.
