Otherwise the next time when starting up redo apply again, you will encounter error ORA-01153.

How To Compile Forms In Oracle Application R12

We have to use frmcmp(Form Compiler) for compiling forms and libraries in Oracle Applications Version R12, But in 11i we need to use f60gen to compile forms and libraries which is deprecated in R12.

1) Login to application server.

2) Go to the directory $AU_TOP/forms/US

3) Place “.fmb” file in binary mode

4) Execute the below command to generate “.fmx”.

frmcmp_batch userid=apps/<apps_paswd> module=<Form_Name>.fmb output_file=<Form_Name>.fmx module_type=form batch=no compile_all=special

EXAMPLES:

frmcmp_batch userid=apps/apps module=RCVRCERC.fmboutput_file=$AU_TOP/forms/US/RCVRCERC.fmx module_type=form batch=no compile_all=special

 

R12 

frmcmp_batch userid=apps/apps 
module=/u01/apps/apps_st/appl/au/12.0.0/forms/US/XXXXXX.fmb 
output_file=/u01/apps/apps_st/appl/XX_CUSTOM/12.0.0/forms/US/XXXXXX.fmx 
module_type=form batch=no compile_all=yes 

R11 

f60gen Module= 
XXXXXX.fmb Userid=apps/apps Module_Type=FORM Module_Access=FILE 
Output_File=$XX_CUSTOM/forms/US/XX_CUSTOM.fmx Compile_All=special

Shared Memory Tuning: Startup database – ORA-27102: out of memory Linux-X86_64 Error: 28: No space left on device

ORA-27102: out of memory
Linux-x86_64 Error: 28: No space left on device
I have used RHEL X86_64 + memory (32GB) and setted sga_max_size=20G + sga_target=20G and …
$ cat /proc/sys/kernel/shmmax
26843545600
What wrong with my kernel tuning… So, I checked metalink (301830.1) and some recommend from RHEL
They told; set SHMALL to the total amount of physical RAM divided by page size.

SHMALL =>Total amount of shared memory available (bytes or pages)

then:
Check Page Size:
$ getconf PAGE_SIZE
4096
Determine the system wide maximum number of shared memory pages:
$ cat /proc/sys/kernel/shmall
2097152
My system 64bits with memory 32GB, then 1024 * 1024 * 1024 * 32 / 4096 = 8388608
So, change kernel.shmall = 8388608
$ su - root
# echo 8388608 > /proc/sys/kernel/shmall
Or modify /etc/sysctl.conf file:
kernel.shmall=8388608
and
# sysctl -p
After changed… check and startup database again:
$ cat /proc/sys/kernel/shmall
8388608
 
SQL> startup

.

.

.

--- NO ERROR ---
From this idea with memory 32GB
mem=$(free|grep Mem|awk '{print$2}')
totmem=$(echo "$mem*1024"|bc)
huge=$(grep Hugepagesize /proc/meminfo|awk '{print $2}')
max=$(echo "$totmem*75/100"|bc)
all=$(echo "$max/$huge"|bc)
echo "kernel.shmmax = $max"
echo "kernel.shmall = $all"
Result:
kernel.shmmax = 25213120512, kernel.shmall = 12311094
However, This case “ORA-27102: out of memory Linux-X86_64 Error: 28: No space left on device” , solved by set SHMALL = MemTotal(byte)/PAGE_SIZE
and …
I hope to hear your idea about kernel tuning with Oracle Database.
