RE: Another doubt in 9.0.1.0.0 database..

[Enrique Orbegozo]

Hi,

    There is a bug when you asign java_pool_size=0, it happened to me.

 

ORA-04031: no se han podido asignar 4032 bytes de memoria compartida ("shared po
ol","unknown object","joxs heap init","ioc_allocate_pal")

Metalink:

 

     fact: Oracle Server - Enterprise Edition 9.0.1
     symptom: ORA-00604: error occurred at recursive SQL level 1
     symptom: ORA-04031: unable to allocate %n bytes of shared memory ("
     shared pool",%s,%s,%s)
     symptom: ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 0
     symptom: ORA-06512: at line 4
     change: Java_pool_size <= 4M
     cause: <Bug:2084844>:
     ERROR OCCURRED AT RECURSIVE SQL LEVEL 1

 

fix:

 

Startup the database caused following errors logged in the alert file:

 

ORA-00604: error occurred at recursive SQL level 1
ORA-04031: unable to allocate 4032 bytes of shared memory ("shared pool&
quot;,
           "unknown object","joxs heap init","
ioc_allocate_pal")
ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 0
ORA-06512: at line 4

 

Afterwards, since the database is open, the errors also occur when creating or
dropping database objects (tables, external tables, ...), neverthenless with
slightly different parameters in the ORA-4031 error message, like:

 

ORA-04031: unable to allocate 4032 bytes of shared memory ("shared pool&
quot;,
           "unknown object","joxs heap init","
ioc_allocate_pal")

 

or

 

ORA-04031: unable to allocate 4032 bytes of shared memory ("shared pool&
quot;,
           "sun/misc/URLClassPathSYS","joxlod: in ehe",&
quot;ioc_allocate_pal")

 

or

 

ORA-04031: unable to allocate 4032 bytes of shared memory ("shared pool&
quot;
           "oracle/CDC/ChangeTableSYS","joxlod: in ehe",&
quot;ioc_allocate_pal")

 

The size of the shared pool doesn't influence the result. This means that
increasing the shared_pool_size will not solve the problem.

 

The problem is fixed, setting the java_pool_size greater then 4M. In fact a
value of 4194305 (4M + 1 byte) would be sufficient, since the java_pool_size is
adjusted to a multiple of 4M. In this case the java_pool_size would be 8M.

 

It seems that there is a threshold of java_pool_size of 5M based on v$sgastat.

 

Remark:
------

 

<Bug:2084844> is initially fixed in version 9.2.

Asunto: Another doubt in 9.0.1.0.0 database..

Hi DBAs,

While reducing the JAVA_POOL_SIZE in initfile.... , i observed that minimum it takes 8M and not less than that.

If we dont specify this parameter, default value it takes as 20 M !!.

If there is no JAVA related stuff in my application / database..., why should i have this space allocated.?

Moreover, this space allocation seems to be affecting the PGA size....!!

Any suggestions to make it NULL or zero. ??

Thank you.

regards,
Arul.
