SPARC-T5 is a relatively new hardware model, so it is not very friendly to ORACLE 10G support. When installing ORACLE 10G in SPARC-T5, there are some special places that need to be done.

1. In order to actively avoid / prevent problems related to DISM (Dynamic Intimate Shared Memory), we strongly recommend that you disable DISM if the SGA size of the database is greater than 4G. Please refer to Document 1606318.1 for more information.

two。 In a Solaris 10 environment with a large number of CPU, there is an interoperability problem between the memory management of Solaris 10 and the automatic PGA memory management of Oracle. This problem can cause CPU to peak in random intervals and increase system CPU time. For corrective actions, see Document 460424.1.

Solution: set pg_contig_disable=1

3. Solaris 10 and Solaris 11 Systems on sun4v Platforms May Hang or Encounter a Deadman Panic (document ID 1411516.1)

SPARC Platform:

Solaris 10 with patch 147440-09 or later

Solaris 11 with SRU 11/11 SRU 02a or later

$pkg info entire | grep Summary

$pkg search 147440 | grep 147440

4. SUN's T-series machines use the "threading model" to make it look like there is more CPU than the machine actually has. For Oracle, the number of CPU on these Cool Threads machines (in this case, a machine with 32 processors) is actually eight times the number of system CPU (eight threads per kernel), so we will automatically set CPU_COUNT to 256and then DB will not open. The solution here is to manually set CPU_COUNT to a reasonable value (such as 16 or 32, etc., depending on the actual number of processors).

Install 10gR2 on Solaris 64 bits fails with: 'library-ldce: not found' (document ID 333348.1)

- -

SOLUTION

To implement the solution, you can use the patch for the bug or use a workaround:

A) Use the patch

1. Download patch 4589082 and apply it following instruction in README file

2. Install 10.2 software

B) Use the workaround

1. Rename / usr/lib/libdce.so to other name

2. Do installation

3. Rename back the file in step 1.

# Patch Installation Instructions:

#--

#

# Please note that this patch is applied to the Installation Software rather

# than an ORACLE_HOME

#

# 1) Preparing Oracle Installation Software for patching

#

# If the Oracle Installtion Software media is:

#-DVDs/CDs

# Copy the software inside DVD/CD to some directory inside

# the local hard disk (will be refered as SHIPHOMES_LOC from here

# on). If you have more than one Oracle Installation Software

# DVD/CD, create a new subdirectory for each of the DVDs/CDs and

# copy the DVD/CD contents into that directory.

#-Downloaded from OTN or any other Authorized site

# Unzip or Unarchive the software to some direcory inside the

# local hard disk (will be refered as SHIPHOMES_LOC from here on).

#

# 2) Patching Software

#

# Go to the directory containing patch and do:

#

# bash$ unzip p4589082_10201_SOLARIS64.zip

# bash$ cd 4589082

# bash$ export SHIPHOME=

# bash$. / p4589082.sh

Relink Errors During 10.2.0.5 Patchset (document ID 1190843.1)

- -

2 option to try to solve the problem.

1) deinstall the 10.2.0.5 Advanced Security Option component, this workaround is only valid if

The Advanced Security Option is not used in the RDBMS ORACLE_HOME.

. / runInstaller

Deinstall product

-deinstall the Advanced Security Option component (You can find this component under "Enterprise Edition Option")

-relink oracle

2) 10201-> 10204-> 10205 on Oracle Sparc Solaris 64 bit systems where / usr/lib/libdce.so exists

Then the following workaround must be used:

Rename following files before invoking 10205 patchset runInstaller:

$ORACLE_HOME/lib/libncds10.a

$ORACLE_HOME/network/install/ldflags.cds

$ORACLE_HOME/lib/libndce10.a

$ORACLE_HOME/network/install/ldflags.dce

Starting the Database with SGA_TARGET set Fails with ORA-27123 (document ID 552633.1)

- -

SOLUTION

1. Please check whether the following parameter is set: shmsys:share_page_table=1

# grep-I shmsys / etc/system

2. If it is set, then remove it from the / etc/system file and reboot the box.

3. Try to startup the database again with the desired sga_target

Prctl-n project.max-sem-ids-I project user.root

Prctl-n process.max-sem-nsems-I project user.root

Prctl-n project.max-shm-memory-I project user.root

Prctl-n project.max-shm-ids-I project user.root
