# Classement croisé Purines vs Oméga‑3
| Aliment | Purines (mg/100 g) | Catégorie purines | Oméga‑3 (g/100 g) | Catégorie oméga‑3 | Verdict croisé |
|--------------------------|--------------------|-------------------|-------------------|-------------------|----------------|
| Poulet (blanc/cuisse) | 150–175 | Modéré | ~0.05 | Pauvre | ⚠️ Peu d’intérêt nutritionnel, purines modérées mais quasi pas d’oméga‑3 |
| Bœuf (muscle) | ~120 | Modéré | ~0.04 | Pauvre | ⚠️ Idem, faible en oméga‑3 |
| Foie de bœuf | ~300 | Très élevé | ~0.10 | Pauvre | 🚫 À éviter (purines très élevées, peu d’oméga‑3) |
| Sardine | ~210 | Élevé | ~0.80–0.90 | Moyen | ⚖️ Bon apport en oméga‑3 mais purines élevées |
| Anchois | ~300 | Très élevé | ~0.90 | Moyen | 🚫 Risque goutte, malgré oméga‑3 |
| Saumon | ~170 | Modéré | ~2.3–2.6 | Riche | ✅ Excellent compromis (oméga‑3 riches, purines modérées) |
| Maquereau | ~145 | Modéré | ~1.4–1.8 | Riche | ✅ Très bon compromis |
| Hareng | ~170 | Modéré | ~1.6–2.2 | Riche | ✅ Très bon compromis |
| Truite | ~150 | Modéré | ~1.2–1.3 | Riche | ✅ Bon compromis |
| Thon (rouge) | ~150 | Modéré | ~1.6–1.7 | Riche | ✅ Bon compromis |
| Crevettes | ~150 | Modéré | ~0.30 | Moyen | ⚖️ Correct mais pas exceptionnel |
| Crabe / Tourteau | ~150 | Modéré | ~0.45 | Moyen | ⚖️ Correct |
| Homard / Langouste | ~135 | Modéré | ~0.52 | Moyen | ⚖️ Correct |
| Moules | ~150 | Modéré | ~0.59–0.85 | Moyen | ⚖️ Correct |
| Couteaux de mer | ~150 | Modéré | ~0.6 | Moyen | ⚖️ Correct |
| Coquilles Saint‑Jacques | ~150–180 | Modéré | ~0.5–0.6 | Moyen | ⚖️ Correct |

@ Technical Tip: Clean up /boot in CentOS, RHEL or Rocky Linux 8 and up
1) Check the current kernel being used:
sudo uname -sr
2) List all kernels installed on the system:
sudo rpm -q kernel
3) Delete old kernels and only leave <X> number of kernels:
sudo dnf remove --oldinstallonly --setopt installonly_limit=<X> kernel
Note: <X> can be set to 1, 2, 3 or other numeric values. Carefully check the running kernel in step 2 and any other kernels used before running this command. Alternatively, use the following command to delete kernels one by one:
rpm -e <kernel_name>
Kernel names can be obtained through step 2.

subjectAltName = @alt_names
[ alt_names ]
DNS.1 = exegol.swgalaxy
DNS.2 = exegol
```
Create thr CSR:
``` bash
openssl req -new -key exegol.swgalaxy.key.pem \
-out exegol.swgalaxy.csr.pem \
-config exegol.swgalaxy.cnf
```
## Sign with Intermediate CA
Update `server_cert` extension on **intermediate CA** configuration file `/app/pki/intermediate/openssl.cnf`:
```
[ server_cert ]
# Basic identity
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid,issuer
# Server certificates must NOT be CA certificates
basicConstraints = critical, CA:FALSE
# Key usage: what the certificate is allowed to do
keyUsage = critical, digitalSignature, keyEncipherment
# Extended key usage: define this as a TLS server certificate
extendedKeyUsage = serverAuth
# Allow SANs (modern TLS requires SANs)
subjectAltName = @alt_names
[ alt_names ]
DNS.1 = exegol.swgalaxy
DNS.2 = exegol
```
Sign the certificate with **intermediate CA**:
``` bash
openssl ca -config /app/pki/intermediate/openssl.cnf \
-extensions server_cert \
-days 3650 -notext -md sha256 \
-in exegol.swgalaxy.csr.pem \
-out /app/pki/intermediate/certs/exegol.swgalaxy.cert.pem
```
## Verify the chain
``` bash
openssl verify \
-CAfile /app/pki/intermediate/certs/ca-chain.cert.pem \
/app/pki/intermediate/certs/exegol.swgalaxy.cert.pem
```
## Verify the certificate
``` bash
openssl x509 -text -noout \
-in /app/pki/intermediate/certs/exegol.swgalaxy.cert.pem
```

## XTTS
> Note MOS: V4 Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup (Doc ID 2471245.1)
### Initial setup
Identify tablespaces to transport, probably all non "administrative" tablespaces:
```
select
listagg(tablespace_name, ',')
within group
(order by tablespace_name) as non_sys_ts
from
dba_tablespaces
where
contents not in ('UNDO','TEMPORARY') and
tablespace_name not in ('SYSTEM','SYSAUX');
```
For source and target servers, define folders to be used for scripts, backupset, datapump etc.
In our case, that will be a shared NFS folder `/mnt/unprotected/tmp/oracle/xtts`
> The size of folder should be greather than the size of full database.
Unzip xtts scripts:
cd /mnt/unprotected/tmp/oracle/xtts
unzip /mnt/yavin4/kit/Oracle/XTTS/rman_xttconvert_VER4.3.zip
Configure xtt.properties file:
```
tablespaces=TS1,TS2,TS3,USERS
src_scratch_location=/mnt/unprotected/tmp/oracle/xtts/scratch
dest_datafile_location=+DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/xtts/
dest_scratch_location=/mnt/unprotected/tmp/oracle/xtts/scratch
asm_home=/app/oracle/grid/product/19
asm_sid=+ASM1
destconnstr=sys/"Secret00!"@ylesia-scan/adm_reek
usermantransport=1
```
On target server, create ASM directory where the datafile will be restored:
mkdir +DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/xtts
On **both source and target** servers, set `TMPDIR` environment variable to the path of xtts scripts:
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
### Prepare Phase
This step corresponds to initial full backup/restore of source database on target system.
Initial backup on source server:
```
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
cd $TMPDIR
$ORACLE_HOME/perl/bin/perl xttdriver.pl --backup --debug 3
```
Initial restore on target server:
```
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
cd $TMPDIR
$ORACLE_HOME/perl/bin/perl xttdriver.pl --restore --debug 3
```
> `debug` argument is optional
### Roll Forward Phase
As long as necessary we can do incremental backup/resore operations.
> New datafiles add to source database are automatically managed by this step.
The commands are exactly the sames (with or without debug mode).
For backup:
```
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
cd $TMPDIR
$ORACLE_HOME/perl/bin/perl xttdriver.pl --backup
```
For restore:
```
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
cd $TMPDIR
$ORACLE_HOME/perl/bin/perl xttdriver.pl --restore
```
> Running succesives backup or successive restore operations does not pose a problem.
### Final Incremental Backup
On **source** database, put tablespaces in **read-only** mode:
```
select
'alter tablespace '||tablespace_name||' read only;' as COMMAND
from
dba_tablespaces
where
contents not in ('UNDO','TEMPORARY') and
tablespace_name not in ('SYSTEM','SYSAUX');
```
Check:
```
select distinct status
from
dba_tablespaces
where
contents not in ('UNDO','TEMPORARY') and
tablespace_name not in ('SYSTEM','SYSAUX');
```
Take final incremental backup:
```
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
cd $TMPDIR
$ORACLE_HOME/perl/bin/perl xttdriver.pl --backup
```
Rstore final incremental backup:
```
export TMPDIR=/mnt/unprotected/tmp/oracle/xtts
cd $TMPDIR
$ORACLE_HOME/perl/bin/perl xttdriver.pl --restore
```
### Metadata export
Create DATAPUMP directory on **both** source and destination databases.
On source (non-CDB):
SQL> create or replace directory XTTS as '/mnt/unprotected/tmp/oracle/xtts';
On destination (PDB):
export ORACLE_PDB_SID=REEK
SQL> create or replace directory XTTS as '/mnt/unprotected/tmp/oracle/xtts';
Export metadata
expdp userid="'/ as sysdba'" dumpfile=XTTS:metadata.dmp logfile=XTTS:metadata.log FULL=y TRANSPORTABLE=always
### Optionally: on target, pout target datafiles read-only at OS level
Identify OMF target datafiles:
```
asmcmd -p
cd +DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/xtts
ls --permission
```
For each datafile, set read-olny permisions, example:
chmod 444 +DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/xtts/*
If you got:
ORA-15304: operation requires ACCESS_CONTROL.ENABLED attribute to be TRUE (DBD ERROR: OCIStmtExecute)
then set following diskgroup attributes and retry.
```
column dg_name format a20
column name format a50
column VALUE format a30
set lines 120
select
dg.name dg_name, attr.name, attr.value
from
v$asm_attribute attr
join v$asm_diskgroup dg on attr.group_number=dg.group_number
where
attr.name in ('compatible.rdbms','access_control.enabled')
order by dg.name, attr.name
/
alter diskgroup DATA set attribute 'compatible.rdbms' = '19.0.0.0.0';
alter diskgroup RECO set attribute 'compatible.rdbms' = '19.0.0.0.0';
alter diskgroup DATA set attribute 'access_control.enabled' = 'TRUE';
alter diskgroup RECO set attribute 'access_control.enabled' = 'TRUE';
```
> Compare number of datafiles transported and the number of datafiles of non-Oracle tablespaces
> Check if transported tablespaces already exists on target database
### Metadata import and tablespace plug-in
Create impdp parfile `impo_metadata.par`:
```

dumpfile=XTTS:metadata.dmp
logfile=XTTS:impo_metadata.log
transport_datafiles=

```
Run import:
impdp parfile=impo_metadata.par
Rebounce the PDB (or the CDB), otherwise we can get errors like:
```
ORA-01114: IO error writing block to file 33 (block # 1)
ORA-01110: data file 33:
'+DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/DATAFILE/ts1.298.1205060113'
ORA-27009: cannot write to file opened for read
```
Put plugged tablespaces in read/write mode:
```
select
'alter tablespace '||tablespace_name||' read write;' as COMMAND
from
dba_tablespaces
where
contents not in ('UNDO','TEMPORARY') and
tablespace_name not in ('SYSTEM','SYSAUX');
```
Remove aliases in order to user only OMF datafiles:
```
cd +DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/xtts
rmalias ts1_8.dbf ts2_13.dbf... .... ...
cd ..
rm -rf xtts
```
## Unxexpectd issues
In metadata import step I relize I forgot to include USER tablespace in `xtt.properties` and impdp failed wit error:
ORA-39352: Wrong number of TRANSPORT_DATAFILES specified: expected 13, received 12
The tablespace USER being in read-only mode I copied the datafile manually on target database.
Identify the file number:
```
SQL> select FILE_ID from dba_data_files where TABLESPACE_NAME='USERS';
FILE_ID
----------
7
```
Backup datafile on source:
```
run{
set nocfau;
backup datafile 7 format '/mnt/unprotected/tmp/oracle/xtts/%d_%U_%s_%t.bck';
}
```
Restore datafile on target;
```
run {
restore from platform 'Linux x86 64-bit'
foreign datafile 7 format '+DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/xtts//USERS.dbf'
from backupset '/mnt/unprotected/tmp/oracle/xtts/GREEDO_0i3t87ss_18_1_1_18_1205084060.bck';
}
```
Put datafile in read-ony at ASM level:
chmod 444 +DATA/AERONPRD/389011A6CB11A654E0635000A8C07D80/DATAFILE/USERS.302.1205084171
Run the impdp again.
## Troubleshooting
Having datafile to plug-in in read-only mode at ASM level allow to repeat tne impdp operations as many time as necessary.
For example, to completly re-execute the impdp metadata as on initial conditions:
- drop new plugged tablespaces
- drop non oracle maintened users
- run impdp metadata again
```
drop tablespace TS1 including contents;
drop tablespace TS2 including contents;
drop tablespace TS3 including contents;
drop tablespace USERS including contents;
select 'drop user '||USERNAME||' cascade;' from dba_users where ORACLE_MAINTAINED='N';
```
