2.一个check_ccps.sh 检查待推送，监控上送，监控8999和返回代码为空的交易、检查是否对账、监控未对账。
可以执行以下检查：
- 检查待推送交易
- 监控上送交易
- 监控8999返回代码为空的交易
- 检查是否对账
- 监控未对账的交易
#!/bin/bash# Set variables
LOG_DIR=/var/log/ccps
WORK_DIR=/opt/ccps
CHECK_DATE=$(date +%Y%m%d)# Check for pending transactions
PENDING_COUNT=$(grep -c "Pending transaction" $LOG_DIR/ccps_${CHECK_DATE}.log)
if [[ "$PENDING_COUNT" -gt 0 ]]; thenecho "There are $PENDING_COUNT pending transactions."
fi# Monitor submitted transactions
SUBMITTED_COUNT=$(grep -c "Submitted transaction" $LOG_DIR/ccps_${CHECK_DATE}.log)
if [[ "$SUBMITTED_COUNT" -gt 0 ]]; thenecho "There are $SUBMITTED_COUNT submitted transactions."
fi# Monitor 8999 response code
NO_RESPONSE_COUNT=$(grep -c "Response code: " $LOG_DIR/ccps_${CHECK_DATE}.log | grep -c "Response code: [[:space:]]*$")
if [[ "$NO_RESPONSE_COUNT" -gt 0 ]]; thenecho "There are $NO_RESPONSE_COUNT transactions with no response code."
fi# Check reconciliation status
RECON_STATUS=$(grep "Reconciliation completed" $LOG_DIR/ccps_${CHECK_DATE}.log | tail -n1)
if [[ -z "$RECON_STATUS" ]]; thenecho "Reconciliation has not been completed."
elseecho "Reconciliation has been completed."
fi# Monitor unreconciled transactions
UNRECONCILED_COUNT=$(find $WORK_DIR -name "*_${CHECK_DATE}.txt" | wc -l)
if [[ "$UNRECONCILED_COUNT" -gt 0 ]]; thenecho "There are $UNRECONCILED_COUNT unreconciled transactions."
fi
该脚本假定CCPS系统日志文件名为
ccps_<DATE>.log，并且所有待处理的交易文件都保存在工作目录中。您需要根据实际情况更新变量LOG_DIR和WORK_DIR。该脚本通过搜索日志文件中的特定字符串来执行各种检查，并在发现问题时输出相应的消息。例如，如果有待推送的交易，将输出类似于“有X个等待处理的交易”的消息。
请注意，此脚本只是一个示例，并且可能需要根据您的具体需求进行修改和自定义。
Tips:
CCPS是“跨行交换清算系统”的缩写，是中国人民银行推出的用于实现银行间资金结算、交易清算和风险控制的统一平台。其主要功能包括支付结算、融资融券、黄金业务等。
CCPS通过建立一个统一的、高效的资金交换和清算机制，为银行业提供了更加便捷、安全、高效的资金结算服务，同时还可以起到监管和风险防控的作用。它支持多种付款方式，包括即时支付、定向支付、批量代发等，并且具有实时处理、高可靠性和大容量的特点。
在CCPS系统中，各家银行通过网络与CCPS系统进行连接，完成资金交换和清算。在交易过程中，CCPS系统将根据规则对交易进行审核和结算，保证交易的合法性和安全性。同时，CCPS系统还提供了实时交易监控和风险控制服务，能够及时响应各类异常情况和风险事件。
总之，CCPS是中国银行业重要的基础设施之一，为实现快速、安全、高效的资金结算提供了必要的支持。
3.check_database.sh 检查数据库是否处于打开状态、控制文件和日志文件是否正常、表空间是否在线、以及数据文件是否备份。
check_database.sh脚本，可以监控Oracle数据库的各种状态：
#!/bin/bash# Set variables
ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1
ORACLE_SID=orcl
LOG_DIR=/var/log/oracle# Check database status
DB_STATUS=$(echo "select status from v\$instance;" | $ORACLE_HOME/bin/sqlplus -S / as sysdba)
if [[ "$DB_STATUS" != "OPEN" ]]; thenecho "Database is not open."
fi# Check control file status
CONTROL_STATUS=$($ORACLE_HOME/bin/sqlplus -S / as sysdba <<EOF
set heading off feedback off verify off
select status from v\$controlfile;
EOF
)
if [[ "$CONTROL_STATUS" != "ONLINE" ]]; thenecho "Control file is not online."
fi# Check log file status
LOG_STATUS=$($ORACLE_HOME/bin/sqlplus -S / as sysdba <<EOF
set heading off feedback off verify off
select status from v\$logfile;
EOF
)
if [[ "$LOG_STATUS" != "VALID" ]]; thenecho "Log file is not valid."
fi# Check tablespace status
TABLESPACE_ALERT=$($ORACLE_HOME/bin/sqlplus -S / as sysdba <<EOF
set heading off feedback off verify off
SELECT t.tablespace_name, t.status FROM dba_tablespaces t WHERE t.status NOT IN ('ONLINE', 'READ ONLY');
EOF
)
if [[ -n "$TABLESPACE_ALERT" ]]; thenecho "One or more tablespaces are not online:"echo "$TABLESPACE_ALERT"
fi# Check datafile status
DATAFILE_ALERT=$(find $ORACLE_HOME/dbs -name "*.dbf" -type f -mtime +7 -exec ls -l {} \;)
if [[ -n "$DATAFILE_ALERT" ]]; thenecho "One or more datafiles have not been backed up in the last 7 days:"echo "$DATAFILE_ALERT"
fi
该脚本通过运行SQL查询或查找文件来检查数据库的各种状态。例如，它会检查数据库是否处于打开状态、控制文件和日志文件是否正常、表空间是否在线、以及数据文件是否备份。
请注意，此脚本只是一个示例，并且您可能需要根据您的具体需求进行修改和自定义。特别是对于tablespace的status判断以及datafile的备份情况判断，您需要根据实际情况来调整相应的阈值和条件。
4. 登录监控，check_login.sh脚本，可以监控Oracle数据库的登录情况：
#!/bin/bash# Set variables
LOG_DIR=/var/log/oracle
CHECK_DATE=$(date +%Y%m%d)
CHECK_TIME=$(date +%H:%M:%S)# Check for successful logins in the last hour
LOGIN_COUNT=$(grep -c "Successful login:" $LOG_DIR/listener.log | grep "$CHECK_DATE $CHECK_TIME" -C 60)
if [[ "$LOGIN_COUNT" -gt 0 ]]; thenecho "There were $LOGIN_COUNT successful logins in the last hour."
fi# Check for failed logins in the last hour
FAILED_COUNT=$(grep -c "Failed login:" $LOG_DIR/listener.log | grep "$CHECK_DATE $CHECK_TIME" -C 60)
if [[ "$FAILED_COUNT" -gt 0 ]]; thenecho "There were $FAILED_COUNT failed logins in the last hour."
fi# Check for locked accounts
LOCKED_ACCOUNTS=$($ORACLE_HOME/bin/sqlplus -S / as sysdba <<EOF
set heading off feedback off verify off
SELECT username FROM dba_users WHERE account_status = 'LOCKED';
EOF
)
if [[ -n "$LOCKED_ACCOUNTS" ]]; thenecho "The following database accounts are locked:"echo "$LOCKED_ACCOUNTS"
fi
该脚本通过搜索数据库监听器日志文件来检查成功和失败的登录次数，并在必要时输出相应的消息。它还查询数据库中的所有用户账户状态，以查找已锁定的账户。
请注意，此脚本只是一个示例，并且您可能需要根据您的具体需求进行修改和自定义。特别是对于登录时限、账户锁定的阈值等，需要根据实际情况来设置相应的参数。
5。写一个check_fund.sh异常退款
#!/bin/bash# Define variables for connecting to the database
DB_USER="username"
DB_PASSWORD="password"
DB_NAME="database_name"# Define variables for sending email notifications
EMAIL_FROM="sender@example.com"

refund_count=$(sqlplus -S ${DB_USER}/${DB_PASSWORD}@${DB_NAME} <<EOF
set feedback off;
set pagesize 0;
select count(*) from refunds where status='abnormal';
exit;
EOF
)# Check if refund count is greater than zero
if [ $refund_count -gt 0 ]
then# If refunds are abnormal, log the issue and send an email notificationecho "$(date '+%Y-%m-%d %H:%M:%S') - Abnormal refunds detected: $refund_count refunds" >> /var/log/check_fund.logecho "Please investigate and take appropriate action immediately." | mail -s "$EMAIL_SUBJECT" -r "$EMAIL_FROM" "$EMAIL_TO"
fi

trade_status=$(sqlplus -S ${DB_USER}/${DB_PASSWORD}@${DB_NAME} <<EOF
set feedback off;
set pagesize 0;
select status from trades where id='$1';
exit;
EOF
)# Check if trade status has changed
if [ "$trade_status" != "$2" ]
then# If trade status has changed, log the issue and send an email notificationecho "$(date '+%Y-%m-%d %H:%M:%S') - Trade status changed: trade id=$1, old status=$2, new status=$trade_status" >> /var/log/check_trade_status.logecho "Please investigate and take appropriate action immediately." | mail -s "$EMAIL_SUBJECT" -r "$EMAIL_FROM" "$EMAIL_TO"

CURRENT_MONTH=$(date +%m)
CURRENT_YEAR=$(date +%Y)# Get name of partition to be cached
PARTITION_NAME="$PARTITION_PREFIX$CURRENT_YEAR$CURRENT_MONTH"# Check if partition exists and is not already cached in the In-Memory column store
partition_count=$(sqlplus -S ${DB_USER}/${DB_PASSWORD}@${DB_NAME} <<EOF
set feedback off;
set pagesize 0;
select count(*) from user_tab_partitions where table_name='$TABLE_NAME' and partition_name='$PARTITION_NAME' and inmemory_size=0;
exit;
EOF
