Here's a way to add a line to the beginning of a file:
sed -i '1s!^!set timing on\n set time on\n set echo on\n!' batch1.sql_bkp
find . -type f -name '*.sql' -exec sed -i '1s!^!set timing on\n set time on\n set echo on\n!' {} \;
sed -i '1s/^/line_to_be_added\n/' file
Then, you could use the code above with find to achieve your ultimate goal:
find . -type f -name '*.js' -exec sed -i '1s/^/line_to_be_added\n/' {} \;
Development is suggesting you to apply fix of Bug 33304775 - IPCDAT Errors - IBV Resources are Used for Processes Which Have No Need of Them ( Doc ID 33304775.8 ) There is no workaround, you will need to apply the fix. I'm checking for an available fix for you Per Dev findings: ============= The suspicion here is that RMAN is forking DB processes which are using a libcell context/IPCDAT context/QPs that are created by RMAN. Due to a potential kernel issue, the child does not inherit the security context of the parent correctly (it does a deep copy as expected, but the ibverbs specific code is only doing a shallow comparison of the security context pointer). If that happens, any ibv_modify_qp() call by the child will hit an EACCES for QPs created by RMAN. The fix is to make sure that RMAN does not create QPs at all (it should not need to, since it does not do IOs with the cell directly). Bug 33304775 prevents processes from creating QPs unnecessarily, and could help with this issue. ============= We had a couple of questions for you.. 1. Is this issue reproducible 100% of the time when you try restoring this DB? if yes, how much time does it take from the time the restore is started.. 2. Do you see the same issue across other DBs that you're migrating to 19c? 3. Are there any other DB or OS processes that are impacted during the same time ? We can try and arrange a Zoom with rman development and Commvault support during US hours if this issue is easily reproducible. Also here is other information that Engg is requesting.. First, if the CommVault software changes uid or gid or any other process credential during runtime. Second, 1. Copy the attached dtrace script trace.d to the node where they launch RMAM. The dtrace script will log a message for every attempt to change uid or gid. 2. Run “dtrace -s trace.d > /tmp/dtrace.out”. 3. Reproduce the issue. a. While commVault/RMAN are running, capture the output of “cat /proc/<pid>/status” periodically, where <pid> is the pid of commVault and RMAN. 4. Once the issue is reproduced, collect the following: a. The output of “dmesg -T”. b. The ExaWatcher PS data from the period -- /opt/oracle.ExaWatcher/archive/Ps.ExaWatcher/ /c. var/log/audit/audit.log d. /var/log/messages e. /tmp/dtrace.out f. The periodic dump of “cat /proc/<pid>/status” from Step 3a |
The default timeout values are:
300 seconds for TCP listeners.
60 seconds for HTTP listeners.

XML Publisher Report Bursting Program (XDOBURSTREP) Performance Poor While Initializing ( Doc ID 2300674.1 )You can use AWS Database Migration Service (AWS DMS) to migrate your data to and from most widely used commercial and open-source databases such as Oracle, PostgreSQL, Microsoft SQL Server, Amazon Redshift, Amazon Aurora, MariaDB, and MySQL. The service supports homogeneous migrations such as Oracle to Oracle, and also heterogeneous migrations between different database platforms, such as Oracle to MySQL or MySQL to Amazon Aurora MySQL-Compatible Edition. The source or target database must be on an AWS service.
In this guide, you can find step-by-step walkthroughs that go through the process of migrating sample data to AWS:
Migrating an On-Premises Oracle Database to Amazon Aurora MySQL
Migrating an Amazon RDS Oracle Database to Amazon Aurora MySQL
Migrating an Amazon RDS for Oracle Database to Amazon Redshift
Migrating a MySQL-Compatible Database to Amazon Aurora MySQL
Migrating a MariaDB Database to Amazon RDS for MySQL or Amazon Aurora MySQL
In the DMS User Guide, you can find additional resources:
